Document Type and Number:
WIPO Patent Application WO/2023/231847
Kind Code:
A1
Abstract:
A sealing ring (2), comprising: a sealing body (21), at least a portion of the sealing body (21) extending outward in the radial direction of the sealing ring (2); a positioning portion (22), connected to the sealing body (21) in the axial direction of the sealing ring (2), at least a portion of the positioning portion (22) extending outward in the radial direction of the sealing ring (2); the inner diameter of the positioning portion (22) being less than the inner diameter of the sealing body (21); and an annular skeleton (23), located in the positioning portion (22). The sealing body extending outward in the radial direction of the sealing ring enhances the sealing effect of the sealing ring; the positioning portion extending outward in the radial direction of the sealing ring reduces the possibility of rolling or sliding of the sealing ring, thus improving the sealing effect; the annular skeleton increases the positioning reliability of the sealing body, and realizes the sealing between the sealing body and a socket.
