However, the good times are not long. In just one or two years, the first generation of idling locks has gradually withdrawn from people's field of vision. The dealers are stunned and locked, and then a lot of users use their original keys to open their own locks. Open, the industry analysts: users have returned, dealers are afraid to buy goods because of the congenital shortage of the first generation of idling locks, such as idling locks fear of dust, rain and oil, because the idling small organs inside the lock core, by Extremely small sets of springs and key blocks, locking side posts, locking pins, locking cards and other precision components work together and rely on the bevels on the sides of the grooves on the blades or marbles to open the locks, so dust, rain, etc. It is easy to affect the normal functioning of the idling chain, even if lead powder or dust remover is provided in the package of the idling lock.
Resurrection and exploration of the rebirth of idling locks The 40th issue of the technical exchange column of the journal published the article by Li Jijun of the Huai'an Public Security Bureau and the handsome article of the Blue Shields and Locks, “The Causes and Countermeasures of Technology Unlocking Theftâ€: Promote anti-theft locks with high anti-destructive ability and cannot be opened by technology, such as idling locks, etc." This article explains the public security department and the lock industry's recognition of the advantages of idling locks and anti-technical opening, but how to make idling locks overcome their own insufficiency Returning to the market is a difficult problem in front of the lock industry. Many people have designed dozens of patented technical solutions, and they are looking for the idling problem of the idling lock to the owner and the thief. But no one dares to It is very difficult to convince the dealers to re-sell the sales of the idle locks, for example, by adopting a small improvement such as canceling a small spring or adding a bevel. The phenomenon of manufacturers waiting to see and the merchants are afraid of it seems to make the idle locks painted. The full stop, so we must find another way, jump the technical solution with the idling lock, and pull out a
Another way, the idling lock ushered in the vast world from the earliest invented idling locks in the United States to various types of idling locks in China. The idling and non-idling actions are mainly caused by the key block (the gamma lock) or the locked side column (the gold point atom lock). Decide (other types of idling locks are similar), for example, insert the lock cylinder with the original key, align the blades or marbles, press the spring into the groove of the blade (the 玥 lock) or press the spring to push the rim Into the groove of the marble (gold point atom lock), the key block can drive the outer lock core to rotate to complete the unlock (the gamma lock), or lock the side column translation so that the lock pin rotates after the lock core rotates to complete the unlock (gold point atom lock) If the idling is a non-original key inserted into the lock cylinder, the blades or the marbles cannot be aligned. The compression spring cannot press the key block or the locking side column into the groove of the blade or the marble, so the key block stays in the outer lock core and can only be idling (the gamma lock ), or the lock pin stays in the rear lock cylinder and the inner lock core can only be idling (gold point atom lock). Therefore, the idle lock working according to the above principle must add many small precision parts and small springs in the narrow space of the lock core, which is complicated in structure and difficult to process, especially the small pressure bomb is easy to fatigue and change the elastic force; the dust enters and makes The loss of function of parts and so on is the main cause of the inadequacy of the first generation of idling locks, indicating that theoretical success does not mean success in practice.
The second generation of idling locks and the first generation of idling locks are two completely different technical solutions and completely different theories. They are mainly composed of rotary propellers, telescopic couplings and damping devices. The biggest features are: It does not change the internal structure of the existing lock cylinders, so it does not increase the difficulty and precision of the lock core manufacturing. Various lock cylinders can be cited; Second, it does not relate to the internal parts of various lock cylinders, so it does not affect The anti-technical opening structure and service life of the original lock cylinder; the third and third components are isolated from the outside world, so they are not worried about the entry of dust and rain; Fourth, they do not use small parts and springs, so the structure is simple, manufacturing and overall assembly are easy. .
The structure of the second generation idling lock is: the tail of the lock core is provided with a rotary propeller, followed by a telescopic coupling, the mutual contact surface is concave-convex or cam-shaped or spiral, and the damper device is installed in the lock core housing and the lock body. between.
The principle of the second generation of idling lock is: the original key rotates the lock cylinder, so that the rotary propeller rotates synchronously, and pushes the telescopic coupling to drive the lock tongue to complete the opening action. Rotating the lock cylinder with a non-original key or a screwing tool, the screwing force is transmitted to the lock core housing because the lock cylinder cannot rotate, and when the tightening force exceeds the damping force, the lock core housing can only be idling in the lock body, and the telescopic linkage is not Extend the bolt, so you can't drive the bolt to complete the unlocking action.
To make a simple metaphor: If the lock core is divided into two parts, the part where the key is inserted is the front part, and the part where the key is not inserted is the back part. The author calls these two parts the inner palace (front part) and the harem. (The latter part), the idling structure of the first generation of idling locks is set in the inner palace, the idling structure of the second generation of idling locks is located in the harem, the harem and the vestibule line clearly do not interfere with each other, the inner palace wants the harem to do what, harem It must be done, and the inner court and the harem of the first generation of idling locks are mixed together. If you encounter problems (dust), you don’t know who is obeying.
The author has now referenced the device of the idling lock to various mechanical locks such as door locks, emergency locks for fingerprint locks, safety locks, traffic locks, electric door locks, car locks, car door locks and tail box locks (except password locks). ), can design and manufacture second-generation idling locks for enterprises such as door industry, safe deposit box, traffic lock industry, car lock industry, car lock industry, etc., so that the idling device plays a major role in preventing technical opening and riot prevention, and developing people A safe, secure lock.
Afterword: The standard of locks should be adapted to the needs of the society. The author has read two articles in the 40th and 41st issues of the journal, including Li Jijun of Huai'an Public Security Bureau and Qi Dian of the Blue Shields: "Technical Unlocking Stealing Causes and Countermeasures" The security risks of the password safe (box). As the insiders deeply feel and feel the same, the author himself is both a locker and a consumer of locks. Locks are very important for everyone's safety. The relevant state departments should issue new anti-theft locks (including emergency locks) standards and Standards such as security doors and safes, which use high and low standards and comprehensively included standards to classify various locks into different categories and sub-levels, so that customers can know what to expect when purchasing locks according to product standards and requirements. Manufacturers and merchants should also publish standards and standards that are not met, and publish them on products and instructions.
For example: 1. Anti-technical opening: A, B, C, D... (based on the time when the locksmith expert uses the advanced unlocking tool to open the lock);
2, anti-riot screw: A, rigidity (based on kg / m);
B. Flexibility (subject to the presence or absence of idling function);
3, anti-drilling: (with the electric drill to the diameter of the drill bit diameter);
4, anti-mite: (to open the tool and open time);
5, anti-saw: (based on the hardness of the saw blade and the sawing time);
6. Anti-shear: (based on ordinary shear, hydraulic shear and shearing force).
The gradual introduction of the above standards has forced enterprises to develop and manufacture sophisticated anti-theft locks to meet the needs of the society. Do not let the people install a strong luxury security door and the lock core is vulnerable; expensive fingerprint locks and high-grade electronic lock boxes The emergency lock forms a dummy gentleman lock; hundreds of thousands of yuan rewards the technically-opened anti-theft lock to resist the twists of a few seconds... Therefore, the relevant state departments should fulfill their responsibilities and let the people stop being fooled by all kinds of anti-theft locks. The industry standard of the team can only breed the company to meet the status quo and not make progress, and it will not promote the development of the industry. People are expecting that the old standards that cannot keep up with the times and the locks that the thieves miss will become history.
Second generation idle lock
The earliest invention of the idling lock was Charles Hall, Virginia, USA in 1988. For various reasons, it was not commercialized. In 2002, after fourteen years, Kenneth Lille of the United States invented an idling lock. However, it has not yet formed commercialization. The real commercialization is Li Shande and Lei Xianming, the leading figures in the lock industry in China. Li Shande, who became a lock-up tycoon by the locksmiths, invented the Karma lock in 2001. In 2002, the invention also invented the idling lock, followed by Lei Xianming is also a big boss developed by the locksmith into the lock industry. He invented the atomic lock in 1999 and invented the idling lock in 2005. Since 2005, Li's and Ray's idling locks have blocked the thief's smashing tools and become a popular patented new product. The first generation of idling locks has achieved great success, and the two have become the strangers in the lock industry.
