CPU heat sink mount attachment structure

Abstract

A CPU heat sink mount attachment structure including a retaining pin member, a spring member and an inner retaining pin, characterized in that the inner retaining pin is structured to comprise a main body and a reset button, and the inner retaining pin and the spring member are disposed within the retaining pin member. When the main body of the inner retaining pin is pressed downward, a retaining pin within the main body props pin-foot at a bottom portion of the retaining pin member. Furthermore, catch hooks within the main body mutually clasp with corresponding catch hooks of the retaining pin member, thereby achieving the object of securing the main body. Accordingly, the aforementioned structure can be used to quickly and expediently assemble and disassemble a heat sink mount.

1 . A CPU heat sink mount attachment structure comprising a retaining pin member, a spring member and an inner retaining pin, comprising; 
 the retaining pin member is provided with a through hole central thereof, and interior of the retaining pin member is provided with a holding space for containing the spring member and the inner retaining pin, an outer side wall of the retaining pin member is provided with catch hooks and anti-rotation locating structures, and a bottom portion of the retaining pin member is provided with downward extending pin-foot, a slot opening is defined central of the pin-foot;    the inner retaining pin is structured to comprise a main body and a reset button, the main body is provided with a downward extending retaining pin and catch hooks, an outer side wall of the main body is provided with a yield notch and locating slide grooves, a bottom portion of the reset button is provided with a pushing block and a pad block, moreover, locating slide blocks are configured on the reset button corresponding to the locating slide grooves of the main body.    
   
   
       2 . The CPU heat sink mount attachment structure according to  claim 1 , comprising an escapement is configured between the main body and the retaining pin member, which uses a limit aperture defined in a rear of the main body, and a corresponding limit catch hook disposed on the retaining pin member, whereby after assembling the main body and the retaining pin member, the limit catch hook is confined to straight movement within the limit aperture, thereby preventing separation.
