Description

Technical Field

[0001] This utility model relates to the field of rubber parts technology, specifically a high-sealing, precise rebound rubber gasket. Background Technology

[0002] Rubber gaskets are widely used in industrial production and equipment operation to ensure the sealing performance of pipe connections, pressure vessels, and hydraulic systems.

[0003] In practical applications, existing rubber gaskets typically use one-piece rubber gaskets. However, due to the limitations of a single material, one-piece rubber gaskets are prone to elastic fatigue under long-term pressure, temperature changes, and media corrosion. Furthermore, their strength is insufficient, their service life often falls short of requirements, and they require frequent maintenance. The resilience of ordinary gaskets relies entirely on the elasticity of the rubber itself; with increased use, the rebound accuracy deviates significantly, making it difficult to maintain a stable sealing pressure. In high-frequency pressure fluctuation environments, sealing failure is highly likely, posing a serious threat to production safety. To address the shortcomings of existing technologies, this invention provides a high-precision, high-sealing, rebound rubber gasket to solve the aforementioned problems. Utility Model Content

An elastic component is embedded between gasket A and gasket B, ensuring high rebound precision and long service life. This guarantees the stability of the sealing pressure during long-term use, reducing maintenance frequency. The inner reinforcing ring forms a rigid support frame, further enhancing gasket stability. The gasket remains stable even under high-frequency vibration, meeting usage requirements.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-sealing precision rebound rubber gasket, comprising a gasket A part and a gasket B part, wherein an inner reinforcing ring is fixedly connected to the inner ring portion of the gasket A part;

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0025] This utility model discloses a high-sealing, precision-rebound rubber gasket, according to the attached... Figure 1 To be continued Figure 3 As shown, it includes a gasket A part 1 and a gasket B part 2. An inner reinforcing ring 3 is fixedly connected to the inner ring of the gasket A part 1. An embedding groove 4 is formed between the gasket B part 2 and the inner reinforcing ring 3 for engaging the gasket B part 2. The gasket B part 2 is provided with a snap-fit ​​part 21 and the snap-fit ​​part 21 engages with the embedding groove 4. An elastic member 5 is movably snapped between the gasket A part 1 and the gasket B part 2 and the elastic member 5 is in a compressed state.

[0026] According to the appendix Figure 1 and attached Figure 2 As shown, the snap-fit ​​part 21 has an inner limiting groove 22 on its side, and the inner reinforcing ring 3 has a limiting ring 31, which is slidably connected in the inner limiting groove 22. This design allows the gasket B part 2, gasket A part 1, and inner reinforcing ring 3 to form an interlocking limit after assembly. During the use of the gasket, even if it is subjected to external force, the components are not easy to separate, thus ensuring the stability of the entire gasket structure and facilitating installation or carrying.

[0027] According to the appendix Figure 3 As shown, furthermore, a first elastic element retainer 23 for locking and limiting the elastic member 5 is fixedly connected inside the gasket B part 2. The first elastic element retainer 23 can accurately fix the position of one end of the elastic member 5, prevent the elastic member 5 from shifting during use, and ensure that the elastic member 5 is always in the correct position to exert its elastic function.

[0028] According to the appendix Figure 2 As shown, furthermore, a second elastic element holder 41 for locking and limiting the elastic element 5 is fixedly connected inside the embedding groove 4. The second elastic element holder 41 cooperates with the first elastic element holder 23 to lock and limit the two ends of the elastic element 5, further enhancing the stability of the elastic element 5 in the gasket, so that the elastic element 5 can provide rebound force more reliably.

[0029] According to the appendix Figure 1 To be continued Figure 3 As shown, the inner reinforcing ring 3 can be made of metal. The inner reinforcing ring 3 made of metal has high strength and hardness, which can provide good support and reinforcement for the gasket, making the gasket less prone to deformation when subjected to large pressure, thus ensuring the sealing performance and service life of the gasket.

[0030] According to the appendix Figure 1 To be continued Figure 3 As shown, the inner reinforcing ring 3 can also be made of engineering plastic. The inner reinforcing ring 3 made of engineering plastic has a certain strength and toughness, and is relatively lightweight, which can meet the requirements of some applications with weight requirements. In addition, engineering plastic also has good corrosion resistance and can adapt to different usage environments.

[0031] According to the appendix Figure 1 To be continued Figure 3 As shown, the elastic component 5 is a helical spring. The helical spring has good elasticity and recovery ability. It can undergo elastic deformation when subjected to pressure and quickly return to its original shape when the pressure is removed, providing precise rebound force for the gasket and ensuring the sealing performance of the gasket.

[0032] According to the appendix Figure 1 To be continued Figure 3 As shown, the elastic component 5 can also be an elastic rubber column. The elastic rubber column also has a certain degree of elasticity and can deform and recover to a certain extent. Moreover, the rubber material also has a certain degree of sealing, which can enhance the sealing effect of the gasket while providing rebound force.

[0033] According to the appendix Figure 1 To be continued Figure 3 As shown, it is particularly important to emphasize that gasket A1 and gasket B2 are made of oil-resistant and high-temperature-resistant synthetic rubber. Gaskets made of this material can maintain good performance in high-temperature and oily environments, and are not prone to aging or deformation, thus ensuring the sealing performance and service life of the gasket, making them suitable for various complex working environments.

[0034] The working principle of this high-sealing precision rebound rubber gasket is as follows: When the gasket is under pressure, the snap-fit ​​portion 21 of gasket B 2 is squeezed within the embedded groove 4, while the elastic component 5 is compressed. The inner limiting groove 22 and the limiting ring 31 cooperate to prevent the components from disengaging. The elastic force of the elastic component 5 allows gasket A 1 and gasket B 2 to be tightly snapped into the sealing position, achieving high sealing performance. When the gasket is disassembled and the pressure disappears, the elastic component 5, being in a compressed state, generates a restoring elastic force, pushing gasket B 2 and gasket A 1 away from each other, allowing the gasket to return to its initial state, thus achieving precise rebound. This ensures continued sealing performance during subsequent use.

[0035] The steps for using this high-sealing precision rebound rubber gasket are as follows: First, place the elastic component 5 on the first elastic element holder 23 of the gasket B part 2. Then, assemble the gasket A part 1 and the gasket B part 2 so that the snap-fit ​​part 21 of the gasket B part 2 snaps into the embedded groove 4. At the same time, the other end of the elastic component 5 snaps into the second elastic element holder 41, and the limiting ring 31 on the inner reinforcing ring 3 slides into the inner limiting groove 22 on the side of the snap-fit ​​part 21. After the assembly is completed, the gasket can be installed on the part that needs to be sealed.

[0036] The advantages of this high-sealing precision rebound rubber gasket are as follows: the design of the inner reinforcing ring 3, the embedded groove 4, and the snap-fit ​​part 21 achieves a stable connection between the various components of the gasket; the interlocking limiting design of the inner limiting groove 22 and the limiting ring 31 further enhances the structural stability of the gasket, making it easy to install and carry; various materials of the inner reinforcing ring 3 and the elastic part 5 are available to meet different usage environments and needs; the use of oil-resistant and high-temperature resistant synthetic rubber material enables the gasket to maintain good sealing performance and service life in complex environments.
