[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Specific examples are given below.

[0027] See also Figure 1 - Figure 6 The utility model provides a liquid crystal display protective back plate, comprising a back plate body 1, wherein the side wall of the back plate body 1 is provided with a plurality of heat dissipation holes 11; the heat dissipation holes 11 are symmetrically arranged; the inner side wall of the back plate body 1 is provided with a fixing frame 12; the inner side wall of the fixing frame 12 is fixedly connected with a fixing plate 13; the inner side wall of the fixing plate 13 is fixedly connected with a plurality of fans 14; the inner side wall of the back plate body 1 is provided with a radiator 15; the side wall of the back plate body 1 is provided with a fixing hole 16. When the display is in operation, the backlight of the display will generate a lot of heat, and the air inside the display The space is relatively narrow, which leads to internal heat accumulation, thus causing the display to burn out. The fan 14 arranged at the heat dissipation hole 11 allows air to be sucked into the back panel body 1 from the bottom heat dissipation hole 11, and then blown to the radiator 15. The radiator 15 is in contact with the display back panel, thereby increasing the heat dissipation effect. The fan 14 blows air to the radiator 15, and then exhausts it from the top of the back panel body 1, thereby performing a layered circulation, thereby effectively reducing the operating temperature inside the display and reducing the heat accumulation on the display back panel, thereby increasing the service life of the display.

[0028] Further, such as Figure 3 , Figure 4 and Figure 5As shown, the inner wall of the back panel body 1 has two pairs of fixing columns 2; the inner wall of the fixing column 2 is provided with a sliding groove 21; the inner wall of the sliding groove 21 is fixedly connected with a spring 22; the inner wall of the sliding groove 21 is slidably connected with a connecting rod 23; the end of the connecting rod 23 is fixedly connected with a radiator 15. During operation, when the back panel body 1 is fixed to the other half of the shell of the display, the radiator 15 will contact the back panel of the liquid crystal display, thereby squeezing the spring 22. When the spring 22 is squeezed, a reaction force will be generated, thereby pushing the radiator 15 to contact the back panel of the liquid crystal display, so that the heat generated by the display during operation is transferred to the radiator 15. By setting the squeezing device, the contact effect between the radiator 15 and the back panel of the display is effectively improved, thereby increasing the heat dissipation effect of the radiator 15, thereby reducing the temperature of the display during operation and improving the service life of the display.

[0029] Further, such as Figure 4 and Figure 6 As shown, a pair of limit blocks 3 are fixedly connected to the inner wall of the back plate body 1; a groove 31 is provided on the inner wall of the limit block 3; a sliding fixing pin 32 is slidably connected to the inner wall of the groove 31; a card slot 33 is provided on the side wall of the fixed frame 12; and a strong magnet 34 is fixedly connected to the inner wall of the card slot 33. During operation, when installing the fixed frame 12, the staff clamps the fixed frame 12 between the pair of limit blocks 3. When the fixed frame 12 is placed on the top of the limit block 3 and the fixed frame 12 is pressed downward, the fixed frame 12 will squeeze the sliding fixing pin 32 into the groove 31. Since the sliding fixing pin 32 is made of metal, when the fixed frame 12 is completely pressed to contact the inner wall of the back plate body 1, the magnetic force of the card slot 33 will suck the sliding fixing pin 32 into the card slot 33, thereby fixing the fixed frame 12 between the pair of limit blocks 3. This step effectively simplifies the installation steps of the fixed frame 12 by the staff, thereby reducing the difficulty of installing the equipment.

[0030] Further, such as Figure 4 and Figure 6 As shown, a connecting rope 4 is provided at the end of the sliding fixing pin 32; the connecting rope 4 is fixedly connected to the end of the sliding fixing pin 32; a holding ball 41 is fixedly connected to the end of the connecting rope 4. During operation, when it is necessary to disassemble the fixing frame 12, the staff pulls the holding ball 41 to disengage the sliding fixing pin 32 from the inside of the card slot 33, and then the fixing frame 12 can be taken out from between a pair of limit blocks 3, so as to facilitate the staff to disassemble and replace the equipment, reduce the workload of the staff during disassembly, and facilitate the staff to maintain and replace the equipment.

[0031] Further, such as Figure 2As shown, a pair of limit frames 5 are fixedly connected to the side wall of the back panel body 1; the inner wall of the limit frame 5 is slidably connected with a filter 51. When working, the filter 51 arranged at the heat dissipation hole 11 at the bottom effectively reduces the content of dust and impurities when the air enters the back panel body 1, thereby reducing the accumulation of dust and impurities inside the back panel body 1, thereby improving the heat dissipation effect of the equipment, thereby effectively increasing the flow of air and reducing the smoothness of the equipment during operation.

[0032] Further, such as Figure 1 and Figure 4 As shown, a rotating limit button 6 is provided on the top of the limit block 3; the rotating limit button 6 is rotatably connected to the top of the limit block 3. During operation, after the fixed frame 12 is clamped between a pair of limit blocks 3, the staff rotates the limit button 6 so that the protruding end of the rotating limit button 6 is pressed on the top of the fixed frame 12, thereby limiting the fixed frame 12 to a certain extent, thereby effectively increasing the stability of the equipment and reducing the possibility of the equipment falling off.

[0033] Further, such as Figure 1 and Figure 4 As shown, the side wall of the radiator 15 is provided with a heat dissipation silicone sheet 7; the heat dissipation silicone sheet 7 is fixedly connected to the side wall of the radiator 15. When working, by providing the heat dissipation silicone sheet 7 on the side wall of the radiator 15, the heat dissipation silicone sheet 7 can be more closely fitted to the back plate of the display, thereby effectively increasing the contact area between the back plate of the display and the heat dissipation silicone sheet 7, thereby improving the heat transfer effect, and thereby effectively reducing the operating temperature of the display.

[0034] Working principle: When the display is running, the backlight of the display will generate a lot of heat, and the internal space of the display is relatively small, which leads to internal heat accumulation, thereby causing the display to burn out. The fan 14 set at the heat dissipation hole 11 allows air to be sucked into the back panel body 1 from the bottom heat dissipation hole 11, and then blown to the radiator 15, and the radiator 15 is in contact with the back panel of the display to increase the heat dissipation effect. The fan 14 blows air to the radiator 15, and then exhausts it from the top of the back panel body 1, thereby performing a layered circulation, thereby effectively reducing the operating temperature inside the display and reducing the heat accumulation of the display back panel, thereby increasing the service life of the display. When the back panel body 1 is fixed to the other half of the shell of the display , the radiator 15 will contact the back plate of the liquid crystal display, thereby squeezing the spring 22. When the spring 22 is squeezed, a reaction force will be generated, thereby pushing the radiator 15 to contact the back plate of the liquid crystal display, so that the heat generated by the display during operation is transferred to the radiator 15. The extrusion device is set to effectively improve the contact effect between the radiator 15 and the back plate of the display, thereby increasing the heat dissipation effect of the radiator 15, thereby reducing the temperature of the display during operation and improving the service life of the display. When installing the fixing frame 12, the staff clamps the fixing frame 12 between a pair of limit blocks 3. When the fixing frame 12 is placed on the top of the limit block 3 and the fixing frame 12 is pressed downward, the fixing frame 12 will slide the fixing pin 32 The fixing pin 32 is squeezed into the groove 31. Since the sliding fixing pin 32 is made of metal, when the fixing frame 12 is fully pressed to contact the inner wall of the back plate body 1, the magnetic force of the slot 33 will suck the sliding fixing pin 32 into the slot 33, thereby fixing the fixing frame 12 between a pair of limit blocks 3. This step effectively simplifies the installation steps of the fixing frame 12 by the staff, thereby reducing the difficulty of installing the equipment. When it is necessary to remove the fixing frame 12, the staff pulls the holding ball 41 to disengage the sliding fixing pin 32 from the slot 33, and then the fixing frame 12 can be taken out from between the pair of limit blocks 3, thereby facilitating the staff to disassemble and replace the equipment, reducing the workload of the staff during disassembly, and facilitating the staff to maintain the equipment. Protection replacement, through the filter 51 set at the heat dissipation hole 11 at the bottom, the dust and impurity content of the air when entering the back panel body 1 is effectively reduced, thereby reducing the accumulation of dust and impurities inside the back panel body 1, thereby improving the heat dissipation effect of the equipment, thereby effectively increasing the flow of air, and at the same time reducing the smoothness of the equipment during operation, and then the fixed frame 12 is stuck between a pair of limit blocks 3, and the staff turns the limit button 6 so that the protruding end of the limit button 6 is pressed on the top of the fixed frame 12, so as to limit the fixed frame 12 to a certain extent, thereby effectively increasing the stability of the equipment and reducing the situation of the equipment falling off, and the heat dissipation silicone sheet 7 is provided on the side wall of the radiator 15, so that the heat dissipation silicone sheet 7 can be more closely attached to the back panel of the display,This effectively increases the contact area between the display back plate and the heat dissipation silicone sheet 7, thereby improving the heat transfer effect, and effectively reducing the operating temperature of the display.
