DETAILED DESCRIPTION OF EMBODIMENTS

[0015] In order to further understand the features, technical means, and specific objects and functions achieved by the present utility model, the present utility model is described in further detail below with reference to the accompanying drawings and specific embodiments.

[0016] Reference is made to FIGS. 1 and 2.

[0017] An embodiment of the present utility model discloses a sealed cleanroom door structure, comprising an inner door panel (10) and an outer door panel (20) that are fixedly connected. The inner door panel (10) and the outer door panel (20) are connected by welding. The panel surfaces of the inner door panel (10) and the outer door panel (20) are opposed and in close contact to form a joint surface. The line connecting the center of the inner door panel (10) and the center of the outer door panel (20) is perpendicular to the joint surface, i.e., the center positions of the inner door panel (10) and the outer door panel (20) correspond to each other. The length and width of the inner door panel (10) are a and b respectively, and the length and width of the outer door panel (20) are A and B respectively, where a<A and b<B. The shapes of the inner door panel (10) and the outer door panel (20) correspond and match; their lengths extend in the same direction, and their widths also extend in the same direction. The panel surface area of the outer door panel (20) is greater than the panel surface area of the inner door panel (10), and the outer door panel (20) protrudes beyond an end surface of the inner door panel (10). The end surfaces of the inner door panel (10) and the outer door panel (20) form a stepped structure, and a cross section of the door structure formed between the inner door panel (10) and the outer door panel (20) has a convex profile. The inner door panel (10) is provided with an inner window opening (11), and the outer door panel (20) is provided with an outer window opening (21). The line connecting the centers of the inner window opening (11) and the outer window opening (21) defines a window-opening axis, and the window-opening axis is perpendicular to the joint surface, i.e., the center positions of the inner window opening (11) and the outer window opening (21) correspond to each other. The length and width of the inner window opening (11) are h and i respectively, and the length and width of the outer window opening (21) are H and I respectively, where h>H and i>I, i.e., the area of the inner window opening (11) is greater than the area of the outer window opening (21), which can effectively ensure the sealing performance between the glass plate and the outer door panel (20).

[0018] When installing the glass plate, a glass plate having a shape and size matching those of the inner window opening (11) is used, and the glass plate and the outer door panel (20) are connected by a material such as glass cement. The area of the glass plate is greater than the area of the outer window opening (21), and the outer door panel (20) can effectively limit the position of the glass plate and provide a seal thereat, which can effectively improve the sealing performance of the overall cleanroom door structure. When opening and closing the cleanroom door body, the stepped structure at the edge of the cleanroom door body can effectively fasten with the door frame, and the gap between the door frame and the cleanroom door body is a bent, non-linear structure, which can effectively improve the sealing performance between the cleanroom door body and the door frame, thereby effectively preventing contaminants such as bacteria and dust from passing from one side of the cleanroom door body and the door frame to the other side.

[0019] In the present utility model, the end surface of the door body is configured as a stepped structure, which can ensure that a non-linear bent seam structure is formed between the door body and the door frame, can effectively block contaminants such as bacteria and dust from passing through, has good sealing performance, and can prevent the purification effect in the limited space from being affected. In addition, a window-opening structure in which a glass plate can be embedded is provided on the door body, so that the door body has an observation function; and the inner wall of the window-opening structure is stepped, which can effectively prevent contaminants from passing through the window-opening structure.

[0020] In this embodiment, the inner door panel (10) and the outer door panel (20) are both hollow panels. The hollow panel structure can effectively save material and, at the same time, reduce the load on the connecting structure when opening and closing the door, which can effectively prolong the service life.

[0021] In this embodiment, the thickness of the outer door panel (20) is D, and as shown in FIG. 1, the thickness of the inner door panel (10) is d, where D>d. A lock body (30) is disposed in the outer door panel (20), a handle (31) is connected to each of two sides of the lock body (30), and the two handles (31) protrude from the surface of the inner door panel (10) and the surface of the outer door panel (20), respectively. An inner frame of the door frame has a stepped structure cooperating with the end surface of the cleanroom door body. The locking force acts mainly on the outer door panel (20), and the gap between the door frame and the cleanroom door body is zigzag-shaped, which can effectively block contaminants from passing through.

[0022] In this embodiment, the thickness of the outer door panel (20) is D, and as shown in FIG. 2, the thickness of the inner door panel (10) is d, where D<d. A lock body (30) is disposed in the inner door panel (10), a handle (31) is connected to each of two sides of the lock body (30), and the two handles (31) protrude from the surface of the inner door panel (10) and the surface of the outer door panel (20), respectively. The door frame may have a structure in which the cross section of a frame strip is rectangular. The locking force acts mainly on the inner door panel (10), and the gap between the door frame and the cleanroom door body is L-shaped, which can effectively block contaminants from passing through.

[0023] In this embodiment, a sealing rubber frame (40) is fitted over the exterior of the inner door panel (10). Preferably, the sealing rubber frame (40) is a rubber frame, which can further improve the sealing performance between the cleanroom door body and the door frame.

[0024] Based on the above embodiments, the sealing rubber frame (40) is a thin-sheet frame, and the sealing rubber frame (40) is in close contact with the surface of the outer door panel (20) adjacent to the inner door panel (10), i.e., the surface of the sealing rubber frame (40) is attached to the surface of the outer door panel (20). When the door body is pushed outward for installation, this can effectively prevent the sealing rubber frame (40) from obstructing the opening and closing of the door, while ensuring the sealing performance.

[0025] The above embodiments only describe several embodiments of the present utility model, and the description thereof is relatively specific and detailed. However, this should not be construed as a limitation on the patent scope of the present utility model. It should be noted that, for a person of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can be made, all of which fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be defined by the appended claims.
