The upper end of cross bar 6 is fixed at end, and the top of electric pushrod 15 welds or is fixed with fixed block 16 by screw, fixed block 16
Top has been connected by screw to fixed link 17, and the inner wall of barrier frame 11 is fixedly welded with barrier 18, and obstructs the inner sidewall of frame 11
On be welded with fan 19.Due to barrier frame 11 the inside of subtube 9 as stop so that barrier frame 11 at air-flow lead to
Row space moment reduces, and utilizing " valley effect ", (when air-flow flows into valley by opening, atmospheric density is compressed, wind speed
Just increase, air can accelerate to flow through valley.) principle air-flow is accelerated by flow velocity when barrier frame 11, while again by fan
Flow velocity is accelerated in the 19 inside air blast of rotation together.It will be obstructed between frame 11 and subtube 9 and welded together by weldment 10, it can
It is not in the case where shaking is collapsed that the structure is effectively ensured in use, and structure obstruction subtube 9 is caused normally to be divulged information；
First Air Filter 3 is fixedly installed in fixed frame 2, and fixed frame 2 and main air hose 1 are Detachable connection structure.Gu
The outer wall surrounding of frame 2 is determined through there is screw, and the first Air Filter 3 is welded on fixed frame 2, to make fixed frame 2 and first dust-proof
Net 3 is bonded to each other, and is then screwed to fixed frame 2 on the installation trunnion 4 of main 1 inner sidewall of air hose and is fastened by screw again,
And fixed frame 2 and main air hose 1 are dismountable screw connecting structure, facilitate later period disassembly cleaning, fixed frame 2 and the first Air Filter
3 play good protective action, can effectively ensure that in ventilation process, and upper end sundries will not fall into entire wind from main air hose 1
In guard system, while when user needs to carry out deashing to the fixed frame 2 in the main air hose 1, user can be by backing out
Fixed frame 2 is taken out out of main air hose 1, is cleared up convenient for user 3 surface of the first Air Filter by screw；
The width of cross bar 6 is greater than the width of main air hose 1, and cross bar 6, postive stop baffle 13 and 14 three of gag lever post can pass through spiral shell
Nail or the mode of welding are connected as one.Two groups of electric pushrods 15 are symmetrical along the vertical central axes of cross bar 6.Cross bar 6, limit
The wind shielding structure of baffle 13 and gag lever post 14 as whole equipment, is all made of stainless steel material and is made, be not susceptible in use

It flows into subtube 9, while fixed link 17 is fixedly connected by screw with ceiling, can effectively ensure that electric pushrod 15 is being drawn
When stretching, operate normally.
The upper end two sides of cross bar 6 are fixed with electric pushrod 15, and the top of electric pushrod 15 by welding or is bolted
Fixed link 17 has been bolted in fixed block 16, the top of fixed block 16, obstructs and is installed by welding with barrier on the inner wall of frame 11
18, and the inside for obstructing frame 11 is fixed with fan 19 by screw, fan 19 is conllinear with the barrier central axis of frame 11, works as air
When flowing into 9 inside of subtube, since barrier frame 11 reduces pipeline inner space, so that air-flow velocity is accelerated, while again by wind
The 19 inside air blast of rotation of fan, can effectively accelerate the air velocity in the region, while obstructing the barrier 18 in frame 11 and playing well
Buffer action, it is possible to reduce the being of some similar mouse climbs into subtube 9 and main air hose 1, prevent its to subtube 9 with
Main air hose 1 is destroyed, and unnecessary loss is brought.Electric pushrod 15 and fan 19 and external controller are electrically connected, and are had
Peripheral control unit controls its operation, and electric pushrod 15 and fan 19 are the prior art, can be selected according to actual working condition
Type, selection method are also the prior art.
Working principle: unlatching central hollow is passed through first for this kind of multisection type ventilation duct structure for central air-conditioning
It adjusts, air is flowed into out of main air hose 1, then by passing through in fixed frame 2 and the first Air Filter 3, at this time when user needs to be in charge of
It when road 9 is opened, is controlled by peripheral control unit and opens electric pushrod 15, electric pushrod 15 drives cross bar 6 to be pulled up, sliding block 7
Inner wall along sliding rail 8 moves up, and subtube 9 is in opening state, and air flows into subtube 9 from main air hose 1, then works as air stream
Enter inside subtube 9, then user is controlled by controller further according to needs and opens the inside air blast of corresponding fan 19, Neng Gouyou
Effect accelerates the air velocity in the region, while obstructing the barrier 18 in frame 11 and playing good buffer action, completes like this whole
The use process of a multisection type ventilation duct structure for central air-conditioning.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
