Title: Server cabinet

Description:
BACKGROUND 
     1. Technical Field 
     The present disclosure relates to a server cabinet. 
     2. Description of Related Art 
     A server cabinet includes a receiving space for stacking a plurality of servers. When the server is removed from the server cabinet, an opening is left in the server cabinet and should be shielded, otherwise the air outside the server cabinet flows into the cabinet to interfere with the normal airflow in the server cabinet and possibly impair heat dissipation in the server cabinet.

     DETAILED DESCRIPTION 
     The present disclosure, including the accompanying drawings, is illustrated by way of examples and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one. 
       FIGS. 1-3 , is an exemplary embodiment of a server cabinet  100  including a rack  20 , a plurality of pairs of shielding members  40 , a plurality of elastic members  60 , and a plurality of servers  80 . 
     The rack  20  includes two opposite sidewalls  22  and a plurality of rails  24  respectively mounted to inner sides of the sidewalls  22 . A receiving space  26  is formed between each pair of rails  24  for receiving a server  80 . 
     Each rail  24  includes a rectangular connecting plate  242  fixed to the corresponding sidewall  22 , a supporting plate  243  perpendicularly extending in from a bottom side of the connecting plate  242 , and a positioning plate  244  perpendicularly extending in from a top side of the connecting plate  242  opposite to the supporting plate  243 . A width of the supporting plate  243  is larger than a width of the positioning plate  244 . A front end of the connecting plate  242  defines a latching hole  245 . Front ends of the supporting plate  243  and the positioning plate  244  each define a fixing hole  246 . A guiding slot  247  is defined in the supporting plate  243 . A front portion of the guiding slot  247  is quarter-circled, thus a quarter-circled guiding portion  243   a  is formed from the supporting plate  243  neighboring the guiding slot  247 . A circle center of the guiding portion  243   a  is located at the fixing hole  246 . A first stopping portion  248  protrudes in from the supporting plate  243 , at a front end of the guiding portion  243   a , along a direction perpendicular to the sidewall  22 . A second stopping portion  247   a  is formed on an end wall bounding the guiding slot  247 , at a rear end of the guiding portion  243   a  and adjacent to the connecting plate  242 . A tab  249  perpendicularly protrudes up from the front end of the positioning plate  244 , parallel to the connecting plate  242 . 
     Each shielding member  40  includes a substantially rectangular shielding panel  42 , and two spaced blocks  422  extending out from a first end of the shielding panel  42 . The blocks  422  and the shielding panel  42  cooperatively bound a cutout  424 . The blocks  422  define two through holes  425  communicating with the cutout  424 , and aligning with each other. A protrusion  46  extends down from the shielding panel  42 , adjacent to the through holes  425 . A distance between the protrusion  46  and the adjacent through hole  425  is substantially equal to a distance between the fixing hole and the guiding portion  243   a  of the supporting plate  243 . 
     In the embodiment, each elastic member  60  is a torsion spring. The elastic member  60  includes a helical main body  61 , a first pin  62  extending out from a first end of the main body  61 , and a second pin  64  extending out from a second end of the main body  61 . 
       FIG. 4  and  FIG. 5 , show in assembly, the elastic member  60  is received in the cutout  424 , the second pin  64  of the elastic member  60  abuts against the shielding panel  42 . The combination of the shielding member  40  and the elastic member  60  is received in the corresponding rail  24 , between the supporting plate  243  and the positioning plate  244 . The first pin  62  is inserted into the latching hole  245 , and the protrusion  46  is slidably received in the guiding slot  247 . A shaft  44  extends through the through holes  425  of the blocks  422  and the main body  61  of the elastic member  60 . Two opposite ends of the shaft  44  are fixed in the corresponding fixing holes  246 . The shielding member  40  rotates about the shaft  44 . The elastic member  60  is resiliently sandwiched between the shielding panel  42  and the corresponding rail  24 , to give resistance to the shielding member  40  to rotate substantially perpendicular to the sidewall  22 . Therefore, the protrusion  46  is slid in the guiding slot  247  blocked by the first stopping portion  248 . Second ends of each pair of shielding members  40  opposite to the corresponding blocks  422  are lapped with each other, to shield the receiving space  26 . 
     In assembly of the server  80  to the rack  20 , the server  80  is inserted into the corresponding receiving space  26  from the front end of the rack  20 . An end side of the server  80  slidably abuts against the shielding panels  42 , to give resistance to the shielding members  40  to rotate inward about the corresponding shafts  44 , deforming the elastic members  60 . The protrusions  46  are slid in the corresponding guiding slot  247  along the corresponding guiding portion  243   a  from the first stopping portion  248  to the second stopping portion  247   a . A bottom side of the server  80  is slidably supported on the supporting plates  243 , and two opposite sides of the server  80  are slidably engaged with the corresponding tabs  249 , until the shielding panels  42  rotate to be parallel to the connecting plates  242 . The protrusions  46  are blocked by the corresponding second stopping portions  247   a . Thus, the server  80  is mounted within the rack  20 . 
     When detaching each server  80  from the rack  20 , the server  80  is pulled out from the corresponding receiving space  26 . The elastic members  60  are restored to give resistance to the shielding members  40  to rotate outward. The protrusions  46  are slid in the corresponding guiding slot  247  along the corresponding guiding portion  243   a  from the second stopping portions  247   a  to the first stopping portions  248 , until the protrusions  46  are blocked by the corresponding first stopping portions  248 . Thus, the shielding members  40  shield the receiving space  26 . 
     In another embodiment, a shielding member  40  having a length equal to a width of the receiving space  26  replaces the pair of shielding members  40 . The shielding member is rotatably connected to an end of one of a corresponding pair of rails  24 , to shield the receiving space  26 . 
     While the disclosure describes examples and embodiments, it is to be understood that the disclosure is not limited thereto. On the contrary, the disclosure is intended to cover various modifications and similar arrangements as would be apparent to those skilled in the art. Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
