The utility model discloses can make compasses, ruler, protractor combine convenient to use swift, bring the facility of drawing for the teacher in the mathematical education.
Description
[technical field]
The utility model relates to the technical field of teaching aid, the technical field of teaching aid of particularly drawing.
[background technology]
At present, in the process of mathematical education, often need to use compasses, ruler, protractor, but these instruments all individualisms, carry inconvenience.Especially the bad tune of angle when compasses are figure, and the angle mixed up is inconvenient to keep, and this makes troubles and trouble to teacher in teaching process.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, proposes the special drawing teaching aid of a kind of mathematical education, compasses, ruler, protractor can be made to be combined convenient and swift, brings facility of drawing to teacher in mathematical education.
For achieving the above object, the utility model proposes kind of the special drawing teaching aid of teaching, comprise protractor, ruler, connector, screw, drawing parts, ruler is divided into left ruler, right ruler, left ruler is connected with right ruler connector, protractor is connected in the middle part of ruler by connector, and screw is installed on left ruler front end, and drawing parts are installed on right ruler front end.
As preferably, described protractor is marked with angle index.
As preferably, described ruler is marked with length scale, and left ruler and right ruler are symmetrical size, and left ruler and right ruler front end all have screwed hole.
As preferably, described connector comprises nut, bolt.
As preferably, described screw and left ruler are for being threaded, and drawing parts and right ruler are for being threaded.
As preferably, described drawing parts comprise chalk holder, chalk, and chalk clamp is loaded in chalk holder.
The beneficial effects of the utility model: the utility model is convenient and swift by making compasses, ruler, protractor be combined, bring facility of drawing to teacher in mathematical education.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is that the utility model kind is imparted knowledge to students the front view of special drawing teaching aid;
Fig. 2 is that the utility model kind is imparted knowledge to students the connector schematic diagram of special drawing teaching aid;
Fig. 3 is that the utility model kind is imparted knowledge to students each block diagram of special drawing teaching aid.
In figure: 1-protractor, 2-ruler, 3-connector, 4-screw, 5-drawing parts, the left ruler of 21-, the right ruler of 22-, 31-nut, 32-bolt, 51-chalk holder, 52-chalk.
[detailed description of the invention]
Consult Fig. 1, Fig. 2, Fig. 3, the special drawing teaching aid of a kind of mathematical education of the utility model, comprise protractor 1, ruler 2, connector 3, screw 4, drawing parts 5, ruler 2 is divided into left ruler 21, right ruler 22, left ruler 21 is connected with right ruler 22 connector 3, protractor 1 is connected in the middle part of ruler 2 by connector 3, and screw 4 is installed on left ruler 21 front end, and drawing parts 5 are installed on right ruler 22 front end.
Described protractor 1 is marked with angle index, described ruler 2 is marked with length scale, left ruler 21 is symmetrical size with right ruler 22, left ruler 21 all has screwed hole with right ruler 22 front end, described connector 3 comprises nut 31, bolt 32, and described screw 4 and left ruler 21 are for being threaded, and drawing parts 5 and right ruler 22 are for being threaded, described drawing parts 5 comprise chalk holder 51, chalk 52, and chalk 52 is clipped in chalk holder 51.
Utility model works process:
In the course of the work, protractor 1, ruler 2 can be used alone the special drawing teaching aid of a kind of mathematical education of the utility model.When using compasses, left ruler 21 is connected by connector 3 with right ruler 22, by connector 3, ruler is connected on protractor 1 again, drawn angle is changed by sliding in the chute of protractor 1, angle can intuitively read on protractor 1, after angle is determined, tighten the connector 3 between protractor 1 and ruler 2.The mode that is threaded connection by screw 4 is connected on left ruler 21, and chalk holder 51 is threaded connection mode and is connected on right ruler 22, and chalk 52 is clipped in chalk holder 51.Using screw 4 as fulcrum, left ruler 21 is rotating shaft, and chalk 52 contacts blackboard, and right ruler 22 rotates around rotating shaft, can realize the effect that circular arc drawn by compasses.
The special drawing teaching aid of a kind of mathematical education of the utility model, can make compasses, ruler, protractor be combined convenient and swift, bring facility of drawing to teacher in mathematical education.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
