The utility model solves the technical problems by adopting the technical scheme that: the utility model provides a rubber seal, includes the rubber circle body, this internal annular cavity that is provided with of rubber circle, the medial surface of rubber circle body still is provided with the annular opening with intercommunication annular cavity, annular opening's bilateral symmetry is provided with annular sealing strip, two sealing strip one end is connected with annular opening one side inner wall integration, and the other end is located annular cavity and two the outer wall face of sealing strip sets up relatively from top to bottom, two set up respectively to be equipped with an O type sealing washer between the inner wall face of sealing strip and the annular cavity, fixedly connected with is used for sealing annular opening's U type sealing washer between two O type sealing washer.

Further perfecting, a plurality of raised elastic reinforcing ribs are circumferentially distributed on the inner wall of the annular cavity facing one side of the annular opening.

Further perfecting, the outer side surface of the U-shaped sealing ring is provided with positioning convex points, and the positioning convex points are positioned between adjacent elastic reinforcing ribs.

Further perfecting, the U-shaped sealing ring is provided with an annular mounting groove for adhesively fixing the O-shaped sealing ring.

Further perfecting, the inner side surface of the U-shaped sealing ring is provided with annular friction lines which are axially distributed.

The beneficial effects of the utility model are as follows: compared with the prior art, the sealing strip and the O-shaped sealing ring are matched to adjust the width of the annular opening, so that the sealing strip can be matched with annular parts with the same diameter but different thicknesses, the rubber ring can be tightly connected with the parts to ensure the tightness in use, the sealing strip is simple in structure and convenient to assemble, the clamping force on the annular opening can be improved through the U-shaped sealing ring, the function of a gasket is achieved, and the service life of the rubber ring body is prolonged.

Detailed Description

The utility model is further described below with reference to the accompanying drawings:

Referring to fig. 1: the rubber sealing ring comprises a rubber ring body 1, an annular cavity 2 is arranged in the rubber ring body 1, an annular opening 3 communicated with the annular cavity 2 is further formed in the inner side surface of the rubber ring body 1, annular sealing strips 4 are symmetrically arranged on two sides of the annular opening 3, one end of each sealing strip 4 is integrally connected with one side inner wall of the annular opening 3, the other end of each sealing strip is located in the annular cavity 2, the two sealing strips 4 are oppositely arranged up and down on the outer wall surface of each sealing strip 4, O-shaped sealing rings 5 are respectively arranged between the inner wall surface of each sealing strip 4 and the annular cavity 2, and U-shaped sealing rings 6 used for sealing the annular opening 3 are fixedly connected between the two O-shaped sealing rings 5.

As shown in fig. 2, when the part is inserted into the annular opening 3 of the rubber ring body 1, the sealing strips 4 positioned on the upper side and the lower side of the annular opening 3 are extruded towards the inner side of the annular cavity 2 by the edge of the part, so that the O-shaped sealing ring 5 is elastically deformed, the two sealing strips 4 clamp the part, the sealing effect of the sealing rubber ring is improved, the sealing rubber ring is suitable for parts with different specifications and thicknesses, and the practicability of the sealing rubber ring is improved. The U-shaped sealing ring 6 plays a role in positioning the O-shaped sealing ring 5, improves the elasticity of the rubber ring body 1, avoids excessive deformation of the annular opening 3, can avoid gaps and looseness between parts and the sealing ring body due to the fact that the U-shaped sealing ring 6 plays a role in filling the annular cavity 2, and can adjust the width of the annular opening through the cooperation of the sealing strip and the O-shaped sealing ring when the diameters of the parts are unchanged and the thicknesses of the edges are different, so that the sealing strip can be adapted to annular parts with the same diameters but different thicknesses.

The annular cavity 2 is provided with a plurality of raised elastic reinforcing ribs 7 circumferentially distributed on the inner wall of one side of the annular opening 3, so that the structural strength of the rubber ring body 1 can be improved, and the elastic supporting effect on the U-shaped sealing ring 6 is achieved.

The outer side surface of the U-shaped sealing ring 6 is provided with the positioning protruding points 10, and the positioning protruding points 10 are positioned between adjacent elastic reinforcing ribs, so that circumferential rotation between the U-shaped sealing ring 6 and the rubber ring body 1 can be limited, and abrasion is reduced.

The U-shaped sealing ring 6 is provided with an annular mounting groove 8 for fixedly adhering the O-shaped sealing ring 5, so that the O-shaped sealing ring 5 can be firmly positioned and stably axially deformed.

The inner side surface of the U-shaped sealing ring 6 is provided with annular friction lines 9 which are axially distributed, so that the axial static friction force between the U-shaped sealing ring and the part can be enhanced, and slipping between the U-shaped sealing ring and the part during movement is avoided.
