Problems solved by technology

[0003] However, the existing general rotating demonstration device for mathematics teaching can only perform simple rotation, and cannot rotate and height-adjust the demonstration board separately during the process of rotating the demonstration board at the same time. Leading to the lowest learning efficiency and relatively large use limitations, it brings great inconvenience to users

Embodiment

[0022] see Figure 1-3 , the present invention provides the following technical solutions: a rotating demonstration device for mathematics teaching, comprising a background board 1, a chute 2 and a groove 14 are provided on the front side of the background board 1, and a motor 15 is fixedly connected to the bottom of the inner wall of the groove 14. By setting Motor 15, motor 15 work, the output shaft of motor 15 can drive threaded column 13 to rotate, thereby can drive threaded sleeve 12 to move up and down, and then realize the purpose of adjusting the height of triangular demonstration board 24, convenient for students to observe and understand.

[0023] The output shaft of the motor 15 is fixedly connected with a threaded column 13, the top of the threaded column 13 is fixedly connected with a first rotating shaft 11, the surface of the first rotating shaft 11 is sleeved with a first bearing 10, and the first bearing 10 is fixedly connected on the inner wall of the groove 1...

Abstract

The invention belongs to the technical field of mathematics demonstration, and particularly relates to a rotary demonstration device for mathematics teaching. The device comprises a background plate,a chute and a groove are formed in the front side of the background plate, a motor is fixedly connected to the bottom of the inner wall of the groove, a threaded column is fixedly connected to an output shaft of the motor, and a first rotating shaft is fixedly connected to the top end of the threaded column. The surface of the first rotating shaft is sleeved with a first bearing, the first bearingis fixedly connected to the top of the inner wall of the groove, the surface of the threaded column is in threaded connection with a threaded sleeve, a sliding block is slidably connected into the chute, connecting rods are fixedly connected to the right side of the threaded sleeve and the left side of the sliding block, and fixing rods are fixedly connected to the bottoms of the connecting rods.According to the rotary demonstration device for mathematics teaching, the motor is arranged, the motor works, the output shaft of the motor can drive the threaded column to rotate, so that the threaded sleeve can be driven to move up and down, the purpose of adjusting the height of the triangular demonstration board is achieved, and students can observe and understand conveniently.

Description

technical field [0001] The invention belongs to the technical field of mathematics demonstration, in particular to a rotating demonstration device for mathematics teaching. Background technique [0002] Mathematics is a subject that studies concepts such as quantity, structure, change, space, and information. Observation of the shape and motion of objects. Mathematics has become a part of education in many countries and regions. It is applied in different fields, including science, engineering, medicine, economics and finance. Mathematicians also study pure mathematics. , is the substantive content of mathematics itself, without aiming at any practical application. [0003] However, the existing general rotating demonstration device for mathematics teaching can only perform simple rotation, and cannot rotate and height-adjust the demonstration board separately during the process of rotating the demonstration board at the same time. As a result, the learning efficiency is l...
