Shelf

Abstract

This invention provides a shelf with simple structures. It can be easily assembled and disassembled. The shelf includes a stand column, a main frame, a side frame and a metal bracket. The main frame and the side frame are connected to the stand column by metal bracket to make a shelf with two tiers or more. The stand column is connected to the metal bracket along with a setup of convex circle for the fixation. The shelf of this invention is firm and steady, easy to assemble and disassemble with high loading capacity. The shelf serves as a storage device with simple structure; moreover it is convenient for the transport, thus can be widely used in office supplies.
