Abstract
A novel special hand generator for students relates to a hand generator. A first gear, a second gear, a third gear, a fourth gear and a motor gear are arranged inside a power generating cabinet, wherein each of the first gear, the second gear, the third gear and the fourth gear is formed by a gear wheel and a pinion respectively; the gear wheel of the first gear is engaged with the pinion of the second gear; the gear wheel of the second gear is engaged with the pinion of the third gear; the gear wheel of the third gear is engaged with the pinion of the fourth gear; the gear wheel of the fourth gear is engaged with the motor gear; a handle is connected with the pinion of the first gear through a connecting shaft; the generator is fixedly connected on one side of the power generating cabinet; the generator is connected with the motor gear; and the handle is rotated, and through mutual driving of the handle and the first gear, force generated by an acceleration drives the generator to rotate and generate electricity. The novel special hand generator for the students is simple in structure and easy to assemble.
Description
Technical field:
The utility model relates to a kind of hand generator, is specifically related to the special-purpose hand generator of a kind of novel student.
Background technique:
Student's learning interest and the practical ability of cultivating the student are more and more paid attention in present education, but the structure of some experiment equipments in school laboratory is more complicated all, profile such as hand generator is very large and very heavy, internal gear is a lot, structure is very complicated, the student can not assemble the complicated structure in the inside, does not reach the practical ability of cultivating the student, has reduced the interest of Students ' Learning.
The model utility content:
The purpose of this utility model provides the special-purpose hand generator of a kind of novel student, its cost is lower, profile is moderate, simple in structure, easily assembling, student's disassemble or assemble are very simple, strengthen the practical ability of cultivating the student, excite their more learning interest, make study, studied into a happy thing.Reach and cultivate the purpose that Students ' Learning physics practice and theory combines.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises hand cranking handle 1, generating casing 2 and generator 3; 2 li of casings of generating are provided with the first gear 2-1, the second gear 2-2, the 3rd gear 2-3, the 4th gear 2-4 and motor gear 2-5, the first gear 2-1, the second gear 2-2, the 3rd gear 2-3, the 4th gear 2-4 is formed by small one and large one two Gear combination, the pinion of the gearwheel of the first gear 2-1 and the second gear 2-2, the pinion of the gearwheel of the second gear 2-2 and the 3rd gear 2-3, the pinion of the gearwheel of the 3rd gear 2-3 and the 4th gear 2-4, the gearwheel of the 4th gear 2-4 and motor gear 2-5 engagement, hand cranking handle 1 is connected with the little tooth of the first gear 2-1 by coupling shaft 4, generator 3 is fixedly connected on a side of generating casing 2, and generator 3 links to each other with motor gear 2-5.
Rotate hand cranking handle 1, the first gear 2-1 drives the second gear 2-2, and the second gear 2-2 drives the 3rd gear 2-3, and the 3rd gear 2-3 drives the 4th gear 2-4, the 4th gear 2-4 drive motor gear 2-5 rotates, and the power that acceleration produces drives generator 3 running generation currents.
The utility model cost is lower, and profile is moderate, and is simple in structure, easily assembling, and student's disassemble or assemble are very simple, strengthened student's practical ability, excite their more learning interest.
