Description
Technical field
The utility model belongs to mathematics teacher apparatus technical field, refers in particular to a kind of mathematics teacher and uses para-curve analogue means.
Background technology
ZL87208597.X discloses a kind of Parabola test table based on magnetic principle, which overcome the defect of traditional parabolic ball experimental method, namely, make a mark according to the relevant position of each steel ball on planimetric rectangular coordinates, then each mark is coupled together, mark is held in the motion of drawing out object, and this experimental method need can obtain the relevant position of steel ball through test of many times, its formality is numerous and diverse, and error is very large.
Still there are the coloured pen core of mounting strap, pen core on paraboloid can be plotted on corresponding paper by its movement locus by object of which movement rule in addition, sometimes because of pen core loose contact, and its movement locus can not be drawn.These technology all can not adjust angle when parabolic ball is dished out, and make troubles to teaching.
Summary of the invention
The purpose of this utility model is to provide a kind of safe and reliable, and the better mathematics teacher of practicality uses para-curve analogue means.
For achieving the above object, the utility model provides following technical scheme:
A kind of mathematics teacher uses para-curve analogue means, comprise framework and parabolic ball, the middle part of framework is provided with magnetic force central layer, described magnetic force central layer comprises front panel, rear panel and is arranged on several the cellular display units between two panels, and the inner chamber of each display unit is all full of magnetic dispersion soln; The side of described framework upper is provided with acceleration orbit, and the inner of acceleration orbit is arranged on framework by rotating shaft; The pilot hole of several angular setting of dishing out for parabolic ball is furnished with on described framework, centered by rotating shaft; Track is provided with the pin-and-hole coordinated with described pilot hole, in pin-and-hole, is provided with register pin; Described front panel is transparent plastic plate.
The bottom of described framework is provided with base plate, and the upper side of base plate is connected by corner block with the leading flank of framework.
Described parabolic ball is magnetic ball.
The utility model beneficial effect is compared to existing technology:
Structure of the present utility model is simple, and safe and reliable, can adjust the injection angle of parabolic ball very easily, practicality is good.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of mathematics teacher uses para-curve analogue means, comprise framework 6 and parabolic ball 1, the middle part of framework 6 is provided with magnetic force central layer 7, described magnetic force central layer 7 comprises front panel, rear panel and is arranged on several the cellular display units between two panels, and the inner chamber of each display unit is all full of magnetic dispersion soln; The side on described framework 6 top is provided with acceleration orbit 3, and the inner of acceleration orbit 3 is arranged on framework 6 by rotating shaft 2; The pilot hole 5 of several angular setting of dishing out for parabolic ball is furnished with on described framework 6, centered by rotating shaft 2; Track 3 is provided with the pin-and-hole coordinated with described pilot hole, in pin-and-hole, is provided with register pin 4; Described front panel is transparent plastic plate.
The bottom of described framework 6 is provided with base plate 8, and the upper side of base plate 8 is connected by corner block 9 with the leading flank of framework 6.
Described parabolic ball is magnetic ball.
The utility model can improve student puts down its motion when throwing and object are tiltedly thrown to object and holds the visual understanding of mark, to strengthen understanding, and can replace manual demonstration.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
