[0022] 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.
[0023] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a modular splicing sand table base structure, including a base plate 1, with guide rails 2 fixedly connected to both sides of the top of the base plate 1, and a slider 3 slidably connected between the two guide rails 2. Sliding grooves 4 are opened on both sides of the bottom end of the slider 3, and limiting grooves 5 are opened on the top of the guide rails 2. Limiting holes 6 are opened on both sides of the top of the slider 3, and the limiting holes 6 communicate with the limiting grooves 5. A limiting rod 7 is inserted into the limiting hole 6, and the bottom end of the limiting rod 7 passes through the limiting groove 5.
[0024] In practice, turn the knob 8 at the top of the limiting rod 7 to turn the limiting rod 7 upward until the bottom end of the limiting rod 7 disengages from the limiting groove 5 at the top of the guide rail 2. At this point, the slider 3 can be moved. Slide the slider 3 along the guide rail 2. The sliding grooves 4 on both sides of the bottom end of the slider 3 can slide precisely along the guide rail 2. After the slider 3 is moved to the predetermined position, turn the limiting rod 7 downward until the bottom end of the limiting rod 7 passes through the limiting hole 6 of the slider 3 and is inserted into the limiting groove 5. In this way, the slider 3 is firmly fixed on the guide rail 2.
[0025] See Figure 3 The cross-sections of both the guide rail 2 and the limiting groove 5 are T-shaped, and the sizes of the guide rail 2 and the limiting groove 5 match.
[0026] In practice, since the cross-sections of the guide rail 2 and the limiting groove 5 are both T-shaped, the sliding grooves 4 opened on both sides of the bottom end of the slider 3 can slide precisely along the T-shaped guide rail 2, ensuring that the sliding process is stable and the direction is accurate.
[0027] See Figure 1 There are two sliders 3, which are respectively set at both ends of the two guide rails 2. Each slider 3 has a slot 9 on its opposite side, and each slider 3 has a handle 19 fixedly connected to its top.
[0028] In practice, when operating slider 3, slider 3 can be slid along guide rail 2 by holding handle 19 at the top of slider 3.
[0029] See Figure 3 The diameter of the limiting rod 7 is the same as the width of the limiting groove 5, and a knob 8 is fixedly connected to the top of the limiting rod 7.
[0030] In practice, the knob 8 is turned in the opposite direction to make the limiting rod 7 turn downwards until the bottom end of the limiting rod 7 passes through the limiting hole 6 of the slider 3 and is inserted into the limiting groove 5, so that the slider 3 is firmly fixed on the guide rail 2.
[0031] See Figure 2 and Figure 3 A sand table body 10 is slidably connected between two guide rails 2. The two sides of the sand table body 10 away from the guide rails 2 are engaged in the slots 9. A first locking block 11 is installed at one end of the sand table body 10, and a second locking block 12 is installed at the end of the sand table body 10 away from the first locking block 11. The first locking block 11 and the second locking block 12 are engaged with each other, and both the first locking block 11 and the second locking block 12 are made of magnets.
[0032] In practice, the sand table body 10 is placed between two guide rails 2, and the sand table body 10 is pushed so that its two sides slide along the guide rails 2 until the first locking block 11 at one end of the sand table body 10 and the second locking block 12 at the other end approach each other. Since both are made of magnets, the magnetic force will cause the first locking block 11 and the second locking block 12 to mesh tightly.
[0033] See Figure 4 Support seats 13 are installed on both sides of the bottom end of the base plate 1. The two ends of the support seats 13 are threaded with first bolts 14. The support seats 13 are connected to support legs 15 through the first bolts 14. A cavity is opened at the end of the support leg 15 away from the support seat 13. A telescopic leg 16 is slidably connected in the cavity. Multiple through holes are opened on both the support leg 15 and the telescopic leg 16. Second bolts 17 are threaded in the through holes. A universal wheel 18 is rotatably connected to the bottom end of the telescopic leg 16.
[0034] In practice, if it is necessary to adjust the overall height of the base, loosen the first bolt 14 connecting the threads at both ends of the support base 13 so that the support leg 15 can rotate relative to the support base 13. After adjusting to the appropriate angle, tighten the first bolt 14 to fix the support leg 15. If it is necessary to change the length of the support leg 15, unscrew the second bolt 17 connecting the telescopic leg 16 to the threaded hole on the support leg 15, pull the telescopic leg 16 to slide it in the cavity of the support leg 15, and after reaching the ideal length, screw the second bolt 17 into the corresponding through hole to lock the position of the telescopic leg 16. Furthermore, with the universal wheel 18 rotatably connected to the bottom of the telescopic leg 16, the base can be easily pushed when it is necessary to move it, achieving flexible transportation.
[0035] Working principle: When assembling the modular splicing sand table base and placing the sand table, first turn the knob 8 at the top of the limiting rod 7 to turn the limiting rod 7 upward until the bottom end of the limiting rod 7 disengages from the limiting groove 5 at the top of the guide rail 2. At this time, the slider 3 can be operated. Hold the handle 19 at the top of the slider 3 and slide the slider 3 along the guide rail 2. Since the cross-section of the guide rail 2 and the limiting groove 5 are both T-shaped, the sliding grooves 4 on both sides of the bottom end of the slider 3 can slide precisely along the T-shaped guide rail 2, ensuring that the sliding process is stable and the direction is accurate. After moving the slider 3 to the predetermined position, turn the knob 8 in the opposite direction to turn the limiting rod 7 downward until the bottom end of the limiting rod 7 passes through the limiting hole 6 of the slider 3 and is inserted into the limiting groove 5. In this way, the slider 3 is firmly fixed on the guide rail 2.
[0036] When installing the sand table body 10 onto the base plate 1, first slide the slider 3 away along the guide rail 2, then place the sand table body 10 between the two guide rails 2, push the sand table body 10 so that its two sides slide along the guide rail 2 until the first locking block 11 at one end of the sand table body 10 and the second locking block 12 at the other end approach each other. Since both are made of magnets, the magnetic force will cause the first locking block 11 and the second locking block 12 to mesh tightly, further strengthening the splicing between adjacent sand table bodies 10, allowing multiple sand table modules to be spliced into a complete and stable display sand table. Then slide the removed slider 3 onto the guide rail 2, so that the two sides of the sand table body 10 away from the guide rail 2 are accurately inserted into the slots 9 opened on the opposite side of the two sliders 3, realizing the connection and fixation between the sand table body 10 and the slider 3.
[0037] To adjust the overall height of the base, operate the relevant components of the support base 13, loosen the first bolt 14 connecting the threads at both ends of the support base 13, so that the support leg 15 can rotate relative to the support base 13. After adjusting to the appropriate angle, tighten the first bolt 14 to fix the support leg 15. If it is necessary to change the length of the support leg 15, unscrew the second bolt 17 that connects the telescopic leg 16 to the threaded hole on the support leg 15, pull the telescopic leg 16 to slide it in the cavity of the support leg 15, and after reaching the ideal length, screw the second bolt 17 into the corresponding through hole to lock the position of the telescopic leg 16. Furthermore, with the universal wheel 18 rotatably connected to the bottom of the telescopic leg 16, the base can be easily pushed when it needs to be moved, achieving flexible transportation. After moving to the designated position, the universal wheel 18 can stably support the base by virtue of its own rotation characteristics.
[0038] When the sand table body 10 needs to be disassembled for display purposes, repeat the reverse operation of the installation: turn the knob 8 to raise the limit rod 7, pull the handle 19 to move the slider 3 away, and release the connection with the sand table body 10; for the assembled sand table modules, pull the first and second interlocking blocks 11 and 12 to remove the individual sand table bodies 10 one by one, and complete the disassembly action, which is convenient for storage, replacement or rearrangement of the sand table.
