Fixing device for fan
View Patent ↗A device for fixing two fans includes a chassis, a limiting member mounted in the chassis, and a blocking member. A receiving space is bounded by the chassis and by the limiting member. The blocking member is sandwiched between the fans, and includes two angled plates which may concertina towards or away from each other as the fans are repositioned to seal the space between the fans.
1. A fixing device for fixing a plurality of fans, the fixing device comprising:
a chassis;
a limiting member formed in the chassis, and bounding a receiving space together with the chassis; and
a blocking member for being sandwiched between adjacent two of the plurality of fans, the blocking member comprising two angled plates, first ends of the plates connected to each other, and second ends of the plates connected to the two fans, respectively;
wherein the plates are operable to extend toward or away from each other in response to the two fans moving toward or away from each other, to fill a space between the fans.
2. The fixing device of claim 1 , wherein the chassis comprises a bottom wall and two sidewalls extending up from opposite sides of the bottom wall, the limiting member is mounted between the sidewalls, and comprises a top board opposite to the bottom wall.
3. The fixing device of claim 2 , wherein the top board defines a slot perpendicular to the sidewalls for manipulate the position of the fans.
4. The fixing device of claim 3 , wherein the top board defines an opening adjacent to one of the sidewalls, through which the fans enter the receiving space.
5. The fixing device of claim 2 , wherein the limiting member further comprises two side boards extending down from opposite sides of the top board, the side boards sandwich tops of the fans.
6. The fixing device of claim 5 , wherein two blocking pieces substantially perpendicular to the sidewalls extend in a substantially perpendicular manner from the bottom wall to sandwich bottoms of the fans.
7. The fixing device of claim 6 , further comprising a plurality of fasteners, wherein each fastener comprises a head and an extension portion extending from a first side of the head, wherein the extension portions extend through the fixing pieces and engage in the fans, the second sides of the heads opposite to the first sides resist against inner surfaces of the blocking pieces and the side boards, correspondingly.
8. The fixing device of claim 2 , wherein the plates are perpendicular to the bottom wall.
9. The fixing device of claim 1 , wherein the blocking member is substantially V-shaped, a fixing piece extends from the second end of each plate away from the other plate, to be fixed to the corresponding fan.
10. The fixing device of claim 1 , wherein the blocking member is made of elastic material, and is operable to be twisted.
