Size-adjustable storage box and bidirectional collapsible assembly plate

Abstract

A resizable storage box includes a box body with an accommodating space formed by a side wall (1) and at least one bottom plate (3) that are connected, where the side wall includes four bidirectional retractable plate assemblies (1-1); each of the bidirectional retractable plate assemblies (1-1) includes a first lateral corrugated plate (1-11) and a second lateral corrugated plate (1-12) that are in a slidable sleeve connection; and respective retraction and extension directions of the first lateral corrugated plate (1-11) and the second lateral corrugated plate (1-12) are perpendicular to a sliding direction of the first lateral corrugated plate (1-11) relative to the second lateral corrugated plate (1-12). A bidirectional retractable plate assembly for the storage box includes a first lateral corrugated plate (1-11) and a second lateral corrugated plate (1-12) that are in a slidable sleeve connection. The storage box can be adjusted in size in three directions, can be retracted and extended to be folded, and can also adapt to the packaging or storage of items of different sizes through self-adjustment.
