Description

Technical Field

[0001] This utility model relates to the field of sealing rings, and more particularly to a combined sealing ring. Background Technology

[0002] A sealing ring is a ring-shaped part used to seal fluids or gases in mechanical equipment. It is usually made of elastic material and can be placed between two mating parts to prevent fluid or gas leakage. Sealing rings are commonly used in automobiles, mechanical equipment, pipeline systems and other fields to ensure normal equipment operation and reduce energy waste. There are many types and shapes of sealing rings, and it is very important to select the appropriate sealing ring according to different application scenarios and needs.

[0003] A search revealed Chinese Patent Publication No. CN219655246U, which discloses a combined sealing ring. The ring includes a first sealing ring with an anti-detachment component on one side and a thickening component on the other. By incorporating a spiral blade, the connection between the first sealing ring and the pipe is made tighter during installation, and the first sealing ring is prevented from detaching during pipe disassembly, thus preventing loss. By aligning a connecting ring with an annular groove and inserting it into the groove, pressing down on the second sealing ring causes it to push the connecting ring. When the connecting ring abuts against the inside of the annular groove, a protrusion engages with the limiting groove, fixing the position of the second sealing ring. This thickening of the first sealing ring enhances its usability and practicality.

[0004] The aforementioned device, due to its structural design, can only perform a single thickening operation on the first sealing ring, making it unable to better adjust the thickness of the sealing ring according to actual conditions. Furthermore, the first and second sealing rings are only connected by a connecting ring and a protrusion in the middle, which causes deformation of the inner and outer sides of the sealing rings under pressure, resulting in oil stains and other impurities flowing to the connecting ring and the annular groove, thus affecting the connection between the two sealing gaskets. It is not practical enough to propose a combined sealing ring to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a combined sealing ring, which aims to improve the existing technology where the seal can only be thickened once, and where the deformation of the inner and outer sides of the sealing ring during compression causes it to flow to the connecting ring and the annular groove, thus affecting the connection between the two sealing gaskets.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a combined sealing ring, comprising a sealing ring body, the sealing ring body comprising a connecting component, a first connecting member being provided at the upper part of the connecting component, a second connecting member being provided at the lower part of the connecting component, a support ring being provided between the connecting component and the first connecting member and between the connecting component and the second connecting member, and the connecting component comprising a main ring.

[0013] As a further description of the above technical solution:

[0014] The second connector includes a second sealing gasket. A fourth convex ring is fixedly connected to the top of the second sealing gasket. The fourth convex ring is movably connected to a fourth concave ring groove. Two second retaining rings are fixedly connected to the top of the second sealing gasket. The two second retaining rings are movably connected to the second ring groove. A second concave ring groove is formed on the top surface of the second sealing gasket, and the second convex ring is movably connected to it.

[0015] As a further description of the above technical solution:

[0016] The top surface of the second sealing gasket has a third slot, and the support ring is movably connected to it.

[0017] As a further description of the above technical solution:

[0018] A first inclined ring is fixedly connected to the upper part of the first retaining ring near the support ring. A first limiting groove is opened on the upper part of the first ring groove, and the first inclined ring is movably connected to it.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting the connecting components to cooperate with the first connecting piece and the second connecting piece, and by setting the convex rings to cooperate with the concave ring grooves, multiple connecting components can be connected end to end to change the thickness of the sealing ring.
