Further, multiple blades that each commutation blade comprises body and extended radially outward by this body periphery.
Further, this tangent plane is the plane that is parallel to this rotatingshaft axis, and this locking face and this faying surface are plane and are parallel to this tangent plane
Further, this tangent plane extends to the end face of this fixed end.
Further, this reinforcer is formed on the tangent plane of this rotatingshaft by insert molding.
Further, this fastening piece comprises head and is coaxially arranged at the bar portion of this head one side, and this bar portion is arranged in this locking hole and locking hole, and this head is held in the locking face of this reinforcer.
Further, this fastening piece is metal screw, and this locking hole and this locking hole are tapped hole, and this bar portion wears and is screwed together in this locking hole and locking hole.
Because fastening piece forces on rotatingshaft by reinforcer, by contacting of faying surface and tangent plane, disperse fastening piece to put on the stress on rotatingshaft, make this commutation impeller not fragile.
Brief description of the drawings
Fig. 1 is the schematic perspective view of the utility model commutation impeller fixed structure.
Specific embodiment
Below in conjunction with drawings and Examples, commutation impeller fixed structure of the present utility model is described in further detail.
Refer to Fig. 1, commutation impeller fixed structure 100 of the present utility model comprises impeller 10, is installed in the reinforcer 30 on impeller 10, and fastening piece 50.Fastening piece 50 is arranged on reinforcer 30 and impeller 10, and is locked in fixed component (not shown), thereby by fixing impeller 10.
Impeller 10 comprises rotatingshaft 11 and is arranged at intervals at the multiple commutation blades 13 on rotatingshaft 11.Rotatingshaft 11 one end protrude from a side of multiple commutation blades 13 and form fixed end 111.On fixed end 111, be recessed to form tangent plane 1111 and on tangent plane 1111, offer locking hole 1113.Tangent plane 1111 is for being parallel to the plane of rotatingshaft 11 axis, and locking hole 1113 radially connects fixed end 111.Multiple blades 133 that each commutation blade 13 comprises body 131 and extended radially outward by body 131 peripheries.In the present embodiment, each commutation blade 13 comprises three blades 133.In the present embodiment, locking hole 1113 is tapped hole, and impeller 10 is made up of plastic material.Be appreciated that tangent plane 1111 can extend to the end face of fixed end 111.
In the present embodiment, reinforcer 30 is direction block shape, and its laminating is arranged on the fixed end 111 of rotatingshaft 11.Reinforcer 30 is made for panel beating, and it comprises the locking face 31 and the faying surface 33 that are oppositely arranged.In one embodiment, locking face 31 is plane and is arranged in parallel with faying surface 33.Reinforcer 30 connects locking face 31 and offers locking hole 35 with faying surface 33.In the present embodiment, locking hole 35 is tapped hole or through hole.Be appreciated that reinforcer 30 also can be formed on rotatingshaft 11 by insert molding.In alternate embodiment, in order to increase the area of contact between faying surface 33 and tangent plane 1111, the tangent plane 1111 on tangent plane 1111 and the fixed end 111 of this reinforcer 30 can be arc-shaped curved surface.
Fastening piece 50 comprises head 51 and is coaxially arranged at the bar portion 53 of head 51 1 sides.In the present embodiment, fastening piece 50 is metal screw.
When assembling, the faying surface of reinforcer 30 33 is fitted and is arranged on the tangent plane 1111 of rotatingshaft 11 abreast, and locking hole 35 is aimed to the locking hole 1113 on rotatingshaft 11.The bar portion 53 of fastening piece 50 is worn and is screwed together in locking hole 35 and locking hole 1113, and the tip lock of bar portion 53 is bonded on fixed component.Now, its head 51 is held on the locking face 31 of reinforcer 30, thereby impeller 10 is fixed on fixed component.
Because the head 51 of fastening piece 50 forces on rotatingshaft 11 by reinforcer 30, it contacts by faying surface 33 and tangent plane 111, has disperseed fastening piece 50 to put on the stress on rotatingshaft 11, makes the fixed end 111 of impeller 10 not fragile.Further, in order to increase the frictional force between head 51 and the locking face 31 of fastening piece 50, this locking face 31 has certain roughness.
Be appreciated that locking hole 35 and locking hole 1113 can be not also tapped hole, and be through hole.Now, fastening piece 50 is locked on fixed component after being arranged in locking hole 35 and locking hole 1113.
In sum; although the utility model discloses as above with embodiment; so it not only limits the utility model; any Professional visitors; in the situation that not departing from essence of the present utility model; the utility model is done to various changes and retouching, all should be included in the utility model scope required for protection.
