Description

Technical Field

[0001] This invention relates to the field of sand table technology, and in particular to a portable simulation management sand table. Background Technology

[0002] In fields such as business simulation, teaching and training, and project planning, business simulation sandboxes serve as an intuitive and concrete visualization tool. They can transform complex business logic, spatial layout, or process relationships into operable and predictable physical models, helping users quickly understand the core logic and optimize decision-making solutions. Therefore, they are widely used in scenarios such as corporate training, college teaching, and project seminars.

[0003] However, existing simulation management sandboxes still have many problems that urgently need to be solved in actual use: Firstly, traditional sand tables are mostly fixed structures, large in size and lack effective portable design. Whether moving them between different indoor venues or transporting them to the field or to other locations for seminars, additional transportation tools are required. The handling process is cumbersome and can easily damage the sand table model, which greatly limits the flexibility of its use scenarios. Secondly, the fixing method of the sand table is singular, and most of them can only be adapted to models of specific sizes and shapes. They lack universality for simulated business scenarios of different specifications. When changing the sand table, the fixing structure needs to be readjusted, which is inconvenient and inefficient. Third, the display height of existing sand table models is mostly fixed and cannot be flexibly adjusted according to the usage scenario, resulting in some users not being able to observe clearly and having insufficient participation, which affects the effect of simulation and business development.

[0004] Therefore, a portable simulation management sandbox is needed to solve the above problems. Summary of the Invention

[0005] The main objective of this invention is to provide a portable simulation management sandbox that can effectively solve the problems mentioned above.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A portable simulation business sand table includes a cover plate and a box body. The box body has four support legs at the rear corners, a telescopic pull rod on the upper part of the box body, casters on the lower rear side of the box body and the left and right sides of the lower part of the cover plate, a placement plate in the lower part of the inner cavity of the box body, a fixing component on the upper part of the placement plate for fixing the sand table, and an adjustment component for adjusting the height of the placement plate on the rear wall of the box body and the rear of the placement plate.

[0007] Preferably, the cover plate and the box body are connected by a hinge, and both the upper and lower left sides are equipped with combination locks.

[0008] Preferably, the fixing assembly includes two support blocks installed on the upper and lower sides of the middle of the placement plate. The opposing surfaces of the two support blocks are provided with arc-shaped plates, and the opposing surfaces of the two arc-shaped plates are provided with a plurality of pressing mechanisms. The upper part of the upper arc-shaped plate is provided with a moving rod that passes through the upper support block. The inner cavity of the moving rod is provided with a screw, and the outer surface of the moving rod is provided with a spring connected to the upper arc-shaped plate.

[0009] Preferably, the upper arc-shaped plate is connected to the lower part of the moving rod, the lower arc-shaped plate is connected to the lower support block, and the upper part of the screw passes through the top of the housing.

[0010] Preferably, the extrusion mechanism includes a circular shell mounted on a horizontal plane away from the support block of the arc plate. The inner cavity of the circular shell is provided with a second spring and an extrusion rod, and the extrusion rod extends out of the horizontal plane away from the arc plate of the circular shell.

[0011] Preferably, the top front side of the cover plate has an arc-shaped hole that is movable by a screw.

[0012] Preferably, the adjustment assembly includes a bidirectional threaded rod installed on the middle side of the rear wall of the housing and guide rods provided on both the left and right sides of the rear wall of the housing. The upper part of the bidirectional threaded rod is provided with a turntable connected by a round rod. The turntable is located on the top wall of the housing. Two moving blocks are provided in the middle of the outer surface of the bidirectional threaded rod. Both of the two moving blocks are provided with connecting rods on the left and right sides. The two connecting rods on the left and right sides, which are far apart from each other, are provided with an unfolding mechanism that slides on the outer surface of the guide rod.

[0013] Preferably, the unfolding mechanism includes a slider that slides on the outer surface of the connecting rod, and a connecting plate is provided at the front of the slider and the lower part of the placement plate, with an arc-shaped rod provided between the two connecting plates.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention enables convenient single-person movement through the combination of a pull rod and omnidirectional wheels, eliminating the need for external transportation equipment. It is more flexible and efficient for both indoor site transfers and transportation in outdoor or off-site seminar scenarios. At the same time, the cover and the box form a sealed storage space after closure, effectively avoiding the drawbacks of traditional sand table transportation, which is prone to damage. This not only ensures the integrity of the sand table but also expands the scope of application scenarios for the simulated business sand table.

[0015] 2. The fixing component of the present invention uses symmetrically arranged arc plates and multiple extrusion mechanisms. By utilizing the transmission of moving rods and screws and the elastic force of springs one and two, the extrusion rod can adapt to sand table models of different sizes and shapes. Stable clamping can be achieved without readjusting the fixing structure, which greatly improves the convenience of operation and the versatility of the device, and reduces the operation cost and time cost when changing sand tables.

[0016] 3. This invention, through the adjustment of the bidirectional threaded rod, moving block, connecting rod and unfolding mechanism in the component, can drive the placement plate to rise and fall smoothly by rotating the turntable, flexibly adjusting the display height of the sand table, ensuring that users in different positions can clearly observe the details of the sand table, enhancing the sense of participation and simulation effect, effectively solving the usage limitations caused by fixed height sand tables, and further improving the practical value of simulation management sand tables.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] Example 1, as Figure 1 , Figure 2 , Figure 4 as well as Figure 6As shown, a portable simulation business sand table includes a cover plate 1 and a box body 2. The four corners of the rear of the box body 2 are provided with support feet 5. The upper part of the box body 2 is provided with a telescopic pull rod 3. The lower rear side of the box body 2 and the left and right sides of the lower part of the cover plate 1 are provided with casters 4. The lower part of the inner cavity of the box body 2 is provided with a placement plate 6. The upper part of the placement plate 6 is provided with a fixing component 7 for fixing the sand table. The rear wall of the box body 2 and the rear of the placement plate 6 are both provided with an adjustment component 8 for adjusting the height of the placement plate 6. Furthermore, the cover plate 1 and the box body 2 are connected by hinges, and both the upper and lower left sides are equipped with combination locks.

[0021] A sand table is a visual tool that simulates a real system / space in physical or digital form. Its core logic is to transform complex objects into observable, deductive, and operable models through three major features: "scaling and restoration," "element abstraction," and "dynamic interaction," for analysis, decision-making, or teaching. This device is mainly used to fix the physical simulation sand table and make it easy to carry. The physical sand table is a visualization tool that restores production lines, equipment layouts, logistics paths, and process flows through physical scale models or digital simulation technology.

[0022] The implementation process of this device is as follows: First, the staff lay the device flat on the ground so that the support leg 5 touches the ground. Then, the staff unlocks the combination lock between the cover plate 1 and the box body 2. The combination lock is the same as that used in the suitcase, and will not be described in detail in this article. Then, the staff can open the cover plate 1 and place the sand table to be displayed in front of the placement plate 6. Next, the staff will rotate the fixing component 7 to fix the sand table on the placement plate 6, ensuring that the sand table will not shake or shift. Its fixing component 7 can fix sand tables of different sizes and shapes, thereby improving the applicability of the device.

[0023] In the above process, after the sand table is placed, the staff closes the cover plate 1 and locks it with a combination lock. Then, the device can be lifted up, and the staff can pull the lever 3 to move the device through the casters 4, moving the sand table to the location where it needs to be displayed, thus realizing the transportation of the sand table and improving the practicality of the device.

[0024] The design of the cover plate 1 and the box 2 improves the convenience of carrying the sand table, allowing it to be transported without the need for a transport device.

[0025] After the sand table is moved to the desired position, the staff lays the device flat and then opens the cover 1 to display the sand table placed on the placement plate 6. If the display height needs to be adjusted, staff can rotate the adjustment component 8 to move it, lifting the placement plate 6 connected to the fixing component 7, so that the placement plate 6 is in a flat position and moves upward, thereby increasing the display height of the sand table for display.

[0026] This device is purely mechanically driven and requires no power source, making it suitable for outdoor demonstrations and enhancing its practicality.

[0027] As described above, the combination of a pull rod and omnidirectional wheels allows for convenient single-person movement without relying on external transportation equipment. This makes it more flexible and efficient for both indoor site transfers and transportation to outdoor or off-site seminar scenarios. Furthermore, the closed cover and casing create a sealed storage space, effectively avoiding the drawbacks of traditional sand table transport where damage is common. This not only ensures the integrity of the sand table but also expands the range of applications for the simulated business sand table. In Example 2, further, in order to achieve the purpose of fixing the sand table to the placement plate 6 by means of the fixing component 7, see [reference needed]. Figure 4 and Figure 5 The fixing component 7 includes two support blocks 74 installed on the upper and lower sides of the middle of the placement plate 6. The two support blocks 74 are provided with arc-shaped plates 76 on their opposite sides. The two arc-shaped plates 76 are provided with several pressing mechanisms 75 on their opposite sides. The upper part of the arc-shaped plate 76 is provided with a moving rod 71 that passes through the upper support block 74. The inner cavity of the moving rod 71 is provided with a screw 72. The outer surface of the moving rod 71 is provided with a spring 73 that is connected to the upper arc-shaped plate 76. Furthermore, the upper arc plate 76 is connected to the lower part of the moving rod 71, the lower arc plate 76 is connected to the lower support block 74, and the upper part of the screw 72 passes through the top of the box 2. Furthermore, the extrusion mechanism 75 includes a circular shell 751 installed on a horizontal plane of the arc plate 76 away from the support block 74. The inner cavity of the circular shell 751 is provided with a spring 752 and an extrusion rod 753, and the extrusion rod 753 extends out of the horizontal plane of the circular shell 751 away from the arc plate 76. Furthermore, an arc-shaped hole is provided on the front side of the top of the cover plate 1, which is moved by the screw 72.

[0028] The workflow of fixed component 7 is as follows: After the sand table is placed on the placement plate 6, the staff can rotate the screw 72. When the screw 72 rotates, through the threaded connection between the screw 72 and the moving rod 71, the moving rod 71 will slide in the inner cavity of the upper support block 74, which will drive the upper arc plate 76 and several connected extrusion mechanisms 75 to move to the other side of the arc plate 76, so that the extrusion mechanism 75 comes into contact with the sand table.

[0029] In the above, after the extrusion mechanism 75 comes into contact with the sand table, it will first push the sand table so that the sand table comes into contact with several extrusion mechanisms 75 at the bottom. Then the extrusion rod 753 will be subjected to a reaction force, slide in the inner cavity of the circular shell 751, and compress the second spring 752. Through the action of the extrusion rod 753 at the bottom, the sand table can be fixed.

[0030] The design of several compression rods 753 enables the fixing component 7 to fix sand tables of different shapes, thus improving the applicability of the device.

[0031] In the above, when the moving rod 71 slides, it will also compress the first spring 73. When the sand table needs to be removed, the staff only needs to rotate the screw 72 in the opposite direction to make the moving rod 71 move in the opposite direction of the initial position. The design of the first spring 73 can improve the stability of the moving rod 71 when it moves. At this time, the compression rod 753 will also slide back to the initial state under the action of the second spring 752, in preparation for the next fixation of the sand table.

[0032] In the above, when the adjustment component 8 drives the placement plate 6 and the fixing component 7 to move upward, the moving rod 71 will slide in the arc-shaped hole opened on the top of the cover plate 1, so that the cover plate 1 will not hinder the movement of the moving rod 71.

[0033] In the above-mentioned design of the fixing component 7, the device can adapt to sand table models of different sizes and shapes, and can achieve stable clamping without readjusting the fixing structure, which greatly improves the convenience of operation and the versatility of the device, and reduces the operation cost and time cost when changing sand table models.

[0034] Furthermore, in order to achieve the purpose of adjusting the height of the placement plate 6 by adjusting component 8, see [reference needed]. Figure 7 and Figure 8 The adjustment assembly 8 includes a bidirectional threaded rod 81 installed on the middle side of the rear wall of the housing 2 and guide rods 85 provided on both sides of the left side of the rear wall of the housing 2. The upper part of the bidirectional threaded rod 81 is provided with a turntable 82 connected by a round rod. The turntable 82 is located on the top wall of the housing 2. The middle part of the outer surface of the bidirectional threaded rod 81 is provided with two moving blocks 83. The left and right sides of the two moving blocks 83 are provided with connecting rods 84. The two connecting rods 84 located on the left and right sides are provided with an unfolding mechanism 86 that slides on the outer surface of the guide rod 85. Furthermore, the unfolding mechanism 86 includes a slider 861 that slides on the outer surface of the connecting rod 84. The front part of the slider 861 and the lower part of the placement plate 6 are both provided with connecting plates 863, and an arc-shaped rod 862 is provided between the two connecting plates 863.

[0035] The workflow of adjustment component 8 is as follows: The operator rotates the turntable 82, causing the turntable 82 to drive the bidirectional threaded rod 81 to rotate. At this time, the bidirectional threaded rod 81, through its own bidirectional thread design and the threaded connection between the moving block 83 and the bidirectional threaded rod 81, will drive the two moving blocks 83 to move away from each other. When the moving blocks 83 move, they will drive the slider 861 to slide on the outer surface of the connecting rod 84 through the connecting rod 84. At this time, the slider 861 will drive the upper arc rod 862 to move together. Due to the design that the arc rod 862 at the bottom of the placement plate 6 is fixed, when the slider 861 moves, it will drive the arc rod 862 to rotate, causing the arc rod 862 to rotate towards the vertical position when the device is lying flat. When the curved rod 862 rotates, it will lift the placement plate 6, which allows the height of the sand table to be adjusted through the placement plate 6, making the sand table easier to display.

[0036] As described above, the design of the adjustable component 8 allows for flexible adjustment of the display height of the sand table, ensuring that users in different positions can clearly observe the details of the sand table, enhancing the sense of participation and simulation effect, effectively solving the limitations of fixed-height sand tables, and further improving the practical value of the simulation management sand table.
