  • a top portion of the frame 41 extends upward to form a lock 43 .
  • the lock 43 includes a connection piece 431 , a bent piece 432 , and a handle 433 .
  • the connection piece 431 is connected to the frame 41 .
  • the bent piece 432 is perpendicularly connected to a top portion of the connection piece 431 .
  • the handle 433 is perpendicularly connected to the bent piece 432 .
  • a tab 435 is formed on a connection portion of the bent piece 432 and the connection piece 431 .
  • a center portion of the frame 41 is hollow to define a frame opening 418 .
  • a plurality of parallel pivot shafts 413 are pivotally mounted in the frame opening 418 .
  • the plurality of parallel pivot shafts 413 are aligned in a vertical direction.
  • Each of the plurality of pivot shafts 413 secures a shielding piece 46 .
  • the shielding piece 46 includes a securing portion 467 and a free portion 468 .
  • the securing portion 467 is secured on corresponding one of the plurality of pivot shafts 413 .

  • the shielding piece 46 includes a first side face 461 and a second side face 462 . Between adjacent two of the shielding pieces 46 , the second side face 462 of the free portion 468 of one of the shielding piece 46 is located on the first side face 461 of the securing portion 467 of another one of the shielding piece 46 . All of the shielding pieces 46 mounted on the plurality of pivot shafts 413 can shield the entire frame opening 418 . An edge of the frame opening 418 forms a plurality of blocking bars 417 corresponding to each of the shielding
  • FIGS. 1 to 5 show in assembly, the fan 30 is placed into the fan receiving room of each of the plurality of receiving rooms 27 .
  • the elastic piece 35 is elastically bent by each of the plurality of partitions 25 .
  • the fan 30 is moved until the protrusion 351 is aligned to the mounting hole 253 .
  • the elastic piece 35 rebounds to insert the protrusion 351 in the mounting hole 253 mounting the fan 30 in each of the plurality of receiving rooms 27 . In this position, the fan 30 is aligned to the second vent opening 231 .
  • the shield 40 is placed into the shield receiving room of each of the plurality of receiving rooms 27 .
  • the second side plate 462 of each of the plurality of shielding piece 46 faces the fan 30 .
  • the tab 435 of the shield 40 is locked in the notch 213 of the rack 20 mounting the shield 40 in each of the plurality of receiving rooms 27 .
