Abstract: A hook connection structure of a shelf is configured to connect a fixing rod between two hooks which are connected on two bottoms of two connection racks, and the fixing rod is mounted below a holding plate by using the two hooks. The hook connection structure contains: a respective one hook including a connection portion which has an extension, an engagement section, a contact rib, and a stop tab. A respective one of two connection racks includes a slot formed on an elongated portion of the respective one connection rack, a notch defined on the slot, such that the stop tab of the extension of the respective hook abuts against the elongated portion of the respective one rack, the respective one hook is connected on a bottom of the respective one connection rack, and the fixing rod is mounted below the holding plate to hang objects.

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.

Abstract: The present invention relates to an improved rack fixture structure, and more particularly to a design of a rack having a support rod, a longitudinal groove, an inserting groove, and a plurality of pairs of insert slots on both lateral positions to go with an insert end of a partition bracket, an embedding guide portion, a latching plate and an inserting latch plate, such that the partition bracket can be displaced and adjusted appropriately under the guidance of the longitudinal groove, and simple embedding, latching and positioning effects can be achieved, so as to increase or decrease the quantity of partition brackets and provide a simple and easy way of making interval adjustments.
