Description

Technical Field

[0001] The utility model belongs to the field of hydraulic parts, and particularly relates to an anti-shake hydraulic pipe fitting. Background Art

[0002] Hydraulic fittings are mainly used to transport pressurized liquids. During use, the pressurized liquid sometimes accelerates through the hydraulic fittings, causing the hydraulic fittings to shake. Long-term shaking may cause the connections between the hydraulic fittings to loosen, causing the pressurized liquid to leak. Summary of the invention

[0003] The purpose of the utility model is to provide an anti-shake hydraulic pipe fitting in view of the above problems existing in the prior art.

[0004] The purpose of the utility model can be achieved through the following technical solutions: an anti-shake hydraulic pipe fitting, comprising an outer pipe and an inner pipe, characterized in that a plurality of fixing strips for fixing the inner pipe are arranged on the outer wall of the inner pipe, and elastic columns for supporting the fixing strips are arranged between the fixing strips and the inner wall of the outer pipe;

[0005] The fixing strips are interconnected and fit the inner tube in a circular arrangement. An inwardly recessed groove is provided on one side of the fixing strip, and a mating portion that protrudes outward and can interact in the groove is provided on the other side of the fixing strip. A protrusion is provided on the mating portion, and a limiting portion for limiting the protrusion is provided at the notch of the groove, and an elastic element with an elastic reset function is provided between the protrusion and the limiting portion.

[0006] In the above-mentioned anti-shake hydraulic pipe fitting, the inner tube is made of rubber material and has good shrinkage.

[0007] In the above-mentioned anti-shake hydraulic pipe fitting, a sleeve for cooperating with an elastic column is arranged on the inner wall of the outer tube, one end of the elastic column penetrates into the sleeve, and the elastic column can slide up and down in the sleeve, and the sleeve is filled with elastic material.

[0008] In the above-mentioned anti-shake hydraulic pipe fitting, the elastic material is a slowly reset elastic sponge.

[0009] Compared with the prior art, the anti-shake hydraulic pipe fitting can reduce the force generated when the pressurized liquid passes through at an accelerated speed by expanding and contracting the inner tube, thereby effectively alleviating the shaking problem of the hydraulic pipe fitting. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a cross-sectional view of the hydraulic pipe fitting for anti-shake;

[0011] Figure 2 It is a top view of the hydraulic pipe fitting of the anti-shake device.

[0012] In the figure, 1, outer tube; 2, inner tube; 3, fixing strip; 4, elastic column; 5, groove; 6, matching part; 7, raised part; 8, limiting part; 9, elastic element; 10, sleeve; 11, elastic material. DETAILED DESCRIPTION

[0013] 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.

[0014] like Figure 1 , Figure 2 As shown, the anti-shake hydraulic pipe fitting comprises an outer pipe 1 and an inner pipe 2, a plurality of fixing bars 3 for fixing the inner pipe 2 are arranged on the outer wall of the inner pipe 2, and elastic columns 4 for supporting the fixing bars 3 are arranged between the fixing bars 3 and the inner wall of the outer pipe 1;

[0015] The fixing strips 3 are connected to each other and fit the inner tube 2 in a circular arrangement. A groove 5 recessed inwardly is provided on one side of the fixing strip 3. A matching portion 6 protruding outwardly and capable of interacting in the groove 5 is provided on the other side of the fixing strip 3. A protruding portion 7 is provided on the matching portion 6. A limiting portion 8 for limiting the protruding portion 7 is provided at the notch of the groove 5. An elastic element 9 with an elastic reset function is provided between the protruding portion 7 and the limiting portion 8.

[0016] A sleeve 10 for cooperating with the elastic column 4 is arranged on the inner wall of the outer tube 1 . One end of the elastic column 4 goes deep into the sleeve 10 , and the elastic column 4 can slide up and down in the sleeve 10 . The sleeve 10 is filled with elastic material 11 .

[0017] During use, when the pressure liquid passes through the inner tube 2 quickly, the force generated instantly will stretch the inner tube 2 open, and at the same time drive the fixing strip 3 to separate, so that the protrusion 7 continues to approach the limit portion 8, and at the same time the elastic element 9 is squeezed and contracted, and in this action it absorbs part of the force generated by the pressure liquid. While the inner tube 2 expands, it drives the fixing strip 3 to expand outward, and the fixing strip 3 pushes the elastic column 4 into the sleeve 10, and performs secondary force unloading through the elastic material 11 in the sleeve 10.

[0018] To elaborate further, the inner tube 2 is made of rubber and has good shrinkage.

[0019] To further elaborate, the elastic material 11 is a slowly restoring elastic sponge, which will slowly restore after contraction to prevent rapid restoration when subjected to continuous force and cause collision of two forces.

[0020] 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.

[0021] Although the terminology such as outer tube 1, inner tube 2, fixing strip 3, elastic column 4, groove 5, matching portion 6, protrusion 7, limiting portion 8, elastic element 9, sleeve 10, elastic material 11 is used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for the purpose of more conveniently describing and explaining the essence of the utility model; interpreting them as any additional limitation is contrary to the spirit of the utility model.
