Technical Field
[0001] This utility model relates to the field of furniture and chair technology, specifically a furniture and chair that is easy to assemble and disassemble. Background Technology
[0002] As one of the most commonly used pieces of furniture, chairs are traditionally non-detachable, bulky, and heavy. They are mostly fixed with nails and made into a one-piece structure. Most households have some wooden chairs for entertaining guests. However, when the chairs are not needed, they need to be stored away. But one-piece chairs take up a lot of space and are not convenient to store.
[0003] Some existing chairs typically separate the seat and backrest for individual storage or transport. The seat and backrest are then reassembled before use. Alternatively, a rotatable connection between the seat and backrest allows for easy folding and rotation during storage and transport. However, in practice, the fixed-length legs are difficult to retract and fold during use. Furthermore, most chair legs are secured to the seat with screws, requiring tools to remove and reassemble each screw individually. After disassembly, the legs are difficult to store and are prone to loss, hindering the chair's future use.
[0004] Based on this, a furniture chair that is easy to assemble and disassemble is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0026] Example 1
[0027] In one embodiment, such as Figures 1-8 As shown, a furniture chair that is easy to assemble and disassemble includes a seat panel 11 and a seat back 12. A hinge rod 13 is fixedly provided on one side of the seat panel 11. The hinge rod 13 has symmetrical hinge grooves. A hinge seat 14 is fitted in each hinge groove. The hinge seat 14 is fixedly provided on one side of the seat back 12. A push rod 15 is slidably provided inside the hinge rod 13. The push rod 15 has a fixing component for fixing the position of the seat back 12. Several mounting seats 18 are fixedly provided at the bottom end of the seat panel 11. Rotating legs 19 are rotatably provided inside the mounting seats 18. One end of the rotating legs 19 has a threaded hole. A threaded rod 20 is fitted in each threaded hole. The threaded rod 20 is fixedly provided at one end of the seat leg 21. The bottom end of the seat panel 11 has a limiting mechanism for limiting the working position of the rotating legs 19. The limiting mechanism facilitates the limiting and fixing of the working position of the rotating legs 19, making it easy to use the rotating legs 19.
[0028] The fixing assembly includes a limiting rod 16. Each hinge seat 14 has a slidably mounted limiting rod 16 inside. Each limiting rod 16 is fixedly mounted on a push rod 15. The hinge seat 14 has a first limiting groove inside. Each hinge rod 13 has a second limiting groove corresponding to one end of a limiting rod 16 inside. A first return spring 17 is provided between one end of the push rod 15 and one end of the hinge rod 13 inside. A limiting plate is fixedly mounted on the other end of the push rod 15. The hinge rod 13 has a first return spring 17 between its inner and outer ends. The seat back 12 is provided with a stop groove at the corresponding position of the seat plate. When it is necessary to fold or unfold the seat back 12, push the push rod 15. The push rod 15 drives the two limit rods 16 to slide, so that the limit rods 16 slide into the second limit groove, and then the seat back 12 is folded or unfolded. After folding or unfolding is completed, release the push rod 15. Under the action of the first return spring 17, the limit rods 16 slide back into the first limit groove, thereby fixing the seat back 12.
[0029] The limiting mechanism includes a limiting block 23. Each of the rotating legs 19 has a fixed groove at one end, and the limiting block 23 is slidably disposed within each fixed groove. The limiting block 23 is slidably disposed within a sliding hole on one side of the mounting base 18. The limiting block 23 is fixedly disposed at one end of the pull rod 24. A fixed tube is slidably disposed on the pull rod 24, and each fixed tube is fixedly disposed at the bottom end of the seat plate 11. A sliding plate is fixedly disposed on the pull rod 24, and the sliding plate is slidably disposed inside the fixed tube. A second return spring 25 is fixedly disposed between one side of the sliding plate and one side of the fixed tube. A fixed shaft is fixedly disposed on the rotating shaft at one end of the rotating leg 19. A torsion spring 22 is disposed between one end of the fixed shaft and one side of the mounting base 18. In use, when… When the chair needs to be disassembled, rotate the chair leg 21. The chair leg 21 drives the threaded rod 20 to rotate, thus removing the chair leg 21. Then pull the lever 24. The lever 24 drives the limiting block 23 to slide. The limiting block 23 disengages from the fixing groove. Under the action of the torsion spring 22, the rotating support leg 19 is folded and stored. When the chair needs to be installed, rotate the rotating support leg 19. When one side of the rotating support leg 19 is in close contact with the inside of the mounting base 18, under the action of the second return spring 25, the lever 24 pushes the limiting block 23 to re-insert into the fixing groove, thereby fixing the rotating support leg 19. Then install the chair leg 21 on one end of the rotating support leg 19, thus completing the installation of the chair.
[0030] The rotating support leg 19 is internally equipped with a stop rod 26. A third return spring 27 is provided between one end of the stop rod 26 and the interior of the rotating support leg 19. The bottom end of the limiting block 23 is provided with an anti-detachment groove corresponding to one end of the stop rod 26. One end of the stop rod 26 is tightly attached to one end of the threaded rod 20. In use, after the rotating support leg 19 is unfolded and fixed by the limiting block 23, the threaded rod 20 is installed on one end of the rotating support leg 19. During the installation process, the threaded rod 20 is tightly attached to one end of the stop rod 26, and the threaded rod 20 pushes the stop rod 26 to slide. When one end of the seat leg 21 is tightly attached to one end of the rotating support leg 19, one end of the stop rod 26 is inserted into the anti-detachment groove, thereby fixing the limiting block 23 and preventing the limiting block 23 from detaching from the fixing groove during use.
[0031] Each seat leg 21 is fixedly provided with a second limiting slide rod 29 at one end. A first limiting slide rod 28 is fixedly provided at one end of the rotating support leg 19 at a position corresponding to the second limiting slide rod 29. Both the first limiting slide rod 28 and the second limiting slide rod 29 have T-shaped cross-sections. A limiting plate 30 is slidably provided on the first limiting slide rod 28. Arc-shaped rods are fixed on both sides of the limiting plate 30. A fixing ring 31 is provided at one end of the rotating support leg 19 at a position corresponding to the arc-shaped rod. In use, after the seat leg 21 is installed at one end of the rotating support leg 19, the second limiting slide rod 29 and the first limiting slide rod 28 are aligned. Then, under the action of gravity, the limiting plate 30 slides on the first limiting slide rod 28, causing the second limiting slide rod 29 to insert into the limiting plate 30, thereby limiting the position of the seat leg 21 and preventing it from rotating during use.
[0032] Example 2
[0033] The difference from Embodiment 1 is that: a storage bag 32 is installed on one side of the seat back 12, and a closing curtain 33 is provided at the upper end of the storage bag 32. Both the storage bag 32 and the closing curtain 33 are made of flexible fabric. The storage bag 32 is symmetrically provided with a first fixing strap, and the closing curtain 33 is provided with a second fixing strap at the position corresponding to the first fixing strap. When the furniture chair needs to be disassembled, the seat legs 21 are removed, so that the seat back 12 and the rotating support leg 19 can be rotated and folded for storage. Then, several seat legs 21 are placed inside the storage bag 32 for storage. The first fixing strap and the second fixing strap seal one end of the storage bag 32, thereby preventing the seat legs 21 inside the storage bag 32 from falling out.
[0034] The above embodiment discloses a furniture chair that is easy to assemble and disassemble. When the seat back 12 needs to be unfolded, the push rod 15 is pushed, causing the two limiting rods 16 to slide into the second limiting groove. This allows the seat back 12 to be either folded or unfolded. After unfolding, the push rod 15 is released, and under the action of the first return spring 17, the limiting rods 16 slide back into the first limiting groove, thus fixing the seat back 12. Then, the rotating support leg 19 is rotated. When one side of the rotating support leg 19 is in close contact with the inside of the mounting base 18, under the action of the second return spring 25, the pull rod 24 pushes the limiting block 23 back into the fixing groove, thus fixing the rotating support leg 19. The screw... The threaded rod 20 is installed at one end of the rotating support leg 19. During the installation process, the threaded rod 20 is in close contact with one end of the stop slide rod 26, and the threaded rod 20 pushes the stop slide rod 26 to slide. When one end of the seat leg 21 is in close contact with one end of the rotating support leg 19, one end of the stop slide rod 26 is inserted into the anti-disengagement groove, thereby fixing the limiting block 23 and preventing the limiting block 23 from disengaging from the fixing groove during use. At the same time, the second limiting slide rod 29 is in the same straight line as the first limiting slide rod 28. Then, under the action of gravity, the limiting plate 30 slides on the first limiting slide rod 28, so that the second limiting slide rod 29 is inserted into the limiting plate 30, thereby limiting the position of the seat leg 21, thus completing the installation of the seat.
[0035] When the chair needs to be disassembled, push the push rod 15. Push rod 15 drives the two limit rods 16 to slide, so that the limit rods 16 slide into the second limit groove. Then, the seat back 12 rotates 90 degrees and the seat back 12 is in close contact with the upper end of the seat plate 11. Release push rod 15. Under the action of the first return spring 17, the limit rods 16 slide back into the first limit groove, thereby fixing the seat back 12. Rotate the seat leg 21. The seat leg 21 drives the threaded rod 20 to rotate, thereby removing the seat leg 21. Then pull the pull rod 24. Pull rod 24 drives the limit block 23 to slide. The limit block 23 disengages from the fixing groove. Under the action of torsion spring 22, the rotating support leg 19 is folded and stored. Several seat legs 21 are placed in the storage bag 32 for storage. The first fixing strap and the second fixing strap seal one end of the storage bag 32, thereby preventing the seat legs 21 from falling out of the storage bag 32. It is highly practical.
[0036] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
