[0021] Example 1

[0022] In the prior art, since the height of the display board is difficult to adjust, it is difficult for the user to adjust the height of the display board body 3 according to his or her own height during use, which has certain limitations.

[0023] Based on this, the utility model provides a writing display board, comprising a support column 1, a U-shaped frame 2 arranged at the top of the support column 1, a display board body 3 slidably arranged in the U-shaped frame 2, a collection trough 6 arranged at the bottom end of the display board body 3, and a telescopic component 4 arranged between the bottom end of the display board body 3 and the bottom wall of the U-shaped frame 2. Figure 1 and Figure 2 As shown, the telescopic component 4 is a hydraulic rod, which is fixed to the inner bottom wall of the U-shaped frame 2, and the bottom wall of the display board body 3 is connected to the telescopic end of the hydraulic rod. Figure 1-3 As shown, sliders 12 are provided on both sides of the display board body 3 , and vertical sliding grooves that slide with the sliders 12 are provided on the inner walls of both sides of the U-shaped frame 2 .

[0024] Working Principle: The user stands in front of the display board 3 and writes on it using chalk (in this case, the front of the display board 3 is set as a blackboard) or a whiteboard marker (in this case, the front of the display board 3 is set as a whiteboard). If the display board 3 is not suitable for the user's height, the telescopic assembly 4 is activated, causing the display board 3 to move up and down within the U-shaped frame 2. During this movement, the slider 12 slides up and down within the vertical slot to limit the display board 3 and improve the smoothness of the vertical movement of the display board 3. The hydraulic rod can be opened and stopped at will, allowing the display board 3 to stop at any height that suits the user.

[0025] When the display board body 3 is wiped during or after writing, some pencil shavings will be generated. The pencil shavings will be collected by the collecting trough 6 to minimize the extent to which they fall directly onto the ground.

[0026] Further, such as Figure 1-2 As shown, a sponge 5 is provided in the collecting trough 6, and the sponge 5 abuts against the inner wall of the collecting trough 6. A discharge port is provided on one side of the collecting trough 6, and a collecting box 7 with an open top is provided outside the discharge port. In this solution, when a large amount of pencil shavings are collected in the collecting trough 6, the sponge 5 is pressed by hand and moved toward the discharge port to push the pencil shavings in the collecting trough 6 to the discharge port and collect them in the collecting box 7. The material of the collecting box 7 can be selected to be relatively light, and in order to observe the amount of pencil shavings collected in the collecting box 7 at any time, the collecting box 7 can also be set to a transparent material.

[0027] Further, such as Figure 1-2 As shown, a U-shaped block 8 is provided at the bottom end of the aggregate trough 6, and a limiting block 9 is provided on the side wall of the aggregate box 7. The limiting block 9 is horizontally inserted into the gap formed by the U-shaped block 8 and the bottom wall of the aggregate trough 6. In specific implementation, the limiting plate provided on the front side of the aggregate trough 6 is horizontally inserted into the gap formed by the U-shaped block 8 and the bottom wall of the aggregate trough 6 to limit the aggregate box 7 to the bottom wall of the aggregate trough 6. At the same time, because the limiting block 9 is detachably provided in the gap formed by the U-shaped block 8 and the bottom wall of the aggregate trough 6, when there is a lot of material in the aggregate box 7 that needs to be poured out, the limiting block 9 can be taken out from the gap at any time to improve the convenience of disassembling the aggregate box 7.

[0028] Further, such as Figure 1-3 As shown, the top of the sponge 5 is provided with a top base 10, and the top base 10 is provided with a handle 11. In this solution, by providing the handle 11, the user can directly hold the handle 11 to push the sponge 5, which effectively improves the convenience of pushing.

[0029] Furthermore, in addition to being able to write, the writing display board can also be used to exhibit or demonstrate pictures. In order to limit the position of pictures during the picture demonstration, such as Figure 1 and Figure 3 As shown, a slide rod 16 is provided on the front side of the display board body 3, and a plurality of dovetail clips 13 (existing technology) are movably provided on the slide rod 16. The dovetail clips 13 can slide left and right on the slide rod 16. In specific implementation, the top of the picture is clamped by the dovetail clips 13 to achieve the purpose of limiting the picture to the front side of the display board body 3.

[0030] Furthermore, because some images are inherently curled, if only the top is clamped, the lower portion will still curl. To address this, the writing side of the display board body 3 is made of a magnetic material, and multiple detachable pressing plates (not shown in the figure, according to prior art) are installed on the display board body 3. Each pressing plate is magnetically connected to the display board body 3. In practice, the image is first flattened from top to bottom, and then the pressing plate is placed under the image. Because the pressing plate and the display board body 3 are magnetically connected, when the pressing plate is placed directly under the image, it directly connects to the front side of the display board body 3, thereby securing the lower portion of the image and preventing it from curling.

[0031] Furthermore, in order to improve the stability of the display board, Figure 1 As shown, a support base 15 is provided at the bottom end of the support column 1, and a lockable universal wheel (existing technology, not shown in the figure) is provided at the bottom end of the support base 15.

[0032] It is worth noting that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "longitudinal", "horizontal" and so on, which refer to the orientation or position relationship in this patent, are based on the attached Figure 1 The orientation or position relationship shown.
