Technical field
The utility model relates to a kind of electricity experimental modelling demonstration equipment technical field, relates in particular to a kind of electricity pilot demonstration device.
Background technology
Current classroom teaching, teacher has operated in the plane at dais, all right from the student close to dais, but do not see from the student away from dais when observing or cannot see at all, the aspect of just listening only is rested on from the classmate away from dais, lecture experiment effect is made to become very poor like this, quality of instruction and benefit are greatly affected, teacher can better do not helped to carry out classroom instruction, even teaching task can not be completed in today that instructional blocks of time is more nervous, at some electricity pilot demonstration class, teacher with equipment more, fetch all inconvenient, can only according to circumstances accept or reject, but often sometimes inconsiderate situation, in this case, ongoing electricity pilot demonstration can only be interrupted, cause completing teaching task.And some electro-kinetic instrument volume more greatly or more accurate, in electricity pilot demonstration process, there is the problem of carrying inconvenience.
Summary of the invention
For the defect of above-mentioned prior art, the utility model provides a kind of electricity pilot demonstration device that can conveniently demonstrate, as much as possiblely easily can be with some electricity pilot demonstration equipment, lecture experiment effect is strengthened in giving lessons in classroom, clear, make circuit diagram, connecting circuit, displaying experimentation and content fast.
For achieving the above object, technical solution adopted in the utility model is:
A kind of electricity pilot demonstration device, comprise the Graphic Panel for showing experiment equipment and the support body for supporting Graphic Panel, described electricity pilot demonstration device also comprises a casing, the inner side of the two side of described casing is provided with supporting shaft, described support body, comprises 2 support plates, and described support plate is arranged on the both sides inwall of casing, hinged with supporting shaft, described support plate offers straight trough; One end of described Graphic Panel and the rear wall of casing hinged, the two sides of described Graphic Panel are provided with slideway along the length direction of Graphic Panel, described slideway is provided with the stud along the movement of Graphic Panel length direction, described stud straight trough from the side stretches out, described stud is provided with the set nut for locking Graphic Panel, the back side of described Graphic Panel is provided with magnet, described Graphic Panel is provided with the fixator that several are made up of magnetic metal sheet.
As the improvement to technique scheme, the length of described Graphic Panel equals the length of casing, and the length of described support plate is less than the length of casing.So, after electricity pilot demonstration, can support plate be folded in cabinets cavity, Graphic Panel is put down, can be used as case lid, form a complete electricity pilot demonstration case with casing, can fasten, properly preserve, next time can be taken out and again be tested.
As the improvement to technique scheme, described fixator is iron plate.
As the improvement to technique scheme, described iron plate is galvanized plain sheet, or is the middle iron plate being provided with half-arc groove.
Electricity pilot demonstration device of the present utility model, include casing, the inner chamber of casing can place some more greatly or more accurate demonstration instrument, instant noodles safe to carry, electricity pilot demonstration device is provided with Graphic Panel, is provided with in magnet experimentation the experiment equipment that will carry out directly to be put in panel to show student intuitively after Graphic Panel.
With fixator on Graphic Panel, with the little galvanized plain sheet of several pieces of voluntary activities, drawing is fixed, first can draw circuit diagram on the drawing of Graphic Panel on pretreatment, utilize the principle of galvanized plain sheet and attraction, be convenient to change paper.
To all fix iron plate below the equipment applied in Experiments of Electricity, can directly experimentally need the position by experiment equipment is directly placed in needs according to the requirement of drawn circuit to test when testing.Can with the iron plate fixing cord being with half-arc groove.
Achievable experiment (the generality experiment electricity part can be carried out) has: connect series and parallel connections circuit, exercise uses reometer, probe into the relation of electric current everywhere in series circuit, probe into the relation of main line electric current and each branch current in parallel circuit, exercise uses voltage table, probe into the voltage at electrical appliance two ends in series circuit and the relation of both ends of power voltage, probe into the voltage at parallel circuit each branch road electrical appliance two ends and the relation of both ends of power voltage, probe into the factor affecting conductor resistance size, exercise uses slide rheostat, probe into the relation of electric current and voltage, probe into the relation of electric current and resistance, resistance measurement with voltammetry, measure the electric power etc. of miniature bulb.
Bulb brightness experiment (textbook expansion experiments) when series and parallel connections of comparing different capacity can be demonstrated.
The advantage that the utility model has and good effect are:
Electricity pilot demonstration device of the present utility model, be connected with the adjustable of Graphic Panel by support body, the angle of Graphic Panel can be regulated, student can be made to have better visual angle to watch the electricity test that Graphic Panel does, aged teacher can operate needing some other experiment shown on this experiment demonstrator by experimental needs, electricity test can be shown intuitively on Graphic Panel, directly circuit diagram can be drawn on Graphic Panel, what experiment was become more has logicality, more directly perceived, solves the problem of inconvenient observation of students.Solve distant place student in classroom and cannot watch the problem of experiment.
