Description

Technical Field

[0001] The present application relates to the technical field of sealing rings, and in particular to a wear-resistant D-shaped sealing ring. Background Art

[0002] D-type seals are mostly used for connection sealing of quick-release joints, but because the two ends may need to move back and forth during use, the two ends of the connection may twist.

[0003] The twisted connection end generates friction with the sealing ring, and defects such as breakage and tearing may occur on both sides of the sealing ring. However, such defects require disassembly and inspection, which is very cumbersome and therefore often overlooked. In response to the above-mentioned related technologies, the applicant believes that a sealing ring that can not only improve wear resistance but also facilitate inspection is proposed, thereby effectively avoiding wear and leakage. Utility Model Content

The reinforcement plate is accommodated on the side of the rubber ring body close to the inner ring, and the reinforcement plate is bent and extended along the direction of the rubber ring body. The reinforcement plate is elastic; the reinforcement ring is accommodated on the side of the rubber ring body close to the outer ring.

[0009] By adopting the above technical solution, the dual configuration of the reinforcement plate and the reinforcement ring forms a comprehensive support system from the inside to the outside of the rubber ring body, significantly enhancing the sealing ring's ability to resist high pressure and mechanical stress.

[0010] Preferably, the adsorption structure includes an adsorption groove, an air guide tube, a one-way air guide port and an air guide cavity, the adsorption groove is arranged at intervals on the side wall of the rubber ring body; the air guide cavity is arranged on the inner side of the reinforcement ring; one end of the air guide tube is connected to the bottom end of the air guide cavity, and the other end extends and is connected to the top of the adsorption groove; the one-way air guide port is accommodated in the air guide tube, and the one-way air guide port extends from one side of the adsorption groove toward the air guide cavity.

[0011] By adopting the above technical solution, the adsorption structure design not only enhances the adaptability and functionality of the sealing ring through its precise gas management system, but also does not affect the sealing effect of the rubber ring body.

[0012] Preferably, the side walls of the liquid guide groove abut against each other, and the liquid guide groove is arranged through the inner ring reinforcement sealing rib; when the rubber ring body is twisted in a plane on one side of the reinforcement sealing rib, gaps are generated on the two side walls of the liquid guide groove.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] By providing an adsorption structure on one side of the rubber ring body and forming an elastic cavity, it can be more tightly adsorbed to the surface of the part, thus preventing wear on both sides.

[0021] The present application is further described in detail below with reference to the accompanying drawings.

[0022] The present application discloses a wear-resistant D-shaped sealing ring. Figure 1 、 2 , including a rubber ring body 1, an adsorption structure 2 is provided on one side of the rubber ring body 1, and the rubber ring body 1 is adsorbed on the surface of one part through the adsorption structure 2, thereby preventing the adsorption side from being worn. The inner and outer rings of the rubber ring body 1 are provided with a radially hard outer wall reinforcement structure 5. The outer wall reinforcement structure 5 prevents the lateral deformation of the rubber ring body 1, so that it has better pressure resistance. The wall reinforcement structure includes a reinforcement plate 51 and a reinforcement ring 52. The reinforcement plate 51 is accommodated on the side of the rubber ring body 1 close to the inner ring, and the reinforcement plate is bent and extended along the direction of the rubber ring body 1. The reinforcement plate 51 is elastic; the reinforcement ring 52 is accommodated on the side of the rubber ring body 1 close to the outer ring.

[0023] Reference Figure 1 、 2 The adsorption structure 2 includes an adsorption groove 21, an air guide tube 22, a one-way air guide port 24 and an air guide cavity 23. The adsorption groove 21 is spaced apart and arranged on the side wall of the rubber ring body 1; the air guide cavity 23 is arranged on the inner side of the reinforcement ring 52; one end of the air guide tube 22 is connected to the bottom end of the air guide cavity 23, and the other end extends and is connected to the top of the adsorption groove 21; the one-way air guide port 24 is accommodated in the air guide tube 22, and the one-way air guide port 24 extends from one side of the attachment groove 21 toward the air guide cavity 23.

[0024] Reference Figure 1 、 2 When the adsorption groove 21 is pressurized, the air in the adsorption groove 21 enters the air guide cavity 23 along the air guide pipe 22 from the one-way air guide port 24, so that the adsorption groove 21 can smoothly discharge the air and generate negative pressure. At the same time, the gas will not overflow to the two sides of the rubber ring body 1, thereby causing a loose seal and leakage. The rubber ring body 1 is pressurized and attached to the surface that is not often disassembled. By disassembling the other side, the wear condition of the gasket can be directly judged, and the inspection of the other side of the rubber ring body 1 can be omitted.

[0025] Reference Figure 1 、 2 At the same time, the one-way air guide port 24 can increase the gas storage pressure in the air guide cavity 23, so that the air in the adsorption tank 21 can be stored multiple times, which can cope with multiple squeezing and vibration situations and achieve better adsorption effect.

[0026] Reference Figure 1 、 2The side of the rubber ring body 1 relative to the adsorption structure 2 is provided with a reinforcing sealing rib 3 protruding from the side wall of the rubber ring body 1. The reinforcing sealing rib 3 is arranged in a ring shape and nested. The inner ring of the reinforcing sealing rib 3 is arranged close to the middle position of the side wall of the rubber ring body 1, and the outer ring of the reinforcing sealing rib 3 is arranged close to the outer ring of the side wall of the rubber ring body 1; the middle of the rubber ring body 1 is softest. By adding the reinforcing sealing rib 3, the wear resistance of the rubber ring body 1 is increased while the reinforcing sealing rib 3 obtains the elasticity of the rubber ring body 1, thereby obtaining a better sealing effect. The outer ring reinforcing sealing rib 3 corresponds to the outer ring of the rubber ring body 1. The outer ring of the rubber ring body 1 is usually accommodated on the inner side of the component, which is drier and more susceptible to wear. Better strength is obtained by reinforcing the sealing rib 3.

[0027] Reference Figure 1 、 2 A bent liquid guide groove 4 is provided between the inner ring of the rubber ring body 1 near the side of the reinforced sealing rib 3 and the two reinforced sealing ribs 3; the side walls of the liquid guide groove 4 abut against each other, and the liquid guide groove 4 is provided through the inner ring reinforced sealing rib 3; when a plane torsion occurs between the connecting parts on both sides of the rubber ring body 1, the adsorption groove 21 causes the rubber ring body 1 to be adsorbed on one side of the connecting part, and the other side connecting part and the rubber ring body 1 are twisted in the plane on the side of the reinforced sealing rib 3. The torsion causes the upper surface of the rubber ring body 1 to deform, thereby creating gaps on both side walls of the liquid guide groove 4. The liquid can penetrate along the liquid guide groove 4 to both sides of the inner ring reinforced sealing rib 3, thereby properly lubricating the rubber ring body 1 and preventing dry grinding.

[0028] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
