Description
Technical field
The utility model relates to a kind of drawing board, is specifically related to the special drawing board of a kind of economics, belongs to Science of Economics.
Background technology
Economics is the theory of rule of the production of researching value, circulation, distribution, consumption.The research object of economic research object and natural science, social science is same objective law.Economics is a subject, is organic whole, is the science of the various economic activity of research human society on stages and various corresponding economic relation and operation thereof, the rule of development.Economic core concept is material scarcity and efficent use of resources.Often can need to draw various data form and curve in economics research; these data forms and curve are the important supplementary means of economics research; therefore; the accuracy of drawing data form and curve directly affects the accuracy of economics research; at present, drawing instrument conventional in economics is all simple set square, compasses and ruler, and during drawing data curve, efficiency is very low; and poor accuracy, impact analysis and result of calculation.
Summary of the invention
The utility model is all simple set square, compasses and ruler to solve drawing instrument conventional in economics, and during drawing data curve, efficiency is very low, and poor accuracy, the problem of impact analysis and result of calculation, and then the special drawing board of a kind of economics is proposed.
The utility model is the technical scheme taked that solves the problem: the utility model comprises the first ruler, second ruler, rotating shaft, first alignment pin, second alignment pin, first bent chain tape and the second bent chain tape, one end of first ruler is connected by rotating shaft one end with the second ruler, the upper surface of the first ruler has the first chute along its length, the upper surface of the second ruler has the second chute along its length, one end of described first bent chain tape is arranged in the first chute by the first alignment pin, one end of described second bent chain tape is installed in the second chute by the second alignment pin.
The beneficial effects of the utility model are: the position being regulated the first bent chain tape, the second bent chain tape when 1, the utility model uses by the first alignment pin and the second alignment pin, disposable for each data point in figure whole link can be got up by the first bent chain tape and the second bent chain tape, improve drawing efficiency, avoid the plotting error that repeatedly attachable mechanical stage body causes; 2, fixed block of the present utility model can make the utility model realize drawing plane by fixing for the first ruler on the teaching board, also can draw on vertical plane or inclined-plane simultaneously; 3, the hollow shaft in the utility model can accurate mark data points on figure, improves the degree of accuracy of drawing.
