Description

Anchor clamps

Technical field

The utility model is to be used for locating the parts of radiator so that add the anchor clamps of thermal weld about a kind of, is meant especially a kind ofly can clamp easily and unclamp the parts of radiator so that add the anchor clamps of thermal weld.

Background technology

Central processing unit can produce heat when work, as untimely heat is taken away and will be influenced the stable operation of central processing unit, common practices is that a radiator is installed on the surface of central processing unit, and a fan is installed on its radiating fin again, the heat that central processing unit is produced conducts on the radiating fin, and the blow cold air that produces by fan is dispelled the heat to the gap of some radiating fins again.Some radiator not only is provided with pedestal and some radiating fins, also is provided with heat pipe simultaneously.One end of these heat pipes interts in the perforation of radiating fin after coating tin cream, the other end is folded between the pedestal and radiating fin of radiator after coating tin cream, deliver in the reflow soldering then and weld, pedestal, heat pipe and radiating fin are welded into an integral body.For the quality that guarantees to weld, be sent in the reflow soldering again after generally adopting anchor clamps to be fixedly clamped radiating fin, pedestal and the heat pipe of radiator together and weld.

Anchor clamps commonly used are shown in No. the 92217340th, Taiwan patent application, and it comprises a base, be separately fixed at two positioning seats and a block pressur plate at base two ends.Want during use on the arcuate base of radiator, to coat tin cream earlier, again the radiating fin correspondence is attached on this arcuate base, and then above this radiator, cover pressing plate, tighten the nut on the screw rod again, make this pressing plate clamp this radiator, guarantee that radiating fin contacts with the tight of arcuate base, send in the reflow soldering again and weld, back-out nut again after making radiating fin and arcuate base solid welding together, take off pressing plate, thereby this radiator is separated from anchor clamps.Yet, this anchor clamps will overlap top board after loading onto radiator, again nut is reversed a lot of circles on screw rod and can clamp pressing plate, when taking off radiator, also nut to be reversed a lot of circles on screw rod, just can back-out nut and take off pressing plate, process is more time-consuming, and higher by the temperature of reflow soldering rear jig, be not suitable for back-outing tiny nut, remain in fact to be improved with pushing phase operation.

Summary of the invention

The purpose of this utility model is to provide a kind of and is used for locating the parts of radiator so that add the anchor clamps of thermal weld, is meant especially a kind ofly can clamp easily and unclamp the parts of radiator so that add the anchor clamps of thermal weld.

For achieving the above object, the utility model provides a kind of and is used for locating the parts of radiator so that add the anchor clamps of thermal weld, these anchor clamps comprise a base, two buckling and locking devices and a pressing plate, at least be provided with a groove that is used for being installed with radiator base on this base, the both sides correspondence of this base respectively is provided with a pillar; This two buckling and locking device is installed in this post top portion, and it comprises two screw rods and be set in two locking parts on the two screw rods respectively that this two locking part can be the axle center rotation with the screw rod; This pressing plate is the pedestal that is used for the radiating fin of radiator closely is crimped onto radiator, and after again this two locking part being rotated a corner, thereby promptly latchablely becomes a firm combination on pressing plate.

The utlity model has following beneficial effect: these anchor clamps when locking by acting on the outer end of two locking parts, after making two locking parts rotate a corner, just can make its kayser on pressing plate, become a firm combination, and when splitting, make two locking part reverse rotations, one corner again, can unclamp pressing plate and take out the radiator of its below, simple and efficient to handle, efficient is higher.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail:

See also Fig. 1 to Fig. 3, a kind ofly be used for locating the parts of radiator 7 so that add the anchor clamps of thermal weld, these anchor clamps comprise a base 1, two buckling and locking devices 3 and a pressing plate 6.

This radiator 7 comprises a pedestal 72, some radiating fins 74 and a heat pipe 76 that is connected between pedestal 72 and the radiating fin 74.

These base 1 central authorities are provided with two grooves 10 that are used for being installed with radiator 7 pedestals 72, and the both sides correspondence of this base 1 respectively is provided with a pillar 12, and these pillar 12 tops are provided with a female screw 13 of processing; Be provided with a projection 14 between this two groove 10, the both sides of this projection 14 respectively stretch out a registration arm 16 that is used for assisting for radiating fin 74 location; This base 1 also is provided with a baffle plate 18 that is used for to heat pipe 76 assist location of radiator 7 in a side of each groove 10; For conveniently gripping this anchor clamps, the two ends of this base 1 further are provided with the handle 20 that a pair of operating personnel of confession grip simultaneously.

This two buckling and locking device 3 is installed in pillar 12 tops of this base 1, and it comprises that two are installed in the screw rod 32 in these pressing plate 6 outsides and are set in two locking parts 34, two packing rings 36 and two springs 35 on the two screw rods 32 respectively.One end of this screw rod 32 is provided with external screw thread 37, and its other end is provided with a spiral shell head 40, and wherein to be provided with an end of external screw thread 37 be to twist in the screw 13 be affixed to this pillar 12 to this screw rod 32.This locking part 34 is bodies of rod that a middle part offers a through hole 31 that wears for screw rod 32, and this locking part 34 can be that the axle center rotates with screw rod 32.This packing ring 36 is set between spiral shell head 40 and the locking part 34, prevent that this locking part 34 from deviating from from screw rod 32, and this spring 35 is to be set in this locking part 34 belows, between locking part 34 and this pillar 12.

These pressing plate 6 both sides central authorities respectively are provided with a breach 62, and this breach 62 can match with this two pillar 12 and assist this pressing plate 1 location, thereby prevent that this pressing plate 6 from slippages taking place.This pressing plate 6 is provided with several through holes 64, not only saves material, and can strengthen the ventilation heat radiation.

Radiator 7 pedestals 72 that will be brushed with tin cream are in use earlier put in the groove 10, the radiating fin 74 that will be equiped with heat pipe 76 again is attached on the pedestal 72, add top board 6 in radiating fin 74 over top again, use one to add press (figure does not show) and add and be pressed on the pressing plate 6, radiating fin 74 and pedestal 72 are clamped together, and then act on the outer end of two locking parts 34, make 34 one of the rotation of two locking parts be not more than the corner of 90 degree, thereby be the latchable firm combination that on pressing plate 6, becomes, just can and be installed in radiator 7 on these anchor clamps then and be sent in the reflow soldering simultaneously and weld, the radiating fin 74 of radiator 7 is welded on the pedestal 72 these anchor clamps.

These anchor clamps by acting on the outer end of two locking parts 34, make 34 one of the rotation of two locking parts be not more than the corner of 90 degree when locking, just can make its kayser become a firm combination on pressing plate 6; And when splitting, make one of two locking parts, 34 reverse rotation be not more than the corner of 90 degree again, and can unclamp pressing plate 6 and take out the radiator 7 of its below, simple and efficient to handle, efficient is higher.

The above; only be one of preferable feasible embodiment of the utility model; can not therefore promptly limit to interest field of the present utility model; concerning being familiar with those of ordinary skill in the art; such as use the technical solution of the utility model and technical conceive to make other various corresponding changes and distortion, and all these changes and distortion all should belong within the protection domain of the utility model claim.
