[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application embodiment discloses a detachable model sand table. Figure 1A detachable model sand table includes a plate-shaped bottom plate 1, and a plurality of rod-shaped support rods 2 are fixedly connected to the upper surface of the bottom plate 1, and rod-shaped sliding rods 3 are slidably connected to the inner walls of the plurality of support rods 2, and the plurality of sliding rods 3 are fixedly connected to the lower surface of a box-shaped support seat 4, and a spiral column 8 is rotatably connected to the upper surface of the bottom plate 1, and a sleeve 9 is screwed and connected to the outer surface of the spiral column 8 through a ball screw, and the sleeve 9 is fixedly connected to the lower surface of the support seat 4, so that when the height of the sand table 6 needs to be adjusted according to viewing requirements, the spiral column 8 is driven to rotate by driving the worm gear 10, so that the sleeve 9 is driven to drive the support seat 4 under the action of the ball screw. The support base 4 is provided with a first connecting plate 5 on both sides of the support base 4, and a box-shaped sand table 6 is connected to the inner wall of the first connecting plate 5, and a second connecting plate 7 is fixedly connected to the two side surfaces of the sand table 6, and the two second connecting plates 7 are connected to the two first connecting plates 5 by snapping, so that the second connecting plates 7 and the sand table 6 can be quickly and stably installed by snapping the second connecting plates 7 to the first connecting plates 5, so that the sand table 6 can be quickly disassembled later, so as to facilitate the adjustment and repair of the model in the sand table 6 or the replacement of the sand table 6;

[0021] A worm wheel 10 is fixedly connected to the outer surface of the spiral column 8, and two plate-shaped support plates 11 are fixedly connected to the side edges of the spiral column 8 on the upper surface of the base plate 1. A worm 12 is rotatably connected to the side surfaces of the two support plates 11 via a rotating shaft. One end of the rotating shaft penetrates the support plate 11 to its side surface and is fixedly connected to the output end of the motor. The outer surface of the worm 12 is meshed with the outer surface of the worm wheel 10 so that the worm 12 can be driven to rotate by the motor driving the rotating shaft, thereby driving the worm wheel 10 to rotate under the meshing action of the worm 12 and the outer surface of the worm wheel 10, thereby driving the spiral column 8 to rotate, and then driving the sleeve 9 under the action of the ball screw to drive the support seat 4 and the sand table 6 to move up and down, thereby completing the height adjustment of the sand table 6.

[0022] Reference Figure 2 and Figure 3A square groove-shaped card slot 13 is provided on the upper surface of the second connecting plate 7, and a square groove-shaped through groove 14 is provided on the upper surface of the second connecting plate 7, and the through groove 14 and the card slot 13 are perpendicular to each other in the horizontal direction. Next, a connecting block 15 is slidably connected to the lower surface of the first connecting plate 5, and a rectangular block 16 is fixedly connected to the upper end of the connecting block 15, and the block 16 can be engaged with the inner wall of the card slot 13. A spring 17 is fixedly connected to the lower surface of the first connecting plate 5, and the spring 17 is located outside the connecting block 15, and the spring 17 is located outside the connecting block 15. The lower end of 17 is in contact with the connecting block 15, so that when the sand table 6 needs to be disassembled, the connecting block 15 is pressed upward to make the card block 16 leave the inner wall of the card slot 13. At this time, the spring 17 is in a compressed state, and then the connecting block 15 is rotated 90°. Then, the connecting block 15 drives the card block 16 to move downward under the resetting action of the spring 17, so that the card block 16 passes through the inner wall of the through slot 14 and is placed on the upper surface of the first connecting plate 5, so that the staff can move the sand table 6 and the second connecting plate 7 upward to disassemble the sand table 6.

[0023] The implementation principle of a detachable model sand table in the embodiment of the present application is as follows: when the height of the sand table 6 needs to be adjusted according to viewing requirements, the motor drives the rotating shaft to drive the worm 12 to rotate, thereby driving the worm wheel 10 to rotate under the meshing action of the worm 12 and the outer surface of the worm wheel 10, thereby driving the spiral column 8 to rotate, and then driving the sleeve 9 to drive the support seat 4 to move up and down under the action of the ball screw, thereby driving the sand table 6 to move up and down to complete the adjustment of the height of the sand table 6. Secondly, when the sand table 6 or the model in the sand table 6 is damaged, the working The personnel presses the connecting block 15 upwards to make the card block 16 leave the inner wall of the card slot 13. At this time, the spring 17 is in a compressed state. The connecting block 15 is then rotated 90°. Then, the connecting block 15 drives the card block 16 to move downward under the resetting action of the spring 17, so that the card block 16 passes through the inner wall of the through slot 14 and is placed on the upper surface of the first connecting plate 5, so that the staff can move the sand table 6 and the second connecting plate 7 upwards to disassemble the sand table 6, so as to adjust and repair the model in the sand table 6 or replace the sand table 6.
