detailed description

In order to further explain the technical solution of the utility model, the utility model is described in detail through specific examples below.

As shown in Figures 1 to 4, the utility model discloses a folding chair frame structure, which includes a seat support 1, a chair foot support 2 and a connecting support frame that movably connects the seat support 1 and the chair foot support 2 3. The seat support 1 can be equipped with a seat cloth (not shown in the figure).

The connecting support frame 3 is integrally formed by plastic material, and the connecting support frame 3 includes two groups of connecting frames 31 and a connecting rod 32 connecting the two connecting frames 31 in a transverse direction. Each group of connecting frames 31 is composed of two V-shaped pipes 30 pairs The buckle is fixed together by the side walls of the legs of the two, and the two ends of the connecting rod 32 are respectively stretched and fixed in the space formed by the two V-shaped tubes of the two connecting frames 31 buckles, and the two ends of each V-shaped tube 30 The ports of the legs are used for insertion and cooperation of the rods of the seat bracket 1 and the chair leg bracket 2; an elastic rope 4 is inserted between the two rods of the same V-shaped tube 30, that is, the elastic rope 4 passes through The V-shaped pipe 30 connects the two rods. The connecting rod 32 connecting the supporting frame 3 is a hollow pipe body with at least one opening 321 , and the metal reinforcing pipe 5 is movably inserted in the connecting rod 32 .

The seat frame 1 includes at least two front struts 11 and at least two rear leaner struts 12 , wherein the length of the rear leaner struts 12 is greater than the length of the front struts 11 .

The chair leg bracket 2 includes at least four leg rods 21 , and a leg cover 6 is respectively provided at the bottom of each leg rod 21 .

One end of the two front struts 11, two rear support rods 12 and four foot rods 21 are respectively inserted in each V-shaped pipe 30 connecting the support frame 3, and the other ends are respectively sleeved with a pipe plug 7, a pipe plug 7 A connecting piece 71 protrudes toward one end of the rod, and an opening 72 is formed on the connecting piece 71. The setting of the connecting piece 71 and the opening 72 is convenient for the threading and fixing of the elastic cord.

As shown in Fig. 2, the leg ports of the V-shaped tubes 30 of the connecting support frame 3 form the jacks of the rods of the seat bracket 1 and the chair leg bracket 2. Of course, the V-shaped tubes 30 can also be The ports of the legs form a constriction and are inserted into the rods of the seat frame 1 and the chair leg frame 2 . The setting of the V-shaped tube 30 is to facilitate the threading of the elastic rope 4 .

When combined, an elastic rope 4 is threaded through each V-shaped pipe 30 connecting the support frame 3, and the two ends of the elastic rope 4 are connected to the rods that are matched with the respective V-shaped pipes 30, and then penetrated to the ends of the pipe plugs 7 of each rod. Fix in the opening 72, so that the seat support 1, the chair foot support 2 and the connecting support frame 3 form a folding chair frame.

When the chair is in use, it is only necessary to insert the rods of the seat support 1 and the chair foot support 2 into the ports connecting the V-shaped tubes 30 of the support frame 3; The rods of the seat bracket 1 and the chair foot bracket 2 can be pulled out from the ports connecting the V-shaped pipes 30 of the support frame 3. Due to being limited by the effect of the elastic rope 4, each part will not be separated, and it can Realize the most compact folding and the smallest folding volume to facilitate storage and carrying.

As shown in Figure 1 and Figure 2, the front support rod 11 and the rear support rod 12 of the seat support 1 can be made of multi-section rods, that is, the ends of each rod can form a neck to facilitate mutual socketing , so that the length of the folded rod can be further shortened, making the fold more reasonable. When in use, loosen the binding force on each rod, shake each rod, and under the action of the elastic force of the elastic rope 4, the chair frame can be easily unfolded.

The above-mentioned front strut 11 or/and rear support rod 12 formed by multi-section rods can also be matched by connecting rods, that is, one end of each connecting rod is fixed in a rod, and the other end is movable with the adjacent rod. Socket relationship.

Certainly, each leg rod 21 of the chair leg bracket 2 can also be made of multi-section rods.

In summary, after adopting the above scheme, the utility model utilizes two interlocking V-shaped tubes 30 to form a connecting frame 31, and then connects the two connecting frames 31 through a connecting rod 32 to form a connecting support frame 3 of a folding chair. The ports of the legs of the shaped tube 30 form jacks for the rods of the seat bracket 1 and the chair leg bracket 2, thus forming a folding chair, and the elastic ropes 4 passing through the V-shaped tubes realize the folding of each rod of the folding chair. The folding of the parts and the connecting support frame 3 achieves the effects of simple structure, low manufacturing cost, more compact folded volume, and easier carrying and storage. The connecting support frame 3 is integrally formed of plastic material, which not only ensures its stability, but also is quick to process, and the cost of the plastic material is low and light, making it easier to carry. In addition, the reinforcing tube 5 disposed in the connecting rod 32 increases the supporting strength of the connecting support frame 3 at the same time.

The above-mentioned embodiments and drawings do not limit the product form and style of the present utility model, and any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present utility model.
