Corner fixing block

Abstract

A corner fixing block having at least two fixing blocks of identical structure and a device body is disclosed. The first supporting surfaces of two fixing blocks are assembled in parallel, or two second supporting surfaces are assembled in parallel. Two fixing surfaces of two fixing blocks are used to form another fixing surface with a concave or a convex portion having a 90 degrees angle.

What is claimed is:  
     
         1 . A corner fixing block comprising: 
 two fixing blocks having an identical structure, the fixing block comprising: 
 a fixing surface;  
 a first supporting surface;  
 a second supporting surface;  
 a device surface;  
 a locking surface having a hole penetrating the locking surface and the fixing surface; and  
 a device body;  
 characterized in that: the two fixing blocks serves to connect the first supporting surfaces in parallel, then the device body is locked to the two device bodies of two fixing blocks by screws; screws pass through the holes on the locking surfaces of the two fixing blocks; the two fixing surfaces of the fixing blocks are locked to a fixing object having a vertical concave bending section (such as a beam) or a wall.  
   
     
     
         2 . The corner fixing block as claimed in  claim 1 , wherein the second supporting surfaces of two fixing blocks are connected in parallel; a screw serves to lock the device body to the two device surfaces; the device body is fixed to the fixing blocks; screws pass through the holes of the two locking surfaces of the fixing blocks; then the two fixing surfaces of the fixing blocks are locked to a retaining object having a portion protruded with 90 degree or a wall.  
     
     
         3 . The corner fixing block as claimed in  claim 1 , wherein protruding hooks are installed to fix the device body to the device surfaces of the two fixing blocks.  
     
     
         4 . The corner fixing block as claimed in  claim 1 , wherein in the assembly of the fixing blocks, a plurality of fixing blocks connected in parallel are used.
