TECHNICAL FIELD The present disclosure relates to a storage shelf, and in particular to a concave square tube storage shelf. BACKGROUND Assembled shelves are shelves that can be assembled and used for storage, consisting of multiple independent components (such as storage layers and connectors). The design of assembled shelves usually emphasizes flexibility and scalability to meet the needs of home interiors, offices and other occasions. Traditionally, there is a distinction between circular columns (round tubes) and square columns (square tubes). If circular columns are used, they cannot be horizontally and horizontally assembled for effective expansion. Therefore, the use of square tubes seems to be favorable.

The storage layers respectively comprise a shelf and a plurality of fasteners, wherein the fasteners are provided on the shelf, wherein the fasteners are respectively engaged to the corresponding assembly notch to secure the storage layers between the post columns. The laminates are respectively disposed on the corresponding storage layer. In one embodiment, each of the concave plates comprises a concave portion, a first plate portion, and a second plate portion, and both sides of each of the concave portions are connected to the corresponding first plate portion and the second plate portion, each of the first plate portions is connected to the corresponding first plate, each of the second plate portions is connected to the corresponding second plate, both sides of each of the fastener bodies are connected to the corresponding first plate portion and the corresponding second plate portion respectively. In one embodiment, each of the convex-type fastened components is separated from the concave portion in the corresponding concave plate by a distance, and each of the convex-type fastened components is inclined outwardly at an inclination angle relative to the concave square tube. In one embodiment, two sides of each of the fastener bodies has a first block and a second block respectively, one of the assembly notches is formed between a top of each first block and the corresponding convex block, and another one of the assembly notches is formed between a top of each second block and the corresponding convex block. In one embodiment, the fasteners have an inclination plane. In one embodiment, the fasteners are two first fasteners and two second fasteners. In one embodiment, each of the storage layers comprises two first assembly components and two second assembly components, each of the first assembly components is a Z-shaped buckle structure, the first fasteners are fasteners of the Z-shaped fastener structure, each of the second assembly components is an L-shaped buckle structure, and each of the second fasteners is a fastener of the L-shaped buckle structure. Based on the foregoing, the concave square tube storage shelf of the present disclosure has a simple assembly structure and is relatively stable, thereby improving the overall using convenience.
