For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0043] Urban and rural planning display boards are generally posted by the government with the results of urban and rural planning, and then placed on display racks for public display. Depending on the planning stage, the display content on the display board needs to be changed, and users often need to remove the display board and update the display content.

[0044] However, during the installation process, one person needs to hold the display board to prevent it from shifting, and another person needs to adjust the clamping device to position the two ends of the display board to complete the positioning and installation of the display board. This method requires the collaboration of multiple people, which is time-consuming and labor-intensive.

[0045] In order to solve the problems in the related technology to a certain extent, the embodiment of the present application provides an urban and rural planning exhibition board. When it is needed, the exhibition board 15 only needs to be placed on the box body 21, and then the positioning column 22 is inserted into the exhibition board 15. After the exhibition board is positioned, the knob 254 is turned to make the clamping plate 1 253 slide, and the clamping plate 255 is used to clamp and fix the exhibition board 15 to complete the installation of the exhibition board 15.

[0046] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0047] Combination Figure 1-Figure 7The embodiment of the present application provides an urban and rural planning exhibition board, including a display device 1; the display device 1 includes: an electric telescopic rod 12 is arranged on the top of a bottom plate 11, and a universal wheel 13 is arranged at the bottom of the bottom plate 11; a support plate 14 is arranged on the top of the electric telescopic rod 12; a disassembly and assembly device 2 is arranged on the display device 1, and the disassembly and assembly device 2 includes: a box body 21 is arranged on the top of the support plate 14, and an exhibition board 15 is arranged on the top of the box body 21; a positioning column is arranged through the exhibition board, and the positioning column and the box body are plugged together, a positioning column 22 is arranged through the exhibition board 15, and the positioning column 22 and the box body 21 are plugged together, a groove is opened on the positioning column 22, a spring 23 is arranged in the groove, a rod body 231 is arranged on the spring 23, and a hole matching the rod body 231 is opened on the box body 21; a clamping component 25 is arranged on the support plate 14.

[0048] Urban and rural planning display boards are generally posted by the government on the results of urban and rural planning, and then the display boards are placed on display racks for public display. According to different planning stages, the display content on the display boards needs to be changed, and the display content sometimes includes some physical objects. Because this type of display content is heavy, directly gluing it on the vertical display board 15 will result in loose bonding and easy to fall off. It is necessary to place the display board 15 horizontally, glue the display content on the display board 15, and then stand the display board 15 upright after the glue is dried to ensure that the display content will not fall off the display board 15. Therefore, users often need to remove the display board 15 and then update the display content. The user first places the display board 15 on the box body 21, and then inserts the positioning column 22 into the display board 15. After the positioning column 22 is inserted to the bottom, it is plugged into the support plate 14. At the same time, the iron sheet at the bottom of the fixing frame 225 and the support plate 14 are fixed. The bolts can be used to fix the connection, and the positioning column 22 can ensure that the display board 15 does not fall on the top of the box body 21 to prevent the display board 15 from being damaged. The box body 21 is provided with a hole that matches the rod body 231 for insertion. Therefore, during the downward movement of the positioning column 22, the rod body 231 is supported by the wall of the positioning column 22 and moves downward. After the positioning column 22 is inserted to the bottom of the box body 21, the rod body 231 is aligned with the preset hole on the box body 21. Under the elastic force of the spring 23, the spring 23 drives the rod body 231 to extend out of the hole on the box body 21, thereby limiting the up and down movement of the positioning column 22, improving the stability of the positioning column 22, and preventing the positioning column 22 from being pulled out due to accidental contact with external force. After positioning is completed, the display height of the display board 15 can be adjusted using the electric telescopic rod 12, and the cooperation of each component improves the installation and removal efficiency of the display board 15.

[0049] In some embodiments, a positioning block 211 is provided on the box body 21, and a positioning groove 212 is provided on the display board 15, and the positioning block 211 and the positioning groove 212 are plugged in. The positioning block 211 and the positioning groove 212 are consistent in shape and size and are distributed on both sides of the center of the display board 15. Therefore, the positioning block 211 and the positioning groove 212 can position the display board 15 while ensuring the stability of the display board 15, which is convenient for the subsequent positioning of the positioning column 22.

[0050] In some embodiments, the top of the positioning column 22 is threadedly connected with a threaded member 221, the bottom of the threaded member 221 is provided with a bearing 222, a limiting block 223 is provided on the bearing 222, and a limiting groove 224 is provided on the display board 15. After the user inserts the positioning column 22, the threaded member 221 is turned, and the threaded member 221 drives the inner ring of the bearing 222 to rotate. The limiting block 223 fixedly connected to the outer ring of the bearing 222 can be manually adjusted to enter the limiting groove 224, and then the threaded member 221 is turned to press the limiting block 223 to fix the top of the positioning column 22. The top and bottom of the positioning column 22 are fixed, and it is more stable when inserted into the display board 15.

[0051] In some embodiments, the diameter of the empty slot inside the display board 15 for the positioning column 22 to be inserted is larger than the diameter of the positioning column 22, and the head of the rod body 231 is arc-shaped. A little space is left inside the display board 15, and when the user needs to remove the positioning column 22, he presses the rod body 231 and pulls the positioning column 22 upward, driving the rod body 231 to slide inside the display board 15. Because the head of the rod body 231 is arc-shaped, the friction is small and the sliding is smoother.

[0052] In some embodiments, the clamping assembly 25 includes: a screw 251 penetratingly disposed on the support plate 14; a slider 252 disposed on the screw 251; a clamping plate 1 253 disposed on the slider 252; and a clamping plate 255 fixedly connected to the support plate 14. The display board 15 is relatively large in size and is prone to tilting forward on the box body 21, so the display board 15 needs to be protected. The user controls the slider 252 to move horizontally by rotating the screw 251, driving the clamping plate 1 253 to move horizontally to clamp the display board 15. At the same time, the clamping plate 255 is fixed, so as the clamping plate 1 253 moves, the distance between the two clamping plates becomes smaller and smaller, so that the display board 15 can be clamped. The display area on the display board 15 is set in the middle of the display board 15, and the fixed blank area is next to it. The clamping plate 1 253 contacts this area, so the clamping plate 1 253 will not block the content of the display board 15.

[0053] In some embodiments, a serrated knob 254 is provided on the screw rod 251. The serrated knob 254 has a better friction coefficient, and the user can rotate the screw rod 251 more conveniently.

[0054] In some embodiments, sponge gaskets are provided on the clamping plate 1 253 and the clamping plate 2 255. The sponge gaskets are made of soft materials and can protect the display board 15 to prevent damage to the display board 15 during the clamping process.

[0055] In some embodiments, a telescopic rod 24 is fixedly connected to the bottom of the support plate 14, and fixing holes are provided on the telescopic end and the retracted end of the telescopic rod 24, and a latch 241 is provided at the connection of the fixing holes. The telescopic rod 24 follows the electric telescopic rod 12 to rise and fall, and after the height adjustment is completed, the latch 241 can be inserted to stop the movement of the telescopic rod 24 so that the support plate 14 is supported and fixed, thereby strengthening the supporting effect on the support plate 14.

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.

[0057] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
