Abstract

The utility model discloses a teaching board for advanced mathematics, which comprises a vertical board, a base and a plurality of transparent frosted glass plates. A crossbeam is arranged at the top of the vertical board, grid layers are adhered to the front face and the back face of the vertical board respectively, hanging rods are symmetrically arranged on two side walls of the crossbeam, hanging rings are arranged on the frosted glass plates, the side walls of each frosted glass plate is peripherally wrapped by a protective cover, and the frosted glass plates are hung on the front face and the back face of the vertical board respectively and attached to the grid layers. The teaching board for advanced mathematics is simple in structure and convenient in use, drawing is effectively standardized, and teaching quality is improved. Further, the front face and the back face of the teaching board are reusable, drawing accuracy can be improved by the aid of the grid layers, and time is greatly saved.

Description

The Higher Mathematics Teaching plate

Technical field

The utility model relates to mathematics teaching aid, relates in particular to a kind of Higher Mathematics Teaching plate.

Background technology

In Teaching in University, often need on blackboard, draw some figures, curve etc.Owing to do not have coordinate, grid on the existing blackboard; Increased the difficulty that the teacher draws, and the bigger error of the figure of drawing existence, cause the shape of function curve inaccuracy, figure inaccurate; The visual experience that can interfere with one's studies further causes teaching efficiency relatively poor.

Summary of the invention

To the problem that above-mentioned prior art exists, the utility model provides a kind of Higher Mathematics Teaching plate.

To achieve these goals, the technical scheme of the utility model employing is: a kind of Higher Mathematics Teaching plate comprises riser and base; Also comprise the focussing glass that several piece is transparent, the top of riser is provided with crossbeam, and the front and back of riser all is pasted with clathrum; The two side of crossbeam is arranged with peg respectively; Focussing glass is provided with link, and sidewall is coated with protective sleeve around the focussing glass, and focussing glass hangs up respectively in the front and back of riser and with clathrum and fits.

As preferably, peg is two groups.

As preferably, all mate link and peg shape size position.

Compared with prior art, the advantage of the utility model is: simple in structure, easy to use, effectively standard the standard of drawing; Improved quality of instruction; Can repeatedly use by positive and negative simultaneously, clathrum can improve the drawing degree of accuracy, has saved the time greatly.

The specific embodiment

To combine accompanying drawing that the utility model is described further below.

As a kind of embodiment of the utility model, consult Fig. 1 and Fig. 2, the utility model comprises riser 1 and base 2; Also comprise the transparent focussing glass of several piece 51, the top of riser 1 is provided with crossbeam 31, and the front and back of riser 1 all is pasted with clathrum 4; The two side of crossbeam 31 is arranged with peg 32 respectively; Focussing glass 51 is provided with link 52, and sidewall is coated with protective sleeve 53 around the focussing glass 51, and focussing glass 51 hangs up respectively in the front and back of riser and with clathrum 4 and fits.Peg 32 is two groups.Link 52 all matees with peg 32 shapes size position.

The utility model is simple in structure, easy to use; Effectively standard the standard of drawing, improved quality of instruction, can repeatedly use by positive and negative simultaneously; Clathrum 4 can improve the drawing degree of accuracy; Saved the time greatly, sidewall is coated with protective sleeve 53 around the focussing glass 51, and protective hair glass plate 51 is not broken.

To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation in spirit that does not break away from the utility model or the scope in other embodiments among this paper.Therefore, the utility model will can not be limited to these embodiment shown in this paper, but will accord with principle disclosed herein and features of novelty the wideest corresponding to scope.
