When the internal pressure of the experimental area needs to be changed, the cover plate 20 is opened and closed by the lock 40 to make the change.

[0026] Specifically, such as Figure 2 As shown, a controller 50 is provided on the wall 10, and a control shaft 501 extends from the bottom of the controller 50 and passes through the first loose-leaf 301, the second loose-leaf 302 and the third loose-leaf 303 in sequence. A plurality of clamping columns 502 are provided on the control shaft 501. When the pressure in the laboratory needs to be remotely controlled, the control shaft 501 is controlled by operating the controller 50, and the loose-leaf plate 30 is fixed in a specified position by the clamping columns 502 on the control shaft 501 so that the cover 20 is opened and closed to the specified position. A display 503 is provided on the controller 50, and a switch 504 is provided below the display 503 to facilitate the detection of the pressure in the laboratory.

[0027] Specifically, such as Figure 3 As shown, a first groove 101 is provided on the other side of the wall 10, and a fixing ring 60 is provided on the first groove 101.
