Description

Technical Field

[0001] The utility model relates to the technical field of urban and rural planning, in particular to an urban and rural planning design blueprint publicity device. Background Art

[0002] Urban and rural planning is a general term for urban system planning, city planning, town planning, township planning and village planning. Urban and rural planning design blueprint display devices are needed to display the design blueprints of urban and rural planning to ensure openness, fairness and transparency.

[0003] A design blueprint display device for urban and rural planning with publication number CN215417457U comprises: a column, a telescopic rod is arranged above the column, the telescopic rod is fixed to a display board, and the display board is used to post the design blueprint, a transparent window is installed on one side of the display board, and the design blueprint can be viewed through the transparent window, and the transparent window can provide certain protection for the internal design blueprint; a telescopic slot is provided inside the telescopic rod, and the telescopic rod is connected to the column through the telescopic slot. After the urban and rural planning blueprint is posted on the display board, the transparent window is closed, and then the rotating rod is rotated so that the rotating rod is connected to the limit seat, and the transparent window can be fixed. The bottom plate fixed at the bottom of the base has a large area, and the buffer groove can enhance the friction between the bottom plate and the ground. At the same time, stones or counterweights can be placed inside the base to press the bottom plate, thereby achieving the effect of stabilizing the device. In addition, the existing display device also has the following disadvantages during use:

[0004] (1) In the existing public display device, if the display window height is to be adjusted, multiple people need to work together to lift the display window to a predetermined height and then have others operate the structure to clamp the display window, which wastes labor and is inconvenient to use. Moreover, if the display window deviates during the process of lifting, it will cause certain damage to the device body, thereby affecting the service life and reliability.

[0005] (2) Existing public notice devices lack a supporting structure. With only a base support, it is difficult for them to maintain stability on uneven terrain. This not only limits their scope of application, but may also affect the display effect of the notice content and the public’s reading experience. Utility Model Content
