Abstract
The present invention discloses a kind of fixed structure adjusted with blade radial size and rotational angle, and interconnecting piece is arranged in the lower section of blade, and the interconnecting piece includes convex ring and lower convex ring, is footstalk between convex ring and lower convex ring；In the convex ring insertion blade, the lower convex ring is arranged in the respective slot of wheel hub；Wheel cap is also provided with corresponding groove, and wheel cap is corresponding with the groove of wheel hub to fasten the lower convex ring, and wheel cap is bolted on wheel hub；Wheel hub and wheel, which cover, is respectively provided with strip groove corresponding with footstalk；The outboard shafts of the footstalk set up convex ribs；Multigroup groove is disposed radially on the wheel hub and wheel cap.It is an advantage of the invention that：As a result of multigroup groove structure corresponding with lower convex ring is disposed radially, radial adjustment can be carried out as needed；And utilize the convex ribs of footstalk corresponding with the convex ribs of strip groove, it can limit and receive external force influence after blade angle is fixed and rotate；And the rotational angle of blade can arbitrarily be set, and adapt to a variety of demands.
Description
Technical field
The present invention relates to blade, the fixed structure of specifically a kind of blade and wheel hub.
Background technology
Blade is common mechanical part.When in use, it is sometimes desirable to the rotational angle and length of blade are adjusted,
To change exhaust air rate or to coincide with the internal diameter of air exhaust passage.Existing blade is fixed structure, especially the diameter of blade
It is fixed to length, this just cannot achieve adjustment function.
Invention content
In order to solve the above-mentioned technical problem, the object of the present invention is to provide one kind having blade radial size and rotational angle
Interconnecting piece is arranged in the lower section of the fixed structure of adjusting, blade, and the interconnecting piece includes convex ring and lower convex ring, and convex ring is convex under
Interannular is footstalk；In the convex ring insertion blade, the lower convex ring is arranged in the respective slot of wheel hub；Wheel cap is also provided with phase
The groove answered, wheel cap is corresponding with the groove of wheel hub to fasten the lower convex ring, and wheel cap is bolted on wheel hub；Wheel hub with
Wheel, which covers, is respectively provided with strip groove corresponding with footstalk；The outboard shafts of the footstalk set up convex ribs；The wheel hub and wheel cap
On be disposed radially multigroup groove.
Another wheel hub structure is：The wheel hub is two groups of concentric structures, wheel hub setting and the footstalk pair in outside
The strip groove answered, setting groove corresponding with lower convex ring on the wheel hub of inside.
Convex ribs are arranged in inside for the fixation for ensureing after blade adjusts the angle, the strip groove.In this way, strip groove with
After footstalk contact, due to the limitation of convex ribs, the rotational angle of blade will not change.
In the present invention, the material of blade is preferably carbon fiber.
It is an advantage of the invention that：It, can basis as a result of multigroup groove structure corresponding with lower convex ring is disposed radially
It needs to carry out radial adjustment；And utilize the convex ribs of footstalk corresponding with the convex ribs of strip groove, it can limit after blade angle is fixed and receive
It influences and rotates to external force；And the rotational angle of blade can arbitrarily be set, and adapt to a variety of demands.

Fig. 2 is the structural schematic diagram of wheel hub；
Fig. 3 is the cooperation schematic diagram of wheel cap and wheel hub；
Fig. 4 is the structural schematic diagram of another wheel hub.
Specific implementation mode
The present invention is illustrated below in conjunction with the accompanying drawings, as shown, interconnecting piece, the interconnecting piece is arranged in the lower section of blade 1
It is footstalk 3 including convex ring 2 and lower convex ring 4, between convex ring 2 and lower convex ring 4；The outboard shafts of the footstalk 3 set up convex ribs
5；The convex ring 2 is embedded in blade, and the lower convex ring 4 is arranged in the respective slot 7 of wheel hub 6；Wheel cap 8 is also provided with accordingly
Groove, wheel cap 8 is corresponding with the groove of wheel hub 6 to fasten the lower convex ring, and wheel cap 8 is fixed on by bolt 10 on wheel hub 6；Wheel hub
6 and wheel cap 8 on be respectively provided with strip groove corresponding with footstalk 9；Multigroup groove 7 is disposed radially on the wheel hub and wheel cap.
Another wheel hub structure is：The wheel hub is two groups of concentric structures, the setting of outside wheel hub 61 and footstalk pair
The strip groove 9 answered, corresponding with the lower convex ring groove of setting 7 on inside wheel hub 62.Inside wheel hub and outside wheel hub pass through spoke
61 connections.
Convex ribs are arranged in inside for the fixation for ensureing after blade adjusts the angle, the strip groove 9.In this way, strip groove 9
After being contacted with footstalk 3, due to the limitation of convex ribs, the rotational angle of blade 1 will not change.
In the present invention, the material of blade is preferably carbon fiber.
