ABSTRACT:
A connecting structure for sectional rack includes a plurality of vertical posts, horizontal shelves, and connecting members. Each of the vertical posts is provided with at least one row of engaging holes, with which upper and lower hooks at an end of each connecting member are engaged. A pad is attached to each connecting member, so that a first side of the pad fitly bears against the vertical post. A second side of the pad opposite to the first side is a downward and outward inclined surface. Each of the horizontal shelves has an outer cover provided at each corner thereof for putting on the connecting member, so that an internal inclined surface of the outer cover pushes the inclined surface of the pad against the vertical post to enable a firm connection of the shelf, the connecting member, and the vertical post to one another.
