Abstract
The utility model relates to a generator model belonging to the technical field of teaching demonstration tool. The generator model is used for solving problems of complicated structure and high manufacturing cost of a prior generator model. According to the utility model, a rotary shaft is connected with a rotary shaft support through two bearing bases. The rotary shaft is connected with a bottom board. The rotary shaft is connected with a coil through a coil rack. Steel magnets on two sides of the coil are installed on the bottom board through steel magnet supports. Two ends of the coil are connected with two slide rings respectively. The two slide rings are connected with two electric brushes respectively. The two electric brushes are connected with an electric brush support through an insulating rod. The electric brush support is connected with the bottom board. A lamp support is connected with the bottom board. Electric brushes are connected with connection leads. The two connection leads are connected with a positive electrode and a negative electrode of a light emitting diode on the lamp support. A large belt wheel is connected with the bottom board through a belt wheel support. A handle is installed on the large belt wheel. The large belt wheel is connected with a small belt wheel through a transmission belt. The small belt wheel is connected with the rotary shaft. The generator model can be widely applied to teaching demonstration.
Description
Technical field
The utility model relates to a kind of teaching demonstration apparatus, particularly a kind of generator model.
Background technology
The existing generator model that is used for enlightenment teaching all is to adopt common bulb to represent the effect of generating electricity.Because the common bulb power consumption is big, coil need be carried out the high speed rotation between the magnet of the two poles of the earth, just can make common bulb light, therefore the gear mechanism of multi-stage acceleration need be set.There is the high deficiency of complex structure and cost.
Summary of the invention
The utility model overcomes deficiency of the prior art, and the generator model at the bottom of a kind of simple in structure and cost is provided.
In order to solve above-mentioned technical matters, the utility model is achieved through the following technical solutions: the structure of generator model, comprise that rotation axis passes through two bearing seats and is connected with the rotating shaft frame, the rotating shaft frame is connected with base plate, rotation axis is connected with coil by coil former, the magnet steel of coil both sides is contained on the base plate by the magnet steel frame, the two ends of coil are connected with two slip rings respectively, two slip rings are connected with two brushes respectively, two brushes are connected with brush carriage by insulating bar, and brush carriage is connected with base plate, and lamp bracket is connected with base plate, brush be connected lead and connect, especially two connect on lead and the lamp bracket light emitting diode just, negative pole connects, and big belt pulley is connected with base plate by pulley support, and handle is housed on the big belt pulley, big belt pulley is connected with small belt pulley by driving belt, and small belt pulley is connected with rotation axis.
Compared with prior art, the beneficial effects of the utility model are: at the bottom of the simple in structure and cost of generator model, be convenient to make, popularize.
