Description
technical field:
The utility model relates to political economy equipment and facilities, is specifically related to a kind of circle drawing plate for political economy teaching.
background technology:
To on university student during political economy course, teacher needs with the coherent element that drawing with coloured chalk circle represents in political economy course on blackboard, and the corresponding relation of asking of large millet difference coherent element that order needs are justified.Traditional picture circle method, except completely with sensation picture, cause figure inaccurate outside, also have teacher to draw circle with general plectane of drawing, but due to the special media of blackboard, often traditional picture plectane is difficult to fixing, easily skids, not only troublesome poeration, and be not easy alignment, affect teaching efficiency, in order to solve the problems of the technologies described above, a kind of new technical scheme of special proposition.
utility model content:
The purpose of this utility model is the weak point existed to overcome above-mentioned prior art, and provides a kind of circle drawing plate for political economy teaching, and it is easy to use, simple to operate, be easy to large-scale promotion application.
The technical solution adopted in the utility model is: a kind of circle drawing plate for political economy teaching, comprise track, rule, base, handgrip and move block, base is the square of hollow, base upper surface is provided with handgrip, chassis interior is provided with track, track is connected with slide block, slide block is connected with push rod, push rod one end with move block and be connected, move block and be provided with pointer, pointer refers on the scale and rule is positioned on base upper surface, the push rod other end is connected with slideway, slideway is connected with sliding shoe, sliding shoe is connected with half smooth block, half smooth block inside is provided with fixed block, fixed block is connected with spring rail, spring rail overcoat has spring, spring is connected with half smooth block, base is provided with annulus.
Described slideway is the fan-shaped of hollow, and the quantity of slideway is four.
The quantity of described handgrip is four.
The quantity of half described smooth block is eight.
The beneficial effects of the utility model are: in the process used, by moving block, make finger slips to rule assigned scale, move block simultaneously and promote push rod, push rod promotes slideway, half smooth block is tightened up, simultaneously by the effect of spring, two and half smooth blocks are tightened up simultaneously, the circle that after tightening up, formation one is whole, teacher can carry out picture circle wherein, and this apparatus structure is simple, to easy and simple to handle during political economy course on university student, easily align, improve teaching efficiency.
accompanying drawing illustrates:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model partial enlarged drawing.
detailed description of the invention:
With reference to accompanying drawing, a kind of circle drawing plate for political economy teaching, comprise track 1, rule 2, base 3, handgrip 4 and move block 5, base 3 is the square of hollow, base 3 upper surface is provided with handgrip 4, base 3 inside is provided with track 1, track 1 is connected with slide block 12, slide block 12 is connected with push rod 13, push rod 13 one end with move block 5 and be connected, move block 5 and be provided with pointer 6, pointer 6 refers on rule 2 and rule 2 is positioned on base 3 upper surface, push rod 13 other end is connected with slideway 11, slideway 11 is connected with sliding shoe 10, sliding shoe 10 is connected with half smooth block 8, half smooth block 8 inside is provided with fixed block 9, fixed block 9 is connected with spring rail 15, spring rail 15 overcoat has spring 14, spring 14 is connected with half smooth block 8, base 3 is provided with annulus 7.Described slideway 11 is the fan-shaped of hollow, and the quantity of slideway 11 is four.The quantity of described handgrip 4 is four.The quantity of half described smooth block 8 is eight.In the process used, by moving block 5, pointer 6 is made to slide into rule 2 assigned scale, move block 5 simultaneously and promote push rod 13, push rod 13 promotes slideway 11, and half smooth block 8 is tightened up, simultaneously by the effect of spring 14, two and half smooth blocks 8 are tightened up simultaneously, the circle that after tightening up, formation one is whole, teacher can carry out picture circle wherein, and this apparatus structure is simple, to easy and simple to handle during political economy course on university student, easily align, improve teaching efficiency.
