Description

Technical Field

[0001] This utility model relates to the field of silicone sealing rings, and in particular to a silicone sealing ring. Background Technology

[0002] In modern industry and daily life, sealing technology is one of the key factors in ensuring the stable and safe performance of equipment and products. Silicone sealing rings, as a highly elastic and durable sealing material, are widely used in various environmental conditions due to their unique physical and chemical properties. Their main component is siloxane, which, when mixed with catalysts and other additives, forms a silicone preform with certain fluidity and curing properties. Silicone sealing rings exhibit excellent high and low temperature resistance, maintaining their physical properties within a temperature range of -60℃ to 250℃. Furthermore, they possess good chemical corrosion resistance, electrical insulation, flexibility, compressibility, and are non-toxic and odorless, making them widely used in the food and medical industries.

[0003] However, most existing sealing rings typically have square or circular cross-sections. In actual use, once the sealing ring softens or breaks due to prolonged heat or stress, its sealing performance will significantly decrease, failing to meet the ideal airtightness requirements. This not only greatly reduces the sealing effect but may also cause problems such as water and air leakage, causing inconvenience to users. Users often need to frequently replace the sealing rings to ensure the normal use of the equipment and the reliability of the sealing performance. Summary of the Invention

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0005] A silicone sealing ring includes a silicone ring body, the silicone ring body having an inner ring and an outer ring, the inner ring having at least two inwardly protruding first convex rings evenly arranged in the longitudinal direction, the outer ring having at least two outwardly protruding second convex rings evenly arranged in the longitudinal direction, the inner ring and the outer ring being integrally connected, the first convex rings being integrally connected to the inner ring, the second convex rings being integrally connected to the outer ring, the outer ring having a reinforcing layer on its surface, the second convex rings having a reinforcing layer on their surface, the outer ring having an inner hole, the inner ring being fitted into the inner hole, and the inner ring having flanges at both ends, the flanges being fitted into the two ends of the inner hole.

[0006] As a further embodiment of this utility model: the distance between adjacent first convex rings is 0.3-0.5mm, and the distance between adjacent second convex rings is 0.3-0.5mm.

[0007] As a further embodiment of this utility model: the cross-section of the first convex ring is circular, and the cross-section of the second convex ring is also circular.

[0008] As a further embodiment of this utility model: the thickness of the silicone sealing ring gradually decreases from the middle to both ends, and the port of the inner ring is rounded.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1.

[0029] Please see Figures 1-3 In the first embodiment of this utility model, a silicone sealing ring includes a silicone ring body 1. The silicone ring body 1 has an inner ring 12 and an outer ring 13. The inner ring 12 has at least two inwardly protruding first convex rings 14, which are evenly arranged in the longitudinal direction. The outer ring 13 has at least two outwardly protruding second convex rings 15, which are evenly arranged in the longitudinal direction. Specifically, in a cross-sectional view, the sealing ring has the following cross-sectional shape: one side of the inner ring 12 extends to the port in a wavy shape, and the other side of the outer ring 13 extends to the port in a wavy shape. The first convex rings 14 are evenly stacked on the inner surface of the inner ring 12 to form a multi-layered protruding structure in the inner ring 12, which can enhance the sealing performance of the inner ring 12. The second convex rings 15 are evenly stacked on the outer surface of the outer ring 13 to form a multi-layered protruding structure in the outer ring 13, which can enhance the sealing performance of the outer ring 13. The working principle of this embodiment is as follows: By providing a first convex ring 14 and a second convex ring 15 on the inner ring 12 and the outer ring 13 of the sealing ring respectively, the inner ring 12 and the outer ring 13 of the sealing ring have multiple sealing areas. This sealing ring can be used in environments with strict airtightness requirements, and the multiple sealing areas can significantly improve the sealing performance of the sealing ring.

[0030] Further as Figures 1-3 As shown, in this embodiment of the invention, the inner ring 12 and the outer ring 13 are integrally connected, the first convex ring 14 is integrally connected to the inner ring 12, and the second convex ring 15 is integrally connected to the outer ring 13. The sealing ring can be formed by injection molding.

[0031] In embodiments of this invention, a reinforcing layer is provided on the surface of the outer ring 13, and a reinforcing layer is provided on the surface of the second convex ring 15. The reinforcing layer can be made of soft aluminum, hydrogenated nitrile rubber, or polyphenylene sulfide. The hydrogenated nitrile rubber layer has excellent corrosion resistance, tear resistance, and compression set resistance.

[0032] Further as Figures 4-6As shown, in another embodiment of this utility model, the outer ring 13 has an inner hole 131, and the inner ring 12 is fitted into the inner hole 131. Specifically, the first convex ring 14 is integrally connected to the inner ring 12, and the second convex ring 15 is integrally connected to the outer ring 13. The inner ring 12 and the outer ring 13 can be formed by injection molding. The working principle of this embodiment is as follows: the inner ring 12 with a corrugated inner wall is detachably installed in the inner hole 131 of the outer ring 13, and the outer surface of the outer ring 13 is also corrugated. The double-layer sealing structure can ensure the sealing performance. The inner ring 12 and the outer ring 13 are replaceable, which is convenient for people to replace in time to ensure the sealing performance.

[0033] Further as Figures 1-4 As shown, in another embodiment of this utility model, the inner ring is provided with flanges 121 at both ends, and the flanges 121 are engaged at both ends of the inner hole. The inner ring 12 is provided with flanges 121 for engaging and sealing at its ends. The outer ring 13 is provided with connecting holes. The inner ring 12 is inserted into the connecting holes, and the flanges 121 are engaged in the connecting holes of the outer ring 13, thereby completing the installation of the inner ring 12.

[0034] Further as Figures 1-2 As shown, in another embodiment of this utility model, the distance between adjacent first convex rings is 0.3-0.5mm, and the distance between adjacent second convex rings is 0.3-0.5mm.

[0035] Further as Figures 2-3 As shown, in another embodiment of this utility model, the first convex ring has a circular cross-section, and the second convex ring has a circular cross-section.

[0036] Further as Figures 7-9 As shown in the embodiment of this utility model, the thickness of the silicone sealing ring gradually decreases from the middle to both ends, and the ends of the inner ring 12 are rounded. The length of both ends of the inner ring 12 in the longitudinal direction is not less than the length of both ends of the outer ring 13 in the longitudinal direction, and the ends of the inner ring 12 are rounded. The end thickness of the sealing ring allows it to fit the surface better during installation. For example, when the sealing ring is used to install on a cylindrical product, its ends can better fit the surface of the cylindrical product. The rounding at the ends of the inner ring 12 facilitates demolding.

[0037] like Figure 9 As shown in another embodiment of this utility model, the first protruding ring 14 is spaced apart from the port of the sealing ring. Since the sealing ring is made of silicone and has a certain degree of elasticity, the port of the sealing ring will shrink inward when installed on the product. The reserved gap allows the sealing ring to be unrestricted by the first protruding ring 14 when installed on the product, enabling the port of the sealing ring to shrink and fit against the surface of the product to be sealed. Therefore, when the first protruding ring 14 is provided in the inner ring 12, a certain gap needs to be reserved at both ends of the sealing ring to ensure that the port of the sealing ring is not restricted by the first protruding ring 14 when it shrinks inward.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
