Description

Technical Field

[0001] The utility model belongs to the field of hydraulic parts, and particularly relates to a noise-reducing hydraulic part. Background Art

[0002] Hydraulic parts are components of the hydraulic system. When the hydraulic parts are working, the medium often needs to pass through the hydraulic parts. During the flow of the medium, since the medium is pushed by high pressure, it is easy for the medium to cause the hydraulic parts to vibrate when passing through the hydraulic parts. The vibration of the hydraulic parts is easy to make noise, which may cause physical and mental damage to the personnel operating the hydraulic parts. Summary of the invention

[0003] The purpose of the utility model is to provide a noise reduction hydraulic component in view of the above problems existing in the prior art.

[0004] The purpose of the utility model can be achieved by the following technical solutions: A noise reduction hydraulic component, comprising a pipe fitting 1 and a pipe fitting 2 that can be mutually engaged, characterized in that a clamping portion for inserting into the pipe fitting 2 is provided at one end of the pipe fitting 1, and a limiting portion 1 with a limiting function is provided between the pipe fitting 1 and the clamping portion;

[0005] One end of the second pipe is provided with a matching groove for matching the clamping part, and the outer side of the matching groove is provided with a second limiting part for abutting against the first limiting part;

[0006] The pipe fittings 1 and 2 are both provided with a plurality of support columns for supporting the inner and outer walls of the pipe fittings 1 and 2, and a plurality of counterweight blocks are provided beside the support columns.

[0007] In the above-mentioned noise reduction hydraulic component, elastic elements for providing elastic force and having elastic reset function are arranged on both sides of the counterweight block. One end of the elastic element is connected to pipe fittings 1 and 2, and the other end is connected to the counterweight block.

[0008] In the above-mentioned noise reduction hydraulic component, an elastic rubber pad is provided at the intersection of the clamping portion and the limiting portion.

[0009] In the above-mentioned noise reduction hydraulic component, a second rubber pad is provided at the intersection of the matching groove and the second limiting portion.

[0010] Compared with the prior art, the noise-reducing hydraulic component reduces the vibration of the hydraulic component by the vibration of the elastic element and the counterweight when the medium passes through the pipe, thereby reducing the noise. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] 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.

[0015] like Figure 1 , Figure 2 As shown, the noise reduction hydraulic component includes a pipe 1 and a pipe 2 that can be mutually engaged, a clamping portion 3 for inserting into the pipe 2 is provided at one end of the pipe 1, and a limiting portion 4 with a limiting function is provided between the pipe 1 and the clamping portion 3;

[0016] A matching groove 5 for matching the clamping portion 3 is provided at one end of the second pipe fitting 2, and a second limiting portion 6 for abutting against the first limiting portion 4 is provided outside the matching groove 5;

[0017] Several support columns 7 for supporting the inner and outer walls of pipe fittings 1 and 2 are arranged inside pipe fittings 1 and 2, and several counterweight blocks 8 are arranged next to the support columns 7. Elastic elements 9 for providing elastic force and having elastic reset function are arranged on both sides of the counterweight blocks 8. One end of the elastic element 9 is connected to pipe fittings 1 and 2, and the other end is connected to the counterweight block 8.

[0018] When in use, the medium passes through pipe fitting 1 and pipe fitting 2, and vibration is generated when the medium flows through, which drives the inner wall of pipe fitting 1 and pipe fitting 2 to vibrate, and at the same time drives the counterweight block 8 to shake. When the counterweight block 8 shakes, the elastic element 9 will reduce the force generated by the vibration through continuous elastic reset, so that pipe fitting 1 and pipe fitting 2 reduce vibration, thereby reducing noise.

[0019] To be more specific, an elastic rubber pad 10 is provided at the junction of the clamping portion 3 and the limiting portion 4.

[0020] To further elaborate, a rubber pad 11 is provided at the junction of the matching groove 5 and the limiting portion 6 .

[0021] After the pipe fitting 1 and the pipe fitting 2 are clamped together, the friction and collision between the clamping part 3 and the matching groove 5 are reduced by the rubber pad 10 and the rubber pad 2 11 at the contact point between the clamping part 3 and the matching groove 5.

[0022] 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.

[0023] Although this article uses more terms such as pipe fitting 1, pipe fitting 2, clamping part 3, limit part 1, matching groove 5, limit part 2, support column 7, counterweight block 8, elastic element 9, rubber pad 10, rubber pad 2 11, etc., it does not exclude the possibility of using other terms. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
