Description

Technical Field

[0001] The utility model belongs to the technical field of performance display, and particularly relates to a performance display stand. Background Art

[0002] The display stand used to display performance information is usually made of solid materials, and its main structure is stable. It has a flat and wide display blackboard, which can display various performance data, charts and other information. The surface is specially treated to ensure smooth writing and wiping. However, the current display stand used for displaying performance information has many obvious disadvantages in that it is inconvenient to adjust the viewing angle and viewing direction during use, which greatly limits the effect of information communication. The fixed display stand is inconvenient to adjust and cannot obtain the best viewing experience during use, which makes it difficult for people to obtain performance information clearly and accurately, thereby affecting the understanding and grasp of the overall situation. For some places with special spatial layouts, such as corners or places with obstacles, the fixed-angle display stand may not be able to fully display the information to all relevant personnel, resulting in missing and incomplete information transmission. In short, the current display stand used for displaying performance information is not adjustable in viewing angle and viewing direction, which seriously affects its use effect and brings many inconveniences and problems to actual work and information exchange. It is urgently needed to be improved and optimized, so it is necessary to develop a performance display stand to solve these problems. Utility Model Content
