Description
Technical field
The utility model relates to a kind of instructional device, particularly a kind of new teaching demonstration device.
Background technology
In the Teaching in University process, the teacher uses demo rack through regular meeting in teaching process, and ready courseware card directly is used for teaching demonstration by demo rack.Perhaps adopt the multimedia overhead projector technology, with the courseware of making in advance, by the projection demonstration, but the demo rack profile clumsiness of using at present is of rude workmanship, and it is big to take up room, arbitrarily lifting of height, and the anglec of rotation arbitrarily.Particularly, under the bad situation of light, the demonstration effect just more will be had a greatly reduced quality.The student viewing that this is unfavorable for diverse location influences teaching efficiency.And the multimedia overhead projector technology, its equipment investment cost height, and complicated operation, maintenance cost is also quite high in the later stage use, nor can realize multi angle view.
Summary of the invention
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of new teaching demonstration device is provided, and reasonable in design is simply light, conveniently moving.
Its technical scheme is: comprise base, support bar, swivel joint, demonstration board, protective cover, electronic whiteboard, magnet board, on the base that support bar is fixed, the top of described support bar connects demonstration board by swivel joint, the top fixed blade guard of demonstration board, fixedly electronic whiteboard and magnet board on the described demonstration board, described magnet board is provided with magnet.
Above-mentioned support bar is provided with expansion joint, and expansion joint is provided with fastening bolt.
The beneficial effects of the utility model are: simple in structure, easy to use, it is arbitrarily angled that swivel joint can realize that demonstration board rotates to, the student of each position can both well be watched, reasonable in design, simply light, conveniently moving, so both improve the quality of teachers ' teaching, helped improving student's learning efficiency.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Among the last figure: base 1, support bar 2, swivel joint 3, demonstration board 4, protective cover 5, electronic whiteboard 6, magnet board 7, expansion joint 8, fastening bolt 9, magnet 10.
The specific embodiment
In conjunction with the accompanying drawings 1, the utility model will be further described:
The utility model comprises base 1, support bar 2, swivel joint 3, demonstration board 4, protective cover 5, electronic whiteboard 6, magnet board 7, on the base 1 that support bar 2 is fixed, the top of described support bar 2 connects demonstration board 4 by swivel joint 3, the top fixed blade guard 5 of demonstration board 4, fixedly electronic whiteboard 6 and magnet board 7 on the described demonstration board 4, described magnet board 7 is provided with magnet 10, and described support bar 2 is provided with expansion joint 8, and expansion joint 8 is provided with fastening bolt 9.
Of the present utility model simple in structure, easy to use, it is arbitrarily angled that swivel joint can realize that demonstration board rotates to, the student of each position can both well be watched, reasonable in design, simply light, conveniently moving, so both improve the quality of teachers ' teaching, helped improving student's learning efficiency.
