[0033] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0034] Example 1: An anti-aging Y-shaped rubber seal ring, see Figures 1 to 5 , comprising a Y-shaped sealing ring body 1 and a connecting structure 2;

[0035] The connection structure 2 is arranged on the closed side of the Y-shaped sealing ring body 1;

[0036] The connection structure 2 includes an annular plate A 201, an annular plate B 202 and a clamping ring 203;

[0037] The annular plate A201 is bonded to the closed side of the Y-type sealing ring body 1; the annular plate B202 is fixed on the inner side of the annular plate A201; wherein the inner ring side of the annular plate B202 is bonded to the outer ring wall of the Y-type sealing ring body 1; the retaining ring 203 is fixed on the inner ring side of the annular plate B202; wherein the retaining ring 203 is embedded and bonded to the annular groove 101 opened on the outer ring wall of the Y-type sealing ring body 1.

[0038] The utility model has the advantages of arranging an annular plate A201, an annular plate B202, a snap ring 203 and an annular groove 101, and the snap ring 203 is embedded in the annular groove 101 and bonded, thereby strengthening the stability of the connection between the annular plate A201 and the closed side of the Y-shaped sealing ring body 1, thereby solving the problem that the connection between the closed side of the Y-shaped sealing ring and the connecting ring is easily loose due to the full force acting on the connection for a long time.

[0039] Specifically, the annular groove 101 is composed of an outer annular groove 1011 and an inner annular groove 1012 , and the inner annular groove 1012 is arranged on one side of the inner bottom wall of the outer annular groove 1011 ; wherein an annular spring piece 204 is arranged at the bottom of one side of the retaining ring 203 , and the annular spring piece 204 abuts and cooperates with the inner annular groove 1012 .

[0040] The utility model provides the inner annular groove 1012 and the annular spring piece 204 , so that after the clamping ring 203 is embedded in the annular groove 101 , the annular spring piece 204 is clamped in the annular spring piece 204 , and the connection stability is enhanced by positioning the annular spring piece 204 .

[0041] Furthermore, the annular spring piece 204 adopts an arc-shaped structural design, and the arched end of the annular spring piece 204 faces inward; wherein, one end of the annular spring piece 204 is fixedly connected to the bottom of one side of the retaining ring 203, and the other end of the annular spring piece 204 abuts against the outer ring wall of the inner ring groove 1012; after the arc-shaped annular spring piece 204 is clamped in the inner ring groove 1012, the annular spring piece 204 forms a supporting surface with an arched cross-section, which has a better stabilizing effect.

[0042] Furthermore, the retaining ring 203 is composed of an outer ring 2031 and an inner ring 2032, and the two sides of the outer ring 2031 are respectively in contact with the two sides of the outer ring groove 1011; wherein, the width of the inner ring 2032 is smaller than the width of the outer ring 2031; the setting of the inner ring 2032 provides a concave space, providing space for the annular spring piece 204 to be squeezed and bent.
