Embodiment

See also Fig. 1-shown in Figure 3, mean out that fan Fixture 3 of the present utility model is assembled on the computer housing 1, and be fixed thereon for a fan 2.This computer housing 1 has side plate 10, has a plurality of perforation that run through 11 on this side plate 10.This fan 2 has a deckle board 20 and four fixed screw holes 21, and this deckle board 20 is positioned at a side, and these four fixed screw holes 21 are positioned at four corners.This fan Fixture 3 is assembled in the inner side surface of this side plate 10, and this fan Fixture 3 comprises a pedestal 30 and a filter screen 40.Wherein:

This pedestal 30 is incorporated on this side plate 10, and has one first side 31, one second side 32 and an inlet air hole 33.This first side 31 is towards this side plate 10, and has a slot 310, and this slot 310 is formed with one up and inserts mouthfuls 311.This second side 32 is positioned at the back side of this first side 31, and has the protruding grain 324 of a tank 320, a button hook 321, two cramps 322, two elasticity projections 323 and two elasticity.This tank 320 is for 20 deckle boards that hold this fan 2.The upside cell wall that this button hook 321 extends from this tank 320, and have a hook part 325 can be for colluding the lateral margin of the another side of being located at this fan 2.This two cramp 322 inwardly protrudes out a length by the both sides of the downside cell wall of this tank 320, makes the inner side surface that can clamp in this deckle board 20.This two elasticity projection 323 is arranged in two corners of this tank 320 by upper side edge, can be sheathed for the fixed screw holes 21 of this fan 2.Respectively have an elasticity protruding grain 324 by the dual-side place towards a side of this side plate 10 system in this pedestal 30 in addition.This inlet air hole 33 is to be connected to this second side 32 by this first side 31.

This filter screen 40 comprises a framework 41 and a filter pulp 42.This framework 41 can be inserted in this slot 310 by this insertion mouth 311, has a frame groove 43, a frame hole 44, a protuberance 45 and two positioning holes 46 on this framework 41.This frame groove 43 is for holding this filter pulp 42, makes this framework 41 insert that this filter pulp 42 hides this inlet air hole 33 when being embedded in this slot 310.This frame hole 44 is connected to the another side by this frame groove 43, in this frame hole 44 and have a cell wall that a plurality of ribs 440 extend from this frame groove 43.This protuberance 45 convexedly stretches in the upper side edge of this framework 41, and is that a L-shaped lamellar body is to make things convenient for user's application of force.This two positioning hole 46 lays respectively at this framework 41 near the dual-side place, can embed for the protruding grain 324 of this two elasticity respectively.

See also Fig. 4, shown in Figure 5, the framework 41 of this filter screen 40 can be inserted in this slot 310 by this insertion mouth 311, so that this filter pulp 42 hides this inlet air hole 33, invades to prevent dust or insect.

See also shown in Figure 6ly, mean out that the protruding grain 324 of two elasticity on this pedestal 30 just can embed respectively in this two positioning hole 46, so that this framework 41 is positioned in this slot 310 when this framework 41 inserts in these slots 310 to a location.And because the protruding grain of this two elasticity 324 has an elastic force, therefore need impose a pulling force that is enough to overcome this elastic force can be with this framework 40 by pulling out in this slot 310.

See also shown in Figure 7, when this fan 2 is desired to be assembled on this fan Fixture 3, make deckle board 20 lower sides of this fan 2 insert the inboard of this two cramp 322 earlier, and then the upper side edge of this deckle board 20 is pressed in this tank 320, so that the lateral margin of the another side of being located at this fan 2 is colluded in the hook part 325 of this button hook 321.So just can easily and quickly this fan 2 be fixed on this fan Fixture 3 by the restriction of this hook part 325 and this two cramp 322.

When this fan 2 is incorporated on this fan Fixture 3, two fixed screw holes 21 of these fan 2 upsides just can two elasticity projections 323 of sheathed this pedestal 30 on.By being nested of this two elasticity projection 323 and this two fixed screw holes 21, this fan 2 can being located, and avoid this fan 2 in this tank 320, to move.

In addition, the utility model also can comprise two filter screens 40, and is provided with two inlet air holes 33 and two slots 310 in this pedestal 30, and this two slot 310 can plug for this two filter screen 40 respectively.Know by inference thus, the utility model also can comprise three or more filter screens certainly, and these pedestal 30 corresponding inlet air hole 33 and slots 310 that equal number is set, this only is the number change of the utility model feature, so no longer given unnecessary details.

In sum, owing to the utlity model has above-mentioned advantage and use value, and in like product, there is no similar products like or deliver the application important document that event has met utility model patent, be to file an application in the whence in accordance with the law.
