Zipper-type coded lock

Abstract

The invention discloses a zipper-type coded lock and relates to the technical field of locks. The zipper-type coded lock structurally comprises a lock hook buckled with a zipper, a lock block for pressing the lock hook to achieve locking, and further comprises an unlocking mechanism; through arrangement of the lock block adopting an electric sheet structure, before locking, the lock hook is positioned at an unlocked position, and when locking is required, the zipper is held by a hand and is buckled into the lock hook, the lock hook is pressed to extrude the lock block to elastically deform the lock block, at the moment, the lock hook crosses the lock block, then the hand loosens the zipper, the lock block rebounds and presses the lock hook and the lock hook cannot return to the unlocked position, so that locking is achieved. The lock block adopting the electric sheet structure is used for substituting a restoring component in the prior art, and in the locking process, one-handed operation can be achieved, so that a purpose of locking with convenience is achieved.

Description

technical field [0001] The invention relates to the technical field of locks, in particular to a zipper combination lock. Background technique [0002] The zipper coded lock generally can control the movement of the shackle through the unlocking mechanism, and then control the locking or separation of the shackle and the zipper, so as to realize the locking or unlocking of the zipper coded lock. Among them, the unlocking mechanism generally includes a push system, a key lock assembly, a combination wheel lock assembly and a transmission control assembly. The key lock assembly or the combination wheel lock assembly controls the movement of the lock hook through the transmission control assembly. The unlocking of the zipper combination lock can be realized, and the convenience of use and the diversity of operation of the combination lock can be enhanced. [0003] In the existing zipper combination lock, the lock hook is designed to retract and unlock in translation; in order ...

AI Technical Summary

Problems solved by technology

[0004] In order to allow the lock hook to move in parallel, there must be enough space inside the combination lock, which cannot make the volume design of the zipper combination lock more compact

If the translation of the lock hook is changed to rotation in order to save space, after unlocking, it is equivalent to the push of the above-mentioned reset part to make the lock hook rotate and reset to the locked position. At this time, the lock hook is engaged with the lock block and locked when needed At this time, it is necessary to control the push with one hand to control the rotation of the lock hook to separate from the lock block, and make the lock hook rotate to the unlocked position. At this time, the other hand picks up the zipper to buckle it into the lock hook, release the push, and the lock locks The hook rotates to the locked position again, and then realizes the locking. It can be seen that when the rotating lock hook is locked, the coordinated operation of both hands must be used to complete the locking, so that the locking operation of the combination lock is not convenient enough
