Abstract
The utility model discloses a fan which adopts a mechanical lever and a gear wheel as the transmission. A motor connects and drives a plurality of speed reduction wheels and working gear wheels. A connecting rod on the working gear wheel is glidingly connected with a sliding slot on one end of the working lever. The working lever drives a spring to pull a plate. The spring drags the working rod and a sector surface to move. The utility model can imitate the motion of the hand-operated fan, and the utility model blows the natural and soft wind. The utility model can be also used for the toys and the flying instruments or the water propelling devices.
Description
The utility model relates to a kind of fan of doing transmission with mechanical lever and gear.
At present, the mechanical electric fan of use, flabellum are that rotation is dried, and this wind is felt under the weather the people, lacks the impression of hand fan.
The purpose of this utility model is to provide a kind of can simulate the mechanical fan of hand fan, improves the defective that existing electric fan wind is strong, wind is hard.
Task of the present utility model is finished as follows: motor connects the some ratio wheels of drive, and ratio wheel connects working gear; Link rod on the working gear and working lever one end are slidingly connected, the other end of working lever is slidingly connected with the spring arm-tie again, the working beam middle part connects with spring, and the working beam other end connects covering of the fan, connects working lever, spring arm-tie, working beam with three hinge axis respectively on the supporting plate.There are two chutes at the working lever two ends, and working gear also connects with hinge axis with link rod.
The utility model is also further specifically finished as follows: the chute at working lever two ends is connected by the pin slide on spring arm-tie and the link rod respectively.Limit spring one end connects limiting plate, and limiting plate one end connects working beam by bearing pin.Two spring arm-ties are fixed on the supporting plate of both sides, and working beam is between spring arm-tie, chute.
The mechanism's fan that uses the utility model to provide can imitate the wind that hand fan motion and hand fan blow out, and soft naturally, this device also can be used for toy aircraft tool or water propeller simultaneously.
Below in conjunction with accompanying drawing the utility model is done further narration.
Fig. 1 is the structural representation of original state of the present utility model.
Fig. 2 is the structural representation of duty of the present utility model.
With reference to Fig. 1, be fixed in the rotating shaft 1 on the supporting plate (not drawing among the figure) working gear is arranged, working gear connects with link rod 16 usefulness hinge axis 19, the bearing pin 2 of link rod 16 other ends is slidingly connected the chute 17 of working beam thick stick 4, working lever 4 middle parts have a hinge axis 3 also to be fixed on the supporting plate, the chute 6 of the working lever other end connects with spring arm-tie 9 by the bearing pin 18 on the spring arm-tie, spring arm-tie other end hinge axis 10 connecting rack plates, spring 7 one ends connect with the working beam middle part, one end connects with spring arm-tie 9 one ends, working beam 14 1 ends are connected on the supporting plate by bearing pin 15, and the middle part also has a limiting plate 13, limit spring 12 1 end connecting link pins 11, the other end connects limiting plate 13, limiting plate 13 other ends connect working beam 14 again, and working beam is positioned at two limit spring 12, limiting plate 13, between the spring arm-tie 9, two stabilizing rings 8 are positioned at the working beam both sides, rise and stablize, the effect of rocking of restraint of labour bar.
With reference to Fig. 2, when working gear 5 rotated 180 °, link rod 16 descended, and drove working lever and lifted around hinge axis 3 rotations.Spring arm-tie 9 is rotated by force by bearing pin 18 and dead slot 6 and spurs working spring 7, working spring 7 spurs working beam 14 again suddenly, then the covering of the fan on the working beam 14 is instigated once, when working gear rotates 180 ° when getting back to initial position again, then working lever 4, covering of the fan spring arm-tie 9, working beam 14 is got back to initial position.Week and rejuvenate according to this repeatedly, has reached the effect and the purpose of mechanical fan like this.
Claims (4)
1, a kind of mechanical fan that can imitate hand fan, by covering of the fan, motor, swing, transmission and release energy machine spare are formed, it is characterized in that connecting the some ratio wheels of drive by motor, ratio wheel connects working gear 5, link rod 16 on the working gear 5 is slidingly connected with working lever 4 one ends, the other end of working lever 4 again with spring arm-tie 9 on bearing pin 18 be slidingly connected, working beam 14 middle parts connect with spring arm-tie 9 usefulness springs 7, working beam 14 1 ends connect covering of the fan, use hinge axis 10 on the supporting plate respectively, 15,3 connect working beam 14, spring arm-tie 9, working beam 14, there are chute 6 and 17 in working lever 4 two ends, and working gear 5 also connects with hinge axis 19 with link rod 16.
2, according to the described mechanical fan of claim 1, the chute 6,17 that it is characterized in that working lever 4 two ends is connected by spring arm-tie and the pin slide that connects on 16 respectively.
3, according to the described mechanical fan of claim 1, it is characterized in that limit spring 12 1 ends connect limiting plate 13, limiting plate 13 1 ends connect working beam 14 by bearing pin.
4, according to the described mechanical fan of claim 1, it is characterized in that two spring arm-ties 9 are fixed on the supporting plate of both sides, working beam 14 is between spring arm-tie 9, chute 6.
