Combined teaching aid for teaching measurement

Abstract

The present invention discloses a combined teaching aid for teaching measurement. The combined teaching aid comprises a support pedestal and a rotary seat, the rotary seat is connected with the support pedestal through a rotation column, combined measurement mechanisms are installed at two sides of the support pedestal, each combined measurement mechanism comprises measurement tables installed attwo sides of the support pedestal, the two ends of each measurement table are connected with spring columns, the outer end of each spring column is connected with one measurement seat, each measurement seat is internally provided with two measurement reels, each measurement reel is fixed at the internal portion of the support pedestal through one metal shaft, the outer side of each measurement seat is provided with one measurement outlet, each measurement outlet is internally provided with one spring clamp, one measurement flexible rule is winded at the surface of each measurement reel, the tail end of each measurement flexible rule is connected with one magnetic base, and the surface of each magnetic base is provided with one metal pad. The action of the combined measurement mechanisms 8is employed to measure the external devices and rapidly measure objects with different shapes and sizes so as to meet different measurement demands, and the combined teaching aid is more practical when being concretely used.

Description

technical field [0001] The invention relates to the technical field of teaching aids, in particular to a combined teaching aid for teaching measurement. Background technique [0002] Teaching aids are teaching aids, which are the general term for all kinds of utensils used by students to intuitively and visually understand the teaching content and the utensils used by teachers in teaching. Teaching aids can improve students' learning interest, enrich perceptual knowledge, and help form clear concepts. Develop students' observation and thinking skills. It is generally divided into three categories: ordinary teaching aids, special teaching aids, and children's teaching aids. [0003] Ordinary teaching aids: including conventional and professional teaching aids used in basic education in primary and secondary schools and various professional education in colleges and technical secondary schools. Generally, there are real objects, which directly present objective things in fron...

AI Technical Summary

Problems solved by technology

[0008] (1) General teaching aids can only be used for single-function writing and display, which cannot meet different teaching needs;

[0009] (2) At the same time, when using teaching aids, since most of them still use chalk to write, more dust will inevitably be produced when writing and wiping, which seriously affects the health of teachers;

[0010] (3) Moreover, the general teaching aids adopt a fixed structure when used, not only cannot be moved, but also cannot be adjusted. When performing a demonstration, there is a lack of intuitive contrast and a good demonstration effect cannot be achieved, and traditional teaching aids can only achieve Face-to-face demonstrations cannot be shared remotely, which greatly limits the use of teaching aids
