Description

fan mount

technical field

The invention relates to a fan fixing device.

Background technique

The existing fan is usually screwed into a fixing frame, and then the fixing frame is mounted on the chassis. Because the fixing frame is used when the fan is installed, the cost of installing the fan is increased.

Contents of the invention

In view of the above, it is necessary to provide a low-cost fan fixing device.

A fan fixing device is used for fixing a fan. The fan is provided with two opposite end walls. The fan fixing device includes a bottom plate and two fixing pieces. The bottom plate is provided with four clamping posts. Each fixing piece includes a storage lock and a latch, the storage lock includes a first column that can pass through an end wall of the fan and a first fixing portion that can stop on the outside of the end wall, the latch includes the other end that can pass through the fan wall and is snapped into a second cylinder of the first cylinder of the storage lock and a second fixing part that is blocked on the outside of the other end wall, and the first and second fixing parts are respectively provided with corresponding clamping columns to pass through. through the fixing hole.

Compared with the prior art, the fan fixing device can fix the fan through the clamping column of the bottom plate and the two fixing parts, without the need of a fixing frame, and the cost is low.

The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings.

detailed description

Referring to FIG. 1 , a preferred embodiment of the fan fixing device of the present invention is used to fix several fans 10 . The fan fixing device includes a bottom plate 20 and a plurality of fixing parts 30 .

Each fan 10 includes two opposite end walls 12 . Each end wall 12 defines a through hole 120 at four corners.

The bottom plate 20 protrudes from a plurality of pairs of clamping posts 22 with tapered tops.

Each fixing member 30 includes a receiving lock 32 and a locking lock 34 .

The receiving lock 32 includes a fixing portion 320 and a column 322 extending outward from one side of the fixing portion 320 . The fixing portion 320 defines a fixing hole 324 extending through the top surface and the bottom surface thereof. A receiving hole 326 is defined on an end surface of the cylinder 322 away from the fixing portion 320 . A through hole 328 extending through two opposite sides of the cylindrical body 322 and communicating with the receiving hole 326 is defined along the radial direction of the cylindrical body 322 away from the fixing portion 320 .

The latch 34 includes a fixing portion 340 and a column 342 extending outward from a side of the fixing portion 340 . The fixing portion 340 defines a fixing hole 344 extending through the top surface and the bottom surface thereof. A pair of spaced apart hooks 346 facing away from the end surface of the cylinder 342 protrude from the end surface of the fixing portion 320 .

Please refer to FIG. 2 and FIG. 3 , when assembling each fan 10 , a cylinder 322 of a storage lock 32 passes through a perforation 120 at the bottom of an end wall 12 of the fan 10 , and a cylinder 322 of another storage lock 32 passes through the fan 10 A through hole 120 at the bottom of the other end wall 12 is away from the aforementioned through hole 120 , until the fixing portions 320 respectively block the outside of the corresponding end wall 12 . The cylinders 342 of the two latches 34 pass through the other two through holes 120 at the bottom of the fan 10 until the hook 346 of each cylinder 342 elastically deforms and locks into the corresponding receiving hole 326 of the receiving lock 32 . When each pair of hooks 346 faces the corresponding through hole 328 of the storage lock 32, the pair of hooks 346 elastically returns to pass through the through hole 328 and is locked on the opposite side of the circumferential surface of the cylinder 322 of the storage lock 32. side. At this time, the fixing portions 340 respectively block the outer sides of the corresponding end walls 12 of the fan 10 .

Then make the four posts 22 of the bottom plate 20 face to each other and pass through the fixing holes 324 and 344 to fix the fan 10 to the bottom plate 20 .

In other embodiments, the positions of each pair of storage locks 32 and locking locks 34 can be interchanged.

The fan fixing device can fix the fan through the clamping post 22 of the bottom plate and the two fixing pieces, without the need of a fixing frame, and the cost is low and the installation is convenient.
