Locks are the most dependent on the property protection of all walks of life in the society. But the degree of insurance for locks is the most worrying. The weakness of the lock is that the electronic lock is either affected by factors such as power failure, weak current, humidity, etc., or is decoded by the decoder; the computer also has a disorder. The weakness of the lock is more: the lock hole is straight, the bullet is exposed, the keyhole is obvious, the obstacle setting is too small, the structure is simple, the password is low, the mutual opening rate is high, and it is easy to be stolen.
The branching technique in the market is even more "magic height", which is varied. In addition to special unlocking tools such as “unlocker†and “master keyâ€, steel wire, iron sheet, chewing gum, toy mud and even cardboard can be unlocked. More advanced, you can use the sorghum vibration to unlock at will. Coupled with the proliferation of inferior manufacturing, there is almost no mechanical lock that can't be opened. A good lock is just an extension of the unlock time. Password locks are no exception. Electronic locks can't sit back and relax. In addition to being expensive, once they are affected by environmental factors or computer turmoil, they can't even lock themselves; and decoding is threatening. Make the locks a "frustration choice" that the people rely on and worry about. Some people joked: "Which is only a gentleman, not a villain."
China's lock industry and lock market are facing the squeeze of foreign companies, and foreign locks have flooded into the Chinese market. Hotels, hotels, and warehouses are still relying on imports and are controlled by foreign locks. Domestic cars are still using ordinary locks. In foreign countries, locks are generally more expensive than doors, but the price of our general door locks is only a few tens of dollars, and even a few yuan can buy a lock. The shoddy and high mutual opening rate is restricting the development of the industry. There is a pull gate lock, and the mutual opening rate is almost over 25%. The industry standard is only 0.53 percent. There has also been a strange phenomenon in which the industry is getting bigger and bigger and profits are getting lower and lower. Some experts pointed out: "If the quality and insurance performance of our locks are no longer good, and we will work hard to develop, China's lock market will be lost." At the "3rd China International" Lock Industry Annual Meeting, the relevant parties emphasized that it is necessary to develop China's "lock-up power into a lock-up power." This is the development direction of China's lock industry and the goal of struggle.
In view of the weaknesses and difficulties faced by the locks, it is possible to have a lock with reliable performance and high quality and low price, to solve problems for the public, and to protect the wealth, it is the common voice of the people.
"Password double-chamber stable bead lock", ("bead" is a marble), is a lock that should be heard. Its core component, the design of the active lock cylinder, gives the lock a high degree of insurance performance and anti-theft function, making up for the weakness of the lock. This lock core has eight or more level barriers, two or more insurance, twenty to four hundred passwords, twenty to six hundred insertion routes, four to eighteen marbles, and a total of five to seven large groups of codes. The password can be up to more than 10 billion, at least 30,000, and the mutual opening rate can be zero.
This lock cylinder is designed with inner and outer chambers (as shown in the diagram) (see attachment): the outer chamber is called the “password insurance zoneâ€. The transform combination of the convex teeth is the composition of the password. Each tooth plate cavity has at least one convex tooth, usually three to four convex teeth. There are two hundred to four hundred sets of such passwords composed of convex teeth. Each key plate has a notch corresponding to the convex tooth. After the key enters the outer cavity, it must be turned at an angle to enter the inner cavity. This forces the key plate to pass the "validation" of the cryptographic teeth at the aisle of the outer cavity. If the switch cannot pass, the cavity cannot be inserted. The convex tooth is hidden behind the first keyhole and it is impossible to see its distribution at all.
