Computer enclosure with removable cover

Abstract

A computer enclosure includes a chassis having a back plate, a cover having a base plate, and a locking member pivotally positioned on the base plate, and two resilient members attached between the base plate and two ends of the locking member respectively. The locking member defines at least a locking protrusion thereon. The back plate defines a flange thereon for blocking the locking protrusion of the locking member. The locking member is in a first position when the two resilient members are in a normal state, and is in a second position when the two resilient members are resiliently deformed and the locking member rotated to a degree that the flange is free of the locking protrusion. The locking member is capable of rotating to move between the first and second positions. The flange latches the locking protrusion on the chassis, and the cover is attached on the chassis.

1 . A computer enclosure, comprising:
 a cover comprising a base plate, and a locking member pivotally positioned on the base plate, the locking member having at least a locking protrusion thereon;   a chassis comprising a back plate, the back plate having a flange thereon for engaging the locking protrusion of the locking member; and   two resilient members attached between the base plate and two ends of the locking member respectively, the locking member is in a first position when the two resilient members are in a normal state, and is in a second position when the two resilient members are resiliently deformed and the locking member rotated to a degree that the flange is free of the locking protrusion, the locking member is capable of rotating to move between the first and second positions, the flange latches the locking protrusion on the chassis, and the cover is attached on the chassis.   
     
     
         2 . The computer enclosure of  claim 1 , wherein the locking protrusion defines at least a slanted plane thereon, and the cover defines a first flange thereon, the flange of the back plate abuts the slanted plane, the locking member rotates to move between the first and second positions, the resilient members are resiliently deformed until the flange does not abut the locking protrusion in the second position, the resilient members are normal state and the flange latches the locking protrusion on the chassis in the first state. 
     
     
         3 . The computer enclosure of  claim 2 , further comprising a handle fixed on the locking member, the handle is pulled to drive the locking member from the first to the second position, when the flange of the back plate releases the slant plane of the locking protrusion, the resilient members are normal state, the locking member returns to the first position and the cover is detached from the chassis. 
     
     
         4 . The computer enclosure of  claim 3 , wherein the base plate defines two fixing members thereon for connecting with the two ends of the locking member respectively, each fixing member defines a pivotal hole thereon, the locking member defines two fixing holes at the two ends corresponding to the pivotal holes of the fixing member, two fasteners pass through the pivotal holes and the corresponding fixing holes to fix the locking member on the base plate. 
     
     
         5 . The computer enclosure of  claim 4 , wherein the locking member defines two fixing tabs thereon at a back adjacent to the two fixing holes, each fixing member defines a securing hole thereon, the resilient members are fixed on the corresponding fasteners between the two ends of the locking member and the fixing members respectively, each resilient member comprises a first distal end connected to the corresponding fixing tab, and a second distal end received in the corresponding securing hole. 
     
     
         6 . The computer enclosure of  claim 5 , wherein the resilient members are torsional springs. 
     
     
         7 . The computer enclosure of  claim 6 , wherein the handle comprises an actuating portion, and a connecting portion defining at least a through hole at a distal end, the locking member defines a locating hole in the middle corresponding to the through hole, a fastener passes through the locating hole and the through hole to fix the handle on the locking member. 
     
     
         8 . The computer enclosure of  claim 7 , wherein the connecting portion defines an accommodating hole thereon for receiving a resilient piece, the base plate defines a protrusion thereon between the two fixing members, a locating hole is positioned on the protrusion of the base plate for receiving the handle, two distal ends of the resilient piece resist two side edges of the locating hole, and the resilient piece is resiliently fixed on the base plate. 
     
     
         9 . The computer enclosure of  claim 8 , wherein the chassis further comprises a front plate opposite to the back plate, the front defines a flange thereon, and the cover defines a second flange thereon for engaging with the flange of the front plate.
