Description

Technical Field

[0001] This utility model belongs to the technical field of furniture, and in particular relates to a seat frame mounting structure and a sofa containing the structure. Background Technology

[0002] A sofa is a piece of furniture for resting, commonly used in living rooms, reception rooms, and other similar spaces. A sectional sofa is constructed by joining the seat frame, backrest, and armrests using various connecting structures. Chinese Patent Publication No. CN221997416U discloses a sofa seat frame and its supporting skeleton. Specifically, it discloses the sofa seat frame body, which has multiple T-shaped slots on all four sides. T-shaped blocks are movably embedded in each of these slots. The T-shaped blocks are divided into two groups, and elastic elements are fixedly connected to the opposite faces of the two groups of T-shaped blocks. The two groups of T-shaped blocks are embedded into the T-shaped slots, causing the elastic elements to intersect, thus increasing their load-bearing capacity. Multiple limiting plates are then embedded into limiting grooves on the outer surfaces of the four sides of the sofa seat frame body, fitting against the upper ends of the T-shaped blocks to limit and fix them. Multiple bolts are threaded into the mounting holes and limiting holes, fixing the limiting plates inside the limiting grooves. This prevents the T-shaped blocks from falling out of the T-shaped slots. However, this sofa seat frame has a complex structure and is relatively cumbersome to assemble and disassemble with other sofa accessories. Utility Model Content
