Detailed Description

In order to more clearly and completely explain the technical scheme of the present invention, the present invention is further explained with reference to the attached drawings.

Referring to fig. 1 to 3, the present invention provides an activity protractor, which includes a protractor plate 1, a ruler plate 2 and a fixing bolt 3, wherein the protractor plate 1 is provided with an arc edge 10, a first scale mark 4, a first color bar 5, a second color bar 6 and a positioning hole 9, the ruler plate 2 is provided with a third color bar 12, a fourth color bar 13 and a connecting hole 14, the fixing bolt 3 penetrates through the connecting hole 14 and the positioning hole 9, so that the protractor plate 1 and the ruler plate 2 form a movable connection, the first scale mark 4 is disposed on the arc edge 10, the first color bar 5 is attached to the first scale mark 4, the second color bar 6 is attached to the first color bar 5, and the third color bar 12 and the fourth color bar 13 are joined and disposed on the same straight line; the first color bar 5 and the third color bar 12 are the same color; the second color bar 6 and the fourth color bar 13 are the same in color; the ruler plate 2 is provided with second scale marks 11, and the second scale marks 11 are arranged on the edge of the ruler plate 2; the first color bar 5 is provided with a first mark 7, the second color bar 6 is provided with a second mark 8, and the first mark 7 and the second mark 8 are used for adjusting the ruler plate 2; the first mark 7 and the second mark 8 are angle marks, the angle mark of the first mark 7 is clockwise mark from small to large, and the angle mark of the second mark 8 is counterclockwise mark from small to large.

In this embodiment, the ruler plate 2 is made of transparent material, the user can see the angle measuring plate 1 through the ruler plate 2, the fixing bolt 3 mounts the angle measuring plate 1 and the ruler plate 2 to form a movable connection, the ruler plate 2 can rotate relative to the angle measuring plate 1 along the fixing bolt 3, so that the ruler plate 2 can sweep clockwise or counterclockwise on the angle measuring plate 1, the first color bar 5 and the second color bar 6 are different in color, when the ruler plate 2 sweeps the angle measuring plate 1 clockwise, the third color bar 12 also sweeps the angle measuring plate 1, since the first color bar 5 and the third color bar 12 are the same in color, the intersection of the first color bar 5 and the third color bar 12 can be visually and clearly seen, and the position of the ruler at this time can be determined by the first scale, when the straight ruler plate 2 sweeps across the angle measuring plate 1 anticlockwise by reading through the first mark 7, the fourth color bar 13 sweeps across the angle measuring plate 1 at the moment, the second color bar 6 and the fourth color bar 13 are the same in color, so that the intersection of the second color bar 6 and the fourth color bar 13 can be seen visually and clearly, the position of the straight ruler at the moment is determined through the first scale, when the second mark 8 reads, the first mark 7 and the second mark 8 are angle marks along with the change of the angle formed by clockwise or anticlockwise rotation of the straight ruler plate 2, the first mark 7 is clockwise from 0 degree to 180 degrees, the second mark 8 is anticlockwise from 0 degree to 180 degrees, a teacher can measure angles in different directions by rotating the straight ruler plate 2, when the degree of the angle needs to be measured, the angle measuring plate 1 is determined firstly, readjust straight ruler board 2 makes the student can directly judge be in it is third colour bar 12 or fourth colour bar 13 that angulometer board 1 pivoted, again correspond first colour bar 5 or second colour bar 6 carry out the reading, can help the teacher to teach, make the student can more audio-visual see out, the colour bar of the same colour removes the angle transformation that produces, becomes the obtuse angle again from the acute angle, does benefit to the knowledge content of the comprehensive vivid understanding angle of student, the student also can manual operation, effectively help the teaching of teacher and the quick understanding of student and the relevant knowledge point of memory.

In this embodiment, the activity protractor not only can regard as the teaching aid that mr's teaching show was used, can also regard as the learning aid that the student studied, and mr can adjust the study with the student in the classroom in step, and the change of angle effectively helps mr's teaching and the quick understanding of student and the relevant knowledge point of memory, also can improve student's hands-on ability.

Of course, the present invention can also have other various embodiments, and based on the embodiments, those skilled in the art can obtain other embodiments without any creative work, and all of them belong to the protection scope of the present invention.
