[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0035] Reference Figures 1-3 An ultra-thin inflatable sealing door includes a pair of matching door frames 1 and airtight pads 2 fixedly mounted on opposite sides of the two door frames 1. A rubber pad is installed on the inner side of the door frame 1, perfectly fitting the airtight pad 2 to ensure installation accuracy while enhancing overall sealing. The edges of the door frame 1 can be rounded to prevent bumps and damage, improving safety. The airtight pad 2 is provided with an air pipe hole 21, a power cord hole 22, and a signal wire hole 23. The power cord hole 22 is electrically connected to a cable 24, the other end of which is electrically connected to a control box 25. The control box 25 has a built-in intelligent pressure sensor that can monitor pressure changes inside the airtight pad 2 in real time and is connected to an external control system via the signal wire hole 23. The external control system controls the gas to be injected through the air pipe hole 21; this is an existing mature technology and will not be described in detail here. A door panel 3 is embedded in and rotatably mounted on the door frame 1. A viewing window 5 is installed on the door panel 3. The door panel 3 also includes…

[0036] The disassembly and assembly components are located on the door panel 3. These components allow operators to quickly disassemble and assemble the viewing window 5 for cleaning.

[0037] The door frame 1 and the door panel 3 are fixedly connected by the same hinge 26 to facilitate the rotation of the door panel 3. A pressure relief valve 27 for depressurizing the airtight pad 2 is fixedly installed on the door frame 1.

[0038] An air duct hole 28 is fixedly installed through-type on both the airtight mat 2 and the door frame 1, and an air duct hole 29, which is also fixedly installed through-type on the door panel 3, is installed through-type on the airtight mat 2. It should be noted that a flexible hose is installed between the air duct hole 29 and the airtight mat 2 to facilitate communication between the two without obstructing the rotation of the door panel 3. The installation of air duct holes 28 and 29 increases the operator's choice of air inlet.

[0039] Reference Figures 2-3 The assembly and disassembly components include: a fixed frame 4, a limiting seat 41, a T-block 42, a connecting plate 43, an L-shaped rod 44, an assembly and disassembly block 45, and fastening bolts 46.

[0040] The fixed frame 4 is fixedly connected to the vertical side wall of the door frame 1, and the fixed frame 4 and the viewing window 5 are correspondingly set; the pair of limiting seats 41 are fixedly connected to the vertical side wall of the fixed frame 4; the T-shaped block 42 and the limiting seat 41 are horizontally slidably inserted; the connecting plate 43 is fixedly connected to the opposite side wall of the two T-shaped blocks 42; the L-shaped rod 44 is fixedly connected to the connecting plate 43; the disassembly block 45 is fixedly connected to the viewing window 5 and one end of the L-shaped rod 44 respectively; the same fastening bolt 46 and the two disassembly blocks 45 are threadedly connected.

[0041] It should be noted that since dust and impurities are easily attached to the side wall of the viewing window 5 near the airtight pad 2, the viewing window 5 needs to be cleaned for subsequent observation and use. First, pull the pull plate 48 upward, which will drive the rectangular insert rod 47 to pull the spring 49 away from the T-block 42. Then, slide the T-block 42 horizontally so that it moves along the T-shaped slide groove 6 of the limit seat 41, which will drive the connecting plate 43 and the L-shaped rod 44 to move horizontally. After the viewing window 5 is separated from the door panel 3, unscrew the fastening bolt 46, and the disassembly block 45 and the viewing window 5 can be removed for cleaning.

[0042] Reference Figure 3 The assembly and disassembly components also include: a rectangular insert 47, a pull plate 48, and a spring 49.

[0043] A rectangular insert rod 47 is vertically slidably inserted into two limiting seats 41; a pull plate 48 is fixedly connected to the top of the rectangular insert rod 47; a spring 49 is sleeved on the rectangular insert rod 47, and both ends of the spring 49 are fixedly connected to the pull plate 48 and one of the limiting seats 41, respectively. T-shaped grooves 6 are provided on the opposite sidewalls of the two limiting seats 41 to facilitate the horizontal sliding insertion of the T-shaped block 42.

[0044] It should be noted that the rectangular shape of the rectangular insert 47 is designed to prevent it from rotating on its own and affecting its fixation of the connecting plate 43 after it is inserted into the limiting seat 41. When the rectangular insert 47 contacts the connecting plate 43, it blocks the connecting plate 43 within the T-shaped groove 6, thereby locking the connecting plate 43.

[0045] The functional principle of this utility model can be explained through the following operation methods:

[0046] First, the door frame 1 is fixedly installed and connected to the air source through air pipe hole 1 21 and air pipe hole 28. The power cord hole 22 is connected to the cable 24, which connects to the control box 25. When the door panel 3 is closed, the hinge 26 drives the door panel 3 to rotate and fit against the door frame 1. At this time, the control box 25 starts the external inflation system, and the gas enters the airtight gasket 2 through air pipe hole 3 29, causing it to expand and seal the door gap. During use, the internal situation can be observed through the viewing window 5. If pressure relief is required, the pressure relief valve 27 on the door frame 1 is opened to release the air pressure in the airtight gasket 2 so that the door can be opened.

[0047] When the viewing window 5 needs to be cleaned, first pull the pull plate 48 upwards, which will cause the rectangular insert rod 47 to pull the spring 49 away from the T-block 42. Then slide the T-block 42 horizontally so that it moves along the T-shaped slide groove 6 of the limit seat 41, which will cause the connecting plate 43 and the L-shaped rod 44 to move horizontally. After the viewing window 5 is separated from the door panel 3, unscrew the fastening bolt 46, and the disassembly block 45 and the viewing window 5 can be removed for cleaning.

[0048] During installation, the operation is reversed: Align the viewing window 5 with the L-shaped rod 44 via the disassembly block 45, tighten the fastening bolt 46, push the T-shaped block 42 into the limit seat 41, loosen the pull plate 48, and the rectangular insertion rod 47 is inserted into the T-shaped block 42 under the action of the spring 49 to complete the locking.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
