Detailed Description

The technical solution of the present invention will be described in detail with reference to the accompanying drawings. In the description of the present application, it is to be understood that the terms "upper", "lower", "left", "right", "front", "rear", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings.

The specific embodiment is as follows:

the staggered-port sealed hydraulic pipe joint illustrated in fig. 1 to 3 includes a first joint 1 and a second joint 2 inserted into each other in a staggered manner, the first joint 1 includes a first base 101 having a through hole in the middle thereof through which a liquid can flow, a first pipe joint 102 capable of being connected to a hydraulic pipe is formed integrally with the first base at one end of the first base 101, two concentric cylindrical first sockets 103 formed integrally with the first base 101 are formed at the other end of the first base 101, and an external thread 104 is formed at an outermost end of the first socket 103. The second joint 2 comprises a second base 201 with a through hole in the middle for liquid to flow through, one end of the second base 201 and the second base are integrally formed to be provided with a second pipe interface 202 capable of being connected with a hydraulic pipe, the other end of the second base 201 is provided with two concentric cylindrical second sockets 203 integrally formed with the second base 201, and the second pipe interface 202 is sleeved with a clamping sleeve nut 4 capable of being connected with the external thread 104. The root of each of the first and

second sockets

103 and 203 is provided with a rubber packing 3 having a different radius but the same thickness.

For a better fit of the first connector 1 and the second connector 2, the axial length of each first socket 103 located in the first connector 1 and each second socket 203 located in the second connector 2 is the same, i.e. H1 is equal to H2. Because the first inserting opening 103 and the second inserting opening 203 are the same in length, four sealing barriers can be formed when the first inserting opening and the second inserting opening are inserted into each other relatively, and the sealing effect is effectively improved.

As shown in fig. 2 and 3, the radial distance between two adjacent first inserting holes 103 is equal to the radial distance between two adjacent second inserting holes 203, and both are W1; the radial width of the first socket 103 inside the first connector 1 is equal to the radial width of the second socket 203 outside the second connector 2, uniformly W2. In order to achieve an effective fit when the first socket 103 and the second socket 203 are inserted into the opposing sockets, W1 is 0.5mm to 1mm larger than W2, i.e. the radial distance between two adjacent first sockets and the radial distance between two adjacent second sockets are 0.5mm to 1mm larger than the radial width of the first socket inside the first joint and the radial width of the second socket outside the second joint, so that a clearance fit is formed between the two sockets on the two joints.

When the hydraulic pipe joint is used, after the first joint and the second joint are inserted into each other, the ferrule nut is connected with the external thread 104 positioned at the outer end of the first joint 1 by rotating the ferrule nut 4 rightwards, and the ferrule nut 4 is screwed so that four sealing barriers can be formed between the first joint 1 and the second joint 2, and leakage of a hydraulic system is effectively prevented.
