Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0024] like Figures 1-4 As shown, a chair with replaceable movable support and flattenable packaging includes a seat frame assembly and a seat surface assembly. The seat surface assembly is detachably mounted on the seat frame assembly. The seat surface assembly includes a seat frame 6 arranged opposite each other and a flexible seat surface 7 disposed between the two seat frames 6. The flexible seat surface 7 is fixedly connected to the seat frame 6 on both sides, and the seat frame 6 is connected to the seat frame assembly. An adjustable tensioning assembly 8 is disposed between the two seat frames 6. The tensioning assembly 8 includes a rotatable adjusting member. By rotating the adjusting member, the length of the tensioning assembly 8 is changed, thereby adjusting the tension of the seat frame 6 and the flexible seat surface 7. The seat frame assembly includes support leg frames 1 arranged opposite each other. The front frame tubes of the two support leg frames 1 are connected by a front horizontal tube 2, and the rear frame tubes are connected by a rear horizontal tube 3. The top frame tube is set as an armrest 4, and the bottom frame tube is set with pads 5.

[0025] In one specific embodiment, the support frame 1 is a trapezoidal frame, with the length of the top frame tube being shorter than the length of the bottom frame tube.

[0026] In this embodiment, a positioning sleeve 9 is provided in the middle of the front frame tube and the rear frame tube of the support frame 1. After being sleeved with the end of the front horizontal tube 2 or the rear horizontal tube 3, it is fixed with fastening screws. Specifically, threaded holes are provided at both ends of the front horizontal tube 2 and the rear horizontal tube 3, and fastening holes are provided on the positioning sleeve 9. After the two ends of the front horizontal tube 2 or the rear horizontal tube 3 are inserted into the positioning sleeve 9, the fastening screw passes through the fastening hole of the positioning sleeve 9 and is fastened with the threaded hole of the front horizontal tube 2 or the rear horizontal tube 3.

[0027] The adjusting component in this application is an adjusting rod 83. The tensioning assembly 8 also includes a connecting rod 81 with a threaded portion. The adjusting rod 83 has a thread that mates with the threaded portion. The threaded portion is a threaded rod 82 provided on the adjusting rod 83. One end of the threaded rod 82 is movably inserted into the connecting rod 81, and the other end is threaded into the adjusting rod 83. A pin is provided at the end of the adjusting rod 83, which is rotatably inserted into the mounting hole provided on the chair frame 6. The tension of the chair surface assembly is adjusted by adjusting the adjusting rod 83 and the threaded rod 82.

[0028] In this embodiment, the chair frame 6 includes an integrally formed backrest frame 61 and seat frame 62. A first connecting piece 10 is provided at the bottom of the seat frame 62, which is fixed to a second connecting piece 11 provided on the front cross tube 2 by fasteners. A tensioning assembly 8 is assembled with the backrest frame 61. The flexible seat surface 7 is also integrally formed, and its two sides are fixedly connected to the chair frame 6. A support rod 12 is provided at the junction of the backrest frame 61 and the seat frame 62, and both ends of the support rod 12 are inserted into mating holes provided on the chair frame 6. To ensure the stability of the seat frame assembly, a reinforcing tube 13 is also provided in the seat frame assembly. Both ends of the reinforcing tube 13 are fitted with positioning sleeves 9 provided on the upper part of the rear frame tube of the support leg frame 1.

[0029] During assembly, first insert one end of the threaded rod 82 into the connecting rod 81, then rotate the other end of the threaded rod 82 into the adjusting rod 83 (the adjusting rod 83 has an internal thread that mates with the threaded rod 82), and adjust the tension through the threaded engagement; finally, insert the pin at the other end of the adjusting rod 83 into the mounting hole on the chair frame 6. Rotate the adjusting rod 83 to control the engagement between the adjusting rod 83 and the threaded rod 82 (i.e., rotate in a direction away from the threaded rod 82) until it can support the length of the flexible chair surface 7, at which point the installation is successful. For disassembly, tighten the adjusting rod 83 and the threaded rod 82 (i.e., rotate in a direction closer to the threaded rod 82) to remove it from the flexible chair frame 8, or replace it with a connecting rod 81 of different lengths. After removing the tensioning assembly 8 and the support rod 12, the two chair frames 6 can be stacked for flat packaging.

[0030] This application uses the front horizontal tube 2, rear horizontal tube 3, and reinforcing tube 13 to fix the two side support frames 1, forming a stable support; the first connecting piece 10 and the second connecting piece 11 are fixed by fasteners (such as fastening screws and bolts), realizing the detachable assembly of the seat frame assembly and the seat surface assembly. In addition, by using the tensioning component 8, not only can the outward adjustment of the distance between the two side chair frames 6 be realized, but the tension adjustment of the flexible seat surface 7 located between the two side chair frames 6 can also be completed, avoiding the problem of collapse of the flexible seat surface 7 after assembly; after the chair is disassembled, it can be stacked to achieve the effect of flat packaging.

[0031] During installation, the flexible seat surface 7 is first unfolded using the tensioning component 8 and the support rod 12. Then, the front horizontal tube 2, the rear horizontal tube 3, and the reinforcing tube 13 are assembled with the chair frame 6. Finally, the seat frame assembly and the seat surface assembly are fixed by the first connecting piece 10 and the second connecting piece 11.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
