Description

Technical Field

[0001] This invention relates to the field of land and space planning technology, and in particular to a planning publicity and display device. Background Technology

[0002] Territorial spatial planning refers to a systematic, comprehensive, and long-term plan for land use and spatial development in a country or region. It involves the rational use of land, land development and protection, and the organization and adjustment of urban and rural spaces, aiming to achieve balanced development of multiple goals, including economic, social, ecological, and cultural aspects. Territorial spatial planning is mainly promoted through maps or sand tables. However, spatial planning involves a large area, and condensing it onto maps or sand tables limits the detailed presentation of plans for some important areas, affecting the effectiveness of the promotion and resulting in incomplete information delivery. Furthermore, maps or sand tables require support frames or tables for display. Traditional support frames are large, and some large frames have fixed shapes, occupying a significant area. Structural adjustments require manual disassembly and reassembly by staff, which is time-consuming and labor-intensive. Summary of the Invention

[0030] The specific usage and function of this embodiment are as follows: When displaying drawing 503 on display stand 501, the staff can adjust the height of display stand 501 as needed. The staff can start the motor inside motor box 202, which controls the rotation of rotating rod 201. Rotating rod 201 controls the rotation of two sets of lead screws 203 through two sets of bevel gear assemblies on its surface. During the rotation, the threads on the surface of lead screw 203 can push lifting rod 204 to slide up and down, thereby achieving the purpose of controlling the height of display stand 501. After the height of display stand 501 is adjusted, the staff can insert the insertion rod 701 between the two sets of support columns 605. Since the bottom of support column 605 is approximately triangular, during the insertion process, support column 605 is subjected to force and slides outward, and support column 605 slides into the support. Inside the groove 702, the promotional highlight expansion mechanism 7 is installed on the surface of the elastic support mechanism 6. At this time, the support column 605 is inside the support groove 702. The promotional highlight expansion mechanism 7 can slide laterally as needed. When it is necessary to focus on a certain area, the promotional highlight expansion mechanism 7 can be slid to one side of this position, and the magnetic fixing rod 707 can be pulled. The magnetic fixing rod 707 drives the guide rope 706 to extend and insert the magnetic fixing rod 707 into the key promotional area. Since the surface of the display stand 501 is equipped with a magnetic plate 502, the magnetic fixing rod 707 can be fixedly placed in this area. When rotating the display, the elastic automatic winding rod 708 can be pulled to pull out the promotional expansion paper 709 from inside the top box 704. The promotional expansion paper 709 can provide a detailed and comprehensive planning and display of the planning and design of this important area.When displaying drawing 503, vertical display is required, or when the device needs to be stored, the motor inside the motor housing 202 starts, and the lifting rod 204 slides continuously upward. The lifting sliding rod 401 slides upward under force. When the display platform 501 slides upward to a certain height, the driving tooth B404 on the surface of the auxiliary rotating rod 403 at the bottom end of the lifting sliding rod 401 contacts the rack plate A104 in the middle set of fixed rods 102. The lifting sliding rod 401 continues to slide upward, and the driving tooth B404, affected by the rack plate A104, drives the auxiliary rotating rod 403 to rotate. One end of the auxiliary rotating rod 403 controls the rotation of the rotating screw 402 through a bevel gear assembly. The threads on the surface of the rotating screw 402... During rotation, the lifting frame 405 slides upward. The rack plate B406 at the top of the lifting frame 405, while sliding, drives the gear A303 to rotate the driving rod 302. Since two sets of linkage gears 304 are fixedly installed at both ends of the driving rod 302, the rotation of the linkage gears 304 further controls the rotation of the rotation support gear 306 and the bracket 305. The bracket 305 rotates, and the bracket and display component 5 can rotate at the required angle, making it easier to plan and display the drawing 503. The bracket 305 and display component 5 can rotate 90 degrees, and are parallel to the fixed rod 102, allowing for storage and placement of the device.
