31, size of the latch 31 along the length bearing of trend of blade 30 on the same side of blade 30 is less than the length that blade 30 extends
With the ratio of the quantity of latch 31, that is to say, that the length of blade 30 and the ratio positioned at the quantity of latch 31 on the same side of blade 30
Value is greater than the size that the latch 31 of the homonymy of the blade 30 extends along the length direction of blade 30, so, positioned at the homonymy of blade 30
Latch 31 it is arranged spaced apart on the length direction of the blade 30, ensure connection reliability, saved production cost.
As shown in Figure 4 and Figure 5, it is respectively disposed with front shroud 10 and back shroud 20 and inserts 31 pins 31 with the both sides of blade 30
Corresponding pin-and-hole 10b, because blade 30 is arranged in the shape of a spiral, multiple latches 31 are arranged at intervals in the homonymy of blade 30, front shroud
10 and back shroud 20 on pin-and-hole 10b also formed corresponding to helical form be intervally arranged, realize blade 30 and front shroud 10 and back shroud
20 pin connection.
It should be noted that after blade 30 installs with front shroud 10 and back shroud 20, a side of blade 30 is with before
The inner surface fitting of cover plate 10, another side of blade 30 is bonded with the inner surface of back shroud 20, compact-sized.
According to the utility model further embodiment, thickness of the latch 31 in the circumference of wind wheel 100 on blade 30 is small
In the thickness equal to blade 30 in the circumference of wind wheel 100, it is more than along the thickness of the circumferential blade 30 of wind wheel 100 and is located at the blade
The thickness of latch 31 on 30 so that the structure of latch 31 is lighter, beneficial to the pin-and-hole 10b on front shroud 10 and back shroud 20
It is engaged.
Alternatively, fastener 40 is also equipped with back shroud 20, fastener 40 is fixedly connected with back shroud 20, is being fastened
There is axle position hole 40a, axle position hole 40a to be connected with drive shaft for driving wind wheel 100 to rotate for the middle position of part 40.
