[0003] However, existing hydraulic hose fittings have certain shortcomings in sealing performance. Common fitting sealing structures are prone to sealing failure when faced with high pressure, high frequency vibration and complex working conditions, resulting in hydraulic oil leakage. This not only wastes energy and pollutes the working environment, but may also cause equipment failure and affect production safety. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention provides a high-sealing hydraulic hose connector, including a hose body, a connector assembly movably connected to the side surface of the hose body, the connector assembly including a connecting support tube, an outer fixing tube and a nut, a first sealing ring movably connected to the side surface of the hose body, a sealing ring provided on the inner side wall of the first sealing ring, and an opening provided on the side surface of the outer fixing tube.

[0005] Through the above technical solution, the multi-seal structure design of the first sealing ring and the sealing ring can effectively cope with complex working conditions such as high pressure and high frequency vibration, greatly improve the sealing performance of the joint assembly, and significantly reduce the risk of hydraulic oil leakage. The sealing ring is made of wear-resistant material, and the special design of the opening of the external fixed tube makes it more convenient to connect the joint assembly to the hose body. The nut is tightened more tightly after tightening.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] like Figures 1-4 As shown, the high-sealing hydraulic hose connector of this embodiment includes a hose body 1. A connector assembly 2 is movably connected to the side surface of the hose body 1. The connector assembly 2 includes a connecting support pipe 3, an outer fixing pipe 4, and a nut 41. The connecting support pipe 3 and the outer fixing pipe 4 are fixedly connected. An installation groove 6 is provided between the connecting support pipe 3 and the outer fixing pipe 4. The connecting support pipe 3 is used to support one end of the hose body 1 to prevent the material of the connecting part of the hose body 1 from being too soft, which could lead to leakage after connection. The installation groove 6 is used to insert one end of the hose body 1.

[0025] When installing the hose body 1 and the connector assembly 2, the sealing ring 9 is placed inside the first sealing ring 8 and then placed outside the hose body 1. At this time, the connecting support tube 3 is inserted into the hose body 1 to support the hose body 1. After adjusting the position of the first sealing ring 8, the nut 41 is tightened. At this time, the opening 7 of the outer fixing tube 4 contracts, so that the outer fixing tube 4 squeezes the first sealing ring 8 to make the connection tight and improve the sealing performance. This allows the device to effectively cope with the complex working conditions of high pressure and high frequency vibration, avoid oil leakage during use, and connect the connector assembly 2 and the hose body 1 together.

[0026] A first sealing ring 8 is movably connected to the side surface of the hose body 1, and a limit ring 5 is fixedly connected to the side surface of the outer fixing tube 4. The limit ring 5 can prevent the nut 41 from slipping off. The inner side wall of the outer fixing tube 4 is in contact with the first sealing ring 8. A sealing ring 9 is provided on the inner side wall of the first sealing ring 8. The inner side wall of the hose body 1 is in contact with the connecting support tube 3. The inner side wall of the sealing ring 9 is in contact with the hose body 1. An opening 7 is provided on the side surface of the outer fixing tube 4. A threaded groove is provided on the side surface of the outer fixing tube 4.

[0027] The multi-seal structure design of the first sealing ring 8 and the sealing ring 9 can effectively cope with complex working conditions such as high pressure and high frequency vibration, greatly improve the sealing performance of the joint assembly 2, and significantly reduce the risk of hydraulic oil leakage.

[0028] Limiting blocks 10 are arrayed on the side surface of the hose body 1. The limiting blocks 10 are used to limit the installation position of the first sealing ring 8 and prevent the nut 41 from slipping when it is turned. The first sealing ring 8 is made of high-performance rubber material and has a special trapezoidal cross-section. The sealing ring 9 is made of polytetrafluoroethylene material. The first sealing ring 8 has a special trapezoidal cross-section, which makes it produce a good sealing effect when it is squeezed when the nut 41 is turned. The sealing ring 9 is made of polytetrafluoroethylene material, which helps the first sealing ring 8 to further improve the sealing performance and enhance the wear resistance of the sealing ring 9.

[0029] The working principle of this utility model is as follows: When connecting the hose body 1 to other pipes, firstly, install the connector assembly 2 on the hose body 1, then put the sealing ring 9 inside the first sealing ring 8 and then put it on the outside of the hose body 1. At this time, insert the connecting support tube 3 into the hose body 1 to support the hose body 1. After adjusting the position of the first sealing ring 8, tighten the nut 41. At this time, the opening 7 of the outer fixing tube 4 contracts, so that the outer fixing tube 4 squeezes the first sealing ring 8, thereby connecting the connector assembly 2 and the hose body 1 together.

[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
