Description

Technical Field

[0001] This utility model relates to the field of model installation, specifically to a device for demonstrating and assembling urban planning road networks. Technical Background

[0002] Against the backdrop of the accelerated development of smart cities, 3D city modeling technology has become a core supporting tool in fields such as urban planning and traffic management. As the core framework of urban spatial structure, the road network has an increasingly prominent need for visualization demonstration and dynamic adjustment of its planning scheme. As a result, urban planning road network demonstration splicing devices have become a key carrier connecting virtual data and physical display, and are widely used in diverse scenarios such as project discussions, public communication, and teaching and training.

[0003] Existing road network demonstration splicing devices mostly involve directly splicing demonstration boards on a tabletop. These devices lack a good limiting and fixing structure, and the demonstration boards are in direct face-to-face contact during splicing. When installing demonstration road models, the demonstration boards are easily broken apart by external forces. A few splicing devices with limiting structures have gaps between the demonstration boards due to the limiting effect, which prevents them from completely fitting together to form a perfect demonstration plane, thus affecting the demonstration effect. Utility Model Content

[0004] (I) Technical Issues

[0005] The technical problem to be solved by this utility model is that the splicing device in the prior art lacks a good limiting and fixing structure, and the demonstration board is easily broken apart by external force.

[0006] (II) Technical Solution

[0007] To address the above technical challenges, this solution provides an urban planning road network demonstration splicing device, achieved through the following technical means:

[0008] A city planning road network demonstration splicing device includes a base, a plurality of demonstration boards are slidably connected to the upper end of the base, a fixing plate is fixedly provided on the upper surface of the base, and a pair of end plates are symmetrically provided on the left and right ends of the upper surface. A pair of U-shaped through slots are symmetrically opened on both sides of the fixing plate. One end of the demonstration board is inserted into the U-shaped through slot and the other end is inserted into the end plate. The device also includes a clamping structure set in the U-shaped through slot.

[0009] As an improvement, the demonstration board has an extension plate integrally formed on one side and a through groove on the other side.

[0010] As an improvement, the clamping structure includes several sliding cylinders that are fixedly arranged at equal intervals on the upper end of the inner wall of the U-shaped through groove. Each sliding cylinder has a sliding rod slidably connected to its inner wall. The sliding rods are divided into two groups, and a pressure plate is integrally fixedly connected to the bottom surface of each group of sliding rods. The bottom surface of the pressure plate is in contact with the upper surface of the extension plate.

[0011] As an improvement, a spring is fitted onto the surface of the slide rod, with one end of the spring fixedly connected to the bottom surface of the slide cylinder and the other end fixedly connected to the upper surface of the pressure plate.

[0012] As an improvement, a pair of side plates are integrally formed on the side of the end plate near the fixed plate, and a number of equally spaced rollers are rotatably connected on the two sides of the pair of side plates that are close to each other, and the surface of the rollers contacts one side of the inner wall of the through groove.

[0013] As an improvement, a pair of magnetic blocks are fixedly installed on both sides of the fixed plate on the upper surface of the base. A slot is opened on the bottom surface of one end of the demonstration board to engage with one side of the magnetic block. A magnetic strip is fixedly pasted on one side of the slot.

[0014] (III) Technical Effects

[0015] The advantages of this utility model compared with the prior art are:

[0016] 1. A good clamping and fixing structure is set up. The slide bar surface is sleeved with a spring, and the bottom surface of each slide bar is integrally fixed with a pressure plate. When the extension plate on the demonstration board is inserted into the U-shaped through groove, the upper surface of the extension plate contacts the bottom surface of the pressure plate, the spring is compressed under force, and there is always a downward force on the pressure plate. The extension plate can be clamped and fixed by the pressure plate, thereby fixing the entire demonstration board.

[0017] 2. A positioning structure is set up. A pair of magnetic blocks are fixed on both sides of the fixed plate on the upper surface of the base. The bottom surface of the demonstration board has a slot that engages with the magnetic blocks. A magnetic strip is fixedly pasted on one side of the slot. The magnetic attraction between the magnetic blocks and the magnetic strip can quickly position the demonstration board in the correct position. And because the engagement between the magnetic blocks and the slot has a certain limiting effect on the demonstration board, the demonstration board will not shift.

[0018] 3. A pair of end plates are symmetrically arranged on the left and right ends of the upper surface of the base. A pair of side plates are integrally formed on one side of the end plates. Several rollers with equal spacing are rotatably connected to the two sides of the side plates that are close to each other. The surface of the rollers contacts the through groove on one side of the demonstration board to reduce the friction force on the demonstration board during installation and make the installation smoother.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Additionally, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] A city planning road network demonstration splicing device, such as Figure 1 , Figure 2 As shown, it includes:

[0028] The system includes a base 1, with several demonstration boards 2 slidably connected to its upper end. Each demonstration board 2 has an extension plate 13 integrally formed on one side and a through groove 14 on the other side. A fixing plate 3 is fixedly mounted on the upper surface of the base 1, and a pair of end plates 4 are symmetrically arranged on the left and right ends of the upper surface. A pair of U-shaped through grooves 10 are symmetrically arranged on both sides of the fixing plate 3. Four demonstration boards 2 are evenly distributed on both sides of the fixing plate 3. One end of each demonstration board 2 is inserted into the U-shaped through groove 10, and the other end is inserted into the end plate 4. The system also includes a clamping structure disposed within the U-shaped through groove 10.

[0029] like Figure 3As shown, the clamping structure includes several sliding cylinders 7 arranged at equal intervals on the upper end of the inner wall of the U-shaped through groove 10. Each sliding cylinder 7 has a sliding rod 8 slidably connected to its inner wall. The sliding rods 8 are divided into two groups. Each group of sliding rods 8 has a pressure plate 6 integrally fixedly connected to its bottom surface. The bottom surface of the pressure plate 6 is in contact with the upper surface of the extension plate 13. A spring 9 is sleeved on the surface of the sliding rod 8. One end of the spring 9 is fixedly connected to the bottom surface of the sliding cylinder 7, and the other end is fixedly connected to the upper surface of the pressure plate 6. When the upper surface of the extension plate 13 contacts the bottom surface of the pressure plate 6, the spring 9 is compressed and always exerts a downward force on the pressure plate 6. The extension plate 13 can be clamped and fixed by the pressure plate 6, thereby fixing the demonstration plate 2 as a whole.

[0030] A pair of side plates 12 are integrally formed on the side of the end plate 4 near the fixed plate 3. Several equally spaced rollers 5 are rotatably connected to the two sides of the pair of side plates 12 that are close to each other. The surface of the rollers 5 contacts one side of the inner wall of the through groove 14, which can reduce the friction force on the demonstration plate 2 during installation and make the installation smoother. The upper side plate 12 of the pair of side plates 12 is on the same horizontal plane as the end plate 4. The through groove 14 has a U-shaped structure and the lower end face is narrower than the upper end face. The lower end face of the through groove 14 is in contact with the bottom surface of the side plate 12 near the base 1, and the upper end face is in contact with the upper side plate 12 and the upper surface of the end plate 4. This structural design allows the demonstration plate 2 to be spliced ​​with the other demonstration plate 2 and the fixed plate 3 to form a complete plane without any extra gaps. The overall appearance after splicing is more beautiful and convenient for demonstration.

[0031] like Figure 4 As shown, a pair of magnetic blocks 11 are fixedly mounted on both sides of the fixing plate 3 on the upper surface of the base 1. A slot 15 is opened on the bottom surface of one end of the demonstration board 2 to engage with one side of the magnetic block 11. A magnetic strip 16 is fixedly attached to one side of the slot 15. The magnetic attraction between the magnetic block 11 and the magnetic strip 16 can quickly position the demonstration board 2 in the correct position. Furthermore, due to the engaging action between the magnetic block 11 and the slot 15, the demonstration board 2 will not shift.

[0032] In the specific implementation of this embodiment:

[0033] In use, select an appropriate number of demonstration boards 2 according to the area required for the road network demonstration and splice them together. Align the extension plate 13 on the demonstration board 2 with the groove formed by the pressure plate 6 and the lower surface of the U-shaped groove 10, so that the extension plate 13 is inserted into it. During the insertion process, due to the compression of the spring 9, there is always a downward force on the pressure plate 6. The extension plate 13 can be clamped and fixed by the pressure plate 6, so that the demonstration board 2 is fixed as a whole. At the same time, the groove 14 on the other side of the demonstration board 2 is inserted and fixed with the surface of the fixing plate 3 and the side plate 12. During the insertion process, the surface of the rollers 5 on the two side plates 12 contacts the inner side of the groove 14, reducing friction and making the movement of the demonstration board 2 smoother during insertion. The magnetic block 11 set on the base 1 magnetically engages with the slot 15 opened on the bottom surface of one end of the demonstration board 2 for quick positioning. After splicing, the road network model can be laid out on the demonstration board 2.
