Mathematics teaching board capable of performing deformation and expansion and mounting method thereof

Abstract

The invention discloses a mathematics teaching board capable of performing deformation and expansion and a mounting method thereof. The mathematics teaching board includes a board body, a fixed rod, amounting frame, a pressing block, a supporting rod, a supporting sleeve, a fixed base, a stabilizing rod, a placing frame, a lighting lamp, a fixing button, a spring, a drawing ruler, rubber legs, acoordinate system diagram, a geometric figure, a magnet, a clamping opening and a magnetic block. The mathematics teaching board has the advantages that the fixed rod can freely rotate in the mountingframe and is fixed in a mode of screwing through the pressing block, the switching between a front surface and the rear surface of the teaching board can be performed very conveniently, so that the teaching board does not occupy space and can increase a writing area, the supporting rod can move up and down in the supporting sleeve and is fixed through the fixing button and the spring, such as design enables the height of the board body to be freely adjusted, the supporting sleeve, the fixed base and the stabilizing rod are in triangular connection, so that the stabilizing rod supports the supporting sleeve more stably, and the supporting sleeve is protected from damage when subjected to stress.

Description

technical field [0001] The invention relates to a mathematics teaching board, in particular to a deformable and telescopic mathematics teaching board and an installation method thereof, belonging to the field of teaching equipment. Background technique [0002] The teaching board is a tool used for writing demonstrations in the education industry. It plays a very important role in teaching. It is frequently used in the teaching of mathematics, Chinese and other subjects. In the teaching of mathematics, it is often necessary to draw on the teaching board. Various graphics and coordinate systems. [0003] It is very troublesome to temporarily draw graphics on the teaching board. The time is tight and not very accurate. The hasty drawing will affect the learning progress and teaching quality, and it is difficult to express accurately. Moreover, when drawing, the teacher needs to hold the drawing ruler high with one hand and hold the chalk in the other hand. As shown in the fig...

Problems solved by technology

[0003] It is very troublesome to temporarily draw graphics on the teaching board. The time is tight and not very accurate. The hasty drawing will affect the learning progress and teaching quality, and it is difficult to express accurately. Moreover, when drawing, the teacher needs to hold the drawing ruler high with one hand and hold the chalk in the other hand. As shown in the figure, this operation is very troublesome, time-consuming and laborious, and increases the difficulty of work for teachers. It is composed of a writing board. The teaching board with a large area is too large and inconvenient to place. The writing area of ​​a small teaching board is too small to be able to It meets the requirements of both drawing and writing in mathematics teaching, and when the existing teaching board is illuminated by a light source on one side, the light source is not uniform, resulting in reflections on the surface of the teaching board, making students unable to see the teaching board clearly and affecting learning Effect
