Abstract

A foldable shipping shelf comprises: a loading part, two supporting parts, continuous hinges, and at least two first and second limiting parts. Each supporting part is connected to the loading part through at least one continuous hinge, and the two supporting parts are respectively connected to two opposite sides of the loading part. The first limiting parts are respectively fixed to the supporting parts at a place near to the loading part and keep the loading part in position. The second limiting parts are respectively fixed to the loading part at a place near to the supporting parts and keep the supporting parts in position. The two supporting parts rotate through the continuous hinges, and the first and second limiting parts limit a range for rotating the two supporting parts.
