[0001] This utility model belongs to the field of rubber ring technology, and in particular relates to a composite rubber ring. Background Technology
[0002] Rubber rings are primarily used for sealing and vibration damping, and are widely used in various mechanical equipment and industrial fields. In mechanical equipment, rubber rings act as seals to prevent the leakage of liquids and gases, ensuring the stable operation of equipment and systems. They are suitable for high-pressure, vacuum, and humid environments, maintaining stability under these conditions.
[0003] Due to the inherent material properties of rubber rings, they can deform and become damaged when subjected to prolonged and intense pressure, severely affecting their sealing performance. As a result, existing rubber rings have a short service life and poor practicality. Utility Model Content

[0026] To better understand the purpose, structure, and function of this utility model, a composite rubber ring of this utility model will be described in further detail below with reference to the accompanying drawings.
[0027] like Figure 1-4 As shown, this utility model discloses a composite rubber ring, comprising a lower ring body 1 and an upper ring body 2. The lower ring body 1 and the upper ring body 2 are connected by multiple elastic telescopic structures arranged in a circumferential array. The lower ring body 1 includes a rubber ring 3, an inner steel plate 4, and an outer steel plate 5. The inner wall of the rubber ring 3 is fixedly connected to the outer wall of the inner steel plate 4, and the outer wall of the rubber ring 3 is fixedly connected to the inner wall of the outer steel plate 5. A sealing surface 6 is provided at the bottom of the rubber ring 3. The surface of the sealing surface 6 contacts the end faces of the inner steel plate 4 and the outer steel plate 5. The surface of the sealing surface 6 is provided with three annular protrusions 11, the diameter of which decreases sequentially. By setting three protrusions 11 of different diameters, three sealing contact surfaces can be formed when the rubber ring contacts the workpiece, thereby greatly improving the sealing effect. The structure of the upper ring body 2 is the same as that of the lower ring body 1. The outer side wall of the inner steel plate 4 and the inner side wall of the outer steel plate 5 are provided with multiple trapezoidal grooves 13 arranged in a circumferential array. The inner and outer side walls of the rubber ring 3 are provided with multiple trapezoidal blocks 14 that correspond one-to-one with the trapezoidal grooves 13. The size of the trapezoidal blocks 14 matches the size of the trapezoidal grooves 13. Through the cooperation between the trapezoidal blocks 14 and the trapezoidal grooves 13, the rubber ring 3 is limited to the inner steel plate 4 and the outer steel plate 5. This can effectively prevent the rubber ring 3 from sliding between the inner steel plate 4 and the outer steel plate 5, ensuring the stability of the structure. Furthermore, the setting of the inner steel plate 4 and the outer steel plate 5 greatly enhances the strength of the rubber ring, effectively preventing the deformation of the rubber ring caused by strong compression. This has a significant protective effect and greatly extends the service life of the rubber ring.
[0028] The elastic telescopic structure includes a sliding column 8, the top of which is fixedly connected to the bottom of the rubber ring 3 of the upper ring body 2. The upper surface of the rubber ring 3 of the lower ring body 1 is provided with sliding holes 7 corresponding to the sliding column 8. The diameter of the sliding column 8 matches the diameter of the sliding hole 7, and the sliding column 8 and the sliding hole 7 are slidably connected up and down. A spring 9 is provided between the bottom of the sliding column 8 and the bottom inner wall of the sliding hole 7. Through the arrangement of the sliding column 8, the spring 9 and the sliding hole 7, the upper ring body 2 and the lower ring body 1 have an elastic telescopic function, which makes it easier and more convenient to install the rubber ring. Under the action of the spring 9, the upper and lower sealing surfaces 6 can be tightly connected with the contact surface of the workpiece, which greatly improves the sealing effect. Limiting blocks 10 are provided on both sides of the bottom of the sliding column 8, and limiting grooves 12 corresponding to the limiting blocks 10 are provided on both sides of the inner wall of the sliding hole 7. The limiting blocks 10 and the limiting grooves 12 are slidably connected up and down, and the limiting grooves 12 have a closed top structure. Through the cooperation between the limiting blocks 10 and the limiting grooves 12, the sliding column 8 is limited. At the same time, it can effectively prevent the sliding column 8 from detaching from the sliding hole 7.
