[0002] Rubber rings are fundamental components used in mechanical design, primarily for static or dynamic sealing to prevent liquid or gas leaks. Antioxidant rubber rings are made from materials with excellent oxidation resistance.

[0003] Traditional rubber rings have poor oxidation resistance and a short service life during use. Especially under high temperature conditions, the rubber rings may deform, thus affecting their sealing performance. Utility Model Content

[0004] In order to overcome the shortcomings of traditional rubber rings, such as poor oxidation resistance and easy deformation at high temperatures, which affects the sealing performance and shortens the service life, this utility model can provide an oxidation-resistant rubber ring.

[0005] The technical solution of this utility model is as follows: an oxidation-resistant rubber ring, comprising an upper rubber pad, a lower rubber pad, an outer rubber ring, an inner rubber ring, and a conical ring. The lower rubber pad has an outer rubber ring and a conical ring at its top. The conical ring is located inside the outer rubber ring, and a groove is formed between the conical ring and the outer rubber ring. The inner rubber ring is fitted inside the groove and fits into the groove. The upper rubber pad is located at the top of the inner rubber ring. The upper rubber pad includes a rubber layer, a high-temperature resistant layer is attached to the outside of the rubber layer, an anti-corrosion layer is attached to the outside of the high-temperature resistant layer, an anti-oxidation layer is attached to the outside of the anti-oxidation layer, and a wear-resistant layer is attached to the outside of the anti-oxidation layer. Both the lower rubber pad and the upper rubber pad adopt the same composite structure design.

[0006] In one embodiment, the wear-resistant layer is made of polyurethane.

[0007] In one embodiment, the antioxidant layer is coated with an ultraviolet light absorber.

[0008] In one embodiment, the anti-corrosion layer is coated with an epoxy resin coating.

[0009] In one embodiment, the high-temperature resistant layer is coated with lead phosphate powder coating.

[0010] In one embodiment, the tapered ring has a structure in which the width gradually decreases from top to bottom, and the inner rubber ring is designed with a bottom opening narrower than the inner top side.

[0011] The beneficial effects of this utility model are as follows: 1. The design of coating the antioxidant layer with ultraviolet light absorber slows down the aging rate of the rubber and extends its service life. The design of coating the high temperature resistant layer with phosphate lead powder coating enables the rubber ring to work stably in high temperature environment.

[0012] 2. The conical ring design of this utility model enables the upper and lower rubber pads to be stably connected through the tight fit between the inner rubber ring and the conical ring. Attached Figure Description

[0018] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0019] An antioxidant rubber ring, such as Figures 1-4As shown, it includes an upper rubber pad 1, a lower rubber pad 2, an outer rubber ring 3, an inner rubber ring 4, and a conical ring 5. The lower rubber pad 2 has an outer rubber ring 3 and a conical ring 5 on its top. The conical ring 5 has a structure where the width gradually decreases from top to bottom. The conical ring 5 is located inside the outer rubber ring 3, and a groove is formed between the conical ring 5 and the outer rubber ring 3. The inner rubber ring 4 is fitted inside the groove. The inner rubber ring 4 is designed with a bottom opening narrower than the top inner side. The inner rubber ring 4 fits into the groove. The upper rubber pad 1 is located on the top of the inner rubber ring 4. The upper rubber pad 1 includes a rubber layer 15. A high-temperature resistant layer 14 is attached to the outside of the rubber layer 15. The high-temperature resistant layer 14 is coated with a layer of lead phosphate powder coating. This inorganic high-temperature resistant coating is not only low in cost and simple to prepare, but also gives the rubber ring heat resistance, corrosion resistance, and electrical conductivity, making the rubber ring more durable and durable. The rubber ring can work stably in high-temperature environments. The high-temperature resistant layer 14 is covered with an anti-corrosion layer 13, which is covered with an epoxy resin coating, providing corrosion protection and chemical resistance to the rubber surface and effectively preventing corrosive substances from penetrating into the rubber layer 15. The anti-oxidation layer 12 is covered with an anti-oxidation layer 12, which is coated with a UV absorber, effectively blocking ultraviolet rays and ozone from contacting the rubber layer 15 and slowing down the aging rate of the rubber ring. The anti-oxidation layer 12 is covered with a wear-resistant layer 11, which is made of polyurethane material with extremely high wear resistance. It can maintain excellent elasticity and recovery ability even under high pressure conditions, effectively resisting external wear and significantly extending the service life of the rubber ring. The lower rubber pad 2 and the upper rubber pad 1 both adopt the same composite structure design.

[0020] Working principle: When this rubber ring needs to be installed, the operator pulls open the opening of the inner rubber ring 4 and then inserts it into the groove formed between the conical ring 5 and the outer rubber ring 3. The inner rubber ring 4 slides along the inclined surface of the conical ring 5. After the opening of the inner rubber ring 4 contacts the bottom of the conical ring 5, the inner rubber ring 4 will be tightly combined with the inner wall of the groove, which improves the sealing performance of this rubber ring. Based on this, the wear-resistant layer 11 uses a polyurethane material with extremely high wear resistance, which can maintain excellent elasticity and recovery ability even under high pressure conditions, effectively resisting external wear and significantly extending the service life of the rubber ring; the high-temperature resistant layer 14 is coated with a layer of lead phosphate powder coating. This inorganic high-temperature resistant coating is not only inexpensive and easy to prepare, but also endows the rubber ring with heat resistance, corrosion resistance and electrical conductivity, enabling the rubber ring to work stably in high-temperature environments; the antioxidant layer 12 is coated with an ultraviolet light absorber, which effectively blocks ultraviolet rays and ozone from contacting the rubber layer 15 and slows down the aging rate of the rubber; the anti-corrosion layer 13 is covered with an epoxy resin coating, which provides corrosion protection and chemical resistance to the rubber surface and effectively prevents corrosive substances from penetrating into the rubber layer 15.

[0021] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
