Fastener structure for securing multiple fans

Abstract

A fastener structure for securing multiple fans includes an assembly hole, a fastening pillar, and an adhesive layer. The assembly hole is located in a frame of a first fan. The fastening pillar is located on a frame of a second fan, wherein the configuration of the fastening pillar is suited to be inserted into the assembly hole. The adhesive layer is located between an outer wall of the fastening pillar and an inner wall of the assembly hole when the fastening pillar is inserted into the assembly hole.

What is claimed is: 
     
         1 . A fastener structure for securing multiple fans comprising:
 an assembly hole located in a frame of a first fan;   a fastening pillar located on a frame of a second fan, wherein the fastening pillar is configured to be fitted for and inserted into the assembly hole; and   an adhesive layer located between an outer wall of the fastening pillar and an inner wall of the assembly hole when the fastening pillar is inserted into the assembly hole.   
     
     
         2 . The fastener structure for securing multiple fans of  claim 1 , wherein a top of the fastening pillar has a barb member which is hooked to an inner surface of the frame of the first fan. 
     
     
         3 . The fastener structure for securing multiple fans of  claim 2 , wherein:
 the fastening pillar is hollow and has an arc-short wall and an arc-cylindrical plate, the arc-short wall being opposite to the arc-cylindrical plate, the barb member being formed at a top of the arc-cylindrical plate; and   the inner wall of the assembly hole forms an arc-short concave and an arc-retaining wall corresponding to the arc-short wall and an arc concave corresponding to the arc-cylindrical plate, the arc-short wall being coupled with the arc-short concave and the arc-retaining wall being coupled with the arc concave.   
     
     
         4 . The fastener structure for securing multiple fans of  claim 3 , wherein inner surfaces of the arc-retaining wall, the arc-short wall and the arc-cylindrical plate cooperatively form a circular inner wall.
