Component coupled to heat dissipation unit

Abstract

A component coupled to a heat dissipation unit, allowing a screwing element to be pivotally coupled to a heat dissipation unit, includes a body, a stop portion, a first inner engagement portion, a second inner engagement portion and a first outer engagement portion. The body has a first part and a second part and forms therein a through hole which extends axially. The stop portion is circumferentially disposed at the rim of the first or second part. The first inner engagement portion has checking plates and corresponds in position to the stop portion. The second inner engagement portion has stop blocks disposed at the first or second part. The first outer engagement portion is disposed at the rim of the body and opposite the stop portion. The screwing element is fixed to the heat dissipation unit temporarily but firmly, thereby preventing disintegration and disconnection during transport.

What is claimed is: 
     
         1 . A component coupled to a heat dissipation unit, allowing a screwing element to be pivotally coupled to a heat dissipation unit, the component comprising:
 a body having a first part and a second part, with the first and second parts connected to each other and disposed at two ends of the body, respectively, the body forming therein a through hole extending axially to penetrate the first and second parts of the body;   a stop portion circumferentially disposed at a rim of one of the first and second parts selectively;   a first inner engagement portion having a plurality of checking plates each extending from a through-hole-defining inner wall of the body to a center of the through hole radially, with the first inner engagement portion corresponding in position to the stop portion; and   a first outer engagement portion disposed opposite the stop portion and formed by extending a rim of the body outward.   
     
     
         2 . The component of  claim 1 , wherein the checking plates each have a first end surface and a second end surface which face upward and downward substantially, respectively, and one of the first and second end surfaces is oblique. 
     
     
         3 . The component of  claim 1 , further comprising a second inner engagement portion selectively disposed at one of the first and second parts, with the second inner engagement portion having a plurality of stop blocks, the stop blocks each extending from the through-hole-defining inner wall of the body to the center of the through hole radially and each having a first top surface and a second top surface, with the first and second top surfaces disposed at two ends of each said stop block, respectively, wherein one of the first and second top surfaces is oblique. 
     
     
         4 . The component of  claim 3 , wherein the stop blocks are disposed on the through-hole-defining inner wall surface of the body in one of a continuous axial manner and a discontinuous axial manner. 
     
     
         5 . The component of  claim 1 , wherein at least a first axial slot and a second axial slot are disposed at the body, positioned opposite the stop portion and corresponding to each other in a manner that the first and second axial slots are disposed at the rim of the body, extend axially, communicate with the through hole of the body, and define a first clasp portion and a second clasp portion at the rim of the body. 
     
     
         6 . The component of  claim 1 , wherein at least a first axial slot, a second axial slot and a third axial slot are disposed at the body, positioned opposite the stop portion and angularly spaced apart by 120° in a manner that the first, second and third axial slots are disposed at the rim of the body, extend axially, communicate with the through hole of the body, and define a first clasp portion, a second clasp portion and a third clasp portion at the rim of the body. 
     
     
         7 . The component of  claim 1 , wherein the body further has a third part and a second outer engagement portion, with the third part connected to the first part, the second outer engagement portion disposed at a rim of a free end of the third part and extending outward therefrom, and the first and second outer engagement portions each having at least a conical surface disposed on a top surface of the second outer engagement portion. 
     
     
         8 . The component of  claim 7 , wherein the stop blocks are disposed between the first and third parts and disposed on the through-hole-defining inner wall surface of the body in one of a continuous axial manner and a discontinuous axial manner. 
     
     
         9 . The component of  claim 7 , wherein at least a fifth axial slot and a sixth axial slot are disposed at the body, positioned opposite the stop portion and corresponding to each other in a manner that the fifth and sixth axial slots are disposed at the rim of the body, extend axially, communicate with the through hole of the body, and define a fifth clasp portion and a sixth clasp portion at the rim of the body. 
     
     
         10 . The component of  claim 7 , wherein at least a fifth axial slot, a sixth axial slot and a seventh axial slot are disposed at the body, positioned opposite the stop portion and angularly spaced apart by 120° in a manner that the fifth, sixth and seventh axial slots are disposed at the rim of the body, extend axially, communicate with the through hole of the body, and define a fifth clasp portion, a sixth clasp portion and a seventh clasp portion at the rim of the body.
