In particular, plastics that are desired to be made relatively easy to mold, for example, molded, for example, in an injection molding process, can be used to prepare a material of the rotary joint sleeve element. It is also conceivable to use other materials such as rubber.

It is possible to keep the seat cushion by at least one rotary joint. Specifically, the seat cushion of the rear semi-seat seat of the motor vehicle can be entered in the vertical position by such a rotary joint to increase the storage space or storage capacity inside the vehicle. For this purpose, the lower end of the seat is typically attached to the backrest of the seat or the vehicle body portion of the vehicle by at least one rotary joint.

At the same time,OEM thread coector avoid the aoying noise or vibration in the rotary joint, or prevent accidental movement of folded or raised seat cushions. The positionable rotary joint rotating body forms a cavity between the main junction tube, and the cavity is sealed with an end cover, and the left segment and the right segment are disposed between the cavity.

Thus, the wall is also opened on the wall of the rotary joint rotating body, respectively, the corresponding position corresponding to the sub-spray tube, the main feed tube, the sub-tube, and the position of the side spray tube on the main joint pipe of the rotary joint The opening, the main joint pipe is opened to the main feed tube, the sub-tubular tube, respectively, open the main feed tube, the sub-tissue, and the recovery chamber.

In summary, due to the above technical solution, the beneficial effect of the positionable rotary joint is: 360 degrees to rotate, and can be positioned; multi-chael design, compact structure, manufacturing and installation are very convenient.
