Abstract

The invention relates to the technical field of locks, in particular to a zipper coded lock. The zipper coded lock comprises a lock block assembly used for abutting against a lock hook to achieve locking; the lock block assembly comprises a rotating shaft, two lock block bodies which are arranged in a crossed mode and can rotate around the rotating shaft and an elastic piece driving the two lock block bodies to be folded; and the zipper coded lock further comprises an unlocking mechanism. In the unlocking process, the unlocking mechanism drives the two lock block bodies to be opened so as to release abutting against the lock hook, the lock hook is enabled to rotate, and unlocking is achieved. Locking or unlocking of the lock hook is realized by adopting the two rotatable and crossed lock block bodies, the conventional unlocking mode of horizontal movement of the lock block is replaced by a rotary unlocking mode of the lock block bodies, and the transmission relationship among all partsis optimized, so that the whole transmission process is more compact and smooth, the abrasion of rotary unlocking is smaller, the service life of the zipper coded lock is prolonged, rotary unlockingis more labor-saving than pushing unlocking, and the unlocking is more convenient.

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 combination lock is provided with a keyhole, and a hook for locking the zipper sheet is arranged in the keyhole. The zipper combination lock is also provided with a lock block for resisting the lock hook. The lock block can be translated up and down or left and right. When locking, the lock block is against the lock hook, thereby restricting the lock hook from being able to rotate, thereby realizing the locking of the zipper piece. When unlocking, after the lock block is translated, the lock block releases the locking of the lock hook, so that the lock hook Can be rotated to realize unlocking of the zipper piece.

[0003] This kind of locking block moves horizontally to unlock the structure, the structure is complex, and the degree of wear is large. After a long time of use, it will cause problems such as difficul...
