Description

Technical Field

[0001] This utility model relates to the field of sealing ring technology, specifically a compression rubber sealing ring. Background Technology

[0002] Extrusion-type rubber seals are a common sealing element. They rely on their own elastic deformation to tightly adhere to the gap between the sealing mating surfaces, cutting off or increasing the resistance of the leakage channel to achieve a sealing function. However, when existing extrusion-type seals are used, although the seals will deform under compression, the direction of deformation is uncontrollable, which can easily cause sealing leakage. In addition, the surface of existing seals is smooth, and in dynamic sealing scenarios, friction can easily cause the seals to shift, affecting the sealing stability. To solve the above problems, an extrusion-type rubber seal is needed.

[0003] An existing extrusion-type rubber seal ring cannot resist friction during operation in dynamic sealing scenarios, causing the seal ring to shift and affecting sealing stability. When the seal ring is compressed, the deformation direction is uncontrollable, which can easily cause sealing leakage. Therefore, there is an urgent need for an extrusion-type rubber seal ring. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a compression rubber sealing ring to solve the problems of existing compression rubber sealing rings being unable to resist friction during use in dynamic sealing scenarios, resulting in sealing ring displacement and affecting sealing stability, and the sealing ring's deformation direction being uncontrollable when compressed, which easily leads to sealing leakage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a compression rubber sealing ring, comprising a ring body, a protrusion installed at the bottom of the ring body, an extrusion groove formed inside the ring body, a ring head installed at the top of the ring body, and a deformation groove formed on the inner sidewall of the ring head.

[0006] Preferably, the ring body is arranged in a rectangular ring shape, and the protrusions are arranged in a ring array with the central axis of the ring body as the center.

[0007] Preferably, the extrusion groove is located at the center of the ring body and is diamond-shaped.

[0008] Preferably, the ring head is bonded to the ring body, and the top of the ring head is cone-shaped.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. This utility model features a ring body and protrusions. The protrusions are arranged in a ring array around the central axis of the ring body. In dynamic sealing applications, the protrusions increase the friction between the sealing ring and the mating surface, preventing the sealing ring from shifting and improving its stability.

[0011] 2. This utility model features an extrusion groove, a ring head, and a deformation groove. The extrusion groove is diamond-shaped. When the ring body is compressed, the two sides of the extrusion groove deform outward, causing the inner and outer sides of the ring body to extend outward and closely fit the gap of the sealing coupling surface. This prevents uneven stress on the ring body and avoids deformation to only one side. At the same time, the deformation groove reduces local stress concentration on the sealing surface, preventing the ring head from cracking due to excessive compression. It also ensures uniform contact pressure distribution and improves sealing reliability. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0017] The embodiments of this utility model will be described below based on its overall structure.

[0018] Please see Figures 1-3 A compression-type rubber sealing ring includes a ring body 1, with protrusions 2 installed at the bottom of the ring body 1. The ring body 1 is rectangular and the protrusions 2 are arranged in a ring array around the central axis of the ring body 1. Through the arrangement of the ring body 1 and the protrusions 2, with the protrusions 2 arranged in a ring array around the central axis of the ring body 1, in dynamic sealing applications, the protrusions 2 can increase the friction between the sealing ring and the mating surface, prevent the sealing ring from shifting, and improve its stability.

[0019] Please see Figures 1-3A compression-type rubber sealing ring has a compression groove 3 inside the ring body 1, a ring head 4 installed on the top of the ring body 1, and a deformation groove 5 on the inner side wall of the ring head 4. The compression groove 3 is set at the center of the ring body 1 and is diamond-shaped. The ring head 4 is bonded to the ring body 1 and is cone-shaped at the top. Through the compression groove 3, the ring head 4, and the deformation groove 5, the compression groove 3 is diamond-shaped. When the ring body 1 is compressed, the two sides of the compression groove 3 will deform outward, so that the inner and outer sides of the ring body 1 extend outward and closely fit the gap of the sealing coupling surface. This avoids uneven stress on the ring body 1 and deformation to one side. At the same time, the deformation groove 5 can reduce local stress concentration on the sealing surface, prevent the ring head 4 from cracking due to excessive compression, and ensure uniform contact pressure distribution, thus improving sealing reliability.

[0020] Working principle: In use, firstly, the ring body 1 is fitted onto the connection point of the mechanical parts. The protrusions 2 are arranged in a ring array around the central axis of the ring body 1. In dynamic sealing scenarios, the protrusions 2 increase the friction between the sealing ring and the mating surface, preventing the sealing ring from shifting and improving its stability. Then, the sealing sleeve is tightened, and pressure is applied to the ring head 4. The extrusion groove 3 is diamond-shaped. When the ring body 1 is compressed, the two sides of the extrusion groove 3 deform outward, causing the inner and outer sides of the ring body 1 to extend outward and fit tightly against the gap of the sealing mating surface. This prevents uneven stress on the ring body 1 and deformation to one side. At the same time, the deformation groove 5 reduces local stress concentration on the sealing surface, preventing the ring head 4 from cracking due to excessive compression. It also ensures uniform contact pressure distribution and improves sealing reliability. This completes the use of the device.
