Description

Buckling device of radiator

The utility model relates to a kind of buckling device of radiator, particularly a kind ofly installs and removes easy, the button solid buckling device of radiator that keeps steady.

Flourish along with electronic industry, it is more and more important that the heat dissipation problem of electronic building brick becomes, and corresponding buckling device of radiator design also emerges in an endless stream.Existing buckling device of radiator can be consulted Figure 1 and Figure 2, and it mainly is made up of some being embedded at the clip 1 of radiator 2 both sides.This clip 1 roughly is the T font, and top is the cantilever 12 that extends to two outsides, and is central then be the button portion 14 of extension downwards, and the Lower Half summary of this button portion 14 is diagonally extending and form a button hook 16 in the bottom inwardly inwardly.During assembling, cantilever 12 inlay cards of these clips 1 are in the caulking groove 22 of radiator 2 both sides, and the button hook 16 of bottom then is buckled in the bottom edge of electronic building brick 3, thereby radiator 2 and electronic building brick 3 end faces are fitted tightly together.But still there are many shortcomings in the said fixing mode, and details are as follows:

1. this buckling device of radiator is difficult for mounting or dismounting, and very easily deforms in assembling and dissembling process, even the situation of fracture.

2. this buckling device of radiator can only limit the lateral displacement of radiator, so this radiator may longitudinal sliding motion.

3. this buckling device of radiator is to utilize specific size design, and Lower Half slightly inwardly the button portion 14 of diagonally extending provide button to hold required strength, but that the button that these modes produced is held strength is very limited, and does not meet user demand.

Therefore, how to provide that a kind of mounting or dismounting are easy, button keeps steady solid and polarization buckling device of radiator is very important preferably.

The purpose of this utility model is to provide a kind of easy, button solid buckling device of radiator that keeps steady of installing and removing.

The purpose of this utility model is achieved through the following technical solutions: this buckling device of radiator comprises column sleeve, reference column and spring.Wherein this column sleeve is a hollow column, and its inside is formed with a through hole that vertically runs through, and offers short slot in the top level.Below corresponding short slot, this column sleeve runs through and offers elongate slot, and this slotted eye is connected with through hole.Below slotted eye, this column sleeve forms boss and afterbody successively, and wherein this boss is established ringwise toward evagination, and the end of afterbody then is formed with the opening of " ten " word shape.This reference column from top to bottom comprises end, cylinder, clamping part and barb portion successively, and wherein the both sides, middle part of this cylinder set out inverted triangle shape projection to evagination respectively, and the sectional area of this clamping part is less than the sectional area of barb portion.This spring is to be set in the column sleeve periphery.

Compared with prior art, the utlity model has following remarkable advantage: this buckling device of radiator is when loading and unloading, it is fixed in the column sleeve or with reference column in column sleeve, eject just execution but only need push this reference column, so it is quite convenient to operate, and in conjunction with firm.

The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.

Figure 10 is the combination of side view of the utility model buckling device of radiator and associated component.

See also Fig. 3, the utility model buckling device of radiator is to be used for radiator 80 is fitted tightly on electronic building brick 90, wherein this radiator 80 is made up of base 82 and some radiating fins 84, and the diagonal angle of these radiator 80 pedestals 82 symmetry respectively extends outward lug 86, all offers on each lug 86 for one group of hole 88 that buckling device of radiator wears.Every group of buckling device of radiator comprises column sleeve 60, reference column 40 and spring 50.

Please consult Fig. 4 and Fig. 5 simultaneously, this column sleeve 60 is a hollow column, and its inside is formed with the through hole 62 that vertically runs through, and offers short slot 64 in the top level.Below corresponding short slot 64, this column sleeve 60 runs through and offers elongate slot 66, and this slotted eye 66 is connected with through hole 62.Below slotted eye 66, this column sleeve 60 forms boss 68 and afterbody 72 successively, and wherein this boss 68 is established ringwise toward evagination, and the end of afterbody 72 then is formed with the opening 722 of " ten " word shape.The external diameter of this afterbody 72 makes in its button hole that can be arranged in circuit board 100 102 less than the aperture of circuit board 100 button holes 102.

Please consult Fig. 6 simultaneously, this reference column 40 from top to bottom comprises end 42, cylinder 44, clamping part 46 and barb portion 48 successively, wherein the both sides, middle part of this cylinder 44 set out inverted triangle shape projection 442 to evagination respectively, and the sectional area of this clamping part 46 is less than the sectional area of barb portion 48.

Please consult Fig. 7 simultaneously to Figure 10, during assembling, in the hole 88 of radiator 80 lugs 86 of earlier column sleeve 60 from bottom to top being packed into, prop up lug 86 bottom surfaces up to boss 68.Then, it is peripheral and place lug 86 tops spring 50 from top to bottom to be set in column sleeve 60.Then, reference column 40 is from top to bottom inserted in the through hole 62 of column sleeve 60, allow short slot 64 back (promptly state) as shown in Figure 7 of projection 442 rotary alignment column sleeves 60 of reference column 40 earlier, this reference column 40 of flicking moves its direction shown in the arrow A in Fig. 7 again, make the projection 442 of reference column 40 both sides snap in the slotted eye 66 at column sleeve 60 middle parts (promptly state) as shown in Figure 8, and allow this creation buckling device of radiator and radiator 80 combine in advance.Afterwards, radiator 80 is placed on electronic building brick 90 end faces, and the afterbody 72 of this column sleeve 60 is inserted in the button hole 102 on the circuit boards 100.At last, push the end 42 of reference column 40 downwards, make the barb portion 48 of reference column 40 pass " ten " word shape opening 722 of column sleeve 60, the afterbody 72 that forces column sleeve 60 elasticity outward struts the button hole 102 that withholds circuit board 100, this moment, this spring 50 was in compressive state, and afterbody 72 lower edges of column sleeve 60 are then hooked to prevent from oppositely to move (please refer to Fig. 9 and state shown in Figure 10) in the barb portion 48 of this reference column 40.
