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.
