Abstract
The utility model relates to a hand press windmill. The hand press windmill comprises a base, wherein both ends of the base are respectively provided with a small bracket and a big bracket; a lever is coupled on the small bracket, and one end of the lever is coupled with a connecting rod; the big bracket is coupled with a windmill blade through a rotation shaft; and the rotation shaft and the connecting rod are connected. According to the hand press windmill, a simple lever principle is adopted, and the small bracket is used as a supporting point to ensure that the windmill blade is ceaselessly rotated, therefore, the structure is simple and creative; due to a U-type crank structure and the lever principle, the lever is slightly lifted and pressed to do up and down reciprocating motions with only one finger, and the motions of the lever can be converted into rotary motions of the windmill blade; and the structure of the hand press windmill is novel, so that the hand press windmill can be used as a toy for training fingers to flexibly and harmoniously move and can also be used as a teaching aid for observing the conversion process of mechanical motion forms for kids to study and search.
Description
Technical field
The utility model relates to a kind of wooden toy, relates in particular to a kind of hand windmill.
Background technology
At present, on market, wooden toy is various, and wooden windmill is rarely found, general windmill is plastics, rotates by wind blows, only under the moving situation of wind, could rotate.
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: a kind of hand windmill; Comprise base, it is characterized in that: the two ends of said 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 said big support is connected with air vane through rotating shaft, and this rotating shaft is connected with connecting rod.
Described hand windmill; It is characterized in that: said big support is made up of two major axis; Said rotating shaft is a U-shaped handle, and these U-shaped handle two ends are coupling respectively on two major axis, and major axis is passed in its end; Wherein an end is connected with said air vane, and the other end is provided with the counterpart that conforms to this air vane quality.
Described hand windmill is characterized in that: said counterpart is a disk.Said small rack is made up of two minor axises, is provided with turning cylinder between two minor axises, and said lever shaft is connected on this turning cylinder.
This hand windmill.Adopting the simple lever principle of letter, is the strong point with the small rack, and lever can move up and down, and drives rotating shaft through connecting rod again and rotates, and air vane is gyrated, simple in structure and have an intention property.Be not only a kind of toy, be used to train the dexterous coordination of finger motion, and a kind of teaching aid, the process that is used to observe the mechanical movement formal transformation.
Through the U-shaped crank structure, and lever principle, whole formation one crank and rocker mechanism.Need only use one to point pressing lever gently; Pump, just can will move up and down converts rotatablely moving of air vane into, 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 supplies child extensively to learn research.Counterpart is used to keep the balance at wind noon, the increase 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 up 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 property.Through the U-shaped crank structure, and lever principle, the individual pressing lever gently of pointing need only be used; Pump, just can the motion of lever be converted into rotatablely moving of air vane, the novel structure of this bar; 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, supply young children research.
Description of drawings
Fig. 1 is the structural representation of the utility model hand windmill;
In the accompanying drawing: 1, base; 2, lever; 3, connecting rod; 4, air vane; 5, rotating shaft; 6, big support; 6-1, major axis; 7, small rack; 7-1, minor axis; 8, turning cylinder; 9, counterpart.
The specific embodiment
That the utility model is made further condition is bright for a knot accompanying drawing below:
A kind of hand windmill; Comprise base 1, it is characterized in that: the two ends of said base 1 are respectively equipped with small rack 7, big support 6, wherein; Be connected with lever 2 on the small rack 7; One end of lever 2 is connected with connecting rod 3, and said big support 6 is connected with air vane 4 through rotating shaft 5, and this rotating shaft 5 is connected with connecting rod 3.Described hand windmill; It is characterized in that: said big support 6 is made up of two major axis 6-1; Said rotating shaft 5 is U-shaped handles, and these U-shaped handle 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 said air vane 4, and the other end is provided with the counterpart 9 that conforms to this air vane 4 quality.Said counterpart 9 is disks.Said small rack 7 is made up of two minor axis 7-1, is provided with turning cylinder 8 between the two minor axis 7-1, and said lever 2 is coupling on this turning cylinder 8.Connecting rod 3 is connected the middle part of U-shaped crank.Through the U-shaped crank structure, and lever principle, need only use one to point pressure-lift lever 2 gently, do the up-downgoing reciprocating cutter, convert rotatablely moving of air vane 4 into.Such novel structure can be used to train the dexterous coordination of finger motion, and the exposed outside of this structure, and the process that can observe the mechanical movement formal transformation supplies young children research.
