| description | The invention discloses a waterproof structure. The waterproof structure comprises a basket body (10), a through hole (10a), a rotating shaft (20), and a flange portion (30), wherein the through hole (10a) is formed in the basket body (10), the rotating shaft (20) is inserted into the through hole (10a) in a penetrating mode and rotates freely in the through hole (10a), the flange portion (30) is arranged on the outer side of the basket body (10) and fixed on the rotating shaft (20) and rotates along with the rotating shaft (20). A gap (g2) is formed between the outer side of the basket body (10) and the flange portion (30), and a labyrinth structure is axially arranged in the gap (g2). Furthermore, the labyrinth structure comprises a plurality of annular concave portions and convex portions, wherein the concave portions and the convex portions are arranged on the side, provided with the gap (g2), of the basket body (10) and the centers of the annular concave portions and convex portions and the axis of the r |
