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

[0022] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a quick-assembly structure for an iron chair, including a seat 1, a support leg 2 slidably connected to the lower surface of the seat 1, a pull block 3 slidably connected to the inside of the support leg 2, a slider 4 fixedly connected to the outer wall of the pull block 3, the outer wall of the slider 4 slidably connected to the inside of the support leg 2, a column 5 slidably connected to the inside of the slider 4, the outer wall of the column 5 fixedly connected to the inside of the support leg 2, one end of a first spring 6 fixedly connected to the lower surface of the slider 4, the other end of the first spring 6 fixedly connected to the inside of the support leg 2, a first rotating shaft 7 fixedly connected to the inside of the slider 4, a rotating plate 8 rotatably connected to the outer wall of the first rotating shaft 7, a second rotating shaft 9 fixedly connected to the inside of the rotating plate 8, a locking block 10 rotatably connected to the outer wall of the second rotating shaft 9, the outer wall of the locking block 10 slidably connected to the inside of the seat 1, a second spring 11 fixedly connected to the outer wall of the locking block 10, and a support assembly provided on the upper surface of the seat 1.

[0023] Specifically, the four corner support legs 2 provide stable support for the seat 1. The slider 4 slides inside the support legs 2 and fixes the pull block 3. By pressing down the pull block 3, the slider 4 can slide. The upright 5 is fixed inside the support legs 2 and provides support for the sliding of the slider 4. The first spring 6 is compressed due to the sliding of the slider 4. The slider 4 supports the first rotating shaft 7, which allows the rotating plate 8 to rotate. The rotating plate 8 supports the first rotating shaft 7 and the second rotating shaft 9. In turn, the second rotating shaft 9 drives the locking block 10 to slide through the rotation of the rotating plate 8. The second spring 11 is also compressed due to the sliding of the locking block 10, aligning the seat 1 with the support legs 2. The locking block 10 is locked inside the seat 1 due to the rebound of the first spring 6 and the second spring 11, thus installing and fixing the seat 1 and the support legs 2.

[0024] Reference Figure 1 The support component includes a connecting block 12, the lower surface of which is slidably connected to the upper surface of the seat 1, a backrest 13 is fixedly connected to the upper surface of the connecting block 12, and an armrest 22 is fixedly connected to the upper surface of the seat 1.

[0025] Specifically, the seat 1 supports the connecting block 12, the connecting block 12 fixes the backrest 13, the backrest 13 supports the back of the human body, and the seat 1 fixes the armrest 22, which can provide support for the human body.

[0026] Reference Figure 1 and Figure 3 A sleeve 14 is fixedly connected inside the connecting block 12. The outer wall of the sleeve 14 is slidably connected inside the seat 1. A button 15 is slidably connected inside the sleeve 14. A push rod 16 is fixedly connected to the lower surface of the button 15. The outer wall of the push rod 16 is slidably connected inside the sleeve 14. One end of a spring 17 is fixedly connected to the lower surface of the button 15. The other end of the spring 17 is fixedly connected inside the sleeve 14. A push plate 18 is fixedly connected to the lower surface of the push rod 16. The outer wall of the push plate 18 is slidably connected inside the sleeve 14. A locking rod 19 is slidably connected to the lower surface of the push plate 18. The outer wall of the locking rod 19 is rotatably connected inside the sleeve 14 and inside the seat 1. A fixed shaft 20 is rotatably connected inside the locking rod 19. The outer wall of the fixed shaft 20 is fixedly connected inside the sleeve 14. One end of a spring 21 is fixedly connected to the outer wall of the locking rod 19. The other end of the spring 21 is fixedly connected inside the sleeve 14.

[0027] Specifically, the sleeve 14 is fixed inside the connecting block 12 and supports the push block 15. The push block 15 fixes the push rod 16, and the push rod 16 fixes the push piece 18. Pressing the push block 15 will cause the push piece 18 to rotate through the sliding of the push rod 16. The spring 17 will be squeezed due to the sliding of the push rod 16, which will cause the locking rod 19 to rotate due to the sliding of the push piece 18. The fixed shaft 20 is fixed inside the sleeve 14 and supports the locking rod 19, providing stable support for the rotation of the locking rod 19. The spring 21 will also be squeezed due to the rotation of the locking rod 19. When the connecting block 12 is aligned with the chair seat 1, the reverse sliding of the push block 15 will cause the locking rod 19 to be locked inside the chair seat 1 due to the rebound of the spring 17 and the spring 21, thus completing the splicing of the chair seat 1 and the connecting block 12.

[0028] Working principle: When this structure is needed, the seat 1 and support leg 2 are assembled. Pulling the pull block 3 inside the support leg 2 causes the slider 4 to slide on the outer wall of the column 5 and compress the first spring 6. During the sliding process, the slider 4 drives the rotating plate 8 to rotate through the internal first rotating shaft 7. The rotating plate 8 drives the locking block 10 to slide through the internal second rotating shaft 9 and compress the second spring 11. At this time, the seat 1 and support leg 2 are aligned. The pull block 3 is released, and the rebound of the first spring 6 and the second spring 11 can lock the locking block 10 into the interior of the seat 1 to fix the seat 1 and support leg 2, achieving quick assembly and saving installation time. When it is necessary to assemble the seat 1 and connecting block 12, press the button 15 to make it slide inside the sleeve 14. When the button 15 slides... The push rod 16 will slide and compress the spring 17. The sliding of the push rod 16 will cause the push plate 18 to slide inside the sleeve 14. During the sliding process of the push plate 18, it will compress the locking rod 19 on the lower surface, causing it to rotate through the fixed shaft 20 and compress the spring 21, thus retracting the locking rod 19 into the sleeve 14. At this time, the connecting block 12 is aligned with the seat 1, and the button 15 is released. The rebound of the spring 17 and the locking rod 19 can lock the locking rod 19 into the seat 1, fixing the seat 1 and the connecting block 12. This achieves the effect of quick installation and use, and quick disassembly for easy storage when not in use. This structure can not only achieve the effect of quick assembly of the seat 1 and the support leg 2, saving installation time, but also achieve the effect of quick installation and disassembly of the seat 1 and the connecting block 12, and convenient storage when not in use.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
