The utility model can arbitrarily adjust the direction of the sewage inlet of the aircraft sewage truck, facilitate the sewage truck to dock with the aircraft in any direction, avoid the problem of deformation of the sewage pipe due to forced turning caused by incorrect docking direction, and solve the problems of reduced sewage discharge efficiency and even blockage of the sewage discharge pipeline.

However, the entire sewage pipe is composed of a fixed pipe section and a rotating pipe section, and the positions of sewage outlets of different models are different. If only the rotating pipe section is rotated, there will still be a phenomenon that the sewage outlet of the aircraft cannot be docked.

[0005] In view of this, the present utility model is proposed. Utility Model Content

When the position of the connecting hose is adjusted, the first guide pipe is rotated, and the first guide pipe drives the second guide pipe and the connecting hose to rotate, so that the connecting hose is adjusted to a position convenient for connecting with the sewage outlet of the aircraft. When the first guide pipe rotates, the annular groove and the connecting block are matched, so that the first guide pipe can drive the mounting ring to rotate on the inner wall of the mounting seat.
