Problems solved by technology

It solves the problem that the existing model display device cannot rotate teaching aids and takes up a lot of space; however, the horizontal position of the rotating disk of the device cannot be adjusted, which reduces the teaching efficiency of teachers. Therefore, we propose a mathematical model teaching aid

Abstract

The invention discloses a mathematical model teaching instrument and belongs to the technical field of teaching equipment. The problem is solved that the horizontal position of a rotating disc of an existing device is not adjustable. According to the technical scheme, the mathematical model teaching instrument is characterized by including a support base, a placement cavity and a lifting base; theupper portion of the support base is provided with the placement cavity, the middle of the lower surface of the placement cavity is fixedly connected with the lifting base, the lower end of the lifting base extends into the placement cavity, the placement cavity is slidably connected with the lifting base, a hydraulic cylinder is installed on the support base, the expansion end of the hydraulic cylinder is welded to the placement cavity, the right side of the hydraulic cylinder is equipped with a PLC, and the PLC is installed on the support base and electrically connected with the hydraulic cylinder. The operation is simple, the control is convenient, the teaching instrument is helpful to teachers' teaching, the learning efficiency of students can be improved, and the teaching instrumentis suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a mathematical model teaching aid. Background technique [0002] A mathematical model is a mathematical structure that is expressed in a general or approximate manner by using mathematical language with reference to the characteristics or quantitative dependencies of a certain system of things. Pure relational structure; in a broad sense, mathematical models include various concepts, formulas and theories in mathematics. Because they are all abstracted from the prototypes of the real world, in this sense, the whole of mathematics can also be said to be a science about mathematical models; in a narrow sense, mathematical models only refer to those that reflect specific problems or specific specific problems. In this sense, the mathematical relationship structure of a system of things can also be understood as a mathematical expression that links the relationships among...
