This may prevent users from accurately judging the rationality of local planning. Utility Model Content

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figures 2-4This utility model provides an embodiment of a simulation sand table for integrated urban-industrial planning, comprising a sand table 1, a connecting frame 2 rotatably connected to the bottom of the sand table 1, two rotating rods 3 rotatably connected to the connecting frame 2, a rotating frame 4 rotatably connected to the front of the rotating rods 3, a support frame 8 rotatably connected to the front of the rotating frame 4, a servo motor 7 fixedly connected to the outer wall of the support frame 8, a worm gear 6 fixedly connected to the output end of the servo motor 7, a worm wheel 5 meshing with the tooth end of the worm gear 6, a rotary gear disk 9 fixedly connected to the bottom of the support frame 8, and rotary gear disk 9 on its left and right sides. A first spring plate 10 is slidably connected to each of the components. A push block 11 is meshed with the tooth end of the indexing gear 9. A second spring plate 12 is slidably connected to the left side of the push block 11. A push rod 13 is fixedly connected to the front side of the second spring plate 12. A spring 14 is provided on the outer wall of the push rod 13. A pressing rod 15 is fixedly connected to the front side of the push rod 13. Multiple sliding frames 18 are fixedly connected to the bottom end of the sand table 1. A support slide 17 is slidably connected to the bottom end of the sliding frame 18. An upper bracket 16 is fixedly connected to the bottom end of the multiple support slides 17. A lifting component is provided at the bottom end of the upper bracket 16.

[0027] Specifically, the servo motor 7 is started and drives the worm gear 6 to rotate, so that the rotating frame 4 can drive the rotating rod 3 through the worm wheel 5. The rotating rod 3 pushes the sand table 1 upward through the connecting frame 2, so that the sand table 1 rotates through the sliding frame 18 and the support slide 17, which are furthest away from the rotating frame 4, thus achieving the effect of tilting the sand table 1. Pushing the pressing rod 15 backward causes the push rod 13 to rotate the indexing gear 9 by one-quarter through the push block 11, which can drive the support frame 8 to rotate, thereby changing the direction of the rotating frame 4 and the rotating rod 3. The indexing gear 9 is stabilized by two first spring plates 10, and the push block 11 contacts the outer wall of the indexing gear 9 through the second spring plate 12. The push rod 13 returns to its original position through the spring 14, so that the sand table 1 can achieve the effect of tilting in multiple directions.

[0028] Reference Figure 1 and Figure 5 The lifting assembly includes a lower support 25. Two slide rods 19 are fixedly connected to the inner wall of the lower support 25. A slider 20 is slidably connected to the outer wall of the slide rods 19. A support rod 24 is rotatably connected to the outer wall of the slider 20. One of the support rods 24 is rotatably connected to the outer wall of the upper support 16. A threaded rod 22 is rotatably connected to the inner wall of the upper support 16. A connecting rod 21 is threadedly connected to the outer wall of the threaded rod 22. A rotating handle 23 is fixedly connected to the right side of the threaded rod 22.

[0029] Specifically, by rotating the handle 23 and causing the threaded rod 22 to rotate, the connecting rod 21 can drive the sliders 20 at its front and rear ends to move on the outer wall of the slide rod 19. This allows the upper slider 20 to drive the support rod 24 that is rotatably connected to it. There are two support rods 24 at the front and rear ends that are cross-connected. Their top ends are rotatably connected to the upper bracket 16 and the slider 20, respectively, and their bottom ends are rotatably connected to the lower bracket 25 and the slider 20, respectively. This allows the four support rods 24 to drive the upper bracket 16 to move together, thereby achieving the effect of adjusting the height of the sand table 1.

[0030] Reference Figure 1 and Figure 5 The bottom end of the lower bracket 25 is fixedly connected to two fixed wheels 26, and the bottom end of the lower bracket 25 is rotatably connected to two rotating wheels 27.

[0031] Specifically, two fixed wheels 26 and a rotating wheel 27 are connected to the bottom of the lower bracket 25, which allows the sand table 1 to be moved so that its position can be easily changed.

[0032] Reference Figure 2 and Figure 3 The worm gear 5 is fixedly connected to the front side of the rotating frame 4, and the worm 6 is rotatably connected to the inner wall of the support frame 8.

[0033] Specifically, the transmission structure formed by the worm gear 5 and the worm 6 enables the rotating frame 4 to change its rotation angle through the rotation of the servo motor 7, thereby achieving the effect of tilting the sand table 1.

[0034] Reference Figures 2-3 The pressing rod 15 is slidably connected to the inner wall of one of the support slides 17, and the push rod 13 is slidably connected to the outer wall of the support slide 17; two first spring plates 10 are fixedly connected to the outer wall of the worm gear 6, and the push block 11 is rotatably connected to the outer wall of the push rod 13; the push rod 13 is slidably connected to the inner wall of the upper bracket 16, and the spring 14 is set on the outer wall of the upper bracket 16; the indexing gear 9 is rotatably connected to the top of the upper bracket 16, and the first spring plates 10 are slidably connected to the bottom of the support frame 8.

[0035] Specifically, by pressing the lever 15 and then moving the push rod 13 to compress the spring 14, the push rod 13 pushes the indexing gear 9 to rotate through the push block 11. Then, the spring force of the spring 14 allows the push block 11 to move forward and re-engage with the indexing gear 9. This makes it easier for the indexing gear 9 to drive the support frame 8 to rotate again. The two first spring plates 10 stabilize the support frame 8 and the indexing gear 9 after they rotate, thus achieving the effect of easily changing the tilt direction of the sand table 1.

[0036] Reference Figure 1 and Figure 5The connecting rod 21 is slidably connected to the bottom end of the upper bracket 16, and the two connecting rods 21 are fixedly connected to the front and rear ends of the threaded rod 22; one of the support rods 24 is rotatably connected to the outer wall of the lower bracket 25, and the upper bracket 16 is slidably connected to the outer wall of the lower bracket 25.

[0037] Specifically, through the threaded connection between the threaded rod 22 and the connecting rod 21, when the rotating handle 23 drives the threaded rod 22 to rotate, the connecting rod 21 can drive the two support rods 24 through the slider 20, so that the upper bracket 16 changes the distance between itself and the lower bracket 25 through the intersection angle of the four support rods 24, thereby achieving the effect of adjusting the height of the sand table 1.

[0038] Working principle: By pushing the sand table 1 to move it to the appropriate position, the rotating wheel 27 is rotated to make the angle of the two rotating wheels 27 offset from that of the fixed wheel 26, thus fixing the sand table 1. Then, the rotating handle 23 is rotated, causing the connecting rod 21 to move to the left through the rotation of the threaded rod 22, which in turn drives the two upper sliders 20 to move. This causes the connecting rod 21 to drive the two support rods 24 to rotate, so that the four support rods 24, together with the upper bracket 16 and the lower bracket 25, form a scissor-like structure, which can drive the upper bracket 16 to rise, thereby achieving the effect of adjusting the height of the sand table 1.

[0039] After adjusting the sand table 1 to a certain height, start the servo motor 7, which drives the rotating frame 4 to rotate via the worm gear 6 and worm wheel 5. The rotating frame 4 rotates upward and pushes the sand table 1 through the rotating rod 3 and connecting frame 2. With the support of the rear support slide 17 and sliding frame 18, the sand table 1 is tilted. If the tilt direction of the sand table 1 is not appropriate, start the servo motor 7 again to rotate in the opposite direction, so that the rotating frame 4 drives the sand table 1 to move downward and return to its original position via the rotating rod 3 and connecting frame 2. Then push the pressing rod 15, so that the push rod 13 drives the push block 11, so that the push block 11 drives the indexing gear 9 to rotate, so that the indexing gear 9 drives the support frame 8 to rotate and changes the direction of the rotating frame 4, thereby changing the tilt direction of the sand table 1.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
