Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in drawings, fan rotor of the present invention, comprises housing 1, motor and motor output shaft 2.Because described motor (not shown) is loaded in housing 1, therefore do not show the overall structure of motor.The upper surface of described housing 1 is provided with the through hole (unmarked) that power supply machine output shaft 2 stretches out; the edge of this through hole is also provided with protection motor output shaft lower end motor body 3 and guide sleeve 4 protruding upward, forms an annular interpolation slit 5 between this guide sleeve 4 and motor output shaft lower end motor body 3.
Unlike the prior art; it also comprises a safety cover 6 fan rotor of the present invention; the lower surface of this safety cover 6 is provided with the cutting ferrule 7 that can be inserted in annular interpolation slit 5 and match with annular interpolation slit 5 clampings, the upper surface of this safety cover 6 be also provided with that power supply machine output shaft 2 stretches out and with the via hole 8 of motor output shaft 2 close-fittings.In the present embodiment, because being also provided with a guide rod 10 on described motor output shaft lower end motor body 3, therefore the upper surface of safety cover 6 is also provided with a small vias 11 of passing for guide rod 10.
As the improvement project of the present embodiment, between described safety cover 6 and motor output shaft lower end motor body 3, be also provided with a beam 9, certainly on beam 9, be also provided with the hole that power supply machine output shaft 2 and guide rod 10 pass.
As the preferred version of the present embodiment, described safety cover 6 is plastic safety cover, and plastic safety cover is by molding and forming, and cost is low and easy to process, can be mass.
In the present embodiment, also form a plane of inclination 6.1 between the upper surface of described safety cover 6 and bottom, the setting of this plane of inclination 6.1, is easier to throwing away of water.
Claims (3)
1. a fan rotor, comprise housing (1), motor and motor output shaft (2), described motor is loaded in housing (1), the upper surface of described housing (1) is provided with the through hole that power supply machine output shaft (2) stretches out, the edge of this through hole is also provided with protection motor output shaft lower end motor body (3) and guide sleeve (4) protruding upward, between this guide sleeve (4) and motor output shaft lower end motor body (3), form an annular interpolation slit (5), it is characterized in that: it also comprises a safety cover (6), the lower surface of this safety cover (6) is provided with the cutting ferrule (7) that can be inserted in annular interpolation slit (5) and match with annular interpolation slit (5) clamping, the upper surface of this safety cover (6) be also provided with that power supply machine output shaft (2) stretches out and with the via hole (8) of motor output shaft (2) close-fitting.
