Storage box

Abstract

A storage box includes alternately arranged latch structures and protrusions disposed on an end of a side panel, latch holes, and recessions corresponding to the latch structures and protrusions disposed on the other end of the side panel, such that four side panels are coupled to form a frame. The bottom of each side panel includes a limit groove such that four sides of a bottom board are fixed into these limit grooves to serve as the bottom of the storage box. If the storage boxes are arranged side by side with each other, the protrusion on a fixture is latched into a connecting section, so as to fix the corresponding positions of the side-by-side storage boxes. The side-by-side boxes are fixed with each other by inserting a hook structure separately disposed on both sides of a limit component into a groove disposed at the top of each side panel.

1 . A storage box, comprising: 
 four identical side panels, each having alternatively arranged latch structures and protrusions disposed on an edge of the side panel, and latch holes and recessions disposed on the other end of the side panel and corresponding to the latch structure and the protrusions, such that the four side panels are coupled to form a frame, and a bottom side being disposed on an end of both edges of the side panel and a limit groove being disposed at an internal side of the bottom side;    a bottom board, including four sides to correspond with the limit grooves for being inserted into and fixed to the limit grooves; and    a folding line structure, disposed at the middle of the bottom board for folding the bottom board.    
   
   
       2 . The storage box of  claim 1 , wherein the bottom side includes a top side disposed at a corresponding side and a handle section disposed proximate to the top side.  
   
   
       3 . The storage box of  claim 1 , wherein the bottom side includes a groove disposed at an internal side of the top side corresponding to the bottom side, such that when the storage boxes are arranged side by side with each other, the latch structure disposed separately on both sides of a fixture is latched into two grooves to limit the corresponding position of the side-by-side storage boxes.  
   
   
       4 . The storage box of  claim 1 , wherein the side panel includes a connecting section disposed at an edge of the alternately arranged latch structures and the protrusions and proximate to the limit groove, and a penetrating hole disposed on another edge and corresponding to the connecting section.  
   
   
       5 . The storage box of  claim 3 , further comprising an insert section of a wheel component for being inserted into the connecting section through the penetrating hole.  
   
   
       6 . The storage box of  claim 3 , wherein when the storage boxes are placed side by side and a protrusion of a fixture is latched into the connecting section through the penetrating hole to fix the corresponding positions of the storage boxes.  
   
   
       7 . The storage box of  claim 6 , wherein the fixture is in a long bar shape and includes a protrusion separately disposed on both ends of a side of the fixture.  
   
   
       8 . The storage box of  claim 6 , wherein the fixture is in an L-shape and includes a protrusion separately disposed on both ends and a bent position of the fixture.  
   
   
       9 . The storage box of  claim 6 , wherein the fixture is a rectangular fixture and includes a protrusion disposed at each of the four corners on the surface of the fixture.
