The top of the outer frame 3 is fixedly connected to a positioning plate 19, and a groove 20 is provided in the middle of the bottom end of the positioning plate 19. The groove 20 It is slidably connected to the top of the door panel 7 so that the door panel 7 can be opened and closed smoothly while maintaining the stability of its position. The top of the outer wall of the door panel 7 is connected to a sealing frame 16, and an observation window 17 is fixedly connected to the inner side of the sealing frame 16. The observation window 17 can ensure the sealing while conveniently observing the objects or conditions inside the door panel 7. The sealing frame 16 can effectively seal the gap of the door panel 7 to prevent dust, insects, etc. from entering the door panel 7 to keep the interior clean and hygienic. At the same time, the sealing frame 16 can also reduce noise and improve the sound insulation effect of the door panel 7.

[0036] Working principle: Before using the device, first install the inner frame 1 on the wall where it is to be installed, and then fix it to the outer frame 3 through the mounting block 4 on its outer side, so as to avoid the mounting block 4 and the mounting hole being exposed, which reduces the aesthetics, and the door panel 7 can be driven to move left and right through the slide groove 6. The moving door panel 7 can insert the card slot plate 13 on it into the left wall of the outer frame 3, and then the card slot plate 13 will push the card block 10 to move downward through its slope shape when moving, and compress the spring 9 at the same time. When the door panel 7 and the card slot plate 13 are completely closed, the spring 9 can release the elastic potential energy to engage the card block 10 on it with the card slot of the card slot plate 13, so as to avoid the mounting hole being exposed. The exposure affects the appearance and can automatically lock the door when the door panel 7 is closed, thereby improving the practicality of the device, and when the door panel 7 is moved, the gear 203 can be driven to rotate through the tooth groove 205 thereon, and the rotating gear 203 can drive the rotating rod 201 to rotate along the outer frame 3, and when the outer frame 3 rotates, the torsion spring 202 thereon can be tightened. Therefore, when the door panel 7 is opened and closed, the torsion spring 202 will be tightened, and the tightened torsion spring 202 can drive the rotating rod 201 and the gear 203 to rotate by releasing the torque, which can automatically close the door panel 7, avoiding people forgetting to close the door when entering and leaving the clean room, resulting in reduced sealing in the clean room, thereby improving the reliability of the device.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
