The invention belongs to the technical field of rail transit equipment, and relates to a baffle type locking mechanism which is fixed in the middle of the lower surface of a cab apron body and clamps a sliding pedal and a positioning pedal together with the cab apron body through a movable baffle, a fixed baffle and the cab apron body, vertical locking of a cab apron assembly is achieved, and the attractiveness of the cab apron assembly cannot be affected. The movable baffle makes sliding contact with the friction piece in the horizontal direction, other mechanisms do not need to be additionally arranged outside, the locking position of the movable baffle is always in the locking state through the automatic reset function of the movable baffle, secondary observation and confirmation are not needed, the false locking phenomenon of the cab apron assembly is avoided, and the locking mechanism cannot be automatically opened; the locking performance of the cab apron assembly is safe and reliable; the buffer head can guarantee the coincidence degree of the movable baffle and the positioning pedal and can also guarantee that the elastic supporting plate is always in a tensioning state, and the situation that when a vehicle moves, the movable baffle is driven to vibrate, and noise is generated is avoided. The structure is reasonable, operation is easy, installation is convenient, the principle is scientific, and the safety of the through channel is guaranteed.

    本发明属于轨道交通设备技术领域,涉及一种挡板式锁闭机构,固定在渡板体下表面的中间,通过活动挡板和固定挡板与渡板体一起夹住滑动踏板和定位踏板,实现渡板组成的垂向锁定,且不会对渡板组成的美观产生影响;活动挡板在水平方向与摩擦件滑动接触,外部无需增加其它机构,活动挡板的自动复位功能,使其锁闭位置始终处于锁闭状态,无需二次观察确认,避免了渡板组成的假锁闭现象的发生,锁闭机构不能自行开启,使得渡板组成的锁闭性能安全可靠;缓冲头既能保证活动挡板与定位踏板的重合程度,又能保证弹性托板始终处于张紧状态,避免车辆运动时带动活动挡板震动产生噪音;其结构合理,操作简单,安装方便,原理科学,保证了贯通道通道的安全性。
