An air outlet blade is provided on the outer surface of the air outlet fan, and the air outlet blade is rotatably connected to the air outlet fan. In the prior art, excessively high temperature will cause bulging on the outer surface of the LED display screen. When the operating temperature of the LED display screen exceeds the bearing temperature of the chip, the luminous efficiency of the LED display screen will decrease rapidly, resulting in obvious light decay, and in the case of serious damage, the display screen will be completely destroyed. To address such problems, the utility model adopts a heat dissipation structure provided on the back of the device frame, that is, the external cold air is sent into the air inlet duct through the air supply fan, and then flows from the inside of the air inlet duct to the rear air outlet duct. At this time, the air outlet fan arranged at the end of the air outlet duct starts to operate due to the wind force, so that negative pressure is generated in the air outlet duct, resulting in faster air circulation, thereby reducing the heat inside the device frame, thereby improving the heat dissipation efficiency inside the LED display screen.

[0006] Preferably, a plurality of square grooves are opened between the device frame and the LED display screen, and buffer blocks are provided inside the plurality of square grooves. The size of the plurality of buffer blocks is consistent with that of the square grooves, and the plurality of buffer blocks are fixedly connected to the device frame. In the prior art, a device frame is installed on the side of most LED display screens to avoid wear of the LED display screen, and to ensure that the display screen and the device frame are reasonably matched.

To address this problem, the utility model adopts a plurality of square grooves between the device frame and the LED display screen, and buffer blocks are arranged in the square grooves. The buffer blocks tightly combine the two to ensure that shaking is avoided during the movement.
