Mechanical lock with twin-core mutual control trap-type blade mechanism

Abstract

The invention discloses a mechanical lock with a twin-core mutual control trap-type blade mechanism. The mechanical lock comprises a lock head body, a front lock cylinder, a rear lock cylinder, a front locking mechanism, a rear locking mechanism, a lock gate and a key; the front locking mechanism is the blade mechanism which comprises a stopper and at least one blade, the blade is used for being matched with the bottom of the stopper, and the blade is provided with a code groove and at least one trap groove; the rear lock cylinder is further provided with a control mechanism used for controlling the stopper, and the stopper cannot drop down until the rear lock cylinder moves in place; on the contrary, the rear locking mechanism is decoded, and when the rear lock cylinder moves backwards in place in the axial direction, the stopper drops down; when the stopper drops into the code groove of the blade, the front locking mechanism is decoded, meanwhile, the lock gate is closed, and the front lock cylinder and the rear lock cylinder are driven by the key to rotate together to open the lock; when the stopper drops into the trap groove of the blade, the front locking mechanism is not decoded and the blade cannot move. According to the mechanical lock with the twin-core mutual control trap-type blade mechanism, a new idea and a new method of replacing position differences by time differences are adopted, the mechanical lock is one of the most effective locksets which can prevent unlocking technically and violently in the world at present.

Description

technical field [0001] The invention relates to a lock, in particular to a mechanical lock with a dual-core mutual control trap-type blade mechanism. Background technique [0002] A kind of lockset of prior art is to adopt leaf mechanism as locking mechanism, and this lockset usually comprises lock head body, lock core, tumbler, blade and key, and tumbler is arranged between lock head body and lock cylinder, usually Both the lock head body and the lock cylinder are provided with tumbler grooves, the tumblers can only move at the tumbler grooves of the lock head body and the lock cylinder, and when not unlocked, the tumblers are at the tumbler grooves of the lock head body Groove and the tumbler groove place of lock core, lock core can not be rotated relative to the lock head body, when unlocking, tumbler falls, and the lock core of this moment just can realize unblanking with respect to the lock head body rotation. The upper part of the blade of this lock is usually provide...

AI Technical Summary

Problems solved by technology

If one or more of the key grooves 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, the tumbler will not fall completely, 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 be rotated

Although this lock of the prior art has better safety compared with the tumbler lock, it still cannot prevent technical unlocking or violent unlocking.
