Combined anti-theft lock

Abstract

The invention relates to the field of safety antitheft, in particular to a combined anti-theft lock. The combined anti-theft lock comprises a lock body, a main lock body and an auxiliary lock body, wherein the main lock body and the auxiliary lock body are arranged on the lock body. The main lock body comprises a main lock cylinder plate and a lock column. The main lock cylinder plate is fixedly connected with the lock column through a main lock transmission device. When the main lock cylinder plate rotates, the main lock transmission device drives the lock column to stretch out of the lock body. The auxiliary lock body comprises an auxiliary lock cylinder, an auxiliary lock drive device and an auxiliary lock connecting device which are connected in sequence. When the auxiliary lock cylinder rotates, the auxiliary lock drive device drives the auxiliary lock connecting device to move, and when the auxiliary lock connecting device moves to the maximum displacement position, the auxiliary lock connecting device ejects the lock column. The combined anti-theft lock is simple in structure and high in safety, lock opening and closing functions are achieved through the main lock body, secondary locking is carried out after the main lock body is locked through the auxiliary lock body, and therefore the safety of the combined anti-theft lock is improved.

Description

technical field [0001] The invention relates to the field of security and anti-theft, in particular to a composite anti-theft lock. Background technique [0002] At present, there are many locks on the market, including electronic locks and mechanical locks. Electronic locks are easy to be copied, and the security is not high.
