Embodiment 1

[0026] A teaching aid device, comprising a carrier board 1, a base 8 and a moving wheel 9, a magnetic writing board 3, a telescopic rod 6 and a height adjustment mechanism 7, the front surface of the carrier board 1 is slidably connected with a The magnetic writing board 3 whose surface moves laterally, the front surface of the magnetic writing board 3 is provided with a magnetic block 31, the bottom of the carrier board 1 is fixedly provided with a mounting mechanism 4, and the mounting mechanism 4 is detachably connected with the mounting block 5, and the mounting block 5 is located in the The top of the telescopic rod 6 and the height adjustment mechanism 7 are fixed on the base 8 at the bottom.

[0027] The working principle of the present invention is as follows: when in use, firstly, the height adjustment mechanism 7 is used to adjust the height of the carrier board 1 to adjust to the required position, and the magnetic writing board 3 is pulled to make the magnetic writi...

Embodiment 2

[0029] On the basis of Embodiment 1, the upper and lower end surfaces of the magnetic writing board 3 are provided with connecting rods 32, and the upper and lower edges of the front surface of the carrier board 1 are provided with protruding mounting portions 11. The opposite surface of the part 11 is provided with a chute 12 , and the chute 12 is slidably connected to a roller 33 , and the roller 33 is connected to the magnetic writing board 3 through a connecting rod 32 . The magnetic writing board 3 is slidably connected with the chute 12 through the roller 33, so that it can move and unfold along the front surface of the carrier board 1 to expose the display screen 2. At the same time, the magnetic writing board 3 is used for displaying paper materials or directly on the magnetic writing board 3. Writing, while achieving multiple functions, takes up relatively little space.

Embodiment 3

[0031] On the basis of Embodiment 1, the mounting mechanism 4 includes a housing 41 for fixing the bottom surface of the carrier plate 1, a concave cavity 42 provided on the bottom surface of the housing 41 and matched with the mounting block 5, a compression spring 43, a moving plate 44, a pressing The rod 45 and the clamping block 46, one end of the compression spring 43 is fixedly connected with the inner wall of the casing 41, and the other end is fixed with a moving plate 44, the moving plate 44 is fixedly connected with one end of the pressing rod 45, and the other end of the pressing rod 45 penetrates out of the casing 41 Externally, the upper and lower ends of the moving plate 44 are slidably connected to the inner wall of the housing 41. The specific structure of the sliding connection may be the slider chute 12 or any other structure capable of realizing the sliding function, which is not limited here. During installation, press the pressing rod 45 inward to compress ...

Abstract

The invention discloses a teaching auxiliary device. The teaching auxiliary device comprises a carrier plate, a base and a moving wheel; the teaching auxiliary device further comprises a magnetic writing pad, a telescopic rod and a height adjusting mechanism; the front surface of the carrier board is slidably connected with the magnetic writing board that can move laterally along the front surfaceof the carrier plate; a magnet is arranged on the front surface of the magnetic writing board; a mounting mechanism is fixedly arranged at the bottom of the carrier plate; the mounting mechanism is detachably connected with a mounting block; the mounting block is arranged at the top of the telescopic rod and the height adjusting mechanism; and the bottoms of the telescopic rod and the height adjusting mechanism are fixed on the base. According to the teaching auxiliary device provided by the invention, video play and material display can be carried out synchronously, the practicability is strong, the installation and disassembly are convenient, carrying is facilitated, the height adjustment is convenient and the operation is simple.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a teaching auxiliary device. Background technique [0002] As an important subject, in the process of teaching, ideology and politics usually use auxiliary devices such as writing boards to better teach and enable students to understand knowledge more clearly and comprehensively. Therefore, auxiliary devices have an important role in teaching. effect. [0003] However, the existing auxiliary device usually fixes the display board or writing board directly on the bracket, which is inconvenient to adjust the height. Due to the large size, it cannot be disassembled, which makes it inconvenient to carry. In addition, the function of the existing auxiliary device is relatively simple. , it is inconvenient to perform video playback and material display at the same time as lecturing and writing, and its practicability needs to be improved. SUMMARY OF THE INVENTION [0004...
