Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Please refer to Fig. 1 to Fig. 3, the preferred embodiments of fan fixer of the present invention, can fix some fans 20.This fan fixer comprises a fan board 10, two mounting rods 30 and eight blinkers 40.
Each fan 20 comprises two relative side plates 21.The Si Jiaochu of every side plate 21 is respectively equipped with a fixing hole 213.
This fan board 10 comprises a microscler base 12 and the microscler fixation wall 14 being extended to form vertically upward by the posterior lateral margin of this base 12.These fixation wall 14 along continuous straight runs compartment of terrains are provided with four-way air port 141, and the surrounding of each ventilating opening 141 is provided with four-way hole 143.The two ends of this fixation wall 14 be all convexly equipped with forward first connecting portion 145 and that is positioned at top be positioned at middle part the second connecting portion 147.Each first connecting portion 145 is provided with one first perforation 146 towards another first connecting portion 145.Each second connecting portion 147 is provided with one second perforation 148 towards another second connecting portion 147.
Each mounting rod 30 is made up of plastic material.Each mounting rod 30 contiguous two ends place is respectively equipped with a circle projection 31 along periphery.
Each blinker 40 comprises a rectangular main part 41 and is convexly set in the pivot part 43 of some C shapes with opening 431 separately at these main part 41 tops.Coaxial and the opening 431 of these pivot parts 43 towards identical.
While assembling a fan 20, the side plate of this fan 20 21 is posted by the rear side of this fixation wall 14, makes four fixing holes 213 of this side plate 21 respectively just to the four-way hole 143 around a wherein ventilating opening 141 of this fixation wall 14.By four locking parts, respectively through this four-way hole 143 and be locked in this four fixing hole 213, just this ventilating opening 141 be fixed on to this fixation wall 14 by this fan 20 as screw or buckle.User, according to radiating requirements, can just install respectively a fan 20 to each ventilating opening 141 at the rear side of this fixation wall 14, or just some ventilating opening 141 is wherein installed respectively to a fan 20.
Assemble this two mounting rod 30.This two mounting rod 30 is bent to distortion, make the wherein two ends of a mounting rod 30 aim at respectively first perforation 146 at these fixation wall 14 two ends, and make the two ends of another mounting rod 30 aim at respectively second perforation 148 at these fixation wall 14 two ends.Decontrol this two mounting rod 30, make the two ends of each mounting rod 30 snap in respectively two first corresponding perforation 146 or two second corresponding perforation 148.Now, these two mounting rods, 30 levels, two projections 31 difference blocks of each mounting rod 30 are in the inner side of two first connecting portions 145 of correspondence or two second connecting portions 147 of correspondence.Thereby this two mounting rod 30 is fixed in this fixation wall 14.
On each mounting rod 30, install pivotally four blinkers that connect successively 40.While assembling each blinker 40, make the opening 431 of the pivot part 43 of this blinker 40 aim at corresponding mounting rod 30.Push pivot part 43 to this mounting rod 30, pivot part 43 strains open opening 431 until this mounting rod 30 is contained in pivot part 43.Pivot part 43 elasticity are recovered opening 431 is dwindled, and can not come off from corresponding mounting rod 30 when guaranteeing that blinker 40 rotates.These blinker 40 gravitates keep vertically, and the front side of each ventilating opening 141 of this fixation wall 14 is covered completely by two blinkers 40 that distribute up and down.
When fan 20 turns round, before fan 20 blows out the distinguished and admirable corresponding ventilating opening 141 through this fixation wall 14 is backward, blow the blinker 40 that is positioned at fan 20 dead aheads, make the blinker 40 in fan 20 dead aheads rotate forward and upwards 90 degree around corresponding mounting rod 30, do not affect the air-out of fan 20.
If while having fan 20 to stop operating because of fault, blinker 40 gravitates of these fault fan 20 front sides keep vertically, can stopping the distinguished and admirable of backflow.
If the rear side of some ventilating openings 141 is not when provided with fan 20, blinker 40 gravitates of these ventilating opening 141 front sides keep vertically, also can stopping the distinguished and admirable of backflow.
