Safe-guard door lock with dead bolt capable of being axially locked
The invention discloses a safe-guard door lock with a dead bolt capable of being axially locked. The safe-guard door lock comprises a panel, a housing, a buckle plate, a key, the dead bolt, a dead bolt dragging plate, lock tongue hooks, a twisting device, a stroke and axial limiting device and a security locking device, wherein a dead bolt strong magnet is arranged in the dead bolt; a locking box magnet is arranged in a lock hole of a locking box; two symmetrical lock tongue hooks are mounted on the latch bolt dragging plate, and a lock tongue is arranged on each lock tongue hook; the stroke and axial limiting device comprises a stroke limiting slot, a limiting block and a limiting torsion spring; the security locking device comprises a slide block which is fixedly connected with the dead bolt dragging plate and a stirring block which is arranged on the bottom of the slide block; and the other end of the slide block is connected with a lock cylinder. After adopting the structure, the safe-guard door lock can limit a radial moving stroke of the dead bolt, and the dead bolt is axially pressed and blocked, so that axial locking capacity is higher, the safe-guard effect is better, back locking can be realized outdoors without the key, and the use is more convenient.
