Problems solved by technology

[0005] The common feature of above two kinds of products is that they all only comprise two blackboards or writing boards, wherein each board can move left and right or left and right up and down, like this, when the area of ​​each board is very big, there will be inconvenience to use. Even if the writing board is pulled to the lowest end, it is not easy to write on the top of the writing board, so that the utilization rate of the writing board is reduced. In addition, if the writing board adopts an up and down movement mechanism with a counterweight, the overall weight will be increased. potential safety hazards, and in large lecture theaters, in order to meet the viewing needs of the audience in the back row, the writing board is often made very large. On the other hand, the writing board in the prior art generally uses sprockets when moving up and down. Synchronization is achieved by cooperating with the sprocket shaft, which increases the complexity of the structure and also increases the cost of the product

Embodiment 1

[0029] like figure 1 , 2 , 3, 4, 5, a combined multimedia writing board, which includes a fixed bracket 13 fixed on the wall, and two movable brackets 1 connected with the fixed bracket 13, and also includes a front movable plate body 2 and a rear movable plate body 4, the upper and lower ends of the fixed bracket 13 each have a transverse guide groove 3, and each of the four corners of the back of each movable bracket 1 has a transverse guide wheel 11, wherein the upper two transverse guide wheels 11 are located at In the lateral guide groove 3 at the upper end of the fixed bracket 13, the two lower lateral guide wheels 11 are located in the lateral guide groove 3 at the lower end of the fixed bracket 13, and the lateral guide wheels 11 can roll left and right in the lateral guide groove 3. The cross section is C-shaped, so that the lateral guide wheel 11 can be wrapped to prevent the lateral guide wheel 11 from being separated from the lateral guide groove 3. The top of eac...

Embodiment 2

[0032] like figure 1 , 2 , 3, 4, 6, a combined multimedia writing board, its structure is the same as that of Embodiment 1, except that the upper and lower ends of the back of each movable bracket 1 each have a horizontal guide groove 3, and the fixed bracket 13 has a horizontal Eight lateral guide wheels 11 adapted to the guide grooves 3, each lateral guide groove 3 is matched with two lateral guide wheels 11, the lateral guide wheels 11 can roll left and right in the lateral guide grooves 3, and each lateral guide groove 3 is provided with There are two transverse convex rails 5 with opposite protruding directions, the ring surface of the transverse guide wheel 11 is provided with a second groove for matching with the transverse convex rail 5, and the transverse convex rail 5 extends into the second groove, Therefore, the lateral guide wheel 11 is prevented from being separated from the lateral guide groove 3. In addition, the plate lifter 6 is a sprocket, and the flexible ...

Embodiment 3

[0034] like figure 2 , 3 , 4, 7, 8, a combined multimedia writing board, its structure is the same as that of Embodiment 1, except that the chalk groove 17 and the chalk ash box are located on the fixed bracket 13, and the upper end of the fixed bracket 13 is provided with a cross-section: The C-shaped transverse guide groove 3 is provided with a transverse convex rail 5 at the lower end, and the top of each movable bracket 1 is provided with two transverse guide wheels 11 adapted to the transverse guide groove 3. The transverse guide wheels 11 are located in the transverse guide groove. 3, the bottom end of each movable bracket 1 is further provided with two lateral guide wheels 11, and the ring surface of the lateral guide wheels 11 is provided with a second groove for matching with the lateral convex rail 5. The lateral convex rail 5 Protruding into the second groove, the lateral guide wheel 11 can move laterally on the lateral convex rail 5 .
