Description

Technical Field

[0001] The utility model relates to the field of furniture, in particular to a disassembly and assembly combined wooden chair. Background Art

[0002] Furniture refers to a broad category of equipment and facilities essential for people to maintain normal life, engage in production practices, and carry out social activities. Furniture has continuously evolved and innovated with the times, and today encompasses a wide range of categories, materials, varieties, and uses. It is an essential foundation for creating work and living spaces. Furniture is composed of four factors: material, structure, appearance, and function. Function is the driving force behind furniture development, while structure is the backbone and the foundation for achieving function. These four factors are interconnected and mutually constrained. Because furniture is designed and manufactured to meet specific material needs and purposes, it also has material and appearance factors. A chair is a piece of seating with a backrest and, in some cases, armrests.

[0003] Currently, modular wooden chairs are generally fixed by mortise and tenon joints or screws. Since the mortise and tenon fixing structure requires precise assembly, the entire wooden chair is assembled in the factory, which is bulky, increasing the risk and complexity during transportation and increasing transportation costs. Although the screw fixing method can be installed by consumers themselves after purchase, the screw fixing method is poorly concealed, affecting the aesthetics. The screws will be exposed in certain parts of the modular wooden chair, destroying the overall beauty of the furniture. Therefore, further improvement is needed. Utility Model Content
