Straightedge device for mathematics teaching

Abstract

The invention provides a straightedge device for mathematics teaching. The straightedge device for mathematics teaching comprises a first dividing ruler, a first rotating shaft is hinged to one side of the bottom of the first dividing ruler, a second dividing ruler is hinged to one side of the first rotating shaft, and an inverted hook is fixedly connected to one side of the first dividing ruler.A hinging connecting piece is fixedly installed on one side of the second dividing ruler, a connecting pipe is hinged to one side of the hinging connecting piece, a through groove is formed in the connecting pipe, and a connecting spring is fixedly installed at the bottom of an inner cavity of the through groove. A connecting block is fixedly connected to one end of the connecting spring, a connecting rod is welded to one side of the connecting block, one end of the connecting rod extends to the outer surface of the connecting pipe and is welded with a buckling ring, and the inner side of thebuckling ring is buckled with the outer surface of the inverted hook. According to the straightedge device for mathematics teaching, by arranging the first dividing ruler, the first rotating shaft andthe second dividing ruler, the length of the straightedge can be increased, so that a teacher does not need to move the straightedge repeatedly when drawing long lines, and the drawing operation of the teacher is facilitated.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a ruler equipment for mathematics teaching. Background technique [0002] Straightedge is widely used in mathematics, surveying, engineering and other disciplines. It is a ruler-shaped gauge with precise straight edge. Straightedge is used for straightness measurement and flatness measurement by light gap method. It can also be used together with gauge blocks for inspection length dimension. [0003] Mathematics is a discipline that studies concepts such as quantity, structure, change, space, and information. From a certain perspective, it belongs to a kind of formal science. Mathematicians and philosophers have a series of views on the exact scope and definition of mathematics, while In the development of human history and social life, mathematics also plays an irreplaceable role, and it is also an indispensable basic tool for learning and researching modern science ...

[0003] Mathematics is a discipline that studies concepts such as quantity, structure, change, space, and information. From a certain perspective, it belongs to a kind of formal science. Mathematicians and philosophers have a series of views on the exact scope and definition of mathematics, while In the development of human history and social life, mathematics also plays an irreplaceable role, and it is also an indispensable basic tool for learning and researching modern science and technology; in mathematics, teachers often need to use a ruler on the blackboard when teaching drawing, but the existing ruler design is relatively simple, and the function is relatively single, so that it cannot meet people's needs
