The fixed plate is rotatably connected to the second bevel gear 9, and a cam 10 is fixedly connected to the outer side of the second bevel gear 9, and a sliding shaft is fixedly connected to the outer side of the cam 10. The inner wall of the heat dissipation cover 2 is rotatably connected to both sides of the second bevel gear 9, and the outer side of the fan gear 11 is fixedly connected to a limit plate 12, and the sliding shaft is slidably connected to the inside of the limit plate 12. One end of the two rotating rods 13 close to the fan gear 11 is fixedly connected to a transmission gear 14, and the transmission gear 14 is meshed with the corresponding fan gear 11. A transmission assembly is provided inside the heat dissipation cover 2.

[0021] Specifically, the transmission assembly includes a motor 7, which is fixedly connected to the upper outer side of the billboard body 1, and the outside of the output end of the motor 7 is fixedly connected to a first pulley 15, and the outsides of the two rotating rods 13 are fixedly connected to second pulleys 16, and the two second pulleys 16 are respectively connected to the first pulley 15 through two transmission belts 17. The output end of the motor 7 extends to one side of the interior of the heat dissipation cover 2 and is fixedly connected to a first bevel gear 8, and the first bevel gear 8 is respectively meshed with the two second bevel gears 9.

[0022] Through the above technical solution, the motor 7 is started by an external controller, and the output end of the motor 7 drives the first pulley 15 to rotate. The first pulley 15 then drives the second pulley 16 and the corresponding rotating column 4 to rotate through the transmission belt 17, so that the rotating column 4 drives the fan 5 to rotate, and the fan 5 can quickly discharge the hot air emitted by the billboard body 1 through the heat dissipation groove 3 to the outside of the heat dissipation cover 2. At the same time, the output end of the motor 7 can drive the first bevel gear 8 to rotate, and the first bevel gear 8 then drives the second bevel gears 9 on both sides to rotate through the meshing relationship, so that the second bevel gear 9 drives the cam 10 to rotate, and the cam 10 can drive the cam 10 to rotate during the rotation process. The movable sliding shaft slides inside the limit plate 12, thereby driving the sector gear 11 to swing back and forth through the limit plate 12, and the sector gear 11 can drive the transmission gear 14 to rotate back and forth through the meshing relationship. The transmission gear 14 then drives the corresponding first swing piece 6 to swing continuously through the rotating rod 13, thereby accelerating the circulation of hot gas. The device can quickly discharge the hot air inside the billboard body 1 through the continuously rotating fan 5, and cooperate with the continuously swinging first swing piece 6 to accelerate the circulation of hot gas, thereby improving the heat dissipation speed of the hot air, thereby improving the heat dissipation effect and heat dissipation efficiency of the billboard body 1.

[0023] Specifically, the diameter of the first pulley 15 is greater than the diameter of the two second pulleys 16, and the second swing piece 18 is symmetrically connected to the lower part of the inner part of the air outlet. The outer sides of the second swing piece 18 are both connected to the connecting rod 19, and the top of the connecting rod 19 is connected to the first swing piece 6.

[0024] Through the above technical solution, during the repeated swinging of the first swinging piece 6, the connecting rod 19 can drive the corresponding second swinging piece 18 below to swing accordingly, forming two sets of heat dissipation channels, thereby further improving the heat dissipation efficiency.

[0026] Through the above technical solution, the staff can quickly control the motor 7 through an external controller, and the filter can effectively prevent dust in the external air from entering the interior of the billboard body 1 through the heat dissipation groove 3, thereby improving the service life of the electrical parts inside the billboard body 1.

[0027] When in use, the motor 7 is started through an external controller, and the output end of the motor 7 drives the first pulley 15 to rotate, and the first pulley 15 then drives the second pulley 16 and the corresponding rotating column 4 to rotate through the transmission belt 17, so that the rotating column 4 drives the fan 5 to rotate, and the fan 5 can quickly discharge the hot air emitted by the billboard body 1 through the heat dissipation groove 3 to the outside of the heat dissipation cover 2. At the same time, the output end of the motor 7 can drive the first bevel gear 8 to rotate, and the first bevel gear 8 then drives the second bevel gears 9 on both sides to rotate through the meshing relationship, so that the second bevel gear 9 drives the cam 10 to rotate. During the rotation process, the cam 10 can drive the sliding shaft to slide inside the limit plate 12, thereby driving the fan gear 11 to swing back and forth through the limit plate 12, and the transmission gear 14 can be driven to reciprocate through the meshing relationship of the fan gear 11. 14 then drives the corresponding first swing piece 6 to continuously swing through the rotating rod 13, thereby accelerating the circulation of hot gas. The device can quickly discharge the hot air inside the billboard body 1 through the continuously rotating fan 5, and cooperate with the continuously swinging first swing piece 6 to accelerate the circulation of hot gas, thereby improving the speed of heat dissipation, thereby improving the heat dissipation effect and heat dissipation efficiency of the billboard body 1. During the repeated swinging of the first swing piece 6, the corresponding second swing piece 18 below can be driven to swing along through the connecting rod 19 to form two sets of heat dissipation channels, thereby further improving the heat dissipation efficiency. The external controller can facilitate the staff to quickly control the motor 7.
