Description

Technical Field

[0001] The utility model relates to the technical field of sand painting demonstration devices, and more specifically, to a sand painting demonstration device. Background Art

[0002] Under current technical conditions, sand painting demonstration devices are important tools for artists and performers to create and display sand paintings. However, existing sand painting demonstration devices have some inconveniences during use. First, existing devices are often not convenient to adjust the height. This means that performers cannot adjust the height of the device according to their own height or sitting posture during use to adapt to different performance environments and needs. This not only affects the performer's comfort, but may also affect the coherence and artistic effect of the performance.

[0003] Secondly, the existing sand painting demonstration device cannot easily adjust the clamping force when in use. The clamping force refers to the force with which the device fixes the sand painting board on the demonstration table. If the clamping force is too large, it may damage the sand painting board and affect the quality of the sand painting; if the clamping force is too small, it may cause the sand painting board to shift or shake during the performance, affecting the stability and safety of the performance. Therefore, the existing device may have certain safety risks during use and is not convenient enough. Utility Model Content

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a sand painting demonstration device, which has the following beneficial effects:

[0017] 1. The design of the adjustment mechanism allows the user to adjust the height of the sand painting demonstration device as needed to adapt to the height or sitting posture of different performers. By pressing the handle, the folding plate drives the guide sleeve to move upward, thereby changing the position of the limit frame. Since the sand painting receiving plate is placed in the limit frame, this movement allows the height of the sand painting to be adjusted accordingly, ensuring that the performer can create in a comfortable and appropriate position. This adjustment mechanism not only improves the performer's comfort and convenience, but also enhances the artistic effect and viewing value of the sand painting performance.

[0018] 2. The connection mechanism realizes a firm connection between the fixed sleeve and the guide sleeve through the cooperation of the threaded section and the hexagonal sleeve. This design ensures the stability and safety of the sand painting demonstration device and prevents accidental displacement or shaking during the performance. At the same time, by pressing the pressure rod, the receiving ring is pressed on the elastic sheet, which releases the clamping connection between the elastic sheet and the annular groove, so that the lateral block can be pulled out, thereby conveniently releasing the connection. This design not only improves the convenience of operation, but also reduces the difficulty of maintenance and replacement of parts.

[0019] 3. The pushing mechanism realizes the smooth pushing of the guide sleeve through the cooperation of the side plate, folding rod and handle. By pressing the handle, the folding rod drives the guide sleeve to move upward, thereby changing the position of the limit frame and adjusting the height of the sand painting. This design simplifies the operation process and improves the accuracy and efficiency of the adjustment. At the same time, it also ensures the safety and stability of the performers during the performance, and improves the overall quality and viewing of the performance.
