A sealing gasket 5 is fixedly installed on the outer walls of the two connecting plates 4. Telescopic openings cooperating with the two sealing gaskets 5 on the same side are provided on the outer walls of both sides of the door panel 2. A rotating chamber and two moving chambers are provided inside the door panel 2. A rotating shaft 6 is rotatably installed inside the rotating chamber. A rocker 7 is fixedly installed on the outer wall of the rotating shaft 6. A driving bevel gear 8 is fixedly installed on the end of the rotating shaft 6. Screws 9 are rotatably installed inside the two moving chambers. The outer walls of the two screws 9 are connected to the driving bevel gear 8 through a rotating mechanism. The rotating mechanism comprises a driven bevel gear 10 fixedly installed on the outer wall of the screw 9. The driven bevel gear 10 is vertically meshed with the driving bevel gear 8.

[0024] The outer walls of the two screw rods 9 are threadedly installed with a movable plate 12 through a limiting mechanism. The limiting mechanism includes a limiting rod 11 fixedly installed inside the movable cavity. The limiting rod 11 slides through the movable plate 12. The limiting rod 11 can limit the movable plate 12 so that the movable plate 12 can only move axially along the outer wall of the screw rod 9. The outer walls of the two movable plates 12 are fixedly installed with a latch 13. The upper and lower ends of the door panel 2 are provided with movable holes that cooperate with the latch 13. The inner wall of the door frame 1 is provided with two jacks that cooperate with the latch 13. The inner wall of the door panel 2 is provided with an installation opening, and a leak plate 14 is fixedly installed on the inner wall of the installation opening. The inner wall of the door panel 2 is fixedly installed with a connecting frame 15 that cooperates with the installation opening, and an air filter element 16 is slidably installed inside the connecting frame 15.

[0025] The inner walls on both sides of the connecting frame 15 are slidably penetrated with fixing pins 17, and the outer walls on both sides of the air filter 16 are provided with fixing holes that cooperate with the fixing pins 17.
