Detailed Description

Embodiments of the present utility model are further described below with reference to the accompanying drawings.

As shown in fig. 1 to 3, the portable folding chair provided in this embodiment includes a supporting framework, a chair cover is disposed on the supporting framework, and the supporting framework is composed of two foldable framework bodies distributed symmetrically left and right and a plurality of connecting rods 1 for connecting the two foldable framework bodies, so that the foldable framework bodies on two sides can be connected through the connecting rods 1.

As shown in fig. 1 to 3, the foldable skeleton body includes a backrest 2, a grab bar 3, a support bar 4, a front leg 5 and a rear diagonal brace 6, one end of the grab bar 3 is hinged to the backrest 2, the other end is hinged to the front leg 5, one end of the support bar 4 is hinged to the front leg 5, the other end is hinged to the backrest 2, one end of the rear diagonal brace 6 is hinged to the front leg 5, and the other end is slidably connected to the bottom of the backrest 2.

Specifically, as a preference, a sliding rail 7 may be disposed on the inner side of the rear diagonal brace 6, and a connecting shaft 8 adapted to the sliding rail may be disposed on the outer side of the backrest rod 2, where the connecting shaft 8 is slidably disposed in the sliding rail 7. Of course, other sliding connection modes can be adopted, so that the folding and storage functions are realized. Through the novel slide rail mode of research and development for the chair realizes expanding and folding free switching through the slide rail. The sliding rail also provides mechanical support for the chair in the unfolded state. The structure of the folding chair is an innovative structure, and provides a brand new folding and unfolding mode, and the folding mode is shown in figure 2.
