Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.

As shown in fig. 1-3, the swing hose structure includes a right connecting flange 1 used as a fixed end and a transition flange 2 used as a swing movable end, the end of the transition flange 2 is connected with a left inner connecting flange 3, and a left outer connecting flange 4 is sleeved outside one end of the left inner connecting flange 3 far away from the transition flange 2;

in the use, through flange joint's mode, can reduce the degree of difficulty of installation, improve the stability after the installation simultaneously.

Connecting pipe 5 has been pegged graft to right flange 1 inside, and the outside cover of one end that right flange 1 was kept away from to connecting pipe 5 is equipped with sways hose outlet flange 6, sways and is connected with outer bellows 7 between hose outlet flange 6 and the left outer flange 4, is connected with interior bellows 8 between left in-connection flange 3 and the connecting pipe 5, and the outside of interior bellows 8 is located to outer bellows 7 cover.
