Abstract
An air duct includes a board defining an opening and a number of spaced plates pivotably mounted to the board along a lengthwise direction of the opening. Each plate defines a cutout in a first side. The plates are pivoted to be parallel to the board to cover the opening. The plates are pivoted away from the board to expose the opening, and the cutouts are operable to receive an end of an expansion card when the plates are pivoted to be perpendicular to the board.
Description
- 1. Technical Field
- The present disclosure relates to an air duct.
- 2. Description of Related Art
- Air ducts are often used to fix distal ends of expansion cards to prevent the distal ends of the expansion cards from falling down. A plurality of through holes is defined in the air duct to allow airflow flows through to dissipate heat generated by the expansion card. As a result, although there is no expansion card fixed to the air duct, airflow still flows through the through holes, which is undesirable for regulating airflows.
- Many aspects of the present embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments. Moreover, in the drawings, all the views are schematic, and like reference numerals designate corresponding parts throughout the several views.
-
FIG. 1 is an assembled, isometric view of an exemplary embodiment of an air duct including a plurality of latches and a plurality of plates, together with an expansion card. -
FIG. 2 is similar toFIG. 1 , but showing another using state. -
FIG. 3 shows another embodiment of the latch ofFIG. 1 . -
FIG. 4 shows another embodiment of the plate ofFIG. 1 . - The disclosure, including the accompanying drawings, is illustrated by way of example 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.
- Referring to
FIG. 1 , an exemplary embodiment of an air duct is provided for fixing an end of anexpansion card 40. The air duct includes aboard 10 and a plurality ofplates 32. - The
board 10 defines arectangular opening 12. Atop piece 120 and abottom piece 122 perpendicularly extending forward from theboard 10, respectively at a top side and a bottom side of the opening 12. Thetop piece 120 and thebottom piece 122 each define a plurality offixing holes 126. Arib 20 coplanar with theboard 10 is connected between the middles ofopposite ends 124 of the opening 12. A plurality of spacedlatches 26 is mounted on a front surface of therib 20 and is longitudinally arranged along a lengthwise direction of therib 20. Eachlatch 26 includes anextension portion 261 connected to therib 20, acantilever 263 perpendicularly extending out from an end of theextension portion 261, and aprojection 264 extending from a left side of thecantilever 263. Theprojection 264 includes aslanted surface 268 slantingly extending rearward from a distal end of thecantilever 263 and ablocking surface 270 parallel to theextension piece 261 and connected between theslanted surface 268 and thecantilever 263. - Each
plate 32 is rectangular, and defines acutout 320 in a first side. Twopins 34 respectively extend out from opposite ends of a second side of theplate 32 opposite to the first side. Thepins 34 are pivotably inserted into twoopposite fixing holes 126 of the top andbottom pieces plate 32 to theboard 10 between the top andbottom pieces plate 32 is positioned at a left side of one of thelatches 26. - Referring to
FIG. 2 , in covering theopening 12, each of theplates 32 is pivoted rightward to allow a corresponding one of thelatches 26 to extend through thecutout 320. An inner surface bounding thecutout 320 slides along theslanted surface 260 to deform thecorresponding cantilever 263, until theplate 32 contacts therib 20 and theblocking surface 270 abuts a surface of theplate 32 opposite to therib 20. - Referring again to
FIG. 1 , in holding the end of theexpansion card 40, thelatches 26 are pivoted away from thecorresponding plates 32, to allow theblocking surfaces 270 to disengage from thecorresponding plates 32. Theplates 32 are then pivoted forward to be perpendicular to theboard 10 and to expose theopening 12. The end of theexpansion card 40 can be engaged in thecutouts 320. Airflow may flow toward theexpansion card 40 through theopening 12. - Referring to
FIG. 3 , in another embodiment, a plurality of spacedlatches 27 replaces the above-mentionedlatches 26. Eachlatch 27 includes anextension portion 261, afixing portion 260 perpendicularly extending rearward from a left end of theextension portion 261 to be connected to therib 20, acantilever 263 perpendicularly extending forward from a right end of theextension portion 261 opposite to the left end, aprojection 264 extending from a left side of thecantilever 263, and aspring 262 mounted between a rear side of theextension portion 261 and therib 20. - Referring to
FIG. 4 , in another embodiment, therib 20 and the latches can be omitted. Eachplate 50 is rectangular. Atab 51 extends out from a first side of theplate 50. Aprotrusion 52 protrudes from one of opposite sides of thetab 51. Twopins 54 extend out from opposite ends of the first side of theplate 50. Acutout 56 aligning with thetab 51 is defined in a second side of theplate 50 opposite to the first side. In covering the opening 12, theplates 50 are pivoted rearward, the second side of one of the twooutmost plates 50 are tightly abutted against one of theends 124 of the opening 12, theother plates 50 each are abutted against thetab 51 of anadjacent plate 50, and theprotrusion 52 of each of theother plates 50 is engaged in thecutout 56 of theadjacent plate 50. - It is believed that the present embodiments and their advantages will be understood from the foregoing description, and various changes may be made thereto without departing from the spirit and scope of the description or sacrificing all of their material advantages, the examples hereinbefore described merely being exemplary embodiments.
