Safe-guard door lock with latch bolt capable of being axially locked
The invention discloses a safe-guard door lock with a latch bolt capable of being axially locked. The safe-guard door lock comprises a panel, a housing, a buckle plate, a key, the latch bolt, a latch bolt dragging plate, lock tongue hooks, a twisting device, a stroke and axial limiting device and a security locking device, wherein a latch bolt reed is arranged on the bottom of the latch bolt dragging plate; 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 stroke limiting slot is formed in one side of the latch bolt dragging plate; one end of the limiting block is positioned in the stroke limiting slot; the other end of the limiting block is fitted with the limiting torsion spring; the security locking device comprises a slide block and a stirring 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 latch bolt, and the latch 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.
