Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0021] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Combined with appendix Figures 1 to 5As shown, this embodiment discloses a chair with a detachable seat frame support structure, including an upper seat frame 1, several support components 2, a lower seat frame 3, two armrest frames 4, and a backrest frame 5. The upper seat frame 1, lower seat frame 3, armrest frames 4, and backrest frame 5 are detachably connected. The support components 2 are used to fix the upper seat frame 1 and lower seat frame 3 together. The support components 2 include a support cover 21 and a support column 22. The support cover 21 and the support column 22 are connected by threads. In other embodiments, other common connection methods such as embedded connection or snap-fit ​​connection can also be used. Several upper positioning seats 11 are provided on the inner side of the upper seat frame 1, and several lower positioning seats 31 are provided on the inner side of the lower seat frame 3. The positions of the upper positioning seats 11 and the lower positioning seats 31 correspond to each other, and their number is the same as that of the support components 2. The upper and lower ends of the support components 2 are detachably inserted into the upper positioning seats 11 and the lower positioning seats 31, respectively.

[0023] In conjunction with the above, it also includes a seat surface 6, which is made of flexible material to improve user comfort and facilitate flat unfolding. The upper seat frame 1, support component 2, and lower seat frame 3 are located inside the seat surface 6. The seat surface 6 also includes an elastic cord (not shown in the figure). After the support component 2 is assembled, the elastic cord is tightened to allow the upper seat frame 1, support component 2, and lower seat frame 3 to unfold the seat surface 6.

[0024] In combination with the above, the handrail frame 4 includes a handrail side frame 41, a handrail connecting frame 42, and a handrail base frame 43. The inner side of the handrail connecting frame 42 is detachably connected to the outer sides of the upper seat frame 1 via screws or other connecting parts. The inner side of the handrail base frame 43 is detachably connected to the outer sides of the lower seat frame 3 via screws or other connecting parts.

[0025] In combination with the above, the backrest frame 5 includes a backrest side frame 51, a backrest connecting frame 52, and a backrest base frame 53. The inner side of the backrest connecting frame 52 is detachably connected to the outer rear side of the upper seat frame 1 by screws or other connecting parts. The inner side of the backrest base frame 53 is detachably connected to the outer rear side of the lower seat frame 3 by screws or other connecting parts.

[0026] Combined with the above installation structure, the armrest side frame 41 and the backrest side frame 51 are detachably connected by fasteners, realizing a detachable connection between the external frames of the chair.

[0027] With the above installation structure, when the seat frame of the chair needs to be disassembled, simply tighten the support component 2 to remove it from the upper positioning seat 11 and the lower positioning seat 31. Then the seat 6 loses its support, and the seat 6 can be stacked flatly with the upper seat frame 1 and the lower seat frame 3, saving space and transportation costs. At the same time, the disassembly and assembly process is simple and convenient, saving time and effort.

[0028] In addition to the above, a backrest cushion 7 is also provided on the seat 6 to improve user comfort.
