Wear-resistant structure of wear-resistant fan

The wear-resistant structure of the wear-resistant draught fan comprises a machine shell, a metal layer is arranged on the outer surface of the machine shell, two first transverse rods are fixedly installed on the outer surface of the metal layer, the lower ends of the two first transverse rods are located on the same plane, and the metal layer is located between the two first transverse rods. A sliding block is fixedly installed on the outer wall of the side, away from the metal layer, of the first transverse rod, a protective shell is arranged on the outer surface of the metal layer, a groove is formed in the inner surface of the protective shell, a waterproof shell is fixedly installed on the outer surface of the protective shell, and a plurality of protrusions are vertically and fixedly installed on the outer surface of the waterproof shell. According to the utility model, the interior of the fan can be effectively buffered, so that the stability of the fan in use is improved through shock absorption trea
