Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and two specific embodiments.

Referring to fig. 1, the foldable suspension 1 of the present embodiment is mainly composed of a connecting frame 16, a hinge 3 and two folding frames 17. The two folding frames 17 are connected with the connecting frame 16 through the hinge 3 to form a foldable structure. The folding frame 17 and the connecting frame 16 are formed by connecting rods.

As shown in fig. 3, 4 and 5, the connecting rod of the present embodiment has a profile structure. The section bar is rectangular tube shape, and the inner chamber of section bar is cut apart into upper sub-chamber, lower sub-chamber, left sub-chamber and right sub-chamber by X-shaped brace rod 18, has both guaranteed the intensity of section bar, has also saved the materials of section bar, has reduced the cost of product. Round hole 13 is opened in brace rod 18, and lower sub-chamber has been seted up spout 11 and has been formed the gliding slide rail of slider (not shown in the figure) that can supply to be connected with the lifting hook with lower sub-chamber, at human aversion in-process, adjustable lifting hook and the hoist connected mode who bears the user or the position of slider in the spout, realize the user of hoist with adjustable form in order to adapt to different demands.

As shown in fig. 2, the left and right sides of the profile are respectively provided with a positioning groove 12. Hole grooves 121 are respectively formed in two sides of the bottom of the positioning groove 12 and used for avoiding burrs.
