The storage rack of  claim 8 , characterized in that the first locating member comprises a flange provided at the end of the second beam, wherein the second locating member comprises a slot provided in the first beam, the flange configured to be able to pass through the slot. 
     
     
         12 . The storage rack of  claim 8 , characterized in that the second beam comprises a second beam body and at least one reinforcing portion formed on the second beam body. 
     
     
         13 . The storage rack of  claim 12 , characterized in that the second beam body has two margins, an upper one of which projects outwardly and forms a third projection, wherein the first locating members are provided at an end of the third projection. 
     
     
         14 . The storage rack of  claim 13 , characterized in that a lower one of the two margins of the second beam projects outwardly and forms a fourth projection, wherein the first locating member is provided at an end of the fourth projection. 
     
     
         15 . The storage rack of  claim 12 , characterized in that the first locating member is provided at an end of the second beam body. 
     
     
         16 . The storage rack of  claim 14 , characterized in that one of the third projection and the fourth projection extends from its edge toward the other, forming a fifth projection which serves as the reinforcing portion of the second beam. 
     
     
         17 . The storage rack of  claim 14 , characterized in that the second beam body is bent to form a sixth projection which serves as the reinforcing portion of the second beam, the sixth projection comprising a first surface and a second surface, which intersect each other. 
     
     
         18 . The storage rack of  claim 8 , characterized in that the second locating member is not located at middle of the first beams. 
     
     
         19 . The storage rack of  claim 1 , characterized in further comprising a connecting member connecting a first vertical beam and a second vertical beam in sequence along length direction, the connecting member configured to restrict relative movement of the first vertical beam and the vertical beam in a non-vertical direction. 
     
     
         20 . The storage rack of  claim 19 , characterized in that the connecting member comprises a first body and a second body, which substantially perpendicularly intersect each other, the first body defining a first clamping portion along its edge away from the second body, the second body defining a second clamping portion along its edge away from the first body, the first clamping portion and the second clamping portion both having U-shaped cross-sections and thus defining therein channels adapted for insertion of the first vertical beam and second vertical beam therethrough.
