Abstract
A shelf positioning mechanism for sectional rack constructed particularly from vertical posts having spaced horizontal annular grooves and horizontal shelves mainly includes a positioning member fitted between a short sleeve provided at each corner of the shelf and a connecting member configured to attach to the vertical post at the annular groove. The positioning member has downward and outward inclined inner wall surface that applies a clamping force on a downward and outward inclined outer wall surface of the connecting member for the latter to securely attach to the vertical post, and has a straight outer wall surface to tightly bear against a straight inner wall surface of the short sleeve for the shelf to be selectively turned upside down when it is assembled to the vertical posts.
