Abstract

The utility model discloses a multifunctional intelligence reinforcing protractor which is in an isosceles right triangle shape. The multifunctional intelligence reinforcing protractor is formed by movably splicing fourth triangle plates in different shapes in a fastening or riveting or stretching or strong magnetic mode. According to the multifunctional intelligence reinforcing protractor, the four triangle plates are integrated and movably spliced to form a large isosceles right triangle plate, and therefore materials are saved, and the multifunctional intelligence reinforcing protractor is convenient to carry. Any base-5 angle can be drawn by effectively combining the four triangle plates. In addition, a 120-degree triangle protractor body can be used for angle measurement, and therefore 360-degree angle measurement can be achieved. Besides angle measurement, length measurement is achieved due to the fact that inch scales and centimeter scales are arranged. The multifunctional intelligence reinforcing protractor can improve the spatial thinking capacity and the digit arithmetic capacity, and has an intelligence reinforcing function while having the learning function.

Description

A kind of multifunctional beneficial mentality protractor

Technical field

The utility model relates to a kind of teaching measuring device field, is specifically related to a kind of multifunctional beneficial mentality protractor.

Background technology

Protractor, set square and ruler are the indispensable instruments that student and engineers and technicians draw, and existing these instruments are all generally single-pieces independently, and number of packages is many, carry, keeping is inconvenient, and meanwhile, cost is high, and instrument disperses, and uses inconvenient.Existing protractor is generally semicircle protractor, function singleness, protractor and set square separate, and set square can only be drawn the angle of several special angles, and rule only has millimeter, now the screen of a lot of electronic products is that inch is unit, and measuring how many millimeters, will to be scaled inch cumbersome.

Utility model content

Utility model object: the purpose of this utility model is in order to solve above the deficiencies in the prior art, provides a kind of multi-functional intelligence development protractor.

Technical scheme: a kind of multifunctional beneficial mentality protractor described in the utility model, be shaped as an isosceles right triangle, formed by four difform set square moving jointings.

Preferably, described moving jointing is the one during snapping, riveted joint, stretching connection or strong magnetic connect.

Preferably, described four difform set squares are respectively equilateral triangle plate, two angles and are the isoceles triangle plate of 30 °, two angles and are respectively the set square of 65 ° and 15 ° and two angles and are respectively the set square of 20 ° and 45 °.

Preferably, described two angles are the isoceles triangle plate of 30 ° and are provided with angle groove.

Preferably, the set square that two angles are respectively 65 ° and 15 ° is provided with inchage unit's groove.

Preferably, the set square that two angles are respectively 20 ° and 45 ° is provided with centimetre length unit's groove.

Beneficial effect: a kind of multifunctional beneficial mentality protractor described in the utility model, closing three is one, moving jointing is in a large isosceles right angle triangle, saves material and is convenient for carrying; Four set squares can draw by effective combination the angle of any 5 systems; Also have in addition 120 ° of triangle protractor angulations, the utility model can be realized 360 ° of angular surveying; Except taking measurement of an angle, the utility model is also provided with inch and centimeter scale, realizes linear measure longimetry; The utility model can also improve the ability of spatial thought and digital operation, has the effect of intelligence development in study.
