Coupling plate frame

Abstract

A coupling plate frame is integrally made of hardened high molecular material and comprises a top plate section a vertical plate section, a bottom plate section, and two flap plates. The top plate section has an engaging hole thereon. The vertical plate section is integrally associated with the top plate with a width gradually reduced from a top to a bottom thereof, and has an engaging hole near the bottom thereof. The bottom plate section is attached integrally to the vertical plate section with extending outward and opposite to the top plate section from the vertical section plate. Each of the flap plates is integrally attached to the top plate section, the vertical plate section, and the bottom plate section, respectively. Each flap plate is slant at the top plate section and extends downward along the vertical plate, and the width between the flap plates is gradually smaller from a top thereof to a bottom thereof. Two of the coupling plates can be lapped to each other without occupying extra space.
