Description

Technical Field

[0001] This utility model relates to the field of rubber sealing ring technology, specifically a highly elastic rubber sealing ring. Background Technology

[0002] Rubber sealing rings are ring-shaped parts made of rubber material. Under static and dynamic conditions, they play the roles of sealing, leak prevention, fixation, and protection. Because of their excellent sealing performance, good aging resistance, and variety of materials, rubber sealing rings are widely used in various mechanical equipment. Traditional rubber sealing rings are basically single-layer rubber sealing rings. However, single-layer rubber sealing rings have poor restoring elasticity. After long-term use, the rubber sealing rings will deform and be damaged due to reciprocating compression, which will affect the sealing performance of the rubber sealing rings and reduce their service life.

[0003] To overcome the above-mentioned defects, in the prior art 1 (Chinese patent application number CN202122134244.7, application date 2021-09-06), a high-elasticity engine sealing ring uses several rubber strips and a return spring to further improve the elasticity of the sealing ring body, thereby avoiding the problem of poor sealing performance due to insufficient elasticity of the sealing ring body. Although the prior art can improve the return and rebound performance of the rubber sealing ring and avoid deformation after prolonged compression, there is no support mechanism inside the rubber sealing ring to buffer and depressurize the reciprocating compression. After prolonged reciprocating compression, deformation and damage will still occur, reducing the practicality of the rubber sealing ring. Therefore, we propose a high-elasticity rubber sealing ring that can effectively solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a highly elastic rubber sealing ring to solve the problem mentioned in the background art that currently available rubber sealing rings do not have an internal support mechanism to buffer and depressurize the reciprocatingly compressed rubber sealing ring, resulting in deformation and damage after long-term reciprocating compression, thus reducing the practicality of the rubber sealing ring.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a highly elastic rubber sealing ring, comprising a sealing ring body and a gasket, wherein the gasket is disposed inside the sealing ring body, and the sealing ring body is hollow; a ring of elastic return balls is disposed on the upper and lower sides of the gasket, and the two rings of elastic return balls are equally spaced and symmetrically arranged about the transverse center line of the gasket.

[0006] Preferably, a reset cylinder is provided on the upper and lower sides of the gasket, and the two reset cylinders have the same structure, and an elastic reset ball is provided in the gap of each reset cylinder.

[0007] Preferably, both elastic return balls are made of rubber material.

[0008] Preferably, the outer sides of the two reset cylinders are respectively attached to the upper and lower sides of the inner wall of the sealing ring body, and the two reset cylinders are provided with buffer springs through internal slots.

[0009] Preferably, the inner side of the sealing ring body is provided with multiple anti-slip blocks, and each anti-slip block is equally spaced, and each anti-slip block is made of rubber material.

[0010] Preferably, the inner side of the sealing ring body is grooved with a rubber layer, a heat-resistant layer is attached above the rubber layer, an anti-oxidation layer is attached above the heat-resistant layer, and a corrosion-resistant layer is attached to the top of the anti-oxidation layer.

[0011] Preferably, a sealing layer is bonded to the bottom of the rubber layer, and a wear-resistant layer is bonded to the bottom of the sealing layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] (1) A gasket is provided. A gasket is provided in the groove inside the sealing ring body. Then, a ring of elastic reset balls is provided at equal angles on the upper and lower sides of the gasket. The gasket can not only increase the overall deformation resistance of the sealing ring body and avoid deformation of the sealing ring body under repeated compression in the later stage, but also increase the overall high elasticity of the sealing ring body through the two rings of elastic reset balls. This can prevent the sealing ring body from reducing its sealing performance due to long-term compression and improve the practicality of the sealing ring body.

[0014] (2) Furthermore, by using a ring of reset cylinders set at equal angles on the upper and lower sides of the gasket, and then attaching the upper and lower sides of the inner side of the sealing ring body to the outside of the two rings of reset cylinders, the plasticity of the sealing ring body can be increased by the two rings of reset cylinders, avoiding deformation of the sealing ring body after long-term compression and use, and improving the service life of the sealing ring body.

[0015] (3) Furthermore, by utilizing the slotted grooves inside the two reset cylinders, two buffer springs can be installed to increase the reset performance of the two reset cylinders themselves, so that the sealing ring body has a certain impact resistance and resilience.

[0016] (4) An anti-oxidation layer and a corrosion-resistant layer are provided. An anti-oxidation layer and a corrosion-resistant layer are respectively attached to the inner side of the top of the sealing ring body. Since the anti-oxidation layer and the corrosion-resistant layer are made of silicone rubber and neoprene rubber respectively, they can not only improve the anti-oxidation performance of the sealing ring body itself, but also improve the corrosion resistance performance of the sealing ring body itself, making it more practical.

[0017] (5) Furthermore, a sealing layer and a wear-resistant layer are respectively attached to the bottom outer side of the sealing ring body. Since the sealing layer and the wear-resistant layer are made of butyl rubber and polyurethane respectively, they can not only increase the sealing performance of the sealing ring body itself, but also increase the wear resistance of the sealing ring body itself, thereby improving the service life of the sealing ring body.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides the following technical solution:

[0027] Example 1: To address the issue that existing sealing ring bodies 1 lack internal support mechanisms to buffer and depressurize during reciprocating compression, resulting in deformation and damage after prolonged reciprocating compression and reduced usability, the following solution is disclosed: a sealing ring body 1 and a gasket 3, wherein the gasket 3 is disposed inside the sealing ring body 1, and the sealing ring body 1 is hollow; a ring of elastic return balls 5 is provided on the upper and lower sides of the gasket 3, and the two rings of elastic return balls 5 are equally spaced and symmetrically arranged about the transverse center line of the gasket 3.

[0028] A reset cylinder 4 is provided on the upper and lower sides of the gasket 3, and the two reset cylinders 4 have the same structure. An elastic reset ball 5 is provided in the gap of each reset cylinder 4. Both elastic reset balls 5 are made of rubber material. The outer sides of the two reset cylinders 4 are respectively attached to the upper and lower sides of the inner wall of the sealing ring body 1. The inner groove of the two reset cylinders 4 is provided with a buffer spring 6. Multiple anti-slip blocks 2 are provided on the inner side of the sealing ring body 1. Each anti-slip block 2 is equally spaced and each anti-slip block 2 is made of rubber material.

[0029] like Figures 1-5 As shown, while the sealing ring body 1 is practical, the gasket 3 inside the sealing ring body 1 can increase its own deformation resistance, preventing the sealing ring body 1 from deforming under repeated compression. Then, the elastic return balls 5 set on the upper and lower sides of the gasket 3 can also increase the overall high elasticity of the sealing ring body 1, improving its practicality and preventing the sealing ring body 1 from failing to rebound after long-term use. At this time, the two return cylinders 4 will also increase the return performance of the sealing ring body 1 through the two buffer springs 6, giving the sealing ring body 1 a certain impact resistance and rebound performance. Finally, the multi-row anti-slip sliders 2 can increase the anti-slip performance of the sealing ring body 1, improving its service life.

[0030] Example 2, unlike Example 1, discloses that the overall service life of the sealing ring body 1 can be increased by using an anti-oxidation layer 9, a corrosion-resistant layer 10, a sealing layer 11, and a wear-resistant layer 12.

[0031] A rubber layer 7 is provided with a groove on the inner side of the sealing ring body 1, and a heat-resistant layer 8 is attached to the top of the rubber layer 7, and an anti-oxidation layer 9 is attached to the top of the heat-resistant layer 8, and a corrosion-resistant layer 10 is attached to the top of the anti-oxidation layer 9; a sealing layer 11 is attached to the bottom of the rubber layer 7, and a wear-resistant layer 12 is attached to the bottom of the sealing layer 11.

[0032] like Figures 1-6As shown, while the sealing ring body 1 is in use, the heat-resistant layer 8 increases the heat resistance of the sealing ring body 1, preventing it from spontaneously combusting due to high temperature. The anti-oxidation layer 9 and the corrosion-resistant layer 10 further enhance the anti-oxidation and corrosion resistance of the sealing ring body 1, thus improving its service life. Finally, the sealing layer 11 and the wear-resistant layer 12 further enhance the sealing performance and wear resistance of the sealing ring body 1, thus improving its service life.
