Description

Fan Fixture

The utility model be meant especially about a kind of fan Fixture a kind of simple in structure and make things convenient for the fan Fixture of fan mounting or dismounting.

In personal computer, main pyrotoxin is the central processing unit on the motherboard, and this central processing unit is located at a side of the inner contiguous power supply unit of computer case usually, utilizes the fan of power supply unit to discharge the heat that central processing unit produces simultaneously., speed higher at frequency is central processing unit faster, the heat of its corresponding generation is more, in order to reach effective radiating effect, on the front or rear panel of computer case, further be equiped with second fan, discharge cool exterior air is sucked in the computer case and, thereby realize better radiating effect by the fan of power supply unit.Existing second fan mostly is to utilize screw to fix, quite inconvenience of mounting or dismounting under the condition of limited of computer case inner space, and time and effort consuming again, when utilizing instrument locking screw such as turnscrew, also might damage other assemblies such as motherboard.

Existing another kind is fixed the mode of second fan, can be No. the 82209882nd, Taiwan patented claim with reference to Figure 1 and Figure 2, and it discloses a kind of computer fan fixed sturcture, comprises that mainly rectangle button fixing support body 1 and small-sized fans hold shell 3.This fixing support body 1 is to be fixed on the computer rack side arm wall 7, and which is provided with the honeycomb hole 2 of arranged; This small-sized fans holds shell 3 can hold embedding one small-sized fans 6 in wherein, which is provided with overhanging symmetric figure overhead kick 5,, in addition, establishes a cover plate 4 and small-sized fans is held shell 3 covers on the hole 2 of fixing support body 1 with hook.But this fan fixed structure is quite complicated, and palpus consideration computer rack side arm wall 7, fixing support body 1 and fan hold the hook of 3 on shell to be fixed, and when mounting or dismounting fan 6, needs also to consider together that this fan holds shell 3 and cover plate 4, very inconvenient on operating.

It is a kind of simple in structure and be convenient to the fan Fixture of fan mounting or dismounting that the purpose of this utility model is to provide.

For achieving the above object, the utility model has adopted following technical proposals: the utility model fan Fixture is to be formed by the bending of sheet metal one stamping-out, and its central authorities have a manhole.Outer rim at this through hole, this fan Fixture is with around this through hole mode all around, extend a pair of first bent sheet in regular turn, one banking stop, one second bent sheet and a shell fragment, wherein, should be vertically to extend and be arranged in a linear each other to first bent sheet, this second bent sheet is vertically to extend and parallel relative to first bent sheet with this, this banking stop is vertically to extend, be located between this first bent sheet and second bent sheet and perpendicular to first bent sheet and second bent sheet, this shell fragment is slightly outstandingly to extend and relative with banking stop towards this banking stop cantilever.In addition, this fan Fixture is provided with a blind rivet hole between this is to first bent sheet, and is respectively equipped with a button hole in two corners, the outside of this second bent sheet.

Owing to adopted technique scheme, the utility model not only can reduce aided processes such as lock screw, and had advantage simple in structure, that the fan mounting or dismounting are convenient.

In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.

Fig. 1 is the three-dimensional exploded view of existing fan Fixture and associated component.

Fig. 2 is the three-dimensional combination figure of existing fan Fixture and associated component.

Fig. 3 is the three-dimensional exploded view of the utility model fan Fixture and associated component.

Fig. 4 is the three-dimensional combination figure of the utility model fan Fixture and associated component.

See also Fig. 3, this fan Fixture 10 is to be fixed on header board, back plate or the side plate of computer case with blind rivet 30 installings, fixes a fan 50 simultaneously, and following is that example is done explanation with header board 40 only.

This fan Fixture 10 is to be formed by the bending of sheet metal one stamping-out, and its central authorities have a manhole 12.Outer rim at this through hole 12, this fan Fixture 10 is towards the direction in contrast to computer case header board 40, with around this through hole 12 mode all around, extend a pair of first bent sheet 14 in regular turn, one banking stop 16, one second bent sheet 15 and a shell fragment 18, wherein, should be vertically to extend and be arranged in a linear each other to first bent sheet 14 from fan Fixture 10, this second bent sheet 15 is vertically to extend and parallel relative to first bent sheet 14 with this from fan Fixture 10, this banking stop 16 is vertically to extend from fan Fixture 10, between this first bent sheet 14 and second bent sheet 15 and perpendicular to first bent sheet 14 and second bent sheet 15, this shell fragment 18 is slightly outstanding towards this banking stop 16 cantilevers extension and relative with banking stop 16 from fan Fixture 10.In addition, this fan Fixture 10 is provided with a blind rivet hole 22 between this is to first bent sheet 14, and is provided with a button hole 24 in addition at two corners, the outside of this second bent sheet 15 branch.

The extending end of this first bent sheet 14 further vertically extends a catch 26 inwardly, to limit fan 50 on the thickness direction of fan 50.This first bent sheet 14 is slightly extended a fairlead 28 towards outer incline at the lateral margin towards shell fragment 18, in order to the installing (in detail referring to aftermentioned) of guiding fan 50.Similarly, also extend a vertical catch 27 and a fairlead 29 that omits towards outer incline inwardly on this second bent sheet 15.

As previously mentioned, this banking stop 16 is perpendicular to first bent sheet 14 and second bent sheet 15, by first bent sheet 14, second bent sheet 15 and banking stop 16 jointly frame firmly limit fan 50 in wherein.

Should extend and the shell fragment 18 relative with banking stop 16 towards banking stop 16 cantilevers from fan Fixture 10 is slightly outstanding, be to extend towards banking stop 16 first slight inclination are outstanding, afterwards horizontal-extending again.

This computer case header board 40 is provided with some air vents 42 that are radial arrangement in the position corresponding to fan Fixture 10 manholes 12, offering a circular hole 46 corresponding to the position in fan Fixture 10 blind rivet holes 22, and be provided with two clasps 44 in position corresponding to 10 liang of button holes 24 of fan Fixture.

Please together with reference to figure 4, during assembling, earlier the clasp 44 of header board 40 button hole 24 with fan Fixture 10 is interlocked, passes the circular hole 46 of the blind rivet hole 22 of fan Fixture 10 and header board 40 and reach combination with blind rivet 30 again, be fixed on the header board 40 and fan Fixture 10 is installed.Afterwards, with fan 50 by shell fragment 18 places of this fan Fixture 10 and in the situation of depressing shell fragment 18 glides fan fixed mount 10, by first bent sheet 14, second bent sheet 15 and corresponding fairlead 28,29 guide slipping into of fan 50, be resisted against banking stop 16 up to first side 52, the place ahead of this fan 50 and promptly finish assembling, second side 54, rear of this fan 50 was slided just and was crossed this shell fragment 18 this moment, the then up resilience and prop up second side 54, rear of fan 50 and limit fan 50 and avoid oppositely skidding off with its cantilever free end under the elastic force effect of this shell fragment 18.

During dismounting, depress this shell fragment 18 and fan 40 is withdrawed from and can finish.
