Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, specifically a distribution box that is easy to assemble. Background Technology

[0002] Currently, to ensure structural stability and ease of installation of electrical components, most existing distribution boxes are manufactured using a welding process. They are pre-molded into a single, fixed shape at the factory, resulting in a large volume that occupies significant space during transportation and is difficult to handle. Furthermore, distribution boxes are often manufactured in the factory, transported to retailers' warehouses, purchased by power engineering companies, and then transported to customers requiring installation. This process frequently involves several transfers before final use, leading to high transportation costs and inconvenience during transport. If distribution boxes could be flat-packed at the factory, their volume could be reduced by approximately four-fifths. They could also be easily unfolded and installed into a usable box, making transportation more convenient, reducing costs, and improving usability during use. Summary of the Invention
