ABSTRACT:
A shelving unit includes a support frame and at least one support board detachably mounted on the support frame. The support frame includes a back board which has at least one support rail which is provided with at least one locking slot. The shelving unit further comprises at least one locking knob mounted on the support board and detachably locked in the locking slot of the back board. The support board can be mounted on and detached from the support frame. Thus, the user only needs to rotate the locking knob to lock the support board onto the back board or to unlock the support board from the back board, so that the support board is mounted on and detached from the back board easily and quickly without using tools and saving a considerable amount of time for a user.
