Abstract

The utility model discloses an improvement of folding chair structure which comprises a holder frame, a first leg, a back leg and a connecting sheet. A folding four connecting rod structure is formed between the first leg, the back leg, the holder frame and the connecting sheet. The first leg is connected with the holder frame by adding a strengthening sheet. The utility model can achieve the aim of improving the intensity of the connecting place of the folding chair only by adding a strengthening sheet with simple and practical structure.

Description

A kind of improvement of folding chair structure
Technical field: the utility model relates to the improvement of a kind of folding seat support frame and supporting leg bindiny mechanism.
Technical background: folding seat is made up of seat frame, foreleg, back leg, be connected by rivet between seat frame and foreleg, the back leg, form rotatable connection, in order to improve the existing way of bonding strength is the diameter that increases rivet, this has improved the intensity of junction certainly, but, the seat frame of its correspondence of rivet diameter that strengthens, the jack of chair legs are also wanted corresponding increase, this has reduced the intensity of other member of junction again, and when rivet diameter diminishes, though the intensity of seat frame, chair legs is met, the intensity of rivet is not enough again.
Summary of the invention: folding seat of the present utility model comprises a frame, foreleg, back leg, brace, constitutes a folding quadric chain between foreleg, back leg, seat frame, the brace, is connected by reinforced sheet of increase between its foreleg and the seat frame.
Reinforced sheet described in the utility model can be a sheet, and it has a face and the side of seat frame to fit, as Fig. 2.
Reinforced sheet described in the utility model also can be a dihedral, and its interior angle is fitted with the side of seat frame, as Fig. 3.
Reinforced sheet of the present utility model also is not limited to above-mentioned shape, as long as and reach and increase the reinforced seat frame and be connected with foreleg, arbitrary shape and structure all can.The utility model only increases a reinforced sheet in existing structure, can realize improving the purpose of folding seat junction intensity, and is simple and practical.
Description of drawings: Fig. 1 is the utility model stereogram; Fig. 2 is first kind of reinforced sheet schematic diagram; Fig. 3 is second kind of reinforced sheet schematic diagram; Fig. 4 is the utility model folding seat embodiment 1 structural representation; Fig. 5 is the utility model folding seat embodiment 2 structural representations; Fig. 6 is the utility model folding seat embodiment 3 structural representations.
The specific embodiment: embodiment 1: as shown in Figure 4, foreleg 2 is riveted into a rotatable hinge with brace 4 by rivet 2.1, foreleg 2 is riveted into a rotatable hinge with reinforced sheet 5 by rivet 1.2, seat frame 1 fuses by rivet 1.1,1.3 and reinforced sheet 5, seat frame 1 is riveted into a rotatable hinge with back leg 3 by rivet 4.3, back leg 3 is riveted into a rotatable hinge with brace 4 by rivet 4.2, thereby constitutes a four-bar linkage structure that can fold.Wherein 4.1 of back leg plugs are opened the back position-limiting action.
Embodiment 2: as shown in Figure 5: foreleg 2 is riveted into a rotatable hinge with reinforced sheet 5 by rivet 1.2, seat frame 1 fuses by rivet 1.1,1.2 and reinforced sheet 5, brace 4 is riveted into a rotatable hinge with seat frame 1 by rivet 1.3, brace 4 is riveted into a rotatable hinge with back leg 3 by rivet 4.2, back leg 3 be connected hinge 6 and link into an integrated entity by self-tapping screw 6.1, foreleg 2 is connected hinge 6 and rivets into a rotatable hinge by rivet 2.1 with back leg, thereby constitutes a four-bar linkage structure that can fold.Position-limiting action after wherein 4.3 in rivet on the seat frame is opened.
Embodiment 3: as shown in Figure 6: connect hinge 6 and link into an integrated entity by self-tapping screw 6.1 with lead 3.1, lead 3.2 can slide up and down in the fairlead 3.1 of back leg, be welded to connect sheet 4 on the back leg 3, brace 4 is riveted into a rotatable hinge with seat frame 1 by rivet 1.3, reinforced sheet 5 is riveted into a rotatable hinge with foreleg 1 by rivet 1.2, seat frame 1 fuses by rivet 1.1,1.2 and reinforced sheet 5, foreleg 2 is riveted into a rotatable hinge with being connected hinge 6 by rivet 2.1, thereby constitutes a crank-rocker mechanism that can fold.When connecting hinge 6 with fairlead 3.1 diebacks, folding seat opens to user mode.
