Description
Technical field
The utility model relates to economic technology field, specifically a kind of Teaching of Economics drawing rule.
Background technology
Economics is a modern independent educational project, is the subject about law of economic development.When Economics Courses is imparted knowledge to students, corresponding relation between teacher needs to explain to ratio with drawing with coloured chalk pie chart on blackboard, the method for traditional painted cake figure, completely with sensation picture, cause that the figure of picture is not accurate enough, standard, had a strong impact on student to the interest of teachers' instruction content and the degree of understanding; Also have teachers association to draw circle with general plectane of drawing, traditional picture plectane is difficult to fixing, easily skids, not only troublesome poeration, and is not easy alignment and affects teaching efficiency; And picture mode is single, the requirement of various graphic plotting in Economics Courses teaching process can not be met.
Utility model content
The purpose of this utility model is to provide a kind of Teaching of Economics drawing rule, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of Teaching of Economics drawing rule, comprise I shape magnet, secondary chi, main scale and picture sliding shoe, described main scale is provided with chute, movable block and secondary chi is embedded with in chute, by column spinner auxiliary connection chi on movable block, main scale both sides and secondary chi are equipped with graduation mark, slide respectively and be provided with a picture sliding shoe in main scale both sides, picture sliding shoe end is provided with picture pen, main scale one end is provided with storage U disk, the main scale other end is provided with hollow disk, hollow disk inside is inlaid with I shape magnet, I shape magnet upper surface is provided with dial, hollow disk is provided with the positioning pointer towards dial.
As further program of the utility model: described secondary chi is 90 ° around the maximum anglec of rotation of column spinner.
As further program of the utility model: described picture sliding shoe is fixed on main scale by dogbolt.
As further program of the utility model: described hollow disk and main scale integral molding.
Compared with prior art, the beneficial effects of the utility model are: described a kind of Teaching of Economics drawing rule, structure is simple, easy to carry, good fixing effect, can draw parallel lines, annulus, concentric circles, different angles ray, the circle drawn be carried out to decile, vertical line segment and draw the tangent line of annulus, meet the drawing requirement in economics, there is memory function, increase the diversity of drawing rule function.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of I shape magnet in the utility model.
In figure: 1-I shape magnet, 2-dial, the hollow disk of 3-, 4-positioning pointer, 5-graduation mark, 6-secondary chi, 7-picture pen, 8-main scale, 9-storage U disk, 10-movable block, 11-column spinner, 12-dogbolt, 13-picture sliding shoe, 14-chute.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 2, in the utility model embodiment, a kind of Teaching of Economics drawing rule, comprise I shape magnet 1, secondary chi 6, main scale 8 and picture sliding shoe 13, described main scale 8 is provided with chute 14, movable block 10 and secondary chi 6 is embedded with in chute 14, by column spinner 11 auxiliary connection chi 6 on movable block 10, secondary chi 6 is 90 ° around the maximum anglec of rotation of column spinner 11, and namely secondary chi 6 is vertical with main scale 8, main scale 8 both sides and secondary chi 6 are equipped with graduation mark 5, slide respectively and be provided with a picture sliding shoe 13 in main scale 8 both sides, picture sliding shoe 13 is fixed on main scale 8 by dogbolt 12, picture sliding shoe 13 end is provided with picture pen 7, main scale 8 one end is provided with storage U disk 9, main scale 8 other end is provided with hollow disk 3, hollow disk 3 and main scale 8 integral molding, hollow disk 3 inside is inlaid with I shape magnet 1, I shape magnet 1 upper surface is provided with dial 2, hollow disk 3 is provided with the positioning pointer 4 towards dial 2.
When carrying out Teaching of Economics drawing, first I shape magnet 1 is adsorbed on blackboard, by the picture sliding shoe 13 of mobile main scale 8 both sides, two parallel lines can be drawn; Adjust the position of mobile main scale 8 both sides picture pen 7 respectively, make main scale 8 rotate the concentric circles that can draw two different radiis around I shape magnet 1, also can draw circle separately; By rotating main scale 8, make positioning pointer 4 point to different angles on dial 2, the picture pen 7 of mobile main scale 8 side can draw the ray of multiple angle, can also carry out decile, meet in economics the demand of drawing pie chart to the circle drawn; The position of moving sets chi 6, draws vertical line segment by main scale 8 with secondary chi 6; Also by the position of moving sets chi 6, the tangent line of annulus can be drawn; Secondary chi 6 is placed in the chute 14 on main scale 8, is easy to carry; The storage U disk 9 of main scale 8 end increases the diversity of drawing rule function, realizes memory function.
Operation principle of the present utility model is: described a kind of Teaching of Economics drawing rule, structure is simple, easy to carry, good fixing effect, parallel lines, annulus, concentric circles, different angles ray can be drawn, the circle drawn carried out to decile, vertical line segment and draw the tangent line of annulus, meet the drawing requirement in economics, there is memory function, increase the diversity of drawing rule function.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
