Mounting device for fan

Abstract

A mounting device for a fan includes a bottom wall and a base for supporting the fan. The bottom wall forms two rods. The base includes a plate and two fixing pieces extending out from opposite sides of the plate. Each fixing piece defines a fixing hole through which a corresponding one of the rods extends.

What is claimed is: 
     
         1 . A mounting device for mounting a fan having two opposite boards, comprising:
 a base comprising a plate for supporting the fan, and two fixing pieces extending from opposite sides of the plate, each fixing piece defining a fixing hole; and   a bottom wall forming two rods each engaged in a corresponding one of the fixing holes.   
     
     
         2 . The mounting device of  claim 1 , further comprising two fasteners, wherein two first protrusions extend up from a first side of the plate, two second protrusions extend up from a second side of the plate, opposite to the first side, each first protrusion defines a through hole, each second protrusion defines a threaded hole, the fasteners extend through the corresponding through holes and the boards of the fan to engage in the corresponding threaded holes. 
     
     
         3 . A fan assembly, comprising:
 a fan comprising two opposite boards;   a base comprising a plate supporting the fan, and two fixing pieces extending from opposite sides of the plate, each fixing piece defining a fixing hole; and   a bottom wall forming two rods each engaged in a corresponding one of the fixing holes.   
     
     
         4 . The fan assembly of  claim 3 , further comprising two fasteners, wherein two first protrusions extend up from a first side of the plate, two second protrusions extend up from a second side of the plate, opposite to the first side, each first protrusion defines a through hole, each second protrusion defines a threaded hole, the fasteners extend through the corresponding through holes and the boards of the fan to engage in the corresponding threaded holes.
