Abstract
The utility model relates to a multi-functional ruler for university mathematics. The existing various rulers used in mathematic classes exist independently and include many categories such as triangular rulers, straight rulers, graphometers and compasses. During class, students have to take all rulers to finish learnt content. The multi-functional ruler for the university mathematics comprises a straight ruler body. A hexagon (2), an isosceles trapezoid (3) and a parallelogram (4) are arranged in the straight ruler body (1) sequentially, one side of the straight ruler body is connected with a graphometer (5), the graphometer is connected with a compass, and the straight ruler body is connected with a 30-degree right-angle triangular ruler (6) and a 45-degree right-angle triangular ruler (7). The multi-functional ruler is suitable for teaching and study of the university mathematics.
Description
Technical field
the utility model relates to a kind of College Maths multifunctional ruler.
Background technology
the various chis that mathematics class is used now are individualisms, and kind much has set square, ruler, graphometer, compasses etc., in the time of at school, need to all bring all chis and can complete learned content.Both bothered, the student who also has often leaves behind such or such chi, and impact study, also affect teachers, very unfavorable for study.Also must be with complete needed various chis, trouble very during teachers.
Summary of the invention
the purpose of this utility model is to provide a kind of various chis that integrate, and can complete the College Maths multifunctional ruler of the task that all chis need to complete.
above-mentioned purpose realizes by following technical scheme:
a kind of College Maths multifunctional ruler, its composition comprises: the ruler body, have in turn hexagon, isosceles trapezoid, parallelogram in described ruler body, described ruler body one side connects graphometer, described graphometer connects compasses, and described ruler body connects 30 ° of drawing squares and 45 ° of drawing squares.
described College Maths multifunctional ruler, described compasses comprise straight-bar, described straight-bar connects extension bar, described straight-bar and described extension bar all have one group of concentric holes, described straight-bar is connected by described concentric holes with described extension bar, the described extension bar other end connects the pen cap, and the described straight-bar other end connects the center of circle of described graphometer.
described College Maths multifunctional ruler, stretch between described straight-bar and described extension bar or shorten.
described College Maths multifunctional ruler, described ruler body is rectangle or square, and described rectangle or described foursquare two right-angle sides have rule, and described graphometer has bevel protractor.
described College Maths multifunctional ruler, described ruler body is inlaid with magnetic sheet in the position of described 30 ° of drawing squares, described 45 ° of drawing squares, described 30 ° of drawing squares and described 45 ° of drawing squares are inlaid with magnetic sheet, between described ruler body and described 30 ° of drawing squares and described 45 ° of drawing squares by described magnetic sheet adhesive.
beneficial effect:
1. the utility model rolls into one various chis, multiple functional, and purposes is many, can complete the task of all chis.
2. the utility model can either draw the circle of various sizes, also can draw the triangle of hexagon, isosceles trapezoid, parallelogram, various angles.
3. the utility model adopts 30 ° of drawing squares, 45 ° of drawing squares can very easily draw 30 ° of right angled triangles and 45 ° of right angled triangles commonly used, and the technique of painting directly, simply.
4. straight-bar of the present utility model and extension bar can draw the circle of arbitrary diameter, extensively more a lot of than the purposes of existing compasses, and not only study can be used, and Graphing of Engineering also can be used.
the accompanying drawing explanation:
accompanying drawing 1 is the structural representation of this product.
the specific embodiment:
