[0023] Embodiment 1

[0024] Referring to Figures 1-6 , an LED display screen convenient for heat dissipation, including a screen body 1, one side of the screen body 1 is fixedly connected with a rear cover 2, the side of the rear cover 2 away from the screen body 1 is fixedly connected with a vertical rod 3, the bottom of the vertical rod 3 is fixedly connected with a bottom plate 4, a mounting groove is opened at the top of the rear cover 2, a mounting plate 5 is arranged at the top of the mounting groove, the bottom of the mounting plate 5 is fixedly connected with a copper sheet 6, multiple groups of the copper sheets 6 are provided and are parallelly distributed at the bottom of the mounting plate 5, a ventilation hole 7 is opened on one side of the copper sheet 6, multiple groups of the ventilation holes 7 are provided and are parallelly distributed on one side of the copper sheet 6, and multiple groups of the copper sheets 6 are inserted into the inner wall of the mounting groove. One side of the vertical rod 3 away from the rear cover 2 is fixedly connected with a connecting plate 8, the top of the connecting plate 8 is fixedly connected with a horizontal plate 9, both sides of the horizontal plate 9 are fixedly connected with a fan 10, one side of the fan 10 is fixedly connected with a housing 11, the fan 10 faces the rear cover 2, and two groups of the horizontal plates 9 are provided and are symmetrically distributed at the top and bottom of the connecting plate 8.

[0025] To solve the problem that heat is difficult to dissipate after the LED display screen is used for a long time, when heat dissipation treatment is required for the LED display screen, multiple groups of copper sheets 6 can be inserted into the installation grooves provided at the top of the rear cover 2. When the copper sheets 6 are inserted to the bottom of the installation grooves, the position of the copper sheets 6 can be fixed by the mounting plate 5. Subsequently, the fan 10 can be turned on. The cover plate provided outside the fan 10 can protect the fan blades inside the fan 10. When the fan 10 rotates, it will generate suction, and the hot air inside the rear cover 2 will be sucked out through the suction generated by the fan 10. When the hot air passes through the copper sheets 6, the heat in the hot air can be taken away by the copper sheets 6. By providing air holes on one side of the copper sheets 6, the hot air can pass through the air holes. Since there are multiple groups of copper sheets 6, when the hot air passes through the air holes and through multiple groups of copper sheets 6, the cooling efficiency of the hot air will be improved, so that the heat in the rear cover 2 is transferred to the copper sheets 6. After the rear cover 2 is cooled, the mounting plate 5 and the copper sheets 6 can be taken out for separate heat dissipation. By providing two sets of cross plates 9, four groups of fans 10 can be symmetrically installed on one side of the rear cover 2, and the four symmetrically distributed fans 10 can provide uniform suction for the rear cover 2, which is convenient for providing a uniform heat dissipation effect for the rear cover 2.

[0026] Refer to Figure 4 , one side of the mounting plate 5 is fixedly connected with a magnet 12, the top of the rear cover 2 is fixedly connected with an iron block 13, and the magnet 12 is adsorbed on the top of the iron block 13.

[0027] By providing a magnet 12 on one side of the mounting plate 5, after the copper sheet 6 at the bottom of the mounting plate 5 is inserted into the installation groove, the position of the magnet 12 will fit above the iron sheet, so that the magnet 12 adsorbs the iron block 13. After the magnet 12 is adsorbed on the top of the iron block 13, the positions of the mounting plate 5 and the copper sheet 6 can be fixed to prevent the copper sheet 6 from shaking after installation.

[0028] Refer to Figure 4 , the bottom of the mounting plate 5 is fixedly connected with a sealing gasket 14, the material of the sealing gasket 14 is rubber, and the sealing gasket 14 is arranged at the top of the installation groove.

[0029] By providing a sealing gasket 14 made of rubber at the bottom of the mounting plate 5, after the copper sheet 6 is inserted into the interior of the installation groove, it is convenient to seal the connection between the mounting plate 5 and the installation groove through the sealing gasket 14, preventing dust and impurities from falling into the installation groove through the gap between the mounting plate 5 and the installation groove.

[0030] Refer to Figures 1-3 , one side of the vertical rod 3 is fixedly connected with a fixing plate 17, one side of the fixing plate 17 is inclined, and the fixing plate 17 is fixedly connected to the top of the bottom plate 4.

[0031] By arranging a fixing plate 17 on one side of the vertical rod 3, the stability of the installation between the vertical rod 3 and the fixing plate 17 can be improved through the shape of the fixing plate 17, thereby providing stable support for the bottom of the screen body 1.

[0032] Referring to Figure 1 , a collision prevention block 16 is fixedly connected to the outer wall of the screen body 1. Four groups of the collision prevention blocks 16 are provided and are symmetrically distributed at the corners of the screen body 1.

[0033] By arranging four groups of collision prevention blocks 16 at the corners of the screen body 1, after the screen body 1 is installed, it is convenient to provide protection for the corners of the screen body 1 through the collision prevention blocks 16, preventing the corners of the screen body 1 from being damaged by impact.

[0034] Referring to Figure 5 , a handle 15 is fixedly connected to the top end of the mounting plate 5. The handle 15 is square in shape.

[0035] By arranging a square handle 15 on the mounting plate 5, when it is necessary to take out the mounting plate 5 and the copper sheet 6, it is convenient to pull the mounting plate 5 upward by pulling the handle 15, facilitating the release of the adsorption between the magnet 12 and the iron block 13.

[0036] Working principle: To solve the problem that it is difficult for the heat of the LED display screen to dissipate after long-term use, when heat dissipation treatment is required for the LED display screen, multiple groups of copper sheets 6 can be inserted into the installation grooves provided at the top of the rear cover 2. When the copper sheet 6 is inserted to the bottom of the installation groove, by setting a magnet 12 on one side of the mounting plate 5, after the copper sheet 6 at the bottom of the mounting plate 5 is inserted into the installation groove, the position of the magnet 12 will fit above the iron sheet, so that the magnet 12 adsorbs the iron block 13. After the magnet 12 adsorbs on the top of the iron block 13, the positions of the mounting plate 5 and the copper sheet 6 can be fixed to prevent the copper sheet 6 from shaking after installation. By setting a sealing gasket 14 made of rubber at the bottom of the mounting plate 5, after the copper sheet 6 is inserted into the interior of the installation groove, it is convenient to seal the connection between the mounting plate 5 and the installation groove through the sealing gasket 14 to prevent dust and impurities from falling into the installation groove through the gap between the mounting plate 5 and the installation groove. Subsequently, the fan 10 can be turned on. The cover plate provided outside the fan 10 can protect the fan blades in the fan 10. When the fan 10 rotates, it will generate suction, and the hot air in the rear cover 2 will be sucked out through the suction generated by the fan 10. When the hot air passes through the copper sheet 6, the heat in the hot air can be taken away by the copper sheet 6. By setting air holes on one side of the copper sheet 6, the hot air can pass through the air holes. Since there are multiple groups of copper sheets 6, when the hot air passes through the air holes and through multiple groups of copper sheets 6, the cooling efficiency of the hot air will be improved, so as to transfer the heat in the rear cover 2 to the copper sheet 6. After the rear cover 2 is cooled, the mounting plate 5 and the copper sheet 6 can be taken out for separate heat dissipation. By setting two cross plates 9, four fans 10 can be symmetrically installed on one side of the rear cover 2, and the four symmetrically distributed fans 10 can provide uniform suction for the rear cover 2, which is convenient to provide a uniform heat dissipation effect for the rear cover 2. By setting a fixing plate 17 on one side of the vertical rod 3, the stability of the installation between the vertical rod 3 and the fixing plate 17 can be improved through the shape of the fixing plate 17, so as to provide stable support for the bottom of the screen body 1. By setting four anti-collision blocks 16 at the corners of the screen body 1, after the screen body 1 is installed, it is convenient to protect the corners of the screen body 1 through the anti-collision blocks 16 to prevent the corners of the screen body 1 from being damaged by impact. By setting a square handle 15 on the mounting plate 5, when it is necessary to take out the mounting plate 5 and the copper sheet 6, it is convenient to pull out the mounting plate 5 upward by pulling the handle 15 to release the adsorption between the magnet 12 and the iron block 13.

[0037] Finally: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
