At the same time, when the limit rod 202 slides, the pressure plate 210 on the limit rod 202 squeezes the air cushion 209, so that the gas enters the inside of the sealing ring 201, and the outside of the sealing ring 201 expands to have a better sealing effect, and the heat sink 302 It is detachably mounted on the back side of the LED display screen body 1, which is beneficial to absorbing and releasing the heat generated by the LED display screen body 1. Through the rotation of the fan 301, the fan 301 blows air to the inside of the fixed shell 305. Since the fixed shell 305 is a trapezoidal structure, the airflow blown by the fan 301 is well guided out laterally, and the airflow enters the heat sink 302 through the filter 304 for heat dissipation, and through the "L"-shaped guide groove 306 on the heat sink 302, the airflow can change direction and diffuse outward, so that the heat dissipation area is increased and the overall heat dissipation effect is better. The filter 304 is beneficial to filtering dust and debris, preventing the heat sink 302 from being blocked and causing pollution to the LED display screen body 1. By removing the filter 304, cleaning and maintenance are convenient.
