[0002] As an essential piece of furniture in the family, the quality of the sofa is very important. All similar products on the market are made of triangular wooden structures to manufacture sofas, such as Figure 3 , the disadvantage of the triangular wooden structure is that local stress on the product causes huge potential quality hazards and is prone to problems. Once the local stress is severe, it is extremely easy to cause deformation or even dropping of the horizontally placed triangular blocks, seriously affecting the quality of the sofa. Moreover, the internal structure at the bottom of the sofa is in a mess, with horizontal and vertical lines, numerous joints, and is extremely unsightly. Therefore, in view of the above problems, a sofa adopting a beam-column structure is proposed. Content of the Utility Model

[0013] The cross-section of the splicing plate is in a concave shape, which not only saves wood, but also the beam-columns can be located therein. The beam-columns are arranged vertically and located at the four corners of the chassis, which can serve the purpose of good fixed support.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] The chassis structure of the present device of the present utility model adopts vertical beams and columns arranged at the four corners of the splicing plate. The beam-columns serve the purpose of stably supporting the four corners of the splicing plate. Even if the stress is severe, there will be no deformation or detachment. The advantage of the beam-column structure is that the overall frame is not prone to problems under stress, and the structure appearance is horizontal and vertical, clean and clear at a glance.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1

[0022] Please refer to Figure 1 、 Figure 2 and Figure 3 The present utility model provides a technical solution:

[0023] A sofa adopting a beam-column structure includes sofa side plates 1, a backrest plate 2 and a chassis mechanism 3.

[0024] Both sides of the above-mentioned chassis mechanism 3 are fixedly connected to the sofa side plates 1, and a backrest plate 2 fixedly connected to the sofa side plates 1 is further provided above the above-mentioned chassis mechanism 3;

[0025] Sofa foot pads 4 arranged front and back are installed at the bottoms of the above-mentioned sofa side plates 1;

[0026] The above-mentioned chassis mechanism 3 includes splicing plates 301, grooves 302 and beam-columns 303. The number of the above-mentioned splicing plates 301 is four groups. The contact surfaces of adjacent above-mentioned splicing plates 301 are fixedly connected, and grooves 302 are opened on the inner sides of the splicing plates 301. Vertically arranged beam-columns 303 are installed at the contact parts of adjacent above-mentioned splicing plates 301, and the above-mentioned beam-columns 303 are arranged inside the grooves 302.

[0027] As an essential piece of furniture in the family, the quality of the sofa is very important. All similar products on the market use a triangular wooden structure to manufacture sofas such as Figure 3 . The disadvantage of the triangular wooden structure is that local stress on the product causes huge potential quality hazards and is prone to problems. Once the local stress is severe, it is extremely easy to cause deformation or even fall of the horizontally placed triangular blocks, seriously affecting the quality of the sofa. Moreover, the internal structure at the bottom of the sofa is horizontally and vertically arranged in a messy and disorderly manner, making it unbearable to look at and very unsightly. The chassis structure of this device uses vertically arranged beam-columns 303 provided at the four corners of the splicing plates 301. The beam-columns 303 serve the purpose of stably supporting the four corners of the splicing plates 301. Even if the stress is severe, there will be no deformation or detachment. The advantage of the beam-column 303 structure is that the overall framework is not prone to problems under stress, and the structure appearance is horizontal and vertical, clean and clear at a glance.

[0028] Embodiment 2

[0029] This embodiment is an improvement made to Embodiment 1. Please refer toFigure 2 , specifically, the cross-section of the above splicing plate 301 is concave-shaped.

[0030] The above beam-column 303 is arranged in a quadrangular prism shape.

[0031] The number of the above beam-columns 303 is four groups, and the beam-columns 303 are all located at the corners of the rectangular frame surrounded by the splicing plate 301.

[0032] The cross-section of the splicing plate 301 is concave-shaped, which not only saves wood, but also the beam-column 303 can be located inside its groove 302. The beam-column 303 is arranged vertically and is located at the four corners of the chassis, which can achieve a good purpose of fixing and supporting.

[0033] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
