Guangxiang Technology obtained patents for sealing rings and LED displays, improving the sealing performance of LED displays

The patent abstract shows that the present invention provides a sealing ring, including a ring body, which includes an annular groove. The upper and lower surfaces of the bottom wall of the annular groove are provided with first convex rings. The first convex ring is a closed ring that extends in the same direction as the annular groove. In the sealing ring provided by the invention, the side wall of the annular groove has the effect of reducing the impact force of moisture. The pressure between the first convex ring and the sealed body increases, thereby improving the sealing performance of the first convex ring. The present invention also provides an LED display screen, which includes a module, a box, a power box and a plurality of sealing rings mentioned in the above technical solution. The sealing ring provided between the power box and the box is a first sealing rubber ring, and the sealing ring provided between the box and the module is a second sealing rubber ring. In the LED display screen provided by the invention, the first sealing rubber ring and the second sealing rubber ring have good sealing performance, which improves the sealing performance of the LED display screen.
