Combining structure for shelves

A combining structure for shelves, comprising:

• at least a plurality of bearing portion, in the shape of a transverse frame or plate, and the bearing portions are arranged one above the other with some space, so that a storage space is formed between the bearing portions;
• multiple connecting rods, integrally connected to the periphery of each bearing portion, and each connecting rod extends toward the storage space to form at least one joining end;
• multiple vertical supporting tubes, in the form of hollow tubes having a circumferential wall and two abutting ends, wherein, on the circumferential wall of each vertical supporting tube near the abutting end, at least one avoiding groove is provided;
• multiple tubular connectors, provided inside each vertical supporting tube;
• at least one eccentric socket slot, vertically formed on at least one unilateral position inside each tubular connector, and corresponding to the avoiding groove of the vertical supporting tube, so that the vertical supporting tube can sheathe the joining end of the connecting rod through the eccentric socket slot of the tubular connector, and through the avoiding groove, each vertical supporting tubes can avoid the bearing portion, so that the joining between the vertical supporting tubes can be more smooth, and the shelf has more sense of beauty and value.
