Abstract: A combination shelf structure has a design of combining storage partition layers and support rods of a combination shelf. The support rods are installed at a right angle with the storage partition layers, and two support rods are installed into two upper and lower insert slots with an interval apart from one another. Upper and lower embedding plates are formed on both sides of each corner position of a frame of the storage partition layer respectively by a hollow stamping process, such that the embedding plate and the frame are situated on the same plane, and the storage partition layer can be combined securely and easily by using the embedding plate of the frame and the insert slot of the support rod. In addition, the storage partitions and the insert slots of the support rod can be rearranged with appropriate installation elements to achieve a different shape of the shelf.
