[0022] See also Figure 1-4 The utility model provides an LED display screen that is easy to dissipate heat, including a shell 1, a display screen 2, a heat dissipation mechanism 3, a heat dissipation net 4 and a fixing mechanism 5.

The motor 301 is fixedly connected to the inner bottom surface of the shell 1, the bidirectional threaded rod 302 is connected to the output end of the motor 301, the fixed plate 303 is fixedly connected to the middle part of the bidirectional threaded rod 302, and the movable block 304 is symmetrically threadedly connected to the outside of the bidirectional threaded rod 302.

[0024] Further Figure 1 and Figure 3 As shown, it is worth to explain in detail that the slide bar 305 is fixedly connected to the inner bottom surface of the housing 1, the moving block 304 is provided with a hole adapted to the slide bar 305, and the cooling fan 306 is fixedly installed above the moving block 304;

[0025] By slidingly connecting the moving block 304 to the outside of the sliding rod 305, the moving block 304 can be restricted to rotate with the bidirectional threaded rod 302, thereby ensuring the horizontal movement of the moving block 304 and stably driving the cooling fan 306 above to move, thereby blowing the heat inside the shell 1 and accelerating the air flow rate.

[0026] According to the above working process, it can be known that: through the provided heat dissipation mechanism 3, the heat dissipation fans 306 on both sides can be driven to move toward or in the opposite direction, and the heat generated by the upper display screen 2 can be blown to accelerate the speed at which the heat flows out of the shell 1, reduce the temperature inside the shell 1, and ensure the normal operation of the display screen 2.

[0027] Further Figure 2, Figure 3 and Figure 4 As shown, it is worth specifically explaining that the fixing mechanism 5 is composed of a mounting block 501, a limiting plate 504, a positioning rod 505, a pressing plate 506 and a spring 507. The mounting block 501 is symmetrically fixedly connected to both sides of the heat dissipation net 4. The upper and lower parts of the mounting block 501 are symmetrically provided with positioning grooves 502. The bottom surface of the housing 1 is symmetrically provided with mounting grooves adapted to the mounting block 501. The upper and lower parts of the mounting grooves are symmetrically provided with rectangular grooves 503. The limiting plate 504 is slidably connected to the inside of the rectangular groove 503. Both sides of the limiting plate 504 are fixedly connected with protrusions. The inside of the rectangular groove 503 is provided with grooves adapted to the protrusions.

[0028] The provided protrusion slides inside the groove to ensure the stability of the movement of the limiting plate 504.

[0029] Further Figure 2 , Figure 3 and Figure 4 As shown, it is worth specifically explaining that the positioning rod 505 passes through the limiting plate 504 and is fixedly connected to the limiting plate 504, and one end of the positioning rod 505 extends into the interior of the installation groove, the pressing plate 506 is fixedly connected to the other end of the positioning rod 505, the spring 507 is fixedly connected between the rectangular groove 503 and the limiting plate 504, and the spring 507 is sleeved on the outside of the positioning rod 505, and the size of the positioning rod 505 is adapted to the positioning groove 502;

[0030] The spring 507 is used to elastically reset the positioning rod 505 so that the positioning rod 505 is inserted into the positioning groove 502 to fix the position of the mounting block 501 .

[0031] This solution has the following working process: when in use, the bidirectional threaded rod 302 is driven to rotate by starting the motor 301, and the moving blocks 304 on both sides are driven to move at the same time, and the cooling fan 306 is started at the same time to blow the heat inside the shell 1, accelerate the air flow, and flow out through the heat dissipation net 4, reduce the temperature inside the shell 1, and improve the normal operation speed of the display screen 2. After long-term use, the heat dissipation net 4 needs to be disassembled and cleaned, and the pressing plate 506 is pulled outward to drive the spring 507 to move, disengage from the inside of the positioning groove 502, release the fixation of the mounting block 501, and then pull out the heat dissipation net 4 to clean the heat dissipation net 4. After cleaning, the mounting block 501 is aligned with the mounting groove and inserted. After insertion, the pressing plate 506 is released, and the positioning rod 505 is driven to reset under the elastic action of the spring 507, so that the positioning rod 505 is inserted into the inside of the positioning groove 502, the position of the mounting block 501 is fixed, and the stability of the installation of the heat dissipation net 4 is ensured.

[0032] In summary: through the provided heat dissipation mechanism 3, the heat dissipation fans 306 on both sides can be driven to move toward or in opposite directions, and the heat generated by the upper display screen 2 can be blown, thereby accelerating the speed at which heat flows out of the shell 1, reducing the temperature inside the shell 1, and ensuring the normal operation of the display screen 2; through the provided fixing mechanism 5, the heat dissipation net 4 can be quickly disassembled, which is convenient for the staff to disassemble the heat dissipation net 4 for deep cleaning, thereby improving the heat dissipation effect of the heat dissipation net 4, and the heat dissipation net 4 can also be quickly installed on the back of the shell 1, thereby improving the installation speed.
