Retractable Electrical Casing Structure

Abstract

A retractable electrical casing structure includes a casing and a sliding bracket connected to the casing. The casing comprises a hollow body and sliding members. The sliding bracket comprises sliding sections. The sliding bracket is able to slide with respect to the casing to vary the size of the electrical casing.

1 . A retractable electrical casing structure comprising a casing and a sliding bracket, said casing having a hollow body, said sliding bracket being connected to said casing in a slidable way, and characterized by:
 said casing comprising sliding members at inner sides thereof, said sliding bracket comprising sliding sections corresponding to said sliding members.   
   
   
       2 . The retractable electrical casing structure, as recited in  claim 1 , wherein said casing comprises a pair of locating plates at the inner sides thereof, said sliding members being disposed on said locating plates. 
   
   
       3 . The retractable electrical casing structure, as recited in  claim 1 , wherein said sliding bracket comprises a pair of locating plates, said sliding sections being disposed on said locating plates. 
   
   
       4 . The retractable electrical casing structure, as recited in  claim 1 , wherein said sliding members of said casing are studs, and said sliding sections of said sliding bracket are slots. 
   
   
       5 . The retractable electrical casing structure, as recited in  claim 2 , wherein said sliding members of said casing are studs, and said sliding sections of said sliding bracket are slots. 
   
   
       6 . The retractable electrical casing structure, as recited in  claim 3 , wherein said sliding members of said casing are studs, and said sliding sections of said sliding bracket are slots. 
   
   
       7 . The retractable electrical casing structure, as recited in  claim 1 , wherein said casing comprises locating blocks at the inner sides thereof, and said sliding bracket comprises locating slots corresponding to said locating blocks. 
   
   
       8 . The retractable electrical casing structure, as recited in  claim 1 , wherein said casing is provided with a cover. 
   
   
       9 . The retractable electrical casing structure, as recited in  claim 8 , wherein said casing comprises threaded holes on its edge, and said cover comprises through holes corresponding to said threaded holes of said casing for insertion of fasteners to secure said cover to said casing.
