[0002] An LED display screen is a display panel composed of light-emitting diodes, which is used to display various information such as text, images or videos. Due to its high brightness, vivid colors, wide viewing angle and other characteristics, the LED display screen has been widely used in many fields such as advertising, information display, stage performances, sports events, traffic indications, etc. By selecting different technical parameters and types, the requirements of different occasions can be met.

[0003] The patent with the patent authorization announcement number CN217588350U discloses an LED display screen. The LED display screen includes: a box body; an LED module arranged on the box body. The box body includes a box body main body and a support rib arranged on one side of the box body main body facing the LED module. The LED module includes an LED lamp board and a heating unit. The outer edge of the LED lamp board is attached to the support rib. Although the above patent can solve the problem that the heat dissipation of the LED display screen in the related technology is uneven, resulting in poor overall display effect of the LED display screen, in actual application, when the LED display screen is not in use, it is easy to accumulate dust. The dust may cover the surface of the LED lamp board, blocking the normal emission of light, resulting in a decrease in display brightness. In addition, the dust covering will cause uneven color display, affecting the overall visual effect.

[0004] Therefore, there is a particular need for an LED display screen with a dust-proof function to solve the above problems. Content of the Utility Model

[0025] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0026] Embodiment: An LED display screen with a dust-proof function, refer to Figures 1 - 8As shown in the figure, it includes an LED display body 1, an installation housing 2, a covering roller blind 3, a hook-shaped buckle 4, a rotating shaft 5, a torsion spring 6, a protective sleeve 12 and an anti-blue light film 13. At the outer bottom of the LED display body 1, card holes 102 are provided in a left-right distribution. The upper outer part of the LED display body 1 is connected to the installation housing 2 by bolts. Inside the installation housing 2, a rotating shaft 5 is rotatably connected. A covering roller blind 3 is wound around the outside of the rotating shaft 5. One end of the covering roller blind 3 is fixedly connected to the outside of the rotating shaft 5. And the covering roller blind 3 is made of acrylic, having good weather resistance and not easily aging. The other end of the covering roller blind 3 not connected to the rotating shaft 5 is connected to two hook-shaped buckles 4 by welding. And the two hook-shaped buckles 4 are distributed on the left and right sides of the other end of the covering roller blind 3 and can be respectively clamped with the two card holes 102. Torsion springs 6 are sleeved on the left and right ends of the rotating shaft 5. The two ends of the torsion spring 6 are respectively connected to the installation housing 2 and the rotating shaft 5. Inside the card hole 102, a protective sleeve 12 is connected by welding. And the protective sleeve 12 is made of rubber, which can achieve a good anti-wear effect. An anti-blue light film 13 is pasted on the front side of the outside of the LED display body 1. Two grooves 14 are provided on the rear side of the outside of the LED display body 1. One of the grooves 14 is located on the left rear side of the outside of the LED display body 1, and the other groove 14 is located on the lower rear side of the outside of the LED display body 1, which is convenient for holding the LED display body 1 horizontally or vertically.

[0027] Refer to Figure 1 , Figure 3 , Figure 6 and Figure 8 As shown in the figure, it also includes a bearing wall 101, a covering keel 7 and a cassette bearing keel 8. On the front side of the outside of the bearing wall 101, covering keels 7 are connected in a left-right distribution by bolts. On the rear side of the outside of the LED display body 1, cassette bearing keels 8 are connected in an up-down distribution by bolts. And the cassette bearing keels 8 are clamped with the covering keels 7, so that the LED display body 1 is fixed on the bearing wall 101.

[0028] Refer to Figures 6 - 7 As shown in the figure, it also includes an installation frame 9, a heat dissipation fan 10 and a heat conduction plate 11. On the rear side of the outside of the LED display body 1, an installation frame 9 is connected by bolts. On the rear side inside the installation frame 9, heat dissipation fans 10 are connected in a left-right distribution by bolts. On the front side inside the installation frame 9, a heat conduction plate 11 is connected by bolts. The heat conduction plate 11 is facing the front of the heat dissipation fan 10. And the front side of the heat conduction plate 11 is attached to the rear side of the LED display body 1, which can ensure that the heat generated by the LED display body 1 is quickly conducted to the heat conduction plate 11.

[0029] When the LED display screen needs to be used, first, the user installs the bearing wall 101 on the wall surface. Subsequently, the cassette bearing keel 8 is snapped into the appropriate position of the covering keel 7 to ensure that the cassette bearing keel 8 is closely attached to and clamped with the covering keel 7, fixing the LED display screen body 1. Then, the LED display screen body 1 is turned on to display an image. The anti-blue light film 13 can reduce the harm of blue light to the eyes, improving the protection performance and viewing comfort of the LED display screen body 1. When the LED display screen body 1 operates, it generates heat, which is absorbed by the heat conduction plate 11. At this time, the cooling fan 10 is turned on, and the cooling fan 10 operates to blow the heat on the heat conduction plate 11 to the outside, enabling the heat conduction plate 11 to continuously absorb heat and preventing the temperature of the LED display screen body 1 from being too high. When the LED display screen is not needed, the LED display screen body 1 and the cooling fan 10 are turned off. Hold the other end of the covering roller blind 3 and pull it out from the rotating shaft 5 until the covering roller blind 3 completely covers the surface of the LED display screen body 1. During the process of pulling out the covering roller blind 3, the covering roller blind 3 drives the rotating shaft 5 to rotate clockwise, and the torsion spring 6 deforms accordingly. Then, the hook-shaped buckle 4 is snapped into the corresponding card hole 102 to fix the covering roller blind 3. When snapping, the protective sleeve 12 can prevent the card hole 102 from being worn. When the LED display screen is used next time, the hook-shaped buckle 4 is disengaged from the corresponding card hole 102 to release the covering roller blind 3, and the torsion spring 6 returns to its original shape, prompting the rotating shaft 5 to rotate counterclockwise to retract the covering roller blind 3. Finally, repeat the above steps to use the LED display screen.

[0030] It should be noted that when it is necessary to disassemble the LED display screen body 1, the cassette bearing keel 8 is separated from the covering keel 7, and then it can be easily disassembled.

[0031] Although the present invention has been described with reference to the exemplary embodiments, it should be understood that the present invention is not limited to the disclosed exemplary embodiments. The scope of the following claims should be given the broadest interpretation so as to cover all modifications and equivalent structures and functions.
