Embodiment 1
[0032] Such as Figure 1-6 As shown, the embodiment of the present invention provides an angle teaching aid for university teaching, including a base 1 and a rotating shaft 2, the upper part of the base 1 is fixedly connected with the rotating shaft 2, and the end of the rotating shaft 2 away from the base 1 is fixedly connected with a light-emitting seat 3 , the top of the light-emitting seat 3 is connected with the rotating seat 4 through the rotating mechanism 9. The rotating mechanism 9 includes a rotating ring gear 901, a fixed shaft 902, a telescopic thimble 903 and an elastic reed 904. The top of the rotating ring gear 901 is connected to the rotating seat. 4 Fixed connection, the internal arc-shaped teeth of the rotating inner gear ring 901 are 360, and the outer side of the fixed shaft 902 is equidistantly fixedly connected with four telescopic thimbles 903, and the intervals between the four telescopic thimbles 903 are all fixedly connected and elastic. Reed 904, the...

The invention provides an angle teaching aid for university teaching, and relates to the field of teaching aids. The angle teaching aid based on university teaching comprises a base and a rotating shaft, wherein the rotating shaft is fixedly connected to the upper portion of the base; a light-emitting base is fixedly connected to the end, away from the base, of the rotating shaft; a rotating base is rotationally connected to the upper portion of the light-emitting base through a rotating mechanism; tangent circle cursor emitters are fixedly connected to the two sides of the rotating base correspondingly; and shafting cursor emitters are fixedly connected to the quartering positions of the lower portion of the light-emitting base correspondingly. According to the laser refraction principle, four shafting cursor emitters form a basic coordinate axis; two concentric circles with a radius difference being one time are generated by a round cursor emitting base, an inscribed circle with a radius being one fourth is generated by the tangent circle cursor emitters, and the tangent line and the circle center of the inscribed circle are utilized to draw most special angles; and lines required to be drawn by a teacher are simplified, so students can be better helped to understand the relationship between the circle and the angle.
Description
technical field [0001] The invention relates to the technical field of teaching aids, in particular to an angle teaching aid for university teaching. Background technique [0002] Teaching aids refer to models, real objects, specimens, instruments, charts, slides, etc. used to explain something, including teaching equipment, teaching instruments, training equipment, educational equipment, experimental equipment, teaching specimens, teaching models, etc. It is an object for the purpose of disseminating science and technology and educating people. It is a complete science and technology media and an indispensable equipment for young people's science and technology activities. The teaching aids used in scientific and technological activities include physical teaching aids and replica teaching aids. Specifically, there are specimens or samples from nature: such as biological specimens, mineral specimens, fossils, rocks and rare animal samples used in scientific and technologica...
