Latch bolt reversing structure and door lock
The invention discloses a latch bolt reversing structure which comprises a latch bolt, a connecting rod, a guide device and a lock body. One end of the connecting rod is connected to the latch bolt, and the other end of the connecting rod is slidably connected to the guide device; the connecting rod is rotatably connected to the guide device around the axis of the connecting rod; a groove formed in parallel to the connecting rod is formed in the lock body, and a sliding block is arranged on the guide device; the sliding block is slidably connected to the groove; and a locking mechanism used for preventing the guide device and the lock body from being slide relative to each other is arranged between the guide device and the lock body. The connecting rod is rotatably connected to the guide device around the axis of the connecting rod, and therefore force is applied to rotate the latch bolt and drive the connecting rod to rotate, so that the reversing of the latch bolt can be completed; the lock body does not need to be disassembled, and the guide device and the lock body are prevented from being slide relative to each other through the locking mechanism after the latch bolt is reversed; and the latch bolt is prevented from accidentally stretching out of the lock body when the door lock is normally used.
本发明公开了一种斜舌换向结构，包括斜舌、连接杆、导向装置和锁体；连接杆的一端连接于斜舌，连接杆的另一端可滑动地连接于导向装置，且连接杆绕其轴线转动连接于导向装置；锁体上设有与连接杆平行设置的凹槽，导向装置上设有滑块，滑块可滑动地连接于凹槽；导向装置和锁体之间设有用于阻止导向装置与锁体相对滑动的锁止机构；由于连接杆绕其轴线转动连接于导向装置，因此施力转动斜舌并带动连接杆旋转即可完成斜舌的换向，无需拆卸锁体，对斜舌换向后通过锁止机构阻止导向装置和锁体相对滑动，避免斜舌在门锁正常使用时意外伸出锁体。
