AI Technical Summary
Existing corrugated cardboard boxes are prone to deformation and collapse when loaded with heavy objects or stacked, due to uneven stress, which can damage the contents inside.
Fixing blocks are installed at the inner corners of the corrugated cardboard box, and a support structure is formed by vertical bars, horizontal bars and long bars. Triangular supports are formed by diagonal bars to enhance the box's resistance to deformation. At the same time, the support structure can be folded and stored through limiting components and inner groove design.
It improves the support strength and stability of corrugated cardboard boxes, reduces the possibility of box collapse due to heavy objects, and facilitates the loading and unloading of items.
