[0002] In many fields such as industrial production and engineering construction, hydraulic systems are key devices for transmitting power. Their stable operation is directly related to the efficiency and safety of the entire equipment and even the production process. As the core component connecting hoses and equipment in the hydraulic system, the performance of hydraulic hose joints is particularly important.

[0003] The currently used positioning anti-detachment hydraulic hose connector is mainly composed of positioning tube, connector, socket, installation tube and other components, and is suitable for engineering machinery, industrial manufacturing, agricultural machinery and mining machinery and other scenarios.

[0004] The currently used positioning anti-dislodgement hydraulic hose connector effectively achieves the matching between different hoses. However, traditional hydraulic hose connectors often face the problem of dislodgement due to factors such as vibration, pressure fluctuations, and improper installation during long-term use. At the same time, the hose itself cannot control the flow of fluid. Therefore, a positioning anti-dislodgement hydraulic hose connector is proposed to solve the above problems. Utility Model Content

A positioning groove is opened on the front side of the sealing ball. A rotating block is abutted against the front side of the sealing ball. The bottom of the rotating block abuts against the inside of the positioning groove. A bearing is fixedly connected to the top of the rotating block. A valve stem is rotatably connected inside the bearing. A handwheel is fixedly connected to the top of the valve stem.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-5This utility model provides an embodiment of a positioning and anti-detachment hydraulic hose connector, including a female main pipe 1, with a positioning tube 2 fixedly connected to the outside of the female main pipe 1, providing precise guidance and installation space for the subsequent insertion and positioning of the male main pipe 19, ensuring that the male main pipe 19 can accurately mate with the female main pipe 1. An installation tube 6 is fixedly connected to the outside of the female main pipe 1, and a guide tube 7 is fixedly connected inside the installation tube 6. A limiting tube 3 is fixedly connected to the outside of the positioning tube 2, which restricts the sliding range of the moving tube 5 on the positioning tube 2, preventing the moving tube 5 from sliding excessively and detaching from the positioning tube 2. A moving tube 5 is slidably connected to the outside of the positioning tube 2, and the moving tube 5 is sleeved on the outside of the positioning tube 2 and can slide back and forth. When the male main pipe 19 is inserted into the positioning tube 2, sliding the moving tube 5 can push the internal ball bearing 13 to lock in place. The male main pipe 19 is fixed in the groove 14. Conversely, the sliding moving pipe 5 can also release the fixation of the male main pipe 19. The top of the limiting pipe 3 is fixedly connected to the return spring 4, and the bottom of the moving pipe 5 is fixedly connected to the return spring 4. The two ends of the return spring 4 are respectively connected to the limiting pipe 3 and the moving pipe 5. When the moving pipe 5 is slidable, the return spring 4 will generate elastic force due to deformation. When the external force disappears, this elastic force can drive the moving pipe 5 to automatically return to its original position. The positioning pipe 2 is slidably connected to the ball 13. The positioning pipe 2 has a sliding groove 21. The ball 13 is slidably connected in the sliding groove 21. The positioning pipe 2 is slidably connected to the male main pipe 19. The male main pipe 19 has a limiting groove 14 on the outside. The ball 13 abuts in the limiting groove 14. The guide pipe 7 is equipped with a valve assembly.

[0034] Reference Figure 1 and Figure 5 The valve assembly includes a sealing valve seat 10, which is externally fixedly connected to the inside of the guide tube 7. The top of the sealing valve seat 10 abuts against a sealing ball 8. A positioning groove 22 is provided on the front side of the sealing ball 8. The positioning groove 22 is a groove on the front of the sealing ball 8. Its shape matches the bottom of the rotating block 23, allowing the rotating block 23 to be stably locked inside. When the rotating block 23 rotates, it can drive the sealing ball 8 to rotate together, realizing the opening and closing action of the sealing ball 8. The front side of the sealing ball 8 abuts against the rotating block 23, and the bottom of the rotating block 23 abuts against the inside of the positioning groove 22. A bearing 11 is fixedly connected to the top of the rotating block 23. The bearing 11 can reduce the friction between the rotating block 23 and the valve stem 9, making the rotating block 23 rotate more smoothly with the valve stem 9, and also ensuring the stable rotation direction of the rotating block 23. The valve stem 9 is rotatably connected inside the bearing 11, and a handwheel 12 is fixedly connected to the top of the valve stem 9.

[0035] Reference Figure 2 and Figure 3Both the female main pipe 1 and the male main pipe 19 have fixed blocks 16 inside. The fixed blocks 16 provide installation and support points for the second return spring 18. Both the female main pipe 1 and the male main pipe 19 have sealing posts 20 inside. The top of the sealing posts 20 is fixedly connected to a cone 17. The top of the fixed blocks 16 is connected to the second return spring 18. The bottom of the sealing posts 20 is abutted against the top of the second return spring 18. The two cones 17 abut against each other and compress the second return spring 18, causing the sealing posts 20 to disengage from the sealing position and enabling fluid conduction. The rear side of the male main pipe 19 is fixedly connected to an installation pipe 6 of the same size. The installation pipe 6 is fixedly connected to a guide pipe 7 of the same size. The guide pipe 7 is equipped with a valve assembly identical to that of the female main pipe 1. The outer side of the male main pipe 19 is fixedly connected to a sealing ring 15, which is made of nitrile rubber.

[0036] Working principle: First, connect the female main pipe 1 and the male main pipe 19 to the two hoses to be connected. Then, insert the male main pipe 19 into the positioning tube 2 of the female main pipe 1. At the same time, drag the moving tube 5 to compress the return spring 4 until the ball 13 abuts in the limiting groove 14. Then release the moving tube 5. The return spring 4 will rebound and move the moving tube 5 back to the initial position to fix the ball 13. At this time, the two cones 17 abut against each other and compress the return spring 18, so that the sealing column 20 is disengaged from the sealing position and fluid conduction is achieved. The handwheels 12 of the female main pipe 1 and the male main pipe 19 can adjust the rotation of their sealing balls 8 to achieve a complete seal.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
