Structure for combining two sets of half-width rack-type machine cases to form a full-width machine case

Abstract

A structure for combining two sets of half-width rack-type machine cases to form a full-width machine case includes two half-width type machine cases to be combined together. Each half-width type machine case has one side plate provided with at least one positioning member protruding outward and another opposite side plate bored with receiving holes at the locations respectively corresponding with the positioning members. Thus, two half-width type machine cases abutting and juxtaposed can easily be combined into a full-width type machine case by having the positioning members of one half-width machine case engaged and fixed with the receiving holes of another half-width machine case.

1 . A structure for combining two sets of half-width rack-type machine cases to form a full-width machine case comprising two half-width type machine cases, which are juxtaposed so as to be combined together to form a full-width type machine case, said structure characterized by,
 each said half-width machine case having one side plate provided with at least one protruding positioning member, each said half-width machine case having an opposite side plate bored with receiving holes at locations corresponding with said positioning members, two said half-width machine cases able to be combined into a full-width machine case by mutual engagement of said positioning members and said receiving holes.   
     
     
         2 . The structure for combining two sets of half-width rack-type machine cases to form a full-width one as claimed in  claim 1 , wherein said positioning member is pivotally provided with a rotary member at a top portion. 
     
     
         3 . The structure for combining two sets of half-width rack-type machine cases to form a full-width machine case as claimed in  claim 1 , wherein each said receiving hole includes a round hole and an extension hole communicating with said round hole, hole diameter of said round hole being approximately the same as maximum diametrical width of said rotary member, hole diameter of said extension hole being a little smaller than a maximum width of said rotary member, said positioning member able to be moved transversely in said receiving hole to be engaged and positioned therein. 
     
     
         4 . The structure for combining two sets of half-width rack-type machine cases to form a full-width machine case as claimed in  claim 2 , wherein said rotary member is a bearing. 
     
     
         5 . The structure for combining two sets of half-width rack-type machine cases to form a full-width machine case as claimed in  claim 1 , wherein said positioning member is a bolt, and said side plate is bored with a corresponding threaded hole. 
     
     
         6 . The structure for combining two sets of half-width rack-type machine cases to form a full-width machine case as claimed in  claim 1 , wherein each said half-width machine case is provided with a back plate abutting and connecting said side plate, said back plate having two sides respectively bored with a locking hole, two locking members respectively inserted through a linking member and locked with said locking holes to lock and fix said linking member on said locking holes of two abutting half-width machine cases.
