[0022] Please refer to Figures 1 to 5 , where Figure 1 is a schematic structural diagram of a preferred embodiment of a quick-disassembly hydraulic joint provided by the present utility model; Figure 2 is Figure 1 a schematic exploded view of the parts of the whole shown; Figure 3 is Figure 2 a schematic left view sectional structure diagram of the wire hose shown; Figure 4 is Figure 2 a schematic structural diagram of the extrusion ring shown; Figure 5 is Figure 2 a schematic rear view structure diagram of the fixed cylinder shown. A quick-disassembly hydraulic joint includes: a socket 1;

[0023] A sleeve joint 2 is inserted at the front end of the socket 1. A plug 3 is fixedly connected to the front end of the socket 1. A first groove 4 is provided on the circumferential side of the plug 3. A wire hose 5 is fixedly connected to the front end of the sleeve joint 2. A rubber sealing ring 6 is fixedly connected to the inner wall of the wire hose 5. The rubber sealing ring 6 is matched with the first groove 4. A first rotating groove 7 is provided on the circumferential side of the sleeve joint 2. A threaded cylinder 8 is rotatably connected to the rear end of the sleeve joint 2. The front end of the threaded cylinder 8 is rotatably connected inside the first rotating groove 7, and the threaded cylinder 8 is matched with the first thread 9. A raised ring 10 is fixedly connected to the circumferential side of the wire hose 5. A fixed cylinder 11 is fixedly connected to the front end of the wire hose 5. A spring 12 is fixedly connected to the rear end of the fixed cylinder 11. An extrusion ring 13 is provided at the rear end of the spring 12. The elastic force of the spring 12 on the extrusion ring 13 can cause the extrusion ring 13 to extrude the raised ring 10, so that the rubber sealing ring 6 is tightly stuck to the inner wall of the first groove 4, improving the sealing performance.

[0024] An annular groove 14 is provided at the rear end of the fixed cylinder 11. The front end of the spring 12 is fixedly connected inside the annular groove 14. The provision of the annular groove 14 is conducive to the contraction of the spring 12, thus facilitating the approach of the extrusion ring 13 to the fixed cylinder 11.

[0025] A second rotating groove 15 is provided at the front end of the extrusion ring 13. A connecting ring 16 is rotatably connected inside the second rotating groove 15. The connecting ring 16 is fixedly connected to the rear end of the spring 12. The provision of the connecting ring 16 is conducive to the rotation of the extrusion ring 13.

[0026] A clamping block 17 is fixedly connected to the front end of the extrusion ring 13, and two groups of clamping blocks 17 are provided.

[0027] Two groups of slots 18 are opened at the rear end of the fixed cylinder 11, and the clamping block 17 is matched with the slot 18.

[0028] A clamping groove 19 is opened on the left side of the inner wall of the slot 18, and the clamping groove 19 is matched with the clamping block 17. The extrusion ring 13 can be limited by the cooperation of the clamping block 17 and the clamping groove 19.

[0029] The working principle of a quick-disassembly and quick-assembly hydraulic joint provided by the present utility model is as follows:

[0030] First step: When in use, push the extrusion ring 13 towards the fixed cylinder 11 to make the spring 12 contract, then insert the plug 3 into the socket joint 2 and the steel wire hose 5 until the rubber sealing ring 6 is stuck into the first groove 4, and then rotate the threaded cylinder 8 so that the threaded cylinder 8 is sleeved on the circumferential side of the first thread 9. When the threaded cylinder 8 is sleeved on the circumferential side of the first thread 9, release the extrusion ring 13. At this time, by squeezing the protruding ring 10 through the extrusion ring 13, the rubber sealing ring 6 can be tightly clamped with the first groove 4.

[0031] Second step: Before installation, first push the extrusion ring 13 towards the fixed cylinder 11 until the clamping block 17 is inserted into the slot 18, and then rotate the extrusion ring 13 so that the protruding part of the clamping block 17 is stuck into the clamping groove 19. At this time, the extrusion ring 13 can be limited. When the plug connector 1 and the socket joint 2 are connected well and the threaded cylinder 8 is fixed, rotate the extrusion ring 13 in the reverse direction so that the clamping block 17 is completely inside the slot 18. At this time, through the elastic force of the spring 12, the extrusion ring 13 can squeeze the protruding ring 10.

[0032] Compared with the related technology, a quick-disassembly and quick-assembly hydraulic joint provided by the present utility model has the following beneficial effects:

[0033] Push the extrusion ring 13 towards the fixed cylinder 11 to contract the spring 12, and then insert the plug 3 into the inside of the socket joint 2 and the steel wire hose 5 until the rubber sealing ring 6 snaps into the first groove 4. Then rotate the threaded cylinder 8 so that the threaded cylinder 8 is sleeved on the circumferential side of the first thread 9. When the threaded cylinder 8 is sleeved on the circumferential side of the first thread 9, release the extrusion ring 13. At this time, by squeezing the convex ring 10 through the extrusion ring 13, the rubber sealing ring 6 can be tightly clamped with the first groove 4. With this structure, the joint can be quickly disassembled and assembled without the aid of tools, which is very convenient to use. Before installation, first push the extrusion ring 13 towards the fixed cylinder 11 until the locking block 17 is inserted into the slot 18, and then rotate the extrusion ring 13 so that the protruding part of the locking block 17 snaps into the clamping groove 19. At this time, the extrusion ring 13 can be limited. When the plug joint 1 and the socket joint 2 are connected and the threaded cylinder 8 is fixed, rotate the extrusion ring 13 in the reverse direction so that the locking block 17 is completely inside the slot 18. At this time, through the elastic force of the spring 12, the extrusion ring 13 can squeeze the convex ring 10. With this structure, the extrusion ring 13 can be limited, making it more convenient to disassemble and assemble the joint.

[0034] Finally, it should be pointed out that the above embodiments are only relatively representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and there can be many variations.
