Abstract
Mathmatical ruler disclosed by the invention, including main scale and slide calliper rule, main scale include ruler and the protractor being arranged on the downside of ruler, and the zero mark end of slide calliper rule is flexibly connected on ruler, and equidistantly draw-in groove is provided with slide calliper rule.Simple structure of the present invention, it is easy to use, the efficiency and precision mapped in high school mathematics teaching activity are drastically increased, merging for chi and compasses is realized, facilitate for education activities are provided.
Description
Technical field
The present invention relates to a kind of high school mathematics teaching apparatus, particularly a kind of mathmatical ruler.
Background technology
Math teacher is when teaching is given lessons; particularly when geometry and its related discipline is taught; the various aids including ruler, set square, protractor and compasses etc. would generally be used; these instruments are all separate; and unitary function; need continually to exchange when in use, carry using inconvenience, greatly have impact on drawing efficiency.
The content of the invention
Mathmatical ruler disclosed by the invention, simple structure is easy to use, realizes the multifunction of high school mathematics teaching chi and integrated, is drawn so as to facilitate teaching, improves drawing efficiency.
Mathmatical ruler disclosed by the invention, including main scale and slide calliper rule, the main scale include ruler and the protractor being arranged on the downside of ruler, and the zero mark end of the slide calliper rule is flexibly connected on ruler, and equidistantly draw-in groove is provided with the slide calliper rule.Simple structure of the present invention, it is easy to use, quality connection is firm, it is easy to enter in maths teaching activities the drafting and demonstration of arc, the circle of line, angle, Along ent, bisector and special diameter etc., without frequently replacing different drawing tools, the difficulty of drawing performance is reduced, drastically increase the efficiency and precision mapped in high school mathematics teaching activity, realize merging for chi and compasses, for education activities provide it is convenient.
A kind of improvement of mathmatical ruler disclosed by the invention, the protractor is arranged on zero degree line and ruler the downside end face of one end of ruler and protractor on same straight line.This improvement by set protractor zero graduation line and ruler downside end face on the same line, to school high precision, be conducive to improving the precision and efficiency of camber line picture operation.
Another improvement of mathmatical ruler disclosed by the invention, the zero mark end of the slide calliper rule is movably fixed to the other end of ruler.This improvement not only contributes to simplify the structure of multipurpose ruler by the way that the zero mark end of slide calliper rule to be movably arranged on the other end of ruler, reduces production cost, while also facilitate making picture circular arc, improves the precision and efficiency of picture operation.
Mathmatical ruler disclosed by the invention, simple structure, it is easy to use, by the ruler, protractor and the slide calliper rule that set, realize the efficient accurate Drawing of the mathematical education regular pattern shape such as arc, circle of straight line, angle, Along ent, bisector and special diameter, the frequent replacement in education activities between various teaching apparatus is avoided simultaneously, so as to improve the convenience of education activities.
Brief description of the drawings
The structural representation of Fig. 1, mathmatical ruler disclosed by the invention.
Reference numerals list：
1st, ruler；
2nd, protractor；
3rd, slide calliper rule；
4th, draw-in groove.
Specific embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated, it should be understood that following specific embodiments are only illustrative of the invention and is not intended to limit the scope of the invention.It should be noted that the direction that the word "front", "rear" for being used in description below, "left", "right", "up" and "down" are referred in accompanying drawing, word " interior " and " outward " are referred respectively to towards or away from the direction of particular elements geometric center.
As shown in figure 1, mathmatical ruler disclosed by the invention, including main scale and slide calliper rule 3, the main scale includes ruler 1 and is arranged on the protractor 2 of the downside of ruler 1, and the zero mark end of the slide calliper rule 3 is flexibly connected on ruler 1, and equidistantly draw-in groove 4 is provided with the slide calliper rule 3.Simple structure of the present invention, it is easy to use, quality connection is firm, it is easy to enter in maths teaching activities the drafting and demonstration of arc, the circle of line, angle, Along ent, bisector and special diameter etc., without frequently replacing different drawing tools, the difficulty of drawing performance is reduced, drastically increase the efficiency and precision mapped in high school mathematics teaching activity, realize merging for chi and compasses, for education activities provide it is convenient.
As it is a kind of preferably, the protractor 2 is arranged on the zero degree line and the downside end face of ruler 1 of one end of ruler 1 and protractor 2 on same straight line.By set protractor zero graduation line and ruler downside end face on the same line, to school high precision, be conducive to improving the precision and efficiency of camber line picture operation.
As one kind preferably, the zero mark end of the slide calliper rule 3 is movably fixed to the other end of ruler 1.By the way that the zero mark end of slide calliper rule to be movably arranged on the other end of ruler, not only contribute to simplify the structure of multipurpose ruler, reduce production cost, while also facilitate making picture circular arc, improve the precision and efficiency of picture operation.
Mathmatical ruler disclosed by the invention, simple structure, it is easy to use, by the ruler, protractor and the slide calliper rule that set, realize the efficient accurate Drawing of the mathematical education regular pattern shape such as arc, circle of straight line, angle, Along ent, bisector and special diameter, the frequent replacement in education activities between various teaching apparatus is avoided simultaneously, so as to improve the convenience of education activities.
Technological means disclosed in the present invention program is not limited only to the technological means disclosed in above-mentioned technological means, also including being combined constituted technical scheme by above technical characteristic.The above is specific embodiment of the invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; some improvements and modifications can also be made, these improvements and modifications are also considered as protection scope of the present invention.
