[0023] FIG. 1 is a perspective view of one embodiment of a storage rack that allows for tool-free assembly of a cabinet of the present invention. FIG. 2 is a perspective view of a cross member according to FIG. 1 of the present invention. FIG. 3A is an explanatory diagram of the cross member and square tube member of the present invention before assembly. FIG. 3B is an explanatory diagram of the cross member attached to the square tube member of the present invention. Referring to FIGS. 1 to 3B, a storage rack 100 that allows for tool-free assembly of a cabinet of the present invention includes a group of support columns 110, at least one cross member 120, at least one horizontal layer 130, at least one vertical layer 140, an assembly device 150, and a rear plate 160.

[0024] The column group 110 includes four rectangular tube members 112, each of which is made up of four plates forming a rectangular structure. The rectangular tube members 112 are hollow and may be, for example, iron pipes. Two of the rectangular tube members 112 are spaced apart along a first direction L1, and two of the rectangular tube members 112 are spaced apart along a second direction L2. An assembly hole 114 is provided on one surface of the rectangular tube member 112 (see FIGS. 3A and 3B), and the assembly hole 114 has a shape that is wide at the top and narrow at the bottom.

[0025] The cross member 120 is arranged between these square tube members 112, and includes two first plates 122, two second plates 123, and four engaging structures 124. The two first plates 122 are spaced apart along the second direction L2 to form the front and rear structures of the cross member 120, and the two second plates 123 are spaced apart along the first direction L1 to form the left and right structures of the cross member 120.
