Door lock for passenger car and single sliding plug door
The door lock comprises a spring bolt used for pressing the rear side of a door plate, a transition piece used for pushing the spring bolt to rotate behind the spring bolt, an air cylinder used for driving the transition piece to rotate and an installation base, the transition piece is a lever type transition piece, and the air cylinder is located behind the transition piece and arranged in the width direction of the door plate. A piston rod of the air cylinder makes contact with the rear end of the transition piece, and the transverse-U-shaped installation base is clamped on the upper side and the lower side of the spring bolt, the transition piece and the air cylinder and supports the spring bolt and the transition piece to rotate. The structure of the transition piece is changed into a plane lever type, meanwhile, the position of the air cylinder is changed, the air cylinder is located behind the transition piece, the front end of the spring bolt has a surplus space, the spring bolt can stretch into a narrow gap between a passenger car door plate and a door frame/car body and be buckled into the rear side of the door plate, the door plate restraining capacity is improved, the strip-shaped transition piece is adopted for transmitting air cylinder driving force, and the structure is simple; the cylinder and the lock tongue are located in the same installation space, the overall thickness of the lock is reduced, and installation and debugging are convenient.
本发明公开了一种客车用门锁及单开塞拉门，门锁包括用于按压门板后侧的锁舌，在锁舌后方推动锁舌转动的过渡件、驱动过渡件转动的气缸以及安装座，所述过渡件为杠杆式过渡件，气缸位于过渡件后方，沿门板宽度方向布置，气缸活塞杆与过渡件后端接触，安装座为横U形的安装座，夹持在锁舌、过渡件、气缸上下侧，支撑锁舌和过渡件转动。本发明中，改变过渡件的结构为平面杠杆式，同时改变气缸方位，使气缸位于过渡件后方，锁舌前端便有富余空间，可以伸入客车门板和门框/车体之间的窄缝中，扣入门板后侧，提升门板约束能力，采用条状过渡件传递气缸驱动力，结构简单，易于加工，气缸、锁舌位于同一安装空间，减小锁整体厚度，便于安装调试。
