Padlocks principles of Construction and unlocking
2010-3-6 16:03:38
Each padlocks has a different structure on the Department, which determines its function different. For the principle in terms of unlocking the vast majority of unlocking the lock is the same principle, in addition to magnetic card locks, electronic locks and other part of the lock exception.
Ordinary lock, such as the common gate built-in lock, padlockss, computer key, cross-shaped gate built-in lock, etc. ....., Although their style, structure, size, key-holes are not the same, but the lock principle is identical. As the saying goes: "they never deviate from them!
"These locks unlock the reason why the same principles, mainly because they are spherical in shape, the lock heart. Studied physics knows that only the circular object can freely rotate. Square, flat is the object can not be free to rotate.
According to experts in a certain lock repair 20 years of hard study locks, dismantling a number of no less than 10000 locks, lock type, model tens of thousands, careful analysis and exploration, summed up the principles and many of unlocking the lock-related experience. Whatever the style, type of lock, as long as the lock from the lock body and heart of two major parts of the lock structure, which locks heart must be spherical in shape. Who can not change this principle. Then another few decades, for centuries, no one can alter this principle.
On the classification of so much principle of unlocking the lock is locked in the circular object making a fuss about the heart. First, the lock hearts are hard metal used to produce. So, everyday Why do people use locks are based on copper to produce it? With copper copper heart, this is a certain reason. Copper is not easy rust, copper and iron and other metal will not stick knot adhesion. Copper is harder in texture and has a good toughness, prone to breaking. There is also a small number of manufacturers is to use stainless steel lock heart. Stainless steel high cost to the general manufacturers do not adopt. However, some manufacturers in order to save material, reduce costs, use of copper to produce aluminum alloy lock heart. Caused by a bad lock easily, lock heart easily broken, it is not desirable. In addition, the use of copper wall there is an advantage of lock-heart is hard to oxidation. Brass padlocks heart lock even be hanging in the open air under the sun and rain for a long time, although not a good opening, but as long as a few drops of oil (such as kerosene, engine oil, it is best sewing machine oil) activities, a few will be able to open a using the lock function recovery as ever.
Secondly, in the circular lock mind drilling a few small holes, and then lock heart with a small hole at the corresponding position of the lock body are also drilling the same number and size of the same caliber of small holes. The role of small holes is used to sub-and spring-loading. (A small hole in the lock body is used to sub-and spring-loading, while the lock hole called the heart of the marbles). Usually, we lock body and mind of a small hole in the lock hole known as marbles. So, the role of the marble is used to jam the lock heart, so that mind can not just lock rotation.
Therefore, regardless of the lock body and lock the body in the shape of how different organs, but play a major role in unlocking principle is to lock heart, marbles and spring. When the lock hole and lock the body of the billiard billiards heart hole completely coincide, the lock body billiards hole stretch to play a role in the spring, the lock body hole marbles out of the marbles up top. Lock body marble top hole of the marbles have been locked into the heart marbles hole. Heart lock hole the original marble marbles at the same time is up top. Because heart lock key hole has a long convex of stuck, blocking the lock hole of the marbles marble heart, so that is not billiards billiards orifice ejection, the take off out. Lock manufacturers have calculated the length and lock marble heart marble hole depth. Generally must be locked and the lock body hole billiard billiards heart hole and the length of the two marbles marbles hole depth is greater than the lock heart lock heart of convex billiards orifice to the long length. And the lock hole of the marbles marble heart must be greater than the length of the lock openings to the long convex billiards heart of the length of over 1 / 3. In this way, the lock hole of the marbles marble heart with long protruding orifice stuck without being top of prolapse marbles hole, then the lock body hole marbles marbles under the action of the spring there is part of the length of the roof into the lock hole marbles heart. Lock body of marbles marble hole cards into the lock hole, while marble heart, that is, heart lock jammed, and so on then stuck a circular object, so that objects can not be free to turn round. At this point, the lock is in locked state, is not an unusual say "lock the." However, in the extension key into the lock heart keyhole, the key to the lock on the alveolar heart billiards are also within the marbles down the compression, just lock hole of the marbles marble heart full overwhelmed, flattening the lock hole of another heart billiards faces of the mouth, (the lock and the lock body orifice heart billiard billiards orifice of the contact surface), then lock the body all the marbles marble hole being locked in heart billiards billiards hole downward pressure role, but also all been flattened the lock body orifice marbles, marbles back to the lock body hole. At this time, the lock body marbles into the hole of the marbles can not be card lock heart billiard hole, lock hole heart marbles under the pressure of the marbles were not depressed the lock body of the marbles into the hole, that is not something stuck round Lock heart. Then the key can be used to reverse the heart to turn the lock, the lock after the heart was driven rotation within the lock body organs, to unlock. This is the principle of unlocking. So, as long as its round lock heart lock unlock the same principle.
Turn-key lock is carried out. Why is the same key to open the same lock it? In the previous section has outlined the lock when the state is the key to the lock body hole marbles all the marbles whole heart and squeezed back into the lock openings to lock the contact surface of the body billiards when the heart can twist the lock to open the lock. This determines the key to be able to lock themselves in the hole all the marbles marbles back to full pressure contact area (lock body and lock heart), you can play a lock function. Because manufacturers lock out of its hole in the lock body marbles marbles are the same size, the length of the same, while the lock hole of the marbles marble heart size is not necessarily equal to the length of the same. This determines the corresponding keys are concave concavity of the depth of alveolar difference. For example, a five alveolar accordance with the general key to the lock with the key corresponding to the first must be the lock body has a heart and lock five marbles hole (except for card micropyle) in the lock hole and lock the body of the billiard billiards heart Kong Coincidence connected into five marbles holes, each hole has a spring billiards, two marbles.
Ordinary people from the inside looking outward into the key holes, with the eyes visible row of marbles collectively referred to as the first tablets of marble. Was first particle billiards billiards pore pressure in the following is referred to as the second tablets of marble. Each one has its own use of marble.
Heart lock hole of the first tablets of marble marbles of different lengths, determine the key differences also determine the same key to open the same lock this logic.
After stretching the key in the keyhole, the key groove on every one every one is aligned with a marble. The first grain marbles long, in the corresponding keys on the depth of the deep concave alveolar; On the contrary, the key on the depth of the shallow concave alveolar. May wish to disassemble a lock to observe the analysis would realize that.
The first and second tablets of marble marble tablets are closely linked and mutually conditioned. The length of the first tablets of marble or not determines the second tablets of marbles can be spring jacking lock heart marble hole depth. That first long, marble tablets, which share the location of the lock hole heart, the more marbles. This lock hole left heart billiard room less, then the second particle billiard billiard heart can enter the lock on the shallow depth of hole. On the contrary, the first words of a short marble tablets, and the second particle billiard can enter the lock hole concentration of mind on the deep marble.
Understanding of the knowledge of the above, we have fully understood the same key to open the same lock truth.
Lock Factory manufactured products in accordance with the specifications of the standard calculation, such as a five-toothed ordinary door key, which locks the same probability as 2 ‰, is also one out of every 500 in the same type of lock allows the same two locks, keys also the same.
Ordered learned people will know, the two numbers (not the same figure), there are two different permutations, the number of 6 three different permutations, four the number of 24 different permutations, the number of 120 different types of 5 arrangement, 6 the number of 720 different kinds of arrangement,
... .... Array formula: n. (n-1). (N-1), n> 1 (n is from a few numbers).
The formula used in the above-mentioned arrangement of the marbles arranged on the lock, only to lock the first tablets of marbles in the first tablets of a fixed length of time are carried out. So, if a change in the length of the first tablets of marble, its sequencing results is different, arranged in increasing the number of. Analogy it: to make an arrangement of four marbles, which filled four billiard long grain length requirement for the first 2 mm. Second grain length 3 mm, the third grain length 4 mm, the fourth grain length 5 mm. Ordered 24 of its results. If we replace the four marbles to make another arrangement, the first grain length 2.5 mm, and the second grain length 3.5 mm, the third grain length 4.5 mm, the fourth grain length 5.5 millimeters a result, another 24 ordered.
Through the above example we can see a lock hole marbles more, coupled with changes in the length of the different marble, its keys and locks, the less likely the same. But many manufacturers in the production of locks, are used to the length of the provisions of the marbles within a certain range of the model, the production, not to give full play to the length of the first changes in the role of marble tablets, to a certain extent, increases the probability of the same key.
General, produced by the lock manufacturer, at least two teeth of the gear-type key, the largest of 16 tooth-shaped keys. The lock hole within the marbles more keys on the number of alveolar followed the more, the stronger performance of its insurance. On the contrary, the number of keys on the alveolar less the more the weak performance of the lock of insurance. The first tablets of different marbles determines the key not the same. If a wrong key, it is impossible to open the lock. Manufacturers in the production of locks, the general provisions of the second tablets of marble is equal to the length of the first tablets of marble is a fundamentally different long. Its marbles are arranged determines the arrangement of keys on the alveolus. If with the same lock to mobilize the lock body and lock hole of the marbles marble heart, you can put a lock tune into dozens, hundreds, even thousands of different locks. Transferred into the lock of their number and arrangement of drill holes, marbles result is the number of the same.
Key features ordinary people to use the key to life is generally produced using copper or aluminum, but also useful for production of iron (iron is the key to making the outer layer of chrome plating to prevent rust).
Production of key materials used are better toughness of the metal, it is not easy breaking keys, able to withstand the thousands, tens of thousands, even hundreds of thousands of times to open. Of course, can not rule out a wrong key was to force the key to unlocking a result of easy to break situation.
Bump keys in addition to alveolar side of things, in its front there is a long-shaped concave alveolar (some keys have two or three long grooves). Syria has been described in the preceding a key role on the concave, then it's a long groove, what effect? In fact, the key to the long groove and the lock on the key hole of a long heart-shaped convex section is a pair of collocation. Keys on the long-groove just to accommodate the lock key hole heart of long-Cam. If the different manufacturers of locks, which lock the key hole of a long heart-shaped convex section is different from the corresponding keys on the long grooves are not the same. That is just the same as a factory produced 100% of the Insert key in order to get into the same type of keys, there may not be stretching the key lock key hole (in the previous manufacturers across the country the key to the ordinary door built-in lock models are produced according to certain specifications, it is basically the same).
Has already been described in the preceding heart lock key hole of the role of long-Cam is used to block the lock hole of the marbles marble heart, so that billiards billiards orifice can not fall off a lock to the keyhole outside the heart. If the marbles all the marbles fall off a heart lock hole, the marble will lose the lock jammed heart function.
In addition, the way hole spring and then describing the marble effect. As we all know, spring has the function of a rebound contraction. When locked in the locked state, the spring on the rebound reflects its function, the second tablets of marbles up top shells, so that the second bullet grain bullet hole into the lock heart marbles and played the card jammed lock heart bolt effect. When stretching the key lock heart keyhole, the spring is embodied in its systolic function. It is in the contraction process at the same time, the same is a rebound in nature. Such a situation will hinder first tablets of marble has been a key teeth on the concave under pressure to enter the lock body billiards hole role. Production lock, spring-loaded locking themselves in billiards the outer end of the post hole sealed with something. (For built-in lock locks like there is no such cover, but they lock the body shell also play a seal coat effect.) Blocks the normal use of material is generally an aluminum alloy, but also copper or stainless steel.
For people rarely used as an ordinary padlocks, if there are five billiard heart lock holes, the lock body there are six marbles holes. Why set up a billiard addition of the lock body hole then? Disassemble a padlocks to see if it will find out the reason. In the heart of the circular outer lock on an arc-shaped grooves Turtle. This is an arc-shaped groove with the lock body is just more of that inside the hole corresponding to a marbles. The width of the arc-shaped groove with this many marbles out of the hole diameter is the same length. In the lock body of this multi-hole marbles out of a long iron into a billiards (called a card, place marbles), and aluminum materials to seal filling holes into the billiard billiard remaining long position, so that this billiards is not in grain length, fixed-card die and the card lock into the curved grooves in the heart. The device is very necessary. It has played the role of the fixed lock heart to heart can not lock the lock in the lock body within the heart inside and outside the hole to move or go off, only for in-situ rotation.
In addition, the arc-shaped grooves and a billiards and card bit is to control the padlocks key to reversing the effects of the maximum, only within a certain range of degrees to reverse back and forth. This can be overcome easily turn the key off Long has reversed back to its original location, and to reduce the lock to reverse heart damage caused by friction, the lock will not be easy or bad. So, the key to reverse the degree of close ties with the curved groove. Lock mind the longer the length of the arc-shaped groove, the key to reverse the greater the degree; the other hand, the key to reversing the smaller degree. In fact, the arc length of the groove and lock the outer circumference of a long heart ratio the greater the scope of the key to reverse the greater the degree, which is a directly proportional relationship, you can use the following formula to calculate the key to reversing the greatest degree: n ° = arc-shaped groove length × 360 ° (n is the key to reversing the greatest degrees). Heart lock system of the external circumference of a long general padlocks manufacturers, they all provided the length of the arc-shaped groove lock heart accounted for 20% of the external circumference of a long period, that is the key to the padlocks can be reversed up to 72 °, for the built-in lock like that there is no arc Long-shaped grooves this setting, so the key can be freely without restriction degree turn. The vast majority of locks in the structure is much the same, are from the lock body, lock heart springs, marbles, etc. of parts. Although a variety of locks appearance, size vary, but to understand their respective structures were in place, that is, they never deviate from one of the principle of unlocking.
