A hydraulic joint assembly includes: a joint 1, and a connection assembly 2 is arranged on the left side of the joint 1;

[0023] The connection assembly 2 includes a docking part 21 arranged on the left side of the joint 1. An equipment connection pipe 22 is threadedly connected to the outside of the docking part 21. Slots 23 are opened at the top and bottom of the docking part 21, and limit posts 24 are slidably arranged up and down on the inner sides of the two slots 23.

[0024] Limit springs 25 are arranged on the inner sides of the two slots 23 and respectively at the opposite ends of the two limit posts 24. Limit holes 26 are opened at the top and bottom of the equipment connection pipe 22, and when the two limit posts 24 extend out, they are respectively located inside the two limit holes 26.

[0025] When the docking part 21 is screwed into the equipment connection pipe 22, the limit posts 24 will retract inside the slots 23 when entering. When the top of the limit post 24 is at the limit hole 26, under the action of the limit spring 25, the limit post 24 pops up. At this time, the docking part 21 is also connected to the equipment connection pipe 22. Through the arrangement of the upper and lower two limit posts 24, the connection between the docking part 21 and the equipment connection pipe 22 after connection is strengthened, improving the sealing and compressive resistance effects.

[0026] A fitting ring 27 is arranged on the left side of the joint 1, and a sealing ring 28 is arranged on the outside of the fitting ring 27 and on the left side of the joint 1.

[0027] The outer wall of the fitting ring 27 fits against the inner wall of the equipment connection pipe 22, and the sealing ring 28 is located inside the equipment connection pipe 22. As the docking part 21 goes deeper, the sealing ring 28 seals the connection part.

[0028] Pull rings 29 are arranged at the top and bottom of the joint 1, and cord straps 3 are arranged on the inner sides of the two pull rings 29 and opposite to each other.

[0029] The left and right ends of the two cord straps 3 are respectively fixedly connected to the bottom ends of the two limit posts 24, and rollers are arranged on the inner side of the joint 1 and at the bent parts of the cord straps 3.

[0030] With the setting of the pull ring 29 and the cord 3, when it is necessary to disassemble the joint, by pulling the pull ring 29, the cord 3 is shortened, thereby overcoming the acting force of the limiting spring 25 and retracting the limiting post 24 into the inside of the slot 23, and then the docking part 21 can rotate.

[0031] A liquid pipe 4 is arranged on the right side of the joint 1, and holding notches 5 are arranged on the inner sides of the equipment connecting pipe 22 and the liquid pipe 4.

[0034] The first step: When in use, when the docking part 21 is screwed into the inside of the equipment connecting pipe 22, when entering, the limiting post 24 will retract into the inside of the slot 23, and when the top of the limiting post 24 is at the limiting hole 26, under the action of the limiting spring 25, the limiting post 24 is lifted. At this time, the docking part 21 is also connected to the equipment connecting pipe 22. Through the setting of the upper and lower two limiting posts 24, the connected docking part 21 and the equipment connecting pipe 22 are strengthened, improving the sealing and compressive resistance effects;

[0035] The second step: When it is necessary to separate the docking, with the setting of the pull ring 29 and the cord 3, when it is necessary to disassemble the joint, by pulling the pull ring 29, the cord 3 is shortened, thereby overcoming the acting force of the limiting spring 25 and retracting the limiting post 24 into the inside of the slot 23, and then the docking part 21 can rotate.

[0036] Compared with the related technology, a hydraulic joint assembly provided by the present utility model has the following beneficial effects:

[0037] By screwing the docking part 21 into the inside of the equipment connecting pipe 22, during the screwing process, the limiting post 24 will retract into the inside of the slot 23, and when the top of the limiting post 24 is at the limiting hole 26, under the action of the limiting spring 25, the limiting post 24 is lifted. At this time, the docking part 21 is also connected to the equipment connecting pipe 22. Through the setting of the upper and lower two limiting posts 24, the connected docking part 21 and the equipment connecting pipe 22 are strengthened, improving the sealing and compressive resistance effects.
