The invention discloses a pure mechanical pneumatic elevator door capable of preventing people from being clamped. The pure mechanical pneumatic elevator door comprises a door frame and sliding doors,wherein a sliding cavity is formed in the door frame; the two sliding doors which are symmetrical in position and shape are connected to the interior of the sliding cavity in a sliding mode; door closing air cylinders are fixedly connected to the positions, which is close to the upper sides, in the sliding doors; the ends, which face the axis of symmetry, of the door closing air cylinders are closed, and the other ends of the door closing air cylinders are open; first sealing rings are fixedly connected to the positions, which make contact with the inner walls of the door closing air cylinders, of the door closing flap heads; and door closing pistons are fixedly connected to the ends, which are away from the axis of symmetry, of the door closing flap heads, and the other ends of the doorclosing pistons extend into the sliding cavity and are fixedly connected to the cavity wall of the sliding cavity. The door is opened and closed in a pneumatic mode, and the door is closed through a set of locking mechanism, so that the door closing action can be prevented from stopping by collision, and the driving process of closing or opening the door is stopped only when the door is opened completely or is closed completely.

    本发明公开了一种防夹人的纯机械气动式电梯门,包括门框和滑动门,所述门框中设有滑动腔,所述滑动腔中滑动连接有两个位置形状均对称的滑动门,所述滑动门中位于偏上侧位置固定连接有关门气缸,所述关门气缸向对称轴一端封闭另一端开口,所述关门气缸中滑动连接有关门拍头,所述关门拍头在与所述关门气缸内壁接触部分固定连接有第一密封圈,所述关门拍头远离对称轴一端固定连接有关门活塞且所述关门活塞另一端伸出至滑动腔中并固定连接在所述滑动腔的腔壁上,通过气动的方式来实现开门和关门,关门是有一套锁定机构,可以防止由于碰撞而导致关门动作终止,关门或者开门的驱动过程只有在开完全或者关闭完全才停止。
