Description

Technical Field

[0001] This utility model relates to the field of rubber sealing ring technology, and in particular to a tensile-resistant rubber sealing ring. Background Technology

[0002] Rubber seals are key sealing components in hydraulic systems, automotive transmissions, pipeline connections, and electronic equipment. However, in actual use, seals often experience tensile deformation and cracking due to assembly tension, medium pressure, or long-term stress, leading to seal failure, increased equipment maintenance costs, and safety hazards. Generally, rubber seals improve their tensile strength by adding reinforcing materials to their surface. However, the presence of external reinforcing materials affects the appearance and flatness of the seal, making it difficult to meet the stringent requirements of precision equipment for seal appearance and affecting the practicality of rubber seals. Utility Model Content

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a tensile-resistant rubber sealing ring, thereby improving the tensile resistance of the rubber sealing ring and reducing the impact of tensile measures on the appearance of the sealing ring.

[0004] This utility model also provides a rubber sealing ring with the aforementioned tensile strength, comprising: an annular sleeve, an inner ring disposed inside the annular sleeve, an adhesive disposed on the inner wall of the annular sleeve, the side surface of the inner ring contacting the adhesive, a groove disposed on the surface of the inner ring, multiple protrusions fixedly connected to the upper and lower inner walls of the groove, and a tensile coating disposed on the interior of the groove and the surface of the inner ring. This improves the tensile strength of the sealing ring and reduces the impact of tensile strength measures on the appearance of the sealing ring.

[0005] According to the present invention, a tensile-resistant rubber sealing ring has notches on both the upper and lower surfaces of the inner ring, and one end of the annular sleeve contacts the surface of the notch. This improves the flatness of the joint.

[0006] According to the present invention, a tensile-resistant rubber sealing ring is provided, wherein the annular sleeve, the inner ring, and the protrusion are all made of fluororubber, and the adhesive is a special fluororubber adhesive. The annular sleeve and the inner ring are integrated.

[0007] According to the present invention, a tensile rubber sealing ring is provided, wherein the protrusion does not contact the inner wall of the groove, and the tensile coating is a polyurethane composite coating made of elastic polyurethane resin and short fibers. This improves the smoothness of the groove filling.

[0008] Beneficial effects: The tensile rubber sealing ring of this technical solution forms a double-layer rubber sealing ring through an annular sleeve and an inner ring. The grooves and tensile coating on the surface of the inner ring increase the tensile strength of the sealing ring. At the same time, the structure of the tensile material is embedded in the ring, which reduces the damage to the tensile material and avoids affecting the flatness of the sealing ring. The protrusions inside the groove increase the adhesion points of the coating and improve the stability of the tensile coating. Attached Figure Description

[0011] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0012] Reference Figure 1-4 This utility model provides a tensile-resistant rubber sealing ring, which includes: an annular sleeve 1, an inner ring 2 inside the annular sleeve 1, and notches 7 on both the upper and lower surfaces of the inner ring 2. One end of the annular sleeve 1 contacts the surface of the notch 7. The notch 7 is used to increase the flatness after the inner ring 2 and the annular sleeve 1 are joined. An adhesive 6 is provided on the inner wall of the annular sleeve 1. The side surface of the inner ring 2 contacts the adhesive 6. The adhesive 6 is used to integrate the inner ring 2 and the annular sleeve 1.

[0013] Specifically, when splicing the sealing ring, first apply adhesive 6 to the inner wall of the annular sleeve 1, then manually press the inner ring 2 into the annular sleeve 1, and apply additional pressure to the part of the annular sleeve 1 corresponding to the notch 7, so that the edge of the annular sleeve 1 fits tightly against the notch 7, thereby improving the flatness of the inner wall of the sealing ring.

[0014] The surface of the inner ring 2 is provided with a groove 3. Multiple protrusions 5 are fixedly connected to the upper and lower inner walls of the groove 3. The protrusions 5 do not contact the inner wall of the groove 3. The annular sleeve 1, the inner ring 2, and the protrusions 5 are all made of fluororubber. The adhesive 6 is a special adhesive material for fluororubber. The inside of the groove 3 and the surface of the inner ring 2 are provided with a tensile coating 4. The tensile coating 4 is a polyurethane composite coating made of elastic polyurethane resin and short fibers. The tensile coating 4 is used to increase the tensile strength of the rubber sealing ring. The groove 3 and the protrusions 5 cooperate to increase the stress points of the tensile coating 4 and increase the integration effect of the tensile coating 4 and the inner ring 2.

[0015] Specifically, before splicing the inner ring 2 of the ring sleeve 1, the inner ring 2 is taken out separately and an anti-tensile coating 4 is applied to the surface of the inner ring 2. Since the liquid polyurethane composite coating has high fluidity, the anti-tensile coating 4 that enters the groove 3 flows and fills the gap between the protrusion 5 and the inner wall of the groove 3. At this time, the stress points of the cooled anti-tensile coating 4 increase, making it more difficult for the anti-tensile coating 4 to detach.

[0016] Working principle: When assembling the sealing ring, a layer of tensile coating 4 is applied to the surface of the inner ring 2. Since the liquid polyurethane composite coating has high fluidity, the tensile coating 4 that enters the groove 3 completely fills the groove 3. After the tensile coating 4 is added, adhesive 6 is first applied to the inside of the annular sleeve 1, and then the inner ring 2 is manually pressed into the annular sleeve 1. Due to the presence of the notch 7, there is no protrusion at the joint between the two, keeping it in a smooth state. At the same time, adhesive 6 can be applied to the joint between the inner ring 2 and the annular sleeve 1, and the joint can be heated to increase the integration effect of the inner ring 2 and the annular sleeve 1, while eliminating the splicing marks and further increasing the integrity of the sealing ring surface.

[0017] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model 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 utility model.
