Air intake vent coordinates.
Wherein oil network 3 is towards a hanging plate 4 is installed with the side of blower fan, and the hanging plate 4 is in double-deck list structure, the double strip
The space that shape structure is included between the spaced laminate 43 of first laminate 42 and second up and down, first and second laminate can be rotating shaft
The rotation of axle cap provides space, and first laminate in oil network and the first laminate away from offering a positioning through hole 41.Air duct board 1
A Quick-dismantle component 5 is installed with upper correspondence hanging plate 4, positioning is provided with a rotating shaft 51, the end shape of the rotating shaft on the Quick-dismantle component 5
Cheng Youyi axle caps 511, rotating shaft is interspersed in positioning through hole 41 and axle cap 511 is hooked at positioning through hole, positioning through hole 41 and institute
State the form fit of axle cap 511 of rotating shaft and be able to only hold axle cap in one direction and intert into.The direction of second laminate 43
Dome 44 is provided with the position at the correspondence center of axle cap 511 on the side of first laminate, the design of the dome can make rotating shaft
The frictional force being subject to axle cap is reduced during spinning when being under pressure.In addition, the rotating shaft 51 can when depressed
Turn side around its center axis sidespin to stretch.
Quick-dismantle component 5 also includes back box 52 and the upper lid 53 supporting with the back box, and the bottom of the side outwardly of back box 52 is fixed
There is a support 6, the support is threadedly connected on air duct board 1.The back box 52 is installed with a positioning rod 521 on side inwardly,
The end sleeve of the locating rod is sheathed on the spring 54 provided with a spring 54 for being higher by locating rod, rotating shaft 51, and its concrete structure is：
The lower end edge of the locating rod 521 is axially arranged with the card stupefied 522 of some length unanimously, and spring 54 is sheathed on locating rod and backstop
It is higher than the top of locating rod in the top at the stupefied place of the card, and the spring.
What the tail end of the rotating shaft 51 circumferentially offered a circular arc rises as high as the banks 512, and from rotating shaft tail end bottom spiral to
Upper extension offers a spin slot 513, and spin slot 513 is a quarter from spin slot tail end bottom to the circumferential distance between spin slot top
Week, and the spin slot 513 is with rising as high as the banks 512 without joining.
The track pad 56 in back box is movably positioned at provided with a seesaw 55 and one, the bottom of the track pad 56 is movably equipped with one
Strutbeam 562, the strutbeam is fixed in back box 52, and track pad (56) can be swung around the strutbeam.In addition offered on track pad
Heart-shaped track groove 561, one end fixing card of seesaw 55 is risen as high as the banks at 512 located at described, and the seesaw other end is arranged in heart-shaped track
It can slide in groove 561 and in heart-shaped track groove；One is offered on the upper lid 53 at correspondence locating rod 521 to stretch for rotating shaft 51
The through hole 531 of contracting, the through-hole wall, which is located at via openings lower section, is installed with a salient point 532 matched with spin slot, and the salient point exists
The spinning of rotating shaft 51 can be driven in rotating shaft telescopic process.
Seesaw 55 includes a card hand 551, and one end of card hand, which is divided on two forks, and the two forks opposite side, is respectively formed with one
Axis 552, the axis is arranged in the rising as high as the banks in 512 of rotating shaft；The card hand other end is installed with a pole being fixed in back box
553, a slide bar 554 is articulated with the pole, the other end of the slide bar is provided with a sliding axle 555, and the sliding axle can be along rail
The heart-shaped track groove 561 of mark plate is slided.
When being fixed using the installation that there is telescopic rotary type quick-disassembly structure to carry out oil screen of smoke exhaust ventilator, first by oil network 3
In the neck 21 of the insertion medium frame plate 2 of card key 31 of one end (such as Figure 12), the other end of oil network 3 is then pushed down with hand push and (is provided with
One end of Quick-dismantle component 5), the axle cap 511 of now rotating shaft 51 and the form fit of positioning through hole 41 and only in one direction can
Enough enter positioning through hole 41, then axle cap enters in positioning through hole 41 and contradicted with the second laminate 43, because spring 54 is now in
The elongation state then stress of rotating shaft 51 and extrusion spring 6 so that spring 6 compresses that (but compression completely still has certain row of shrinking back
Journey), then it is fixed after rotating shaft is shunk back, while the spin of rotating shaft 51 is turn 90 degrees during shrinking back, then the concomitant rotation of axle cap 511,
Caught at positioning through hole 41 in the first laminate 41, so that oil network is fixed.When needing dismounting oil network, in above-mentioned state
On the basis of, then pushing one end that oil network is provided with Quick-dismantle component, then rotating shaft, which departs from, fixes, and is extended simultaneously certainly using the elastic force of spring 6
Derotation is turn 90 degrees, and axle cap turns to the state with the form fit of positioning through hole 41, now lucky the determining from the first laminate 42 of axle cap
Spun off in the through hole of position, so as to reach the purpose of dismounting oil network.Axle cap can with hanging plate location diagram under above two state
Referring to Figure 10 and Figure 11.
Track pad, seesaw and the annexation figure of rotating shaft are shown in Figure 5.Axis 552 in the card hand 551 of seesaw 55 blocks
Firmly rotating shaft 51 rises as high as the banks 512, and the position of pole 553 of seesaw is fixed in back box 52, the sliding axle 555 on the slide bar 554 of seesaw exists
In the heart-shaped track groove 561 of track pad.
When initial position (i.e. rotating shaft be in elongation state), the slip shaft end of the then seesaw slide bar 554 of rotating shaft 51 is pushed
Upwarp, sliding axle 555 is slided in the heart-shaped track groove of track pad.When sliding axle reaches the groove heart position of heart-shaped track groove
When sliding axle be locked inactive (i.e. shown in Fig. 4), now seesaw is fixed, so that rotating shaft is fixed, position of reaching home.
Salient point 532 on the spin slot 513 and upper lid 53 of rotating shaft coordinates the spinning movement for completing rotating shaft, i.e., when rotating shaft is compressed, due to
Salient point is acted on, and is caused rotation spin slot to be trackslipped along salient point, is then driven axis of rotation, and because spin slot 513 is from spin slot tail end bottom
It it is a quarter week to the circumferential distance between spin slot top, then when reaching final position from initial position, rotating shaft rotates just
90 degree.
When in final position when (rotating shaft is in compressive state), when pushing rotating shaft again, the sliding axle of slide bar 554 takes off
From the groove heart position of heart-shaped track groove on track pad, now because the back stretch of spring is acted on so that rotating shaft 51 extends, then sticks up
The end of sliding axle 555 of the slide bar of plate 55 is moved down, and slide bar is slided again along heart-shaped track groove, then strutbeam of the track pad along track pad
562 swing, and Quick-dismantle component reaches initial position, and now the limit point of whole Quick-dismantle component is as shown in Figure 3.Rotating the whole of elongation
During individual, the mating reaction of salient point 532 and spin slot 513 is also due to, causes the spin slot of rotating shaft to be arrived along salient point by backtracking
Initial position.
