Embodiment 1

[0028] Embodiment 1: a math teaching board for quickly drawing function curves, comprising a display board 1, a function drawing unit 3 and an angle adjustment unit 4;

[0029] The middle rear end of the display board 1: a connecting corner block 2 is installed;

[0030] Function drawing unit 3: including a movable seat 31, a movable plate 32, a function slot plate 33, a suction cup 34 and a movable plate handle 35, a movable seat 31 is installed on the front side of the left end of the display board 1, and the right end of the movable plate 32 is connected with the movable vertical column through the movable vertical column. The movable seat 31 is rotatably connected, the function slot plate 33 is clamped in the middle of the movable plate 32, the suction cup 34 is installed on the left side of the front end of the movable plate 32, and the movable plate handle 35 is installed on the left rear end of the movable plate 32; The function slot plate 33 can draw different types of...

Embodiment 2

[0034] The difference between this embodiment and the first embodiment is that:

[0035] In this embodiment, a lifting unit 5 is also included. The lifting unit 5 includes a lifting column 51 , a column snap ring 52 and a lifting cylinder 53 . The lower end of the angle swivel base 43 is connected to the upper end of the lifting column 51 , and the column snap ring 52 is installed on the lifting column 51 . The lower end of the lifting column 51 is slidably connected to the inside of the lifting cylinder 53 . By sliding the lifting column 51 in the lifting cylinder 53 , the height of the lifting column 51 can be controlled by the column snap ring 52 .

[0036] The lifting unit 5 also includes a lock cylinder box 54 and an inner box rotating column 55 , a lock column box 54 is installed at the front end of the lifting cylinder 53 , and an inner box rotation column 55 is installed inside the lock column box 54 . The rotary column 55 in the box is fixed inside the lock column bo...

Embodiment 3

[0039] The difference between this embodiment and the first embodiment is that:

[0040] In this embodiment, a counterweight base plate 6 is also included, and the lower end of the lifting cylinder 53 is connected to the middle of the upper end of the counterweight base plate 6 . The counterweight bottom plate 6 can make the teaching board more stable.

[0041] It also includes a placing box 7 , and a placing box 7 is installed on the lower side of the right end of the display board 1 . The placing box 7 can be used to place some chalks, etc., to assist teaching.

[0042]When in use: firstly, by turning the locking column lever 56, the column snap ring 52 is clamped by the arc-shaped locking plate 57, the height of the lifting column 51 is adjusted, and then the fixed screw 41 is rotated to connect the back of the corner block 2. The left side of the end is clamped with the inner left end of the angle swivel base 43 to fix the angle of the display board 1. Finally, pull the ...

Abstract

The invention discloses a mathematics teaching board capable of rapidly drawing a function curve. The mathematics teaching board comprises a display board, a function drawing unit and an angle adjusting unit, a connecting angle block is mounted at the rear end of the middle of the display board; the function drawing unit comprises a movable seat, a movable plate, a function groove plate, a sucker and a movable plate handle, the movable seat is mounted on the front side of the left end of the display plate, the right end of the movable plate is rotatably connected with the movable seat through a movable vertical column, the function groove plate is clamped in the middle of the movable plate, and the sucker is mounted on the left side of the front end of the movable plate. The movable plate handle is mounted at the left rear end of the movable plate; according to the mathematics teaching board capable of rapidly drawing the function curve, function images can be drawn on the display board by replacing different types of function drawing boards, angle and height adjustment is more stable, and the mathematics teaching board can better meet teaching requirements in use.

Description

technical field [0001] The invention relates to the technical field of math teaching boards, in particular to a math teaching board for quickly drawing function curves. Background technique [0002] In the teaching process, the teacher needs to draw the images of some functions in mathematics teaching, and then explain to the students, the traditional display board can not better provide convenience for the drawing of function curves. [0003] Among them, a math teaching board for quickly drawing function curves proposed by the application number 201810950877.5 in the present technology includes a base, four moving wheels for moving are installed on the bottom of the base, and a storage box is fixed on the top of the base. The top of the box is provided with a sliding groove, and the sliding groove is provided with a horizontal adjustment device. The horizontal adjustment device includes a sliding block, a support plate, a threaded rod and a rotating block. The sliding block...
