[0009] Working principle:

[0010] The display packaging box includes a bottom plate and four side plates. The four side plates are arranged opposite to each other in groups of two. One group of side plates forms a downwardly opening gap groove through the gap between the inner plate and the outer plate. The other group of side plates is provided with L-shaped positioning plates on both sides of the outer plate. One end of the L extends into the gap groove and cooperates with the gap groove. The positioning plates are restricted from detaching through the gap groove, thereby supporting the side plates. At the same time, supporting corner columns are provided on both sides of the inner plate of the group of side plates, that is, supporting columns are provided at the four corners of the box. When the entire box is expanded and deformed by internal and external stresses, the above structure greatly increases the pressure-bearing capacity of the box.
