Double-hook lock
The invention discloses a double-hook lock which comprises a lock body and a door gusset plate. The lock body is fixedly installed on a door body, and the door gusset plate is fixedly installed on a door frame. A spring bolt is fixedly hinged into the lock body. The door gusset plate is provided with a lock hole. The spring bolt is provided with a hooked block which extends outwards and can be fixed to the lock hole in a locked and matched manner through hinged rotation. The spring bolt is further provided with a V-shaped block extending inwards. A lock catch and a connecting rod are arranged in the lock body. The lock catch is fixedly hinged into the lock body through a hinge column and provided with an extending end. The extending end is correspondingly provided with a V-shaped groove which can be matched with the V-shaped block of the spring bolt in an abutting and limiting manner through hinged rotation. When the V-shaped block and the V-shaped groove form abutting and limiting, the hooked block is fixed to the lock hole in the hooked and matched manner. By the adoption of the structure, a user can conveniently unlock the double-hook lock on a door after the spring bolt breaks down and is blocked.
