[0024] Example 1

[0025] In this embodiment, if Figure 1-Figure 4 As shown, the front-and-back maintainable LED display screen includes a display screen body 101, a mounting frame 102 is fixedly connected to the outer side of the display screen body 101, the mounting frame 102 realizes protection of the display screen body 101, and also includes a mounting mechanism 200, a dust removal mechanism 300 and a heat dissipation mechanism 400 fixedly connected to the display screen body 101, for realizing installation of the display screen body 101, the dust removal mechanism 300 is arranged on one side of the display screen body 101, for realizing dust removal operation on the surface of the display screen body 101, the heat dissipation mechanism 400 is arranged on one side of the mounting mechanism 200, for improving the heat dissipation effect of the display screen body 101, before the front-and-back maintainable LED display screen starts to be used, first check whether the display screen can be used normally, and then adjust the dust removal mechanism 300 and the heat dissipation mechanism 400 so that the display screen enters a standby state.

[0026] Among them Figure 2 As shown, the mounting mechanism 200 includes a mounting bar 201 symmetrically arranged on one side of the display screen body 101, a groove is provided on the surface of the mounting bar 201, a rotating shaft is fixedly connected inside the groove, a mounting plate 202 is rotatably connected to the outer side of the rotating shaft, and a plurality of mounting holes 203 are provided on the side of the mounting plate 202 away from the rotating shaft, and the display screen body 101 is installed through the mounting holes 203.

[0027] Among them Figure 1-Figure 4 As shown, the dust removal mechanism 300 includes slide grooves 301 symmetrically arranged on the left and right sides of the installation frame 102, and screw rods 302 and guide rods 303 are respectively installed in the two slide grooves 301. One end of the screw 302 extends to the outside of the slide groove 301 and is fixedly connected to the output end of the driving motor. The driving motor is started to drive the screw 302 to rotate, thereby driving the corresponding movable sleeve 304 to move. The inside of the slide groove 301 is slidably connected with the movable sleeve 304, and the outer side of the screw 302 is threadedly connected to one of the movable sleeves 304. The two movable sleeves 304 drive the detachable components to move up and down on the slide groove 301 to increase the structural stability. The guide rod 303 is slidably connected to the other movable sleeve 304, and a detachable component is installed on one side of the movable sleeve 304 to facilitate the replacement and installation of the cleaning cloth 314.

[0028] Among them Figure 2 As shown, the heat dissipation mechanism 400 includes a heat conducting plate 401 fixedly connected to the back of the display screen body 101, four heat conducting plates 401 are symmetrically provided, and the heat conducting plates 401 are fixedly connected to the heat dissipation fins 402. The heat conducting plates 401 and the heat dissipation fins 402 are used together to guide the heat generated during the use of the display screen body 101 into the air, so as to assist the display screen body 101 to dissipate heat better;

[0029] Among them Figure 3-Figure 4 As shown, the detachable component includes a connecting block 305 fixedly connected to the movable sleeve 304. The movable sleeve 304 moves, thereby driving the connecting block 305 to move. The two connecting blocks 305 are fixedly connected to the limiting block 308 on the opposite side. The limiting block 308 is used to place the stop bar 310. A plug-in block 307 slidably connected to the connecting block 305 is provided above the limiting block 308. The plug-in block 307 is threadedly connected to the screw rod 306. The upper end of the screw rod 306 penetrates and extends out of the connecting block 305 and is fixedly connected to the knob. When the knob is rotated, the screw rod 306 rotates to drive the plug-in block 307 to move. The plug-in block 307 is plugged into the plug-in slot 309. The plug-in slots 309 are symmetrically arranged on both sides of the upper surface of the stop bar 310. The plug-in block 307 moves to connect or disengage with the plug-in slot 309, thereby realizing the fixing and removal of the stop bar 310. A cleaning component is provided on the side of the stop bar 310 close to the display screen body 101, thereby realizing the cleaning operation of the display screen body 101.

[0030] Among them Figure 3-Figure 4As shown, the cleaning assembly includes a pressure strip 313, which is arranged on the side of the stop bar 310 close to the display screen body 101. The stop bar 310 and the pressure strip 313 are connected by a plurality of evenly distributed elastic columns 311. The outer side of the elastic column 311 is sleeved with a spring 312, and the spring 312 enables the elastic column 311 to have the ability to automatically return to its original position. Through the coordinated use of the elastic column 311 and the spring 312, interference or damage to the display screen body 101 can be avoided during the cleaning process. A cleaning cloth 314 is installed on the side of the pressure strip 313 close to the display screen body 101 to achieve the cleaning operation of the screen;

[0031] Example 2

[0032] The difference from Example 1 is that Figure 2 As shown, the installation bars 201 are fixedly connected with reinforcing ribs 204, and the reinforcing ribs 204 make the installation and fixation of the display screen body 101 more firmly, thereby increasing the overall stability effect;

[0033] Among them Figure 4 As shown, the dimensions of the plug-in block 307 and the plug-in slot 309 are matched, and the connection and disassembly between the blocking bar 310 and the connecting block 305 are achieved through the mutual cooperation between the plug-in block 307 and the plug-in slot 309 .

[0034] When in use, the display screen body 101 is installed and fixed through the mounting plate 202 and the mounting hole 203, the driving motor is started, the screw rod 302 rotates, and the stop bar 310 is driven to move up and down with the cooperation of the screw rod 302, the guide rod 303, and the movable sleeve 304, thereby driving the pressure bar 313 and the cleaning cloth 314 to move up and down, so as to achieve rapid cleaning of the surface of the display screen body 101. After long-term use, the cleaning effect of the cleaning cloth 314 deteriorates. The screw rod 306 can be rotated by rotating the knob, and then the plug-in block 307 moves, so that the plug-in block 307 is disengaged from the plug-in slot 309, so that the stop bar 310 can be removed, and then the entire cleaning assembly can be replaced to ensure the cleaning effect. At the same time, the heat conduction plate 401 and the heat dissipation fins 402 on the back of the display screen body 101 introduce heat into the air, which assists the display screen body 101 in dissipating heat and increases its service life.

[0035] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
