Case structure for server

Abstract

A case structure suitable for a server is provided, which includes a first plate and a second plate. A fixing pillar is disposed on the first plate, and the second plate has a fixing rack with a locking portion and an assembly spring with a lock cooperating hole for being penetrated by the fixing pillar. The locking portion is used to lock an engaging portion of the fixing pillar so as to fix the second plate to an assembly position. When the assembly spring is activated by forces and departs from the fixing pillar, the second plate can be shifted from the assembly position to a disassembly position and departs from the first plate.

1 . A case structure for a server, comprising:
 a first plate, comprising a fixing pillar having an engaging portion; and   a second plate, disposed on the first plate, comprising a fixing rack and an assembly spring on a bottom thereof, wherein the fixing rack has a locking portion for locking the engaging portion of the fixing pillar so as to fix the second plate to an assembly position, and the assembly spring has a lock cooperating hole located above the locking portion, which is suitable for being penetrated by the fixing pillar,   wherein the assembly spring further has an elastic bending part normally relied upon the fixing rack, when the elastic bending part of the assembly spring is activated by forces and departs from the fixing pillar, the second plate is shifted from the assembly position to a disassembly position and departs from the first plate.   
   
   
       2 . The case structure for a server as claimed in  claim 1 , wherein the fixing rack has a slot, and the elastic bending part extends outside the slot to form an activating end. 
   
   
       3 . The case structure for a server as claimed in  claim 1 , wherein the locking portion comprises a V-shape slot. 
   
   
       4 . The case structure for a server as claimed in  claim 1 , wherein the engaging portion comprises a gap or an annular slot. 
   
   
       5 . The case structure for a server as claimed in  claim 1 , wherein the fixing pillar comprises a bolt or a rivet. 
   
   
       6 . The case structure for a server as claimed in  claim 1 , wherein the assembly spring comprises a metal elastic element. 
   
   
       7 . The case structure for a server as claimed in  claim 1 , wherein the second plate comprises two sidewalls and a middle flat part between the two sidewalls, and the fixing rack and the assembly spring are disposed on the middle flat part. 
   
   
       8 . A case structure for a server, comprising:
 a first plate, comprising a fixing pillar having a groove;   a second plate, disposed on the first plate, comprising a fixing rack and an assembly spring on a bottom thereof, wherein the fixing rack has a locking portion disposed along a horizontal moving direction, and the locking portion has an opening width at a first position less than that at a second position, the assembly spring has a lock cooperating hole located corresponding to the first position, and when the second plate moves along the horizontal moving direction and the groove is located at the first position of the locking portion, the fixing pillar is locked to the locking portion, and the lock cooperating hole is suitable for being penetrated by the fixing pillar.   
   
   
       9 . The case structure for a server as claimed in  claim 8 , wherein the locking rack has a slot, the assembly spring has an elastic bending part relied upon the fixing rack, and the elastic bending part extends outside the slot to form an activating end. 
   
   
       10 . The case structure for a server as claimed in  claim 8 , wherein the locking portion comprises a gourdshaped hole. 
   
   
       11 . The case structure for a server as claimed in  claim 8 , wherein the locking portion comprises a V-shape slot, and the opening width of a tip end of the V-shape slot at the first position is less than that of an opening end of the V-shape slot at the second position. 
   
   
       12 . The case structure for a server as claimed in  claim 8 , wherein the assembly spring comprises a metal elastic element.
