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

Detailed ways

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

The fixing base 10 includes a bottom plate 12 , a fixing wall 14 vertically upwardly extending from one end of the bottom plate 12 , and two side walls 16 perpendicularly extending upwardly from two opposite sides of the bottom plate 12 . A central portion of the bottom plate 12 defines a plurality of locking holes 121 at intervals along a direction parallel to the two sidewalls 16 . A vent 141 is defined in the middle of the fixed wall 14 . A side of the fixed wall 14 facing the bottom plate 12 is respectively provided with a locking column 143 adjacent to four corners, and each locking column 143 is adjacent to the fixed wall 14 and is sleeved with a plastic spacer 145 for anti-shock function. An elongated flange 163 protrudes from an inner side of each side wall 16 adjacent to the bottom plate 12 and extends along a direction perpendicular to the fixing wall 14 . A slide slot 165 is formed between each flange 163 and the bottom plate 12 .

The fixing part 20 includes a horizontal strip-shaped baffle 21, a fixing part 23 protruding from the middle of the bottom of one side of the baffle 21, and two adjacent two sides protruding from the other side of the baffle 21. Two locking posts 25 at the end. Two protrusions 212 protrude outward from bottoms of two ends of the baffle plate 21 . An opening 214 is downwardly defined in the middle of the top of the baffle 21 . The fixing portion 23 defines a through hole 231 downward. Two anti-vibration plastic gaskets 27 are sleeved on the two locking cylinders 25 adjacent to the baffle plate 21 respectively.

The fan 50 includes two opposite end plates 51 . Each end plate 51 defines a vent 515 . Each end plate 51 defines a fixing hole 513 adjacent to four corners thereof.

Referring to FIG. 2 , to fix the fan 50 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 two side walls 16 . An end plate 51 of the fan 50 faces the fixed wall 14 . Slide the fan 50 toward the fixing wall 14 so that the four locking posts 143 on the fixing wall 14 are respectively locked into the four corresponding fixing holes 513 of the fan 50 . The plastic spacers 145 on the four locking posts 143 abut against the fan 50 . The air vent 141 of the fixed wall 14 faces the air vent 515 of the fan 50 . The two projections 212 of the fixing member 20 are inserted into the two sliding grooves 165 from the end of the fixing seat 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 25 towards the fixed wall 14 . Slide the fixing member 20 toward the fixing wall 14 along the two slide grooves 165 until the two locking posts 25 of the fixing member 20 are respectively inserted into the two fixing holes 513 at the bottom of an end plate 51 of the fan 50 facing away from the fixing wall 14 , the plastic spacers 27 on the two lock posts 25 abut against the fan 50 . At this time, the opening 214 of the baffle plate 21 is right at the bottom of the air vent 515 of the fan 50, so as not to block the air flow in and out, and the perforation 231 of the fixing part 23 is right at a locking hole 121 on the bottom plate 12, so that A screw 60 passes through the through hole 231 and locks into the locking hole 121 , that is, fixes the fixing member 20 to the bottom plate 12 . At this time, the fan 50 is sandwiched between the two side walls 16 , the fixing wall 14 and the fixing member 20 , and the fan 50 is fixed on the fan fixing frame.

Since the fixing part 20 of the fan fixing frame of the present invention can slide along the two slide grooves 165 after the screw 60 is removed, when a fan with a different thickness is to be fixed, only the fixing part 20 needs to be slid, and the fan is clamped on the Between the two sidewalls 16, the fixing wall 14 and the fixing member 20, finally screw 60 through the perforation 231 of the fixing part 23 and lock into a corresponding locking hole 121 on the bottom plate 12, and then the The fan is fixed.

In other embodiments, the fixing member 20 can also be slidably installed on the bottom plate 12 in other ways, such as directly setting two sliding grooves or sliding rails on the bottom plate 12, and correspondingly setting two sliding rails at the bottom of the fixing member 20. or chute.
