Description

Technical Field

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

[0002] Spring-loaded seals, also known as spring-storage seals, are sealing devices that provide continuous sealing pressure through an internal spring. They are widely used in various working conditions, performing particularly well in dynamic sealing environments. They offer advantages such as high reliability, automatic compensation capability, wide temperature range, and applicability to a wide range of media. The Pan-Plug seal is one of the most common types of spring-loaded seals.

[0003] However, existing elastic seals also have some drawbacks: on the one hand, the elastic element is simply wrapped with rubber, such as the Pan-Seal ring. It is obvious that the wrapping area is small, the installation is not stable enough, and the elastic element may fall off. On the other hand, existing elastic seals can generally only perform axial sealing or only radial sealing. Their functions are limited and their applicability needs to be improved. Mistake-proofing is required in production and sales to avoid mixing materials and increase the difficulty. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, this utility model provides an elastic rubber sealing ring in which a continuous, smooth, arc-shaped, "bow"-shaped, annular spring sheet is inserted into the conformal groove and open groove of the rubber ring. The spring sheet can be compressed or stretched in both the axial and radial directions, thus enabling the rubber ring to provide both axial and radial sealing, making it widely applicable. Furthermore, the conformal groove covers a large area of ​​the spring sheet, ensuring stable installation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an elastic rubber sealing ring comprising an annular rubber ring and an annular spring sheet. The cross-section of the spring sheet is a "bow" shape with a continuous smooth arc. The central convex side of the spring sheet faces inward. An open groove is formed at the center of the inner ring of the rubber ring, and the bottom of the open groove corresponds to the central recess of the spring sheet. A contoured groove corresponding to the upper and lower parts of the spring sheet is formed inside the rubber ring. The contoured groove communicates with the open groove, and the spring sheet is installed in the contoured groove and the open groove.

[0006] Preferably, the inner ring of the rubber ring has a plurality of locking posts evenly arranged at the center position of the bottom of the opening groove, and the spring sheet has a plurality of locking holes evenly opened at the center position, and the locking posts can be inserted into the locking holes accordingly.

[0007] Preferably, the cross-section of the rubber ring is rectangular.

[0008] Preferably, the inner and outer rings of the rubber ring are respectively provided with an inner radial retaining ring and an outer radial retaining ring with a semi-circular cross section at the positions where the spring sheet is radially protruding or recessed.

[0009] Preferably, the upper and lower end faces of the rubber ring are respectively provided with axial retaining rings with semi-circular cross sections at the positions corresponding to the axial protrusions of the spring sheet.

[0010] This utility model provides an elastic rubber sealing ring, which has the following beneficial effects:

[0011] 1. This utility model inserts a continuous, smooth, arc-shaped, "bow"-shaped, annular spring sheet into the contour groove and open groove of the rubber ring. The spring sheet can be compressed or stretched in both the axial and radial directions, so that the rubber ring can perform both axial and radial sealing, making it widely applicable. Moreover, the contour groove covers a large area of ​​the spring sheet, ensuring stable installation.

[0012] 2. In this utility model, multiple locking posts are evenly arranged at the bottom center position of the inner ring of the rubber ring corresponding to the opening groove, and multiple locking holes are evenly arranged at the center position of the spring sheet. After the spring sheet is installed in the rubber ring, the locking posts can be inserted into the locking holes accordingly, further ensuring the stability of the spring sheet and the rubber ring.

[0013] 3. In this utility model, the upper and lower end faces of the rubber ring are respectively provided with axial retaining rings with semi-circular cross sections. The retaining rings are set at the positions where the spring sheet is axially protruding. When the spring sheet is compressed, the protruding position deforms the most and the elastic force is concentrated. The design of the axial retaining ring is used to compensate for the deformation at this point and improve the sealing performance. Similarly, inner radial retaining rings and outer radial retaining rings can also be provided at the positions where the inner and outer rings of the rubber ring are radially protruding or recessed corresponding to the spring sheet.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-2 As shown, an elastic rubber sealing ring includes an annular rubber ring 1 and an annular spring sheet 5. The cross-section of the spring sheet 5 is a "bow" shape with a continuous smooth arc. The central convex side of the spring sheet 5 faces inward. An open groove 2 is formed at the center of the inner ring of the rubber ring 1. The bottom of the open groove 2 corresponds to the central recess of the spring sheet 5. A contoured groove 3 corresponding to the upper and lower parts of the spring sheet 5 is formed inside the rubber ring 1. The contoured groove 3 communicates with the open groove 2. The spring sheet 5 is installed in the contoured groove 3 and the open groove 2. The inner ring of the rubber ring 1 has multiple locking posts 4 evenly arranged at the center of the bottom of the opening groove 2, and the center of the spring sheet 5 has multiple locking holes 6 evenly arranged, and the locking posts 4 can be inserted into the locking holes 6 respectively; the cross-section of the rubber ring 1 is rectangular; the inner and outer rings of the rubber ring 1 are respectively provided with inner radial retaining rings 8 and outer radial retaining rings 9 with semi-circular cross-sections at the radial protrusions or depressions of the spring sheet 5; the upper and lower end faces of the rubber ring 1 are respectively provided with axial retaining rings 7 with semi-circular cross-sections at the axial protrusions of the spring sheet 5.

[0019] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows:

[0020] According to the instruction manual Figure 1-2As can be seen, in this utility model, the annular rubber ring 1 and the annular spring sheet 5, with the spring sheet 5 having a "bow"-shaped cross-section, can be installed into the contour groove 3 and the open groove 2 of the rubber ring 1. Because the cross-section of the spring sheet 5 is a continuously smooth "bow" shape, it can be compressed or stretched in both the axial and radial directions. In use, if axial sealing is applied, after installation or during operation, the rubber ring 1 and the spring sheet 5 are subjected to axial compression. The reaction force allows the upper and lower ends of the rubber ring 1 to press against the sealing component, ensuring a seal. Similarly, if radial sealing is applied, after installation or during operation, the rubber ring 1 and the spring sheet 5 are subjected to radial compression. The reaction force allows the inner and outer rings of the rubber ring 1 to press against the sealing component, ensuring a seal. This utility model can perform both axial and radial sealing, increasing functionality and improving applicability and practicality. In addition, the large area of ​​the contoured groove 3 covering the spring sheet 5, combined with the fit of the opening groove 2 to the central recessed side of the spring sheet 5, ensures stable installation of the spring sheet 5. It is not easy to fall off during installation and operation, thus improving the reliability of the seal and the service life during use.

[0021] Among them, multiple locking posts 4 are evenly arranged at the center position of the bottom of the opening groove 2 corresponding to the inner ring of the rubber ring 1, and multiple locking holes 6 are evenly opened at the center position of the spring sheet 5. The locking posts 4 can be inserted into the locking holes 6 to further ensure the stability of the spring sheet 5 and the rubber ring 1.

[0022] Among them, the cross-section of the rubber ring 1 is rectangular. The rectangular rubber ring 1 is relatively easy to produce and process, and it is also relatively easy to install the spring plate 5.

[0023] In this design, the inner and outer rings of the rubber ring 1 are respectively equipped with an inner radial retaining ring 8 and an outer radial retaining ring 9 with a semi-circular cross-section at the radial protrusions or recesses of the spring sheet 5. When the spring sheet 5 is compressed, the deformation is greatest at the protrusions, and the elastic force is more concentrated. The axial retaining ring 7 is designed to compensate for this deformation and improve the sealing performance. Similarly, the upper and lower end faces of the rubber ring 1 are respectively equipped with axial retaining rings 7 with a semi-circular cross-section at the axial protrusions of the spring sheet 5 to improve the sealing performance. The semi-circular cross-section design is quite common and has a wide range of applications.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
