Utility model content
Technical problem to be solved in the utility model is to provide a kind of easy-to-dismount range hood impeller installing.
The utility model solves the technical scheme that its technical problem adopts: this range hood impeller installing comprises drive motors, the wheel hub be fixedly connected with impeller, the output shaft of described drive motors is connected with turning cylinder, described turning cylinder is arranged with taper sheath, the bigger diameter end of described taper sheath is towards drive motors, the interior hole size of described taper sheath and turning cylinder match, the center mounting hole of described wheel hub is bellmouth, the bigger diameter end of described bellmouth is towards drive motors, the size of described bellmouth and the male cone (strobilus masculinus) of taper sheath match, described wheel hub is set on taper sheath, the hole wall of described bellmouth is provided with the first keyway, sidewall on described taper sheath is provided with keyhole, the surface of described turning cylinder is provided with the second keyway, connecting key is provided with in described keyhole, the both sides of described connecting key are stuck in the first keyway and the second keyway, described rotation the tip of the axis is provided with hold-down nut.
Further, be provided with disc spring between described hold-down nut and taper sheath, the external diameter of described disc spring is greater than the miner diameter end diameter of bellmouth.
Further, the angle of the male cone (strobilus masculinus) of described taper sheath and the central axis of taper sheath is 3-10 degree.
Further, the angle of the male cone (strobilus masculinus) of described taper sheath and the central axis of taper sheath is 5 degree.
Further, the length of described taper sheath is less than the length of bellmouth.
The beneficial effects of the utility model are: this range hood impeller installing is when dismantling, only the hold-down nut that turning cylinder end is arranged need be taken off, center mounting hole due to wheel hub be bellmouth and the bigger diameter end of bellmouth towards drive motors, simultaneously turning cylinder is arranged with taper sheath and the bigger diameter end of taper sheath towards drive motors, use hand wobble impeller, due to the existence of the conical surface, wheel hub just can the very smooth conical surface landing along taper sheath, after impeller cleaning, only the installing hole of wheel hub need be set on taper sheath and then tighten hold-down nut, due to the existence of the conical surface, can very smoothly wheel hub be set on taper sheath, without the need to special extracting tool, dismantle and install all very convenient, dismantle impeller to user and bring great convenience.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model range hood impeller installing;
Be labeled as in figure: drive motors 1, wheel hub 2, turning cylinder 3, taper sheath 4, installing hole 5, connecting key 6, hold-down nut 7, disc spring 8.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, this range hood impeller installing comprises drive motors 1, the wheel hub 2 be fixedly connected with impeller, the output shaft of described drive motors 1 is connected with turning cylinder 3, described turning cylinder 3 is arranged with taper sheath 4, the bigger diameter end of described taper sheath 4 is towards drive motors 1, interior hole size and the turning cylinder 3 of described taper sheath 4 match, the installing hole 5 at described wheel hub 2 center is bellmouth, the bigger diameter end of described bellmouth is towards drive motors 1, the size of described bellmouth and the male cone (strobilus masculinus) of taper sheath 4 match, described wheel hub 2 is set on taper sheath 4, the hole wall of described bellmouth is provided with the first keyway, sidewall on described taper sheath 4 is provided with keyhole, the surface of described turning cylinder 3 is provided with the second keyway, connecting key 6 is provided with in described keyhole, the both sides of described connecting key 6 are stuck in the first keyway and the second keyway, the end of described turning cylinder 3 is provided with hold-down nut 7.This range hood impeller installing is when dismantling, only the hold-down nut 7 that turning cylinder 3 end is arranged need be taken off, center mounting hole 5 due to wheel hub 2 be bellmouth and the bigger diameter end of bellmouth towards drive motors 1, simultaneously turning cylinder 3 is arranged with taper sheath 4 and the bigger diameter end of taper sheath 4 towards drive motors 1, use hand wobble impeller, due to the existence of the conical surface, wheel hub 2 just can the very smooth conical surface landing along taper sheath 4, after impeller cleaning, only the installing hole 5 of wheel hub 2 need be set on taper sheath 4 and then tighten hold-down nut 7, due to the existence of the conical surface, can very smoothly wheel hub 2 be set on taper sheath 4, without the need to special extracting tool, dismantle and install all very convenient, dismantle impeller to user and bring great convenience.
