- Known technology for combining two or more fans to become one fan involves using fastener structures. Each of the fastener structures is composed of a connected member and two c-type fasteners. The c-type fasteners are used to connect the connected member and two unit fans such that the two unit fans are combined into a single fan assembly. The disadvantage of this configuration is that the connected member and the c-type fasteners are located in the inner portion of the fan frames after the fans are combined to each other such that the fans have a lower air transmission capability, thereby resulting in a reduction in overall fan efficiency.
- Therefore, there is a need to develop a fastener structure for securing multiple fans that is capable of avoiding the foregoing disadvantages.
- The present invention provides a fastener structure for securing multiple fans.
- In accordance with the present invention, 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, in which the fastening pillar is configured to be fitted for and 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. Through this configuration, the frame of the first fan is connected securely with the frame of the second fan.
- According to another embodiment disclosed herein, a top of the fastening pillar has a barb member which is hooked to an inner surface of the frame of the first fan for preventing the fastening pillar from being removed from the assembly hole.
- According to another embodiment disclosed herein, the fastening pillar is hollow and has an arc-short wall and an arc-cylindrical plate, in which the arc-short wall is opposite to the arc-cylindrical plate. The barb member is formed at a top of the arc-cylindrical plate. 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 is coupled with the arc-short concave and the arc-retaining wall is coupled with the arc concave. With this structure, the fastening pillar can be inserted into the inner of the assembly hole in a precise and secure manner.
- According to another embodiment disclosed herein, inner surfaces of the arc-retaining wall, the arc-short wall and the arc-cylindrical plate cooperatively form a circular inner wall, and a screw, bolt or other object can be inserted into and locked with the inner surfaces.
- Thus, the fastener structure herein secures multiple fans and does not affect the air flow generated by the fans.

As shown inFIGS. 1-4 , thefastener structure 300 for securing multiple fans is used to combine afirst fan 100 with asecond fan 200 which form the combination fan. Thefastener structure 300 includes fourassembly holes 310, fourfastening pillars 320, in which each of thefastening pillars 320 is configured to be fitted for and inserted into one of theassembly holes 310, andadhesive layers 330 each located between an outer wall of one of thefastening pillars 320 and an inner wall of one of theassembly holes 310. - In this embodiment, a size of the
first fan 100 is 40×40×28 mm and thefirst fan 100 has aframe 110. Theframe 110 is rectangular and one or more motors andblade units 120 are included within theframe 110 of thefirst fan 100. A size of thesecond fan 200 is 40×40×28 mm and thesecond fan 200 also has aframe 210. Theframe 210 is rectangular and one or more motors andblade units 220 are included within theframe 210 of thesecond fan 200. - The
assembly holes 310 are respectively located in four corners of theframe 110 of thefirst fan 100. Thefastening pillars 320 are respectively located in four corners of theframe 210 of thesecond fan 200. The fouradhesive layers 330 are located between the outer walls of the four fasteningpillars 320 and the inner walls of the fourassembly holes 310. The fourfastening pillars 320 of thesecond fan 200 are respectively inserted into the fourassembly holes 310, and the fourfastening pillars 320 respectively adhere to the fourassembly holes 310, such that thefirst fan 100 is combined with thesecond fan 200 to form the combination fan. In this embodiment, the size of the combination fan is 40×40×56 mm. - The
assembly holes 310 are formed directly in theframe 110 of thefirst fan 100, and thefastening pillars 320 are formed directly with theframe 210 of thesecond fan 200. Theadhesive layers 330 are used to securely combine thefastening pillars 320 of theframe 210 of thesecond fan 200 respectively in theassembly holes 310 of theframe 110 of thefirst fan 100. Therefore, the fastener structure is simple, as is the method for using the same. Because thefastening pillars 320 of theframe 210 of thesecond fan 200 are securely combined with theassembly holes 310 of theframe 110 of thefirst fan 100, almost no vibration is generated by the combinedframes 110/210 when the combination fan (of thefirst fan 100 and the second fan 200) is operating. In addition, thefastener structure 300 is located in the four corners of theframes 100/210 and is not located within theframes 100/210 such that thefastener structure 300 does not negatively affect the air transmission of theblade units 120/220. - Each of the
fastening pillars 320 is a hollow pillar and includes an arc-short wall 321 and an arc-cylindrical plate 322, in which the arc-short wall 321 is opposite to the arc-cylindrical plate 322. The inner wall of each of theassembly holes 310 forms an arc-short concave 311 corresponding to the arc-short wall 321 of thecorresponding fastening pillar 320, an arc-retaining wall 312 and an arc concave 313 corresponding to the arc-cylindrical plate 322 of thecorresponding fastening pillar 320. When thefirst fan 100 is combined with thesecond fan 200, each of the arc-short walls 321 of thefastening pillars 320 of thesecond fan 200 is coupled with the arc-short concave 311 of thecorresponding assembly hole 310 of thefirst fan 100 and each of the arc-cylindrical plates 322 of thefastening pillars 320 of thesecond fan 200 is coupled with the arc concave 313 of thecorresponding assembly hole 310 of thefirst fan 100, in which each of the are-short walls 321 abuts against the arc-retaining wall 312 of thecorresponding assembly hole 310, such that each of thefastening pillars 320 is located securely and precisely within one of theassembly holes 310. After thefirst fan 100 is completely combined with thesecond fan 200, the inner surfaces of the arc-retaining walls 312, the arc-short walls 321 and the arc-cylindrical plates 322 cooperatively form circular inner walls, which may be used for insertion and locking of objects, e.g., screws or bolts. - The top of the arc-
cylindrical plate 322 of each of thefastening pillars 320 forms abarb member 323, and thebarb member 323 is hooked to an inner surface of theframe 110 of thefirst fan 100 to prevent thefastening pillar 320 from being removed from thecorresponding assembly hole 310 when thefastening pillar 320 of thesecond fan 200 is inserted into theassembly hole 310 of thefirst Can 100. - According to above-described embodiments, the fastener structure herein secures multiple fans securely and does not adversely affect the air flow generated by the combined fans.
