The purpose of this utility model is at the deficiencies in the prior art, provides a kind of reasonable in design, simple in structure, can help the student to understand the content of courses, the mathematical education plate of improving the quality of teaching.
For addressing the above problem, the utility model by the following technical solutions:
A kind of mathematical education plate, comprise magnetic sheet, described magnetic sheet is provided with coordinate line, demonstration line, and described demonstration line is slidingly connected by magnetic piece and magnetic sheet, the mutual adhesive of described magnetic sheet and magnetic piece, the position that is positioned at coordinate line one side on the described magnetic sheet is provided with the functional value measurement mechanism.
Below be further improvement of the utility model:
Described functional value measurement mechanism comprises the protractor of fixedlying connected with magnetic sheet, be respectively equipped with scale mark on the base of described protractor and the arc limit, the middle part of described protractor is provided with scale mark, the home position of the described protractor pole that is magnetic that is rotationally connected, the middle part of described magnetic pole is provided with chute, slidely connect fastening bolt in the described chute, described fastening bolt is provided with magnetic pointer, perpendicular, the lower end of described perpendicular is fixedly connected with plummet, and described magnetic pointer can rotate along fastening bolt.
Further improve:
The bottom of described magnetic sheet is provided with electronic watch.
Further improve:
The upper end of described magnetic sheet is provided with handle.
The utility model adopts technique scheme, can help the student to learn trigonometric function, memory trigonometric function formula, has improved the interest of study, has improved quality of instruction simultaneously.
Be described further below in conjunction with the accompanying drawing the technical solution of the utility model.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Among the figure: the 1-coordinate line; 2-demonstrates line; The 3-magnetic piece; The 4-handle; The 5-magnetic sheet; The 6-protractor; 7-magnetic pole; The 8-chute; The 9-fastening bolt; The 10-perpendicular; 11-magnetic pointer; The 12-bearing pin; The 13-plummet; The 14-electronic watch.
Embodiment
Embodiment, as shown in Figure 1, a kind of mathematical education plate, the magnetic sheet 5 that comprises rectangle, the surface of described magnetic sheet 5 is provided with coordinate line 1, demonstration line 2, and described demonstration line 2 is slidingly connected by magnetic piece 3 and magnetic sheet 5, and described magnetic piece 3 can drive demonstration line 2 and slide at magnetic sheet 5, described magnetic sheet 5 and magnetic piece 3 mutual adhesives, the position that is positioned at coordinate line 1 one sides on the described magnetic sheet 5 is provided with the functional value measurement mechanism.
Described functional value measurement mechanism comprises the protractor 6 of fixedlying connected with magnetic sheet 5, be respectively equipped with scale mark on the base of described protractor 6 and the arc limit, the middle part of described protractor 6 is provided with scale mark, the home position of described protractor 6 is by bearing pin 12 pole 7 that is magnetic that is rotationally connected, the middle part of described magnetic pole 7 is provided with chute 8, described magnetic pole 7 can with magnetic sheet 5 adhesives, slidely connect fastening bolt 9 in the described chute 8, described fastening bolt 9 is provided with magnetic pointer 11, perpendicular 10, described magnetic pointer 11 can with magnetic sheet 5 adhesives, the lower end of described perpendicular 10 is fixedly connected with plummet 13, and described magnetic pointer 11 can rotate along fastening bolt 9.
The bottom of described magnetic sheet 5 is provided with electronic watch 14, can make the teacher grasp instructional blocks of time by electronic watch 14.
