Abstract:
An electronic device enclosure including a housing and a cover conveniently assembled with the housing is disclosed. The cover includes an installation member engaged in an installation hole defined in the housing. The blocking member is secured to the cover and comprises a blocking piece. The operation member is slidable relative to the blocking member between a locked position, where the blocking piece extends into the positioning hole and resists an edge of a positioning hole defined in the housing, preventing the installation member from disengaging from the installation hole; and an unlocked position, where the blocking piece is disengaged from the positioning hole, allowing the installation member to be disengaged from the installation hole.

     DETAILED DESCRIPTION 
       [0012]    The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. 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.” 
         [0013]      FIGS. 1-3  show one embodiment of an electronic device enclosure. The electronic device enclosure includes a housing  20 , a cover  10  secured to the housing  20 , a plurality of installation members  12 , a blocking member  30 , and an operation member  40 . The housing  20  defines a plurality of installation holes  22  corresponding to the installation members  12 . 
         [0014]    The blocking member  30  is configured for preventing the installation members  12  from disengaging from the installation holes  22 . The blocking member  30  includes a mounting plate  301 , a blocking piece  31 , two first blocking portions  361 , and two second blocking portions  363 . The mounting plate  301  defines a through hole  33 . In one embodiment, the through hole  33  is rectangular. The blocking piece  31  includes a connecting end  311  and a movable end  312 . The connecting end  311  extends from a first side edge of the through hole  33 . The movable end  312  extends slantingly from the connecting end  311  relative to the mounting plate  301 . The movable end  312  is elastically deformable relative to the mounting plate  301  to be received in the through hole  33  around the connecting end  311 . A sliding slot  32  extends from each of a top edge and a bottom edge of the through hole  33 . A length of the sliding slot  32  is less than a length of the through hole  33 . The first blocking portions  361  extend from opposite side edges of the mounting plate  301 . The second blocking portions  363  extend from a bottom edge of the mounting plate  301  and are elastically deformable relative to the mounting plate  301 . 
         [0015]    The operation member  40  can include two hooks  42 , two pairs of limiting portions  43 , and an operation portion  41 . The hooks  42  and the operation portion  41  extend from opposite directions. The hooks  42  engage with a top edge and a bottom edge of the blocking piece  31 . The limiting portions  43  slidably engage in the sliding slots  32 . 
         [0016]    The housing  20  can include a bottom plate  202  and two side plates  201  perpendicularly extending from the bottom plate  202 . The installation holes  22  can be defined in one of the side plates  201  in a line substantially parallel to the side plate  201 . Each of installation hole  22  includes a guiding portion  221  and a locking portion  222  communicating with the guiding portion  221 . The side plate  201  further defines two positioning holes  21  corresponding to the blocking piece  31 . 
         [0017]    The cover  10  can include a top wall  101  and two sidewalls  102  perpendicularly extending from the top wall  101 . Each installation member  12  includes a securing portion  121  and an installation portion  122  connected to the securing portion  121 . Each sidewall  102  defines two first securing holes  131  corresponding to the first blocking portions  361  and a sliding hole  134  corresponding to the operation portion  41 . A width of the sliding hole  134  is substantially the same as a width of the operation portion  41 . The top wall  101  defines a plurality of second securing holes  133  corresponding to the second blocking portions  363 . 
         [0018]    In one embodiment, each of the blocking member  30  and the operation member  40  is made of plastic. 
         [0019]      FIGS. 4-7  show that when an e-device enclosure is in an assembled configuration, the hooks  42  of the operation member  40  extend through the through hole  33  to engage the top edge of the bottom edge of the blocking piece  31  therebetween. The limiting portions  43  are slidably received in the sliding slots  32 . Thus, the operation member  40  is rotatably mounted to the mounting plate  301 . A sliding direction of the operation member  40  is substantially perpendicular to the side edge of the through hole  33 , from which the connecting end  311  of the blocking piece  31  extends. The first blocking portions  361  are engaged in the first securing holes  131 . The second blocking portions  363  are aligned with the second securing holes  133 . The mounting plate  301  is pressed to elastically deform the second blocking portions  363 . The second blocking portions  363  rebound to be engaged in the second securing holes  133  after extending out of the second securing holes  133 , to secure the blocking member  30  to the sidewall  12 . The operation member  40  and the blocking member  30  are located between the sidewall  102  and the side plate  201 . The operation portion  41  extends out of the sliding hole  134 . The operation member  40  is slidable relative to the blocking member  30  by sliding the operation portion  41  in the sliding hole  134 . 
         [0020]    When the cover  10  is in an assembled configuration, the operation portion  41  is pushed to slide the operation member  40  relative to the blocking member  30  to a locked position, where the limiting portion  43  abuts a first end of the sliding slot  32  adjacent to the connecting end  311 , the hooks  42  are adjacent to the connecting end  311 , and the movable end  312  slants relative to the mounting plate  301 . The cover  10  is placed above the housing  20  to align the installation members  12  with the guiding portions  221 . The cover  10  is pushed along a first direction, substantially perpendicular to the bottom plate  202 , to move the installation portions  122  in the guiding portions  221 . The sidewall  102  abuts the side plate  201 . The blocking piece  31  is pressed to be received in the through hole  33 . The cover  10  is pushed along a second direction, substantially parallel to the bottom plate  202 , to move the installation portions  122  to the locking portions  222  from the guiding portions  221 . The blocking member  30  is moved together with the cover  10  until the blocking piece  31  is aligned with the positioning hole  21 . The blocking piece  31  is released, and the movable end  312  rebounds to resist an edge of the positioning hole  21  from the through hole  33 , preventing the installation members  12  from moving along a third direction, which is opposite to the second direction, to disengage from the installation holes  22 . Thus, the cover  10  is secured to the housing  20 . 
         [0021]    When the cover  10  is in a disassembled configuration, the operation portion  41  is pushed to slide the operation member  40  relative to the blocking member  30  to an unlocked position, where the limiting portion  43  abuts a second end of the sliding slot  32  adjacent to the movable end  312 , the hooks  42  are adjacent to the movable end  312 , the movable end  312  is received in the through hole  33 , and the blocking piece  31  is coplanar with the mounting plate  301 . When the operation portion  41  is slid from the locked position to the unlocked position, the limiting portion  43  is slid from the first end of the sliding slot  32  to the second end of the sliding slot  32 , and the hooks  42  move from the connecting end  311  to the movable end  312 , causing the movable end  312  to be elastically deformed towards the sidewall  102  to be received in the through hole  33 . The cover  10  can be moved along the third direction to disengage the installation members  12  from the locking portions  222 , and then the cover  10  can be moved upward to be removed from the housing  20 .
