AIR DUCT
Abstract
An air duct includes a frame and a number of guiding members
detachably mounted to the frame. The frame includes two opposite
sidewalls each defining a number of through holes. Each guiding

Claims
1. An air duct, comprising: a frame comprising two opposite
sidewalls each longitudinally defining a plurality of through
holes; and a plurality of guiding members detachably mounted
between the sidewalls, each guiding member comprising a plate and a
pole connected to a side of the plate, opposite ends of the pole
and rotatably extending through two corresponding ones,
respectively defined in the two sidewalls, of the through holes,
two protrusions formed at opposite ends of the pole, each
protrusion extending through one of the through holes and blocked
by an outer surface of the corresponding sidewall.
2. The air duct of claim 1, wherein a protecting portion extends
from the circumference of the pole, adjacent to each of opposite
ends of the plate and blocked by an inner surface of the
corresponding sidewall opposite to the corresponding
protrusion.
3. The air duct of claim 1, wherein each through hole comprises two
fan-shaped holes communicating with each other, each protrusion
comprises two fan-shaped blocks connected to each other and
respectively extending through the corresponding fan-shaped holes
of the corresponding through hole and blocked by the outer surface
of the corresponding sidewall.
4. The air duct of claim 3, wherein two engaging protrusions extend
from the circumference of the pole between each protrusion and the
corresponding protecting portion and respectively spaced from the
two protrusions; said two fan-shaped blocks of each protrusion
forms two concave portions at a joint of the two fan-shaped blocks
and each of the two engaging protrusions aligns with one of the two
concave portions and is movably received in one of the
corresponding fan-shaped holes.
Description
BACKGROUND
[0001] 1. Technical Field
[0002] The present disclosure relates to an air duct.
[0003] 2. Description of Related Art
[0004] An air duct for guiding airflow generated by a fan generally
includes a frame including two opposite sidewalls, and a plurality
of guiding pieces detachably mounted between the sidewalls. Each
sidewall defines a plurality of fixing holes, opposite ends of each
guiding piece are inserted into two corresponding fixing holes of
the sidewalls, to fix the guiding piece to the sidewalls. However,
these guiding pieces may be disengaged from the corresponding
fixing holes easily. As a result, the guiding pieces may drop into
the frame and cause damage to the fan.
BRIEF DESCRIPTION OF THE DRAWINGS
[0005] 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.
[0006] FIG. 1 is an assembled, isometric view of an exemplary
embodiment of an air duct and a fan.
[0007] FIG. 2 is an exploded, isometric view of the air duct of
FIG. 1.
[0008] FIG. 3 is an enlarged view of the circled portion III of
FIG. 1.
DETAILED DESCRIPTION
[0009] 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.
[0010] Referring to FIG. 1 to FIG. 3, an exemplary embodiment of an
air duct includes a frame 10 and a plurality of guiding members 20
for guiding airflow generated by a fan 40.
[0011] The frame 10 includes two opposite sidewalls 12, a top wall
14 perpendicularly connected between top ends of the sidewalls 12,
a bottom wall 16 perpendicularly connected between bottom ends of
the sidewalls 12, and a cover 18 perpendicularly connected to front
sides of the sidewalls 12, the top wall 14, and the bottom wall 16.
Each sidewall 12 longitudinally defines a plurality of through
holes 120 adjacent to a rear side of the sidewall 12. Each through
hole 120 includes two fan-shaped holes 122 communicating with each
other.
[0012] Each guiding member 20 includes a plate 24, and a pole 22
connected to a side of the plate 24. An annular protecting portion
26 extends from the circumference of the pole 22, at each end of
the plate 24. A protrusion 28 is formed on each of opposite ends of
the pole 22. Each protrusion 28 comprises two fan-shaped block 280
connected to each other. Two engaging protrusions 30 protrude from
the circumference of the pole 22 between each protrusion 28 and the
corresponding protecting portion 26. Each engaging portion 30 is
perpendicularly connected to an outer surface of the corresponding
protecting portion 26 away from the other protecting portion 26,
spaced from the corresponding protrusion 28, and perpendicular to
the fan-shaped block 280. Each engaging portion 30 also aligns with
one of the two concave portions 282 formed at the joint of the
fan-shaped block 280.
[0013] In assembly of each guiding member 20 to the frame 10, the
guiding member 20 is deformed to curve. The protrusions 28 aligning
with the corresponding through holes 120 of the sidewalls 12 from a
space between the sidewalls 12, and the fan-shaped blocks 280 are
aligned with the corresponding fan-shaped holes 122. The guiding
member 20 is then allowed to restore, thereby the fan-shaped blocks
280 are extend through the corresponding fan-shaped holes 122. The
blocks 280 are then rotated about 90 degrees and blocked by outer
surfaces of the corresponding sidewalls 12, to prevent the guiding
member 20 from disengaging from the sidewalls 12. At this time, the
engaging protrusions 30 are aligned with and movably received in
the corresponding fan-shaped holes 122. The protecting portions 26
are respectively blocked by inner surfaces of the sidewalls 12
opposite to the blocks 280. The fan 40 is accommodated among the
cover 18, the guiding members 20, the sidewalls 12, the top wall
14, and the bottom wall 16.
[0014] In use, if the direction of the airflow from the fan 40
needs to be adjusted, each of the guiding members 20 can be rotated
about the pole 22. The rotation angle of the guiding member 20 can
be limited by the engaging portions 30 contacting the sidewalls 12
at the joints of the fan-shaped holes 122.
[0015] 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.
