Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of splicing sand table structure design, and particularly relates to a splicing sand table for urban layout planning. Background Technique
[0002] In the process of urban layout planning, planners often use a practical tool to help them better understand and display the blueprint of urban planning, which is the splicing sand table. The splicing sand table is an indispensable tool in urban layout planning, which helps planners understand and display the development of the city in an intuitive way. This model usually consists of multiple parts, which are finally assembled together to form a large-scale urban model, enabling planners to visually see the structure and development of the city in three-dimensional space. Although splicing sand tables are widely used in urban planning, they are not without disadvantages. One significant problem is the lack of stability. Since the splicing sand table is composed of multiple independent parts, the connection between these parts may not be firm enough, and it is easy to shift or fall off during use, especially when the model needs to be frequently moved or adjusted. This instability not only affects the service life of the model but may also have a negative impact on the accuracy and efficiency of planning.
[0003] The patent with the publication number CN214587635U discloses a splicing sand table for urban layout planning in regional planning, which is provided with multiple groups of display structures that are spliced with each other and can be conveniently disassembled and assembled; a separately arranged module structure is installed through the suction cups at its bottom. However, for the above-mentioned splicing sand table, the cross-shaped spacer frame composed of spacer plates, and each display structure is placed in the spacer frame. Obviously, the combined assembly structure of each display structure is easy to loosen and displace, making the combination of each display structure not firm; moreover, for the display structure where a model needs to be added or placed above, it is installed on the display structure by means of suction cups. Although the suction cup method is easy to install, since a light strip is also set for illumination during the display process of the splicing sand table, the heat emitted by the illumination may cause the connection of the suction cup to loosen or even break away from the adsorption surface, resulting in the instability of the overall sand table. Utility Model Content
[0004] Based on the above description, the utility model aims to provide a splicing sand table for urban layout planning to overcome the deficiencies of the loose connection of the combined components of the splicing sand table and the instability of model installation existing in the above situation.

[0042] Example 1
[0043] like Figure 1-6 As shown, an embodiment of the present application provides a splicing sand table for urban layout planning, which includes a base 3, a support plate and several clips 2.
[0044] The base 3 serves as the foundation of the entire sandbox and provides a solid platform for the support plates in the sandbox, which is used to support the plates and sandbox units above the base 3.
[0045] In this embodiment, the bottom bracket 3 can be a plate-shaped structure or a trough with the mouth facing upward. The lower end surface of the bottom bracket 3 is provided with columns 31, preferably four columns, which provide additional support to ensure the stability and practicality of the entire sandbox structure during use.
[0046] The support plate is formed by splicing a plurality of support units 1 arranged on the base 3, and a connection portion for connecting to the sandbox is formed on the support unit 1.
[0047] Preferably, the outer contour of the support unit 1 is a square, and the sides of two adjacent support units 1 close to each other are butted together. This design simplifies the splicing process, so that each support unit 1 can be connected in a unified manner in both the horizontal and vertical directions.
[0048] In an embodiment of the present application, the connecting portion includes a connecting hole 11 formed in the middle of the supporting unit 1. In other embodiments, the connecting portion may be an outwardly convex rod or a concave groove.
[0049] Each of the clamping members 2 fixes two adjacent support units 1 ; specifically, the support unit 1 is provided with four clamping holes 12 evenly distributed circumferentially around the connection hole 11 , and the clamping holes 12 are specifically used for clamping the clamping members 2 , thereby realizing the connection between the support units 1 .
[0050] The connecting portion comprises a connecting hole (11) formed in the middle of the supporting unit, and four clamping holes (12) are respectively formed on four circumferential sides of the connecting hole (11) corresponding to each other, for connecting with the clamping member (2); adjacent supporting units 1 are connected by the clamping member 2 to form an integral network structure, thereby ensuring their accuracy and stability during the splicing process.
[0051] Among them, the cross-section of the snap-fit hole 12 is circular, rectangular or square, and the cross-section of the connecting hole 11 is circular, rectangular or square. In the first preferred embodiment of the present application, the cross-section of the snap-fit hole 12 is circular, and the cross-section of the connecting hole 11 is square.
[0052] Among them, four grooves 13 with openings facing upward are arranged on the upper end surface of the support unit 1, corresponding to each clamping hole 12 respectively, and one end of each groove 13 is connected to the corresponding clamping hole 12 respectively. This design allows the clamp 2 to be smoothly inserted and fixed.
[0053] The card 2 adopts a door-shaped design, such as Figure 4 and Figure 6As shown, it includes a card plate 21 and card columns 22 located at both ends of the card plate 21. The shape of the card columns 22 is adapted to the card holes 12, and the distance between the two card columns 22 matches the distance between the two adjacent card holes 12 in the adjacent support units 1. This design ensures that the card 2 can connect and fix the two adjacent support units.
[0054] For ease of operation, a lifting ring 23 is provided on the upper end surface of the clamping plate 21 of the clamping member 2, so that the clamping member 2 can be easily pulled out. Preferably, a groove 24 is provided on the clamping plate 21, and the lifting ring 23 is located in the groove 24. This design ensures that the lifting ring 23 does not affect the layout of the sand table unit, so that the sand table unit can be laid out smoothly on the upper surface of the assembled support unit.
[0055] In this embodiment of the urban layout planning mosaic sand table, each support unit 1 is connected by a clamp 2 and then arranged on a base 3. The length and width of the overall structure formed by the spliced support units 1 are adapted to the accommodation space on the upper surface of the base. In actual operation, the size of the base 3 and the number of support units 1 can be customized according to actual needs.
[0056] During assembly, first insert the clip 2 into the two adjacent clip holes 12 of two adjacent support units 1. Through horizontal and vertical assembly, a rectangular stable structure is formed. A connection portion that matches the connection hole 11 of the support unit 1 is also fixed to the lower end surface of the sandbox unit. Inserting the sandbox unit into the corresponding support unit connection hole 11 can firmly fix the sandbox unit, effectively preventing the sandbox unit from moving and improving the overall stability of the sandbox. Each sandbox unit is designed to be square, and after assembly, it can adapt to the outer contour of the support unit; alternatively, it can be designed to be rectangular or other shapes, so that the outer contour after assembly is compatible with the outer contour of the support unit after assembly.
[0057] The splicing sand table in this embodiment is used in urban layout planning to provide a very easy-to-operate structure for adjusting or maintaining the contents displayed on the sand table. The displayed sand table units are arranged in the connecting blocks 11 of the corresponding support units according to their sizes, which not only ensures a stable connection but also facilitates removal and replacement. The support units 1 are connected via the clips 2 to form a stable support system. The design of the connecting holes 11 and the clip holes 12 in the middle of the support units can simultaneously meet the requirements of easy installation and removal of the sand table units and the requirements of stable support for the sand table. In summary, the design of the splicing sand table for urban layout planning fully considers the convenience, stability and scalability of use. The support units connected by clips and the sand table units that are easy to install and remove enable planners to efficiently carry out urban planning, demonstration and maintenance operations.
[0058] Example 2
[0059] The clamping hole 12 of the support unit 1 in this embodiment is different from that in the first embodiment. Figure 7-11 As shown, the engaging holes 12 in this embodiment are in the shape of a regular quadrangular prism, and the connecting holes 11 are also designed in the shape of a regular quadrangular prism. When the engaging holes 12 are in the shape of a regular quadrangular prism, the connecting holes 11 are connected to the four engaging holes 12. In order to enhance the stability of the edge support unit 1, auxiliary limiting columns 4 adapted to the engaging holes 12 are also provided. These auxiliary limiting columns 4 are installed in the connecting holes 12 of the support unit 1 located at the edge that are not engaged with the clamping member 2. They can prevent the connection portion of the sandbox unit and the clamping column of the clamping member 2 from moving, thereby ensuring the connection stability between the support unit and the adjacent support unit and the stability of the sandbox unit installed on the support unit.
[0060] Specifically, a groove is also formed on the upper end surface of the auxiliary limiting column 4 , and a ring body 41 is rotatably arranged in the groove so that the auxiliary limiting column 4 can be easily moved out when needed.
[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
