Description

Fan fixing structure

The present invention is a fan fixing structure, which is a structure that is fastened and detached by means of an inlay fastening method.

According to the conventional heat sink device, as shown in FIG. 1 , the structure is a board 100 , which may be a display card, a central processing unit (CPU) or a light-emitting diode (LED) base. An opening 110 is disposed on the board 100. The opening 110 is respectively provided with two opposite screw holes 120, and the opening is provided with a fan body 200. The fan body 200 is respectively provided with a through hole 210 at the periphery thereof. The through holes 210 are respectively opposite to the screw holes 120. When assembled, the screw 300 passes through the through holes 210 and is locked in the lock hole 120 to fix the fan body 200 on the board 100. Otherwise, when disassembling The screw 300 must be loosened from the screw hole 120 by the tool, so that the fan body 200 can be disassembled and cannot be assembled or disassembled quickly. Moreover, because the space of the machine board 100 is very limited, it often happens that the tool cannot penetrate into the environment and is in use. Very unsatisfactory.

In addition, another conventional device is the Taiwan Patent No. M397135, which includes a pedestal 400. The pedestal 400 is provided with an accommodating space 401, and an air outlet 402 is disposed at the bottom of the accommodating space 401. A fan 403 is disposed on the edge of the space 401. The fan 550 is disposed in the accommodating space 401. When assembled, the fan 500 is placed in the accommodating space 401. The 403 is fastened to the edge of the fan 500, and the fan 500 is fixed therein. The device 500 can be fixed by the tool without the use of a tool, but the protruding portion of the latch 403 is open in the accommodating space 401. On the edge, when the fan 500 is to be placed therein, the card 403 needs to be pulled outwards, otherwise the fan 500 will be blocked and cannot enter the accommodating space, which may easily cause injury or other accidents.

Creation outline:

The creator of this case has the above-mentioned shortcomings when installing the fan. Therefore, it is aimed at the crux of the problem and began to seek improvement and make up for it. In order to seek a reasonable solution, after countless After the second analysis, design, finally completed the fan fixed structure of this creation.

One of the purposes of this creation is to provide a simple fan fixing structure that is easy to install and disassemble.

Another purpose of this creation is to provide the cost of working hours for the assembly of personnel.

The technical means for achieving the above object includes a fan fixing structure, which is a structure for fixing a heat dissipating fan on a base. The structure is provided with a fan body, and the lower end of the fan body is respectively provided with more than one. In the inlay, the base is provided with an opening for accommodating the fan body, and the edge of the opening is respectively provided with a matching groove for the inlay. When assembling, the fan body is first placed in the opening, so that the inlay of the fan body enters. The guiding portion, by changing the position, causes the inlay to slide into the fixing portion, and is restricted by the fixing portion, so as not to sway to the left and right, thereby achieving the function of fixing the fan body. Conversely, when disassembling, only the inlay is moved to the guide. The lead portion is used to disengage the inlay from the slot.
