The lock industry has always been a wide range of products. As a practical tool for security and theft, it must be continuously improved and continuously updated in order to combat unlocking tools and other technical opening methods. Although the existing locks are various in variety and the shape and structure are very different, the internal structure of the lock cylinder is more and more complicated, but the technical principle of most mechanical locks is not fundamentally different, and the mutual restraint ability between the lock core members is low. Achieve the effect of preventing technical unlocking.
The Ministry of Public Security industry standard GA/T73-1994 mechanical anti-theft lock standard, the level of technical opening time mutual opening rate is: A. not less than 1 minute and not more than six thousandths. B. Not less than 5 minutes and not more than 6/10,000. It is not difficult to see that the anti-theft function of the ordinary mechanical lock is only limited to a relative range. This kind of commonality is not very complicated. The "technical opening method" is widely spread in the private sector. Any qualified mechanical lock can be "illegal" technically opened with anti-locking tools, as long as the time for "illegal" opening is prescribed. Within the scope of the product is qualified.
For many years, the R&D personnel in the lock manufacturing industry only made a fuss about the shape and structure of the lock core attachment. The operation methods are similar. They are not completely from the perspective of technical opening, and use reverse thinking to develop between the lock core components. The principle of restriction makes it easier to use technically open or simple destructive opening with anti-locking tools. The patented technology of ZL200620053041.8 invented by Xu Weiliang broke through the bottleneck of the inertia technology of the industry, and analyzed and solved the problem from the perspective of anti-destruction and anti-technical opening. The purpose of the patented technology is to provide a new type of mechanical lock with strong mutual restraining ability, simple structure, low manufacturing cost, convenient use, safety and reliability, and the key passage and rotating device of the ordinary mechanical lock. The card pin and the like adopt a mutual layer isolation technology in visual and operation methods, and cannot be opened abnormally by using an anti-locking tool (such as a simple special wrench or an electric drill) and a technical opening method.
The quality of the lock is generally examined from the aspects of safety, anti-theft, appearance, etc. At present, the security door, the car and other locks have industry standards, but the national standard for locks is still based on the current bottleneck of inertial technology, which gives The promotion of patented technology brings good opportunities. A large number of high-end buildings and luxury commercial housing have emerged, which has greatly stimulated the consumption demand of locks. The current annual sales of China's lock industry has reached 30 billion yuan. With the development of several pillar industries such as housing and automobiles in China, the further expansion of the lock industry market will bring more opportunities to enterprises. The "ball rear mechanical lock and key" developed by Xu Weiliang will open up a broad market with its unique technology, and drive the innovation and development of the whole industry.
