High-safety lock and key

Abstract

The invention discloses a high-safety lock and a high-safety key. the end of a concealed bead or a non-concealed bead contacted with a lug part of a non-lug part on a key body enters a lock body from a lock tongue or enters the lock tongue from the lock body in the way that the key body enters the lock body from a key hole in a lock tongue which can idle through a driving groove contacted with the key body, or the key body is driven to enter the key hole in the lock tongue which can idle from the driving groove in the lock body in the way of contacting the key body. The long-distance movement and the reverse-direction movement of the concealed bead or the non-concealed bead are realized, the compact capacity of the lock is improved, the mutual unlocking rate is reduced, and the lock is more simple and convenient to unlock.. Technical and damaging unlocking is prevented in the lock baffled by a lock cover, placed in a non-round key inserting opening, of the driving groove.

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 first is that the end of the pin in contact with the key on the known lock is in the keyhole, which makes the lock easy to be opened by technology or destructively. The ends can only move in the same direction, or move in the keyhole, which provides conditions for the unlocking tool to implement technical unlocking. The 3rd, the key that drives the hidden marble in the pinhole to move is complicated, and the unlocking method is complicated, so it is difficult to popularize and use. The reason is the design concept of the lock and the...

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 in contact with the key on the known lock is in the keyhole, which causes the lock to be easily opened by technology or destructively. 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 third is that the key to drive the hidden marbles in the pinholes to move is complicated, and the unlocking method is complicated, which is not easy to popularize and use
