[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 5 , an indoor waterproof and moisture-proof LED display screen module, comprising a shell 1, an inner cavity is provided in the shell 1, the LED display screen module can be placed in the inner cavity, a glass screen 2 is provided on the front inner wall of the inner cavity, a first rectangular inner groove 3 is vertically opened at the upper end of the shell 1, a desiccant can be placed in the first rectangular inner groove 3, a plurality of first circular through grooves 4 are vertically opened at the inner bottom of the first rectangular inner groove 3, second rectangular inner grooves 5 are horizontally opened on the left and right inner walls of the first rectangular inner groove 3, the inner walls of the two second rectangular inner grooves 5 are slidably connected with L-shaped connecting plates 6, the two L-shaped connecting plates 6 are composed of a horizontal part and a vertical part, the horizontal parts of the two L-shaped connecting plates 6 are provided with dust-proof nets 7, the two dust-proof nets 7 can effectively prevent dust from entering the shell 1 during ventilation and heat dissipation, and the two L-shaped connecting plates 6 are slidably connected to the inner wall of the first rectangular inner groove 3;

[0023] Among them, it also includes a limiting mechanism, which is used to limit the two L-shaped connecting plates 6. The limiting mechanism includes a first connecting block 8 fixed to the upper end of the shell 1, and a C-shaped limiting block 9 that can move forward and backward is arranged on the upper end of the shell 1. The front end of the C-shaped limiting block 9 passes through the first connecting block 8 and is slidably connected to the first connecting block 8. The C-shaped limiting block 9 cooperates with the vertical parts of the two L-shaped connecting plates 6. When the two L-shaped connecting plates 6 move toward each other to the middle position of the first rectangular inner groove 3, the front end of the C-shaped limiting block 9 can limit the two L-shaped connecting plates 6. The rear inner wall of the C-shaped limiting block 9 is elastically connected to the first connecting block 8 by two springs 10. The two springs 10 can control the limiting of the two L-shaped connecting plates 6 by the C-shaped limiting block 9. The upper end of the C-shaped limiting block 9 is fixedly connected to the first connecting strip 11;

[0024] It also includes a back cover mechanism, which is used to facilitate the installation of the display screen module and provide heat dissipation for it. The back cover mechanism includes a back cover body 12 arranged on the back side of the shell 1. The back cover body 12 is fixedly connected to the shell 1 by four limit bolts 13. Two third rectangular inner grooves 14 are horizontally opened on the front side of the back cover body 12. The rear inner walls of the two third rectangular inner grooves 14 are horizontally opened with multiple second circular through grooves 15. Cooling fans 16 are installed in the two third rectangular inner grooves 14. A replaceable battery (not shown) that can provide kinetic energy for the two cooling fans 16 is arranged in the back cover body 12.

[0025] In the present invention, before use, first remove the rear cover body 12 by removing the four limit bolts 13, then place the LED display module into the inner cavity, and finally fix the rear cover body 12 to the rear side of the housing 1 by the four limit bolts 13;

[0026] After installing the LED display module, control the two L-shaped connecting plates 6 to move in opposite directions, place the desiccant in the first rectangular inner groove 3, and then control the two L-shaped connecting plates 6 to move toward each other. When the vertical parts of the two L-shaped connecting plates 6 are respectively in contact with the left and right sides of the C-shaped limit block 9, push the first connecting strip 11 backward to drive the C-shaped limit block 9 to move backward until the C-shaped limit block 9 is no longer in contact with the two L-shaped connecting plates 6. At this time, the two springs 10 will be stretched by force, and then continue to control the two L-shaped connecting plates 6 to move toward each other. , until the facing sides of the two L-shaped connecting plates 6 are moved to the middle line position of the first rectangular inner groove 3, the first connecting strip 11 is loosened, and the C-shaped limit block 9 will be moved forward by the force of the two springs 10, so that the front part of the C-shaped limit block 9 will clamp the vertical parts of the two L-shaped connecting plates 6 in the middle, thereby completing the limit. When the desiccant needs to be replaced later, the limit of the two L-shaped connecting plates 6 by the C-shaped limit block 9 is first released, and then the two L-shaped connecting plates 6 are controlled to move back to each other to replace the desiccant;

[0027] When using the LED display module, two cooling fans 16 can be started. The two cooling fans 16 can transport external air along the path of two dust-proof nets 7 → multiple first circular grooves 4 → inner cavity → two third rectangular inner grooves 14, and finally discharge it from the inner cavity through multiple second circular grooves 15. In this way, heat dissipation of the LED display module can be achieved through cyclic ventilation, and in the process of ventilation and heat dissipation, the two dust-proof nets 7 can effectively prevent dust from entering the inner cavity.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
