Description

Technical Field

[0001] The utility model belongs to the field of a sealing device, and particularly relates to a special-shaped different-plane sealing structure for a pressure vessel. Background Art

[0002] A sealing strip is a product that seals something to make it not easy to open and plays roles such as shock absorption, waterproofing, sound insulation, heat insulation, dust prevention, and fixation. Sealing strips are made of various materials such as rubber, paper, metal, and plastic. At present, when sealing in the market, all are either fully sealed or sealed on one side. However, when a complex mechanism requires partial sealing, different-plane sealing, or multi-plane simultaneous sealing, this sealing method is not applicable. Content of the Utility Model

[0003] Aiming at the above problems, the purpose of the utility model is to provide a special-shaped different-plane sealing structure that can perform partial sealing, different-plane sealing, and multi-plane simultaneous sealing.

[0004] The utility model is realized through the following technical solutions:

[0005] A special-shaped different-plane sealing structure for a pressure vessel includes a lower cover plate and an upper cover plate on the pressure vessel; the upper cover plate is installed on the lower cover plate; several grooves and protrusions are arranged on the inner side of the lower cover plate; a sealing strip body is further included; the sealing strip body is installed on the surface facing the inner side of the lower cover plate; inward depressions are arranged on the sealing strip body, namely depression one, depression two, and depression three; depression one, depression two, and depression three match the protrusions on the inner side of the lower cover plate, and the connection parts between depression one, depression two, and depression three match the grooves on the inner side of the lower cover plate; the sealing strip body is strip-shaped and has a square cross-section; the sealing strip body is made of a flexible material; depression one, depression two, and depression three are arranged adjacent to each other on three faces of the sealing strip body, and the radian of depression one, depression two, and depression three is 180°.

[0006] Advantages of the Utility Model

[0007] The utility model can perform partial sealing, different-plane sealing, and multi-plane simultaneous sealing, and has a good sealing effect. Description of the Drawings

[0008] The following further describes the utility model in detail with reference to the drawings.

[0009] Figure 1 It is a schematic structural diagram of the utility model.

[0010] Figure 2 It is a schematic working diagram of the utility model.

[0011] As shown in the figure: 1 - sealing strip body; 11 - first recess; 12 - second recess; 13 - third recess; 2 - lower cover plate; 3 - upper cover plate. Specific embodiments

[0012] The following specific embodiments illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0013] It should be noted that the structures, ratios, sizes, etc. shown in the attached drawings of this specification are only used to cooperate with the content disclosed in the specification for those skilled in the art to understand and read, and are not used to limit the limiting conditions under which the present invention can be implemented. Therefore, they do not have any technical essence. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects that the present invention can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in the present invention. At the same time, the terms such as "upper", "lower", "left", "right", "middle", etc. cited in this specification are only for the convenience of description and are not used to limit the scope under which the present invention can be implemented.

[0021] As Figure 2 shown, the inner side of the lower cover plate 2 is irregular, that is, a number of grooves and protrusions are provided on the lower cover plate 2. After the sealing strip body 1 is clamped into the lower cover plate 2, compressed air is injected into the sealing strip body 1 to make its irregular surface expand and closely fit with the inner side of the lower cover plate 2, thereby achieving a sealing effect.

[0022] The protection scope of the present utility model is not limited to the technical solutions disclosed in the specific embodiments. Any modifications, equivalent replacements, improvements, etc. made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
