The invention relates to the field of high-speed railway accessories, in particular to a self-locking door lock for a toilet of a high-speed rail way. The self-locking door lock comprises a main lockplate and a secondary lock plate, a motor is connected to the inner wall of one side of the secondary lock plate through bolts, a first gear is connected to the end part of an output shaft of the motor through a key and a key groove, bearings are correspondingly welded to the two sides of the inner wall of the secondary lock plate, a first shaft rod and a second shaft rod are correspondingly and rotatably connected into the two bearings, a second gear is connected to the end part of the first shaft rod through a key and a key groove, a main rotating part is welded to one side of the outer partof the second shaft rod, a connecting paddle is welded to the outer wall of the main rotating part, a third gear is connected to the end part of the second shaft rod through a key and a key groove, and a limiting part is connected to one side of the inner wall, close to the second shaft rod, of the secondary lock plate. According to the self-locking door lock, a pushing paddle pushes a pressing plate, a locking part makes the locking plates push a locking column to clamp and lock, the connecting paddle pulls a pushing plate back, the pushing paddle above a secondary rotating part is pulled back to the main lock plate and the secondary lock plate, the self locking and unlocking are achieved, and using is convenient.
本发明涉及高铁配件领域，具体是一种高铁上卫生间用自锁门锁，包括主锁板与副锁板，副锁板一侧的内壁通过螺栓连接有马达，且马达输出轴的端部通过键与键槽连接有第一齿轮，副锁板内壁的两侧均焊接有轴承，两个轴承的内部分别转动连接有第一轴杆和第二轴杆，第一轴杆的端部通过键与键槽连接有第二齿轮，第二轴杆外部的一侧焊接有主转动件，且主转动件外壁的焊接有连接拨片，第二轴杆的端部通过键与键槽连接有第三齿轮，副锁板靠近第二轴杆的内壁一侧通过螺栓连接有限位件。本发明的推动拨片将压动板推动，锁件使锁板推动锁柱进行卡锁，连接拨片将推动板拉回，副转动件上方的推动拨片拉回到主锁板与副锁板中，实现自锁与开锁，使用便捷。
