The invention belongs to the technical field of mechanical locks, and particularly relates to a latch bolt mechanism and a door lock with the same. The latch bolt mechanism comprises a mounting frame,a latch bolt and a limiting assembly, the limiting assembly is mounted between the latch bolt and the mounting frame, at the locking position of the latch bolt, the limiting assembly can limit rotation of the latch bolt, the limiting assembly is triggered by unlocking operation to be converted into the releasing state from the limiting state of limiting rotation of the latch bolt, and is triggered by door closing operation to return to the limiting state, at the locking position in the limiting state, the action between a triangular body bevel edge middle of the acting end and the locking hole wall of the door opening side on a door frame is the self-locking relation, the latch bolt cannot move towards the locking direction, the latch bolt mechanism can be opened without twisting a door handle, opening is achieved only through triggering the limiting assembly to be in the releasing state through the unlocking operation, through the door closing operation, the limiting assembly returnsto the limiting state, and operation is more easy and convenient.
本发明属于机械锁技术领域，具体涉及一种斜舌机构及具有其的门锁，其中斜舌机构包括安装架、斜舌和限位组件。限位组件，设置在所述斜舌及所述安装架之间，可在所述斜舌的上锁位置限制所述斜舌的转动；所述限位组件受开锁操作触发从限制所述斜舌转动的限位状态变换为释放状态，由关门操作触发回复到限位状态；在限位状态的上锁位置，所述作用端的三角体斜边中与门框上开门侧的锁孔壁之间的作用为自锁关系，使得所述斜舌不能向锁入方向移动。本发明无需通过扭转门把手来开启斜舌机构，只需通过开锁操作触发限位组件为释放状态实现开启，通过关门操作回复到限位状态，操作更加简便。
