Detailed description of the invention

In order to the technical solution of the utility model is explained further, below by specific embodiment, the utility model is elaborated。

As shown in Figures 1 to 4, this utility model discloses a kind of folding camp chair shelf structure, it includes seat bracket 1, chair foot support 2 and is flexibly connected the connecting support seat 3 of seat bracket 1 and chair foot support 2, and on seat bracket 1, clearance fit has chair cloth 5(as shown in Figure 4)。

As it is shown in figure 1, described connecting support seat 3 is flap structure, this connecting support seat 3 is provided with the installing port 31 at four through upper and lower two ends, and the bottom up of each installing port 31 is provided with a skewed inclined-plane 32, makes the end face opening of each installing port 31 more than bottom surface opening。

Described seat bracket 1 includes at least two front support rod 11 and at least two back poles 12, and wherein the length of back pole 12 is greater than the length of front support rod 11。

Described chair foot support 2 includes at least four foot levers 21, and the top pivot joint of each foot lever 21 is fixed in each installing port 31 of connecting support seat 3。

One end of described two front support rods 11 and two back poles 12 is inserted in the top of each foot lever 3 respectively, the present embodiment is to form a necking down with the top of each foot lever 21, and the bottom jack of each front support rod 11 and back pole 12 is inserted in the necking down of corresponding foot lever 21, certainly, also can form necking down in the bottom of front support rod 11 and back pole 12 and directly be inserted in the jack on each foot lever 21 top, coordinate so that foot lever support 2 is planted with seat bracket 1。It is respectively provided with elastic threads 4 between each foot lever 21 with corresponding front support rod 11 or back pole 12, avoid foot lever 21 to depart from front support rod 11 or back pole 12 by the setting of elastic threads 4, and foot lever fixing for grafting can be strained with back pole with front support rod 11 or foot lever。

During this utility model combination, by in each installing port 31 of the top of each foot lever 21 traverse connecting support seat 3, the top pivot joint making each foot lever 21 is fixed on connecting support seat 3, again two front support rods 11 and two back poles 12 are planted and be matched with the top of each foot lever 21, certain foot lever 21 is directly equipped with elastic threads 4 with front support rod 11 or foot lever 21 with back pole 12, elastic threads 4 can be passed through footmuff (for not illustrating in figure) and be fixed on front support rod 11 or the top of back pole 12, and is fixed on the bottom of each foot lever 21。Due to the setting on installing port 31 inclined-plane 32, make each chair foot 21 outwards can launch for axle center with the pivoting point being articulated in connecting support seat 3, until the bottom surface of mounted mouth 31 is spacing, be now the deployed condition of this folding seat；Coordinate the chair cloth 5 shown in Fig. 4 again, this chair cloth 5 is square structure, its four angle sewings respectively are fixed with a reinforcing sleeve cloth 51, each reinforcing sleeve cloth 51 is formed with a trepanning 52 inserted for each front support rod 11 and each back pole 12 between the position and chair cloth 5 at Yi Bu center, each front support rod 11 and each back pole 12 are placed in the trepanning 52 of correspondence respectively, form the folding seat of an expansion。The folding chair period of the day from 11 p.m. to 1 a.m, first one end of two front support rods 11 and two back poles 12 is extracted from the trepanning 52 of chair cloth 5, again each rod member of seat bracket 1 is extracted from each foot lever 21 top of chair foot support 2, owing to being limited to the effect of elastic threads 4, each parts are made to be unlikely to depart from, and the compactest folding can be realized, reach minimum folding volume, to facilitate collection and to carry。

Coordinating shown in Fig. 1, Fig. 2, front support rod 11 and the back pole 12 of seat bracket 1 can be made up of more piece rod member, and namely the end of each rod member can form necking down and be beneficial to socket each other again, so can shorten the length after rod member folds further, and order more reasonable fold。During use, the pine oil binding force to each rod member, shake each rod member, under the resilient force of elastic threads 4, chair frame easily can be launched。

The above-mentioned front support rod 11 being made up of more piece rod member is or/and back pole 12 also can pass through with connecting rod realization, and namely one end of each connecting rod is fixed in a rod member, and the other end is pivot bush unit relation with adjacent rod member。

Certainly, each foot lever 21 of chair foot support 2 also can adopt more piece rod member to constitute。

Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field is to its suitably change done or modifies, and all should be regarded as without departing from patent category of the present utility model。
