The synchronous door vane with the car door lock comprises a door vane bottom plate, a vane arm assembly arranged on the door vane bottom plate and used for opening a landing door, a connecting rod assembly rotationally arranged on the door vane bottom plate and used for driving the vane arm assembly to be opened or closed, and a swing arm assembly rotationally arranged on the door vane bottom plate and used for driving the connecting rod assembly to rotate. The door knife bottom plate is further provided with a lock hook assembly used for locking or unlocking the car door. A rotating point is arranged between the swing arm assembly and the door knife bottom plate, and a pressure spring is arranged between the swing arm assembly and the door knife bottom plate and has pushing force. When the pushing force is located on one side of the rotating point, the pressure spring has the trend of forcing the swing arm assembly to rotate towards one side; when the pushing force is located on the other side of the rotating point, the pressure spring has the trend of forcing the swing arm assembly to rotate towards the other side. The swing arm assembly is kept still through the compression spring when no external force exists, and therefore the effect of reducing the rescue difficulty of the leveling layer when the elevator is powered off is achieved.
本申请涉及一种带轿门锁的同步门刀，其包括门刀底板、设于门刀底板且用于打开层门的刀臂组件、转动设于门刀底板且用于带动刀臂组件张开或闭合的连杆组件、转动设于门刀底板且用于驱动连杆组件转动的摆臂组件，门刀底板还设置有用于对轿门锁定或解锁的锁钩组件；摆臂组件与门刀底板之间具有转动点，摆臂组件与门刀底板之间设置有压簧，压簧具有推动力；当推动力位于转动点一侧时，压簧具有迫使摆臂组件朝其中一侧转动的趋势；当推动力位于转动点另一侧时，压簧具有迫使摆臂组件朝另一侧转动的趋势。本申请通过压簧让摆臂组件在没有外力时保持不动，从而降低电梯停电时平层的救援难度的效果。
