Description

Technical Field

[0001] The utility model relates to the field of sealing rings, and specifically, to an O-ring that is not easily deformed. Background Art

[0002] An O-ring is an annular sealing element, usually made of an elastic material, used to prevent leakage of liquids or gases at the joint. O-rings are widely used in various mechanical equipment and devices, and their main function is to provide effective sealing.

[0003] If the O-ring is deformed too much or undergoes permanent deformation, its sealing surface may no longer be able to maintain close contact, resulting in sealing failure. Such failure may cause fluid leakage, which in turn may cause equipment damage or system failure. Therefore, an O-ring that is not easily deformed is needed.

[0004] For example, Chinese Patent No. 202221407217.0 discloses an O-ring that is not easily deformed, which includes a first connecting rod, a telescopic rod, a second connecting rod, and a third spring. The first connecting rod and the second connecting rod play a supporting role, and the elastic force of the third spring is very large and is not easily compressed. However, the above O-ring has the following disadvantages: the design of multiple springs and connecting rods forms a relatively complex structure, increasing the manufacturing difficulty and may also lead to more failure points in actual applications.

[0005] Regarding the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

[0009] Furthermore, in order to provide multiple sealing points on the inner wall, the first sealing body includes a first sealing ring provided on the inner wall of the deformation-resistant main body. A number of first sealing lips are provided on the inner wall of the first sealing ring, and a first connection block is provided on the outer wall of the first sealing ring and located within the first connection groove; the width of the first connection block and the first connection groove gradually decreases in the direction close to the center of the deformation-resistant main body.

[0010] Further, in order to provide multiple sealing points on the outer wall, the second sealing body includes a second sealing ring disposed on the outer wall of the anti-deformation main body. A plurality of second sealing lips are provided on the outer wall of the second sealing ring, and a second connecting block is disposed on the inner wall of the second sealing ring and within the second connecting groove; the width of the second connecting block and the second connecting groove gradually increases in the direction closer to the center of the anti-deformation main body.

[0011] Further, in order to ensure the reliability and stability of the connection of each component, a plurality of first connecting grooves and second connecting grooves are arranged alternately in the circumferential direction of the anti-deformation main body.
