Round key lock with variable passwords

Abstract

The invention discloses a round key lock with variable passwords. The round key lock comprises a lock body and a handle capable of being rotatably mounted on the lock body; multiple keys are arranged on the lock body, an internal containing space is defined by the lock body and a cover plate, a rotating shaft, a telescopic block, a variable number block, a fixing base, a reset base and a rotating block are arranged in the containing space, the handle, the rotating shaft and the rotating block are connected to form an integral structure so as to be jointly and rotatably arranged relative to the lock body, the handle stretches out of the outer side of the lock body, the rotating block stretches out of the outer side of the cover plate, the rotating shaft is linked with the telescopic block so as to move along a limiting groove in the lock body, the telescopic block is linked with the variable number block to synchronously rotate, the variable number block is linked with the fixing base to synchronously rotate, and therefore, through the ingenious rotatable linkage relation between special structural design of the lock body, the handle, the keys, the rotating shaft, the variable number block, the fixing base and the rotating block and corresponding parts, the aim of flexibly changing the passwords can be achieved, and the safety anti-theft performance of the lock can be improved.

Description

technical field [0001] The present invention relates to the technical field of push-button locks, in particular to a round-shaped push-button lock with a variable password.
