DETAILED DESCRIPTION

[0022] 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.

[0023] like Figure 1-7 As shown, a space chair that is easy to fold and unfold includes a chair frame and a chair cover 1, the chair frame includes two front telescopic support tubes, two rear telescopic support tubes and four leg tubes 2, the front telescopic support tubes, the rear telescopic support tubes and the leg tubes 2 are all rotatably connected to a connecting seat 3, four connecting grooves 301 are evenly spaced on the connecting seat 3, a first rotating member 4 is provided at one end of the front telescopic support tube, a second rotating member 5 is provided at one end of the rear telescopic support tube, the four leg tubes 2 are rotatably connected to the corresponding first rotating member 4 and second rotating member 5 on each connecting groove 301, and the chair cover 1 is detachably connected to the two front telescopic support tubes and the two rear telescopic support tubes.

[0024] During installation, first sleeve and connect the first rotating member 4 on one end of the front telescopic support tube, sleeve and connect the second rotating member 5 on one end of the rear telescopic support tube, then rotate and connect the first rotating member 4, the second rotating member 5 and one end of the leg tube 2 to the connecting groove 301, and perform the same operation on the four connecting grooves 301 to complete the installation of the chair frame. Finally, connect the corresponding connection positions on the chair cover 1 to the front telescopic support tube and the rear telescopic support tube to complete the installation of the chair.

[0025] When in use, by rotating the front telescopic support tube, the first rotating member 4 will rotate along the second rotating member 5. When the two rotating members hit a certain card point, the second rotating member 5 will be triggered to rotate, thereby driving the leg tube 2 to unfold. Similarly, when the rear telescopic support tube is rotated, the leg tube 2 will also be driven to unfold. When folding and storage is required, the same working principle applies. By pressing the leg tube inward, the first rotating member 4 and the second rotating member 5 will work in coordination, thereby driving the leg tube 2 to fold and completing the folding operation of the chair.

[0026] The space chair of the utility model has a simple structure. The chair frame can be supported by the connecting seat 3. Few installation accessories are required, and it is easy to disassemble and assemble. Moreover, the folding and unfolding operations are simple and quick, which greatly improves the convenience and stability of the chair. At the same time, since the front and rear support tubes are both telescopic structures, the storage volume of the chair can be greatly reduced.

[0027] Specifically, the front telescopic support tube and the rear telescopic support tube both include a first connecting tube 6 and a second connecting tube 7, and the rear telescopic support tube also includes a third connecting tube 8, and the third connecting tube 8 is connected between the first connecting tube 6 and the second connecting tube 7, one end of the first connecting tube 6 is connected to the sleeve hole 101 on the back of the chair cover 1, and the first rotating member 4 is sleeved on one end of the second connecting tube 7. The above design, through the design of the telescopic structure of the front and rear support tubes, wherein the telescopic structure can be a variety of existing technologies such as elastic pressing type, makes the front and rear support tubes easy to expand and fold, reduces the folded volume of the entire chair frame, and is easy to carry in the storage box.

[0028] It should be noted that the first connecting tube 6 and the second connecting tube 7 on the front and rear telescopic support tubes are accessories with the same structure, which simplifies the production process of the connecting tubes and realizes the versatility of the accessories. Then, according to usage requirements, multiple third connecting tubes 8 can be flexibly selected to enable the chair frame to form a variety of usage states to meet the use of different groups of people.

[0029] Specifically, the first rotating member 4 is provided with a first fixed seat 401, one end of which is sleeved on the second connecting tube 7, and the other end is extended to form a first rotating seat 402, one side of the first rotating seat 402 protrudes to form a fan-shaped block 403, and the second rotating member 5 is provided with a second fixed seat 501, one end of which is sleeved on one end of the leg tube 2, and the other end is extended to form a second rotating seat 502, and one side of the second rotating seat 502 is formed with a fan-shaped groove 503, the first rotating seat 402 and the second rotating seat 502 are in contact with each other, and are rotatably connected to the connecting groove 301 of the connecting seat 3 through the rotating shaft 9, and the fan-shaped block 403 rotates back and forth in the fan-shaped groove 503. With the above design, the first rotating seat 402 and the second rotating seat 502 are closely matched, and the design of the fan-shaped block 403 and the fan-shaped groove 503 can make the work between the two rotating seats more stable and smooth, thereby improving the efficiency of the chair's unfolding and storage.

[0030] Specifically, a baffle 302 is formed on the connecting groove 301, a stopper 303 is formed on the baffle 302, an arc segment 404 and a plane segment 405 are formed on the first rotating seat 402, a first rotating surface 406 is formed on the first fixed seat 401, a second rotating surface 504 and a third rotating surface 505 are formed on the second rotating seat 502, and a raised end surface 506 is formed therebetween, a fourth rotating surface 507 is formed on the second fixed seat 501, the arc segment 404 rotates along the fourth rotating surface 507, and the second rotating surface 504 rotates along the first rotating surface 406, so that the plane segment 405 conflicts with or disengages from the stopper 302, and the third rotating surface 505 conflicts with or disengages from the baffle 302. According to the above design, when the arc segment 404 rotates along the fourth rotating surface 507, the second rotating surface 504 rotates along the first rotating surface 406. When one end of the first rotating surface 406 hits the raised end surface 506, it will trigger the second rotating member 5 to rotate in the direction of the connecting seat 3 until the third rotating surface 505 abuts against the baffle 302. At this time, the plane segment 405 also abuts against the block 302, thus completing the stable expansion of the front and rear telescopic support tubes and the leg tubes 2; similarly, when folding is required, the leg tubes 2 are pressed together with force to disengage the third rotating surface 505 and the baffle 302 from rotating, and the raised end surface 506 will also touch the first rotating surface 406, thereby causing the first rotating member 4 to rotate and complete the folding of the leg tubes 2 and the front and rear telescopic support tubes; the above operation is simple and convenient, which greatly improves the convenience and stability of the chair.

[0031] Specifically, one end of the leg tube 2 is also sleeved with a support foot 10, and the other end of the support foot 10 is formed with a tilting block. The above design facilitates the leg tube 2 to stably contact the ground or other use carrier, thereby improving the stability and safety of the chair.

[0032] Specifically, a reinforcing plate 304 is further provided between two adjacent connecting grooves 301. The above design can improve the use strength of the connecting seat 3, thereby improving the use stability and safety of the chair.

[0033] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
