The mathematic demonstration operating platform comprises a tabletop plate which is used for placing demonstration appliances, supporting rods and a base. The mathematic demonstration operating platform is characterized in that the supporting rods are arranged below the tabletop plate, the lower ends of the supporting rods are fixedly arranged on the base through universal wheels, a motor and a control cabinet are arranged on the base, and the motor and the control cabinet are connected with tabletop plate control keys through electric wires; and 2-4 retractable auxiliary supporting rods are fixedly arranged at the bottom of the tabletop plate, rotating wheels are arranged at the upper ends of the supporting rods and the lower ends of the supporting rods are connected with the universal wheels. The mathematic demonstration operating platform has the beneficial effects that the structure is simple, the design is reasonable, the demonstration can be conducted at different angles and heights, not only can the observation and the learning of students be facilitated, but also the teaching burdens of teachers can be reduced, and the teaching efficiency can be improved.
Description
Technical field
The utility model belongs to the teaching aid technical field, relates in particular to a kind of maths demonstration operating desk.
Background technology
At present, when math teacher needs the doing mathematics experimental demonstration on the dais, generally on lectern, carry out; Because the student is distributed in each different orientation in classroom, and demonstration only can be towards a certain direction, so; Be difficult to guarantee that each student can both clearly see whole presentation process clearly, in order to let the student see presentation process clearly as far as possible, teacher has to let students be trapped among observation around the dais; Sometimes also need constantly to change the angle and direction of demonstration, so not only influence teaching efficiency, increased teacher's teaching load; And reduced efficiency of teaching, influenced the Students'learning effect.
Summary of the invention
It is a kind of simple in structure, reasonable in design that the purpose of the utility model is to provide, can a plurality of angles and highly demonstrate, and not only make things convenient for observation of students study, and alleviate teacher's teaching load, can improve the maths demonstration operating desk of efficiency of teaching.
In order to reach above purpose; The technical scheme that the utility model adopted is: the maths demonstration operating desk; Comprise the desktop, support bar and the support that are used to place demonstration equipment, it is characterized in that: said desktop below is provided with support bar, and the support bar lower end is fixed on the support through universal wheel; Support is provided with motor and switch board, and said motor is connected with the desktop operating key through electric wire with switch board.
The bottom of said desktop is fixed with 2-4 telescopic auxiliary support bar, and the upper end of said support bar is provided with moving runner, and the lower end connects universal wheel.
The middle part base plate face of said desktop is provided with and the suitable rotation slot of said moving runner, and the moving runner of post upper places in the rotation slot of desktop.
Said desktop front is provided with operating key, easily realizes the rotation of desktop.
The beneficial effect of the utility model is: simple in structure, reasonable in design, can be in all angles and highly demonstrate, and not only make things convenient for observation of students study, and alleviated teacher's teaching load, can improve efficiency of teaching.
