The erection part 41 of extension, it is illustrated that erection part is to bend out from 11 outer end of the first telescopic rod, 12 outer end of the second telescopic rod, uprightly
Portion is equipped with fastener hole 411, the fixed part for erection part to be fixed on to by fastener such as screw across the fastener hole furred ceiling
On position such as beam 06（Referring to Fig. 7）.Referring to Fig. 4-5, in order to reinforce the intensity of the erection part, erection part is equipped with structural strengthening portion
412, fastener hole 411 is set in structural strengthening portion 412, it is preferred that structural strengthening portion 412 is that bending deformation is formed from erection part
The structures such as this side, chimb.
Referring to Fig. 4-5, for the ease of being positioned when installation, erection part 411 be equipped with can outward bending locating plate 413,
When installation, locating plate outward bending is protruded into erection part, locating plate 413 is enabled to be resisted against the bottom surface of beam 06（Referring to Fig. 9）Realization pair
The positioning of first telescopic rod, the second telescopic rod.
Referring to Fig. 6 b, Fig. 9, in order to be positioned to ventilation fan in installation ventilation fan, the side of slide bar 13 towards mounting hole is equipped with
Flange 133 is positioned, is resisted against in the positioning flange in installation ventilation fan season ventilation fan and realizes positioning.
Referring to Fig. 1-3, it includes the first folding rod 21, the second folding rod 22, one end of the first folding rod to fold bar assembly 02
It is rotatablely connected with one end of the second folding rod, the other end of the first folding rod and the other end of the second folding rod are rotatablely connected respectively
On the slide bar 13 of two retractable rods.From there through the folding or expansion of the first folding rod, the second folding rod, two are stretched
Contracting bar assembly is strutted or is collapsed.First folding rod, the second folding rod are preferably bent by sheet metal forming.
Specifically, referring to Fig. 6 b, the both ends of slide bar 13 towards the side of mounting hole 03 are equipped with pivot block 134, the first folding
The other end of folded bar is rotatably connected in the pivot block on the slide bar of a retractable rod, the other end rotation of the second folding rod
It is connected in the pivot block on the slide bar of another retractable rod.
Preferably, referring to Fig. 6 b, pivot block 134 include a vertical flanging 135 and two from vertical flanging it is upper below
The lateral flap 136 for rotation connection that edge is symmetrically bent out to mounting hole.The end abutment lateral flap of vertical flanging 135
136 position respectively upwards, extend downwardly out positioning blocking portion 137, to stop the first folding rod, the second folding rod it is excessive to
It is unfolded outside mounting hole.
First folding rod 21, the second folding rod 22 include vertical walls 212,222 and symmetrical from the lower edges of vertical walls
The transverse wall 213,223 of bending out, therefore sees in shape, and vertical walls, transverse wall surround section and be square and towards side
Slot, the both ends of transverse wall extend engaging lug 211,221, the engaging lug of first folding rod one end and second folding rod one end
Engaging lug is rotatablely connected by axis, and the engaging lug of the first folding rod other end is rotated by the lateral flap on axis and a slide bar
The engaging lug of connection, the second folding rod other end is rotatablely connected by the lateral flap on axis and another slide bar.
In not ceilinged new house installation when ventilation fan, first, mounting bracket is mounted on beam：Referring to Fig. 7, figure
9, the locating plate 413 in erection part is unfolded in outward bending, and reinflated two fold bar assembly 02 to maximum rating, and two are stretched
The erection part 41 for the bottom surface and the end that the locating plate 413 of 01 one end of bar assembly is fitted in beam 06 is resisted against the side of beam 06, then
Elongation retractable rod 01 enables the erection part of the other end of retractable rod be resisted against the side of another beam and enables the positioning at the end
Piece is fitted in the bottom surface of the beam, finally passes through the fastener hole 411 in erection part to be tightened on beam with screw, that is, completes mounting bracket
Installation.
Then, ventilation fan is mounted in mounting bracket：Referring to Fig. 9, first by 52 bottom end flange 522 of duct collar component
It is fitted in the bottom surface of slide bar 13, and 52 bottom end flange 522 of duct collar component is enabled to be resisted against in positioning flange 133 from side,
The mounting hole on bottom end flange 522 is passed through with tapping screw again and be tightened on the threaded connection flanging 132 of slide bar 13, i.e., will
Duct collar component is fixed in mounting bracket.
Finally, it is the installation of babinet 51：Referring to Figure 10, the recess portion 511 and duct collar component of case body of ventilation fan side are enabled
52 correspond to, and babinet is placed in mounting hole upwards, the both sides of the edge of duct collar component 52 is enabled to be caught in recess portion 511, until air hose connects
The protrusion 521 of mouthpiece engages with the connecting hole 513 on babinet, is fixed temporarily to babinet, can unclamp hand at this time；Later with it is solid
Determine that duct collar component is the same, the mounting hole on box flange side 512 is passed through with tapping screw and is tightened in the screw thread of slide bar 13
In connection flanging 132, i.e., babinet is fixed in mounting bracket.
After the installation of furred ceiling decoration panel to be done, the panel of ventilation fan is connect with babinet, panel attachment is in furred ceiling facing
Simultaneously babinet is covered the downside of plate.
As shown in figure 11 when oneself installs ventilation fan again after installing ceiling, one is opened up on the ceiling and is slightly larger than
The opening of case body of ventilation fan.Mounting bracket is adjusted to minimum profile profile first, mounting bracket oblique cutting can be put into smallpox
Plate is open, and is unfolded to be placed on above ceiling, and then adjusting the length of retractable rod 01 keeps the length of retractable rod rigid
It is equal to the distance between adjacent two beam 06 well, mobile slide bar 13 adjusts the position of slide bar, and unfolded bar assembly 02 adjusts installation
The position in hole 03 makes ceiling opening be located in the range of mounting hole.The fastening in erection part is passed through with fixing pieces such as screws again
Hole 411 is tightened on beam, that is, completes the installation of mounting bracket.
Next installation method is identical as new house installation, and first ventilation fan is mounted in mounting bracket：By duct collar
52 bottom end flange 522 of component is fitted in the bottom surface of slide bar 13, and enable duct collar component bottom ends flange 522 from side against
In positioning flange 133, then passes through the mounting hole on flange 522 with tapping screw and be tightened in the threaded connection flanging of slide bar
On 132, i.e., duct collar component is fixed in mounting bracket.Babinet is mounted in mounting bracket again：Enable case body of ventilation fan
The recess portion 511 of side is corresponding with duct collar component 52, and babinet is placed in mounting hole upwards, enables the both sides of duct collar component 52
Edge is caught in recess portion 511, until the protrusion 521 of duct collar component engages with the connecting hole 513 on babinet, it is temporarily solid to babinet
It is fixed, hand can be unclamped at this time；Later as fixed air duct interface unit, passed through on box flange side 512 with tapping screw
Mounting hole is simultaneously tightened on the threaded connection flanging 132 of slide bar 13, i.e., babinet is fixed in mounting bracket.
Finally, the panel of ventilation fan is connect with babinet, panel attachment in the downside of furred ceiling decoration panel and covers babinet.
When specific installation, the beam as fixed position can also be keel.
Fig. 8 shows that a kind of duct collar component and the ventilation fan of babinet split settings illustrate, should when specific installation
Mounting bracket can equally install the ventilation fan that duct collar component is wholely set with babinet.
