[0002] Seals are critical components in industrial production, machinery, automotive manufacturing, and numerous other fields, and their performance is directly linked to the efficiency, safety, and service life of these equipment. Traditional seals often suffer from issues such as insufficient elasticity, wear, installation difficulties, and poor adaptability. Especially in applications requiring high-frequency vibration, high pressure, high temperature, or corrosive media, traditional seals are prone to leakage due to material aging, wear, or improper installation, leading to equipment failures and even accidents.

[0003] Specifically, traditional seals typically utilize a single material or simple structure, making it difficult to simultaneously meet the requirements of high elasticity and wear resistance. Under high-intensity, high-frequency use, seals are prone to failure due to material fatigue or wear. Furthermore, the installation process for traditional seals is often complex, requiring specialized tools and techniques, and placing strict constraints on the size and shape of the installation environment, significantly limiting the seal's application range and flexibility. To address this, we propose a highly elastic and wear-resistant rubber seal. Utility Model Content

[0031] As a preferred embodiment of the present invention, the inserting plate 13 and the slot 14 are both made of rubber material, and the inserting plate 13 fits tightly against the slot 14. The rubber material has a certain degree of flexibility, which can increase flexibility during use.

[0032] The high elasticity and wear-resistant rubber seal of the utility model is used:

[0033] First of all, the core part of the seal is the sealing gasket body 2 composed of a multi-layer structure, which includes an outer layer 21, a buffer layer 22, a flexible layer 23, a main layer 24 and an inner core 25. Each layer has a specific function and together provides the seal with high elasticity and wear resistance. The outer layer 21, as the outermost layer, is in direct contact with the external environment and has excellent wear resistance and aging resistance. The buffer layer 22 can absorb and disperse external impacts and protect the internal layers from damage. The flexible layer 23 gives the seal good flexibility and deformation ability, enabling it to adapt to various complex installation environments. The main layer 24 is the main load-bearing part of the seal and has high strength and stability. The inner core 25 may provide additional support or sealing functions according to specific needs.

[0034] During installation, the mounting collar 1, located outside the gasket body 2, plays a key role. The collar 1 comprises two symmetrically arranged semi-circular protective rings 10, connected by an adjustment mechanism that allows for easy adjustment of the distance between them to accommodate seals of varying sizes and installation environments. Annular grooves 15 are located at the top and bottom of the protective rings 10, matching the dimensions of the integrally formed connecting rings 20 at the top and bottom of the gasket body 2. This design ensures a stable connection between the gasket body 2 and the collar 1, preventing them from loosening or falling off during use.

[0035] The design of the connecting ring 20 also takes into account the need for easy disassembly and maintenance. It consists of two parts arranged symmetrically and fixedly connected by a fixing screw 12. This design ensures that the connecting ring 20 maintains structural strength while also facilitating disassembly and maintenance, improving the maintenance convenience of the seal.

[0036] Furthermore, one end of the connecting ring 20 is fixedly connected to the plug plate 13, and the other end is provided with a slot 14. During installation, the plug plate 13 on one connecting ring 20 can be plugged into the slot 14 on the other connecting ring 20. This plug-in design not only enhances the connection stability of the connecting ring 20, but also simplifies the installation process and improves installation efficiency.

[0037] The design of the adjustment mechanism allows the mounting sleeve 1 to adapt to a wider range of installation environments. It comprises a center disc 3, a screw 33, an adjustment knob 35, and a mounting head 34. Rotating the adjustment knob 35 drives the screw 33 on the center disc 3, thereby adjusting the distance between the two guard rings 10. This design not only improves the versatility and adaptability of the seal, but also makes the adjustment process more accurate and efficient.

[0038] To further enhance ease and accuracy of adjustment, a drive disk 30 and a drive knob 31 are located on top of the center disk 3. A toothed ring 32 is coaxially fixed to the outer ring of the bottom of the drive disk 30, meshing with teeth on the outer wall of the adjustment knob 35. Rotating the drive disk 30 simultaneously rotates both adjustment knobs 35, achieving synchronized adjustment of the spacing between the two guard rings 10. The drive knob 31 is screw-shaped and has standard dimensions, allowing operators to use standard tools for rotation, further enhancing ease and accuracy of adjustment.

[0039] Two fixed handles 4 are symmetrically provided on the mounting vest 1, which facilitate the operator to hold and fix the mounting vest 1. This not only improves the stability and safety of the installation process, but also enables the operator to perform installation and removal work more conveniently.

[0040] To sum up, the high-elasticity and wear-resistant rubber seal of the utility model achieves multiple advantages such as high elasticity, wear resistance, easy installation and maintenance, and strong adaptability through the design of a multi-layer structure, an adjustment mechanism for installing the vest 1, a plug-in design of the connecting ring 20, and the coordination of various preferred schemes, providing a high-quality solution for various sealing needs.
