DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the utility model.

[0023] Please refer to Figures 1-4, the present utility model discloses a stable director's chair, which comprises a chair body 1. The chair body 1 includes two symmetrically arranged side frames 11. A scissors frame 12 is hinged between the two side frames 11. Both ends of the top of the scissors frame 12 are fixedly provided with sliding rods 13. A flexible seat cushion 16 is sleeved on the two sliding rods 13 together. Two limiting pull rods 17 are also hinged on the scissors frame 12. One ends of the two limiting pull rods 17 far away from the scissors frame 12 are respectively hinged to the inside of the two side frames 11. The setting of the limiting pull rods 17 limits the descending distance of the sliding rods 13, ensuring the stability of the sliding rods 13. When not in use, move the two side frames 11 relatively. Since both ends of the bottom of the scissors frame 12 are hinged to the two side frames 11, and both ends of the top of the scissors frame 12 are fixed to the two sliding rods 13, moving the two side frames 11 relatively will cause the scissors frame 12 to change from a cross shape to a straight shape. At the same time, the two sliding rods 13 move upward and relatively, making the two side frames 11 approach each other. The settings of the flexible seat cushion 16 and the flexible backrest 15 do not affect the folding operation of the side frames 11. After folding, the occupied space of the chair body 1 is greatly reduced, and it is more convenient to transport and carry. The side frame 11 is rectangular. When the sliding rod 13 descends, the top of the side frame 11 naturally forms an armrest, making it more comfortable to use. The material of the sliding rod 13 is 6063 aluminum alloy, and the material of the side frame 11 is 6061 aluminum alloy, and it undergoes three-layer surface treatment. The first-layer surface treatment is to spray the base color, the second-layer surface treatment is to brush the paint color, and the third-layer surface treatment is to spray transparent plastic, making it more durable and beautiful.

[0024] Specifically, the number of the scissors frames 12 is at least two, and both ends of the top of the two scissors frames 12 share two sliding rods 13. The scissors frame 12 is two aluminum alloy tubes that are hinged in the middle and can be unfolded in a cross shape. The setting of the two scissors frames 12 ensures the stability of the sliding rods 13, and the user sits more stably.

[0025] Specifically, a backrest rod 14 is fixedly provided at the top of the side frame 11. The backrest rod 14 is inclined. The inclined backrest rod 14, in cooperation with the side frame 11, conforms to the ergonomic design, and the user feels more comfortable when using it.

[0026] Specifically, a flexible backrest 15 is sleeved on the two backrest rods 14 together. The materials of the flexible backrest 15 and the flexible seat cushion 16 are both one of waterproof Oxford cloth or Oxford mesh cloth. Oxford mesh cloth has good air permeability and better effect in summer. Waterproof Oxford cloth has excellent waterproof performance.

[0027] Specifically, a storage groove 18 is formed at the bottom of one side of the side frame 11 and is located below the backrest rod 14. At the top of the inner wall of the storage groove 18, a support rod 19 is hinged. An activity sleeve 191 is movably sleeved outside the support rod 19. Both sides of the activity sleeve 191 are hinged with support arms 192, and the ends of the two support arms 192 away from the activity sleeve 191 are respectively hinged with both sides of the inner wall of the storage groove 18. A number of positioning holes 193 are formed on one side of the activity sleeve 191. A button 194 is arranged inside the support rod 19 through a spring. One side of the button 194 extends outside the support rod 19, and at least two positioning pins 195 are arranged on the other side. One end of the positioning pin 195 is tapered and extends into the interior of one of the positioning holes 193. With the tapered positioning pin 195, it is more smooth to insert it into the interior of the positioning hole 193. When taking out the activity sleeve 191, press the button 194 to compress the spring. The button 194 drives the positioning pin 195 to disengage from the connection with the positioning hole 193, and then the support rod 19 can be flipped out and taken out. During the process of flipping out and taking out the support rod 19, the activity sleeve 191 slides on the support rod 19, and at the same time the activity sleeve 191 drives the support arms 192 to flip. After the bottom end of the activity sleeve 191 contacts the ground, insert and lock it through the positioning pin 195. The activity sleeve 191 and the support rod 19 cannot move relative to each other, realizing the locking of the activity sleeve 191, so that the activity sleeve 191, the support arms 192 and the side frame 11 form a stable triangle, making it more stable when the user leans on the flexible backrest 15 and not prone to tipping over.

[0028] In summary, for this stable folding director's chair, moving the two side frames 11 relatively or away from each other can complete the folding and unfolding of the chair body 1. By pressing the button 194, the locking between the support rod 19 and the activity sleeve 191 can be released, and the activity sleeve 191 can be flipped out to support the side frame 11, ensuring the stability of the backward tilt of the side frame 11 and not prone to tipping over, making it more stable to use. Moreover, when the activity sleeve 191 is not in use, it can be stored inside the storage groove 18 without affecting the appearance of the chair body 1, meeting the user's usage requirements.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
