Abstract

The invention discloses a novel mechanical coded lock which comprises a lock seat, a lock cylinder, at least one coded piece, a longitudinal elastic pressing device, and a code stirring piece. A lock block is arranged on one of the lock seat and the lock cylinder, and a lock groove is formed in the other one of the lock seat and the lock cylinder, wherein the tail portion of the lock block is inserted in the lock groove. The coded piece is rotationally arranged on the lock cylinder, the side wall of the coded piece abuts against the head portion of the lock block in the longitudinal direction, and the elastic pressing device is arranged on the lock cylinder or the lock seat. An unlocking part is arranged on the coded piece, and the coded piece can rotate relative to the lock cylinder so that the unlocking part and the lock block can be aligned to move the lock block away from the lock groove. The code stirring piece is rotationally arranged on the lock cylinder or the lock seat and can transversely move relative to the lock seat. A stirring block is arranged on one of the coded piece and the code stirring piece, a stirring groove matched with the stirring block is formed in the other one of the coded piece and the code stirring piece, and the code stirring piece can rotate till the stirring block and the stirring groove are transversely aligned. The novel mechanism is simple and novel in structure, easy to produce, assemble and use and good in antitheft performance.

Description

technical field [0001] The invention relates to the field of locks, in particular to a combination lock. Background technique [0002] Combination locks do not need to be equipped with unlocking devices such as keys and are easy to use, while mechanical combination locks are very suitable as backup locks because they can be used without electricity. Existing mechanical combination locks usually need to be equipped with a corresponding transmission mechanism for each combination chip to unlock. There are many parts, the structure is more complicated, the processing and assembly are relatively difficult, the cost is high, and the volume is large, which is inconvenient to install. And use, will also affect the appearance of the door. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a new type of mechanical combination lock which is simple in structure and easy to produce, assemble and use. [0004] Th...
