Abstract
Disclosed is a sealing ring for press-fitting connection structure, which includes a sealing ring body being annular-shaped. The sealing ring body includes an inner curved wall and an outer curved wall. At least one notch is provided and formed axially on the inner curved wall of the sealing ring body, and convex structures are provided at two lateral sides of the notch. By means of setting at least one notch in the inner arc-shaped wall of the sealing ring body, it serves as a gap between the sealing ring and the pipe for fluid to pass therethrough, achieving the purpose of warning the leakage of the press-fitting connection structure and avoiding potential use hazards in the future.
Claims11
A sealing ring for press-fitting connection structure, comprising a sealing ring body (1) being annular-shaped, wherein the sealing ring body (1) comprises an inner curved wall (11) and an outer curved wall (12), at least one notch (111) being provided on the inner curved wall (11) of the sealing ring body (1), and convex structures (13) being provided on the inner curved wall (11) and located at two opposite sides of each of the at least one notch (111), a notch wall of the at least one notch (111) being curved and concaved from the inner curved wall (11) in a direction towards the outer curved wall (12);
- wherein a diameter of the inner curved wall (11) is greater than a diameter of the outer curved wall (12);
- and
- wherein two annular and substantially flat transition portions (14) are provided between the inner curved wall (11) and the outer curved wall (12), and the inner curved wall (11) is joined to the outer curved wall (12) through the two annular and substantially flat transition portions (14).
