Specific implementation mode：
Embodiment one：Present embodiments provide a kind of fan blade location structure, below with reference to attached drawing to the embodiment make into
The detailed description of one step.
It is a kind of fan blade location structure as shown in Figure 1 to Figure 2, which includes fan blade 2, is installed in fan blade 2
Axle sleeve 3, and be arranged in the shaft 1 of axle sleeve 3.Fan blade 2 is set in by axle sleeve 3 in shaft 1, and axle sleeve 3 and the cooperation of shaft 1 can
Fan blade 2 is transmitted and gives into action edge to be accurately positioned.Fan blade 2 is metal fan blade in the present embodiment, and in order to mitigate complete machine weight
Amount, preferably aluminum fan blade.
As shown in Figure 3 to Figure 4, axle sleeve 3 includes a torque transfer part 31, determines positioned at the first of 31 side of torque transfer part
Position portion 32 and the second positioning region 33 positioned at 31 other side of torque transfer part, torque transfer part 31, the first positioning region 32 and
Two positioning regions 33 are coaxially disposed.In the present embodiment, in order to simplify technique, by the first positioning region 32, torque transfer part 31 and second
Positioning region 33 is wholely set, and the 3 preferred plastic material of axle sleeve, easy to produce and lighter in weight.Wherein, in order to be transmitted in torque
Tend to be uniform in the process and stablize, the mating surface of torque transfer part 31 and fan blade 2 is regular polygon, and the present embodiment uses positive six side
Shape, for the ease of installing and positioning, the first positioning region 32, the second positioning region 33 and the mating surface of fan blade 2 are circle.Equally
For the ease of installation, the outer diameter of the first positioning region 32 is more than the outer diameter of torque transfer part 31, and the outer diameter of torque transfer part 31
More than the outer diameter of the second positioning region 33.
As shown in Figure 5 to Figure 6, the hollow-out parts 21 that fan blade 2 is equipped with and axle sleeve 3 coordinates, which is equipped with passes with torque
It passs the regular hexagon hollow out 211 of the cooperation of portion 31, determine with the first cylinder hollow out 212 of the first positioning region 32 cooperation and with second
The second cylinder hollow out 213 that position portion 33 coordinates, the first cylinder hollow out 212, regular hexagon hollow out 211 and the second cylinder are engraved
Sky 213 is disposed adjacent successively.And corresponding to axle sleeve 3, the outer diameter of the first cylinder hollow out 212 is more than positive hexagonal column hollow out
211 outer diameter, 211 outer diameter of positive hexagonal column hollow out are more than the outer diameter of the second cylinder hollow out 213.In this way, can install
When by axle sleeve 3 embedded in fan blade 2 hollow-out parts 21 in.
In addition, as shown in figure 3,3 both ends of axle sleeve are respectively equipped with protruding portion：Head 321 positioned at 32 side of the first positioning region
And the tail portion 331 positioned at 33 side of the second positioning region.The setting of head 321 and tail portion 331 is so that the axial length of axle sleeve 3 is big
In the axial length of hollow-out parts 21, it is convenient for the installation and removal of axle sleeve 3.Axle sleeve 3 further includes the through-hole 34 coordinated with shaft 1, and
34 one end of through-hole is equipped with antislip ring 35.Antislip ring 35 has elasticity, and material can be rubber, one kind in silica gel, in the present embodiment
For rubber antiskid circle.The setting of antislip ring 35, is convenient for the installation of axle sleeve 3 and shaft 1, and can enhance between axle sleeve 3 and shaft 1
Tightness.Meanwhile in order not to increase the whole heavy burden of axle sleeve 3, axle sleeve 3 is located at head end and is uniformly provided with hollow-out parts radially
36。
Therefore in the fan blade location structure, the first positioning region 32 and the second positioning region 33 are located at 31 both sides of torque transfer part, and
Respectively obtain the support of the first cylinder hollow out 212 and the second cylinder hollow out 213.Axle sleeve 3 utilizes the first positioning region 32 and the
Two positioning regions 33 make shaft 1 form simply supported beam, to which fan blade 2 is supported and is accurately positioned.31 He of torque transfer part simultaneously
Regular hexagon hollow out 211 coordinates, and torque is transmitted by mating surface, though 31 precision of torque transfer part is not very high, or in length
It is worn after long use, will not make excessively to loosen between axle sleeve 3 and fan blade 2, also be avoided that fan blade is made in rotation process
Complete machine is kept to operate steadily at the vibration of complete machine.Therefore, the use of the fan blade location structure can reduce in axle sleeve 3 and fan blade 2
The requirement on machining accuracy and difficulty of processing of hollow-out parts 21 are easy to control in technique, and can prolong the service life.
Embodiment two：A kind of blower is present embodiments provided, is a kind of garden tool set, for clearing up fallen leaves.This blows
Suction machine includes the fan blade location structure as described in embodiment one, which specifically please refers to attached drawing 1 to 6.
By using the fan blade location structure as described in embodiment one in the present embodiment, the fan blade in the blower can be made fixed
Bit architecture required precision is low, and difficulty of processing is low, is easily controlled in technique, to effectively reduce cost, and the structure can to fan blade into
Row is accurately positioned, and when work can effectively reduce vibration amplitude when fan blade rotation, and blower is made to operate steadily.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also considered as
Protection scope of the present invention.
