Abstract
A hand-pressed windmill comprises a base, wherein a small bracket and a big bracket are arranged at two ends of the base respectively; a lever is coupled to the small bracket, and a connecting rod is coupled to one end of the lever; and air wings are coupled to the big bracket via a rotating shaft connected with the connecting rod. Based on the simple lever principle, the utility model takes the small bracket as the supporting point, so that the air wings can rotate ceaselessly, resulting in simple structure and originality. By virtue of the U-shaped crank structure and the lever principle, all that needed is to press and lift the lever in a reciprocating manner only by one finger, so as to transform the motion of the lever to the rotating motion of the air wings. The novel structure can serve not only as a toy to train the finger to be dexterous and harmonious in motion but also as a teaching aid to observe the process of formal transformation of the mechanical motion, so as to be studied by children.
Description
Technical field
The utility model relates to a kind of wooden toy, relates in particular to a kind of hand windmill.
Background technology
In the market, wooden toy is various, and wooden windmill is rarely found, general windmill is plastics, rotates by wind blows, only could rotate under the moving situation of wind.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of wooden hand windmill is provided, and is used to train finger motion, and the process of observing the mechanical movement formal transformation.
The utility model solves the technical scheme that its technical problem adopts: this hand windmill, comprise base, the two ends of this base are respectively equipped with small rack, big support, wherein, be connected with lever on the small rack, one end of lever is connected with connecting rod, and big support is connected with air vane by rotating shaft, and this rotating shaft is connected with connecting rod.Adopting simple lever principle, is the strong point with the small rack, and lever can move up and down, and drives rotating shaft by connecting rod again and rotates, and air vane is gyrated, simple in structure and have an intention.Be not only a kind of toy, be used to train the dexterous coordination of finger motion, and be a kind of teaching aid, be used to observe the process of mechanical movement formal transformation.
Big support is made of two major axis, and rotating shaft is a U-shaped crank, and these U-shaped crank two ends are coupling respectively on two major axis, and its end passes major axis, and wherein an end is connected with described air vane, and the other end is provided with the counterpart that conforms to this air vane quality.By the U-shaped crank structure, and lever principle, whole formation one crank and rocker mechanism.Need only point pressing lever gently with one, pump, just can will move up and down and be converted to rotatablely moving of air vane, such novel structure, can train the dexterous coordination of finger motion, and the exposed outside of this structure, the process that can observe the mechanical movement formal transformation is for young children research.Counterpart is used to keep the balance of windmill, increases rotary inertia.
Counterpart is a disk, and this disk not only improves the balance of windmill, and increases rotary inertia, makes windmill be more prone to rotate, and increases attractive in appearance that windmill rotates.
Small rack is made of two minor axises, is provided with turning cylinder between two minor axises, and wherein lever shaft is connected on this turning cylinder, adopts turning cylinder can increase the flexibility that lever rotates.
The effect that the utility model is useful is: the utility model adopts simple lever principle, is the strong point with the small rack, and air vane is gyrated, and is simple in structure and have intention.By the U-shaped crank structure, and lever principle, need only point pressing lever gently with one, pump, just the motion of lever can be converted to rotatablely moving of air vane, such novel structure, be not only a kind of toy, be used to train the dexterous coordination of finger motion, and be a kind of teaching aid, be used to observe the process of mechanical movement formal transformation, for young children research.

Description of reference numerals: base plate 1, lever 2, connecting rod 3, air vane 4, rotating shaft 5, big support 6, major axis 6-1, small rack 7, minor axis 7-1, turning cylinder 8, counterpart 9.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
With reference to accompanying drawing: this hand windmill, comprise base 1, the two ends of this base 1 are respectively equipped with small rack 7, big support 6, and wherein, big support 6 is made of two major axis 6-1, and small rack 6 is made of two minor axis 7-1, is provided with turning cylinder 8 between the two minor axis 7-1.Lever 2 is coupling on this turning cylinder 8, and the other end of lever 2 is connected with connecting rod 3.Big support 7 is connected with air vane 4 by rotating shaft 5, rotating shaft 5 is U-shaped cranks, these U-shaped crank two ends are coupling respectively on two major axis 6-1, and major axis 6-1 is passed in its end, wherein an end is connected with described air vane 4, the other end is provided with the counterpart 9 that conforms to this air vane 4 quality, and this counterpart 9 is disks 9.Connecting rod 3 is connected the middle part of U-shaped crank.By the U-shaped crank structure, with lever principle, need only point pressing lever 2 gently with one, pump, be converted to rotatablely moving of air vane 4.Such novel structure can be trained the dexterous coordination of finger motion, and the exposed outside of this structure, and the process that can observe the mechanical movement formal transformation is for young children research.
Though the utility model illustrates and describes by the reference preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
