The invention discloses a lock body latch bolt reversing structure which comprises a lock body shell, a lock body latch bolt and a lock bolt fixing baffle, a latch bolt hole is formed in the lock body shell, the lock bolt fixing baffle can be installed in the lock body shell in the mode that the lock bolt fixing baffle can axially slide in a reciprocating mode for a set distance along the latch bolt hole, and the lock body latch bolt can be inserted into the latch bolt hole or slide out of the latch bolt hole. When the lock body latch bolt is arranged in the latch bolt hole, the lock body latch bolt can axially slide relative to the latch bolt hole and is stopped in the circumferential direction, an axial limiting structure is arranged on the lock body latch bolt, an operation end is formed on a reversing shifting block installed on the lock bolt fixing baffle, and a hollow reversing window right opposite to the operation end of the reversing shifting block is formed in the door lock shell. After the reversing shifting block moves to a designated position, the lock body latch bolt can be axially positioned on the latch bolt fixing baffle in a locking mode, so that the lock body latch bolt is kept in the latch bolt hole and axially slides to achieve unlocking or locking, the direction of the lock body latch bolt can be easily changed according to the door opening direction, and the door lock is convenient to produce, sell and install.
本发明公开了一种锁体斜舌换向结构，包括锁体外壳、锁体斜舌和锁舌固定挡板，锁体外壳上形成有斜舌孔，锁舌固定挡板能沿斜舌孔轴向往复滑动设定距离的安装于锁体外壳内，锁体斜舌能插设于斜舌孔内或从斜舌孔中滑出，锁体斜舌在斜舌孔内时，锁体斜舌相对于斜舌孔轴向能滑动且圆周方向止动，锁体斜舌上设有轴向限位结构，安装于锁舌固定挡板上的换向拨块上形成有操作端，门锁外壳上形成有与换向拨块的操作端正对的镂空的换向窗口，换向拨块运动到指定位置后能将锁体斜舌轴向止动的定位于斜舌固定挡板上，使得锁体斜舌保持在斜舌孔内轴向滑动实现开锁或闭锁，本发明能够根据开门方向轻松更换锁体斜舌的方向，方便门锁生产、销售和安装。
