Description

Technical Field

[0001] This utility model relates to the field of furniture equipment technology, and more specifically, to a sofa connection structure that is easy to disassemble. Background Technology

[0002] As the home furnishing market continues to upgrade, consumers' demands for sofas are no longer limited to comfort and aesthetics; they also increasingly require convenience and flexibility. Therefore, the ease of disassembly and assembly is particularly important during the transportation, installation, storage, and maintenance of sofas.

[0003] Traditional sofas mostly use permanent or semi-permanent connection methods such as welding and bolting. Welding makes the sofa parts form a whole, and it is almost impossible to separate them without damage when disassembly is needed, which greatly limits the sofa's movement and spatial adjustment. While bolting can theoretically be disassembled, in practice, it often requires multiple tools and involves a large number of bolts. The disassembly and assembly process is cumbersome, time-consuming, and labor-intensive, making it difficult for ordinary consumers to complete independently. For consumers who frequently change their living environment or seek flexibility in home layout, sofas that cannot be quickly disassembled and reassembled cannot meet their needs for space utilization and home style changes.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content
