Description

A kind of Combined ruler for mathematical education
Technical field
The invention belongs to teaching aid field, specifically a kind of Combined ruler for mathematical education.
Background technology
At present, the religion chi used in mathematical education mostly is independent setting, has ruler respectively, protractor, the educational aid that set square etc. are different, independently teaching body is not easy to greatly take, also very inconvenience, brings great inconvenience to the teaching of teacher in use.
Summary of the invention
The present invention, in order to make up the defect of prior art, provides a kind of a kind of Combined ruler for mathematical education facilitating teachers ' teaching to use.
The present invention is achieved through the following technical solutions:
A kind of Combined ruler for mathematical education, comprise ruler plate, difference equipped amount hornwork inner panel and protractor outside plate on ruler plate, ruler plate two ends are provided with extension plate snap close and lower extension plate snap close, upper extension plate snap close is built with upper extension plate, lower extension plate is built with lower extension plate, and the ruler plate of side, lower prolongation pole is provided with lower extension plate angle line.
Concrete, described protractor inner panel is provided with handle.
Concrete, described ruler plate is provided with ruler plate length scales.
Concrete, described upper extension plate snap close and lower extension plate snap close are screw thread loosing and tightening structure, and upper extension plate and lower extension plate can be gone up centered by extension plate snap close and lower extension plate snap close 360 degree and rotate.
The invention has the beneficial effects as follows: effectively multiple teaching aid is optimized and combination, make teacher in teaching process, use a teaching aid can complete all teachings, bring great convenience to the teaching of teacher.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, concrete explanation is done to the present invention.
Accompanying drawing 1 is structure chart of the present invention;
Accompanying drawing 2 is front view of the present invention;
In figure, 1 ruler plate, 2 protractor inner panels, 3 protractor outside plates, 4 handles, 5 times extension plate angle lines, extension plate on 6,7 ruler plate length scales, extension plate snap close on 8,9 times extension plate snap closes, 10 times extension plates.
Detailed description of the invention
Accompanying drawing 1,2 is a kind of specific embodiment of the present invention.A kind of Combined ruler for mathematical education of this invention, comprise ruler plate, difference equipped amount hornwork inner panel and protractor outside plate on ruler plate, ruler plate two ends are provided with extension plate snap close and lower extension plate snap close, upper extension plate snap close is built with upper extension plate, lower extension plate is built with lower extension plate, and the ruler plate of lower extension plate side is provided with lower extension plate angle line.
Concrete, described protractor inner panel is provided with handle.
Concrete, described ruler plate is provided with ruler plate length scales.
Concrete, described upper extension plate snap close and lower extension plate snap close are screw thread loosing and tightening structure, and upper extension plate and lower extension plate can be gone up centered by extension plate snap close and lower extension plate snap close 360 degree and rotate.
A kind of Combined ruler for mathematical education of this invention, during use, this combination ruler lies on blackboard by hand-held handle 4, protractor inner panel 2 and protractor outside plate 3 is all carved with angular marking, can measures according to angle on blackboard, dihedral of painting imparts knowledge to students; Ruler plate 1 is provided with ruler plate length scales 7, when needing picture straight line, the reversion of this combination ruler is drawn straight line by ruler plate 1 side, time as inadequate in length, upper extension plate 6 and lower extension plate 10 can be passed through upper extension plate snap close 8, lower extension plate snap close 9 carries out rotation and fits, and extends the length of picture straight line; Also by combining upper extension plate 6 and lower extension plate 10, control lower extension plate 10 and the angle of ruler plate 1 by lower extension plate angle line 5 to be combined into different triangles by chalk and directly to draw on blackboard, greatly saved teacher constantly take measurement of an angle in teaching process carry out paint explanation process, improve efficiency of giving lessons, bring great convenience to numerous teachers and students.
