Detailed implementation mode

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation modes:

[0022] As Figure 1 , Figure 2 shown, the present utility model provides an LED display mask structure, including a mounting frame 103. Above the mounting frame 103, there is a mask body 101. On the top of the mask body 101, there are a number of equally spaced lenses 102. On both the left and right sides of the mask body 101, two insertion holes 104 symmetrically arranged front and back are opened. On the inner bottom wall of the mounting frame 103, a circuit board 105 is fixedly connected. On the top of the circuit board 105, a lamp holder 106 adapted to the size, position and number of the lenses 102 on the top of the mask body 101 is fixedly connected. On the top of a number of lamp holders 106, light-emitting chips 107 are fixedly connected. On the right side of the mounting frame 103, a rectangular groove 108 is opened. Inside the mounting frame 103 on the right side, there is a ventilation and heat dissipation assembly 2 adapted to the size and position of the rectangular groove 108. Inside the left and right side walls of the mounting frame 103, two second grooves 109 symmetrically arranged front and back are opened. Inside the four second grooves 109, clamping assemblies 3 are arranged. At the four corners of the inner bottom wall of the mounting frame 103, fastening assemblies 4 are fixedly connected.

[0023] Prepare the mounting frame 103, fixedly connect the circuit board 105 to its inner bottom wall, install the lamp holder 106 on the top of the circuit board 105, ensure that the position of the lamp holder 106 is accurate and adapted to the size, position and number of the lenses 102 on the top of the mask body 101. Then, fixedly connect the light-emitting chip 107 to the top of the lamp holder 106. The set number of lenses 102 can effectively project the light emitted by the light-emitting chip 107.

[0024] As Figure 3 , Figure 4As shown, the ventilation and heat dissipation component 2 includes a fixed block 201. The right side wall of the fixed block 201 is fixedly connected to the inner wall of the right side of the installation frame 103. Above the front side wall of the fixed block 201, a control device 202 is fixedly connected. On the top of the fixed block 201, a temperature sensor 203 is fixedly connected. Below the front side wall of the fixed block 201, an electric telescopic rod 204 is fixedly connected. The control device 202 is electrically connected to the electric telescopic rod 204 and the temperature sensor 203 respectively.

[0025] As Figure 3 , Figure 4 shown, the output end of the electric telescopic rod 204 is fixedly connected to a slide bar 205. The outer wall of the slide bar 205 is slidably connected to a chute 206. The right side of the chute 206 is fixedly connected to a fixed frame 207 fixedly connected to the inner wall of the rectangular groove 108. A plurality of fan blades 208 are rotatably connected to the upper and lower opposite surfaces of the fixed frame 207 at equal distances in the front and back directions. At the bottom of each of the plurality of fan blades 208, an adjustment block 209 is fixedly connected. At the bottom of each of the plurality of adjustment blocks 209, a cylindrical slider 210 is fixedly connected. The outer walls of the plurality of cylindrical sliders 210 are slidably connected to grooves 211 opened on the top of the slide bar 205.

[0026] When the temperature sensor 203 detects that the temperature inside the installation frame 103 rises to a certain level, the temperature sensor 203 transmits a signal to the control device 202. The control device 202 will control the electric telescopic rod 204 to extend, thereby driving the slide bar 205 connected to the output end of the electric telescopic rod 204 to move forward along the inner wall of the chute 206. The movement of the slide bar 205 drives the cylindrical slider 210 to slide in the groove 211, thereby driving the fan blades 208 fixedly connected to the adjustment block 209 to rotate, making the angle of the fan blades 208 larger, accelerating the air circulation speed, and enhancing the heat dissipation effect.

[0027] When the temperature drops to a suitable range, the electric telescopic rod 204 contracts, the slide bar 205 moves backward along the inner wall of the chute 206, and the angle of the fan blades 208 becomes smaller or even closes, thereby weakening the ventilation and heat dissipation intensity, maintaining the temperature inside the installation frame 103, so as to adapt to the cold weather in winter and improve the adaptability of the device.

[0028] As Figure 5As shown, the clamping assembly 3 includes a telescopic rod 302, and the side of the telescopic rod 302 away from the mask body 101 is fixedly connected to the inner wall of the second groove 109, and the side of the telescopic rod 302 close to the mask body 101 is fixedly connected to the limiting block 304, the outer wall of the telescopic rod 302 is provided with a spring 1 303, the left and right ends of the spring 1 303 are respectively fixedly connected to the inner wall of the second groove 109 and the limiting block 304, the top of the mounting frame 103 is provided with a rectangular groove 2 307 running left and right, the top of the outer wall of the limiting block 304 is fixedly connected with a moving rod 306 slidably connected to the inner wall of the second rectangular groove 307, the side of the mounting frame 103 close to the mask body 101 is provided with a circular groove hole 2 308, and the side of the limiting block 304 close to the mask body 101 is fixedly connected with a fixing rod 305 slidably connected to the inner wall of the second circular groove hole 308, the size and position of the fixing rod 305 are adapted to the plug-in hole 104 and can be plugged into the plug-in hole 104.

[0029] When the mask body 101 is installed, the mask body 101 is moved closer to the installation frame 103, and the plug-in holes 104 on the left and right sides of the mask body 101 will contact the fixing rod 305. The fixing rod 305 moves toward the inside of the groove 2 109 driven by the limit block 304, compressing the spring 1 303, and the telescopic rod 302 contracts. When the plug-in hole 104 moves to completely correspond to the position of the fixing rod 305, under the elastic force of the spring 1 303, the fixing rod 305 is inserted into the plug-in hole 104 to realize the clamping fixation of the mask body 101 and the installation frame 103. The moving rod 306 on the top of the outer wall of the limit block 304 slides on the inner wall of the rectangular groove 2 307, which plays a role in guiding and stabilizing the movement of the limit block 304. When disassembling, you only need to move the moving rod 306 to disengage the fixing rod 305 from the plug-in hole 104, thereby realizing quick installation and disassembly and improving work efficiency.

[0030] like Figure 6 As shown, the fastening assembly 4 includes a fixing cylinder 401, and a plurality of springs 402 equidistantly distributed up and down are fixedly connected to the inner wall on both sides of the fixing cylinder 401, and arc plates 403 are fixedly connected to the opposite sides of the springs 402 on both sides, and the top of the arc plates 403 is provided with an arc opening for easy plug-in, and the opposite sides of the left and right arc plates 403 are plugged with fixing columns 404, and the top of the fixing columns 404 is fixedly connected to the bottom of the mask body 101.

[0031] When the mask body 101 is installed on the mounting frame 103, the fixing column 404 at the bottom of the mask body 101 is inserted into the fixing tube 401. When the fixing column 404 is inserted, the arc plates 403 on the left and right sides are squeezed. The arc plates 403 compress the spring 2 402. Under the elastic force of the spring 2 402, the arc plates 403 tightly clamp the fixing columns 404 to achieve the tightening effect on the bottom of the mask body 101 and prevent the mask body 101 from loosening. At the same time, the arc opening at the top of the arc plate 403 that is easy to plug in also facilitates the insertion of the fixing column 404, thereby further fixing the mask body 101 and preventing it from accidentally falling.

[0032] The following is a detailed description of the working principle of the LED display mask structure.

[0033] like Figures 1-6 As shown, when in use, first move the mask body 101 close to the installation frame 103, the plug-in holes 104 on the left and right sides of the mask body 101 will contact the fixing rod 305, and the fixing rod 305 moves toward the inside of the groove 2 109 driven by the limit block 304, compressing the spring 1 303, and the telescopic rod 302 contracts. When the plug-in hole 104 moves to completely correspond to the position of the fixing rod 305, under the elastic force of the spring 1 303, the fixing rod 305 is inserted into the plug-in hole 104 to achieve the clamping fixation of the mask body 101 and the installation frame 103, and the moving rod 306 on the top of the outer wall of the limit block 304 slides on the inner wall of the rectangular groove 2 307, which plays a role in guiding and stabilizing the movement of the limit block 304. When disassembling, you only need to move the moving rod 306 to make the fixing rod 305 disengage from the plug-in hole 104, thereby achieving quick installation and disassembly and improving work efficiency.

[0034] When the mask body 101 is installed on the mounting frame 103, the fixing column 404 at the bottom of the mask body 101 is inserted into the fixing tube 401. When the fixing column 404 is inserted, the arc plates 403 on the left and right sides are squeezed. The arc plates 403 compress the spring 2 402. Under the elastic force of the spring 2 402, the arc plates 403 tightly clamp the fixing columns 404 to achieve the tightening effect on the bottom of the mask body 101 and prevent the mask body 101 from loosening. At the same time, the arc opening at the top of the arc plate 403 that is easy to plug in also facilitates the insertion of the fixing column 404, thereby further fixing the mask body 101 and preventing it from accidentally falling.

[0035] When the temperature sensor 203 detects that the temperature inside the installation frame 103 rises to a certain level, the temperature sensor 203 transmits a signal to the control device 202. The control device 202 controls the electric telescopic rod 204 to extend, thereby driving the slide bar 205 connected to the output end of the electric telescopic rod 204 to move forward along the inner wall of the chute 206. The movement of the slide bar 205 drives the cylindrical slider 210 to slide within the groove 211, thereby driving the fan blade 208 fixedly connected to the adjustment block 209 to rotate, increasing the angle of the fan blade 208, accelerating the air circulation speed, and enhancing the heat dissipation effect.

[0036] When the temperature drops to a suitable range, the electric telescopic rod 204 contracts, the slide bar 205 moves backward along the inner wall of the chute 206, and the angle of the fan blade 208 becomes smaller or even closes, thereby weakening the ventilation and heat dissipation intensity and maintaining the temperature inside the installation frame 103 to adapt to the cold weather in winter and improve the adaptability of the device.

[0037] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
