High-safety lock and key

Abstract

A high-security lock and key is to make the key body enter the lock body from the key hole on the idling lock cylinder through the driving groove in contact with the key body, or to drive the key body from the lock body through the contact with the key body. The setting method of driving the groove into the key hole on the idling lock cylinder, so that the hidden pin in contact with the boss or non-boss part on the key body, the end of the non-hidden pin, enters the lock body from the lock cylinder, or Enter the lock cylinder from the lock body to realize the long-distance movement of the hidden pins and the non-hidden pins, and move in the opposite direction, which improves the security capacity of the lock, reduces the mutual opening rate, and makes unlocking more convenient and simple. The drive recess is placed within the lock within the cover of the non-circular key entry to prevent technical and vandalism from opening the lock.

Description

technical field [0001] A high-safety lock and key realize that the pin end in contact with the key can enter the driving groove on the lock body from the key hole on the lock cylinder, or enter the key hole on the lock cylinder from the driving groove on the lock body To improve the security of the lock, the lock belongs to the technical field of locks. Background technique [0002] There are at least three deficiencies in the known locks. The one is that the end of the tumbler in contact with the key on the known lock is in the keyhole, which causes the lock to be easily opened or destructively opened by technology; The end can only move in the same direction, or move in the keyhole, which provides conditions for the unlocking tool to implement technical unlocking. The reason is the design concept of the lock and the structure of the lock. Known keys for unlocking all rely on the non-boss part of the concave key body, that is, the pin groove or the serpentine groove or t...

AI Technical Summary

Problems solved by technology

[0002] There are at least three deficiencies in the known locks. One is that the end of the tumbler that contacts the key on the known lock is in the keyhole, which makes the lock easy to be damaged by technology. Opening or destructive opening; the second is that the pin tip that is known to be in contact with the key can only move in the same direction, or move in the key hole, which provides conditions for the unlocking tool to implement technical unlocking; the third is to drive the hidden pin in the pin hole to move The key is complicated, the unlocking method is complicated, and it is not easy to promote and use
