Door frame locking device
The invention discloses a door frame locking device. A locking part on the edge of the lower portion of a door body is connected with a swing arm installed on a door lock on the edge of the upper portion of the door body through a link mechanism. When the door frame locking device works, a lock cylinder can be driven to rotate by rotating a matched key, and accordingly a lock tongue on the lock cylinder and the swing arm are driven to swing. When the lock tongue swings towards a locking station to be in place, the lock tongue enables the upper portion of the lock body to be locked on a door frame, the swing arm synchronously drives the locking part to swing downwards, a locking portion of the locking part swings downwards and is inserted in a lockhole of a limiting base, the lower portion of the door body is located on a frame body, and accordingly the locking operation of the door body is achieved. When the door body needs opening, the key rotates reversely. The door frame locking device can greatly reduce key breakage probability and noise. In addition, the lock tongue and the locking portion can be set to be very short, the corresponding strength is high, the door frame locking device does not bend or deform easily, and the door body can be closed better.
