Description

Fan fixture

The present invention relates to a fan fixing device.

In the prior art, a fan is usually fixed by screws to the base of the server chassis, and then the upper cover is closed to block the top of the fan. It is very cumbersome to lock in and release the screws when disassembling the fan.

In view of the above, it is necessary to provide a fan fixing device that facilitates the disassembly and assembly of a fan.

A fan fixing device includes a fan, a chassis and two card firmware. The fan includes an end plate. The chassis includes a base. The base includes a bottom plate and a fixing plate vertically disposed on the bottom plate. The fixing plate is provided with a fixing plate. a venting port, wherein the fixing plate is respectively provided with an L-shaped hook bent toward the venting opening on the two sides of the venting opening, and the two fastening members are respectively rotatively clamped on two sides of the end plate of the fan, each One side of the fastener facing away from the other fastener is provided with a flange, and the two flanges are respectively inserted between the two hooks and the fixing plate, and the fan support is fixed on the bottom plate.

Compared with the prior art, the fan fixing device can conveniently fit the fan into the base of the chassis by inserting or sliding the two fasteners mounted on the two sides of the fan between the two hooks and the fixed plate. The fan is conveniently removed from the base for quick and easy operation.

Referring to FIG. 1 and FIG. 3 , a preferred embodiment of the fan fixing device of the present invention includes a fan 10 , a chassis 20 , and two fasteners 30 .

The rear end of the fan 10 is provided with an end plate 12. A fixing hole 121 is respectively defined at four corners of the end plate 12.

The chassis 20 includes a base 21 and an upper cover 23 that is covered by the base 21 . The base 21 includes a bottom plate 212 and a fixing plate 213 vertically disposed on the bottom plate 212. The fixing plate 213 is provided with a vent 215. The fixing plate 213 is respectively provided with an L-shaped hook 216 bent to the vent 215 on both sides of the vent 215.

Each of the fasteners 30 includes an elongated plate body 31, a first baffle 32 extending perpendicularly from one end of the inner side rear edge of the plate body 31, and a rear side edge of the inner side of the plate body 31. a second baffle 34 extending perpendicularly from the other end, two third baffles 36 extending perpendicularly from opposite ends of the inner side edge of the inner side of the plate body 31, and a rear side edge of the outer side of the plate body 31 An elongated flange 38 extends vertically. The inner side of the first baffle 32 (ie, the side facing the two third baffles 36) is provided with a hemispherical convex hull 321 . A protrusion 361 is disposed away from an inner side of the third baffle 36 of the first baffle 32 (ie, a side facing the first baffle 32). The protrusion 361 and the second baffle 34 are offset from the longitudinal direction of the fastener 30 and are located on a side of the second baffle 34 away from the first baffle 32.

When assembled, the inner sides of the two fasteners 30 are opposed to each other. The two fasteners 30 are respectively disposed on two sides of the end plate 12 of the fan 10. The protrusions 361 of each of the fasteners 30 correspond to a fixing hole 121 of the end plate 12. Each of the fasteners 30 is rotated horizontally in a direction away from the fan 10 by the protrusion 361 of the fastener 30, and the fastener 30 is moved to pass the protrusion 361 of the fastener 30 from the front to the rear through the end plate. Corresponding fixing hole 121 of 12. Rotating the two fasteners 30 with the two protrusions 361 as the axial direction, respectively, so that the two sides of the end plate 12 of the fan 10 are respectively placed on the third baffle 36 of the corresponding fastener 30 and the first Between the second baffles 32, 34. When the convex 321 of the first baffle 32 of each of the fasteners 30 abuts against the rear side of the end plate 12 of the fan 10, the first baffle 32 is pushed to be elastically deformed backward until the convex ridges 321 of the two fasteners 30 are respectively positive. When the other two vacant fixing holes 121 of the end plate 12 are detached, the two first baffles 32 are elastically restored, so that the two convex hulls 321 are respectively engaged with the corresponding fixing holes 121. Thus, the two fasteners 30 are respectively fixed to both sides of the end plate 12.

Referring to FIG. 2 together, the fan 10 is placed above the fixing plate 213 of the base 21 such that the flanges 38 of the two fasteners 30 respectively face the tops of the hooks 216 on both sides of the vent 215. The fan 10 is moved downwardly to the bottom of the fan 10 to abut the bottom plate 212, so that the flanges 38 of the two fasteners 30 are respectively caught between the two hooks 216 and the fixing plate 213. The fan 10 is fixed in the base 21 in the front, rear, left, and right directions. The upper cover 23 of the casing 20 is covered, and the upper cover 23 is blocked at the top of the fan 10, so that the fan 10 can be completely fixed.

In other embodiments, the convex hull 321 of each of the fasteners 30 may be disposed not on the first baffle 32 but on the inner side of a third baffle 36 adjacent to the first baffle 32.

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention.
