A positioning protrusion is arranged between every two adjacent positioning grooves, the positioning ring is of a conical structure, the rubber ring is a conical ring matched with the positioning ring, and a plurality of sealing protrusions extending into the positioning grooves are formed in the rubber ring. The sealing device has the advantages that the rubber ring positioning effect is good, and the sealing effect is improved.

Description

Technical Field

[0001] The utility model belongs to the technical field of joints and relates to a damping joint, in particular to a hydraulic pipe damping joint. Background Art

[0002] The existing damping joint is provided with a rubber gasket. After the pipe is connected, the rubber gasket is located between the pipe and the joint to achieve a sealing effect. However, the existing rubber gasket structure is mostly flat, and its structural molding is relatively simple. After being provided, its position is unstable, which affects the sealing effect. Summary of the invention

[0003] The utility model aims to solve the above problems existing in the prior art and provides a hydraulic pipe damping joint which has stable installation and improved sealing effect.

[0004] The purpose of the utility model can be achieved through the following technical solutions: A hydraulic pipe damping joint, including a joint body with external threads at both ends, characterized in that the joint body is provided with an intermediate disk, a rubber ring is sleeved on the side of the intermediate disk and located on the joint body, a positioning ring for positioning and installing the rubber ring is provided on the joint body and integrally connected with the intermediate disk, a plurality of positioning grooves are provided on the positioning ring, a positioning protrusion is provided between two adjacent positioning grooves, and the positioning ring is a conical structure, the rubber ring is a conical ring matching the positioning ring, and the rubber ring is provided with a plurality of sealing protrusions extending into the positioning grooves.

[0005] In the above-mentioned hydraulic pipe damping joint, both ends of the joint body are threadedly connected with pipe fittings.

[0006] Compared with the prior art, the hydraulic pipe damping joint has the advantages of good positioning effect on the rubber ring and thus improving the sealing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0012] like Figure 1 , Figure 2 , Figure 3 As shown, the hydraulic pipe damping joint comprises a joint body 1 with external threads at both ends, an intermediate disk 2 is provided on the joint body 1, a rubber ring 3 is sleeved on the side of the intermediate disk 2 and located on the joint body 1, a positioning ring 4 for positioning and installing the rubber ring 3 is provided on the joint body 1 and integrally connected with the intermediate disk 2, a plurality of positioning grooves 5 are provided on the positioning ring 4, a positioning protrusion 6 is provided between two adjacent positioning grooves 5, and the positioning ring 4 is a conical structure, the rubber ring 3 is a conical ring matching the positioning ring 4, a plurality of sealing protrusions 7 extending into the positioning grooves 5 are provided on the rubber ring 3, and the rubber ring 3 is sleeved, and each sealing protrusion 7 is inserted into the corresponding positioning groove 5 through self-friction, so that it is radially positioned and not easy to fall off, and a plurality of sealing protrusions 7 can effectively achieve efficient sealing.

[0013] To be more specific, both ends of the joint body 1 are threadedly connected with pipe fittings, which are pressed tightly on the rubber ring 3 after being connected, so that the rubber ring 3 is axially limited to improve the sealing performance.

[0014] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0015] Although the present invention uses the terms such as joint body 1, intermediate disk 2, rubber ring 3, positioning ring 4, positioning groove 5, positioning convex 6, sealing convex 7, etc. more frequently, it does not exclude the possibility of using other terms. The use of these terms is only for the purpose of more conveniently describing and explaining the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.
