Computer casing having alignment line

Abstract

A computer casing for a computer includes a housing, and a side cover. The side cover has a plurality of locking hooks, at least one first straight side and at least one second straight side. The housing has at least one first side rail having a straight side and a plurality of locking slots and at least one second side rail having at least one alignment line. Thus, when the first straight side of the side cover aligns with the straight side of the first side rail of the housing and the second straight side of the side cover aligns with the alignment line of the second side rail of the housing, each of the locking hooks of the side cover is inserted into the respective locking slot of the first side rail.

1 . A computer casing, comprising a housing, and a side cover mounted on the housing, wherein:
 the side cover has an inner face and a plurality of locking hooks mounted on the inner face;   the inner face of the side cover has at least one first straight side and at least one second straight side perpendicular to the first straight side;   the housing has at least one first side rail facing the first straight side of the side cover and at least one second side rail facing the second straight side of the side cover and perpendicular to the first side rail;   the first side rail of the housing has a straight side aligning with the first straight side of the side cover and has a face formed with a plurality of locking slots to lock the locking hooks of the side cover;   the second side rail of the housing has at least one alignment line;   when the first straight side of the side cover aligns with the straight side of the first side rail of the housing and the second straight side of the side cover aligns with the alignment line of the second side rail of the housing, each of the locking hooks of the side cover is inserted into the respective locking slot of the first side rail.   
   
   
       2 . The computer casing in accordance with  claim 1 , wherein the alignment line has a depth. 
   
   
       3 . The computer casing in accordance with  claim 1 , wherein the second side rail of the housing has at least one indicating mark directed toward an outer side of the second side rail of the housing. 
   
   
       4 . The computer casing in accordance with  claim 3 , wherein the indicating mark is located adjacent to the alignment line. 
   
   
       5 . The computer casing in accordance with  claim 3 , wherein the side cover is movable toward the outer side of the second side rail of the housing by guidance of the indicating mark. 
   
   
       6 . The computer casing in accordance with  claim 1 , wherein the side cover is provided with a protruding handle to facilitate a user assembling and disassembling the side cover. 
   
   
       7 . The computer casing in accordance with  claim 1 , wherein each of the locking hooks of the side cover is inserted into the respective locking slot of the first side rail by guidance of the alignment line.
