[0030] To solve this problem, the first embodiment of the utility model provides a sealing ring. By arranging two support rings 110 on the inner circumferential wall of the annular body 100, and arranging a support protrusion in the middle of the outer circumferential wall of the annular body 100, the two support rings 110 cooperate with the support platform to form a triangular force-bearing structure, which is beneficial to enhancing the structural strength of the sealing ring, reducing the deformation of the sealing ring when it is affected by gravity, and preventing the sealing ring from being deformed by gravity and detaching from the installation groove 210 during installation. The specific structure and function of the sealing ring provided by the embodiment of the utility model will be further explained in combination with text and drawings.

During assembly, the sealing ring is first installed in the mounting groove 210 of the hub shell, and then the hub cover 220 is installed on the hub shell. When the hub cover 220 is connected to the hub shell, pressure is generated on the sealing ring, and the sealing ring will be deformed after being compressed. The ribs 130 on the two side walls of the sealing ring can abut against the side walls of the mounting groove 210, which is beneficial to increase the friction between the sealing ring and the inner wall of the mounting groove 210, realize the self-locking of the sealing ring, and can prevent the sealing ring from detaching from the mounting groove 210 during the installation process.
