Abstract
Description
Technical Field
[0001] This utility model relates to a sand table model, specifically a height-adjustable, layered sand table structure. Background Technology
[0002] A sand table model is a device that enlarges or reduces a building or equipment to a certain scale for research. Researchers complete corresponding work through experiments by studying and understanding the sand table, while allowing staff and visitors to intuitively understand the designer's intentions and concepts.
[0003] However, existing sand table structures typically only have one level in practical use, which cannot display more of the corresponding structures or different scenes. If a specific structure or scene in the sand table needs to be further displayed, a separate sand table needs to be set up, thus requiring additional installation space and increasing the footprint of the sand table setup. Therefore, it is necessary to propose a liftable, layered sand table structure to solve the aforementioned problems. Utility Model Content
[0004] To address the shortcomings of existing sand table technologies, which have only one layer and require additional sand table units to be added for specific structures or scenes, thus increasing the overall footprint, this invention provides a height-adjustable, layered sand table structure.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] This utility model discloses a height-adjustable, layered sand table structure, including a limiting rod. The limiting rod has a second sliding groove inside, and a limiting ring is slidably connected inside the second sliding groove. A first protrusion is fixedly connected inside the limiting ring, and a second handle is fixedly connected to one end of the first protrusion. A first spring is fixedly connected to one side of the limiting ring, and the inside of the first spring is movably sleeved on the surface of the first protrusion. A locking rod is engaged with the outer surface of the first protrusion, and a first limiting block is fixedly connected to the outer surface of the locking rod. A first sand table is rotatably connected to one side of the first limiting block. A second limiting block is fixedly connected to the middle position of the locking rod, and a second sand table is rotatably connected to one side of the second limiting block. A limiting post is rotatably connected inside the locking rod. The first limiting block has a first sliding groove inside, and a second protrusion is slidably connected to the inner wall of the first sliding groove. A first handle is fixedly connected to the outer surface of the second protrusion, and a second spring is fixedly connected to one end of the second protrusion. The other end of the second spring is fixedly connected to the inside of the first limiting block, and the outer surface of the second protrusion engages with the inside of the first sand table.
[0007] As a preferred embodiment of this utility model, a slider is fixedly connected to the end of the limiting post away from the second sand table, and a support frame is fixedly connected to the lower surface of the limiting rod.
[0008] As a preferred embodiment of this utility model, a second motor is fixedly connected to the inner bottom wall of the support frame, and a threaded column is fixedly connected to the output end of the second motor. The outer surface of the threaded column is threadedly connected to the inner wall of the slider.
[0009] As a preferred embodiment of this utility model, the limiting rod has a third sliding groove inside, and the inner wall of the third sliding groove is slidably connected to the outer surface of the slider.
[0010] As a preferred embodiment of this utility model, a first motor is fixedly connected to the upper surface of the support frame, a support block is fixedly connected to the upper surface of the support frame, and a bidirectional threaded rod is fixedly connected to the output end of the first motor.
[0011] As a preferred embodiment of this utility model, the outer surface of the bidirectional threaded rod is threadedly connected to a first connecting block, and the interior of the first connecting block is rotatably connected to a first connecting rod.
[0012] As a preferred embodiment of this utility model, the end of the first connecting rod away from the first connecting block is rotatably connected to a support plate, and the upper surface of the support plate is rotatably connected to a second connecting rod.
[0013] As a preferred technical solution of this utility model, the end of the second connecting rod away from the support plate is rotatably connected to a second connecting block, and the interior of the second connecting block is threadedly connected to the outer surface of the bidirectional threaded rod.
[0014] The beneficial effects of this utility model are as follows: When the sand table needs to be changed, pulling the second handle causes the limiting ring to slide inside the second groove, compressing the first spring. The first protrusion separates from the locking rod, releasing the restriction of the locking rod by the first protrusion. At the same time, pulling the first handle causes the second protrusion to slide inside the first limiting block, compressing the second spring and releasing the restriction of the first sand table by the second protrusion. This allows the first sand table, locking rod, etc., to rotate around the limiting post. When the lower sand table reaches the top, the second handle and the first handle are released, allowing the second handle and the first handle to limit the device, thus enabling the sand table to be changed to the bottom. This allows for the display of different sand tables, showcasing more structures and scenes. Attached Figure Description

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0025] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, this utility model discloses a height-adjustable, layered sand table structure, including a limiting rod 6. A second sliding groove 19 is formed inside the limiting rod 6. A limiting ring 16 is slidably connected inside the second sliding groove 19. A first protrusion 15 is fixedly connected inside the limiting ring 16. A second handle 4 is fixedly connected to one end of the first protrusion 15. A first spring 18 is fixedly connected to one side of the limiting ring 16. The inside of the first spring 18 is movably sleeved on the surface of the first protrusion 15. A locking rod 17 is engaged with the outer surface of the first protrusion 15. A first limiting block 3 is fixedly connected to the outer surface of the locking rod 17. A first limiting block 3 is fixedly connected to one side of the first limiting block 3. A first sand table 5 is rotatably connected. A second limiting block 8 is fixedly connected to the middle position of the locking rod 17. A second sand table 7 is rotatably connected to one side of the second limiting block 8. A limiting post 21 is rotatably connected inside the locking rod 17. A first sliding groove 2 is opened inside the first limiting block 3. A second protrusion 28 is slidably connected to the inner wall of the first sliding groove 2. A first handle 1 is fixedly connected to the outer surface of the second protrusion 28. A second spring 29 is fixedly connected to one end of the second protrusion 28. The other end of the second spring 29 is fixedly connected to the inside of the first limiting block 3. The outer surface of the second protrusion 28 is locked to the inside of the first sand table 5.
[0026] During operation, when it is necessary to change the sand table, start the second motor 24 to raise the height of the slider 20, thereby raising the height of the locking rod 17 and raising the height of all sand tables. Then, pull the second handle 4 to make the limiting ring 16 slide inside the second slide groove 19, compressing the first spring 18. The first protrusion 15 separates from the locking rod 17, releasing the restriction of the locking rod 17 by the first protrusion 15. At the same time, pull the first handle 1 to make the second protrusion 28 slide inside the first limiting block 3, compressing the second spring 29 and releasing the restriction of the first sand table 5 by the second protrusion 28. This allows the first sand table 5, locking rod 17, etc., to rotate around the limiting post 21. When the lower sand table reaches the top, release the second handle 4 and the first handle 1 to limit the device, thus realizing the function of changing the sand table to the bottom.
[0027] A slider 20 is fixedly connected to the end of the limiting post 21 away from the second sand table 7. A support frame 9 is fixedly connected to the lower surface of the limiting rod 6. A second motor 24 is fixedly connected to the inner bottom wall of the support frame 9. A threaded post 22 is fixedly connected to the output end of the second motor 24. The outer surface of the threaded post 22 is threadedly connected to the inner wall of the slider 20. A third sliding groove 23 is opened inside the limiting rod 6. The inner wall of the third sliding groove 23 is slidably connected to the outer surface of the slider 20.
[0028] During operation, the second motor 24 is started, driving the threaded column 22 to rotate. The slider 20 slides upward inside the limit rod 6 under the threaded transmission of the threaded column 22, driving the locking rod 17 to move upward, so that the sand table moves upward and plays the role of adjusting the height of the sand table.
[0029] A first motor 10 is fixedly connected to the upper surface of the support frame 9, and a support block 11 is fixedly connected to the upper surface of the support frame 9. A bidirectional threaded rod 26 is fixedly connected to the output end of the first motor 10. A first connecting block 12 is threadedly connected to the outer surface of the bidirectional threaded rod 26. A first connecting rod 25 is rotatably connected to the inside of the first connecting block 12. A support plate 13 is rotatably connected to the end of the first connecting rod 25 away from the first connecting block 12. A second connecting rod 27 is rotatably connected to the upper surface of the support plate 13. A second connecting block 14 is rotatably connected to the end of the second connecting rod 27 away from the support plate 13. The inside of the second connecting block 14 is threadedly connected to the outer surface of the bidirectional threaded rod 26.
[0030] During operation, the first motor 10 is started, which drives the bidirectional threaded rod 26 to rotate. Through the threaded transmission, the first connecting block 12 and the second connecting block 14 move towards the center. At this time, the first connecting rod 25 and the second connecting rod 27 rotate and gradually become vertical. The support plate 13 gradually moves closer to the ground until it is in close contact with the ground, thus supporting the ground and preventing the device from moving.
[0031] During operation, starting the first motor 10 drives the bidirectional threaded rod 26 to rotate. Utilizing the threaded transmission, the first connecting block 12 and the second connecting block 14 move towards the center. At this time, the first connecting rod 25 and the second connecting rod 27 rotate, gradually becoming more vertical. The support plate 13 gradually moves closer to the ground until it is in close contact with the ground, supporting the ground and preventing the device from moving. When the sand table needs to be changed, pulling the second handle 4 causes the limiting ring 16 to slide inside the second slide groove 19, compressing the first spring 18. The first protrusion 15 separates from the locking rod 17, releasing the restriction of the locking rod 17 by the first protrusion 15. Simultaneously, pulling the first handle 1 causes the second protrusion 2... 8 slides inside the first limiting block 3, compressing the second spring 29, causing the second protrusion 28 to release the restriction on the first sand table 5, allowing the first sand table 5, the locking rod 17, etc. to rotate around the limiting post 21. When the lower sand table reaches the top, the second handle 4 and the first handle 1 are released, allowing the second handle 4 and the first handle 1 to limit the device, realizing the function of changing the sand table to the bottom and changing different sand tables. The second motor 24 is started, driving the threaded post 22 to rotate. The slider 20 slides upward inside the limiting rod 6 under the threaded transmission of the threaded post 22, driving the locking rod 17 to move upward, causing the sand table to move upward, thus adjusting the height of the sand table.
[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
