Latch bolt anti-insertion and anti-theft structure and door lock with same
The invention belongs to the technical field of mechanical locks, and particularly relates to a latch bolt anti-insertion and anti-theft structure and a door lock with same. The latch bolt anti-insertion and anti-theft structure comprises a latch bolt assembly, a limiting assembly, an unlocking assembly and a locking assembly, the locking assembly has a locking state for limiting a limiting pieceto move to a latch bolt retraction path in a door opening state and a unlocking state that the limiting piece is not restricted to move to the latch bolt retraction path in the door-closing state. According to the latch bolt anti-insertion and anti-theft structure, by arranging the locking assembly, the limiting end of the limiting piece is limited to move to the latch bolt retraction path in thedoor opening state, and the limiting piece is not limited to move to the latch bolt retraction path in the door closing state; that is to say, when the door is opened, the limiting piece cannot move to the latch bolt retraction path, so that the latch bolt is in an unlocked state; when the door is closed, the limiting piece is not limited by the locking assembly and can move to the retraction pathof the latch bolt, the latch bolt is locked, and the effect of anti-insertion and anti-theft opening is achieved; meanwhile, when the door is opened, the latch bolt is unlocked and can retract or extend out of the lock shell.
本发明属于机械锁技术领域，具体涉及一种斜舌防插盗开结构及具有其的门锁，其中斜舌防插盗开结构包括斜舌组件、限位组件、解锁组件及锁定组件，锁定组件具有在开门状态限制所述限位件移动到所述斜舌缩回路径上的锁定状态，和在关门状态不限制所述限位件移动到所述斜舌缩回路径上的解锁状态。通过设置锁定组件，在开门状态时限制限位件的限位端移动到斜舌缩回路径上，在关门状态下不限制限位件移动到斜舌缩回路径上；也就是说在开门时限位件不会移动到斜舌缩回路径上，从而斜舌处于解锁状态；在关门时限位件不受锁定组件的限制，会移动到斜舌缩回路径上，斜舌锁定，起到了防插盗开效果；同时在开门时，斜舌解锁，可以缩回或伸出锁壳。
