Description
Technical field
The utility model relates to a kind of demonstrator, particularly a kind of functional image demonstrator.
Background technology
In Function Teaching work, teacher generally needs to draw plane right-angle coordinate in the side of blackboard, and then draw required functional image in this coordinate system, often repeatedly wipe, repeatedly draw, so just cause coordinate system incompleteness fuzzy, students just cannot analyze the Changing Pattern in functional image more clearly, and also have the angle of the position residing for some students and drawn image excessive, very likely cause situation about can not better observe, SIN function and cosine function are the important function in trigonometric function simultaneously, its figure is waveform, therebetween can mutually change, simple harmonic oscillation is exactly the simplest mechanical oscillation of one, and can be showed more intuitively by functional image demonstrator.
Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, thering is provided a kind of can make student see relation between simple harmonic oscillation and sin cos functions very intuitively, and facilitate the student of different angles to observe, and simultaneously detachable, be convenient to the functional image demonstrator that teacher carries.
To achieve these goals, the technical solution adopted in the utility model is such: functional image demonstrator of the present utility model, comprise two support columns and base, two support columns are equipped with source of parallel light, one support column is connected with base, another support column is unsettled, connected by support frame between two support columns, and unsettled support column is positioned at support frame frame, and the support column be connected with base is provided with direct current generator, direct current generator is provided with reductor, direct current generator is electrically connected with reductor, reductor is vertically provided with a rotating shaft, a level is installed and transparent swing arm in this rotating shaft upper end, the outboard end of this swing arm installs a black ball, and black ball and setting source of parallel light is on the support columns the level of state, a magnet button is connected outside supporting frame, magnet buckles connection one magnet base, magnet base is divided into interior base and outer base, interior base connects a magnetic vertical rod, magnetic vertical rod is connected with interior base one, magnetic vertical rod is crossed a bearing, bearing is connected with rotating shaft, rotating shaft parallels with magnetic vertical rod, and be rotationally connected with bearing.
Further, as a kind of concrete version, rotating shaft upper end described in the utility model is provided with a horizontal through hole, and the medial end of setting-in swing arm in through hole forms a plane inside swing arm, plane crimps a jackscrew.
Further, as a kind of concrete version, rotating shaft described in the utility model is connected with reductor by pivot pin.
Compared with prior art, the utility model has the advantage of: this functional image demonstrator can make student see relation between simple harmonic oscillation and sin cos functions very intuitively, and facilitate the student of different angles to observe, and simultaneously detachable, be convenient to teacher and carry.
