This utility model discloses a vulcanized rubber sealing structure, including a metal skeleton and a rubber body. One end of the metal skeleton is tapered, and the diameter of the tapered structure gradually decreases outward along the axis. The apex angle of the axial section of the tapered structure is 1. The tapered surface of the metal skeleton is provided with an annular groove perpendicular to the center along the radial direction. The rubber body is placed in the annular groove and vulcanized with the metal skeleton. The outer surface of the rubber body is a tapered structure, and the apex angle of the axial section is 2. By controlling the angle between the vulcanized rubber and the sealing surface, the vulcanized rubber sealing structure is optimized to prevent the rubber from cracking due to pressure during sealing, resulting in high reliability.
