[0022] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] Embodiment 1, as Figures 1 - 5As shown in the figure, the utility model provides a hydraulic hose three-way joint with a protection structure, including a joint body 1. A first sheath 2 and a second sheath 3 are sleeved on the outer wall of the joint body 1. Two first connecting plates 4 are fixedly installed on the outer wall of the first sheath 2, and two second connecting plates 5 are fixedly installed on the outer wall of the second sheath 3. Plug blocks 6 are fixedly installed at the bottoms of the two first connecting plates 4. A clamping groove 8 is formed on the outer wall of the plug block 6. Slots 7 are formed at the tops of the two second connecting plates 5. A limiting groove 9 is formed on the inner wall of the slot 7. A spring 10 is fixedly installed on the inner wall of the limiting groove 9. A clamping block 11 is fixedly installed at one end of the spring 10. A through hole 15 is formed through the inner wall of the limiting groove 9. A moving plate 12 is fixedly installed at the end of the clamping block 11 close to the through hole 15. The moving plate 12 is slidably connected with the through hole 15. A pulling plate 13 is fixedly installed at the end of the moving plate 12 away from the clamping block 11.

[0025] The effect achieved by the entire embodiment 1 is that during disassembly, the staff pulls the pulling plate 13. The pulling plate 13 drives the moving plate 12 to move, and then drives the clamping block 11 to leave the clamping groove 8. At this time, the staff can pull out the plug block 6 from the slot 7. At this time, the first sheath 2 and the second sheath 3 can be disassembled from the joint body 1, improving the installation and disassembly efficiency and facilitating replacement.

[0026] Embodiment 2, as Figures 1 - 5 shown, further, fixing grooves 14 are formed on the inner walls of the two through holes 15, and threaded holes 16 are formed through the inner walls of the fixing grooves 14.

[0027] Further, threaded rods 17 are threadedly connected inside the two threaded holes 16. A pressing block 18 is fixedly installed at one end of the threaded rod 17. A handle 19 is fixedly installed at the end of the threaded rod 17 away from the pressing block 18.

[0028] Further, a plurality of uniformly distributed arched supports 20 are fixedly installed on the sides of the first sheath 2 and the second sheath 3 close to the joint body 1. An elastic steel ring 21 is fixedly installed on the outer wall of the arched support 20. An energy-absorbing rubber block 22 is fixedly installed on the inner wall of the elastic steel ring 21. A connecting block 23 is fixedly installed on the outer wall of the elastic steel ring 21. The sides of the plurality of connecting blocks 23 away from the elastic steel ring 21 are respectively fixedly connected with the inner walls of the first sheath 2 and the second sheath 3.

[0029] Further, guide rods 24 are fixedly installed on both sides of the plurality of connecting blocks 23. Chute grooves 25 are formed on both sides of the plurality of arched supports 20. One ends of the two guide rods 24 are respectively slidably connected with the two chute grooves 25.

[0030] Further, the outer walls of the two clamping blocks 11 are respectively fitted with the inner walls of the two clamping grooves 8. The outer walls of the two plug blocks 6 are fitted with the inner walls of the two slots 7. When the clamping block 11 enters the clamping groove 8, it can prevent the plug block 6 from shaking and affecting the fixation.

[0031] Furthermore, the inner walls of the two through ports 15 are respectively in contact with the outer walls of the two moving plates 12 to prevent the clamping blocks 11 from shaking in the limiting grooves 9.

[0032] The overall effect achieved by the entire Embodiment 2 is that at the end of the installation, the staff rotates the handle 19, the threaded rod 17 rotates, causing the threaded rod 17 to move along the threaded hole 16, thereby driving the abutting block 18 to move. The abutting block 18 contacts the moving plate 12 to fix the moving plate 12 and prevent the external force from accidentally touching the pull plate 13, which may cause the clamping block 11 to leave the clamping groove 8, resulting in unstable fixation.

[0033] Working principle: During installation, the staff inserts the insertion block 6 into the insertion slot 7. When the insertion block 6 contacts the inclined surface of the clamping block 11, the insertion block 6 pushes the clamping block 11 to move, causing the clamping block 11 to enter the limiting groove 9, and the spring 10 is compressed. When the clamping groove 8 moves beside the clamping block 11, the clamping block 11 enters the clamping groove 8 under the elastic force of the spring 10 to fix the insertion block 6. At this time, the first sheath 2 and the second sheath 3 are fixed on the outer wall of the joint body 1. At the end of the installation, the staff rotates the handle 19, the threaded rod 17 rotates, causing the threaded rod 17 to move along the threaded hole 16, thereby driving the abutting block 18 to move. The abutting block 18 contacts the moving plate 12 to fix the moving plate 12 and prevent the external force from accidentally touching the pull plate 13, which may cause the clamping block 11 to leave the clamping groove 8, resulting in unstable fixation. During disassembly, the staff pulls the pull plate 13, the pull plate 13 drives the moving plate 12 to move, thereby driving the clamping block 11 to leave the clamping groove 8. At this time, the staff can pull out the insertion block 6 from the insertion slot 7, and then the first sheath 2 and the second sheath 3 can be disassembled from the joint body 1, improving the installation and disassembly efficiency and facilitating replacement. When an object collides with the joint body 1, through the settings of the first sheath 2 and the second sheath 3, it can prevent the object from directly hitting the joint body 1, playing a role of partition protection. Moreover, when the object hits the first sheath 2 and the second sheath 3, it will drive the connecting block 23 to move. The movement of the connecting block 23 will squeeze the elastic steel ring 21 to deform. After the elastic steel ring 21 deforms, it will compress the energy-absorbing rubber block 22 to absorb the impact force. Then the remaining impact force is transmitted to the arched support 20. Through the setting of the arched support 20 and using the good force-averaging effect of the arch, the received impact force can be evenly distributed, avoiding the impact force concentrating on one point and maintaining the force balance of the joint body 1.

[0034] The above is only a preferred embodiment of the present invention, and it does not limit the present invention in other forms. Any person skilled in the relevant art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
