The invention relates to an elevator retractable door vane. The center of a door vane crank arm and the center of a door vane straight arm are movably connected to the upper portion and the lower portion of the front face of a door vane bottom plate. The two ends of two door vane blade bottom plates are movably connected to the two ends of the door vane crank arm and the two ends of the door vane straight arm respectively. Vane blade retractable plates are movably connected to the outer side walls of the door vane blade bottom plates. The vane blade retractable plates are hinged to the door vane bottom plates through connecting plates. When the door vane crank arm is rotated, the two door vane blade bottom plates are driven to move, and meanwhile the two vane blade retractable plates will move forwards or backwards along long holes under the drive of the connecting plates, so that while the door vane is tightened left and right, and the left and right vane blade retractable plates move forwards at the same time to clamp a hoistway door ball to open a door; otherwise, while the door vane is opened left and right, the left and right vane blade retractable plates move backwards at the same time and retract for a certain length, and the potential safety hazard that the elevator door vane collides with a hoistway door sill or the door ball due to shaking produced when an elevator car runs at high speed is eliminated.
