Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-5, An embodiment provided by the utility model: A hydraulic joint assembly for preventing side explosion, including a docking platform 1, a docking pipe 2 and an insertion pipe 3.

A connection cap 6 is arranged on the outer sides of the docking pipe 2 and the insertion pipe 3. A tail pipe 7 is fixed to the left side of the docking platform 1. An explosion-proof pressure relief component is arranged at the bottom end of the tail pipe 7. The explosion-proof pressure relief component includes a pressure relief platform 8, a connection groove 9, a pressure relief pipe 10, an installation groove 11, a rubber ring 12, an auxiliary platform 13, a partition plate 14, a pressure relief hole 15, a ball core 16 and a first spring 17. The pressure relief platform 8 is fixed to the bottom end of the tail pipe 7. The connection groove 9 is arranged at the bottom end of the pressure relief platform 8. The pressure relief pipe 10 is arranged inside the connection groove 9. The top end of the pressure relief pipe 10 extends into the interior of the pressure relief platform 8. Internal threads are arranged inside the connection groove 9. External threads are arranged on the surface of the pressure relief pipe 10. The installation groove 11 is arranged at the top end of the outer side wall of the pressure relief pipe 10. The rubber ring 12 is installed inside the installation groove 11. The auxiliary platform 13 is fixed to the top end of the pressure relief pipe 10. The partition plate 14 is fixed to the top end inside the pressure relief platform 8. The pressure relief hole 15 is arranged at the center position of the top end of the partition plate 14. The ball core 16 is arranged inside the pressure relief hole 15. The first spring 17 is arranged at the bottom end of the ball core 16. The bottom end of the first spring 17 extends into the interior of the auxiliary platform 13;

[0025] Specifically, as Figure 1 , Figure 2 and Figure 3 shown, during use, with the assistance of the first spring 17, the ball core 16 is stuck at the pressure relief hole 15 on the surface of the partition plate 14 for sealing. If the pressure inside the tail pipe 7 is greater than the thrust exerted by the first spring 17, the ball core 16 moves downward. When the pressure relief hole 15 is opened, the medium inside the tail pipe 7 can flow along the pressure relief platform 8 and the pressure relief pipe 10 to the outside for pressure relief. When the pressure relief pipe 10 is manually rotated upward, the first spring 17 can be compressed to assist in adjusting the pressure exerted by the first spring 17 on the ball core 16;

[0026] A fixing platform 18 is fixed to the outer side wall of the connection cap 6. A plurality of fixing platforms 18 are fixed to the outer side wall of the connection cap 6. The plurality of fixing platforms 18 are symmetrically distributed. A fixing hole 19 is arranged inside the fixing platform 18. A fixing bolt 20 is arranged inside the fixing hole 19;

[0027] Specifically, as Figure 1 , Figure 2 and Figure 4As shown in the figure, during use, as the connecting cap 6 is docked with the docking pipe 2 through threads, after the position of the auxiliary insertion pipe 3 is fixed, multiple fixing bolts 20 on the outer side of the connecting cap 6 can be rotated. The fixing bolts 20 abut against the surface of the docking pipe 2, which can assist in increasing the friction between the connecting cap 6 and the docking pipe 2, preventing the connecting cap 6 from reversing and causing the connection between the insertion pipe 3 and the docking pipe 2 to become loose.

[0028] A liquid inlet groove 21 is provided on the left side of the insertion pipe 3. A partition table 22 is fixed inside the docking platform 1. A through groove 23 is penetrated through the left side of the partition table 22. A sliding groove 24 is penetrated through the center position on the left side of the partition table 22. A linkage rod 25 is arranged inside the sliding groove 24. A cover plate 26 is fixed on the left side of the linkage rod 25. A second spring 27 is fixed on the right side of the cover plate 26. A reset groove 28 is provided on the left side of the partition table 22. The right side of the second spring 27 is fixedly connected with the inside of the reset groove 28.

[0029] Specifically, as Figure 1 and Figure 5 shown in the figure, during use, as the insertion pipe 3 is inserted into the inside of the docking pipe 2 for docking, the front end of the insertion pipe 3 can push the linkage rod 25 and the cover plate 26 to move. After the cover plate 26 is separated from the partition table 22, the through groove 23 on the surface of the partition table 22 is opened. At this time, the medium inside the tail pipe 7 can enter the insertion pipe 3 along the through groove 23 and the liquid inlet groove 21.

[0030] Working principle: During use, first, the sealing ring 5 is sleeved on the outer side of the insertion pipe 3 and contacts the limit platform 4. Then, the insertion pipe 3 is inserted into the inside of the docking pipe 2. As the docking pipe 2 contacts and presses the limit platform 4 on the outer side of the insertion pipe 3, the connecting cap 6 can be slid. Through the threaded fit between the connecting cap 6 and the docking pipe 2, they are connected, and the position of the insertion pipe 3 is fixed by means of the connecting cap 6. After the connecting cap 6 is connected, the multiple fixing bolts 20 on the outer side of the connecting cap 6 are tightened. The fixing bolts 20 abut against the surface of the docking pipe 2, which can assist in increasing the friction between the connecting cap 6 and the docking pipe 2, avoiding the connecting cap 6 from reversing and causing the connection to become loose. When the insertion pipe 3 is inserted into the inside of the docking pipe 2, the front end of the insertion pipe 3 can push the linkage rod 25 and the cover plate 26. After the cover plate 26 is separated from the partition table 22, the through groove 23 on the surface of the partition table 22 is opened. At this time, the medium inside the tail pipe 7 can enter the insertion pipe 3 along the through groove 23 and the liquid inlet groove 21. The pressure relief platform 8 is communicated with the inside of the tail pipe 7. If the pressure inside the tail pipe 7 is too high, when the ball core 16 is pushed downward to separate from the pressure relief hole 15, the medium inside the tail pipe 7 can enter the pressure relief platform 8 along the pressure relief hole 15, and then is drained to the outside through the pressure relief pipe 10 to assist in the pressure relief process. When the pressure relief pipe 10 is manually rotated upward, the first spring 17 can be compressed to assist in adjusting the pressure applied by the first spring 17 on the ball core 16 to adapt to different pressure use requirements.
