Description

Technical Field

[0001] The utility model relates to the technical field of airtight doors, in particular to a protective airtight door with a rust removal function. Background Art

[0002] Protective airtight doors are typically installed at the outermost edge of special indoor entrances and exits, serving the dual functions of blocking shock waves and isolating toxic agents. They must be able to block shock waves and meet the appropriate resistance requirements. When selecting a protective airtight door, consider not only the required opening size but also the design pressure requirements. While steel doors are more expensive and offer poor protection against early nuclear radiation, they are often used for relatively large vehicle entrances and exits due to their light weight and flexible opening and closing.

[0003] The paint on the outer side of the existing protective sealed door is easy to fall off after long-term use, causing the sealed door to rust easily, making the plate thinner, reducing the sealing performance, and affecting the appearance. In addition, the existing sealed doors are mostly sealed by rubber gaskets, but the rubber gaskets are affected by their service life after a period of use. The rubber gaskets cannot work very stably in subsequent use, resulting in affected sealing performance. In response to the above problems, the inventors proposed a protective sealed door with rust removal function to solve the above problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a protective closed door with rust removal function, comprising a door frame, a closed door body rotatably connected to the door frame, and a rust removal component rotatably provided on the side of the closed door body;

[0006] The rust removal assembly includes a connecting shell, a rust removal paste and a wire brush plate. The connecting shell is fixedly connected to one side of the closed door body. The inner surface of the connecting shell is fixedly provided with a support tube. The rust removal paste is movably fitted with the inner surface of the support tube. The rust removal paste movably passes through the support tube. A through groove is opened on the side of the connecting shell. A first spring is fixedly provided on the inner surface of the through groove. A slider is fixedly provided on the upper end of the first spring. The slider slides and fits with the inner surface of the through groove. A connecting frame is detachably provided on the side of the slider. A bolt is threadedly inserted into the side of the connecting frame. The end of the bolt is threadedly inserted into the interior of the slider. Four first springs are provided, and the first springs are symmetrically arranged between the through groove and the slider. An extrusion block is fixedly provided on the lower surface of the connecting frame, and the extrusion block is in movably contact with the rust removal paste. A placement plate is fixedly provided on one side of the closed door body, and the wire brush plate is in movably contact with the placement plate. The cross-sectional shape of the placement plate is "concave", and a square groove is provided on the lower surface of the placement plate. A second spring is fixedly provided on the inner surface of the square groove, and a slide is fixedly provided on the other end of the second spring. A limit plate is fixedly provided on the side of the slide away from the second spring, and the limit plate movably passes through the inner surface of the placement plate.

[0022] The rust removal assembly 3 includes a connecting shell 31, a rust removal paste 33 and a wire brush plate 381. The connecting shell 31 is fixedly connected to one side of the closed door body 2. A support cylinder 32 is fixed on the inner surface of the connecting shell 31. The rust removal paste 33 is movably fitted with the inner surface of the support cylinder 32. The rust removal paste 33 movably penetrates the support cylinder 32. A through groove 34 is opened on the side of the connecting shell 31. A first spring 341 is fixed on the inner surface of the through groove 34. A slider 35 is fixed on the upper end of the first spring 341. The slider 35 and the inner surface of the through groove 34 are fixed. Sliding fit, the side of the slider 35 is detachably provided with a connecting frame 36, the lower surface of the connecting frame 36 is fixed with an extrusion block 37, the extrusion block 37 is in active contact with the rust removal paste 33, and a placement plate 38 is fixed on one side of the closed door body 2. The wire brush plate 381 is in active contact with the placement plate 38. A square groove 39 is provided on the lower surface of the placement plate 38. The inner surface of the square groove 39 is fixed with a second spring 391. The other end of the second spring 391 is fixed with a slide plate 4. The second spring 391 is provided with two, and the second spring The 391 is symmetrically arranged between the inner surface of the square groove 39 and the slide plate 4 to improve the stability of the connection. A limit plate 42 is fixed on the side of the slide plate 4 away from the second spring 391. The limit plate 42 is movable through the inner surface of the placement plate 38. The limit plate 42 is movably fitted with the wire brush plate 381. The cross-sectional shape of the placement plate 38 is "concave" for easy connection. The upper sealing cap on the rust removal paste 33 can be rotated to separate it from the rust removal paste 33. Then, the extrusion block 37 can be moved downward to align with the rust removal paste 33 by pressing the connecting frame 36 downward. The rust paste 33 comes into contact with each other, the first spring 341 is compressed, and the rust removal paste 33 is affected by the extrusion force, so that the paste inside the rust removal paste 33 is separated from the inside and falls on the wire brush plate 381. The slider 4 can be driven to move by pulling the protrusion 41, and the limiting plate 42 enters the square groove 39, releasing the limit of the wire brush plate 381. The wire brush plate 381 is repeatedly rubbed against the rusted area, so that the rust removal paste reacts chemically on the surface of the rusted area, and then the rusted area is wiped with a clean wet cloth, and the rust can be easily cleaned;

[0023] A sealing connection groove 5 is provided on the inner surface of the door frame 1, and a sealing gasket 52 is installed in the sealing connection groove 5. A connecting block 53 is fixed to the outer surface of the sealing gasket 52.

[0028] A protrusion 41 is fixedly provided on the lower surface of the slide plate 4 .

[0029] By adopting the above technical solution, the slide plate 4 can be easily moved.

[0030] Working principle: When the utility model is in use, the upper sealing cap on the rust removal paste 33 can be rotated to separate it from the rust removal paste 33, and then the squeezing block 37 can be moved downward to contact the rust removal paste 33 by pressing the connecting frame 36 downward. The first spring 341 is compressed, and the rust removal paste 33 is affected by the squeezing force and the paste inside is separated from the inside and falls on the wire brush plate 381. The slider 4 can be driven to move by pulling the protrusion 41, and the limiting plate 42 enters the square groove 39 to release the limit of the wire brush plate 381. The wire brush plate 381 is rubbed repeatedly against the rusted area so that the rust removal paste reacts chemically on the surface of the rusted area, and then the rusted area is wiped with a clean wet cloth, and the rust can be easily removed. When the closed door body 2 is closed, the closed door body 2 is compressed after contacting the sealing gasket 52, thereby blocking the gap between the closed door body 2 and the door frame 1. After the sealing gasket 52 has been used for a period of time, it can be disengaged from the door frame 1 by rotating the screw 54, and then a new sealing gasket 52 with a connecting block 53 can be replaced, thereby improving the sealing performance.
