The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0035] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying 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.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0037] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] like Figures 1-12 The chair shown is easy to assemble and disassemble, including two side support frames 1 and a chair frame that can be detachably mounted on the two side support frames 1. The two side support frames 1 are fitted with frames on both sides of the chair frame. The upper end of the chair frame is higher than the upper end of the support frame 1, and the lower end of the chair frame is higher than the lower end of the support frame 1.

[0040] In the above technical solution, the easy-to-assemble and disassemble chair includes two side support frames and a chair frame. The two side support frames are used to support the chair frame, eliminating the need for legs and providing more reliable support for the chair frame. The chair frame and the two side support frames are detachable, so the chair can be disassembled into multiple parts, which is convenient for disassembly and assembly, handling and transportation, and reduces handling difficulty and transportation costs.

[0041] Furthermore, L-shaped connecting pieces 2 are provided on both sides of the inner wall of the support frame 1, and the chair frame is mounted on multiple L-shaped connecting pieces 2; the L-shaped connecting pieces 2 and the support frame 1 are respectively provided with first connecting holes 3; the L-shaped connecting pieces 2 and the chair frame are respectively provided with second connecting holes 4. In this technical solution, L-shaped connecting pieces are provided on both sides of the inner wall of the support frame, and bolts or pins are inserted into the first connecting holes of the L-shaped connecting pieces and the support frame to fix them together. When installing the support frame and the chair frame, the chair frame is mounted on four L-shaped connecting pieces, and bolts or pins are then inserted into the second connecting holes corresponding to the L-shaped connecting pieces to connect the support frame and the chair frame, making assembly and disassembly very convenient.

[0042] like Figures 7-12 As shown, the chair frame includes an iron frame 100; the iron frame includes a seat frame 1001 and a surrounding frame 1002 welded to the seat frame. A front beam 1003 is welded to the front side of the surrounding frame above the seat frame. Multiple first vertical bars 5 are welded between the surrounding frame and the seat frame. A rear beam 1004 corresponding to the front beam is welded between the two opposite first vertical bars 5 on the rear side of the surrounding frame. A short pipe 20 is welded between the upper end of the rear beam and the first vertical bar 5 located behind it. First short bars 6 are welded between the two sides of the rear beam and the seat frame.

[0043] The above is a single-seat bench design. The iron frame and the side support frames are detachable. Both the iron frame and the support frames are made of iron parts using processes such as laser cutting, CNC bending, and welding. Compared with wood, the iron frame has higher processing precision and is easier to process, which can improve production efficiency. At the same time, the overall structural strength is higher, and it can withstand greater weight without deformation. Specifically, multiple first vertical bars can improve the connection strength between the bench frame and the seat frame, the rear beam, the front beam, and the short tube can improve the internal structural strength of the bench frame, and the first short bar can improve the connection strength between the bench frame and the seat frame.

[0044] Furthermore, the upper end of the rear beam 1004 is lower than the lower end of the front beam 1003, and a first spring assembly 7 is inclined between the rear beam and the front beam. In this technical solution, the first spring assembly is inclined to prevent the user from leaning forward when sitting, and the effect of the front being higher than the back makes sitting more comfortable.

[0045] Furthermore, a fabric fixing tube 8 is horizontally welded between the short tube 20 and its upper end and the front beam. In this technical solution, the fabric fixing tube not only improves the structural strength of the frame, but also makes the fabric smoother and more aesthetically pleasing after being fixed to it.

[0046] Furthermore, the two side support frames 1 surround the outer side of the chair frame. The support frame 1 is an arc-shaped frame, and a connecting block 9 is detachably provided between the two side support frames 1 below the L-shaped connecting piece 2. In this technical solution, the arc-shaped support frame not only adapts to the shape of the two sides of the chair frame, but also greatly increases the contact area with the ground, providing better support than legs. In addition, the connecting block can connect the two side support frames together, improving the connection stability of the two side support frames.

[0047] like Figures 1-6 As shown, the chair frame includes two iron frame side frames 200 and an iron frame middle frame 300 that is detachably disposed between the two iron frame side frames 200.

[0048] The iron frame side frame 200 includes a side seat frame 2001 and a side enclosure frame 2002 welded to the side seat frame. A first vertical beam 10 is welded to the upper front side of the side seat frame. A side front beam 2003 is welded between the first vertical beam 10 and the side enclosure frame. A second vertical rod 11 is welded between the side enclosure frame and the side seat frame. A side rear beam 2004 corresponding to the side front beam is welded to the second vertical rod 11. A second short rod 12 is welded between the lower two sides of the side rear beam and the side seat frame.

[0049] The iron frame 300 includes a middle seat frame 3001 and a back frame 13 located behind the middle seat frame. The back frame 13 is detachably connected to the side frames on both sides. Multiple second vertical beams 14 are welded to the upper periphery of the middle seat frame. A front beam 3002 and a rear beam 3003 are welded between the second vertical beams 14 on the front and rear sides of the middle seat frame, respectively.

[0050] The above is a multi-seat bench design. The bench frame and support frame are detachable, and the bench frame can be disassembled into three frames and a back frame, which can greatly reduce the packaging volume, facilitate handling and transportation, and reduce handling and transportation costs. The side frames, middle frames, support frames, and back frames are all made of iron parts using laser cutting, CNC bending, and welding processes. Compared with wood, iron frames have higher processing precision and are easier to process, which can improve production efficiency. At the same time, the overall structural strength is higher, and it can withstand greater weight without deformation. Specifically, the second vertical bar can improve the connection strength between the side frame and the side seat frame, and the second short bar can improve the connection strength inside the side seat frame.

[0051] The middle frame and side frame are provided with corresponding first bolt holes 15, and the back frame 13 and side frame are provided with corresponding second bolt holes 16. The corresponding first bolt holes on the middle frame and side frame can be used to install bolts or pins to fix the side frame and middle frame, and the second bolt holes on the back frame and side frame can be used to install bolts or pins to fix the side frame and back frame, making disassembly and assembly convenient.

[0052] Furthermore, the upper ends of the side rear beam and the middle rear beam are lower than the lower ends of the side front beam and the middle front beam, respectively. A second side spring assembly 17 is obliquely arranged between the side rear beam and the side front beam, and a third side spring assembly 18 is obliquely arranged between the middle rear beam and the middle front beam. In this technical solution, the second and third spring assemblies are obliquely arranged to prevent the user from leaning forward when sitting, and the front-high-back-low effect makes sitting more comfortable. It should be noted that the absence of fabric fixing tubes here facilitates the disassembly of the entire chair frame.

[0053] Furthermore, inclined beams 19 are welded between the side rear beam and the side front beam and the side seat frame, and between the middle rear beam and the middle front beam and the middle seat frame. In this technical solution, the setting of the inclined beams makes the structure of the side seat frame and the middle seat frame more stable, further improving the structural strength of the chair and ensuring the stability of each component during transportation.

[0054] In this specific embodiment, addressing the inconvenience of transporting and handling existing chairs, especially multi-seat chairs, due to their difficulty in disassembly and assembly, as well as the problems of cumbersome processing and environmental unfriendliness associated with wooden chairs, the above solution divides the chair into two side support frames and a chair frame that can be detached from the support frames. For multi-seat chair frames, they can be further disassembled into multiple frames, facilitating transportation, storage, and assembly, reducing handling difficulty and transportation costs. If a part of the chair is damaged, the user can replace that part individually without replacing the entire chair, reducing maintenance costs. Furthermore, the support frames and frames are made of iron frames that have been cut, bent, and welded, resulting in high processing precision and ease of processing, improving production efficiency. Simultaneously, the overall structural strength is higher, capable of withstanding greater weight without deformation. Moreover, the entire chair frame, made of iron, is lighter and more environmentally friendly. It should also be noted that, as needed, a middle seat frame can be added to expand the chair into the required multi-seat configuration.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention.
