Latch bolt structure and door lock
The invention discloses a latch bolt structure which comprises a latch bolt, a connecting rod, a guide device and a lock body. The connecting rod is provided with a head end and a tail end, and slidably connected to the guide device, and the head end of the connecting rod is connected to the latch bolt; the guide device is slidably connected to the lock body, and the relative sliding direction of the guide device and the lock body is parallel to the connecting rod; a mounting hole located in the axis of the connecting rod is formed in the lock body, and a clearance is formed between the latch bolt and the hole wall of the mounting hole; the latch bolt penetrates out and is far away from the mounting hole when the guide device is moved towards the mounting hole; a clearance is formed between the latch bolt and the hole wall of the mounting hole, and the latch bolt can be contained in the mounting hole and can be further completely pulled out of the mounting hole, namely that the latch bolt penetrates out of the mounting hole and is far away from the mounting hole when the guide device is moved towards the mounting hole, thereby facilitating lock installation personnel to maintain or reverse the latch lock; and an existing limiting convex block is omitted in the latch bolt, and therefore, when the latch bolt is reset, noise generated by collision between the limiting convex block and the lock body cannot be avoided.
本发明公开了一种斜舌结构，包括斜舌、连接杆、导向装置和锁体；连接杆具有首端和尾端，连接杆可滑动地连接于导向装置，连接杆的首端连接于斜舌；导向装置可滑动地连接于锁体，且导向装置与锁体的相对滑动方向平行于连接杆；锁体上开设有位于连接杆的轴线的安装孔，斜舌与安装孔的孔壁之间设有空隙，斜舌在导向装置朝安装孔运动时穿出并远离安装孔；斜舌与安装孔的孔壁之间设有空隙，斜舌不仅能够收容于安装孔，还能够从安装孔中完全抽出，即斜舌在导向装置朝安装孔运动时穿出并远离安装孔，以便装锁人员对斜舌进行维修或换向操作，且由于该斜舌省去了现有的限位凸块，因此在斜舌复位时不会产生限位凸块与锁体撞击产生的噪音。
