[0023] It is necessary to point out that the side surface of door board 2 close to the position of door lock can be provided with two rectangular grooves 3 to avoid the interference of sealing strip 5 with door lock, and the two rectangular grooves 3 are symmetrically arranged on the upper and lower sides of door lock.

[0024] Specifically, the power unit includes a transmission shaft 10, a first bevel gear 11, and a second bevel gear 12. A second cavity 13 is formed in the center of the door board 2. The first bevel gear 11 is rotatably installed in the second cavity 13, and a plurality of second bevel gears 12 are meshingly arranged around the first bevel gear 11. The second bevel gears 12 are fixedly connected to the transmission shaft 10 at their shaft centers. Each of the transmission shafts 10 is fixedly connected to a screw rod 7.

[0025] In addition, a hand wheel 14 is installed on the door board 2 to drive the rotation of the first bevel gear 11.

[0026] Specifically, when the door plate 2 is closed, the hand wheel 14 on the door plate 2 is rotated, the hand wheel 14 drives the first bevel gear 11 to rotate, through the meshing with the plurality of second bevel gears 12, the screw rod 7 connected with the plurality of transmission shafts 10 can be driven to rotate synchronously, the screw rod 7 cooperates with the screw sleeve 8, the movable plate 6 in the plurality of first cavities 9 can be driven to move synchronously, and the sealing strips 5 on the four sides of the door plate 2 are synchronously extended outward, the simultaneous sealing of the four sides of the door plate 2 is realized, and vice versa, before the door plate 2 is opened, the hand wheel 14 is only needed to be reversely rotated, so that the four sealing strips 5 are hidden in the rectangular groove 3, when the door plate 2 is rotated, the sealing strip 5 does not generate excessive friction with the door frame 1 and the ground.

[0027] Embodiment 2

[0028] This embodiment is improved on the basis of embodiment 1, and specifically:

[0029] Please refer to Figure 4 and Figure 5 The sealing strip 5 is in an "E" type structure, compared with the common flat rubber strip, the "E" type sealing strip 5 can better adapt to the possible small irregular shape between the door frame 1 and the door body, and has a better effect on preventing air, dust, water vapor and the like from penetrating.

[0030] In addition, after the sealing strip 5 is used for a long time, in order to facilitate the replacement of the aging and damaged sealing strip 5, the side surface of the movable plate 6 is slidably provided with a mounting plate 15, and the sealing strip 5 is mounted on the mounting plate 15 through magic tape and dismounting.
