Shelving Unit Whose Backplane is in Quick and Easy Assembly

Abstract

A shelving unit includes a support frame and a backplane combined with the support frame. The backplane includes an upright support, a transverse connecting rack detachably combined with the upright support, a first connecting bracket secured on the upright support, a second connecting bracket secured on the connecting rack and detachably combined with the first connecting bracket, and a fastening pin extending through the first connecting bracket and the second connecting bracket to combine the first connecting bracket and the second connecting bracket together. Thus, the first connecting bracket and the second connecting bracket are combined together and detached from each other by the fastening pin, so that the upright support and the connecting rack are assembled or disassembled easily and quickly, thereby facilitating a user assembling or disassembling the backplane of the shelving unit without using tools and saving a considerable amount of time for a user.
