Description
Technical field
The utility model relates to Teaching of Economics technical field, specifically relates to Teaching of Economics bar chart plotter.
Background technology
When Economics Courses is imparted knowledge to students, teacher need with ruler on blackboard with drawing with coloured chalk bar graph for explaining the corresponding relation between each parameter, but draw bar graph with ruler, efficiency is lower, is unfavorable for improving the quality of teaching.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of can Fast Drawing bar chart, Teaching of Economics bar chart plotter that accuracy is high.
For solving the problems of the technologies described above, the utility model provides following technical scheme: Teaching of Economics bar chart plotter, comprises and that formed L-type accessory plate mutually vertical by transverse slat and stringer board; Comprise the drawing rule be made up of two linear foots arranged in parallel and a crossfoot, described crossfoot is vertically installed between two linear foots, and described linear foot upper surface is provided with graduation mark; Described transverse slat closely runs through from the side of drawing rule and is provided with several groove groups, and described each groove group comprises two grooves corresponding with linear foot, and described linear foot is scalable to be placed in groove; Comprise sucker, described sucker is arranged at the crossfoot back side, and described sucker height equals the crossfoot back side and transverse slat back side spacing.
On such scheme basis preferably, described transverse slat and stringer board upper surface are provided with graduation mark.
On such scheme basis preferably, described transverse slat and stringer board one-body molded.
On such scheme basis preferably, described linear foot and crossfoot one-body molded.
On such scheme basis preferably, described sucker is arranged at crossfoot back side center position.
The beneficial effect that the utility model compared with prior art has is: wherein, by transverse slat and stringer board are mutually vertical, L-type accessory plate that is that formed may be used for transverse axis and the longitudinal axis of drawing bar chart, the drawing rule be made up of two linear foots arranged in parallel and crossfoot may be used for drawing each bar figure in bar graph, convenient drafting, efficiency is high, and linear foot is by cooperatively interacting can carry out telescopic movable by relative transverse slat with groove, and then can be used for regulating the drafting height of bar graph discal patch figure to improve applicability; Wherein, the crossfoot back side arranges sucker, and sucker height equals the crossfoot back side and transverse slat back side spacing, is convenient to keep linear foot two ends to flush to improve drawing accuracy.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model drawing rule and groove, sucker matching relationship schematic diagram.
Number in the figure is: 1-L type accessory plate, 11-transverse slat, 12-stringer board, 2-drawing rule, 21-crossfoot, 22-linear foot, 3-graduation mark, 4-groove group, 41-groove, 5-sucker.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
In description of the present utility model, it will be appreciated that, term " longitudinal direction ", " transverse direction ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, it is only the utility model for convenience of description, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
See figures.1.and.2 known, Teaching of Economics bar chart plotter, comprises and that formed L-type accessory plate 1 mutually vertical by transverse slat 11 and stringer board 12; Comprise the drawing rule 2 be made up of two linear foots 22 arranged in parallel and a crossfoot 21, described crossfoot 21 is vertically installed between two linear foots 22, and described linear foot 22 upper surface is provided with graduation mark 3; The nearly side from drawing rule 2 of described transverse slat 21 is run through and is provided with several groove groups 4, and described each groove group 4 comprises two grooves 41 corresponding with linear foot 22, and described linear foot 22 is scalable to be placed in groove 41; Comprise sucker 5, described sucker 5 is arranged at crossfoot 21 back side, and described sucker 21 highly equals crossfoot 21 back side and transverse slat 11 back side spacing.
With further reference to Fig. 1, described transverse slat 11 and stringer board 12 upper surface are provided with graduation mark 3, are convenient to accurately draw bar graph transverse axis and the longitudinal axis.Described transverse slat 11 is one-body molded with stringer board 12, can improve its stability.Described linear foot 22 is one-body molded with crossfoot 21, can improve its stability.Described sucker 5 is arranged at crossfoot 21 back side center position, can improve the stationarity that sucker 5 supports.
Wherein, by transverse slat 11 and stringer board 12 are mutually vertical, L-type accessory plate 1 that is that formed may be used for transverse axis and the longitudinal axis of drawing bar chart, and the drawing rule 2 be made up of two linear foots 22 arranged in parallel and crossfoot 21 may be used for each bar figure in drafting bar graph; In bar graph one figure drawn after, to extract out in the drawing rule 2 groove group that from then on bar figure is corresponding 4 and insert in another groove group 4 to carry out the drafting of next group bar figure, convenient drafting, efficiency is high, and linear foot 22 is by cooperatively interacting can carry out telescopic movable by relative transverse slat 11 with groove 41, and then can be used for regulating the drafting height of bar graph discal patch figure to improve applicability; Wherein, crossfoot 21 back side arranges sucker 5, and sucker 5 highly equals crossfoot 21 back side and transverse slat 11 back side spacing, is convenient to keep linear foot 22 two ends to flush to improve drawing accuracy.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
