Abstract

The invention discloses a cycloid demonstration teaching aid for advanced mathematics teaching and a using method thereof, and the cycloid demonstration teaching aid comprises a Y ruler, an X ruler, laser lamps, lenses, a lamp switch and a rotating shaft, wherein one end of the Y ruler is connected with one end of the X ruler at 90 degrees, the Y ruler and the X ruler are uniformly provided with the laser lamps, the front ends of the laser lamps are provided with the lenses, the rear ends of the laser lamps are provided with the rotating shaft, the laser lamps are rotationally connected with the Y ruler or the X ruler through the rotating shaft, and the lamp switch is arranged on the laser lamps. Compared with the prior art, the laser lamp can transmit a plurality of straight lines, oblique lines and cross lines on the blackboard at will, the angle of each line can be adjusted at will, teaching of advanced mathematics is facilitated, drawing time is saved, teaching efficiency is improved, and the laser lamp has popularization and application values.

Description

Cycloid demonstration teaching aid for advanced math teaching and use method

Technical Field

The invention relates to teaching auxiliary equipment, in particular to a cycloid demonstration teaching aid for advanced math teaching and a using method thereof.

Background

Higher mathematics means that objects and methods of mathematics are a relatively complex part of the first mathematics. In a broad sense, mathematics other than elementary mathematics are higher mathematics, and algebra, geometry and simple set theory elementary and logic elementary which are deeper in middle school are also called intermediate mathematics, and are used as the transition between elementary mathematics in the middle and primary schools and higher mathematics in the university. Among the prior art, when higher mathematics teaching, mostly need draw straight line, cross line, slash etc. on the blackboard, and the size is drawn through measurement back such as set-square, ruler, bevel protractor mostly, and is comparatively loaded down with trivial details, and inefficiency lengthens the teaching time, consequently, exists and improves the space.

Disclosure of Invention

The invention aims to solve the problems and provide a cycloid demonstration teaching aid for advanced mathematics teaching and a using method thereof.

The invention realizes the purpose through the following technical scheme:

the cycloid demonstration teaching aid for higher mathematics teaching comprises a Y ruler, an X ruler, laser lamps, lenses, a lamp switch and a rotating shaft, wherein one end of the Y ruler is connected with one end of the X ruler at 90 degrees, the Y ruler and the X ruler are uniformly provided with the laser lamps, the lenses are arranged at the front ends of the laser lamps, the rotating shaft is arranged at the rear ends of the laser lamps, the laser lamps are rotatably connected with the Y ruler or the X ruler through the rotating shaft, and the lamp switch is arranged on the laser lamps.

Further, the rear end of the lamp switch is also provided with a pointer, and an angle graduated scale used for displaying the rotation angle of the laser lamp is arranged below the pointer on the Y ruler or the X ruler.

The invention has the beneficial effects that:

compared with the prior art, the cycloid demonstration teaching aid for advanced mathematics teaching and the use method thereof can transmit a plurality of straight lines, oblique lines and cross lines on a blackboard through the laser lamp at will, and the angle of each line can be adjusted at will, so that the cycloid demonstration teaching aid is convenient for advanced mathematics teaching, saves drawing time, improves teaching efficiency and has popularization and application values.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a partially enlarged view of a portion a in fig. 1.

In the figure: 1-blackboard, 2-Y ruler, 3-X ruler, 4-laser lamp, 5-lens, 6-lamp switch, 7-rotating shaft, 8-pointer, 9-angle scale.

Detailed Description

The invention will be further described with reference to the accompanying drawings in which:

as shown in fig. 1 and 2: the cycloid demonstration teaching aid for higher mathematics teaching comprises a Y ruler 2, an X ruler 3, a laser lamp 4, a lens 5, a lamp switch 6 and a rotating shaft 7, wherein one end of the Y ruler is connected with one end of the X ruler at 90 degrees, a plurality of laser lamps are uniformly arranged on the Y ruler and the X ruler, the lens is arranged at the front end of the laser lamp, the rotating shaft is arranged at the rear end of the laser lamp, the laser lamp is rotatably connected with the Y ruler or the X ruler through the rotating shaft, and the lamp switch is arranged on the laser lamp.

Further, the rear end of the lamp switch is also provided with a pointer 8, and an angle graduated scale 9 used for displaying the rotation angle of the laser lamp is arranged below the pointer on the Y ruler or the X ruler.

The invention discloses a use method of a cycloid demonstration teaching aid for advanced math teaching, which comprises the following steps:

when the laser blackboard is used, the Y ruler and the X ruler are attached to the lower left corner of the blackboard 1, the magnet or the gum can be arranged on the back of the Y ruler or the X ruler for attachment, one or more laser lamps are turned on when the cycloid curve on the blackboard is needed, the laser lamps project light rays into straight lines through the lenses, projection lines can be displayed on the blackboard, the angle of a single laser lamp can be adjusted, oblique lines can be projected on the blackboard, the lines projected by the Y ruler and the X ruler at the same time can be crossed, and the laser blackboard is convenient and practical.

The foregoing shows and describes the general principles and features of the present invention, together with the advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
