A mechanical lock of double-core mutual control trap-type blade mechanism

Abstract

The invention discloses a mechanical lock of a double-core mutual control trap type blade mechanism, which comprises a lock head body, front and rear lock cores, front and rear locking mechanisms, a gate and a key; the front locking mechanism is a blade mechanism, and the blade mechanism includes a The tumbler and at least one blade for mating with the bottom of the tumbler, the blade is provided with a combination slot and at least one trap slot; the rear lock cylinder is also equipped with a control mechanism for controlling the tumbler, and the rear lock cylinder is not moved in place. Front, the tumbler cannot fall; anti-rear locking mechanism decodes, when the rear lock cylinder moves backward along the axial direction, the tumbler falls, when the tumbler falls into the password slot of the blade, the front locking mechanism decodes, and the gate is closed at the same time, the front , The rear lock cylinder rotates together under the drive of the key to unlock; when the tumbler falls into the trap groove of the blade, the front locking mechanism is not decoded and the blade cannot move. The present invention adopts a new idea and a new method of exchanging position difference for time difference, and is one of the most effective prevention techniques and locksets for violent unlocking 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.
