Abstract
The utility model discloses a teaching is with multi -functional mapping chi, its characterized in that is personally experienced sth. Part of the body (1) to the rectangle chi that has the scale including four sides: the rectangle chi body length nearly lower part in limit is equipped with one semi -circular little rectangular through -hole (5), and semi -circular little rectangular through -hole outer room is equipped with a semi -circle at a distance from one section size and greatly enhances a through -hole (3), has the sign of angle on semi -circle (6) and half -circular arc face (4) that semi -circular little rectangular through -hole and semi -circular big rectangular through -hole formed, and one hexagon through -hole (2) and one pentagon through -hole (7) are located rectangle chi body upper portion two respectively and are leaned on the tip. Owing to have the structure of rectangle, hexagon, pentagon and protractor on the teaching is with multi -functional mapping chi, so can conveniently draw up parallel lines, rectangle, hexagon, pentagon figure, it has the protractor structure to add, the triangle -shaped of the different contained angles that also can draw up. Reached completely the utility model discloses convenient to carry, can draw the invention mesh of multiple figure.
Description
Technical field
The utility model relates to a kind of teaching aid, particularly relates to a kind of teaching multifunctional drawing ruler.
Background technology
As everyone knows, teacher, when school instruction geometric knowledge, must use numerous teaching aids, as ruler, set square, protractor.Because these teaching aids disperse, use and carry all very inconvenient, particularly drawing parallel lines, rectangle, hexagon, pentagon figure time seem more outstanding.
Utility model content
The purpose of this utility model is to provide a kind of easy to carry, the teaching multifunctional drawing ruler that can draw multiple figure to change the deficiencies in the prior art.Its concrete technical scheme is: teaching multifunctional drawing ruler comprises one or four sideband graduated rectangle chi body, nearly bottom, the long limit of rectangle chi body is provided with a semicircle little rectangular through hole, semicircle little rectangular through hole outer one section, interval size is provided with a semicircle and greatly enhances bar through hole, angled mark on the semicircle that semicircle little rectangular through hole and the large rectangular through hole of semicircle are formed and semicircular arc face, a hexagon through hole and a pentagon through hole are located at rectangle chi body top two respectively by end.
As can be seen from the technical solution of the utility model, owing to teaching multifunctional drawing ruler having the structure of rectangle, hexagon, pentagon and protractor, so parallel lines, rectangle, hexagon, five-sided figure can be drawn easily, add angle gage structure, also can draw the triangle of different angle.And easy to carry, fully meet the goal of the invention that the utility model is easy to carry, can draw multiple figure.
