Sliding cover type waterproof device

The invention relates to a sliding cover type waterproof device which comprises a shell and a cover plate, the shell is provided with a groove, the cover plate is supported, installed and matched in the groove, sliding grooves are formed in the two sides of the groove respectively, and small cylinders are arranged at the heads of the two side faces of the cover plate respectively. The small cylinders on the two side faces of the cover plate are supported to slide in the sliding grooves of the shell so that the cover plate can be connected with the shell. By the adoption of the sliding cover type waterproof device, the waterproof requirement of a product is met, the space occupied by the waterproof structure at the connector is reduced, the situation that a flip cover type structure hinders the use of the product by using an upper cover plate is avoided, other structures can meet the design requirement in a limited area, and the product quality is improved. And meanwhile, the whole product is more attractive i
