Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic pressure, in particular to a double anti-drop structure for a hydraulic joint and a hydraulic hose. Background Art

[0002] A hydraulic joint is a fitting that connects different hydraulic components to form a closed-loop hydraulic system. The hydraulic hose is also known as hydraulic oil pipe, hydraulic hose, high-pressure hose, hydraulic pipe, steel wire high-pressure pipe, steel wire braided hose and wire spiral hose. It is generally divided into steel wire braided hydraulic hose and steel wire spiral hydraulic hose.

[0003] When the hydraulic joint and the hydraulic hose are connected, an anti-slip structure is required to prevent the connection between the hydraulic joint and the hydraulic hose from falling off. However, in the prior art, most anti-slip structures can only play a single anti-slip effect. Since the hydraulic joint and the hydraulic hose are often affected by external forces such as pulling and vibration, it is difficult to achieve the anti-slip purpose between the two with only a single anti-slip structure, thereby affecting the stability of the connection between the hydraulic joint and the hydraulic hose. Utility Model Content

[0004] The utility model aims to provide a double anti-drop structure for a hydraulic joint and a hydraulic hose, so as to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double anti-slip structure for a hydraulic joint and a hydraulic hose, comprising a hydraulic joint body, a hydraulic hose body and an anti-slip assembly; the hydraulic hose body is connected to the hydraulic joint body through the anti-slip assembly; wherein the anti-slip assembly comprises a threaded block, a threaded barrel, a movable groove, a movable ring, a spring and a connecting block; two of the threaded blocks are symmetrically fixed on both sides of the hydraulic joint body; the threaded barrel is fixedly connected to the end of the hydraulic hose body; wherein the threaded block is threadedly connected to the threaded barrel; a movable groove is provided in the hexagonal block of the hydraulic joint body; the movable ring is slidably arranged in the movable groove; the two ends of the spring are fixedly connected to the inner wall of the movable groove and the movable ring respectively; a plurality of the connecting blocks are fixed in an annular array on the side of the movable ring away from the spring, and the end of the connecting block extends through the movable groove to the outside and contacts with the threaded barrel.

[0006] As a preferred embodiment, the connecting block is in a truncated cone structure, and the size of the connecting block on a side close to the movable ring is larger than the size of the connecting block on a side away from the movable ring.

[0007] As a preferred embodiment, it further comprises an elastic component; the elastic component is arranged on the threaded block.

[0008] As a preferred embodiment, the elastic component includes a receiving groove, a sealing ring and an extrusion groove; the threaded block is provided with a receiving groove on the side away from the hydraulic joint body; the sealing ring is movably arranged in the receiving groove; the threaded barrel is provided with an extrusion groove; wherein the sealing ring is in contact with the inner wall of the extrusion groove.

[0009] As a preferred embodiment, the accommodating groove is an annular structure, and the cross section of the accommodating groove is a major arc structure.

[0010] As a preferred embodiment, the cross section of the sealing ring is an elliptical structure.

[0011] As a preferred embodiment, the extrusion groove is an annular structure, the cross section of the extrusion groove is a minor arc structure, and the extrusion groove and the accommodating groove constitute a sealing ring accommodating chamber.

[0012] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0013] The double anti-slipping structure of the hydraulic joint and the hydraulic hose is provided with an anti-slipping component. When the hydraulic joint body and the hydraulic hose body are connected, first, the threaded barrel is sleeved on the threaded block, and the threaded block is threadedly connected to the threaded barrel, so as to realize the initial anti-slipping effect of the hydraulic joint body and the hydraulic hose body, until the threaded barrel contacts the connecting block. At this time, the threaded connection between the threaded block and the threaded barrel will cause the threaded barrel to squeeze the connecting block, so that the movable ring slides in the movable groove, so that the spring is forced to contract, so that the spring is forced to contract to generate a relative force, so that the tooth groove in the threaded barrel squeezes the thread on the threaded block, and the stability of the threaded connection between the threaded block and the threaded barrel is improved. In addition, the hydraulic joint body and the hydraulic hose body are anti-slipping again, until the end face of the threaded barrel contacts the side face of the hexagonal block of the hydraulic joint body. The double anti-slipping structure is formed by the anti-slipping component, which can greatly improve the connection strength between the hydraulic joint body and the hydraulic hose body and the anti-pulling and anti-vibration capabilities.

[0014] The hydraulic joint and the hydraulic hose have a double anti-slip structure, and by arranging a receiving groove, a sealing ring and an extrusion groove, when the threaded barrel extrudes the connecting block, the extrusion groove will squeeze the sealing ring, so that the sealing ring is squeezed into a compressed state, and the relative force generated by the extrusion of the sealing ring will cause the threads on the threaded block to squeeze the tooth grooves in the threaded barrel, further improving the stability of the threaded connection between the threaded block and the threaded barrel.

[0030] The utility model provides an anti-slip assembly 3. When the hydraulic joint body 1 and the hydraulic hose body 2 are connected, first, the threaded barrel 302 is sleeved on the threaded block 301, and the threaded block 301 is threadedly connected with the threaded barrel 302, so as to achieve a preliminary anti-slip effect on the hydraulic joint body 1 and the hydraulic hose body 2, until the threaded barrel 302 contacts the connecting block 306. At this time, the threaded connection between the threaded block 301 and the threaded barrel 302 will cause the threaded barrel 302 to squeeze the connecting block 306, so that the movable ring 304 slides in the movable groove 303, so that the spring 305 The spring 305 is forced to contract and generate a relative force, so that the groove in the threaded barrel 302 squeezes the thread on the threaded block 301, thereby improving the stability of the threaded connection between the threaded block 301 and the threaded barrel 302, and realizing the anti-slip effect of the hydraulic joint body 1 and the hydraulic hose body 2 again, until the end face of the threaded barrel 302 contacts the side of the hexagonal block of the hydraulic joint body 1, and a double anti-slip structure is formed by the anti-slip component 3, which can greatly improve the connection strength between the hydraulic joint body 1 and the hydraulic hose body 2 as well as the anti-pulling and anti-vibration capabilities.

The tooth groove squeezes the threads on the threaded block 301, thereby improving the stability of the threaded connection between the threaded block 301 and the threaded barrel 302, and realizing the anti-dropping effect of the hydraulic joint body 1 and the hydraulic hose body 2 again. In the process of the threaded barrel 302 squeezing the connecting block 306, the extrusion groove 403 squeezes the sealing ring 402, so that the sealing ring 402 is squeezed into a compressed state, and the relative force generated by the squeezing of the sealing ring 402 causes the threads on the threaded block 301 to squeeze the tooth groove in the threaded barrel 302, further improving the stability of the threaded connection between the threaded block 301 and the threaded barrel 302, until the end face of the threaded barrel 302 contacts the side of the hexagonal block of the hydraulic joint body 1.
