A self-locking door lock with an electromechanical universal unlocking method

Abstract

The invention relates to an automatically-closed door lock with an electromechanical general unlocking mode. The automatically-closed door lock comprises a main spring bolt, an auxiliary spring bolt, a lining plate, a locking key, a key opening key and a handle. The main spring bolt and the auxiliary spring bolt move on the portion, on one side of a lock body shell, of a lock body face plate. The main spring bolt and the auxiliary spring bolt are fixedly connected with one end of a spring bolt plate. A reset spring is arranged between the other end of the spring bolt plate and the inner side wall of the lock body shell in a clamped mode. The unlocking point of the spring bolt plate makes contact with the opening push point of a shifting fork. The spring bolt plate transversely moves in a guide groove of the lining plate. A locking key torsional spring is arranged in the locking key. Both the locking key and the locking key torsional spring are fixedly connected with the spring bolt plate. The key opening key is fixed to an insertion groove of the shifting fork through a bolt. A lock cylinder is fixed into the key opening key. The handle makes contact with the shifting fork and is sleeved with a handle lining sleeve. The automatically-closed door lock has the advantages that installation is easy, the automatically-closed door lock can be installed and used by everybody, and the automation application range is wider.

Description

technical field [0001] The invention belongs to the technical field of lock bodies, and in particular relates to an automatic locking door lock with an electromechanical universal unlocking method. Background technique [0002] At present, there are many types of lock bodies, but the more common lock bodies are electronically controlled lock bodies and mechanical lock bodies. Due to the insufficient design of the lock bodies, some lock bodies cannot be matched with each other. In use, the versatility is not strong enough, and some lock bodies need to be turned several times before they can be locked. There are troubles in unlocking and locking. It is predicted that the consequences of possible elimination in the future cannot keep up with the trend of the times; When locked, the contact with the door frame is not good, it is easy to generate noise, and sometimes it is affected by the closing gap between the door and the frame, resulting in a little shaking.
