Description
Technical field
The utility model relates to teaching assistant product field, relates in particular to a kind of international economic and trade special ruler.
Background technology
The student of the International Economics and Trade Specialization education system of answering grasps the basic theories of economics basic theories and international economy, international trade, grasp international, the ABC of trade, understand the socioeconomic status in major country and area, be familiar with current international trade rule and convention, have the basic skills of being engaged in foreign trade work.The international economic and trade specialty is when adding up, often need to draw some diagram curve, in order to show that different signs often need to use different figures to replace, but making at present diagram curve use chi tool is all some function singlenesses, sometimes need to select repeatedly different chi tools in order to make some diagram curve, concrete operations are cumbersome, and operating efficiency is lower.And ruler of the prior art is generally ruler or set square, and the shape function is relatively fixing, but when drawing the irregular figure such as polygon, very inconvenient, reduce teacher's operating efficiency.
The utility model content
The utility model is for the prior art above shortcomings, novel a kind of international economic and trade special ruler is provided, the ruler that integrates multiple figure, different graphic on ruler can be used for drawing different signs, and main scale and turn the round hole at the connection rotating shaft middle part of chi, can articulate rope or link etc. and be convenient to carrying of ruler, alleviate teacher's workload.
The purpose of this utility model is to be achieved through the following technical solutions:
a kind of international economic and trade special ruler, comprise main scale, turn chi, described main scale and the described chi both sides of turning are equipped with scale, described main scale is connected by connection rotating shaft with the described chi that turns, described connection rotating shaft middle part is provided with round hole, described main scale left side is provided with the picture point template, draw the circle template, described main scale middle part is provided with protractor, described protractor is connected with main scale by rotating shaft, described protractor is provided with groove, described main scale right side is provided with picture fork template, described turning from left to right is provided with the five-pointed star template successively on chi, the right angle template, Deng cheek board, the rectangle template, described main scale and the described chi that turns are made by plastics, described main scale surface is provided with rubber layer, the rubber layer surface is provided with anti-slip veins.
Described main scale surface is provided with handgrip.
The utility model beneficial effect: reasonable in design is practical, the novelty that is skillfully constructed, and easy to use, a chi can be drawn out multiple different figure, is easy to carry, and alleviates teacher's workload.
Description of drawings
Fig. 1 is international economic and trade special ruler structural representation described in the utility model.
In figure:
The 1-main scale; 2-draws point template; 3-draws the circle template; The 4-protractor; The 5-groove; 6-draws the fork template; The 7-connection rotating shaft; 8-circle hole; The 9-rotating shaft; 10-turns chi; 11-five-pointed star template; 12-right angle template; The cheek boards such as 13-; 14-rectangle template; The 15-scale.
The specific embodiment
The below is described in further detail the utility model according to drawings and embodiments:
as shown in Figure 1, a kind of international economic and trade special ruler of the present utility model, comprise main scale 1, turn chi 10, described main scale 1 is made by plastics with the described chi 10 that turns, plastic quality is light and cost is lower, described main scale 1 is all that both sides are provided with scale 15 with the described chi 10 that turns, convenient like this use, described main scale 1 is connected by connection rotating shaft 8 with the described chi 10 that turns, turning chi 10 can rotate by connection rotating shaft 8, described connection rotating shaft 8 middle parts are provided with round hole 8, can articulate annulus or lanyard on circle hole 8 to facilitate carrying of special ruler, described main scale 1 left side is provided with picture point template 2, draw circle template 3, draw point template 2 and be used for the picture point operation, draw circle template 3 and be used for the operation of picture circle, described main scale 1 surface is provided with rubber layer, the rubber layer surface is provided with anti-slip veins, prevent that effectively ruler from skidding.Described main scale surface is provided with handgrip, picks up during convenient the use.described main scale 1 middle part is provided with protractor 4, protractor 4 is used for measuring angle, also available quantity hornwork 4 outward flanges carry out the operation of picture semicircle, described protractor 4 is connected with main scale 1 by rotating shaft 9, protractor 4 can rotate at main scale 1 middle part by rotating shaft 9, described protractor 4 is provided with groove 5, groove 5 can be used for picture half arc, described main scale 1 right side is provided with picture fork template 6, draw fork template 6 and be used for the operation of picture fork, described turning from left to right is provided with five-pointed star template 11 successively on chi 10, right angle template 12, Deng cheek board 13, rectangle template 14, above-mentioned four templates are respectively used to the picture five-pointed star, square, capable and the rectangle of equilateral triangle.
During use, can produce use from main scale 1 lower end with turning chi 10 according to different demands, the used time directly is not placed on the normal use that main scale can not have influence on main scale 1 for 1 time, if need picture semicircle or measuring angle, can directly operate with the protractor 4 on main scale 1, add the multiple different graphics template that turns on chi 10 due to main scale 1, so can draw different figures under the prerequisite of carrying a special ruler, need not repeatedly to change chi in drawing process, improve the convenience of carrying and using, improved the operating efficiency of international economic and trade professional teachers.
