What is the principle of AB lock? AB lock schematic flow process. The AB lock keys used for decoration are more common and usually have different designs. A locks are mainly used for decoration and B locks are provided for households. They differ in appearance but they can open security doors. The color is also distinguished, in general, the A lock key is yellow or blue, and the B lock key is set to white or black, which is a very convenient design that can be used for decoration and household use at the same time and avoid unnecessary troubles. This article mainly introduces the AB lock key principle.
AB lock, as its name implies, it has AB two keys. It is a kind of lock made up of marbles and other structures. There are also called bar locks and computer locks, as well as partial locks and Bailey locks.
After the renovation is completed, the owner simply inserts the owner's key into the circle, and the decoration key will lose its function. The purpose of this is to allow the owner to replace the lock cylinder after the renovation is completed. (Some will be assigned a C key, and the C key will be used to invalidate the decoration key)
Although the A and B keys have different tooth holes, the only difference is that they do the front end, and the decoration key has one more perforation than the owner's key. In addition, the length and shape of the teeth are exactly the same.
1. The marble structure in the billiard room corresponding to the pits of different depths of A and B keys is special, and a 1mm steel ball is installed between the upper and lower marbles. When using the A key, the height of the lower pin in the billiard room plus the height of the small ball is exactly flush with the lock cylinder, so the lock can be unlocked with the A key; when using the B key, the small ball can just be used. Pushing out the lock core means that the lower bead is flush with the lock core at this time, so the B key can also be twisted to unlock the lock core (this principle is the same as that of the sub-master system). When the lock cylinder rotates a certain angle, The small steel ball will be dropped into the blind hole that was designed in advance on the lock cylinder (this is different from the sub key system) under the action of the upper spring. Some people call this small blind hole as a trap, which is very appropriate. . The diameter of the blind hole is larger than that of the small steel ball, but smaller than the diameter of the marble, otherwise the falling of the marble will cause the lock cylinder to get stuck and cannot be unlocked. Once the small ball falls into the blind hole, it can only rotate with the lock cylinder and it will not run out of the blind hole. It will not affect the use of the B key, but when using the A key, there is no small steel ball, so the next drop in the marble room The marble cannot be flush with the cylinder (the height of the small ball is different) and it cannot be unlocked by turning the cylinder.
2. If the A and B keys are carefully observed, experienced people will find that there are 7 pits in the key. There is a difference between the pits. (General people do not pay much attention, think of two keys, nothing the difference). The deepest pit in a certain position on the A key corresponds to the shallowest pit in this position on the B key, usually the 7th or 1st marble position. Speaking of this, I think the people in the company must have some ideas in mind, so Tongzhou District unlocked reminded the owner of the A key must be taken back after use, and properly preserved or destroyed.
3, manufacturers for people to easily distinguish, 6 B key with a transparent hard shell package, 2 A key to hang out. Some A and B keys have different colors. Two A keys are yellow and six B keys are white. 6 There is an instruction manual on the back of the B key package. The owner must read it clearly before using it. Recognize the use of the two keys and remember not to mix it.
The advantage of the AB key lock is that it can meet the needs of people to decorate their homes, avoiding the loss of the key to open the door when the renovations are in turmoil, or copying the door opening keys for those who have bad intentions, and may avoid the owner's Unsafe factors can also avoid the trouble and cost of changing the lock for safety after renovation.
The above is the science of science and technology of the AB lock principle organized and released by the smart lock China Network. Please pay attention to us for more lock knowledge!
