The first connecting column, the center of the lower flange is equipped with the second threaded hole, and the upper surface of the lower flange surrounds the second spiral shell
Pit equidistant interval is equipped with multiple grooves, is equipped with the second connecting column of protrusion in the groove, second connecting column be equipped with
The inner fovea part of first connecting column cooperation, the flabellum are equipped with the location hole that cooperate with the second connecting column, the upper flange plate and
Lower flange is bolted.
As a further improvement of the above technical scheme, the shape of the groove and the shape of flabellum root match, institute
The depth for stating groove is equal to the thickness of flabellum root.
As a further improvement of the above technical scheme, first connecting column is taper pin, and the inner fovea part is cone
Connected in star.
As a further improvement of the above technical scheme, the bolt end head is equipped with hand-held part.
As a further improvement of the above technical scheme, first threaded hole is through-hole, and second threaded hole is blind
Hole.
Compared with prior art, the utility model has the beneficial effects that
1, flabellum and flange are realized quickly positioning by the cooperation of the first connecting column and inner fovea part and are pre-tightened, and further lead to
The quick connection that bolt realizes the two is crossed, installation effectiveness is substantially increased；
2, flabellum and flange are split type structure, and processing easy to produce reduces production cost.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
As shown in Figure 1, the ventilating fan blade Fast Installation structure of the present embodiment, including flange 1 and setting are on flange 1
Multiple flabellums 2.
As Figure 2-3, flange 1 includes upper flange plate 11 and lower flange 12, and the center of upper flange plate 11 is equipped with the
One threaded hole 13, the lower end surface of upper flange plate 11 are equipped with the first connecting column of multiple protrusions around 13 equidistant interval of the first threaded hole
14；The center of lower flange 12 is equipped with the second threaded hole 15, between the upper surface of lower flange 12 surrounds the second threaded hole 15 equidistantly
Every equipped with multiple grooves 16；The second connecting column 17 of protrusion is equipped in groove 16, the second connecting column 17 is equipped with and the first connecting column
The inner fovea part 18 of 14 cooperations；Flabellum 2 is equipped with the location hole 19 cooperated with the second connecting column 17.
Wherein, the first threaded hole 13 is through-hole, and 15 hole of the second screw thread is blind hole, and bolt 3 sequentially passes through the first threaded hole 13
