Intelligent Combination lock and other Combination lock still exist the following problems:
1, complicated. Because the lock itself is a mechanical card resistance organizations, the so-called high-tech intelligent electronic lock ultimately depend on mechanical movement to complete. The electronic lock must complete the mechanical action - Electronic Identification conversion and electronic control -- machinery to implement this series of process. is obviously more complex.
2, reliability is poor, the failure rate is relatively high. More electronic devices, circuit complexity is bound to increase the chance of failure, coupled with electronic devices afraid of damp, fear of magnetic power, fear of strong vibration, the use of the environment of requirements. And mechanical lock through a number of measures to avoid those weaknesses.
3, the electronic lock can not do without electricity. The early power Combination lock are more general use city electricity. The present low power consumption IC electronic lock, a button battery can maintain control over part of the work, but driving electromagnets or they require large number of motor battery or use electricity. In some developed countries, there is the need to address waste batteries and environmental pollution faced by the environmental protection.
4, electronic lock can not do without additional spare keys and other means of mechanical lock. Most of the electronic lock mechanical lock bodies have adopted full-back.
It is recognized that electronic lock can not be separated as the executing agency of the mechanical lock, lock status of the whole machine will not be completely replaced by Combination lock, it locks the whole machinery of the past few years has been neglected.
Structure of the traditional mechanical wheel locks are widely used in safes, file cabinets, security doors, silver garage doors, warehouse door. Even a high degree of electronic intelligent bank ATM automatic teller machines, the wheel structure also use the back door The high-grade mechanical lock box, rather than use of Combination lock, safes are also China's exports most of Europe and the United States use this lock.
The wheel structure of the traditional mechanical locks there are also unable to overcome the shortcomings:
1, the operation complicated. With three-piece wheel structure of the ordinary mechanical lock, for example, need to be positive and negative spin the last ten laps to good password. If we adopt the United States, "Luojia Da", "alluvial gold" category of the code and unlock a knob operation using the same structure of high-end wheel mechanical combination lock box, confidentiality, although the increase, but the addition of an auxiliary disc, the operation is even more complicated. unlocking, you must also turn off multi-turn disrupt the password to achieve lock.
2, the password input is not easy. As the knob to rely on the precise scale to distinguish between the edge of your password, by turning the small knob to determine the password exact angle of the slightest mistake could enter the error come to naught.
3, password less. With three-piece structure of high-end wheel mechanical lock box as an example, assume that knob
Engraved on the edge of 100 calibration, three-piece should have a nominal 1003 = 1 million group password, but in fact never reached. Because with the rotary knob on the password, But, turning the hand to accurately distinguish between a scale (3.6 degrees) is very difficult, coupled with the impact of machining errors, it is impossible to accurately according to a scale value of the code.
In order to ensure the success rate of a password, you must allow sufficient margin structure. Therefore, the structure of the traditional mechanical wheel lock in the code that allow not more than ± 1.5 (1.25) a scale difference, which is approximately 2 Multi-scale as a valid value. while the knob on the verge of re-calibration precision scale is only 100 to effectively scale value even have 50, then the three-piece can only be 503 = 12.5 million units password. is far from a small password in the nominal amount, if the password in order to increase the volume of a four-piece, it will be more complicated operation.
Although the structure of various traditional mechanical wheel locks the above shortcomings, but it features all the mechanical structure to protect its reliability, can replace it in the absence of full mechanical lock cases, such products blossom everywhere, despite the use of over a hundred years, still has a long life cycle.
Now, a wheel structure, while maintaining the traditional mechanical lock all the advantages they had overcome their lack of mechanical lock - dial-disc full-mechanical lock to enter the market has already begun.
DIP disc applied to the whole machine locks safes, file cabinets, magnetic fire cabinets, security doors, silver garage doors, warehouse doors, doors, doors and mechanical jamming of civilian agencies widely used. It can replace the existing part of the Combination lock and all the mechanical structure of the traditional wheel locks, for certain product update provides an opportunity. because it overcomes some of the electronic code lock and the structure of traditional mechanical wheel lock some of the defects.
This is a simple operation, excellent performance, wide range of applications of the wheel body cassette mechanical high-security locks. Its unlocking manner as old-fashioned dial telephone dial-up. Unlock when the starting point from the dial, clockwise rotating dial to a certain one digital, and then counter-clockwise back to the starting point to enter a password, so repeat the last one until you enter your password. and then reset the dial counter-clockwise rotation to just point and you can unlock. unlock Sync automatically remove the PIN. clockwise rotating dial back to the starting point from the ending point and the lock bit is automatically closed, you must re-enter the password to unlock. If they lose in the wrong password, reset the dial counter-clockwise rotation to the stop point bits ( Password Clear), and then re-enter the password lock.
This lock has 6 (8) a wheel, with 6 (8)-digit password. Can be 6 (8) freedom of choice within the median number of passwords, random password number of the order, all arranged password combination from the user can easily set and change passwords frequently. according to dial the 12 or 23 numeric scale identification division of the standard grade 6 password lock key is greater than 3.25 million of its group, precision-level lock of the dense key is greater than 148 million group; 8-bit password locks the standard level is greater than 400 million of its key groups, key lock precision level is greater than
78 billion group, are a valid password. Lock with anti-damage re-lock mechanism; can choose the digital positioning mechanism installed to improve password input speed to achieve fast lock; cut using conventional technology, the possibility of unauthorized unlocking; the safety and reliability is better than other mode locks. You can also increase in demand based on the user interface alarm.
The mechanical structure of the traditional high-end wheel lock in the unlocking need counterclockwise, a clockwise rotation repeatedly and carefully align the number of laps scale, representative of the product is the United States Luojia Da, alluvial gold production by companies such as UL certified security, confidential, reliable, high-security mechanical lock box. is mainly used for bank ATM machines, commercial safes, treasury, defense, public security and other specialty industries vital parts of the door, use of personnel are mostly professionals, such as accounting, important documents , materials, warehouse personnel, etc. custody. However, because of the complicated mode of operation limits its scope of application.
DIP disc locks the whole machine is not only a bank ATM machines, safes, treasury, defense, public security and other specialty industries vital part of an exclusive lock on the door, or a universal application for all of life and property, provide a safe and to ensure high reliability, availability of high-grade security locks. For example: for bank teller machines, safe use "dial-disc full-mechanical lock" can also be installed on the anti-theft security door or home door, because has a good operational performance , all the people will use, eliminating the need for people to carry large amounts of drag lock keys, as long as remember your password, you can unlock the door.
DIP disc locks the whole machine has the wheel of today's most reliable high-grade structure, mechanical lock all the good characteristics, while creative simple mechanical structure design and can be used to unlock the password-fits-all quick and fast input method of unlocking mode of operation. its performance and scope of application than traditional high-end wheel structure, the mechanical lock.
DIP fully mechanical lock disc's advantages are: 1, no keys, no power, no batteries, no waste pollutants, .2, full mechanical structure, can withstand very harsh external environment, the use of a wide range of .3, simple operation , lock time is short, the average lock time is about 15 seconds .4, the actual password large amount of confidential high-performance, testing the unlock almost zero probability of .5, simple structure, robust and reliable .6, synchronize automatically removed by unlocking the password, dial back to the starting point from the ending point and the lock bit is automatically closed.
From the operating speed on the comparison, dial-lock disc full mechanical operation of less efficient push-button electronic lock, but the structure than the traditional mechanical wheel lock shortcut multiple. From the operational safety point of view contrasts than the mechanical push-button locks, and electronic push-button combination lock is much more secure; from the key quantitative comparison, more than the traditional mechanical lock a few times or even more, the key is close to the amount of Combination lock. From a practical point of view has been more than a full; from the use of reliability and service life on the comparison, the electronic lock can not compete with them. Moreover, the dial-disc full -
Mechanical lock to protect the entire mechanical structure of its reliability and environmental protection. Unlocking means unity brings high confidentiality. The law of product development from a technical perspective, a similar situation in the functional, simple is always the alternative to complex . Therefore, it is the practicality of mass products, replacing the traditional mechanical wheel lock structure, and some electronic code lock is inevitable.
