[0028] like Figure 1 to Figure 5As shown, the present embodiment proposes a display board for education and teaching, including a support plate 1, a connecting seat 22 and a base 5, a plurality of symmetrically arranged fixing frames 2 are welded inside the support plate 1, and a plurality of fixing frames 2 are fixedly connected to a display stand 3 together, a lifting rack column 19 is slidably mounted inside the base 5, and the lifting rack column 19 is welded together to the bottom of the connecting seat 22, and a limiting block 20 is fixedly connected to the bottom of the lifting rack column 19, a toggle block 13 and a pressing block 14 are respectively provided on one side of the base 5, a driving shaft 11 and a driven shaft 18 are rotatably installed inside the base 5, a driving gear 15, a ratchet 12 and a turning handle 10 are respectively fixedly sleeved on the outer circumference of the driving shaft 11, a handle 9 is welded on one side of the turning handle 10, and a driven shaft 18 is A driven gear 16 and a lifting gear 17 are fixedly sleeved on the outer circumferential surface respectively, the driving gear 15 and the driven rotating shaft 18 are rotatably installed inside the base 5 respectively, the driving gear 15 is meshed with the driven gear 16, the ratchet 12 is rotatably installed on one side of the base 5, the lifting gear 17 is meshed with the lifting rack column 19, and the inside of the base 5 is fixedly connected with a limit plate 21. Through the arrangement of structures such as the turning handle 10 and the display stand 3, the toggle block 13 is pressed and the turning handle 10 is rotated. Through the cooperation of the lifting rack column 19, the driving rotating shaft 11 and the driven rotating shaft 18, the display stand 3 is driven to adjust its height, which is convenient for teachers to adjust the height of the display board according to needs, improve teaching efficiency, and display more teaching content, thereby increasing the flexibility and adjustability of the device.

[0029] like Figure 1 to Figure 5 As shown, a through hole is formed inside the ratchet 12, a round hole is formed inside the turning handle 10, and the active rotating shaft 11 is fixedly nested inside the through hole and the round hole.

[0030] like Figure 1 to Figure 5 As shown, a straight hole is opened on one side of the base 5, and the driven shaft 18 is rotatably installed inside the straight hole.

[0031] like Figure 1 to Figure 5 As shown, two symmetrically arranged sliding holes are provided inside the base 5, and the lifting rack column 19 is slidably assembled inside the sliding holes.

[0032] like Figure 1 to Figure 5 As shown, a through hole is opened inside the lifting gear 17, a middle hole is opened inside the driven gear 16, and the driven rotating shaft 18 is fixedly nested inside the through hole and the middle hole.
