The difference between ordinary joints and hydraulic joints is that the hydraulic pressure is incredibly large, and the impact of a sudden burst of the hydraulic oil pipe is very large. Because the two joints are made of different materials, and most hydraulic quick connectors are available in one type with a one-way valve and one type without a one-way valve, the degree of pressure is different. Therefore, the existing protection is not enough, and different problems may occur, leading to instability of the device. Therefore, a hydraulic joint with a protective function is particularly needed.

[0003] However, the existing hydraulic joints with protective functions have a small flow rate due to the quick connectors in the current hydraulic joints, and the internal parts may be flushed with oil or water, which may cause the internal parts to rust, thereby causing rust to be mixed in the oil or water.

At this time, the liquid can pass through the block 401, and then flow through the sub- and female connectors, and can flow. At this time, the sub-sealing gasket 409 and the female sealing gasket 410 fit each other to prevent the liquid from flowing out, thereby achieving sealing protection. When the device is released, the spring 407 rebounds, driving the blocking connector 405 and the sliding shell 404 to rebound, so that the liquid is sealed and protected, and then the pipes and threaded interfaces 3 on both sides are connected.

[0022] Furthermore, the outer surface of the spring 407 fits with the surface of the support column 406, and a group of stop blocks 402 are provided in the male and female joints. Through the setting of the spring 407 and the support column 406, the spring 407 can be better rebounded, thereby driving the support column 406 and the sliding shell 404 to rebound.

When the first thread groove 506 and the second thread groove 507 are screwed, one end of the second sliding groove 502 and the sliding plate 503 also fit each other, so that the device is locked. At this time, the blocking joints 405 on both sides will be squeezed, so that a gap is created in the middle, so that the liquid can flow, and then it will drive The support column 406 and the sealing plug 408 can squeeze the air inside the cavity inward through the setting of the sealing plug 408, thereby pressing the column to block the joint 405 to keep it stable. At this time, the sliding shell 404 slides inward inside the first slide groove 403, thereby squeezing the spring 407, so that the spring 407 presses against the column block 402, thereby allowing the spring 407 to contract. At this time, the liquid can pass through the block 401, and then flow through the sub- and female joints to circulate. At this time, the sub-seal 409 and the female seal 410 fit each other to prevent the liquid from flowing out.
