Description
Technical field
The utility model relates to teaching aid field, specifically, relates to the special-purpose drawing board of a kind of economics.
Background technology
In economics, relate to a lot of statistics, simple shows that by data message statistics is directly perceived not and vivid, people are not easy to understand, and therefore, have used a large amount of diagramatic ways to indicate statistics in economics, for example, coordinate curve, block diagram and pie chart etc., during teaching, teacher sometimes needs to draw fast statistical chart temporarily, utilizing existing educational aid to draw wastes time and energy, and accuracy is not high.This is the deficiencies in the prior art part.
Utility model content
The technical problems to be solved in the utility model is to provide the special-purpose drawing board of a kind of economics, draws convenient, improves the efficiency of drawing.
The utility model adopts following technological means to realize goal of the invention:
The special-purpose drawing board of a kind of economics, comprise square magnetic white board, it is characterized in that: four limits of described square magnetic white board are respectively arranged with upper groove, low groove, left groove and right groove, between described upper groove and low groove, be provided with vertical rule, between described left groove and right groove, be provided with horizontal rule, the upper end of described square magnetic white board is provided with hitch, the lower end of described hitch is provided with annulus, the periphery mark of described annulus has angle, the center of described annulus is provided with central shaft, described annulus is connected with described central shaft, described central shaft is connected with the slide rule that can rotate along described central shaft, the other end of described slide rule stretches out described annulus.
As the further restriction to the technical program, described central shaft is connected with described annulus by one group of iron wire.
As the further restriction to the technical program, described hitch comprises fixed leg and lanyard, and the lower end of described lanyard connects described annulus.
As the further restriction to the technical program, described slide rule is flexible slide rule.
As the further restriction to the technical program, the top of described slide rule is provided with circular hole, on described circular hole, is provided with paintbrush, and described circular hole and paintbrush are threaded connection.
Compared with prior art, advantage of the present utility model and good effect are: upper groove of the present utility model, low groove, left groove and right groove are for fixing vertical rule and horizontal rule, promote vertical rule and can slidably reciprocate with horizontal rule, thereby draw the coordinate curve needing; Slide rule of the present utility model can rotate along central shaft, on annulus, be provided with angle, thereby utilize paintbrush to draw the pie chart of corresponding angle, paintbrush can move up and down in circular hole, while adjusting brush tip higher than annulus, can regulate the length of slide rule, thereby draw the pie chart of different radii, while not using, annulus can be suspended on fixed leg, saves space.The utility model is novel, simple in structure, suitable applying.
Accompanying drawing explanation
