Waterproof structure of spigot type metal shell

The utility model discloses a waterproof structure of a spigot type metal shell, which comprises a shell body, an upper cover and a sealing element plugged between the shell body and the upper cover, the sealing element is made of foaming silica gel, and when the upper cover is locked to the shell body, the sealing element is extruded and deformed by the upper cover, so that a gap between the upper cover and the shell body is plugged, and the sealing element is prevented from being damaged. And external water mist and moisture are prevented from entering the shell to erode electronic components. According to the waterproof structure of the spigot type metal shell, on the premise that the appearance of a product is kept unchanged, the gap of the shell is sealed through elastic deformation of the sealing piece, the waterproof performance of the metal shell is effectively improved, the appearance and size of the product are not changed, and the requirements of customers are ingeniously met. 本实用新型公开了一种止口型金属外壳的防水结
