Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0039] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0040] like Figures 1 to 6 As shown, the present application provides a suction cup structure 100 for front maintenance of a display screen, specifically for removing a display module 200 of a display screen from a box, wherein the display module is divided into a display module with a mask and a display module without a mask. The suction cup structure 100 includes a suction cup body 10 and a sealing gasket 20, and the sealing gasket 20 is detachably connected to the suction cup body 10. The surface of the sealing gasket 20 is serrated or wavy, and the surface of the suction cup body 10 is flat. The suction cup structure 100 is assembled with the sealing gasket 20 for use or disassembled for use. That is, the suction cup structure 100 can be attached to the display module 200 with a mask through the sealing gasket 20, and can also be attached to the display module 200 without a mask by removing the sealing gasket 20, thereby adapting to the disassembly of different types of display modules 200, thereby improving the versatility of the suction cup structure.

[0041] For example, when the suction cup structure 100 is used with the sealing gasket 20 attached, the surface of the sealing gasket 20 adheres to the display module 200 with a mask, enabling the suction cup structure 100 to form a stable suction force with the display module 200 with the mask, thereby allowing the disassembly of this type of display module 200. When the suction cup structure 100 is used without the sealing gasket 20, the surface of the suction cup body 10 adheres to the display module 200 without the mask, that is, the suction cup structure 100 can be directly adsorbed on the light board of the display module 200, thereby allowing the disassembly of this type of display module 200. This not only improves the versatility of the suction cup structure 100, but also simplifies operation.

[0042] In an optional embodiment, the display module 200 includes a display module 200 for being equipped with a mask. The display module 200 equipped with a mask includes a light board and a mask arranged on the outside of the light board. The mask has a brim structure, and the ends of the brim structure are mostly serrated or wavy. The surface of the sealing gasket 20 is uneven. Specifically, the surface of the sealing gasket 20 is serrated, wavy, or stepped. The surface shape of the sealing gasket 20 is adapted to the shape of the brim structure. The present invention is not specifically limited here. The shape of the sealing gasket 20 and the shape of the mask can be adapted to fit and form an air pressure difference between the air pressure between the suction cup structure 100 and the display module and the external air pressure, thereby generating suction to tighten the display module. In addition, the dot pitch of the mask corresponding to different models of display modules 200 is different. Therefore, the sealing gasket 20 of the present application also has multiple models, that is, the serrated, wavy or stepped surface of the sealing gasket 20 can match the masks corresponding to display modules 200 of different models, so that it can adapt to the masks corresponding to display modules 200 with different dot pitches, so that the suction cup structure 100 can replace the sealing gasket 20 corresponding to its mask according to different display modules 200, so that the suction cup structure 100 can be completely fitted with the mask, thereby forming a sealed state, so that the suction cup structure 100 forms a stable suction force on the display module 200, so that the display module 200 can be removed from the box frame.

[0043] In an optional embodiment, the display module 200 includes a display module 200 for use without a mask. The display module 200 without a mask includes a light board, and no mask is installed on the outside of the light board. When the suction cup structure 100 needs to be disassembled and maintained for the display module without a mask, the sealing gasket 20 can be removed from the suction cup structure 100, and the flat surface of the suction cup body can be attached to the display module without a mask, so that the suction cup structure 100 can be directly attached to the light board, thereby enhancing the versatility of the suction cup structure 100. In an optional embodiment, the suction cup body 10 has a handheld portion 12 and a suction end 11 for mating with the display module 200. The suction end 11 is provided with a first assembly portion, and the sealing gasket 20 is provided with a second assembly portion, so that the sealing gasket 20 can be detachably installed in the suction end 11 through the mating of the second assembly part with the first assembly part, thereby solving the problem of installing and removing the sealing gasket 20 and the suction end 11. The handheld portion 12 can detach the display module 200 when the suction cup structure 100 is adsorbed on the display module 200 and forms a suction force for attaching to the display module 200 .

This application does not limit the specific type of magnetic adsorption components or the raw materials used to make them.

[0046] When the sealing gasket 20 is connected to the adsorption end 11, the opposite magnetic poles of the first and second assembly parts face each other, so that the sealing gasket 20 can be firmly fixed to the adsorption end 11 under the attraction of the opposite magnetic poles.

[0051] In addition, the snap portion can also be set on the sealing gasket 20, and the slot portion can also be set on the adsorption end 11. The position of the slot portion corresponds to the position of the snap portion, so that the sealing gasket 20 can be tightly fixed on the adsorption end 11 by the cooperation of the snap portion and the slot portion.
