[0005] Through the above technical solution, when it is necessary to connect the pipe fitting to the above hydraulic joint, the pipe fitting is firstly put on the outside of the plurality of pre-alignment units so that the inner wall of the pipe fitting is tightly against the outer wall of the support section. At this time, the plurality of pre-alignment units can support and position the pipe fitting so that the central axis of the pipe fitting coincides with the central axis of the joint body. Then, the pipe fitting is pushed close to the joint body so that the pipe fitting and the joint body are tightly against each other. Finally, the pipe fitting and the joint body can be connected by controlling the rotation of the pipe fitting. By supporting and positioning the pipe fitting through the plurality of pre-alignment units, there is no need for workers to manually maintain the position of the pipe fitting, so that the above joint body has the advantages of higher docking accuracy and higher docking efficiency.

[0006] Preferably, a guiding slope is provided at the end of the supporting section away from the connecting section, and the distance between the guiding slope and the central axis of the joint body gradually increases toward one side of the joint body.

[0008] Preferably, a mounting groove is provided on the inner wall of the end of the joint body, and the connecting section is fixedly connected in the mounting groove.

[0009] Through the above technical solution, the connecting section is fixedly connected in the installation groove, which can effectively increase the contact area between the connecting section and the joint body, thereby improving the connection strength between the connecting section and the joint body.

[0010] Preferably, the end of the supporting section close to the connecting section is tightly abutted against the end of the joint body.

[0011] Through the above technical solution, the support section and the joint body are tightly pressed against each other, so that in the process of pushing the pipe to move, it is not easy for the end of the pipe to be stuck between the support section and the joint body.

[0012] Preferably, an arc-shaped connecting plate is provided between two adjacent supporting segments, and an outer side wall of the arc-shaped connecting plate is engaged with an outer side wall of the supporting segment.

[0013] Through the above technical solution, the arc-shaped connecting plate arranged between two adjacent supporting sections can provide more effective support for the pipe fittings, so that the pipe fittings are less likely to deform and can move more smoothly.

[0014] Preferably, connecting grooves are provided on both sides of the supporting section, and connecting protrusions are provided on both ends of the arc-shaped connecting plate, and the connecting protrusions are clamped in the corresponding connecting grooves.

[0015] Through the above technical solution, the connecting protrusions are clamped in the corresponding connecting grooves, which can increase the contact area between the arc-shaped connecting plate and the supporting section, thereby increasing the connection strength between the arc-shaped connecting plate and the supporting section.

[0016] Preferably, rubber ribs are provided on both sides of the end of the arc-shaped connecting plate, and the rubber ribs are tightly pressed against the supporting section.

[0017] Through the above technical solution, the rubber ribs are tightly pressed against the support segments, so that there is a large static friction between the rubber ribs and the support segments, which can effectively improve the connection stability between the arc-shaped connecting plate and the support segments.
