Abstract

The utility model discloses a double-insurance lock, comprising a lock body and a remote-control lock part, wherein the lock body is provided with a handle closing door part, a movable door bolt part and a linkage fork, and the remote-control lock part consists of a remote controller, a battery, an induction switch and an electromagnetic locking part. The battery, the induction switch and the electromagnetic locking part are arranged on the lock body, and the electromagnetic locking part is arranged in the position matched with a door locking bolt plate in the handle closing door part. As the remote-control lock part and a lock core are adopted simultaneously, the double control of the lock can be realized, and the lock has the double-insurance function. After a door is locked by the remote-control lock of the double-insurance lock, even if the lock core can be opened, but the electromagnetic locking part in the remote-control lock part still locks the lock, the door can be opened only after the remote-control lock and the lock core are opened simultaneously. Thus, the problem that a thief technically opens the lock core by an unlocking tool to burglary can be thoroughly solved, and the anti-theft performance of the lock can be greatly enhanced.
