Description

Technical Field

[0001] This utility model relates to the field of sand table dynamic model technology, and in particular to a magnetic replacement module for sand table dynamic models. Background Technology

[0002] In the field of sand table model applications, magnetic replacement modules for dynamic sand table models are widely used in teaching and training, commercial displays, scientific research simulations and other scenarios due to their ability to flexibly change display content and quickly adjust simulation scenes. These modules connect to the main body of the sand table through the principle of magnetic adsorption. When it is necessary to update the display information of the sand table or adjust the simulation plan, the corresponding module can be quickly replaced, which greatly improves the efficiency and scene adaptability of the sand table and has become one of the important directions for the development of modern sand table model technology.

[0003] Currently, most existing magnetic replacement modules for dynamic sand table models adopt a fixed magnetic connection method in their mechanical structure design. This involves fixing magnetic components to the sand table base and setting corresponding magnetic components at the bottom of the module, using magnetic force to attract the module to the sand table. The technical principle of this structure relies on the attraction between magnetic materials to achieve stable positioning of the module, which to a certain extent meets the needs of module replacement. At the same time, some modules adopt more complex fixing structures to ensure adsorption stability, ensuring that the module is not easily moved on the sand table and ensuring the accuracy of sand table simulation or display.

[0004] However, existing magnetic replacement modules for dynamic sand table models with fixed magnetic connections have significant drawbacks. Because the magnetic components are fixed inside the sand table, the modules are tightly attached to it. When it is necessary to remove the top module, there is a lack of effective auxiliary structures to help reduce the magnetic force between the module and the magnetic components, and there is no convenient lifting and adjustment mechanism to assist in the operation. Users often need to exert considerable force to forcibly pull the module, which is not only very inconvenient and time-consuming, but also easily damages the module and the sand table during the pulling process, affecting the integrity and service life of the sand table model. It cannot meet the need for efficient and convenient module replacement. Therefore, a magnetic replacement module for dynamic sand table models is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a magnetic replacement module for a sand table dynamic model, which aims to improve the problem that the top module cannot be easily removed in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A magnetic replacement module for a dynamic sand table model includes a sand table box, a placement platform on the top of the sand table box, a support leg fixedly connected to the bottom of the sand table box, a magnetic suction plate slidably connected inside the sand table box, and an adjustment component at the bottom of the sand table box.

[0008] The adjustment assembly includes a sliding column and a connecting column. The outer wall of the connecting column is slidably connected to the inside of the sandbox, and the outer wall of the sliding column is fixedly connected to the outer wall of the connecting column. A disassembly and assembly assembly is provided inside the connecting column. A hydraulic rod is fixedly connected to the bottom of the sandbox, and a connecting frame is fixedly connected to the output end of the hydraulic rod. A sliding plate is fixedly connected to the outer wall of the connecting frame, and a sliding groove is provided inside the sliding plate. The outer wall of the sliding column is slidably connected to the sliding groove, and a limit assembly is provided at the bottom of the sandbox.

[0009] As a further description of the above technical solution:

[0010] The limiting component includes a fixed rail, the top of which is fixedly connected to the bottom of the sandbox, and the sliding plate is slidably connected to the outer wall of the fixed rail.

[0012] The assembly / disassembly component includes a locking post, the outer wall of which is slidably connected to the inside of the connecting post.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the connecting column is slidably connected to the inside of the magnetic suction plate, and the outer wall of the clamping column is slidably connected to the inside of the magnetic suction plate.

[0015] As a further description of the above technical solution:

[0016] A transmission column is slidably connected inside the connecting column, and a knob is fixedly connected to the bottom of the transmission column.

[0017] As a further description of the above technical solution:

[0018] A turntable is fixedly connected to the top of the transmission column, and the outer wall of the turntable is rotatably connected to the inside of the connecting column. A limit groove is formed inside the connecting column.

[0019] As a further description of the above technical solution:

[0020] The turntable has a transmission groove inside and a limiting groove inside.

[0021] As a further description of the above technical solution:

[0022] One end of the locking pin is fixedly connected to a limiting disc, and the outer wall of the limiting disc is slidably connected inside the limiting groove.

[0023] As a further description of the above technical solution:

A limiting post is fixedly connected to one end of the fixed post, and the outer wall of the limiting post is slidably connected to the inside of the transmission groove.

[0027] This utility model has the following beneficial effects:

[0028] 1. In this utility model, the connecting column achieves its lifting function by activating the hydraulic rod.

When the knob is rotated, the knob drives the turntable and the limiting column, and in conjunction with the spring, the limiting column slides inside the transmission groove, thereby facilitating the disassembly and assembly of the magnetic plate and making it easy to maintain and replace. This solves the problem that existing devices require multiple tools to disassemble and assemble, making disassembly inconvenient and improving the speed of the device. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figures 1-3 This utility model provides an embodiment of a magnetic replacement module for a dynamic sand table model, including a sand table box 1, which serves as the basic load-bearing structure of the entire module, providing space for the installation and operation of other components. The sand table box 1 is typically made of high-strength engineering plastic, a material with excellent wear resistance and impact resistance, ensuring it is not easily damaged during long-term use. A placement platform 2 is provided on the top of the sand table box 1. The placement platform 2 is a wooden structure with a finely polished surface, exhibiting a smooth and flat characteristic. It is used to place various dynamic sand table models, providing a stable support platform for the models and preventing them from shaking or tilting during display, thus ensuring the stability and aesthetics of the display effect. Support legs 4 are fixedly connected to the bottom of the sand table box 1. The support legs 4 are generally made of metal alloys, such as aluminum alloy, which have the advantages of being lightweight and high-strength. The function of the support leg 4 is to support the sand table box 1, keeping it at a certain distance from the ground to prevent it from being worn or damp due to direct contact with the ground. It also facilitates the movement and transport of the sand table box 1. A magnetic suction plate 6 is slidably connected inside the sand table box 1. The magnetic suction plate 6 is composed of magnetic material and a metal substrate. The magnetic material generates a strong magnetic force to attract the sand table model on top, thus fixing the model in place. The metal substrate provides support and protection for the magnetic material, ensuring the structural stability of the magnetic suction plate 6. An adjustment component is provided at the bottom of the sand table box 1.

[0040] The adjustment assembly includes a sliding column 9 and a connecting column 11. The outer wall of the connecting column 11 is slidably connected to the inside of the sandbox 1. The connecting column 11 is made of high-strength carbon steel, which has good rigidity and toughness and can withstand a certain amount of tension and pressure. The outer wall of the sliding column 9 is fixedly connected to the outer wall of the connecting column 11. The connecting column 11 is equipped with a disassembly and assembly assembly. The bottom of the sandbox 1 is fixedly connected to a hydraulic rod 5. The output end of the hydraulic rod 5 is fixedly connected to a connecting frame 10. The outer wall of the connecting frame 10 is fixedly connected to a sliding plate 3. The sliding plate 3 has a sliding groove 8 inside. The outer wall of the sliding column 9 is slidably connected to the inside of the sliding groove 8. The bottom of the sandbox 1 is equipped with a limit assembly, which includes a fixed rail 7. The top of the fixed rail 7 is fixedly connected to the bottom of the sandbox 1. The sliding plate 3 is slidably connected to the outer wall of the fixed rail 7.

[0041] Specifically, in actual operation, when there is a need to remove the top module, the operator can activate the hydraulic rod 5. The hydraulic rod 5 starts working and retracts its output end. As the hydraulic rod 5 moves, it drives the connected connecting frame 10 to move. The movement of the connecting frame 10 plays a crucial role, further driving the sliding plate 3 to slide on the outer wall of the fixed rail 7. The fixed rail 7 plays an important limiting function here, ensuring that the sliding process of the sliding plate 3 is stable and accurate. As the sliding plate 3 slides, the internal sliding groove 8 also moves accordingly. The sliding column 9 slides inside the sliding groove 8. This relative sliding process pulls the connecting column 11 downward. The downward movement of the connecting column 11 causes the magnetic suction plate 6 to move downward inside the sandbox 1. After the magnetic suction plate 6 moves downward, the distance between it and the top module increases, thereby releasing the attraction to the top module. At this time, the top module can be removed and replaced.

[0042] Reference Figures 4-6The assembly and disassembly components include a locking post 14, which is a cylindrical metal rod, typically made of stainless steel, offering good strength and corrosion resistance. The outer wall of the locking post 14 is slidably connected to the inside of the connecting post 11, which in turn is slidably connected to the inside of the magnetic plate 6. The locking post 14 is used to secure the magnetic plate 6 to the connecting post 11 during installation, ensuring the stability of the magnetic plate 6 and preventing shaking or detachment during use. A transmission post 13 is slidably connected inside the connecting post 11. A knob 12 is fixedly connected to the bottom of the transmission post 13. The knob 12 is typically made of plastic with a non-slip texture for easy manual operation. A rotating knob is fixedly connected to the top of the transmission post 13. The outer wall of the turntable 15 is rotatably connected to the inside of the connecting column 11. The connecting column 11 has a limiting groove 20 inside. The turntable 15 has a transmission groove 22 inside. The turntable 15 has a limiting groove 21 inside. One end of the locking column 14 is fixedly connected to the limiting disc 18. The outer wall of the limiting disc 18 is slidably connected to the inside of the limiting groove 20. One side of the limiting disc 18 is fixedly connected to the fixing column 19. The outer wall of the fixing column 19 is slidably connected to the inside of the limiting groove 21. One end of the fixing column 19 is fixedly connected to the limiting column 16. The outer wall of the limiting column 16 is slidably connected to the inside of the transmission groove 22. The outer wall of the fixing column 19 is fitted with a spring 17. One end of the spring 17 is fixedly connected to the outer wall of the limiting disc 18. The other end of the spring 17 is fixedly connected to the inner wall of the limiting groove 20.

[0043] Specifically, in actual use, when a malfunction is found in the magnetic suction plate 6 or it needs to be upgraded or replaced, the operator can directly turn the knob 12. The rotation of the knob 12 will cause the connected transmission column 13 to start rotating. The rotation of the transmission column 13 will further drive the turntable 15 to rotate. As the turntable 15 rotates, the transmission groove 22 inside it will also rotate. The rotation of the transmission groove 22 plays a key driving role, pushing the internal limiting column 16. The movement of the limiting column 16 will drive the fixed column 19 to move together. At this time, the fixed column 19 is connected to the... The locking pin 14 will slide out from inside the magnetic plate 6. At the same time, the movement of the locking pin 14 will drive the limiting disc 18 to move together. The limiting disc 18 will compress the spring 17. When the locking pin 14 has completely slid out from inside the magnetic plate 6, the magnetic plate 6 can be removed for maintenance or replacement. After maintenance or replacement, put the magnetic plate 6 back in its original position and then release the knob 12. At this time, the compressed spring 17 will rebound, pushing the limiting disc 18 and the locking pin 14 to reset. The locking pin 14 will re-lock into the inside of the magnetic plate 6, thus firmly fixing the magnetic plate 6.

[0044] Working principle: When the top module needs to be removed, the hydraulic rod 5 can be activated to retract the output end, thereby driving the connecting frame 10 to move. Then, the connecting frame 10 drives the sliding plate 3 to slide on the outer wall of the fixed rail 7 to limit its movement, thereby driving the internal sliding groove 8 to move. This causes the sliding column 9 to slide inside the sliding groove 8, pulling the connecting column 11 downward, which in turn drives the magnetic suction plate 6 to move downward inside the sand box 1, releasing the attraction to the top module, thus facilitating removal and replacement.

[0045] Additionally, when the magnetic plate 6 needs to be replaced, the knob 12 can be rotated, which drives the transmission column 13 to rotate, which in turn drives the turntable 15 to rotate. The turntable 15 then drives the internal transmission groove 22 to rotate, thereby pushing the internal limiting column 16 and moving the fixing column 19. This causes the locking column 14 to slide out of the magnetic plate 6 and move the limiting disc 18, compressing the spring 17. Only then can the magnetic plate 6 be removed for maintenance or replacement. After that, the magnetic plate 6 can be put back, the knob 12 can be released, and the spring 17 will rebound to re-lock the locking column 14 inside the magnetic plate 6 for fixation.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
