Problems solved by technology

If one or more of the key teeth on the key do not match the combination of the blades, the grooves on the blades in the lock cylinder will not match the bottom of the tumbler, and the tumbler will not be able to fall, and the tumbler will not be released. The clamping of the lock head body, in this way, the lock cylinder and the lock head body are connected through the tumbler, and the lock cylinder cannot rotate
Although this blade lock of the prior art has better security than the pin lock, it still cannot prevent technical unlocking or violent unlocking.

Abstract

The invention discloses a blade lock with the radial displacement being mutually controlled through a front locking mechanism and a rear locking mechanism. The blade lock comprises a lock body, a lock cylinder, a front brake bolt, a rear brake bolt, a front blade mechanism, a rear blade mechanism, a lock gate and a key. The front brake bolt and the rear brake bolt are arranged side by side between the lock body and the lock cylinder and matched with the front blade mechanism and the rear blade mechanism which are installed inside the lock cylinder to form the front locking mechanism and the rear locking mechanism respectively. The front locking mechanism controls the rear locking mechanism to rotate. The rear locking mechanism controls decoding conditions of the front locking mechanism through a control mechanism. Before the rear brake bolt moves in place, the front locking mechanism does not have the decoding conditions. After the rear locking mechanism is decoded, a spring pushes the rear brake bolt to move downwards in place in the radial direction, the lock gate is closed at the time, control over the front locking mechanism is released by the control mechanism so that the key can decode the front locking mechanism, and unlocking is achieved by rotating the lock cylinder. According to the blade lock, the novel idea and method for replacing time difference with potential difference is adopted, and at present, the blade lock is one of the most effective locks for preventing technological unlocking and violent unlocking in the world.

Description

technical field [0001] The invention relates to a lock, in particular to a radial displacement blade lock with mutual control of front and rear locking mechanisms. Background technique [0002] The blade lock is a kind of lock. The blade lock usually includes a lock body, a lock cylinder, a tumbler, a leaf and a key. The tumbler is arranged between the lock body and the lock cylinder, usually between the lock body and the lock cylinder. With a tumbler slot, the tumbler can only move at the tumbler slot of the lock head body and the tumbler slot of the lock cylinder. When it is not unlocked, the tumbler is at the tumbler slot of the lock head body and the lock cylinder. , so that the lock core can not rotate relative to the lock head body, when unlocking, the tumbler falls, and the lock core at this time can rotate relative to the lock head body to realize unblanking. This kind of blade lock usually has a groove on the upper part of the blade. Through the matching of the key...
