Description

Technical Field

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

[0002] A rubber sealing ring is a ring-shaped device made of rubber material, which is usually used to seal the transmission of liquids or gases to prevent fluid leakage and environmental pollution. It is widely used in various fields such as machinery, automobiles, electronics, medical, and construction.

[0003] Existing patent application number: 202120829643.2 A rubber sealing ring includes an inner ring, an outer ring connected to the outside of the inner ring, a waterproof layer on the outer surface of the outer ring, a corrosion-resistant layer on the outer surface of the waterproof layer, and a wear-resistant layer on the outer surface of the corrosion-resistant layer.

[0004] The aforementioned patent describes a rubber sealing ring. In actual use, the installation method of the sealing ring is fixed, relying solely on its own elasticity for elastic fitting. Under long-term working conditions, the sealing quality will be affected as the elasticity of the sealing ring decreases. The installation structure is relatively simple, and the explosion-proof performance needs to be improved. Therefore, we propose an elastic rubber bidirectional sealing ring to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a bidirectional sealing ring made of elastic rubber to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a bidirectional elastic rubber sealing ring, comprising a reinforced sealing mechanism, wherein the reinforced sealing mechanism comprises a sealing ring body and an annular cavity, the top surface of the sealing ring body having an annular cavity, the ring portion of the sealing ring body located outside the annular cavity being an outer ring body, the ring portion of the sealing ring body located inside the annular cavity being an inner ring body, the surface of the sealing ring body having a sleeve groove, a hoop being fitted inside the sleeve groove, a connecting sleeve being installed at the first end of the hoop, a screw being rotatably installed inside the connecting sleeve, the screw passing through both ends of the connecting sleeve, a nut being connected to the first end of the screw, and a threaded hole being opened at the end of the hoop, the screw being threadedly screwed into the inner side of the threaded hole.

[0007] Preferably, the inner wall of the annular cavity is provided with anti-slip texture.

[0008] Preferably, the upper and lower edges of the socket groove surface are connected with limiting bands, and the limiting bands are arranged at equal intervals on the socket groove surface.

[0009] Preferably, the height of the socket groove corresponds to that of the annular cavity.

[0010] Preferably, the length of the threaded section of the screw is not less than 10 mm.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention features a reinforced sealing mechanism. By tightening the nut, the screw pulls the two ends of the clamp band closer together, thus adjusting the clamp band to a tightened state. At this point, the clamp band is tightly secured inside the sleeve groove and clamps the annular cavity from the outside, ensuring that the sealing ring body is tightly fitted onto the port surface. The tight installation is achieved through the elasticity of the sealing ring body itself and the clamping action of the clamp band, greatly improving the installation firmness between the sealing ring body and the port and ensuring the sealing performance of the sealing ring body.

[0013] This invention features a limiting band connected to the upper and lower edges of the socket groove surface. The limiting band ensures that the clamp is engaged with the socket groove, preventing the clamp from falling off or being lost. Attached Figure Description

[0016] Figure 3 This is a schematic diagram of the hoop structure in this utility model.

[0017] In the diagram: reinforced sealing mechanism-1, sealing ring body-11, annular cavity-12, outer ring body-13, inner ring body-14, sleeve groove-15, limiting band-15a, hoop band-16, connecting sleeve-17, screw-18, nut-19, threaded hole-110. Detailed Implementation

[0018] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0019] Please see Figure 1-2This utility model provides a bidirectional elastic rubber sealing ring, including a reinforced installation sealing mechanism 1. The reinforced installation sealing mechanism 1 includes a sealing ring body 11, an annular cavity 12, an outer ring body 13, an inner ring body 14, a sleeve groove 15, a hoop 16, a connecting sleeve 17, a screw 18, a nut 19, and a threaded hole 110. The sealing ring body 11 has an annular cavity 12 on its top surface. The inner wall of the annular cavity 12 is provided with anti-slip texture to improve the installation firmness of the sealing ring body 11 and prevent the sealing ring body 11 from sliding and loosening. The ring portion of the sealing ring body 11 located outside the annular cavity 12 is the outer ring body 13. The inner ring body 14 is located inside the annular cavity 12. The sealing ring body 11 has a sleeve groove 15 on its surface. The sleeve groove 15 is annular. A hoop 16 is fitted inside the sleeve groove 15. The height of the sleeve groove 15 corresponds to that of the annular cavity 12, so that the hoop 16 can clamp and tighten the annular cavity 12 from the outside, improving the installation firmness of the annular cavity 12 and the port connector. Limiting bands 15a are connected to the upper and lower edges of the surface of the sleeve groove 15. The limiting bands 15a are equidistantly arranged on the surface of the sleeve groove 15. The limiting bands 15a can keep the hoop 16 fitted with the sleeve groove 15, preventing the hoop 16 from falling off and being lost.

[0020] Please see Figure 3 This utility model provides an elastic rubber bidirectional sealing ring. A connecting sleeve 17 is installed at the first end of the band 16. A screw 18 is rotatably installed inside the connecting sleeve 17. The screw 18 passes through both ends of the connecting sleeve 17. A nut 19 is connected to the first end of the screw 18. A threaded hole 110 is opened at the end of the band 16. The screw 18 is threaded into the inner side of the threaded hole 110. The length of the threaded section of the screw 18 is not less than 10mm to ensure that the band 16 has sufficient tension adjustment range.

[0021] Specifically, before use, first loosen the nut 19, and the screw 18 pushes and opens the two ends of the band 16 through the threaded hole 110, so that the band 16 is adjusted to a relaxed state, ensuring that the sealing ring body 11 can be installed smoothly;

[0022] In use, the sealing ring body 11 is fitted and installed with the port connector through the annular cavity 12. At this time, the inner ring body 14 is elastically filled into the inside of the port, and the outer ring body 13 is elastically wrapped around the outside of the port. The double-layer sealing connection can prevent the medium from leaking from the inside to the outside, and can also prevent the external medium from entering the inside, thereby achieving bidirectional sealing.

[0023] After the sealing ring body 11 is initially installed, tighten the nut 19 so that the screw 18 pulls the two ends of the clamp 16 closer together, thereby adjusting the clamp 16 to a tightened state. At this time, the clamp 16 is clamped on the inner side of the sleeve groove 15 and clamps the annular cavity 12 from the outside, so that the sealing ring body 11 is tightly fitted on the port surface. The tight installation is achieved by the elasticity of the sealing ring body 11 itself and the clamping effect of the clamp 16, which greatly improves the installation firmness of the sealing ring body 11 and the port and ensures the sealing performance of the sealing ring body 11.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
