[0041] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.

[0042] A LED display screen, referring to Figure 1 and Figure 2 , including a display screen body 1, a plurality of heat dissipation openings 11 are arranged on the back of the display screen body 1, a heat dissipation grid 2 is detachably connected in each heat dissipation opening 11, and the display screen body 1 dissipates heat and prevents dust through the heat dissipation grid 2 of the heat dissipation opening 11. Specifically, a groove is arranged on the bottom wall of the heat dissipation grid 2, a protrusion is fixedly connected to the bottom wall of the heat dissipation opening 11, and the protrusion is inserted into the groove to realize the sliding connection of the heat dissipation grid 2 in the heat dissipation opening 11, and a fixing component is arranged on the top wall of the heat dissipation opening 11, and the heat dissipation grid 2 is fixed by the fixing component to limit the movement of the heat dissipation grid 2, so that the heat dissipation grid 2 is fixed in the heat dissipation opening 11, and the heat dissipation grid 2 is removed by releasing the fixing component, and the heat dissipation grid 2 is dusted.

[0043] Reference Figure 2 and Figure 3The heat dissipation grid 2 includes an outer frame 21, a brush 22 and a plurality of baffles 23. The outer frame 21 is annular. In the present embodiment, the outer frame 21 is square. An installation space 211 is provided in the middle of the outer frame 21. The plurality of baffles 23 are evenly spaced in the installation space 211 and are fixedly connected to the outer frame 21. The plurality of baffles 23 are tilted from top to bottom and are parallel to each other. The brush 22 is provided between the baffle 23 at the top and the inner wall of the outer frame 21 and is detachably connected to the outer frame 21. When the heat dissipation grid 2 is disassembled, the brush 22 on the outer frame 21 can be disassembled, and the brush 22 is used to clean the baffles 23 and the outer frame 21 without the user having to bring the brush 22, which is convenient for the user to use.

[0044] The brush 22 includes a sheet 221 and bristles 222. The sheet 221 is detachably connected to the outer frame 21. There are several bristles 222, which are fixedly connected to the sheet 221. The sheet 221 is tilted from top to bottom and is parallel to the baffles 23. During normal use of the heat dissipation grid 2, the sheet 221 and the baffles 23 both play a dust-proof role. When the baffles 23 need to be cleaned, the sheet 221 is disassembled and the baffles 23 are cleaned using the bristles 222.

[0045] Specifically, connecting blocks 223 are fixedly connected on both sides of the sheet body 221, and slots 212 are opened on the two symmetrical inner walls of the outer frame 21. The two slots 212 and the positions of the two connecting blocks 223 are arranged in a one-to-one correspondence. A second magnet 25 is fixedly connected in each slot 212, and a first magnet 24 is fixedly connected to each connecting block 223. When the connecting block 223 is completely inserted into the slot 212, the first magnet 24 and the second magnet 25 are attracted to each other.

[0046] Furthermore, the slot 212 is fan-shaped, the second magnet 25 is fixedly connected to the inner bottom wall of the slot 212, the inner top wall of the slot 212 is fixedly connected to the third magnet 26, the top wall of the connecting block 223 is also fixedly connected to the third magnet 26, and the connecting block 223 is inserted into the slot 212 and can rotate in the slot 212. When the connecting block 223 rotates to the point where the first magnet 24 and the second magnet 25 are attracted to each other, the sheet 221 is parallel to the blocking sheet 23, and when the connecting block 223 rotates to the point where the inner top wall of the slot 212 abuts, the two third magnets 26 are attracted to each other, and at this time the sheet 221 is arranged horizontally.

[0047] Specifically, an arc-shaped notch 213 is provided in the slot 212, and an arc-shaped protrusion 224 is provided at one end of the connecting block 223 inserted into the slot 212. When the connecting block 223 is fully inserted into the slot 212, the arc-shaped protrusion 224 is inserted into the arc-shaped notch 213 and can rotate in the arc-shaped notch 213, and the connecting block 223 rotates around the center of the arc-shaped notch 213.

[0048] Furthermore, an arc column 3 is fixedly connected in the slot 212, and the center of the arc column 3 coincides with the center of the arc notch 213. A limiting hole 225 is provided on the connecting block 223, and the arc column 3 can be inserted into the limiting hole 225. When the connecting block 223 rotates, the arc column 3 slides in the limiting hole 225. By setting the arc column 3, the position of the connecting block 223 is limited, thereby reducing the occurrence of positional displacement of the connecting block 223 during rotation.

[0049] A gap 4 is provided between the top surface of the arc column 3 and the inner top wall of the slot 212, and the gap 4 is adapted to the thickness of the connecting block 223. When the connecting block 223 is rotated to fit the top wall of the slot 212, the arc column 3 is disengaged from the limiting hole 225. The connecting block 223 can be pulled out of the gap 4 by pulling the connecting block 223, thereby completing the disassembly of the brush 22.

[0050] Specifically, when the connecting block 223 rotates to fit the top wall of the slot 212, the two third magnets 26 are attracted to each other. At this time, the fixing component releases the limit on the outer frame 21, pulls the brush 22, and drives the outer frame 21 to slide, thereby realizing the disassembly of the outer frame 21. After the disassembly of the outer frame 21 is completed, press the outer frame 21 and pull out the brush 22 to clean the dust.

[0051] Furthermore, in order to facilitate the pulling out of the outer frame 21 , a ridge 7 is fixedly connected to the sheet body 221 . When pulling the brush 22 , the ridge 7 can be buckled, which is convenient for the user to exert force.

[0052] The fixing assembly includes a spring 5 and a latch 6. A telescopic slot is provided on the top wall of each heat dissipation port 11. The latch 6 is slidably connected in the telescopic slot. The spring 5 is arranged between the latch 6 and the inner wall of the telescopic slot. One end of the spring 5 is fixedly connected to the inner wall of the telescopic slot, and the other end of the spring 5 is fixedly connected to the latch 6. A plug hole 214 is provided on the top wall of the outer frame 21. The plug hole 214 is connected to the installation space 211. A second inclined surface 61 is provided on the latch 6. When the outer frame 21 is pushed into the heat dissipation port 11, the latch 6 slides into the telescopic hole under the guidance of the second inclined surface 61. When the telescopic hole corresponds to the position of the plug hole 214, the spring 5 drives the latch 6 to be inserted into the plug hole 214 and then inserted into the installation space 211.

[0053] A first inclined surface 215 is provided on the inner wall of the insertion hole 214. When the outer frame 21 needs to be disassembled, the sheet 221 is rotated to make the connecting block 223 abut against the top wall of the slot 212. At this time, the connecting block 223 pushes the latch 6 out of the installation space 211, and then the outer frame 21 is pulled so that the latch 6 slides into the telescopic groove under the guidance of the first inclined surface 215, thereby releasing the limit on the outer frame 21 and realizing the disassembly of the outer frame 21.

[0054] The implementation principle of the embodiment of the present application is: when the heat dissipation grille 2 needs to be disassembled, the sheet 221 is rotated to make the connecting block 223 abut against the top wall of the slot 212, thereby pushing the pin 6 out of the socket 214, and then pulling the sheet 221 to drive the outer frame 21 to slide out of the heat dissipation port 11. At this time, the brush 22 is pulled out to clean the heat dissipation grille 2.

[0055] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
