It is at orifice.Under such configuration, during axial-flow leaf horizontal positioned, blade outer rim directly contact face easily causes the damage of blade
It is bad, scrap.
The content of the invention
In order to solve the above problems, the purpose of this utility model is to provide a kind of axial-flow leaf, and the axial-flow leaf can be
Blade outer rim directly contact face is avoided during placement, so as to evade blade due to placing the damage that reason is caused.
In order to realize above-mentioned purpose, the utility model employs following technical scheme：
A kind of axial-flow leaf, including shaft sleeve part, and the multiple axle stream leaves being fastened on the face of shaft sleeve part outer circumferential
Piece；The air-out end of the axial blade exceeds the axial end of shaft sleeve part, and the axial height beyond position is H1；Its feature
It is：The axial blade and the connecting portion of shaft sleeve part are provided with platform, and platform protrudes from the axial end of shaft sleeve part, prominent
The axial height at position is H2, and H2 is more than H1.
Preferably, the platform includes the first platen being arranged on the axial end of shaft sleeve part, and it is arranged on axle
Flow the second platen on blade inner end；First platen is connected with the second platen, the support end face of the first platen and
The support end face of two platens is flush.
Preferably, first platen is the curved support plate set along shaft sleeve part circumferential edge, the second platen is one
Body is connected to the supporting plate in the middle part of arc lateral surface.Such scheme provides a kind of concrete structure of platform, and the platform uses T
The section support of shape structure, with the high advantage of supporting ＆ stablizing, intensity.
Preferably, the shaft sleeve part is torus, the middle part of shaft sleeve part is provided with axis hole.
Preferably, the first platen arc length W is the 1/4 ~ 1/3 of shaft sleeve part diameter d；First plate thickness D1 and second
Platen thickness D2 is equal and equal to the 1/10 of the first platen arc length W；H2-H1 >=the 5mm.
The utility model uses above-mentioned technical proposal, and the technical scheme is related to a kind of axial-flow leaf, in the axial-flow leaf
Axial blade and the connecting portion of shaft sleeve part are provided with platform, and the height H2 of the platform exceeds more than the air-out end of axial blade
The axial height H1 of shaft sleeve part；In axial-flow leaf horizontal positioned, platform is directly contacted with bottom surface, and makes the height of axial-flow leaf
Lifting, the air-out end of axial blade can not contacted vacantly with ground, so as to avoid blade outer rim directly contact face, evade leaf
Piece is due to placing the damage that reason is caused.
Brief description of the drawings

Fig. 2 is axial plane schematic diagram of the present utility model.
Fig. 3 is horizontal positioned schematic diagram of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings, preferred embodiment of the present utility model is described in further detail.
A kind of axial-flow leaf as shown in Fig. 1 ~ 3, including shaft sleeve part 1, and it is fastened on the outer circumferential face of shaft sleeve part 1
On multiple axial blades 2, the shaft sleeve part 1 is torus, and the middle part of shaft sleeve part 1 is provided with axis hole.The axial blade 2 goes out
Wind end 21 exceeds the axial end of shaft sleeve part 1, and the axial height beyond position is H1.The axial blade 2 and shaft sleeve part 1
Connecting portion be provided with platform 3, platform 3 protrudes from the axial end of shaft sleeve part 1, and the axial height of protruding parts is H2, H2
More than H1, preferably H2-H1 >=5mm.
Specifically, the platform 3 includes the first platen 31 being arranged on the axial end of shaft sleeve part 1, and is arranged on
The second platen 32 on the inner end of axial blade 2.First platen 31 is connected with the second platen 32, the branch of the first platen 31
The support end face of support end face and the second platen 32 is flush.First platen 31 is the arc set along the circumferential edge of shaft sleeve part 1
Shape supporting plate, the second platen 32 is to be integrally connected to the supporting plate in the middle part of arc lateral surface.Such scheme provides a kind of flat
The concrete structure of platform 3, the platform 3 is supported using the section of T-shaped structure, with the high advantage of supporting ＆ stablizing, intensity.Further
