Description

Fan fixer

The utility model is about a kind of fan fixer, refer in particular to a kind ofly install and remove conveniently, in conjunction with firm fan fixer.

More and more wide along with the fast development of computing information industry and range of application thereof, the rate request of the computer internal electronic element being handled data is also more and more high, be accompanied by the raising of travelling speed, the heat that associated electronic components produces also rolls up, if it is untimely with this heat discharge, therefore stability and quality during with the influence operation must adopt the heating radiator with fan to be combined as this type of electronic element radiating.

The combination of fan of the prior art and heating radiator adopts screw directly to lock mostly, as shown in Figure 1, four corners of this fan 2 are respectively equipped with a fixed orifice, this heating radiator 1 is forming screw thread respectively to position that should fixed orifice, passes this fixed orifice and locks mutually and fan 2 is fixed on the heating radiator 1 with screw thread on the heating radiator 1 by screw 3.But this mode of utilizing screw 3 to fix is quite inconvenient, and need utilize specific instrument just can finish mounting or dismounting in addition.And, when screw 3 locks mutually with heating radiator 1, can produce some aluminium bits, influence the outward appearance of product, even heating radiator 1 is caused damage.In addition, the mode of this fan attachment 2 of the prior art can only be used for the heating radiator 1 of specific dimensions and structure, does not have versatility.

The fan fixer that the purpose of this utility model is to provide a kind of to be installed and removed conveniently, combination is firm and have good versatility.

For achieving the above object, the utility model has adopted following technical scheme: the utility model fan fixer comprises loam cake, fan and lower cover.Four corners of this fan are respectively equipped with circular fixed orifice.These loam cake central authorities are formed with the through hole of corresponding fan dimension, further form recess respectively in the both sides of the edge of through hole.The bottom surface of this loam cake is respectively equipped with fixed leg in the position of corresponding fan four corner fixed orifices.The base portion of this lower cover is also corresponding in the position of corresponding fan four corner fixed orifices to be provided with the perforation that the fixed leg that is used for loam cake fastens.Be formed with the air vent of corresponding fan dimension on this base portion, and on a counter-lateral quadrents corresponding to loam cake recess position the corresponding respectively fixed head that extended upward, the top of each fixed head convexes with outwardly and is used for and the recess of the loam cake snap hook of buckle mutually.Extend upward lug respectively on another counter-lateral quadrents of this base portion, this lug be used for against the opposite flank of fan and limit lower cover and fan between lateral slip.

Compared with prior art, the utility model fan fixer utilizes the direct snapping heating radiator of lower cover, and utilizes the buckle between loam cake and lower cover and fix fan, so integral installation is quite convenient.And when the heating radiator of collocation use changed on size or structure to some extent, it is promptly applicable that the utility model only need be changed lower cover, therefore has good versatility.In addition, the utility model has also avoided the screw of the prior art mode that directly locks can influence product appearance, even heating radiator is caused the deficiency of damage, and easy accessibility, in conjunction with firmly.

Below in conjunction with accompanying drawing embodiment of the present utility model is specifically described:

Fig. 1 is the three-dimensional exploded view of fan of the prior art, heating radiator and screw.
