Description

Technical Field

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

[0002] In industrial production, pipeline transportation, and machinery manufacturing, sealing elements are core components that ensure the normal operation of equipment and prevent media leakage. Among them, rubber sealing rings are widely used in various static or dynamic sealing scenarios due to their good elasticity, wear resistance, and corrosion resistance.

[0003] The elasticity of existing rubber seals mainly depends on the properties of the rubber material itself. However, rubber is prone to plastic deformation under long-term stress, high temperature or aging conditions, which leads to elasticity decay. The lack of effective internal reinforcement makes it prone to phenomena such as "flattening" and "cracking", affecting its service life. Utility Model Content

[0004] I. Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a combined rubber sealing ring that improves the overall elasticity and deformation resistance of the sealing ring and extends the durability of the sealing performance.

[0006] II. Technical Solution

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a combined rubber sealing ring, including a sealing ring body, and further comprising:

[0008] Connecting rings; a pair of connecting rings are respectively fitted onto the top and bottom ends of the sealing ring body, and a locking structure is provided between the connecting rings and the sealing ring body;

[0009] The sealing ring body has a cavity, a triangular metal sheet is disposed in the cavity, and several silicone pads are filled between the cavity and the metal sheet.

[0010] As an improvement, the cross-section of the connecting ring is concave, and the inner wall of the connecting ring is in close contact with the outer wall of the sealing ring body 1.

[0011] As an improvement, the locking structure includes a limiting ring and a limiting groove; two sets of paired limiting rings are respectively disposed on the inner wall of the connecting ring, and two limiting grooves are respectively disposed on the outer wall of the sealing ring body, and the limiting rings are respectively embedded in the limiting grooves.

[0014] III. Beneficial Effects

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] 1. Because the triangular elastic steel sheet has good elastic recovery performance, it can expand and contract synchronously with the deformation of the sealing ring. Combined with the buffering effect of the silicone pad, it enhances the overall elasticity and deformation resistance of the sealing ring, further extending its service life.

[0017] 2. Through the cooperation of the concave connecting ring and the locking structure of the limiting ring and limiting groove, the connecting ring and the sealing ring body form a mechanical engagement, which effectively prevents relative displacement under vibration or pressure, and the connection stability is high.

[0024] In the description of this utility model, it should be understood that the terms "center," "lateral," "upper," "lower," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Additionally, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] To improve overall connection stability, combined with the attached... Figure 1 Appendix Figure 2 and attached Figure 3 A composite rubber sealing ring includes a sealing ring body 1 and a connecting ring 2. Pairs of connecting rings 2 are respectively fitted onto the top and bottom ends of the sealing ring body 1, and a locking structure is provided between the connecting rings 2 and the sealing ring body 1. The locking structure includes limiting rings 3 and limiting grooves 4. Two pairs of limiting rings 3 are respectively disposed on the inner walls of the connecting rings 2, and two limiting grooves 4 are respectively disposed on the outer walls of the sealing ring body 1. The limiting rings 3 are respectively embedded within the limiting grooves 4. The connecting rings 2 have a concave cross-section, and their inner walls are tightly fitted against the outer walls of the sealing ring body 1. Both the sealing ring body 1 and the connecting rings 2 are made of rubber. The concave cross-section of the connecting rings 2, the inner walls tightly fitted against the outer walls of the sealing ring body 1, and the limiting rings 3 embedded within the limiting grooves 4 form a locking structure, greatly improving the overall connection stability.

[0027] To improve the deformation resistance of the sealing ring, combined with the attached... Figure 4 and attached Figure 5 The sealing ring body 1 contains a cavity 5, within which a triangular metal sheet 6 is disposed. Several silicone pads 7 fill the space between the cavity 5 and the metal sheet 6. The metal sheet 6 is made of elastic steel. The triangular elastic steel sheet has excellent elastic recovery properties, allowing it to expand and contract synchronously with the deformation of the sealing ring. Combined with the cushioning effect of the silicone pads 7, this significantly improves the overall resistance to deformation and extends the service life of the sealing ring.

[0028] In specific implementation of this utility model:

[0029] First, align the inner wall limiting ring 3 of the connecting ring 2 with the limiting groove 4 of the sealing ring body 1. Use the rubber elasticity to stretch the connecting ring 2, so that the limiting ring 3 is embedded in the limiting groove 4, thus completing the fixation and forming a locking structure.

[0030] When the sealing ring is subjected to radial or axial pressure, the sealing ring body 1 undergoes elastic deformation. The triangular metal piece 6 in the cavity 5 generates elastic potential energy as it deforms. The force is evenly transmitted to the body through the silicone pad 7, avoiding local stress concentration, improving the overall elasticity and deformation resistance of the sealing ring, and further extending its service life.

This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
