Description

Fan holder

The present invention relates to a fan holder.

In the prior art, the fan is usually mounted in a computer system through a fan holder. Each fan has two opposite end plates, and the thickness between the end plates is often different for different types of fans. When a fan of different thickness is installed in the computer system as needed, the fan holder in the computer system also needs to be replaced together.

In view of the above, it is necessary to provide a fan holder that can accommodate fans of different thicknesses.

A fan fixing frame includes a bottom plate, a fixing wall extending vertically upward from one end of the bottom plate, and a fixing member mounted on the bottom plate and slidable in a direction perpendicular to the fixing wall, the fixing wall and the fixing member A plurality of locking posts are respectively disposed opposite to each other for locking into corresponding fixing holes on opposite end walls of a fan, and the bottom plate is provided with a plurality of locking holes spaced apart in a direction perpendicular to the fixing wall, and the fixing member is provided with a The fixing portion has a perforation, and a screw can pass through the through hole of the fixing portion to lock into a corresponding locking hole of the bottom plate.

The fixing member of the fan holder can slide in a direction perpendicular to the fixing wall and be locked to different locking holes, thereby being adapted to install fans of different thicknesses.

Referring to FIG. 1, a preferred embodiment of the fan holder of the present invention is used to fix fans 50 of different thicknesses. The fan holder includes a fixing base 10 and a fixing member 20.

The fixing base 10 includes a bottom plate 12, a fixing wall 14 extending vertically upward from one end of the bottom plate 12, and two side walls 16 extending vertically upward from opposite sides of the bottom plate 12. The central portion of the bottom plate 12 is provided with a plurality of locking holes 121 spaced apart in a direction parallel to the two side walls 16. A vent 141 is provided in the middle of the fixed wall 14. A locking post 143 is respectively disposed at a side of the fixing wall 14 facing the bottom plate 12 at a position adjacent to the four corners. Each of the locking posts 143 is adjacent to the fixing wall 14 and is provided with a plastic spacer 145 for preventing vibration. An inner side of each side wall 16 is convexly disposed adjacent to the bottom plate 12 with an elongated flange 163 extending in a direction perpendicular to the fixed wall 14. A sliding groove 165 is formed between each flange 163 and the bottom plate 12.

The fixing member 20 includes a laterally elongated baffle 21, a fixing portion 23 protruding from the middle of the bottom of one side of the baffle 21, and two adjacent protrusions on the other side of the baffle 21 Two locking posts 25 at the ends. A bump 212 is protruded outwardly from the bottom of each end of the baffle 21 . An opening 214 is defined downward in the middle of the top of the baffle 21. The fixing portion 23 is provided with a through hole 231 downward. Two shock-proof plastic spacers 27 are respectively sleeved on the two locking posts 25 adjacent to the baffle 21.

Fan 50 includes two opposing end plates 51. Each end plate 51 is provided with a vent 515. A fixing hole 513 is respectively disposed at each of the end plates 51 adjacent to the four corners.

Referring to FIG. 2 , when the fan 50 is to be fixed to the fan holder, the fan 50 is first placed on the bottom plate 12 of the fixing base 10 and slidably sandwiched between the side walls 16 . The one end plate 51 of the fan 50 faces the fixed wall 14. The fan 50 is slid to the fixed wall 14 so that the four locking posts 143 on the fixed wall 14 are respectively locked into the four corresponding fixing holes 513 of the fan 50. The plastic spacer 145 on the four locking posts 143 abuts the fan 50. The vent 141 of the fixed wall 14 is facing the vent 515 of the fan 50. The two protrusions 212 of the fixing member 20 are inserted into the two sliding slots 165 from the end of the fixing base 10 away from the fixing wall 14, so that the fixing member 20 is supported on the bottom plate 12, and the two locking posts of the fixing member 20 are 25 faces the fixed wall 14. The fixing member 20 is slid along the two sliding grooves 165 to the fixing wall 14 until the two locking posts 25 of the fixing member 20 are respectively inserted into the two fixing holes 513 of the fan 50 facing the bottom of the end plate 51 of the fixing wall 14 . The plastic spacer 27 on the two locking posts 25 abuts the fan 50. At this time, the opening 214 of the baffle 21 is opposite to the lower portion of the vent 515 of the fan 50, and does not block the inflow and out of the wind flow. The through hole 231 of the fixing portion 23 is facing a locking hole 121 on the bottom plate 12, so that A screw 60 passes through the through hole 231 and is locked into the locking hole 121, that is, the fixing member 20 is fixed to the bottom plate 12. At this time, the fan 50 is sandwiched between the two side walls 16, the fixed wall 14 and the fixing member 20, and the fan 50 is fixed to the fan holder.

Since the fixing member 20 of the fan holder of the present invention can slide along the two sliding grooves 165 after the screw 60 is removed, when the fan of different thickness is to be fixed, the fixing member 20 only needs to be slid, and the fan is placed Between the two side walls 16, the fixing wall 14 and the fixing member 20, the screw 60 is finally passed through the through hole 231 of the fixing portion 23 and locked into a corresponding locking hole 121 of the bottom plate 12, so that the fan can be fixed.

In other embodiments, the fixing member 20 can be slidably mounted on the bottom plate 12 by other means. For example, two sliding slots or sliding rails are directly disposed on the bottom plate 12, and two sliding rails are correspondingly disposed at the bottom of the fixing member 20. Or chute.

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.
