Description

Technical Field

[0001] The utility model relates to the technical field of furniture components, in particular to a modular sofa seat frame. Background Art

[0002] Modular furniture is composed of individual sofas. At present, most modular sofas sold on the market are fixed configurations, and individual sofas have their own fixed shapes. Users must purchase the whole set, which is not expandable. In addition, because individual sofas have their own specific shapes, modular packaging cannot be achieved, which increases packaging costs.

[0003] On March 9, 2016, a single package modular sofa was authorized for disclosure, and its authorization announcement number is CN205072502U. The utility model patent includes a seat frame, side panels and leg tubes, and the side panels and leg tubes are detachably connected to the seat frame, and the size of the side panels is smaller than the inner frame size of the seat frame. It has the following advantages: simple structure, convenient disassembly and assembly, when packaging, the side panels and leg tubes are removed, and the side panels and leg tubes are placed in the seat frame, so as to realize modular packaging and optimize the single-unit packaging. When installing, the number of side panels can be selected according to needs. If no side panels are installed, it can be used as a seat and a coffee table; if one side panel, two side panels and three side panels are installed, it can be used as a single sofa, a corner sofa, or a double-armrest sofa. It can be freely combined and freely selected for configuration, which is convenient for future expansion at any time.

[0004] However, the modular sofas in the prior art have the following defects;

[0005] 1. In the prior art, a spring assembly is usually required to be installed on the seat frame. When installing the spring assembly, one end of the spring assembly is usually connected to a beam on one side of the seat frame, and then the spring assembly is tightened to make the spring assembly stretch and become taut. Only then can the other end of the spring assembly be connected to the beam on the other side of the seat frame. The installation method is laborious; and after the spring assembly is installed, its tightness cannot be adjusted within a certain range.

[0006] 2. In the prior art, the seat frame cannot be disassembled and assembled, and takes up space during transportation, thereby increasing the packaging and transportation costs. Utility Model Content
