Traditional through-flow fan blade in use in place of Shortcomings, fix, can not be adjusted by length, this
Aspect causes it that cannot match with the air duct of different length, poor for applicability；On the other hand it can not quickly open to air duct
It is cleared up, can only be carried out by modes such as demounting bolts, it is cumbersome.
Summary of the invention
It is an object of the invention to overcome the above-mentioned problems in the prior art, a kind of length-adjustable through-flow wind is provided
Leaf.
To realize above-mentioned technical purpose and the technique effect, the present invention is achieved through the following technical solutions:
A kind of length-adjustable through-flow fan blade, the through-flow fan blade are three stage structure, the blade sleeve group including being located at middle part
Part and wind acanthus leaf component positioned at both ends, the blade sleeve component is by the blade sleeve of rounded array distribution and set on its both ends
Connection ring is constituted, and the wind acanthus leaf component is constituted by the wind acanthus leaf of rounded array distribution and set on the connection ring of one end, institute
The quantity for stating blade sleeve and wind acanthus leaf corresponds, and the inward at both ends of the blade sleeve offers the card slid into convenient for wind acanthus leaf
Slot, interior be equipped with of the card slot squeeze spring.
Further, the length of the wind acanthus leaf is greater than the length of blade sleeve.
Further, the connection ring with where it blade sleeve or wind acanthus leaf be structure as a whole.
Further, the blade sleeve component and wind acanthus leaf component are molded by plastic material.
Further, the both ends vallecular cavity diameter of the card slot is wider than middle part vallecular cavity diameter.
Further, extruding spring there are two being set in each card slot, the two of the diameter for squeezing spring and card slot
End slot chamber diameter matches.
The beneficial effects of the present invention are:
Structure of the invention design is reasonable, by the way that through-flow fan blade to be set as by blade sleeve component and be located at its both ends fan blade board group
The three stage structure that part is constituted, the wind acanthus leaf of wind acanthus leaf component the card slot of blade sleeve end can be slided along blade sleeve component
It is dynamic, to realize the adjusting of through-flow fan blade entire length, be also convenient for through-flow fan blade being installed into air duct, when need to air duct into
Row cleaning is shunk through-flow fan blade with fast quick-detach by sliding, and it is convenient to operate.
Certainly, it implements any of the products of the present invention and does not necessarily require achieving all the advantages described above at the same time.
