[0125] The structural support member 140 comprises an upright brace 141 arranged between the first upright 131 and the second upright 132. The structural support member 140 is used to reinforce the lateral support member 120 and the vertical support member 130.

[0126] Shelving devices, such as shelves, are usually presented in the form of parts during transportation and sale. After the relevant products are purchased by consumers, they need to be assembled into finished products by themselves. At present, the fixing of the upright and the upright brace needs at least two people to cooperate during the assembly process, or the upright is laid horizontally on the ground for assembly. This assembly method is not convenient for ordinary consumers.

[0127] The present application provides a positioning mechanism 150 arranged at one end of the upright brace 141. The positioning mechanism 150 can position one end of the upright brace 141 at a predetermined position of the first upright 131, so as to ensure that the first upright 131 and the upright brace 141 can be accurately assembled and positioned. In this way, the assembly personnel can not need to hold with both hands, which improves the work efficiency and simplifies the operation process, and is easy to implement.

[0128] Referring to FIGS. 1-7, in one embodiment, a shelving device 100 comprises a shelving member 110, a lateral support member 120, a vertical support member 130, and a structural support member 140.

[0129] The shelving device 100 is a frame structure as a whole, which is formed by the lateral support member 120 and the vertical support member 130. “Longitudinal” refers to the length direction of the frame structure shown by the arrow X in FIG. 1, “lateral” refers to the width direction of the frame structure shown by the arrow Y in FIG. 1, “vertical” refers to the height direction of the frame structure shown by the arrow Z in FIG. 1, “upward” refers to the direction consistent with the arrow Z in FIG. 1, and “downward” refers to the direction opposite to the arrow Z in FIG. 1.

[0130] The shelving member 110 can be one layer or multiple layers, which is used to store articles.

[0131] The shelf member 110 can be a shelf or a wire mesh shelf. The shelf is a plate-shaped object made of metal or plastic, etc., and has the advantage that the objects stored thereon are not easily dropped. The wire mesh shelf is a mesh object composed of a plurality of longitudinal wires and a plurality of transverse wires, and has the advantages of light weight and material saving. Preferably, the longitudinal wires and the transverse wires are metal wires. The wire mesh shelf is welded by a plurality of longitudinal wires and a plurality of transverse wires.

[0132] Correspondingly, the transverse support member 120 can be one or more layers for supporting the shelf member 110. The transverse support member 120 can include a first cross beam 121 and a second cross beam 122 arranged transversely opposite to each other. The first cross beam 121 and the second cross beam 122 have support surfaces for supporting the shelf member 110. The support surfaces of the first cross beam 121 and the second cross beam 122 are located in the same plane for supporting one layer of the shelf member 110.

[0133] The vertical support member 130 is used to support the cross beam 121. The vertical support member 130 can include a first upright column 131 and a second upright column 132 arranged transversely opposite to each other.

[0134] The structural support member 140 includes a column brace 141 arranged between the first upright column 131 and the second upright column 132. The column brace 141 can include a horizontal brace 142 and an inclined brace 143. The horizontal brace 142 is arranged horizontally between the first upright column 131 and the second upright column 132. The inclined brace 143 is arranged obliquely between the first upright column 131 and the second upright column 132, for example, one end of the inclined brace 143 is arranged at the lower end of the first upright column 131, and the other end of the inclined brace 143 is arranged at the upper end of the second upright column 132. The column brace 141 can enhance the stability of the first upright column 131 and the second upright column 132.

[0135] Further, the structural support member 140 further includes a cross beam brace 144 arranged between the first cross beam 121 and the second cross beam 122. The cross beam brace 144 can enhance the stability of the first cross beam 121 and the second cross beam 122.

[0136] One end of the column brace 141 is provided with a positioning mechanism 150, which can position one end of the column brace 141 at a predetermined position of the first upright column 131, ensuring that the first upright column 131 and the column brace 141 can be accurately assembled and positioned. In this way, the assembler can not need to hold with both hands, improving work efficiency, and the operation process is simple and easy to implement.
