Abstract

The utility model relates to a multi-purpose triangle and belongs to a triangle for students. The multi-purpose triangle fulfills the aims of being more convenient for the students to use and carry, reducing production cost and increasing use functions by only mading a hollow triangle which contains an angle of 45 degrees and an angle of 75 degrees and has the protractor function, a convex lens, a concave lens, a dotted line groove and a wavy edge on a transparent triangle body with an angle of 30 degrees.

Description

Use set square more
Technical field
The utility model belongs to uses set square more.
Background technology
Before the utility model was made, the set square that the student uses was generally wanted 2 to 3, and the cost height uses and carry inconvenience.
Summary of the invention
Purpose provides a kind ofly to be used and carries set square more easily, reduces cost simultaneously, increases function of use.
The method that the utility model is dealt with problems is: only make the hollow triangle with protractor function, convex lens, concavees lens that contain 45,75 degree angles, and dotted line groove, rippled edge on a transparent right angle trigonometry plate body that contains 30 degree angles.
The beneficial effects of the utility model are that the student uses and carries more conveniently, have reduced cost simultaneously, increase function of use.
Description of drawings
Fig. 1 is a structure vertical view of the present utility model.
Fig. 2 is a dotted line groove place plate body sectional drawing.
The specific embodiment
With reference to Fig. 1, transparent right angle triangle plate bodys [1] that contain 30 degree angles are gone up by 60 degree angle places and are made hollow triangles [2] that contain 45,75 degree angles, 45,75 degree angles of triangle [2] point to respectively the set square plate body 30, an angle of 90 degrees degree.By a length scale [4] and a dotted line groove [5] are arranged on the long right-angle side [3], interval hollow out in the groove [5] when pen is drawn, will stay dotted line on the paper in groove [5]; Length scale [4] prolongs the parallel lines [7] that become to be parallel to short right-angle side [6] every 5 or 10 millimeters.During use,,, and can read parallel wire spacing from length scale [4] along the line and the known straight line parallel of right-angle side [6] picture parallel lines [7] and known straight line coincidence or visual parallel.Rippled edge [8] can be made in hollow triangle [2] 60, on the common limit [9] of miter angle degree, also can be made on the hypotenuse of triangle plate body [1].Indicate the initial point [10] of protractor altogether above the limit [9], having on the limit [11] of hollow triangle [2], [12] with initial point [10] is the angle index [13] on summit, thereby has formed protractor.Extended line [14] is done to right-angle side [6] in limit [12], and crosses and do vertical line [16] with right-angle side [11] intersection point [15], and vertical line [16] is gone up and made symmetrical scale [17] with intersection point [15] to both sides; When making bisector of angle, mobile set square plate body [1] is positioned on the extended line [14] summit at angle, and intersect with the identical value of symmetrical scale [17] place respectively on the both sides at angle, prolongs limit [12] line of being done and be the angular bisector at this angle.[18], [19] are respectively convex lens and concavees lens.

Claims (3)

1. comprise the set square plate body with set square more than one kind, comprise hollow triangle, convex lens, concavees lens, the dotted line groove is characterized in that: one contain 30 the degree angles transparent right angle trigonometry plate body on make contain 45,75 the degree angles the hollow triangle with protractor function, and convex lens, concavees lens, dotted line groove, rippled edge.
2. according to claim 1ly many use set square, it is characterized in that 45,75 of hollow triangle spend angles point to respectively the right angle trigonometry plate body 30, an angle of 90 degrees.
3. according to claim 1 use set square more, it is characterized in that rippled edge is to be made on the hypotenuse of triangle plate body.
