[0033] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0034] Refer to Figures 1-3This utility model provides an embodiment of a liquid crystal display screen structure that facilitates heat dissipation. It includes a support column 6, with a liquid crystal display screen body 1 fixedly connected to the top of the support column 6. A heat dissipation component is slidably connected to the side of the liquid crystal display screen body 1 for heat dissipation. A support component is slidably connected to the outer periphery of the support column 6 for supporting the device. The heat dissipation component includes a metal plate 3, which is slidably connected to the side of the liquid crystal display screen body 1. The metal plate 3 promotes air circulation and removes some of the heat generated by the display screen during operation. A fan 5 is slidably connected inside the metal plate 3, introducing cool air to the liquid crystal screen under the action of the fan 5, improving the heat dissipation effect. A heat sink 4 is fixedly connected inside the metal plate 3, which conducts heat to the heat source, further improving the heat dissipation effect of the liquid crystal display screen. A disassembly component is installed inside the metal plate 3.

[0035] Reference Figure 1 and Figure 3 The disassembly assembly includes a connecting rod 12, which is slidably connected inside the metal plate 3. One end of the connecting rod 12 is fixedly connected to a locking block 10. Moving the connecting rod 12 causes the locking block 10 to move accordingly, engaging with the interior of the LCD screen body 1. Thus, the connecting rod 12 causes the locking block 10 to engage and disengage from the interior of the LCD screen body 1. A spring 11 is fixedly connected inside the metal plate 3, with one end of the spring fixedly connected to the side of the locking block 10. The movement of the locking block 10... When the spring 11 is compressed, it will contract under force. The outer circumference of the connecting rod 12 is rotatably connected to the knob 9. The side of the LCD screen body 1 is fixedly connected to the fixing block 2. The inside of the fixing block 2 is slidably connected to the side of the metal plate 3. By turning the knob 9, the connecting rod 12 can be moved, thereby disengaging the metal plate 3 from the inside of the LCD screen body 1 through the locking block 10, making it easier to clean the dust on the metal plate 3 and ensuring the heat dissipation effect of the metal plate 3.

[0036] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6The support assembly includes a base 7, the interior of which is slidably connected to the outer periphery of the support column 6. An anti-slip block 8 is fixedly connected to the bottom of the base 7, increasing the friction and stability of the base 7. A second knob 18 is rotatably connected inside the fan 5, and a pull rope 17 is fixedly connected inside the knob 18. Rotating the knob 18 causes the pull rope 17 to retract. Two locking blocks 15 are fixedly connected to both ends of the pull rope 17. Retracting the pull rope 17 moves the locking blocks 15. A second spring 16 is fixedly connected to the side of the locking blocks 15. When the locking blocks 15 move into the fan 5, they compress the springs 16, causing them to contract. A slot 14 is formed inside the metal plate 3, and the slot 14 connects to the locking blocks. The two blocks 15 are interlocked, but when the two blocks 15 move into the inside of the fan 5, the two blocks 15 will disengage from the slot 14, so that the fan 5 can be disassembled. Similarly, during installation, under the tension of the spring 16 returning to its original position, the two blocks 15 are interlocked with the slot 14, so that the fan 5 can be installed, thus facilitating the maintenance and replacement of the fan 5. The heat sink 4 is made of copper and has multiple pieces located at the ventilation openings of the metal plate 3, thereby improving the heat conduction effect of the heat sink 4. There are four fans 5, and the four fans 5 work independently. The fans 5 are controlled by the temperature sensor inside the LCD display body 1. By detecting the temperature, the number of fans 5 working is controlled, thereby ensuring the heat dissipation effect while reducing energy consumption.

[0037] Working principle: First, when dissipating heat from the LCD screen body 1, the metal plate 3 will work, increasing the airflow between the LCD screen body 1 and the airflow, and the fan 5 will blow external cold air into the screen to improve the heat dissipation effect. At the same time, the copper heat sink 4 can quickly conduct heat away, effectively reducing the temperature of the LCD screen body 1. Second, when it is necessary to clean the dust from the metal plate 3, by turning the knob 9, the connecting rod 12 will move. When passing through, the spring 11 will be compressed, which will cause the locking block 10 to disengage from the interior of the LCD screen body 1 through the connecting rod 12. This allows the metal plate 3 to be directly pulled out from the interior of the fixing block 2, making it convenient for staff to clean the dust from the metal plate 3 and ensuring good heat dissipation of the metal plate 3.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
