1. A storage box, comprising: a rectangular bottom plate, four side plates, a reinforcing ring and a top lid; wherein
the four side plates are arranged on a front edge, a rear edge, a left edge and a right edge of the rectangular bottom plate, and side edges of every two adjacent side plates of the four side plates are hinged with each other, so that the four side plates and the rectangular bottom plate jointly form an accommodating chamber with a top opening; a side plate of the four side plates on the left edge and a side plate of the four side plates on the right edge are configured to be folded front and rear or unfolded front and rear to form a vertical flat surface; the side plate on the left edge and the side plate on the right edge are folded to drive a side plate of the four side plates on the front edge and a side plate of the four side plates on the rear edge close to each other, and unfolded to drive the side plate on the front edge and the side plate on the rear edge away from each other; a rear side of the rectangular bottom plate is hinged to the side plate on the rear edge, so that the rectangular bottom plate is flippable up and down along a plurality of hinges; the rectangular bottom plate is configured to open a bottom of the accommodating chamber when flipped up and configured to block the bottom of the accommodating chamber and abut against the side plate on the front edge when flipped down; when the rectangular bottom plate is flipped up and the side plate on the left edge and the side plate on the right edge drive the side plate on the front edge and the side plate on the rear edge close to each other, the storage box is in a folded state; when the side plate on the left edge and the side plate on the right edge are unfolded to drive the side plate on the front edge and the side plate on the rear edge away from each other and the rectangular bottom plate is flipped down to block the bottom of the accommodating chamber and abut against the side plate on the front edge, the storage box is in an unfolded state, and when the storage box is in the unfolded state, the four side plates and the rectangular bottom plate jointly form the accommodating chamber with the top opening;
a bottom of the reinforcing ring is recessed upwards to form an insertion slot, and when the storage box is in the unfolded state, tops of the four side plates are insertable into the insertion slot, so that the reinforcing ring limits the side plate on the left edge and the side plate on the right edge from being folded front and rear; and
the top lid covers a top of the reinforcing ring, thereby blocking the top opening of the accommodating chamber.
