Vibration Proof Structure Of Fan

Abstract

A vibration proof structure of a fan is provided. The vibration proof structure includes a frame, a plurality of buffer members, and a plurality of rigid rods. The frame is adapted for assembling with a blade assembly. The buffer members are assembled to the frame. The rigid rods are assembled inside the buffer members, respectively. Each of the rigid rods comprises an axially penetrated through hole. After the fan is secured to the object to which the fan is desired to be assembled, the vibration caused in the operation of the fan can be effectively absorbed by the buffer members, and thus the noises can be eliminated.

1 . A vibration proof structure of a fan, comprising:
 a frame, adapted for assembling with a blade assembly;   a plurality of buffer members, assembled to the frame; and   a plurality of rigid rods, assembled inside the buffer members, respectively, wherein each of the rigid rods is configured with an axially penetrated through hole.   
     
     
         2 . The vibration proof structure according to  claim 1 , wherein a plurality of secure grooves are configured at a periphery of the frame, and the buffer members are assembled inside the secure grooves, respectively. 
     
     
         3 . The vibration proof structure according to  claim 2 , wherein the secure grooves are dove-tail grooves. 
     
     
         4 . The vibration proof structure according  claim 3 , wherein the buffer members are made of a resilient material. 
     
     
         5 . The vibration proof structure according to  claim 4 , wherein each of the secure grooves is configured with a protrusion rib having a through hole, and the buffer members are formed inside the secure grooves and enclosing the protrusion ribs by executing a molding process. 
     
     
         6 . The vibration proof structure according to  claim 1 , wherein a flection member is configured at an outer surface of each of the rigid rods, and the flection member and the outer surface are enclosed by the buffer members.
