Description
Technical field
This utility model relates to Teaching of Economics device technique field, is specifically related to Teaching of Economics bar diagram diagraph.
Background technology
When Economics Courses is imparted knowledge to students, teacher's needs are used for the corresponding relation explaining between each parameter on blackboard with drawing with coloured chalk bar graph.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of can Fast Drawing bar graph, the suitability is strong, be easy to regulate in bar graph the Teaching of Economics bar diagram diagraph of spacing between each group of figure.
For solving above-mentioned technical problem, this utility model provides techniques below scheme: Teaching of Economics bar diagram diagraph, the L-type accessory plate formed including being mutually perpendicular to by transverse slat and stringer board；Including the drawing rule being 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；Including sucker, described sucker is arranged at the crossfoot back side, and described sucker height is equal to the crossfoot back side and transverse slat back side spacing；Also including fastening screw, described transverse slat has been embedded in cross sliding tray, and described cross sliding tray is mutually perpendicular to by slide block slot and drawing rule groove and is formed, and is sliding combined with slide block in described slide block slot, and described slide block width is more than drawing board well width；Described slide block both sides extend through and are provided with the groove corresponding with linear foot, and described linear foot is through cross sliding tray and scalable is placed in groove；Described transverse slat front is provided with graduation mark；Described transverse slat front is embedded with the binding groove corresponding with fastening screw, and described binding groove is communicated in slide block slot and described binding groove height less than slide block slot height, and described fastening screw is connected in binding groove and holds out against in slide block through binding groove is threaded.
On such scheme basis preferably, described stringer board upper surface is provided with graduation mark.
This utility model compared with prior art has the beneficial effect that wherein, and drawing rule can do in groove flexible, it is simple to change the linear foot length for drawing, and then suitable in the drafting of differing heights bar graph, and drawing efficiency is high；Wherein, drawing rule can realize sliding in transverse slat with coordinating of slide block slot by slide block, namely facilitate drawing rule for regulating in bar graph spacing between each group of figure, to improve its suitability, and fastening screw holds out against in slide block through binding groove, it is simple to realize fixing to keep spacing positioning stablity between each group of figure slide block.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is the cross sliding tray structural representation of this utility model.
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-sucker, 5-fastening screw, the cross sliding tray of 6-, 61-slide block slot, 62-drawing rule groove, 7-slide block, 71-groove, 8-binding groove.
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, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.
In description of the present utility model, it will be appreciated that, term " longitudinal direction ", " transverse direction ", " on ", D score, "front", "rear", "left", "right", " vertically ", " level ", " top ", " end ", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, it is for only for ease of description this utility model, rather than the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.
Seeing figures.1.and.2 it can be seen that Teaching of Economics bar diagram diagraph, the L-type accessory plate 1 formed including being mutually perpendicular to by transverse slat 11 and stringer board 12, described stringer board 12 upper surface is provided with graduation mark 3；Including the drawing rule 2 being 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；Including sucker 4, described sucker 4 is arranged at crossfoot 21 back side, and described sucker 4 is highly equal to crossfoot 21 back side and transverse slat 11 back side spacing；Also include fastening screw 5, described transverse slat 11 has been embedded in cross sliding tray 6, described cross sliding tray 6 is mutually perpendicular to by slide block slot 61 and drawing rule groove 62 and is formed, and is sliding combined with slide block 7 in described slide block slot 61, and described slide block 7 width is more than drawing board slot 62 width；Described slide block 7 both sides extend through and are provided with the groove 71 corresponding with linear foot 22, and described linear foot 22 is through cross sliding tray 6 and scalable is placed in groove 71；Described transverse slat 11 front is provided with graduation mark 3；Described transverse slat 11 front is embedded with the binding groove 8 corresponding with fastening screw 5, described binding groove 8 is communicated in slide block slot 61 and described binding groove 8 height less than slide block slot 61 height, and described fastening screw 8 is connected in binding groove 7 and holds out against in slide block 5 through binding groove 7 is threaded.
Wherein, drawing rule 2 can do in groove 71 flexible, it is simple to changes the linear foot 22 length for drawing, and then suitable in the drafting of differing heights bar graph, and drawing efficiency is high；Wherein, drawing rule 2 can realize sliding in transverse slat 11 with coordinating of slide block slot 61 by slide block 7, namely facilitate drawing rule for regulating in bar graph spacing between each group of figure, to improve its suitability, and fastening screw 5 holds out against in slide block 7 through binding groove 8, it is simple to realize fixing to keep spacing positioning stablity between each group of figure slide block 7.
