Description

Fan Fixture

[technical field]

The utility model is about a kind of fan Fixture, refers to a kind of easy for installation, fan Fixture of being easy to dismantle especially.

[technical background]

In the background technique, the main heating source of computer is the central processing unit (CPU) on the host board, generally is by the fan that is installed in power supply unit the heat that central processing unit (CPU) produced to be discharged casing.In order to reach better radiating effect, the fan of independent running is installed on the header board of casing in addition, suck the cooling air of casing outside, and cooperate the fan of this power supply unit in casing, to produce cross-ventilation.

As Chinese patent ZL99240663.3 number, be that a fan is installed in the header board that is fixed on computer housing behind the fan Fixture of a tool inclined wall again, make this fan and this header board be used at angle blowing over against central processing unit (CPU).This fan Fixture hangs the fixing mouth of casing header board earlier by its holding division and as rotating shaft, rotating this fan Fixture can make the fixing sheet enter in the corresponding fixing mouth, fix in the mouth corresponding by its elastic hook card division is solid more at last, thereby this fan Fixture that fan is installed is fixed on this header board.

But, when this casing header board is dismantled this fan Fixture, need the operator elastic hook card division to be applied certain active force it is compressed with hand with by assistant tool after, just can from corresponding clamping hole, fan Fixture be taken off.It is very inconvenient that this kind fan Fixture is not only operated effort, and might damage header board and damage finger.

[summary of the invention]

The purpose of this utility model is to provide a kind of easy and simple to handle, easy fan Fixture of dismounting.

The purpose of this utility model realizes by being used for down technological scheme: a fan Fixture is used for a fan is installed in the header board of a computer housing.This fan Fixture comprises that a substrate and is funnelform main body.To should fan, this substrate center forms a circular hole, and this circular hole periphery is established some locking holes.This main body is formed by connecting by some walls of the oblique extension of this substrate periphery certainly.These walls comprise a roof, one with adjacent the first side wall and one second sidewall of this roof, a diapire relative with this roof.This roof outer rim is convexly equipped with the pair of L-shaped snap hook, offers a block button hole respectively on the wall body of the contiguous outer rim of this first side wall and second sidewall, and the outer rim of this first side wall is convexly equipped with one and comprises that one detains the operating body of a piece and a press part.

By adopting technique scheme, easy and simple to handle, the easy advantage of dismounting that the utility model fan Fixture has.

[description of drawings] the utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.Fig. 1 is the three-dimensional exploded view of the utility model fan Fixture and associated component.Fig. 2 is the stereogram of the utility model fan Fixture.Fig. 3 is the three-dimensional combination figure of the utility model fan Fixture and associated component.Fig. 4 is the partial enlarged drawing of the utility model fan Fixture Fig. 3.

[embodiment]

Please refer to Fig. 1, fan Fixture 30 of the present utility model is a fan 40 to be installed in the header board 20 of a computer housing, thereby the outer Cryogenic air of casing is blowed through these fan 40 suctions and the heating electronic device spare to casing inside.

Please be simultaneously with reference to Fig. 2, this fan Fixture 30 comprises that a substrate 31 and is funnelform main body 33.This substrate 31 is square plate bodys, and its central position is offered a circular hole 311, and the appropriate position of four drift angles outside these circular hole 311 circumference offers some locking holes 312 respectively.An oblique roof 332, a first side wall 334, one second sidewall 336 and the diapire 338 of extending in the surrounding of this substrate 31, these walls are interconnected to form this main body 33.This roof 332 is adjacent with the first side wall 334, second sidewall 336 respectively, and over against this diapire 338.This main body 33 is surrounded with this substrate 31 and is formed a cavity 38, and the circular hole 311 of the opening end of this cavity 38 and this substrate 31 is relative.

The outer knuckle of this roof 35 outwards protrudes and bends in the same way and extends to form two L shaped snap hooks 35, and this first side wall 334 and second sidewall 336 are offered a block button hole 37 respectively near on the wall bodies of outer knuckle, these block button hole 37 contiguous these diapires 338.This first side wall 334 knuckle outside it is convexly equipped with an operating body 39, this operating body 39 tools one L shaped joint 391, and the first portion that this L shaped joint 391 is parallel to this substrate 31 extends from this first side wall 334, is convexly equipped with a square button piece 392 on it.The terminal press part 393 that connects of the second portion of this joint 391, this press part 393 is parallel to this substrate 31.The application of force direction of this operation unit 39 is consistent with the engaging direction of these snap hooks 35.

This header board 20 is installed in the front end of computer housing.To cavity 38 that should fan Fixture 30, this header board 20 is provided with the zone 25 of the some vent holes of a tool.These 25 tops, zone are offered two and are used for and the snap hook 35 of fan Fixture 30 button hole 21 of buckle mutually.These 25 bottoms, zone outwards are convexly equipped with two and are used for the L shaped clasp 23 that holds mutually with the block button hole 37 of this fan Fixture 30.One middle side part in this zone 25 is offered one and is used for the square draw-in groove 22 that button piece 392 with this fan Fixture 30 is interlocked.

The button hole 21 of this header board 20, clasp 23 and square draw-in groove 22 are snap hook 35, block button hole 37 and square button piece 392 corresponding settings that cooperate this fan Fixture 30.If the button piece 392 of this fan Fixture 30 is arranged to cylinder axis, the square draw-in groove 22 of header board 20 correspondingly can be set to circular groove.

Four corners of this fan 40 are provided with through hole 42.Plurality of fixed post 50 runs through the locking hole 32 of through hole 42 screw locks of this fan 40 at the substrate 31 of this fan Fixture 30, thereby this fan 40 is locked on this fan Fixture 30.

During assembling, this fan 40 is locked at this fan Fixture 30 by plurality of fixed post 50.By operating this operating body 39, snap hook 35 with this fan Fixture 30 pushes in the button hole 21 of this header board 20 earlier, the block button hole 37 of this fan Fixture 30 is snapped in the clasp 23 of header board 20, promote this fan Fixture 30 along F direction (referring to Fig. 1) then, when the snap hook 35 of fan Fixture 30 and the button hole 21 of header board 20, the clasp 23 of header board 20 hooks together mutually with the block button hole 37 of fan Fixture 30 and fixes back (as shown in Figure 4), press down the press part 393 of this operating body 39 again, this square button piece 392 is buckled in the square draw-in groove 22 of header board 20, promptly finish the assembling that the fan Fixture 30 that will fan 40 be housed is fixed on header board 20, as shown in Figure 3.

During dismounting, press part 393 by this operating body 39 of outside pulling, the square button piece 392 of this fan Fixture 30 is broken away from from the square draw-in groove 22 of this header board 20, then along the press part 393 of B direction (referring to Fig. 1) pull operation body 39, the snap hook 35 of this fan Fixture 30 is extracted out from the button hole 21 of header board, and the clasp 23 of the block button hole 37 of this fan Fixture 30 and this header board 20 is separated, thereby this fan Fixture 30 that fan 40 is installed is pulled down from this header board 20.
