BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is an exploded perspective view of a preferred embodiment of a fan fixture of the present invention.

2 is a perspective assembled view of FIG. 1.

Figure 3 is a partially enlarged view of the portion labeled III in Figure 2.

Please refer to FIG. 1 , which illustrates a preferred embodiment of a fan fixing device for fixing a fan 10 . The fan fixing device includes two fixing members 20 and a fixing plate 30.

The fan 10 includes a frame 12, an impeller 13 mounted at the center of the frame 12, and a plurality of blades 14 disposed on the periphery of the impeller 13. A plate body 121 is respectively disposed at the top and the bottom of the frame 12, and each of the plate bodies 121 is respectively provided with a fixing hole 123 adjacent to the four corners.

Each of the fixing members 20 includes an elongated body portion 21. The main body portion 21 includes an outer side wall 211 and an inner side wall 212 , and a first end portion 213 and a second end portion 214 . The outer sidewall 211 is respectively provided with a laterally extending groove 216 adjacent to the top and the bottom. A latching block 23 having a right-angled triangular cross section protrudes outwardly between the top of the outer sidewall 211 and the adjacent recess 216, and between the bottom and the adjacent recess 216. The two blocks 23 are adjacent to the first end 213 of the body portion 21. One side of each of the blocks 23 adjacent to the first end portion 213 has an abutting surface 231 perpendicular to the outer side wall 211, and a side away from the first end portion 213 is a sloped surface 233. The inner side wall 212 of the main body portion 21 is respectively provided with a pair of buckles 25 adjacent to the first end portion 213 and the second end portion 214. Each of the buckles 25 is provided with a leg 253, and the extending direction of the leg 253 of each pair of the buckles 25 is away from each other.

The fixing plate 30 is a side plate of a computer case in this embodiment. The fixing plate 30 is provided with a square heat dissipation region 31 formed by arranging a plurality of ventilation holes 311 corresponding to the fan 10. The fixing plate 30 is adjacent to each of the two opposite sides of the heat dissipation region 31. Two hooks 34 facing the heat dissipating area 31 and an elastic plate 35 are disposed on the straight line, and a baffle 36 is disposed adjacent to a middle portion of the other side of the heat dissipating area 31 connecting the opposite ends of the opposite sides. The two elastic plates 35 are respectively located at the other ends of the opposite sides.

2 and 3, when assembling, the two fixing members 20 are respectively fastened to opposite sides of the fan 10, so that the legs 253 of the two pairs of buckles 25 of each fixing member 20 are respectively engaged. The two plates 121 of the fan 10 are located in the two pairs of fixing holes 123 on the corresponding sides, and the blocks 23 of the two fixing members 20 are located at the same end of the fan 10. Then, the fan 10 and the fixing member 20 are slid between the two elastic plates 35 of the fixing plate 30 between the hooks 34 on both sides of the heat dissipation region 31. The hooks 34 are respectively inserted into the recesses 216 of the two fixing members 20 adjacent to the fixing plate 30, and the fan 10 slides along the hooks 34. In this process, the inclined surfaces 233 of the two clamping blocks 23 of the two fixing members 20 adjacent to the fixing plate 30 respectively abut against the two elastic plates 35 and push the two elastic plates 35 to elastically deform outward. When the fan 10 slides against the baffle 36 on the fixing plate 30, the two clamping blocks 23 completely pass over the two elastic plates 35 respectively, and the elastic plates 35 elastically recover and respectively resist the two clamping blocks 23. The fan 10 is fixed to the fixing plate 30 against the top surface 231.

When the fan 10 is removed, the two elastic plates 35 on the fixing plate 30 are pulled outwardly, so that the corresponding blocks 23 on the two fixing members 20 are respectively disengaged from the two elastic plates 35, so that The fan 10 is withdrawn.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. The above description is only the preferred embodiment of the present invention, and equivalent modifications or variations made by those skilled in the art will be included in the following claims.
