The invention relates to the technical field of trains, and discloses a vehicle emergency evacuation door lock and a train thereof. The vehicle emergency evacuation door lock comprises a locking mechanism arranged on an evacuation door body and at least two zip-fastener mechanisms, wherein the zip-fastener mechanisms are distributed on one side or two sides of the door body in the height direction, and a vehicle body is provided with fixing columns at the corresponding positions of the zip-fastener mechanisms; each zip-fastener mechanism comprises a lock hook provided with a hook groove matched with the fixing column, the locking mechanism comprises a plurality of pull lines connected with the zip-fastener mechanism in a one-to-one correspondence mode, and the locking mechanism controls the lock hook to rotate by pulling the pull lines to be embedded into or disengaged from the fixing column so as to close or open the evacuation door. A zip-fastener shaft seat is connected with the lock hook through the pull wire, the pull wire drives the lock hook to be disengaged from or hooked into a limiting column by rotating the zip-fastener shaft seat, and rapid opening and closing of the emergency door are achieved. According to the lever principle, a U-shaped handle and a push block are arranged at the position of the locking mechanism, an arc-shaped connecting rod of the U-shaped handle drives the push block to easily achieve rotation of the zip-fastener shaft seat, time and labor are saved, and conditions are further provided for rapid opening and closing of the emergency door.

    本发明涉及列车技术领域,公开一种车辆紧急疏散门门锁及其列车,包括设于疏散门门体上的锁定机构和至少两个拉锁机构,拉锁机构分布在门体高度方向的一侧或两侧,车体在拉锁机构设置的对应位置布置有固定柱,拉锁机构包括开设有与固定柱适配钩槽的锁钩,锁定机构包括多根与拉锁机构一一对应连接的拉线,锁定机构通过拉动拉线控制锁钩旋转来嵌入或脱离固定柱以关闭或开启疏散门。将拉锁轴座与锁钩通过拉线相连,通过旋转拉锁轴座使拉线带动锁钩脱出或钩进限位柱,实现疏散门的快捷开闭;利用杠杆原理,在锁定机构处布置U型手柄和推块,通过U型手柄的弧形连接杆带动推块轻松实现拉锁轴座的旋转,省时省力,进一步为疏散门的快捷开闭提供了条件。
