DETAILED DESCRIPTION

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1: As Figures 1-7 As shown, the present invention provides a display screen cover structure made of colorless transparent polyimide, including a transparent polyimide display screen body 1, a limiting frame 2 fixedly installed on the outer surface of the transparent polyimide display screen body 1, an operation button 3 provided on the outer surface of the transparent polyimide display screen body 1, a cover frame 4 provided on the transparent polyimide display screen body 1, a positioning seat 5 fixedly installed at the other end of the cover frame 4 away from the transparent polyimide display screen body 1, a slot 7 opened on the inner surface of the cover frame 4, a transparent cover plate 8 provided on the inner surface of the cover frame 4, a limiting block 9 fixedly installed at the end of the transparent cover plate 8 near the transparent polyimide display screen body 1, and a sealing gasket 10 fixedly installed on the inner surface of the cover frame 4.

[0032] Specifically, a limiting groove 12 is formed on the inner surface of the cover frame 4, and a protective sleeve 13 is fixedly installed on the inner surface of the limiting groove 12. The limiting groove 12 is adapted to the limiting frame 2. The advantage is that when installing the cover frame 4, the limiting frame 2 of the transparent polyimide display body 1 is first aligned with the limiting groove 12 of the cover frame 4, and then the transparent polyimide display body 1 is slowly pushed into the limiting groove 12 until the four corners of the transparent polyimide display body 1 are in close contact with the protective sleeve 13. This can accurately position the transparent polyimide display body 1 in the cover frame 4 and prevent the display from shifting or shaking in the horizontal direction.

[0033] Specifically, the four corners of the transparent polyimide display screen body 1 are in contact with the protective sleeve 13. The protective sleeve 13 is a rubber protective sleeve. The advantage is that the rubber protective sleeve 13 can not only provide cushioning at the contact points between the transparent polyimide display screen body 1 and the cover frame 4, reducing damage to the display screen caused by external impact or collision during assembly, protecting the corners of the display screen, and extending the service life of the display screen, but also fill tiny gaps, playing a sealing and dustproof role.

[0034] Specifically, the card slot 7 is in the shape of an inverted "Z", and the limiting block 9 is inserted into the card slot 7. When installing the transparent cover plate 8, first align the limiting block 9 at one end of the transparent cover plate 8 with the opening end of the inverted "Z"-shaped card slot 7 on the inner surface of the cover plate frame 4, then slowly insert along the shape of the card slot 7, so that the limiting block 9 slides in the card slot 7 until the limiting block 9 is completely embedded in the card slot 7, achieving the installation of the transparent cover plate 8 and the cover plate frame 4. This can facilitate the quick installation of the transparent cover plate 8 and the transparent polyimide display screen body 1, and facilitate the quick replacement in the later stage.

[0035] Embodiment Two: As shown in the following table, which is an improvement on the previous embodiment. Figures 2-7

[0036] Specifically, the positioning seat 5 is externally threaded with a positioning bolt 6, and the positioning bolt 6 is provided with two groups of the same two, each group of the positioning bolt 6 is provided with two of the same, and the two groups of the positioning bolt 6 are symmetrically distributed about the center line of the cover plate frame 4. When the overall device needs to be fixed to the mounting rack, the positioning bolt 6 can be inserted through the positioning seat 5 and then installed on the outer surface of the positioning rack, achieving the fixation of the overall device. When the positioning bolt 6 is not needed, it can be not installed, which can improve the versatility of the overall display screen cover plate.

[0037] Specifically, the sealing gasket 10 is a rubber sealing gasket, and the sealing gasket 10 is located between the cover plate frame 4 and the transparent cover plate 8. The rubber sealing gasket 10 plays an effective sealing role between the cover plate frame 4 and the transparent cover plate 8, which can prevent dust, water vapor, oil stains and other external impurities from entering the display screen, protecting the optical and electrical properties of the display screen from being affected. In a humid environment, the sealing gasket 10 can prevent water vapor from entering, avoiding problems such as water mist and short circuit of the display screen.

[0038] Specifically, the cover plate frame 4 is externally inserted with a limiting strip 11, and the limiting strip 11 is in contact with the transparent polyimide display screen body 1 and located at one end of the limiting groove 12 close to the transparent cover plate 8. After the transparent polyimide display screen body 1 and the transparent cover plate 8 are both installed on the cover plate frame 4, the limiting strip 11 is inserted along the reserved slot on the outer surface of the cover plate frame 4, so that it is in close contact with the transparent polyimide display screen body 1 and located at one end of the limiting groove 12 close to the transparent cover plate 8, which can further strengthen the fixation of the transparent polyimide display screen body 1, prevent it from shifting in the direction perpendicular to the plane of the display screen, and also play a certain buffering role, improving the practicality of the overall cover plate structure.

[0039] ​Working principle: in use, the transparent polyimide display screen body 1 is installed through the cooperation of the limiting frame 2 on its outer surface and the limiting groove 12 on the inner surface of the cover frame 4, the rubber protective sleeve 13 in the limiting groove 12 plays a buffering and positioning auxiliary role, so that the transparent polyimide display screen body 1 can be accurately and stably embedded into the cover frame 4. At the same time, the outer surface of the cover frame 4 is connected with the positioning bolt 6 through the positioning seat 5 and the threaded connection, so as to firmly fix the whole cover structure on the corresponding position of the equipment, so as to ensure that it will not be displaced or loosened during the operation of the equipment, and the multiple groups of symmetrically distributed positioning bolts 6 can realize accurate positioning adjustment, ensure the cooperation precision with other parts of the equipment, and the transparent cover plate 8 is inserted and installed with the clamping groove 7 in the inverted "Z" shape structure on the inner surface of the cover frame 4 through the limiting block 9 at one end. The special structure of the clamping groove 7 makes the limiting block 9 be effectively limited in multiple directions after being inserted, so as to realize the firm fixation of the transparent cover plate 8 on the cover frame 4, and the installation process is relatively simple and efficient. Between the transparent cover plate 8 and the cover frame 4, the rubber sealing gasket 10 is also arranged, after the transparent cover plate 8 is installed in place, it is tightly pressed on the sealing gasket 10, forming a sealing structure, preventing foreign matters from invading from outside. In addition, the limiting strip 11 inserted and installed on the outer surface of the cover frame 4 is in contact with the transparent polyimide display screen body 1 and located at a specific position, further assisting in fixing and protecting the transparent polyimide display screen body 1, and enhancing the stability of the whole structure.

[0040] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, the scope of the present application is defined by the appended claims and their equivalents.
