The main body is provided with two winged portions which are located at both ends thereof and provided with a through hole.
Description




FIELD OF THE INVENTION




The present invention relates generally to a cooling piece of the central processing unit of a computer, and more particularly to a retaining device of the central processing unit (CPU) cooling piece.




BACKGROUND OF THE INVENTION




As shown in

FIG. 1

, a prior art retaining device


80


of the CPU cooling device comprises a long plate


81


which is provided at both ends thereof with a leg


82


. The two legs


82


are provided at the end thereof with a curved retainer


83


of an S-shaped construction and facing each other, and in the outer side of the body thereof with a side hook


84


extending downwards and outwards. As shown in

FIG. 2

, the retaining device


80


at work is disposed across a cooling piece


85


such that the curved retainers


83


of the two legs


82


catch the CPU heat conductive piece


87


located at the bottom of the cooling piece


85


.




Such a prior art retaining device


80


as described above has shortcomings, which are described hereinafter.




In the processing of installing the prior art retaining device


80


, both ends of the retaining device


80


must be pressed. As a result, the retaining device


80


can not be easily installed on the cooling piece


85


and the CPU heat conductive piece


87


. Both ends of the retaining device


80


are located under a fan


88


of the cooling piece, as shown by the imaginary lines. The fan


88


obstructs the hand with which both ends of the retaining device


80


are pressed. The fan


88


also obstruct the view of a person working to install the retaining device


80


. In addition, the fingers of the person are obstructed by the cooling plates


86


located at the top of the cooling piece


85


at the time when both ends of the retaining device


80


are pressed with the fingers.




The retaining device


80


can not be easily detached without the help of a slotted screwdriver


89


as shown by the imaginary lines. The screwdriver


89


is used to press against the side hook


84


for actuating the leg


82


to displace upwards and outwards, thereby causing the curved retainer


84


to slip out so as to enable the retaining device


80


to be moved away from the bottom of the CPU conductive piece


87


. In addition, the screwdriver


89


is used under the circumstance that there is a lack of point of application, and that the cooling piece


85


is used as a fulcrum on which the leg


82


is taken out. In short, the computer is provided with a limited space in which the screwdriver


89


can not be easily maneuvered.




SUMMARY OF THE INVENTION




It is therefore the primary objective of the present invention to provide a device for retaining a CPU cooling device. The retaining device can be easily mounted and dismounted.




In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by a retaining device comprising a main body which is provided with two legs opposite to each other. Each leg is provided with a hook extending outwards and upwards, and a retainer. The main body is provided at both ends thereof with a winged portion extending outwards and having a through hole.




The objective, features, functions, and advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION




As shown in

FIG. 3

, a device


10


embodied in the present invention is designed to retain the computer CPU cooling piece. The device


10


comprises a main body


11


having two raised segments opposite to each other such that the main body II has a V-shaped longitudinal section. The two raised segments of the main body


11


are provided with a through hole


13


and a leg


15


which is located at the outer side of the through hole


13


and is provided with a hook


16


extending outwards and upwards. The leg


15


is provided at one end thereof with a curved retainer


17


extending upwards. The curved retainers


17


of the two legs


15


face each other. The main body


11


is provided at both ends thereof with a winged portion


21


, which is in turn provided with a through hole


22


.




As shown in

FIG. 4

, the cooling piece is mounted on the CPU heat conductive piece such that the two winged portions


21


of the retaining device


10


are held with hand, and that two sides of the CPU cooling piece


40


are pressed against by the two legs


15


, as illustrated by the imaginary lines, and further that the two winged portions


21


are pressed downwards so as to cause the midsegment of the main body


11


to come in contact with the top of the cooling piece


40


. As the two winged portions


21


are further pressed downwards, the raised segments of the main body


11


bounce back up such that the retainer


17


moves through the cooling piece


40


and the side wall of the CPU heat conductive piece


50


so as to catch the bottom wall of the CPU heat conductive piece


50


. In the meantime, the bouncing action of the two raised segments of the main body


11


causes the retainer


23


to catch securely the bottom wall of the CPU heat conductive piece


50


. As a result, the cooling piece


40


is securely held in place on the heat conductive piece


50


. In light of the two winged portions


21


being jutted out of the legs


15


, as well as the cooling piece


40


, the winged portions


21


are not obstructed by the fan


60


located over the cooling piece


40


and the cooling plate


41


located on the cooling piece at such time when the two winged portions


21


are forced downwards. Moreover, the two winged portions


21


are visible to an operator.




Now referring to

FIG. 5

, a screwdriver


70


, which is shown by the imaginary lines, is shown to be inserted into the through hole


23


of one winged portion


21


such that the tip of the screwdriver


70


is engaged with the hook


16


. The screwdriver


70


is then moved outwards on a fulcrum which is the contact portion between the screwdriver


70


and the winged portion


21


. As a result, the hook


16


and the leg


15


are actuated to move outwards such that the retainer


17


moves away from the heat conductive piece


50


, and that the raised segments of the main body


11


move back up to their original positions to cause the retainer


17


to move away from the retaining position. As a result, the retaining device


10


is detached.




As shown in

FIG. 6

, the screwdriver


70


is inserted into the through hole (not shown in the drawing) of the main body


11


such that the screwdriver


70


is located between the leg


15


and the cooling piece


40


, as shown by the imaginary lines. As the tip of the screwdriver


70


is moved outwards, the retainer


17


of the leg


15


is caused to move away from the bottom wall of the heat conductive piece


50


, thereby resulting in the detachment of the retaining device


10


of the present invention.




The two legs


15


of the present invention may be fastened with the main body


11


of the present invention by welding in place of punching and pressing. Under such a circumstance, a screwdriver is used to detach the retaining device such that the screwdriver is engaged with the hook


16


via the through hole


22


of the winged portion


21


, so as to take the leg


15


out.




The present invention has advantages, which are described hereinafter.




The present invention can be easily installed in view of the fact that the two winged portions


21


are jutted out of the cooling piece


40


to avoid being obstructed by the fan


60


located over the cooling piece


40


, and that the winged portions


21


are clearly visible to an operator installing the device of the present invention, and further that the winged portions


21


are not obstructed in any way by the cooling plate


41


located on the cooling piece


40


.




The present invention can be easily dismounted by using a screwdriver


70


which is inserted into the through hole


22


of the winged portions


21


to engage the hook


16


. The dismounting of the present invention is done with the screwdriver


70


by making use of the winged portion


21


as a fulcrum. The cooling piece


40


is not used as a fulcrum to engage in the work of dismounting the device of the present, thereby providing the cooling piece


40


with protection against damage.
