Patent attributes
A connector for shelf assembly may comprise at least a connector having a semi-cylindrical concave formed at a lateral edge thereof, and a first hook portion and a second hook portion respectively protrude from two lateral ends of the inner edge of the concave. When the connector is applied to a shelf, the first hook portion and the second hook portion thereof are configured to respectively hook on two adjacent edges of a shelf board of the shelf which are perpendicular to each other. Each of the connectors can be directly coupled with a collar of the shelf board such that an external board can be assembled between the two shelves without dissembling process. Also, the external board can be assembled parallel with the shelf boards on the two shelves, which improves the practicability and stability of the assembled shelves with the external board when in use.
