STORAGE BOX

Description

FIELD OF THE DISCLOSURE

The present invention relates to the technical field of storage boxes, and in particular, to a storage box.

BACKGROUND OF THE DISCLOSURE

A storage box is a box body used to store various articles such as clothes, files, and toys. The storage box usually includes a hollow box body, a cover plate used to close the box body, and side buckles rotatably assembled on side faces of the box body. The storage box may be used separately, or a plurality of storage boxes may be stacked into a cabinet for use. The side buckles of some existing storage boxes are used to buckle the cover plate on the box body. When users stack a plurality of storage boxes up and down, the side buckles may only buckle the cover plate on the box body where the side buckles are located but cannot buckle upper and lower box bodies together, resulting in the storage boxes being easily collapsed due to the lack of a stable connection between the upper and lower box bodies during use. The side buckles of some other storage boxes are used to fasten upper and lower box bodies when the storage boxes are stacked for use. However, when the user removes the stacked storage boxes and uses a single storage box, the side buckles cannot match the cover plate on the box body, resulting in the articles in the storage box falling out easily when the user uses the single storage box because the cover plate cannot be closed.
