Abstract
The utility model discloses a multifunctional mathematical teaching ruler. The multifunctional mathematical ruler comprises a straight ruler (1), wherein an angle measuring scale (5) is integrally connected at the middle position of the straight ruler (1). The multifunctional mathematical ruler is characterized in that a plurality of holes are arranged on the angle measuring scale (5), a rotating ruler (2) is rotatably connected on one end of the straight ruler (1), and the other end of the straight ruler (1) is connected with a chalk sleeve (11) via a circle drawing wire (10).
Description
Technical field
The utility model belongs to the teaching aid technical field, relates to a kind of multifunctional mathmatical teaching chi specifically.
Background technology
In the mathematical education process, teacher often need carry multiple drawing instrument at present, convenient various straight lines, angle, the circle etc. drawn, and existing drawing appliance function ratio is more single, can only draw straight line as ruler, protractor is combined to draw the angle with ruler, and compasses are used for draw circles etc.; In addition, these apparatus generally disperse to place, and teacher is very inconvenient when carrying, and has reduced efficiency of teaching.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, provides a kind of simple in structure, easy to use, can draw multiple figure, the multifunctional mathmatical that is convenient for carrying teaching chi.
For addressing the above problem, the utility model by the following technical solutions:
A kind of multifunctional mathmatical teaching chi, comprise ruler, the centre position of described ruler is connected with the angular surveying chi, and described angular surveying chi is provided with several holes, a wherein end of described ruler is rotatably connected to rotary ruler, and the other end of described ruler is connected with chalk sleeve by drawing round line.
Below be further improvement of the utility model:
Be connected by trip bolt between described rotary ruler and the ruler, the outside of described rotary ruler is provided with disk, and described disk is connected with rotary ruler by trip bolt.
Further improve:
Described angular surveying chi is provided with rectangular opening.
Further improve:
The position that is positioned at the rectangular opening below on the described angular surveying chi offers the right angled triangle hole.
Further improve:
The position that is positioned at rectangular opening one side on the described angular surveying chi offers slotted eye.
Further improve:
The position that is positioned at the slotted eye below on the described angular surveying chi is provided with the isosceles right triangle hole.
Further improve:
The both sides of described ruler, the both sides of rotary ruler are respectively equipped with scale, and the circumferencial direction of described disk is provided with scale.
The utility model adopts technique scheme, the setting of rotary ruler can make things convenient for the teacher to draw the angle of various angles, chalk put into to draw the stretching circle of drawing of circle line behind the chalk sleeve, rectangular opening can make things convenient for teacher's rectangle that draws fast, the setting in right angled triangle hole can make things convenient for teacher's right angled triangle that draws fast, the setting of slotted eye can make things convenient for teacher's ellipse that draws fast, and the setting in isosceles right triangle hole can make things convenient for teacher's isosceles right triangle that draws fast.
Be described further below in conjunction with the accompanying drawing the technical solution of the utility model.
