[0030] Reference Figure 1 and Figure 2 As shown, the utility model provides a technical solution: a high temperature resistant LED display module, comprising a module body 1, a back cover 2 is installed on one side of the module body 1, a heat dissipation hole is opened on the surface of the back cover 2, and a dustproof device 3 is provided on the surface of the back cover 2. By setting the dustproof device 3, the effect of preventing dust from entering the module body 1 through the heat dissipation holes of the back cover 2 is achieved, and a large amount of dust is prevented from entering the module body 1 through the heat dissipation holes of the back cover 2, resulting in a large amount of dust covering the internal circuit of the module body 1, thereby affecting the heat dissipation of the module body 1, thereby improving the practicality of the device, and disassembly devices 4 are provided on both sides of the module body 1. By setting the disassembly device 4, the effect of quickly disassembling and separating the module body 1 and the back cover 2 is achieved, and when the staff needs to inspect the inside of the module body 1, the connection between the module body 1 and the back cover 2 is too tight, resulting in the staff having to use tools or violent disassembly, thereby causing damage to the module body 1, thereby improving the practicality of the device.

[0031] The specific arrangement and function of the dustproof device 3 and the disassembly device 4 will be described in detail below.

[0032] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in this embodiment: the dustproof device 3 includes a dustproof frame 301, the dustproof frame 301 is fixedly connected to the surface of the back cover 2, the upper surface of the dustproof frame 301 is fixedly connected with two L-shaped plates 302, the two L-shaped plates 302 are fixedly connected with a rotating rod 303 on the side close to each other, the arc surface of the rotating rod 303 is rotatably connected with a connecting plate 304, one side of the connecting plate 304 is fixedly connected with a dustproof net 305, the side of the dustproof net 305 away from the connecting plate 304 is slidably connected to the dustproof frame 301, the surface of the dustproof net 305 is fixedly connected with a special-shaped block 306, the side of the back cover 2 close to the dustproof frame 301 is fixedly connected with a fixing plate 307, one side of the fixing plate 307 is fixedly connected with a fixing rod 308, and the arc surface of the fixing rod 308 is slidably connected with an operating The operating plate 309 is fixedly connected with a plug rod 310 on one side of the operating plate 309 close to the fixed plate 307, and a slot is provided on the surface of the special-shaped block 306. When the staff has placed the dust screen 305, they push the operating plate 309 to slide on the arc surface of the fixed rod 308. At the same time, the operating plate 309 drives the plug rod 310 to move until the plug rod 310 is inserted into the slot of the special-shaped block 306. At this time, the effect of limiting the movement of the dust screen 305 is achieved, and the module body 1 is prevented from rotating on the arc surface of the rotating rod 303 after being hit by an external force, thereby causing the dust screen 305 to be forced to open. The end of the fixed rod 308 away from the fixed plate 307 is fixedly connected to the limiting plate 311, and the size of the plug rod 310 is similar to that of the fixed rod 308. The size of the slot of the special-shaped block 306 is adapted. When the staff pulls the operating plate 309, the operating plate 309 slides on the arc surface of the fixed rod 308. At this time, the limit plate 311 achieves the effect of limiting the maximum sliding distance of the operating plate 309 on the fixed rod 308, thereby avoiding the situation that the operating plate 309 is separated from the arc surface of the fixed rod 308 due to the difficulty in fully controlling the pulling force when the staff pulls the operating plate 309. The arc surface of the fixed rod 308 is sleeved with a first spring 312, and the two ends of the first spring 312 are fixedly connected to the operating plate 309 and the fixed plate 307 respectively. When the staff releases the operating plate 309, the resilience of the first spring 312 drives the operating plate 309 to slide on the arc surface of the fixed rod 308, and at the same time When the staff releases the restriction of the special-shaped block 306 by the plug rod 310, the torsion force of the torsion spring 313 drives the connecting plate 304 to rotate on the arc surface of the rotating rod 303. At the same time, the connecting plate 304 drives the dustproof net 305 to rotate until the dustproof net 305 is opened. At this time, the torsion spring 313 achieves the effect of automatically opening the dustproof net 305.In order to reduce the operating steps of the staff on the device, the work efficiency of the staff is improved.

[0033] Reference Figure 2 and Figure 6 As shown, specifically, the disassembly device 4 includes two plug plates 41, and the two plug plates 41 are fixedly connected to the two sides of the module body 1 respectively. Both sides of the back cover 2 are fixedly connected with a U-shaped frame 42, and the surface of the plug plate 41 is slidably connected to the U-shaped frame 42. The side of the plug plate 41 away from the module body 1 is fixedly connected with an L-shaped frame 43, and the L-shaped frame 43 is internally threaded with a driving rod 44. One end of the driving rod 44 is rotatably connected with a connecting block 45, and a connecting hole is opened on the surface of the plug plate 41. The side of the connecting block 45 close to the driving rod 44 is fixedly connected A positioning rod 46 is connected, and the arc surface of the positioning rod 46 is slidably connected to the L-shaped frame 43. When the staff rotates the driving rod 44, the driving rod 44 moves in the internal thread of the L-shaped frame 43. At the same time, the driving rod 44 drives the connecting block 45 to move, and the connecting block 45 drives the positioning rod 46 to slide in the L-shaped frame 43. At this time, the positioning rod 46 has the effect of limiting the connection block 45 from rotating with the driving rod 44, so that the staff can quickly insert the connection block 45 into the connection hole of the plug plate 41, thereby improving the work efficiency of the staff.

[0034] Working principle: when the staff needs to prevent dust from entering the module body 1 through the heat dissipation holes of the back cover 2, the operating plate 309 is pulled to make the operating plate 309 slide on the arc surface of the fixed rod 308, and the first spring 312 is stretched. At the same time, the operating plate 309 drives the insertion rod 310 to move until the insertion rod 310 no longer blocks the movement of the special-shaped block 306. At this time, the dustproof net 305 is pressed, and the dustproof net 305 drives the connecting plate 304 to rotate on the arc surface of the rotating rod 303. At the same time, the dustproof net 305 drives the special-shaped block 306 to move until the dustproof net 305 and the surface of the dustproof frame 301 are aligned. The surfaces fit together, and the operating plate 309 is released at this time. The resilience of the first spring 312 drives the operating plate 309 to slide on the arc surface of the fixing rod 308, and at the same time, the operating plate 309 drives the insertion rod 310 to move until the insertion rod 310 is inserted into the slot of the special-shaped block 306. At this time, the effect of preventing dust from entering the module body 1 through the heat dissipation holes of the back cover 2 is achieved, and a large amount of dust is prevented from entering the module body 1 through the heat dissipation holes of the back cover 2, resulting in the internal circuits of the module body 1 being covered with a large amount of dust, thereby affecting the heat dissipation of the module body 1, thereby improving the practicability of the device.

[0035] When the staff needs to quickly disassemble and repair the module body 1 and the back cover 2, the driving rod 44 is rotated, and the driving rod 44 moves in the internal thread of the L-shaped frame 43. At the same time, the driving rod 44 drives the connecting block 45 to move, and the connecting block 45 drives the positioning rod 46 to slide in the L-shaped frame 43 until the connecting block 45 is disengaged from the connecting hole of the plug plate 41. At this time, the module body 1 is pulled, and the module body 1 drives the plug plate 41 to slide in the U-shaped frame 42 until the plug plate 41 is completely disengaged from the U-shaped frame 42. At this time, the module body 1 and the back cover 2 are quickly disassembled and separated, which avoids the situation that the connection between the module body 1 and the back cover 2 is too tight when the staff needs to repair the inside of the module body 1, resulting in the staff having to use tools or violent disassembly, thereby causing damage to the module body 1, thereby improving the practicability of the device.
