Abstract

The utility model relates to a multifunctional set square for measuring angle and position, comprising a plate A and a plate B which are respectively formed by a transparent plate main body, a protractor on the main body, a length scale and a hollow part. The inner circle of the protractor is provided with a corner scale. The plate A is an isosceles right triangle plate. The plate B is a right triangle plate with two inner angles being 30 degrees and 60 degrees. The utility model can be used as a tool for student to know number axis and negative number knowledge because the plate main body is provided with protractor, length scale, angle scale, arc hollow and scale extension lead in order to measure angle, draw angle and measure position. The distance on a picture can be measured when measuring an angle and the distance on the picture can be marked when drawing an angle. The plate A and the plate B are used together, so the utility model can be used as a tool for measuring the position of a target point. The utility model has the advantages of simple element, low cost, convenient use, more functions, and the like.

Description

Angulation amount position multifunctional triangle

One, technical field

The utility model relates to a kind of teaching aid, especially a kind of angulation amount position multifunctional triangle.

Two, background technology

The set square that existing student uses can only or be drawn 30 degree, 45 degree, 60 degree, 90 degree and is combined into special angles such as 105 degree, 150 degree, can not draw angle arbitrarily; Existing protractor has only angulation and draws the function at angle, do not mark " north ", " south ", " west ", " east " and length scale, this distinguishes the orientation of each impact point on the plane to the student, draw plane, the trip route map, measure certain map range and bring many inconvenience, and the radius of protractor is generally more than 4.5cm, there is not hollow out in many protractor semicircles, when drawing the angle, the length on a limit at angle must be more than or equal to 4.5cm, and in fact the student when graphing, under many circumstances, the length of side at angle does not need 4.5cm, and leaves the position that the student draws in a lot of operation paper for and do not have so much yet, but when the length of indivedual figures surpasses the radius of protractor, the Len req that can not directly draw again needs to take in addition one prolong original limit to chi and just can finish, and this makes troubles for again student's graphing.

Three, utility model content

But the purpose of this utility model provides a kind of not only angulation and draws the angle, but also can measure the set square in orientation, and it can overcome the problems referred to above that prior art exists.

For achieving the above object, the utility model is achieved in that

It comprises A plate and B plate, constitute by transparent plate body and the protractor on the body and length scale and hollow out respectively, described protractor number of degrees inner ring also is provided with position, angle scale, the A plate is the isosceles right angle triangle, the B plate is the right angle triangle that interior angle has 30 ° and 60 °, length scale on the described A plate is located on the set square hypotenuse, 0cm point on the scale is located at set square hypotenuse centre position and corresponding with protractor semicircle centre point, be carved with-6 ,-5 ,-4 successively,-3 ,-2 ,-1,0,1,2,3,4,5,6 characters; Circle centre position is carved with " west, north, east " Chinese character; Radius 2cm place is provided with the wide hollow out of 2～3mm respectively between radius 1.5cm place between the radius 4.5cm place between 70 °～110 °, 0 °～80 ° and 100 °～180 °; Length scale on the B plate is located at long right-angle side, identical on protractor and the A plate, and circle centre position is carved with " west, south, east " Chinese character; Between the radius 1.5cm place between 10 °～80 °, 5 °～35 ° and the radius 4.5cm place between 70 °～110 °, and the radius 2cm place between 110 °～170 °, be respectively equipped with the wide hollow out of 2～3mm.

Be respectively equipped with the extension scale line between 0 °～60 ° and 120 °～180 ° at A plate two right-angle sides and the protractor radius 4.5cm place; Be provided with the extension scale line between 0 °～60 ° at shorter right-angle side of B plate and the protractor radius 4.5cm place.

Because the utility model is provided with protractor, length scale, position, angle scale and hollow out on the plate body, but can reach both angulation picture angles, can measure the purpose in orientation again, have advantages such as member is simple, with low cost, easy to use, function is more.

Four, description of drawings

Concrete structure of the present utility model is provided by the following drawings.

Fig. 1 is the utility model A plate structure schematic diagram.
