[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5As shown, an easy-to-install chair structure includes a connecting frame 1, legs 2, and a seat cushion 3. A backrest 4 is fixedly installed on the connecting frame 1. The legs 2 are fixedly connected to the connecting frame 1 via an embedded positioning fixing connection component 5. A support block 6 is fixedly installed on the inner wall of the connecting frame 1. A connector 7 is fixedly installed at the bottom of the seat cushion 3, and the connector 7 is located at the top of the support block 6. A connecting strip 8 is fixedly installed at the bottom of the support block 6. An installation groove is provided on the connecting strip 8, and a screw-type pin fixing component 9 is installed in the installation groove. The screw-type pin fixing component 9 is used to fix the connector 7 with a pin. In use, the legs 2 are securely installed on the connecting frame 1 via the embedded positioning fixing connection component 5. The embedded positioning fixing connection component 5 solves the problem of the connection holes being difficult to align. Then, the connector 7 of the seat cushion 3 is aligned and placed on the top of the support block 6. Subsequently, the screw-type pin fixing component 9 is operated in the installation slide to pass the pin through the connector 7 and tighten it, thereby achieving a firm connection between the seat cushion 3 and the connecting frame 1. The whole process is simple and quick, and the chair can be assembled without complicated tools, making it convenient for users to easily install or disassemble the chair as needed.

[0023] The embedded positioning fixed connection assembly 5 includes a square sliding block 501 and a square positioning block 502. The square sliding block 501 is slidably inserted into a square groove opened on the side wall of the connecting frame 1, and the square positioning block 502 is fixed in a through-hole groove opened on the support leg 2. One end of the square sliding block 501 is elastically connected to the inner wall of one end of the square groove through a return spring 503, and the other end of the square sliding block 501 is inserted into the through-hole groove. Corresponding threaded holes are opened on the square sliding block 501 and the square positioning block 502, and fixing bolts 504 are inserted into the threaded holes. In use, the square sliding block 501 is... 01 Slide the square slide block 501 into the square slide groove of the connecting frame 1, and use the return spring 503 to maintain the elastic connection. Then, align the square positioning block 502 with the through hole groove of the support leg 2, and push the square sliding block 501 into the through hole groove. When the square sliding block 501 is not aligned with the through hole groove, the inner wall of the support leg 2 pushes the square sliding block 501, causing the return spring 503 to compress and the square sliding block 501 to retract into the square slide groove until the square sliding block 501 is aligned with the through hole groove. Then, screw in the fixing bolt 504 and lock it with the thread to achieve a stable connection between the support leg 2 and the connecting frame 1. The installation is simple and quick.

[0024] The screw-type pin fixing assembly 9 includes a bidirectional threaded rod 901, which is rotatably mounted on the inner wall of one end of the mounting groove via a rotating joint 902. A screw-on handle 903 is fixedly mounted on one end of the bidirectional threaded rod 901, located outside the connecting strip 8. Two threaded sliders 904 are mounted on the bidirectional threaded rod 901, which are slidably engaged in the mounting groove. The two threaded sliders 904 are located at the opposite thread ends of the bidirectional threaded rod 901. Two threaded sliders 904 are respectively fixedly mounted with a first fixing pin 905 and a second fixing pin 906. The first fixing pin 905 and the second fixing pin 906 are fixedly connected to the two threaded sliders 904 through L-shaped connecting blocks 907. The first fixing pin 905 and the second fixing pin 906 are respectively inserted into the connectors 7 located on both sides of the seat cushion 3. In use, turning the handle 903 drives the bidirectional threaded rod 901 to rotate, causing the two threaded sliders 904 to slide relative to or away from each other in the mounting groove. Align the first fixing pin 905 and the second fixing pin 906 with the connectors 7 on both sides of the seat cushion 3 and continue to turn until the two fixing pins are inserted into the connectors 7, achieving a stable fixation. The operation is simple, the pin fixing is quick, and it is convenient to disassemble and assemble, effectively ensuring the connection stability between the seat cushion 3 and the chair.
