Description
Technical Field
[0001] This utility model relates to the field of teaching sand table technology, specifically a detachable remote sensing demonstration sand table device suitable for teaching scenarios. Background Technology
[0002] Traditional teaching methods often employ an integrated structural design, fixing the remote sensing display module to a supporting frame. While this allows for the display of basic remote sensing content, the fixed angle creates blind spots for students in the back or side seats in multi-person teaching scenarios, preventing them from clearly obtaining spatial information from the sand table and limiting the coverage of the teaching demonstration. Furthermore, the fixed structure is bulky and heavy, making it difficult to move flexibly between classrooms. When teaching activities need to be conducted across different locations, significant manpower is required for overall relocation, which is not only inefficient but also carries the risk of collision damage. Therefore, those skilled in the art have provided a detachable remote sensing demonstration sand table device suitable for teaching scenarios to solve the problems mentioned in the background art. Utility Model Content
[0003] The purpose of this invention is to provide a detachable remote sensing demonstration sand table device suitable for teaching scenarios, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: A detachable remote sensing demonstration sand table device suitable for teaching scenarios includes a U-shaped base plate. The U-shaped base plate has a fixed shaft rotatably connected to its inner sidewall. A pair of support rods are fixedly connected to the surface of the fixed shaft. A connecting component is provided at the upper end of the support rods, and the support rods are connected to a tray through this connecting component. A remote sensing electronic sand table is provided on the tray.
[0005] Furthermore, the connecting assembly includes a second rotating block and a first fixed rod. The second rotating block is fixedly connected to both support rods, and the first fixed rod is rotatably connected through and rotatably connected to the second rotating block.
[0006] Furthermore, the connecting assembly also includes a connecting block and a fixing block. The first fixing rod is fixedly connected to both ends of the connecting block, and a pair of fixing blocks are fixedly connected to the lower surface of the support plate. The connecting block is provided with a groove for cooperating with the fixing block, and the fixing block is inserted into the connecting block through this groove.
[0007] Furthermore, the support rod and the tray are also provided with an adjustment assembly, which includes a first rotating block, an adjustment rod and a second fixed rod. A pair of first rotating blocks are fixedly connected to the lower surface of the tray, and a second fixed rod is fixedly connected between the two first rotating blocks. An adjustment rod is rotatably connected to the surface of the second fixed rod.
[0008] Furthermore, the adjustment assembly also includes a tilt adjustment groove, an elevation adjustment groove, and a locking rod. The adjustment rod has a set of tilt adjustment grooves, and the support rod has a set of elevation adjustment grooves. The tilt adjustment grooves and elevation adjustment grooves have the same diameter, and a locking rod is inserted into one of the tilt adjustment grooves and one of the elevation adjustment grooves.
[0009] Furthermore, a pair of anti-detachment plates are fixedly connected to the U-shaped base plate, and a U-shaped plug plate is inserted into the anti-detachment plate, with the inner side wall of the U-shaped plug plate abutting against the support rod.
[0010] Furthermore, a pair of first snap-fit plates are fixedly connected to one end of the tray, and a pair of second snap-fit plates are fixedly connected to the other end of the tray, with the remote sensing electronic sand table snapped between the first snap-fit plates and the second snap-fit plates.
[0011] By adopting the above technical solution Compared with the prior art, the beneficial effects of this utility model are: 1. This device is specifically designed for teaching scenarios. Its core is a remote sensing electronic sand table, which can concretize abstract remote sensing technology principles, geospatial information, and other content. At the same time, the angle of the remote sensing electronic sand table can be flexibly adjusted by the adjustment components. By changing the docking position of the downward adjustment slot and the upward adjustment slot, and then inserting the locking rod for fixation, it can not only meet the needs of teachers for the sand table display angle in different teaching stages (such as theoretical explanation, case analysis, and practical demonstration), but also allow students in different seats to clearly observe the sand table content. It effectively solves the problem of blind spots in traditional fixed-angle demonstration devices and significantly improves the intuitiveness and interactivity of teaching demonstrations. 2. The device adopts a multi-component detachable connection structure. The support rod and the tray are detachably assembled through connecting components. The connecting block is inserted into the fixing block through a slot, allowing for assembly and disassembly without complicated tools. The tray and support rod can then be separated by removing the snap-fit rod. This design facilitates handling and movement in teaching scenarios. For example, when the device is shared by multiple classrooms, it can be easily transported after being disassembled, avoiding the inconvenience and risk of damage during overall transport. On the other hand, it significantly saves storage space. The support rod can be rotated and folded by removing the U-shaped snap-fit plate, making it easy to store. This makes it suitable for scenarios with limited teaching space, eliminating the need for a large storage area and reducing space and labor costs during the use of the device. 3. The connection structure of each component of the device balances flexibility and stability. The U-shaped base plate provides a stable support foundation for the whole. The cooperation between the anti-detachment plate and the U-shaped plug plate can limit and fix the support rod to prevent it from shaking randomly during the demonstration. In the adjustment component, after the snap-fit rod is inserted into the docking downward adjustment slot and upward adjustment slot, it can firmly lock the adjustment angle of the remote sensing electronic sand table and avoid the teaching effect being affected by the angle deviation during the demonstration. The first snap-fit plate and the second snap-fit plate on the tray can form a bidirectional snap-fit fixation for the remote sensing electronic sand table to prevent the sand table from slipping after the angle is adjusted.

In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0014] Please see Figures 1-4This utility model provides an embodiment of a detachable remote sensing demonstration sand table device suitable for teaching scenarios, including a U-shaped base plate 4. The U-shaped base plate 4 has a fixed shaft 15 rotatably connected to its inner sidewall. A pair of support rods 5 are fixedly connected to the surface of the fixed shaft 15. A connecting component is provided at the upper end of each support rod 5, and a support plate 3 is connected to the support rod 5 through this connecting component. A remote sensing electronic sand table 1 is mounted on the support plate 3. First, the U-shaped base plate is placed stably in the teaching demonstration area. As the overall support foundation, the U-shaped base plate must be placed on a flat surface to avoid shaking during subsequent demonstrations. Then, two support rods 5 are taken, and the lower end of each support rod 5 is aligned with a pre-set rotation connection point on the inner sidewall of the U-shaped base plate. The fixed shaft 15 enables the rotational connection between the support rod 5 and the U-shaped base plate—the fixed shaft 15 passes through the sidewall of the U-shaped base plate and the lower end of the support rod 5, and the two are in a rotational fit. At this time, the support rod 5 can rotate around the fixed shaft 15 within the inner range of the U-shaped base plate.
[0015] In this embodiment, the connecting assembly includes a second rotating block 11 and a first fixing rod 13. The second rotating block 11 is fixedly connected to each of the two support rods 5. The first fixing rod 13 passes through and is rotatably connected to the second rotating block 11. The connecting assembly also includes a connecting block 12 and a fixing block 18. The connecting blocks 12 are fixedly connected to both ends of the first fixing rod 13. A pair of fixing blocks 18 are fixedly connected to the lower surface of the tray 3. The connecting block 12 has a groove for engaging the fixing blocks 18, and the fixing blocks 18 are inserted into the connecting block 12 through this groove. The second rotating blocks 11 are fixed to the upper ends of the two support rods 5 respectively. The first fixing rod 13 passes through both second rotating blocks 11, and the first fixing rod 13 is rotatably connected to the second rotating blocks 11, allowing the first fixing rod 13 to rotate around its own axis. Then, the tray 3 is taken out. A pair of fixing blocks 18 are pre-fixed to the lower surface of the tray 3. The fixing blocks 18 on the lower surface of the tray 3 are aligned with the connecting blocks 12 at both ends of the first fixing rod 13. The connecting block 12 has a groove that matches the size of the fixing block 18. The fixing block 18 is directly inserted into the groove of the connecting block 12 to complete the detachable assembly of the support plate 3 and the support rod 5.
[0016] In this embodiment, the support rod 5 and the tray 3 are further provided with an adjustment assembly. The adjustment assembly includes a first rotating block 6, an adjustment rod 7, and a second fixed rod 19. A pair of first rotating blocks 6 are fixedly connected to the lower surface of the tray 3, and a second fixed rod 19 is fixedly connected between the two first rotating blocks 6. The adjustment rod 7 is rotatably connected to the surface of the second fixed rod 19. The adjustment assembly also includes a downward tilt adjustment groove 8, an upward tilt adjustment groove 9, and a locking rod 14. A set of downward tilt adjustment grooves 8 is provided on the adjustment rod 7, and a set of upward tilt adjustment grooves 9 is provided on the support rod 5. The downward tilt adjustment grooves 8 and the upward tilt adjustment grooves 9 have the same diameter, and a locking rod 14 is inserted into one of the downward tilt adjustment grooves 8 and one of the upward tilt adjustment grooves 9. First, pull out the locking rod 14 from the adjustment assembly. The locking rod 14 was originally inserted into the tilt adjustment groove 8 of the adjusting rod 7 and the tilt adjustment groove 9 of the support rod 5 (the tilt adjustment groove 8 and the tilt adjustment groove 9 have the same diameter and are pre-aligned). After the locking rod 14 is pulled out, the angle fixation state of the adjusting rod 7 and the support rod 5 is released. At this time, the adjusting rod 7 can rotate around the second fixed rod 19. If the remote sensing electronic sand table 1 needs to tilt downward, the end of the support plate 3 away from the connecting component is rotated downward, which drives the adjusting rod 7 to rotate around the second fixed rod 19. At this time, the different tilt adjustment grooves 8 on the adjusting rod 7 will be offset from the lowest tilt adjustment groove 9 on the support rod 5 and the different grooves will be aligned with each other. If the remote sensing electronic sand table 1 needs to tilt upward, the adjusting rod 7 is fixed and the support plate 3 is rotated upward. Then, the fixed tilt adjustment groove 8 is offset from the different tilt adjustment grooves 9 and aligned again to achieve the tilting requirement.
[0017] In this embodiment, a pair of anti-detachment plates 17 are fixedly connected to the U-shaped base plate 4. A U-shaped insertion plate 16 is inserted into the anti-detachment plate 17, and the inner sidewall of the U-shaped insertion plate 16 abuts against the support rod 5. A pair of first snap-fit plates 2 are fixedly connected to one end of the support plate 3, and a pair of second snap-fit plates 10 are fixedly connected to the other end of the support plate 3. The remote sensing electronic sand table 1 is snapped between the first snap-fit plates 2 and the second snap-fit plates 10. A pair of first snap-fit plates 2 are pre-fixed to one end of the support plate 3, and a pair of second snap-fit plates 10 are fixed to the other end of the support plate 3. The two sides of the remote sensing electronic sand table 1 are aligned with the gap between the first snap-fit plates 2 and the gap between the second snap-fit plates 10, respectively, and pushed horizontally into the support plate 3 so that the remote sensing electronic sand table 1 is snapped between the first snap-fit plates 2 and the second snap-fit plates 10. To prevent the support rod 5 from rotating arbitrarily during the demonstration, it needs to be limited and fixed: take the U-shaped insertion plate and insert its two ends into the pair of anti-detachment plates 17 pre-set on the U-shaped base plate. After insertion, the U-shaped insertion plate... The inner wall of the U-shaped connector plate abuts against the outer walls of the two support rods 5. Through the limiting effect of the U-shaped connector plate, the rotation of the support rods 5 around the fixed axis 15 is restricted, ensuring that the overall structure remains stable during the demonstration.
[0018] After the teaching demonstration, or when the device needs to be moved to another classroom, simply pull out the remote sensing electronic sand table 1, which is connected between the first connecting plate 2 and the second connecting plate 10, horizontally to separate the sand table from the support plate 3. Separating the sand table prevents damage during transport. Removing the connecting rod 14 allows the adjusting rod 7 to detach from the support rod 5. Then, pull the support plate 3 upwards to disengage the fixing block 18 on the lower surface of the support plate 3 from the groove of the connecting block 12, thus separating the support plate 3 from the support rod 5. After separation, the support plate 3 and support rod 5 can be stored separately, reducing the space occupied by individual components. Pull out the U-shaped plug plate inside the anti-detachment plate 17. At this point, the rotation restriction of the support rod 5 is released. Rotate and fold the two support rods 5 around the fixed axis 15 towards the inside of the U-shaped base plate, so that the support rods 5 fit against the inner wall of the U-shaped base plate, significantly reducing the overall volume of the device. The separated U-shaped base plate, folded support rods 5, support plate 3, remote sensing electronic sand table 1, and U... The components, such as the plug-in board and the snap-fit rod 14, are sorted and organized. Since each component is lightweight and compact after disassembly, it can be easily carried to other classrooms without the need for large carrying tools. When storing, it only occupies the space of a small locker, which is especially suitable for schools with limited teaching space, effectively reducing space and labor costs.
[0019] This device is specifically designed for teaching scenarios. Its core component is a remote sensing electronic sand table 1, which can concretely present abstract concepts such as remote sensing technology principles and geospatial information. Simultaneously, the angle of the remote sensing electronic sand table 1 can be flexibly adjusted using adjustable components. By changing the docking position of the downward tilt adjustment slot 8 and the upward tilt adjustment slot 9, and then inserting the locking rod 14 for fixation, it can meet the needs of teachers for different sand table display angles in different teaching stages (such as theoretical explanations, case analyses, and practical demonstrations). It also allows students in different seats to clearly observe the sand table content, effectively solving the blind spot problem of traditional fixed-angle demonstration devices and significantly improving the intuitiveness and interactivity of teaching demonstrations. The device adopts a multi-component detachable connection structure. The support rod 5 and the tray 3 are detachably assembled via connecting components, and the connecting block 12 is inserted into the fixing block 18 through a slot, requiring no complex tools. After assembly and disassembly, the tray 3 and support rod 5 can be separated by removing the snap-fit rod 14. This design facilitates handling and movement in teaching settings, such as when the device is shared in multiple classrooms. It can be easily transported after disassembly, avoiding the inconvenience and risk of damage during overall transport. Furthermore, it significantly saves storage space. Removing the U-shaped connector 16 allows the support rod 5 to rotate and fold, making it easy to store. This makes it suitable for scenarios with limited teaching space, eliminating the need for a large storage area and reducing space and labor costs during device use. The connection structure of each component balances flexibility and stability. The base plate provides a stable support foundation for the whole. The anti-detachment plate 17 and the U-shaped plug plate can limit and fix the support rod 5 to prevent it from shaking randomly during the demonstration. In the adjustment assembly, after the snap-fit rod 14 is inserted into the docking downward adjustment groove 8 and upward adjustment groove 9, it can firmly lock the adjustment angle of the remote sensing electronic sand table 1 to avoid the teaching effect being affected by the angle deviation during the demonstration. The first snap-fit plate 2 and the second snap-fit plate 10 on the support plate 3 can form a two-way snap-fit fixation for the remote sensing electronic sand table 1 to prevent the sand table from slipping after the angle is adjusted.
[0020] This specification describes embodiments, but not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
