For the double-reed shielding structure, it is necessary to realize the vertical insertion of the double-reed shielding component and the slotting knife, and for the rotation of the door leaf relative to the door frame, the movement trajectory of the door leaf is a rotating arc movement, so the arc movement of the door leaf here The trajectory has a certain resistance to the trajectory of the vertical insertion of the double-reed shielding assembly and the blade, so that when the door leaf and the door frame are matched with the single-pole double-reed shielding structure, a large force is required to make the double-reed shielding assembly and the blade. Therefore, it is inconvenient to lock and close the whole door leaf relative to the door frame, and it also affects the efficiency of closing.
