Abstract

The utility model relates to a multifunctional set square, and belongs to the technical field of teaching aids. The technical scheme is that the multifunctional set square comprises a right-angle set square body (1); at least one round nail (2) is arranged on the right-angle set square body; a strap-shaped groove (3) is formed on the right-angle set square body through taking the round nail as a starting point; two acute angles of the right-angle set square body are respectively 60 degrees and 30 degrees; a right-angled isosceles triangle (4) is formed on the right-angle set square body; and two acute angles of the isosceles triangle are both 45 degrees. The utility model has the positive benefits that the multifunctional set square has functions of two set squares and a compass at the same time, is the same as one set square in shape, size and weight, can measure vertical lines or oblique lines, and also can draw circles of any diameters; and one multifunctional set square can serve three functions, so that the cost of the product is greatly lowered, the multifunctional set square is conveniently carried and used, and the actual problem of teaching is solved.

Description

A kind of multifunctional triangle
Technical field
The utility model relates to a kind of multifunctional triangle, belongs to the teaching aid technical field.
Background technology
At present, the teaching aid function singlenesses such as set square that school is commonly used, the teacher of dogmata section goes up need be with two set squares (right angle triangle, an isoceles triangle plate) and compasses class hour, and the subject matter of existence is: quantity is many, carries inconvenience; During use, function singleness, two set squares, compasses are brought and are removed very not aspect.
The utility model content
The purpose of the utility model provides a kind of multifunctional triangle, integrates the function of two set squares and compasses, carries and uses all easily, solves the problems referred to above that background technology exists.
The technical scheme of the utility model is: a kind of multifunctional triangle, comprise a right angle trigonometry plate body, and on the right angle trigonometry plate body, be provided with a center of circle nail at least, be starting point with center of circle nail, on the right angle trigonometry plate body, be provided with banded groove.
Said cingulum sulcus well width is less than or equal to the diameter of teaching with chalk, during use, chalk inserted in the banded groove, and be the center of circle with center of circle nail, the circle of the arbitrary diameter that can draw, the right angle trigonometry plate body has possessed the basic function of compasses fully.Because banded groove is continual, the circle of the arbitrary diameter that can draw satisfies need of teaching.
Said center of circle nail is positioned at the bight of right angle trigonometry plate body, and banded groove is provided with scale along the hypotenuse straight line of right angle trigonometry plate body on banded groove side, is convenient to intuitively see drawn radius of a circle numerical value.
With center of circle nail is starting point, on the right angle trigonometry plate body, is provided with several and center of circle pitch of nails from the hole of not waiting.
The diameter in said hole, inserts chalk in the different holes during use more than or equal to the diameter of teaching with chalk, is the center of circle with center of circle nail, the circle of the different-diameter that can draw, and the right angle trigonometry plate body has also possessed the basic function of compasses.
Said several holes is arranged in a straight line, and each hole all is provided with corresponding scale, can see the radius distance value of this drawn circular arc in hole intuitively.
Three bights of right angle trigonometry plate body all are provided with center of circle nail; Each limit portion of right angle trigonometry plate body all is provided with banded groove; What perhaps have is provided with banded groove, and what have is provided with several holes, and for example: limit of right angle trigonometry plate body is provided with banded groove; Another limit is provided with several holes, shared same center of circle nail.
Two acute angles of said right angle trigonometry plate body are respectively 60 degree and 30 degree, on the right angle trigonometry plate body, have a right angled isosceles triangle, and these leg-of-mutton two acute angles are 45 degree, and a set square can be used as the use of two set squares; All be provided with scale on the limit of each set square.
Said right angle trigonometry plate body is provided with handle, and is easy to use.
The good effect of the utility model is: multifunctional triangle has possessed the function of two set squares and compasses simultaneously, and shape size, weight are with a set square the same; Can measure vertical line, also can measure oblique line, can also draw the circle of arbitrary diameter, one can push up three with, reduced the cost of product greatly, easy to carry and use, solved the practical problem of teaching.
Description of drawings
Accompanying drawing 1 is the utility model embodiment sketch map;
Among the figure: right angle trigonometry plate body 1, center of circle nail 2, banded groove 3, right angled isosceles triangle 4, handle 5, scale 6, hole 7.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further specified through embodiment.
In an embodiment, a kind of multifunctional triangle comprises a right angle trigonometry plate body 1, on the right angle trigonometry plate body, is provided with a center of circle nail 2 at least, is starting point with center of circle nail, on the right angle trigonometry plate body, is provided with banded groove 3.
Said cingulum sulcus well width is less than or equal to the diameter of teaching with chalk, during use, chalk inserted in the banded groove, and be the center of circle with center of circle nail, the circle of the arbitrary diameter that can draw, the right angle trigonometry plate body has possessed the basic function of compasses fully.Because banded groove is continual, the circle of the arbitrary diameter that can draw satisfies need of teaching.Said center of circle nail is positioned at the bight of right angle trigonometry plate body, and banded groove is provided with scale 6 along the hypotenuse straight line of right angle trigonometry plate body on banded groove side, is convenient to intuitively see drawn radius of a circle numerical value.
With center of circle nail is starting point; On the right angle trigonometry plate body, be provided with several and center of circle pitch of nails from the hole 7 of not waiting, the diameter in said hole is more than or equal to the diameter of imparting knowledge to students with chalk, during use; Chalk is inserted in the different holes; With center of circle nail is the center of circle, the circle of the different-diameter that can draw, and the right angle trigonometry plate body has also possessed the basic function of compasses.Said several holes is arranged in a straight line, and each hole all is provided with corresponding scale, can see the radius distance value of this drawn circular arc in hole intuitively.
Limit of right angle trigonometry plate body is provided with banded groove 3, and another limit is provided with several holes 7, shared same center of circle nail 2.
Two acute angles of said right angle trigonometry plate body are respectively 60 degree and 30 degree, on the right angle trigonometry plate body, have a right angled isosceles triangle 4, and these leg-of-mutton two acute angles are 45 degree, and a set square can be used as the use of two set squares; All be provided with scale on the limit of each set square.Said right angle trigonometry plate body is provided with handle 5, and is easy to use.
