Description

FIELD OF TECHNOLOGY The present disclosure relates to the technical field of chairs, in particular to a quick-assembly chair. BACKGROUND Chair assembly technology has been relatively mature, especially in the modern industrial production environment. Many chair manufacturers have adopted advanced production lines and automated equipment to ensure the accuracy and efficiency of chair assembly. These technologies not only increase production speed but also reduce the possibility of human error, thus boosting the overall quality of the chair. Due to the development of logistics and changes in people's living habits, chairs are no longer sold to consumers as fully assembled units but rather as multiple components for self-assembly. Therefore, the convenience of assembly of a chair is a very important aspect. Many chairs adopt a modular structure, making the assembly process easier and more efficient. Modular assembly allows manufacturers to break down the chair into multiple independent parts, which may be easily delivered and assembled. However, current rapid assembly methods for chairs primarily involve the localized use of snap-fit mechanisms combined with hand-tightened screws. These still present drawbacks such as cumbersome assembly, a large number of hand-tightened screws, a poor user experience, and insufficient structural strength. The above disclosure is only intended to assist in understanding the inventive concept and technical solution of the present disclosure, and it does not necessarily belong to the related art of the present patent application. In the absence of clear evidence that the above content has been disclosed on the filing date of the present patent application, the above disclosure should not be used to evaluate the novelty and creativity of the present application.
