Description

Technical Field

[0001] This utility model relates to the field of hydraulic connector technology, specifically an adjustable hydraulic connector. Background Technology

[0002] Hydraulic pipes play a crucial role in hydraulic systems. They are the pipes used to transmit hydraulic oil. Common types include steel pipes, such as seamless steel pipes, which have advantages such as high strength, high pressure resistance, and strong corrosion resistance. Hydraulic pipes require connectors during use to connect with other hydraulic components (such as hydraulic cylinders, hydraulic pumps, valves, etc.) to ensure the normal operation of the hydraulic system.

[0003] Common hydraulic connectors mainly consist of a connector body, a nut, and a connecting pipe. One end of the connector body is connected to the oil port of the hydraulic component, and the other end is fixed to the hydraulic pipe by welding. The structure itself does not have a flow regulation mechanism. The welding method fixes the inner diameter of the pipe, and there is no device to change the flow cross-sectional area of ​​the fluid channel, so the flow rate cannot be adjusted. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable hydraulic connector to solve the problem mentioned in the background art that the common hydraulic connectors mainly consist of a connector body, a nut, and a connecting pipe. One end of the connector body is connected to the oil port of the hydraulic component, and the other end is fixed to the hydraulic pipe by welding. Its structure itself does not have a flow adjustment mechanism. The welding fixation method makes the inner diameter of the pipe fixed, and the fluid channel does not have a device to change the flow cross-sectional area, so the flow rate cannot be adjusted.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable hydraulic connector, including a first connecting part and a second connecting part, a connecting component fixedly connected between the first connecting part and the second connecting part, a receiving tube fixedly connected to one end of the first connecting part near the second connecting part, a sealing component disposed inside the receiving tube, a insertion tube fixedly connected to one end of the second connecting part near the first connecting part, a transmission component drivingly connected to the middle of the insertion tube body, a positioning component movably connected to one end of the insertion tube body away from the receiving tube, a sealing gasket movably connected inside the receiving tube, and the insertion tube inserted into the receiving tube with its end in contact with the sealing gasket. This hydraulic connector allows adjustment of the size of the opening in the pipeline by adjusting the position of the moving plate, thereby controlling the flow rate inside the pipeline. By connecting the pipeline with other components through the hydraulic connector, flexible control of the flow rate of different branches or the entire system can be achieved, optimizing the performance of the hydraulic system and enabling it to better adapt to various complex work tasks and changing operating conditions. This helps to achieve precise, stable, and flexible flow control, thereby improving the performance and reliability of the entire hydraulic system.

[0006] Preferably, the connecting assembly includes four supporting arc plates and four threaded connecting plates. The four supporting arc plates are fixedly connected at equal angles to the edge of the first connecting part near the edge of the second connecting part. The four threaded connecting plates are fixedly connected at equal angles to the edge of the second connecting part near the edge of the first connecting part. Limiting arc plates are fixedly connected to the outer sides of the ends of the four supporting arc plates away from the first connecting part. The four supporting arc plates and the four threaded connecting plates are staggered. The outer sides of the four threaded connecting plates are threaded and connected with connecting nuts, making the connection between the first connecting part and the second connecting part more stable.

[0007] Preferably, the sealing assembly includes four fixed posts, which are symmetrically fixedly installed inside the receiving tube. Each of the four fixed posts has a stop block fixedly connected to its end. Each of the four fixed posts has a return spring movably sleeved in the middle. Each of the four fixed posts has a movable plate movably sleeved on its outer side. One side of the stop block is in contact with one end of the return spring. The movable plate can automatically reset under the push of the return spring when it is not under force, thus achieving a seal.

[0008] Preferably, the transmission assembly includes a mounting ring, which is fixedly installed in the middle of the insertion pipe body. A threaded push rod is threadedly connected to the middle of the mounting ring. One end of the threaded push rod is in contact with the middle of the stop block, and the other end of the stop block is fixedly connected to a transmission gear ring. The rotation of the threaded push rod engages with the mounting ring, thereby changing the position of the threaded push rod on the mounting ring, which in turn pushes the moving plate to move different distances, thus changing the gap between the moving plate and the receiving pipe, making it easier to adjust the fluid throughput per unit time.

[0009] Preferably, the positioning component includes a positioning ring, which is movably engaged inside the insertion tube. The positioning ring has multiple through holes at equal angles on its side center. Three positioning rods are fixedly connected at equal angles on the side of the positioning ring near the transmission gear ring. The positioning rods engage with the transmission gear ring, and the positioning rods position the transmission gear ring, restricting its rotation, so that the threaded push rod cannot rotate or move.

[0010] Preferably, the end of the insertion tube away from the insertion tube has a threaded groove inside, and a locking ring seat is threadedly connected inside the threaded groove. The locking ring seat has a polygonal through groove inside, and the positioning ring is squeezed and fixed by the locking ring seat, thereby limiting and fixing the transmission gear ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This hydraulic connector, through its designed fixed column, return spring, stop block, moving plate, threaded push rod, positioning ring, through hole, transmission gear ring, locking ring seat, positioning rod, threaded groove, mounting ring, and connecting nut, works by rotating the transmission gear ring to engage the threaded push rod and mounting ring, causing the threaded push rod to push or pull the moving plate, thereby changing the size of the gap between the moving plate and the receiving tube, thus controlling the flow rate inside the receiving tube. At the same time, the positioning ring, positioning rod, and mounting ring limit the transmission gear ring, ensuring that the size of the gap between the adjusted moving plate and the receiving tube is fixed, guaranteeing stable flow control.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Please see Figure 1-4This utility model provides an adjustable hydraulic connector, including a first connecting part 1 and a second connecting part 4. A connecting component is fixedly connected between the first connecting part 1 and the second connecting part 4. A receiving tube 6 is fixedly connected to one end of the first connecting part 1 near the second connecting part 4. A sealing component is provided inside the receiving tube 6. A insertion tube 7 is fixedly connected to one end of the second connecting part 4 near the first connecting part 1. A transmission component is drivenly connected to the middle of the tube body of the insertion tube 7. A positioning component is movably connected to one end of the tube body of the insertion tube 7 away from the receiving tube 6. A sealing gasket 8 is movably connected inside the receiving tube 6. The insertion tube 7 is inserted into the receiving tube 6 and the end of the insertion tube 7 contacts and connects with the sealing gasket 8. The design of the sealing gasket 8 makes the sealing effect better after the insertion tube 7 and the receiving tube 6 are connected, preventing fluid leakage inside the pipeline.

[0020] Furthermore, the connecting assembly includes four supporting arc plates 2 and four threaded connecting plates 5. The four supporting arc plates 2 are fixedly connected at equal angles to the edge of the first connecting part 1 near the edge of the second connecting part 4. The four threaded connecting plates 5 are fixedly connected at equal angles to the edge of the second connecting part 4 near the edge of the first connecting part 1. Limiting arc plates 3 are fixedly connected to the outer sides of the ends of the four supporting arc plates 2 away from the first connecting part 1. The four supporting arc plates 2 and the four threaded connecting plates 5 are staggered. The outer sides of the four threaded connecting plates 5 are threaded, and connecting nuts 21 are threadedly connected to the outer sides of the threaded connecting plates 5. When the first connecting part 1 and the second connecting part 4 are connected, the insertion tube 7 is inserted into the receiving tube 6 so that the end of the insertion tube 7 contacts and connects with the sealing gasket 8. Then, the connecting nut 21 is rotated so that the connecting nut 21 and the threaded connecting plate 5 are screwed together until one side of the connecting nut 21 presses against the limiting arc plate 3, so that the first connecting part 1 and the second connecting part 4 are stably connected.

[0021] Furthermore, the sealing assembly includes four fixed posts 9, which are symmetrically fixed inside the receiving tube 6. Each of the four fixed posts 9 has a stop block 11 fixedly connected to its end. The stop block 11 is designed to prevent the return spring 10 from falling off the fixed post 9. The return spring 10 is movably sleeved in the middle of each of the four fixed posts 9. A movable plate 12 is movably sleeved on the outside of the four fixed posts 9. One side of the stop block 11 is in contact with one end of the return spring 10. When the movable plate 12 moves, it pushes the return spring 10 to compress. The movable plate 12 moves closer to the stop block 11. At this time, the gap between the movable plate 12 and the end of the receiving tube 6 is exposed, and fluid can pass through.

[0022] Furthermore, the transmission assembly includes a mounting ring 20, which is fixedly installed in the middle of the insertion tube 7. A threaded push rod 13 is threadedly connected to the middle of the mounting ring 20. One end of the threaded push rod 13 is in contact with the middle of the stop block 11, and the other end of the stop block 11 is fixedly connected to a transmission gear ring 16. Multiple locking teeth are fixedly connected to the transmission gear ring 16, and each locking tooth corresponds to a fixed rotation angle. Different rotation angles directly affect the receiving tube 6 of the moving plate 12. An internal hexagonal socket is fixedly connected to the end of the transmission gear ring 16 to facilitate the adjustment of the position of the threaded push rod 13 before the connector is connected. When the transmission gear ring 16 rotates, it drives the threaded push rod 13 to rotate. The threaded push rod 13 rotates and engages with the mounting ring 20, changing the relative position of the threaded push rod 13 and the mounting ring 20. The threaded push rod 13 pushes the moving plate 12 to move.

[0023] Furthermore, the positioning component includes a positioning ring 14, which is movably engaged inside the insertion tube 7. Multiple through holes 15 are equally spaced on the middle of the side of the positioning ring 14. Three positioning rods 18 are fixedly connected at equal angles on the side of the positioning ring 14 near the transmission gear ring 16. The positioning rods 18 are engaged with the transmission gear ring 16. When adjusting the transmission gear ring 16, a tool is used to rotate the transmission gear ring 16, causing it to rotate and drive the threaded push rod 13 to rotate. After the threaded push rod 13 is properly positioned, the positioning ring 14 is inserted into the insertion tube 7, and simultaneously, the positioning rods 18 on one side of the positioning ring 14 engage with the transmission gear ring 16.

[0024] Furthermore, a threaded groove 19 is provided inside the end of the insertion tube 7 away from the insertion tube 7. A locking ring seat 17 is threadedly connected inside the threaded groove 19. A polygonal through groove is provided inside the locking ring seat 17. After the positioning rod 18 on one side of the positioning ring 14 and the transmission gear ring 16 are engaged, the locking ring seat 17 is rotated and screwed into the threaded groove 19 to squeeze and position the positioning ring 14, so that the position of the transmission gear ring 16 is fixed.

[0025] When this application embodiment is used:

[0026] When using this connector, first connect the first connecting part 1 and the second connecting part 4, insert the insertion tube 7 into the receiving tube 6 so that the end of the insertion tube 7 contacts and connects with the sealing gasket 8, then rotate the connecting nut 21 so that the connecting nut 21 and the threaded connecting plate 5 are engaged until one side of the connecting nut 21 presses against the limiting arc plate 3, so that the first connecting part 1 and the second connecting part 4 are stably connected. Use a tool to rotate the transmission gear ring 16 so that the transmission gear ring 16 rotates and drives the threaded push rod 13 to rotate. The threaded push rod 13 rotates and engages with the mounting ring 20, and the relative position of the threaded push rod 13 and the mounting ring 20 changes. The threaded push rod 13 pushes the moving plate 12 to move. After the position of the threaded push rod 13 is adjusted, insert the positioning ring 14 into the insertion tube 7. At the same time, the positioning rod 18 on one side of the positioning ring 14 engages with the transmission gear ring 16.
