Description
Technical field
This utility model relates to a kind of teaching aid, especially a kind of College Maths planar graph demonstration teaching aid.
Background technology
At present, in the teaching of abovementioned mathematical plane figure, it is the most all by teacher's Freehandhand-drawing planar graph on blackboard, or directly
Connect allow student make reference to the text-book on planar graph explain.This teaching method very abstract, needs student to have good
Good understandability and imaginative power, student is typically only capable to temporary reception and understanding and is hardly formed impression intuitively, simultaneously
Return teachers' instruction and add burden, and waste time in classroom.Additionally, teacher is when some irregular figures of Freehandhand-drawing,
It is difficult to hold the accuracy of figure, easily makes student that the understanding of figure is produced deviation.
Summary of the invention
The purpose of this utility model is to provide a kind of College Maths planar graph demonstration teaching aid, and it can be drilled the most accurately
Show College Maths planar graph.
Realizing above-mentioned purpose, this utility model takes following technical proposals:
A kind of College Maths planar graph demonstration teaching aid, including base plate, graph paper, clipboard, two pieces of baffle plates, polylith demonstrations
Plate, multiple cylinder, polylith lamella lucida and multiple slot tag, two pieces of described baffle plates are vertically set up in parallel, under two pieces of baffle plates
End face is each attached on base plate, is provided with polylith demonstration board between two pieces of baffle plates, and described polylith demonstration board is vertically set up in parallel, often
The each tailpiece of the piston rod with a cylinder in the centre position of the lower surface of block demonstration board is rotationally connected, the cylinder body of each described cylinder
End is each attached on base plate, two outer side elevations of every piece of demonstration board is equipped with groove, on two outer side elevations of every piece of demonstration board
Groove one end all hinged with one end of one piece of corresponding lamella lucida, the both sides of the upper surface of every piece of demonstration board are each provided with one
Slot tag, described graph paper is provided with coordinate net ruling, and graph paper is laid in a groove of any one piece of demonstration board,
On the outer side elevation of one of baffle plate that described clipboard is fixed on two pieces of baffle plates.
Compared with prior art, the beneficial effects of the utility model are: this utility model is provided with polylith demonstration board, demonstration board
It is equipped with cylinder, simple to operate, and the rotatable beneficially contrast teaching of demonstration board；It is additionally arranged the graph paper with coordinate net ruling
And lamella lucida, teacher can utilize the coordinate net ruling on graph paper as with reference to accurately drawing in lamella lucida；Teacher is permissible
In the time after school, required figure is first drawn out, it is to avoid waste time in classroom；Additionally, this utility model there is also mounted locking
Castor, is moved easily.
Accompanying drawing explanation
Fig. 1 is the overall structure axonometric drawing of College Maths planar graph demonstration teaching aid of the present utility model.
Fig. 2 is the top view of the demonstration teaching aid shown in Fig. 1；
Component names shown in figure and label are as follows:
1-base plate；2-baffle plate；3-demonstration board；4-cylinder；5-graph paper；6-lamella lucida；7-clipboard；8-locks castor；
9-slot tag.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model is carried out clear,
It is fully described by, it is clear that described embodiment is only a part of embodiment of utility model rather than whole embodiments,
Based on the embodiment in this utility model, those of ordinary skill in the art are obtained under not making creative work premise
Every other embodiment, broadly falls into the scope of this utility model protection.
As shown in Fig. 1 ~ Fig. 2, the utility model discloses a kind of College Maths planar graph demonstration teaching aid, including base plate 1,
Graph paper 5,7, two pieces of baffle plates 2 of clipboard, polylith demonstration board 3, multiple cylinder 4, polylith lamella lucida 6 and multiple slot tag 9, institute
The two pieces of baffle plates 2 stated vertically are set up in parallel, and the lower surface of two pieces of baffle plates 2 is each attached on base plate 1, are provided with between two pieces of baffle plates 2
Polylith demonstration board 3, described polylith demonstration board 3 is vertically set up in parallel, and the centre position of the lower surface of every piece of demonstration board 3 is each with one
