Abstract

The invention relates to a cam lock. The cam lock comprises a lock body, a lock cylinder, a lock shaft and a lock tongue, wherein the lock body is internally provided with a containing cavity with openings at the two ends; the lock cylinder is arranged in the containing cavity and provided with a spiral groove; the spiral groove is provided with a convex part; the lock shaft is provided with a pinhole; the lock shaft is sleeved with the lock cylinder; a lock pin penetrates through the spiral groove and the pin hole to connect the lock cylinder with the lock shaft in a matched mode; the lock shaft is further provided with a threaded hole; the lock tongue is provided with a through hole; and a bolt penetrates through the through hole to be connected with the threaded hole of the lock shaft.According to the cam lock provided by the invention, the lock cylinder is provided with the spiral groove, and the spiral groove is provided with the convex part; and the phenomenon that the lock isautomatically opened due to shock generated after the lock is closed can be effectively prevented.

Description

technical field [0001] The invention relates to the field of locks, in particular to a rotary cam lock. Background technique [0002] Cam lock, or cam lock, is a lock that controls the rotation of the lock nail through the internal structure. According to the structure of the lock nail, it can be divided into plum blossom lock, triangular cam lock, double-sided pin tumbler lock, etc. The working principle of the rotary cam lock is to rotate the key to drive the lock cylinder and the lock shaft to rotate, and then drive the lock tongue to rotate, so as to realize the opening and closing of the door lock. In some cases where vibration may occur, it is easy to loosen and automatically open. Contents of the invention [0003] The object of the present invention is to provide a rotary cam lock which can effectively avoid the phenomenon of automatic opening due to vibration after the door lock is closed. [0004] To achieve the above object, the present invention proposes a ro...
