DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figures 1 to 7 A foldable outdoor chair includes a seat 100, a backrest 200 and a support leg 300. The seat 100 includes two mutually parallel first support rods 110, and the two first support rods 110 are fixed by a connecting rod. The backrest 200 includes two mutually parallel second support rods 210, and the two second support rods 210 are fixed by a connecting rod. A first hinge seat 120 is provided at one end of the first support rod 110 facing the backrest 200, and a second hinge seat 220 is provided at one end of the second support rod 210 facing the seat 100, which cooperates with the first hinge seat 120. The first support rod 110 and the second support rod 210 are hingedly connected by the cooperation of the first hinge seat 120 and the second hinge seat 220, so that the backrest 200 and the seat 100 are rotatably connected. The first support rod 110 and the second support rod 210 can be brought close to each other by rotation, so that the seat 100 and the backrest 200 are folded.
[0025] Two supporting legs 300 are provided and are respectively connected to the two first supporting rods 110, so as to support the seat surface 100. The two supporting legs are connected by a connecting rod to ensure the stability of the supporting legs 300. The supporting legs 300 include a third supporting rod 310 and a fourth supporting rod 320. The third supporting rod 310 is provided with a third hinge seat 311, and the fourth supporting rod 320 is provided with a fourth hinge seat 321 matched with the third hinge seat 311, so that the third supporting rod 310 and the fourth supporting rod 320 are intersected and connected, so that the third supporting rod 310 and the fourth supporting rod 320 can be folded.
[0026] The first support rod 110 is provided with a connection block 130, and the third support rod 310 is provided with a first support shaft. The connection block 130 and the first support shaft are fixed by fasteners, so that the seat surface 100 and the third support rod 310 are fixed. At the same time, a positioning rod 140 is also provided on the first support rod 110, and a positioning groove 400 is provided on the fourth support rod 320. The positioning groove 400 includes a folding section 410 provided along the length direction of the fourth support rod 320 and a positioning section 420 bent toward the direction where the third support rod 310 is located. The positioning rod 140 is embedded in the positioning end to fix the first support rod 110 and the fourth support rod 320. When folding, the positioning rod 140 can slide out from the positioning section 420 to the folding section 410, and at the same time, the fastener between the connection block 130 and the first support shaft is loosened, so that the seat surface 100 and the support leg 300 can rotate, so that the seat surface 100 and the support leg 300 can be folded.
[0027] The distance between the third support rod 310 and the backrest 200 is greater than the distance between the fourth support rod 320 and the backrest 200, so that the third support rod 310 is in the front and the fourth support rod 320 is in the back. An armrest 500 is provided on the top of the support leg 300, and a fixing hole is provided at one end of the armrest 500 facing the backrest 200. A second support shaft is provided on the backrest 200, and the second support shaft is inserted into the fixing hole and fixed to the armrest 500 by fastening.
[0028] A mounting groove 510 is provided on the side of the armrest 500 facing the supporting leg 300, and a connecting member 600 is embedded in the mounting groove 510. A connecting groove 610 is provided on the side of the connecting member 600 facing the supporting leg 300, and a first limiting member 620 is provided in the connecting groove 610. A second limiting member 330 extending into the connecting groove 610 is provided on the fourth hinge seat 321, and the armrest 500 and the supporting leg 300 are fixed by the locking of the first limiting member 620 and the second limiting member 330.
[0029] Specifically, the first stopper 620 includes a first surface 621 facing the direction of the backrest 200, and the first surface 621 is provided with an arc groove. The second stopper 330 includes a support member 331 extending toward the connection groove 610, and the support member 331 is provided with a clamping member 332. When the clamping member 332 is embedded in the arc groove, the first stopper 620 and the second stopper 330 are mutually clamped. Since the first surface 621 faces the backrest 200, the opening direction of the arc groove faces the backrest 200. When the backrest 200 is pressed so that the armrest 500 has a tendency to move toward the direction of the backrest 200, the arc groove can hook the clamping member 332 to ensure the stability of the structure between the armrest 500 and the support leg 300. The first limiting member 620 also includes a second surface 622 opposite to the first surface 621. The second surface 622 is an arc surface. When folding, the movement of the armrest 500 will cause the second limiting member 330 to move in the connecting groove 610. The second surface 622 being an arc surface can guide the movement of the second limiting member 330, thereby facilitating the adjustment of the armrest 500 for easy folding.
[0030] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
