The utility model discloses a protective structure for the joint surface between the motor end cap and the casing, including a cylindrical casing, a motor end cap and a rubber sealing ring. A convex column is arranged at the center of the left end face of the motor end cap, which is connected with the clearance of the inner hole of the casing, and the left end face of the motor end cap is closely connected with the end face of the casing. A sealing groove and a sealing ring are arranged in the sealing groove. A first ring groove is arranged at the outer wall of the casing near the end face. A second ring groove is arranged at the outer wall of the motor end cover near the left end face. The rubber sealing ring concentric sleeve is arranged at the peripheral of the joint surface between the casing and the motor end cover, and the inner wall of the rubber sealing ring is respectively provided with a second ring groove. The first annular protrusion and the second annular protrusion which are fastened with the first annular groove and the second annular groove are simple and reasonable in structure, and the sealing property is greatly improved by sealing the joint surface of the motor end cover and the casing.
