Description

Fan fixture

The present invention relates to a fixing device, and more particularly to a fan fixing device.

In the conventional storage server, the fan module is usually fixed on the housing substrate of the storage server by using screws such as screws and bolts. This method can achieve stable fixing effect; however, when the fan module is disassembled and assembled, Tools are needed and the operation is complicated. In addition, there are many fan modules that are fixed by hot plugging. These fan modules do not need to use tools for disassembly and assembly, but they need to overcome the large insertion force and are difficult to pull out, so that they can be repaired or replaced. Brought a lot of inconvenience.

In view of this, it is necessary to provide a fan fixing device that is easy to assemble and disassemble.

A fan fixing device for fixing a group of fans to a casing of an electronic device, the fan fixing device comprising a fan holder accommodating a plurality of fans, a second locking mechanism and two levers, each of the The lever includes a first end and a second end that are oppositely disposed, each of the first ends being slidably fixed to the locking mechanism, and each of the second ends is rotatably fixed to the fan holder And abutting against the housing; when the locking mechanism is pulled, the lever is detached from the housing by the locking mechanism.

The fan fixing device of the present invention rotates the lever around the rotating shaft by the locking mechanism by using the locking mechanism, thereby driving the fan fixing frame to move upward or downward, without disassembling the tool, The fan fixing frame with the fan fixed is quickly disassembled and assembled, and the operation is labor-saving and the device structure is simple.

Referring to FIG. 1 , a preferred embodiment of the fan fixture 100 of the present invention is used to secure the plurality of fans 200 in a housing 300 of an electronic device.

The housing 300 includes a bottom plate 301 and two side plates 303 extending from opposite sides of the bottom plate 301.

As shown in FIG. 2 , the fan fixing device 100 includes a fan holder 10 , a locking mechanism 20 slidably fixed to the two ends of the fan holder 10 , and two levers 30 . Each of the levers 30 includes a first end 32 and a second end 34 that are oppositely disposed. The first end 32 is slidably fixed to the locking mechanism 20, and the second end 34 and the side plate 303 It is rotatably and rotatably fixed to the fan holder 10. Pulling the locking mechanism 20 detaches the fan holder 10 from the housing 300.

The fan holder 10 includes two end walls 11 and two partition walls 13 , and the end walls 11 are respectively disposed adjacent to the two side plates 303 of the housing 300 .

As shown in FIG. 3, each of the locking mechanisms 20 includes a locking member 21 and a slot 23 and a lower slot 25 on one of the spacers. The partition wall 13 is disposed between each of the lock members 21 and the fan 200.

Each of the locking members 21 includes a pressing arm 211, a buckle 213, a connecting shaft 215 and two opposite sidewalls 217. Both ends of the connecting shaft 215 are rotatably fixed to the inner surfaces of the two side walls 217, respectively. The pressing arm 211 and the buckle 213 are rotatably coupled together by the connecting shaft 215. When the buckle 213 is engageable in the upper card slot 23 or the lower card slot 25, when the pressing arm 211 is pressed to rotate in the direction of the partition wall 13, the connecting shaft 215 rotates and drives The buckle 213 is rotated away from the partition wall 13 to disengage the buckle 213 from the upper card slot 23 or the lower card slot 25.

The buckle 213 includes a wedge surface 2131. When the buckle 213 is engaged in the upper card slot 23 or the lower card slot 25, the wedge surface 2131 abuts against the slot wall of the upper card slot 23 or the lower card slot 25. When the user forgets to engage the buckle 213 in the upper card slot 23 or the lower card slot 25, the wedge surface 2131 can force the buckle 213 into the lower card slot 25 for preventing The lock member 21 is free to fall, so that the lock member 21 is stably stopped in the state shown in FIG.

The locking member 21 can be made of an elastic material such as PVC or PU.

3-5, the lever 30 is slidably fixed to the locking member 21 in such a manner that the lever 30 includes two protrusions 31 disposed at the first end 32. The fan fixture 100 further includes two sliding slots 40 respectively disposed on the side walls 217. Each of the protrusions 31 is slidably received in one of the sliding grooves 40 to slidably fix one end of the lever 30 to the locking member 21. In this embodiment, each of the protrusions 31 is respectively protruded on two opposite outer surfaces of the lever 30. Each of the sliding slots 40 includes a first slot wall 41 and a second slot wall 43 opposite the first slot wall 41.

As shown in FIG. 4 , the lever 30 is rotatably fixed to the fan holder 10 in such a manner that the lever 30 further includes two rotating shafts 33 disposed on the second end 34 . The fan holder 10 further includes a shaft hole 15 disposed opposite to the rotating shaft 33. The rotating shafts 33 are respectively mounted in the shaft holes 15. In this embodiment, each of the rotating shafts 33 protrudes from one end of the lever 30 away from the protruding post 31.

The end of the second end 34 of the lever 30 is abutted against the side plate 303. The fan fixing device 100 further includes two limiting mechanisms 50. The limiting mechanism 50 includes two limiting slots 51 disposed on the end wall 11 and two limiting protrusions 53 disposed on the side plate 303 . The limiting slot 51 and the limiting protrusion 53 are used to limit the distance that the lever 30 moves up and down. In this embodiment, each of the limiting bumps 53 includes an upper surface 531 and a lower surface 533 opposite to the upper surface 531. The lever 30 further includes a limiting arm 35 disposed on the second end 34. The limiting arm 35 is disposed adjacent to the two rotating shafts 33. The limiting arm 35 includes a first limiting portion 351. The second limiting portion 353 and a groove 355 are formed between the first limiting portion 351 and the second limiting portion 353. The groove 355 is disposed opposite to the limiting protrusion 53. When the fan 200 is installed in the housing 300, the protrusion 31 abuts against the first slot wall 41, and the first limiting portion 351 of the limiting arm 35 passes through the limit. The slot 51 abuts against the lower surface 533 of the limiting protrusion 53 for fixing the fan holder 10 in the housing 300.

When the fan 200 is disassembled, the pressing arm 211 is first pressed to rotate in the direction of the fan 200, and the buckle 213 is driven by the pressing arm 211 to rotate away from the fan 200. The lower slot 25 is disengaged; then, the latching member 21 is pulled up, and the latch 31 of the lever 30 is guided by the first slot wall 41 of the slot 40 by the latching member 21 The two-slot wall 43 slides while the lever 30 rotates around the rotating shaft 33, and the limiting arm 35 rotates around the limiting protrusion 53; when the protruding post 31 is returned by the second groove wall 43 again When the first groove wall 41 abuts, the lever 30 stops rotating and the buckle 213 is engaged in the upper card slot 23; thus, the fan 200 is detached from the housing 300.

Referring to FIG. 5 and FIG. 6 together, when the fan 200 is installed, the pressing arm 211 is first pressed to rotate in the direction of the fan 200, and the buckle 213 is driven by the pressing arm 211. Rotating away from the fan 200 to be detached from the upper card slot 23; then, pressing the locking member 21 downward, and under the driving of the locking member 21, the protrusion 31 of the lever 30 is The first groove wall 41 of the chute 40 slides toward the second groove wall 43 while the lever 30 rotates around the rotating shaft 33; when the stud 31 is returned to the first groove wall by the second groove wall 43 When the position of the 41 is resisted, the lever 30 stops rotating and the buckle 213 is engaged in the lower card slot 25, so that the fan 200 is mounted on the housing 300.

The fan fixing device 100 of the present invention rotates the lever 30 about its rotating shaft 33 by the locking mechanism 20, thereby driving the fan 200 to move upward or downward without disassembling the tool. Under the condition, the fan module is quickly disassembled and assembled, and the operation is labor-saving and the device structure is simple.
