Problems solved by technology

[0005] However, the device has a large volume, and the measuring ruler is a telescopic measuring ruler. The length of the measuring ruler is mainly extended by extending the extension rod to achieve the effect of adjusting the length of the measuring ruler. Since the width of the extension rod is smaller than the width of the measuring ruler, the When drawing to the connection between the extension rod and the rotary ruler, the side wall of the extension rod and the side wall of the rotary ruler are not on a horizontal plane, so a longer straight line cannot be drawn on the blackboard. In addition, the length of the measuring ruler Depending on the length of the extension rod and the ruler, if the length of the ruler is longer, it will affect the overall volume of the multifunctional teaching aid. If the length of the ruler is shorter, the length of the measuring ruler is relatively short, which is very inconvenient convenient

Embodiment 1

[0038] by Figure 1 - Figure 8 It is given, an arcuate plate 101 mounted on the straight plate 102 is provided in the arcuate plate 101, a curved plate 101 mounted on the straight plate 102, and an arcuate plate 101, a curved plate 101, a curved plate 101, a curved plate 101, and a straight plate 101. The measuring ruler 2 is connected to the rotating shaft 18, and the length scale line 6 is provided on the measuring ruler 2, where:

[0039] The measuring ruler 2 includes a straight-scale A201, a straight-scale B202, and a straight-scale C203. Both ends of the four ends of the fastener B 204 are connected to the straight-edge A201 and the ruler C203, and the ruler A201 is close to one end of the ruler B202, the ruler Both ends of the B202 and the straightmost C203 are provided with one end of the straight-edge B202, and the mounting groove corresponding to the rotating connector 204 is provided;

[0040] The slider 7 is mounted on one side of the measuring ruler 2, and the sidewall...

Embodiment 2

[0056] On the basis of the first embodiment, the top of the straight-foot A201 is provided with a groove 14, and the inner side wall of the recess 14 is slidably connected to the moving block 16, and the moving block 16 is connected to the side wall of the recess 14, and the moving block 16 is connected by the spring B15. The side walls of the measuring ruler 2 are provided with a plurality of limit slots corresponding to the limit block 17, by the limit block 17 and the side wall of the measuring ruler 2, and a plurality of limit slots corresponding to the limit block 17, a plurality of limit slots are equidina settings.

[0057] The moving block 16 is pushed through the spring B15 to insert the limit slot on the measurement ruler 2, and the position of the slider 7 is limited, and the slider 7 is on the measuring ruler 2 during the drawing of the circle. Movement, improved the accuracy of the painting circle, while reducing the difficulty of painting a circle in the process of m...

Abstract

The invention discloses a multifunctional teaching aid for teaching, and relates to the technical field of math teaching aids. The multifunctional teaching aid comprises an angle ruler, wherein the angle ruler comprises a straight plate and an arc-shaped plate mounted on one side of the straight plate, angle scale marks are arranged on the arc-shaped plate, a measuring ruler is connected to the straight plate through a rotating shaft, and length scale marks are arranged on the measuring ruler. According to the teaching aid, the measuring ruler is mainly composed of a ruler a, a ruler b and a ruler c, and the three rulers are the same in width, so that the problem that a long straight line cannot be drawn on a blackboard is solved. The measuring ruler is mainly composed of the ruler a, the ruler b and the ruler c, the length of the measuring ruler is short before assembly, the length of the measuring ruler assembled by the three rulers is equal to the sum of the length of the ruler a, the length of the ruler b and the length of the ruler c, the length of the measuring ruler after assembly is long, the length of the measuring ruler before assembly cannot affect the size of the multifunctional teaching aid, and the problem that a measuring ruler is long and inconvenient to carry is solved.

Description

Technical field [0001] The present invention relates to the technical field of mathematical teaching, and in particular to a teaching multifunctional teaching. Background technique [0002] The teaching aid is a general title to the use of various types of appliances and teachers used by the students in an intuitive, image-like understanding of the various types of equipment used by the teaching content. Teaching Tools can improve students 'interest in learning, enriching sensual understanding, helping to form a clear concept, develop students' observations and thinking skills. [0003] In mathematics learning practice, compass, straight ruler, triangular plate, and angleometers are used almost every day. These kinds of teaching aids not only take up space, not easy to carry, and the teacher uses it is very inconvenient, and occasionally there will be a round-tip or triangular pointer to hurt people. [0004] Afterwards, China Patent Authorization Number is CN211280429U, which di...
