Combinational gardening rack

Abstract

A combinational gardening rack comprising several frames, several combining connectors and a hood; the major feature of the present invention is that the combining connectors have vertical and horizontal connecting holes with same diameter, the vertical connecting hole is hollow in center, a wedge stretches out from the bottom of the vertical connecting hole, a locking mechanism is on the wedge. While assembly based on the structure described above, users can apply the wedges and locking mechanisms to assemble the frames and the combining connectors together at any height on the vertical frames, such scheme can adjust the height between layers of the rack.

1 . A combinational gardening rack comprising: 
 several frames, several combining connectors and a hood, said combining connectors have vertical and horizontal connecting holes, said vertical connecting hole is hollow in center, a wedge stretches out from the bottom of said vertical connecting hole, a locking mechanism is on said wedge, said locking mechanism fixes said wedge of said combining connectors onto said vertical frames.    
   
   
       2 . The combinational gardening rack recited in  claim 1 , wherein said frames subdivide into several vertical frames, several horizontal frames, a top frame and several frame boards, the length of said vertical frame is close to the length of the rack, the external diameter of said vertical frame corresponds to the diameter of said vertical connecting holes that is vertical to said combining connectors.  
   
   
       3 . The combinational gardening rack recited in  claim 2 , wherein said combining connectors is in horizontal rod shape, one said vertical connecting hole and one said horizontal connecting hole both are on both ends of said combining connectors, said wedge is on the bottom of said vertical connecting hole, said locking mechanism is on said wedge.  
   
   
       4 . The combinational gardening rack recited in  claim 2 , wherein said combining mechanism has two horizontal connecting holes on two sides of said hollow vertical connecting hole, said wedge and said locking mechanism are beneath said vertical connecting hole.  
   
   
       5 . The combinational gardening rack recited in  claim 3  or  claim 4 , wherein several small crevices are on the bottom of said wedge, threads is above said crevices, said locking mechanism is in round shape, another set of threads corresponding to said threads is inside said locking mechanism, a protruding inner circumference is on the bottom of said locking mechanism.
