[0015] 1. This utility model proposes an interactive international trade sand table model. A rotating roller is embedded inside one side of the base, and this roller is fixedly connected to the output end of a servo motor also embedded inside the base. The servo motor drives the rotating roller to rotate. A dustproof cloth is placed over the outer surface of the rotating roller, and one end of the cloth is fixed to a fixing mechanism located at the upper end of the rotating mechanism.

[0028] A rolling roller 7 is rotatably embedded in the inner wall of one side of the base 1. A dustproof cloth 2 is rolled up on the outer surface of the rolling roller 7. A threaded rod 9 is rotatably embedded in the upper part of the inner wall of the front side of the base 1. A slide rod 14 is fixedly embedded in the upper part of the inner wall of the rear side of the base 1. A fixing mechanism 4 is movably arranged between the threaded rod 9 and the slide rod 14. The fixing mechanism 4 includes a fixing housing 403. An embedded rod 402 is rotatably embedded in one side of the midpoint of the upper end surface of the fixing housing 403.
[0029] Specifically, after four rotating rods 12 are rotatably installed on the lower end face of the sand table body 5, rotating blocks 13 can be rotatably installed on the lower end face of the four rotating rods 12. At the same time, two rotating blocks 13 on the same side of the four rotating blocks 13 can be rotatably connected through movable rods 11. After the two rotating rods 12 are threaded between the inner walls on both sides of the base 1 and rotatably embedded on the outer surface of the bidirectional screw 6, the bidirectional screw 6 can drive the movable rod 11 and the rotating rod 12 to move up and down. At the same time, after a rolling roller 7 is rotatably embedded inside one side of the base 1, a dustproof cloth 2 can be installed on the outer surface of the rolling roller 7. The dustproof cloth 2 can be extended under the drive of the fixing mechanism 4 set between the sliding rod 14 and the threaded rod 9, so as to cover the upper end face of the mold body and better protect the sand table body 5 from dust. The fixing mechanism 4 can also better fix the dustproof cloth 2.
[0030] Reference Figure 7 A fixing plate 401 is movably embedded in the bottom surface of the fixed housing 403. The fixing plate 401 is threadedly connected to the embedding rod 402 at the midpoint of one side of the upper end face of the fixing plate 401. The end of the dustproof cloth 2 away from the rolling roller 7 is embedded and fixedly installed on the upper side of the fixed housing 403.
[0031] Specifically, after the fixing plate 401 is movably embedded inside the fixed housing 403, the fixing plate 401 and the embedding rod 402, which is rotatably embedded at the midpoint of the upper end face of the fixed housing 403, can be threaded together. At the same time, after the dustproof cloth 2 is embedded in one side of the fixed housing 403, the embedding rod 402 can be rotated to drive the fixing plate 401 to clamp and fix the dustproof cloth 2, so that the fixed housing 403 can better drive the dustproof cloth 2 to extend.
[0032] Reference Figure 4 and Figure 5 The base 1 has embedded plates 10 fixedly installed on the bottom surface near the front and rear ends. Two movable rods 11 are slidably embedded on the upper sides of the two embedded plates 10 respectively. The two movable rods 11 are threaded on the outer surfaces of the bidirectional screw 6 respectively.
[0033] Specifically, after the embedded plate 10 is fixedly installed on the inner bottom surface of the base plate, the two movable rods 11 can be slidably installed on the outer surface of the two embedded rods 402 respectively. At the same time, after the movable rods 11 are threaded onto the outer surface of the bidirectional screw 6, the bidirectional screw 6 can better drive the movable plate to move and adjust. Meanwhile, the embedded rods 402 can also play an auxiliary role in moving the movable rods 11.
[0034] Reference Figure 3 and Figure 4 A servo motor 8 is embedded inside one side of the base 1 near the front end, and the output end of the servo motor 8 is fixedly located at the front end of the rolling roller 7.
[0035] Specifically, a servo motor 8 is embedded inside one side of the base 1. It can be fixedly connected to the winding roller 7 through the output end, so that the servo motor 8 can drive the winding roller 7 to rotate. The rotating winding roller 7 can better roll up or unroll the dustproof cloth 2.
[0036] Reference Figure 6 A worm gear 16 is rotatably embedded in the upper part of one side of the front end face of the base 1. A first bevel gear 17 is fixedly installed on the lower end face of the worm gear 16. A second bevel gear 18 is fixedly sleeved on the outer surface of the output end of the servo motor 8. The first bevel gear 17 and the second bevel gear 18 are meshed and connected.
[0037] Specifically, after the worm gear 16 is rotatably embedded inside one side of the base 1, a first bevel gear 17 can be fixedly installed on the lower end face of the worm gear 16. After the first bevel gear 17 and the second bevel gear 18 fixedly sleeved on the output end of the servo motor 8 are meshed and connected, the servo motor 8 can better drive the worm gear 16 to rotate.
[0038] Reference Figure 6 A worm gear 15 is fixedly sleeved on one side of the outer surface of the threaded rod 9. The worm 16 and the worm gear 15 are meshed and connected. The fixed housing 403 is threadedly sleeved on the outer surface of the threaded rod 9 at the front end and slidably sleeved on the outer surface of the slide rod 14 at the rear end.
[0039] Specifically, after the worm gear 15 is fixedly sleeved on the outer surface of the threaded rod 9 and meshed with the worm 16, the rotating worm 16 can better drive the threaded rod 9 to rotate. This allows the servo motor 8 to drive the winding roller 7 to rotate while also driving the threaded rod 9 to rotate, thus moving the fixing mechanism 4 sleeved on the outer surface of the threaded rod 9. This allows the dustproof cloth 2 to better cover the upper end of the sand table body 5.
[0040] Reference Figure 1 and Figure 2 The main body of the sand table 5 is movably embedded in the upper part of the inner surface of the base 1, and support plates 3 are fixedly installed on both sides of the lower end face of the base 1 near the front and rear ends.
[0041] Specifically, after the sand table body 5 is movably embedded in the upper part of the inner surface of the base 1, the base 1 can limit and protect the sand table body 5, effectively preventing the equipment body from tilting and swaying during lifting and moving. The support plate 3 can better support and fix the sand table.
[0042] Working Principle: During use, the user can start the servo motor 8 to drive the rolling roller 7 to rotate and roll up the dustproof cloth 2. The fixed mechanism 4 can also be moved and adjusted under the action of the servo motor 8, so that the rolling roller 7 can effectively roll up and store the dustproof cloth 2, exposing the sand table body 5. According to the usage needs, the bidirectional screw 6 can be rotated to drive the screw movable rod 11 to move and adjust. At the same time, the rotating rod 12 can be used to push the sand table body 5 to move up and down, so as to better display the sand table body 5. After use, after rotating the bidirectional screw 6 to move the sand table body 5 up and down, the servo motor 8 can be started again to release the rolled dustproof cloth 2. The servo motor 8 can also drive the screw rod 9 to rotate, so that the fixed mechanism 4 can drive the released dustproof cloth 2 to cover the sand table body 5, providing dust protection for the sand table body 5.
