         5 . The frame, as recited in  claim 4 , wherein said retention wall is biased against an inner surface of said retention slot when said locking element is engaged with at said attachment slot. 
     
     
         6 . The frame, as recited in  claim 1 , wherein each of said post lockers further comprises a retention wall perpendicularly extended from said locker wall to slidably insert into said retention slot when said locking element is engaged with at said attachment slot, wherein two of said retention walls are spacedly extended along an edge of said locker wall to define a space between said two retention walls, wherein an end of said cross member is extended through said space to detachably couple at said retention slot. 
     
     
         7 . The frame, as recited in  claim 1 , wherein each of said attachment slots, having a keyhole configuration, has an enlarged upper slot portion and an elongated lower slot portion, such that said locking element is slidably passed through said upper slot portion and is downwardly slid to engage with said lower slot portion so as to detachably lock up said beam member with said vertical post. 
     
     
         8 . The frame, as recited in  claim 1 , wherein each of said beam members comprises a vertical beam wall, a top beam wall integrally and horizontally extended from a top edge of said vertical beam wall, and a recessed beam flange integrally extended from said top beam wall to define a platform supporting surface for supporting said shelf platform thereon. 
     
     
         9 . The frame, as recited in  claim 8 , wherein each of said extension wall of said post locker has a locker tail extended to fittingly fill a space underneath said top beam wall at an opposite side of said platform supporting surface. 
     
     
         10 . The frame, as recited in  claim 8 , wherein each of the post lockers further comprises an attachment wall perpendicularly extended from said extension wall, wherein said attachment wall is overlappedly attached to said vertical beam wall of said beam member. 
     
     
         11 . The frame, as recited in  claim 8 , wherein said recessed beam flange comprises a vertical flange wall downwardly extended said top beam wall and a U-shaped folded platform supporting wall integrally and horizontally extended from said vertical flange wall to define said platform supporting surface on said folded platform supporting wall. 
     
     
         12 . The frame, as recited in  claim 8 , wherein each of said beam members further comprises a reinforcing wall integrally extended and inwardly folded on said vertical beam wall at a bottom edge thereof to bias against said post locker. 
     
     
         13 . The frame, as recited in  claim 8 , wherein each of said beam members further comprises at least one longitudinal reinforcing rib integrally and outwardly extended from said vertical beam wall. 
     
     
         14 . The frame, as recited in  claim 1 , further comprising a plurality of reinforcing members, wherein each of said beam members has at least a longitudinal slot formed at an inner side thereof, such that two ends of each of said reinforcing members are detachably engaged with said longitudinal slots of two of said beam members to reinforce said beam members and to retain a fixed distance therebetween. 
     
     
         15 . The frame, as recited in  claim 14 , wherein each of said reinforcing members has a reinforcing panel and two coupling latches extended from two ends of said reinforcing panel respectively to slidably engage with said longitudinal slots of two of said beam members respectively, wherein said longitudinal slot has a shape and size matching with said coupling latch. 
     
     
         16 . The frame, as recited in  claim 15 , wherein said coupling latches are opposedly extended from said two ends of said reinforcing panel respectively.
