Abstract
sofa assembly comprising a sofa backrest connection structure (1), a sofa seat frame (2), and a sofa backrest (3). The connection structure includes a first member (11) and a second member (12), wherein the first member includes a first base plate (111), two guide rails (112) symmetrically arranged on the first base plate, and a limiting part (113) arranged on the first base plate, and the limiting part is provided with a clamping protrusion (1132). The second member includes a second base plate (121) and a first horizontal plate (122) connected to the second base plate, the second base plate includes an insertion part (1211), and the insertion part is provided with a clamping hole (12111) matched with the clamping protrusion. After the insertion part is slidably inserted into and fitted with the two guide rails, the clamping protrusion is clamped in the clamping hole, and the second base plate and the first horizontal plate are integrally bent and formed. The sofa seat frame comprises two symmetrically arranged cross beams (21) and two longitudinal beams (22) connected with the two cross beams; the first horizontal plate is connected with upper surfaces of the two longitudinal beams; and the first base plate is connected with the sofa backrest. The connection structure, the sofa backrest, and a sofa main body can be firmly connected, and assembly and disassembly of the sofa backrest are more convenient, so that the assembly and disassembly efficiency of the sofa assembly is improved.
