Description

Fan frame quakeproof fixing mechanism

Technical field

The present invention relates to a kind of fixed mechanism, in detail, relate to a kind of for fan frame quakeproof fixing mechanism.

Background technique

Central arithmetic processor now is more and more faster, periphery is equipped with also more and more, the heat that whole computer came out is more high than in the past, but, the shared space of casing is but wished more and more littler, in order to realize user's demand, so casing inside mostly is equiped with fan at present, the casing that forces environment space to be limited to the method for forced convection is dispelled the heat fast.

But, in casing, be equiped with the influence that fan then can make integral body be vibrated, reach resonance phenomenon if therefore cause casing and fan to rotate the vibrations that produced, make easily that then the electronics zero element is damaged, especially for example the such storage device of hard disk, the as easy as rolling off a log disk of read head scratch hard disk that causes because of the vibrations that produce when moving causes bad rail to produce, therefore lost significant data, if this electronic equipment is then just very serious because of shaking the loss that is caused for example in order to handle the network host of a large amount of Financial Informations.

Therefore, though have fan to add the design of shock absorbing apparatus in casing inside, the influence that vibrations caused during in order to the attenuating fan running, existing shock absorbing apparatus be when fan is anchored in the casing, add Upper gasket or elastic component in fan and casing surface of contact to cushion the transmission of its vibrations, but effect is limited, if need the installing number of fans more, the effect of its generation then more can not reach requirement, therefore, for addressing the above problem, so the generation of fan board and shock-absorbing design is arranged, solve the problem that needs to install a plurality of fans and shock-absorbing in the lump, but this fan board is to combine in the fastening mode of screw with the shock-absorbing circuit elements design, if be used for a large amount of when making and producing, very inconvenience and labor intensive, also wasted the fastening required space of operation tool, relative can't save the space, also can't reach the demand of present reduced volume.

Therefore, the shock absorbing apparatus in the time of how designing the fan assembling makes it can take into account incabloc function, can cooperate the global design of casing inside again, and make the user easy to operate, can exempt from tool operation again, promptly becomes the important topic that needs to be resolved hurrily in the design.

Summary of the invention

In view of the shortcoming of above-mentioned prior art, one object of the present invention is to provide a kind of fan frame quakeproof fixing mechanism, thereby makes fan board be easy to the fixing influence that also can reduce the fan vibrations.

Another object of the present invention is to provide a kind of fan frame quakeproof fixing mechanism, thereby can not need instrument to install, to reach the effect of convenient operation.

For achieving the above object and other purposes, the invention provides a kind of fan frame quakeproof fixing mechanism, its in order in conjunction with fan board in the first set buckling part of casing, this fan frame quakeproof fixing mechanism comprises: connecting part, its symmetry are convexly set in the face that is provided with of these fan board both sides; Locating support has second buckling part, reaches perforation, and this second buckling part can be fastened on first buckling part on the casing, and this perforation wears for the connecting part; Elastic component, it is located between connecting part and the perforation and extends to this locating support with respect to these both sides of boring a hole; And conjunction, it is for being bonded to this connecting part and locating the side of this elastic component away from fan board, to fix the positioning relation of this locating support and this fan board.

And in the fan frame quakeproof fixing mechanism of the invention described above, this is symmetrically formed in the connecting part of this fan board dual-side, its the axial direction profile groove be beneficial to conjunction insert in conjunction with the time deformation, wherein, this connecting part offers for conjunction and penetrates the groove that folder is established, wherein, this conjunction is selected from wherein one of rubber, plastics, timber and metal, in one embodiment, this conjunction can be the form of Fixed latches, this Fixed latches has pin portion and clamping part, can push and insert the fixing effect of connecting part reinforcement.

In the aforementioned fan frame quakeproof fixing mechanism of the present invention, this conjunction also is provided with a bulge loop in the pin portion outside, thereby pass the groove of connecting part with bulge loop when should pin portion inserting the connecting part and be fastened on the fan board, for fixing the location and keep the positioning relation of fan board and locating support, and can by the clamping part be arranged on assembling the time energy easy operating.In addition, this connecting part penetrates has the set perforation of elastic component, simultaneously between the clamping part of this Fixed latches and locating support this elastic component of clamping away from a side of fan board, thereby can make vibrations that fan board transmits through the clamping part of conjunction and the effect that further reaches horizontal damping that contacts of elastic component, and the connecting part of this fan board is arranged in perforation and accompanies on the locating support of elastic component, the better axial shock insulation and the effect of location can also be provided, wherein, the elastic component of this locating support is selected from elastomeric plastics, reed, wherein one of spring, in a preferred embodiment, this elastic component is an elasticity of plastics spare, thereby the perforation that makes locating support provides the connecting part of fan board better locating effect, also has the function of shock insulation between fan board and casing and electronic circuit component simultaneously.

And above-mentioned locating support, it comprises second buckling part that is installed on the casing with the fan attachment frame, and by this second buckling part for butt and fasten first buckling part that casing is convexly equipped with, with moving of restriction locating support, and has an easy-disassembling-assembling convenience, wherein, this second buckling part is an arc-shaped through-hole, the screw that first buckling part of this casing fastens for second buckling part, in the gap that is snapped in the formation of this screw and casing by this arc-shaped through-hole, in one embodiment, this is arranged at the fan board both sides and has arc-shaped through-hole with the butt casing in order to second buckling part of a side locating support of fan attachment frame, and in a side of relative fixed fan board, second buckling part of this locating support then can be the framework of a fastening machine shell-side edge, to engage the positioning element that the casing lateral margin is convexly equipped with, preferably, this locating support is when the fan board of location, it has the perforation that inner ring is established elastic component, connecting part for fan board penetrates the set perforation of this elastic component, and engaging has conjunction on this connecting part, again the framework of this locating support is fastened on first buckling part of casing lateral margin, thereby reaches the location at fan board two ends and the effect of shock insulation simultaneously.

Therefore, fan frame quakeproof fixing mechanism of the present invention can wear by the connecting part of this fan board into having elastic component and be located on locating support in the perforation inner edge so that fan board location, and wear and be fastened in by conjunction and reach the effect of strengthening the fan board location on the connecting part, utilize the connecting part again, the Elastic Contact of conjunction and elastic component, so that the effect of shock-absorbing to be provided, therefore, fan frame quakeproof fixing mechanism of the present invention, make fan board be easy to the fixing influence that also can reduce the fan vibrations, and tool free is installed, effect with convenient operation satisfies user's demand, and solves the existing in prior technology problem.
