Abstract
The utility model relates to a kind of multi-functional ruler-compasses plotter, belongs to teaching aid field.Be made up of index dial 1, chi leg 2, chalk sleeve 3, holding frame 4, connecting bolt 5, chi pin 6, No. two connecting bolts 7, No. two chi legs 8, slide-rule dial line 9, hand nutting 10, angle index lines 11.The feature of this ruler is that it is combined innovation on the basis of existing compasses, use of both can having mapped as general compasses; Can be stuck by two parts when also two of a ruler chi leg can be separated into 180 °, make it be held in straight line, add high scale and just can be used as a long ruler and use.Angle index line 11 on index dial 1 has two effects, both can be used for the angle that measurement two chi legs separate, and so not only can take measurement of an angle as common protractor but also can directly draw angle at any angle; Can be used for again the distance determining that two chi leg ends separate, when namely using as compasses, determine picture radius of a circle.
Description
Technical field
The utility model relates to a kind of multi-functional ruler-compasses plotter, belongs to teaching aid field.
Background technology
Teaching aid is industrial production enterprise is that schoolman conveniently imparts knowledge to students and special a kind of instrument.The teaching aid that school uses is diversified, according to different study purposes, has the teaching aid of a lot of function singleness.The drawing ruler and gauge that we study be for difference study purposes can the teaching aid of multi-functional use.This drawing ruler and gauge is powerful, easy to operate, is easy to carry, and diverse in function is suitable for applying in different environments.
Summary of the invention
The purpose of this utility model integrates multi-functional, long for the time solving teacher's blackboard drawing, the problem that learning efficiency is low.
The technical scheme that this practical information adopts comprises index dial (1), chi leg (2), chalk sleeve (3), holding frame (4), connecting bolt (5), chi pin (6), No. two connecting bolts (7), No. two chi legs (8), slide-rule dial line (9), hand nutting (10), angle index line (11), index dial (1) and a chi leg (2) are integrally, a chi leg (2) is connected by a connecting bolt (5) with holding frame (4), chalk sleeve (3) is clamped and connected by holding frame (4) and a chi leg (2), chi pin (6) is connected with No. two chi legs (8) by No. two connecting bolts (7), slide-rule dial line (9) is positioned at No. two chi leg (8) surfaces, a chi leg (2) is connected by hand nutting (10) with No. two chi legs (8), angle index line (11) is positioned at index dial (1) surface.
The beneficial effects of the utility model are: its mechanism is simple, easy to operate, is suitable for using at the different environment that needs.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is angle gage structure schematic diagram of the present utility model.
Detailed description of the invention
In order to describe multi-functional ruler-compasses feature, function is easy to understand, in conjunction with the structural representation map analysis of ruler.
As shown in Figure 1 and Figure 2, multifunctional drawing ruler comprises index dial 1, chi leg 2, chalk sleeve 3, holding frame 4, connecting bolt 5, chi pin 6, No. two connecting bolts 7, No. two chi legs 8, slide-rule dial line 9, hand nutting 10, angle index lines 11.Index dial 1 and, chi leg 2 one, a chi leg 2 is connected by a connecting bolt 5 with holding frame 4, chalk sleeve 3 is clamped and connected by holding frame 4 and a chi leg 2, chi pin 6 is connected with No. two chi legs 8 by No. two connecting bolts 7, slide-rule dial line 9 is processed on No. two chi leg 8 surfaces, a chi leg 2 is connected by hand nutting 10 with No. two chi legs 8, and angle index line 11 is processed on index dial 1 surface.Angle index line 11 on index dial 1 has two effects, both can be used for the angle that measurement two chi legs separate, and so not only can take measurement of an angle as common protractor but also can directly draw angle at any angle; Can be used for again the distance determining that two chi leg ends separate, when namely using as compasses, determine picture radius of a circle.
The utility model makes and uses more convenient, on classroom, can improve the drawing efficrence of teacher, easy to use.
