Abstract
The utility model relates to a circuit teaching demonstration board, belonging to the technical field of a physics teaching aid. The circuit demonstrator adopts the following technical scheme that: the circuit teaching demonstration board comprises a board body and a mounting hole, and is characterized in that a rotating shaft is arranged at the upper end of the board body, a support arm is arranged on the rotating shaft, a hinge is arranged on the support arm, a supporting board is arranged on the hinge, and a rubber strip is arranged at the lower end of the board body. The circuit teaching demonstration board has simple structure, ensures that the students can have a clearer understanding in the physics circuit experiment teaching, and reduces the workload of the teacher.
Description
Technical field: the utility model belongs to physics teaching apparatus technical field, is a kind of circuit demonstrator specifically.
Background technology: at present, be that element is inserted on the demonstrator mostly in the physical circuit teaching Process of experiment, connect with power lead again, this demonstrator is merely able to install the back teaching, can not see by the limit rim, can not give the student one and be familiar with more clearly, increased work difficulty to the teacher.
Summary of the invention: the purpose of this utility model provides a kind of circuit demonstrator that can give a more clear understanding of student when the physical circuit experimental teaching.
The technical solution of the utility model is: comprise plate body and mounting hole, it is characterized in that being provided with rotating shaft in the plate body upper end that rotating shaft is provided with support arm, support arm is provided with folding, and folding is provided with supporting plate, and the plate body lower end is provided with rubber strip.
The beneficial effects of the utility model are: the utility model is simple in structure, can give more clear understanding of student when the physical circuit experimental teaching, has alleviated teacher's work difficulty.
Description of drawings: accompanying drawing 1 is a structural representation of the present utility model.
Among the figure 1, plate body, 2, mounting hole, 3, rotating shaft, 4, support arm, 5, folding, 6, supporting plate, 7, rubber strip.
Embodiment: comprise plate body 1 and mounting hole 2, it is characterized in that being provided with rotating shaft 3 in plate body 1 upper end that rotating shaft 3 is provided with support arm 4, support arm 4 is provided with folding 5, and folding 5 is provided with supporting plate 6, and plate body 1 lower end is provided with rubber strip 7.When the physical circuit experimental teaching, erect plate body 1,7 of rubber strips increase friction force on the table, launch folding 5, and 6 of supporting plates are got final product on the table.
