The radius pore size distribution that also comprises ruler is at metric scale, foot rule and chi scale on, arrange out the radius ordinal number.
The limit that the zero degree initial line of protractor and the working edge of metric scale form, and between the two chi limits to the foot rule working edge of adjacent foot rule, the saturating empty mapping groove that becomes.
Metric scale, foot rule and chi, with the protractor binding site, can exchange setting.
First footpath pore size distribution of bar ruler is combined on the scale.
The utility model is than prior art, and advantage is rational in infrastructure, and one has the mapping angle, length, and the effect of circle, the speed of measuring graphing is very fast, and is few with material, portable preservation.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further explained.
Fig. 1 is a geometry coordinate machine schematic diagram of the present invention.
Fig. 2 is a ruler schematic diagram of the present invention.
Number in the figure 1. geometry coordinate machines, a 2. ruler, 2-2. radius hole, 3. protractor, the 3-1. center of circle, 4. metric scale, 4-1. the metric scale initial point, 4-2. working edge, 5. foot rule, 5-1. the foot rule initial point, 5-2. foot rule working edge, 6. chi, 7. ruler is is 8. surveyed and drawn groove, 9. numeral, 10. scale, 11. material-saving holes.
The specific embodiment
See also accompanying drawing.Fig. 1 is the utility model how much mapping schematic diagrames, and wherein geometry coordinate machine is by geometry coordinate machine 1, bar ruler 2, radius hole 2-2, protractor 3, center of circle 3-1, metric scale 4, working edge 4-2, foot rule 5, foot rule working edge 5-2, chi 6, ruler 7, mapping groove 8, numeral 9, scale 10, material-saving hole 11 constitutes, and it is characterized in that the center of circle 3-1 of the protractor 3 of described geometry coordinate machine 1, with the metric scale initial point 4-1 of metric scale 4 at a point; The zero degree initial line of protractor 3 and the working edge 4-2 of metric scale 4 be at a line, geometry coordinate machine 1 range structure changeable.
Metric scale 4, foot rule 5 pass protractor 3 the zero degree initial line up and down to center of circle 3-1, protractor 3 has adaptive change with metric scale 4 and foot rule 5 on numeral, scale, foot rule initial point 5-1 and metric scale initial point 4-1 coexist on the longitudinal axis, and center of circle 3-1 has solid and hollow form setting.
The radius hole 2-2 that also comprises ruler 7 is distributed in metric scale 4, on foot rule 5 and chi 6 the scale, arranges out the radius ordinal number.The radius value of radius hole 2-2 is provided with by the scale metering unit amount of determining on each yardstick, metric scale 4 with 0.25,0.5,0.75 and 1 millimeter radius unit, the numerical value that numerical value is millimeter is extended in the back, arrange out the diameter precision of drawing and reach 0.5 millimeter, the result of 1 millimeter ordinal number diameter, when the numerical value of mapping radius value surpasses in numeral 9, obtain on the scale 10, the size of radius distance value is to be arranged on metric scale 4, foot rule 5,2-2 hole, the radius hole bit architecture of chi 6 digital high scales, indicate the number of division word reduction general designation on ruler and the protractor, the radius hole 2-2 of ruler 7 extends row's example in the positive negative direction of chi initial point.
