[0040] Motors 3 are fixedly installed on both sides of the lower surface of the storage frame 1, and the output end of the motor 3 is connected to the end of the first adjusting screw 202 extending through the storage frame 1, and the middle of the upper surface of the assembly frame 2 is spirally penetrated and inserted with a second adjusting screw 4, and the middle of the lower surface of the assembly frame 2 is fixedly installed with a motor 5, the motor 5 is matched and aligned with the storage groove 104, and the output end of the motor 5 is connected to the end of the second adjusting screw 4 extending through the assembly frame 2, and the lower part of the outer surface of the second adjusting screw 4 is spirally sleeved and movably installed with an active ear 401, and the side of the outer surface of the active ear 401 that is close to each other is convex;

[0041] By starting the motor 3, the first adjusting screw 202 can be controlled to rotate clockwise or counterclockwise. The clockwise rotation of the first adjusting screw 202 can control the connecting ear 201 to spirally rise, so that the spiral rise of the connecting ear 201 can be used to push the assembly frame 2 to rise. At this time, during the rising process of the assembly frame 2, the main display plate 7 and the supplementary plate 6 can be driven to rise synchronously from the storage frame 1 to the outside. By starting the motor 5, the second adjusting screw 4 can be controlled to rotate clockwise or counterclockwise. The clockwise rotation of the second adjusting screw 4 can control the active ear 401 to spirally rise, so that the supplementary plate 6 can be driven to rise by the spiral rise of the active ear 401, so as to ensure that the supplementary plate 6 can be combined and aligned with the main display plate 7 during the display process.

[0042] The outer surfaces of the motor 3 and the motor 5 are both sleeved with fixed sleeves, the fixed sleeve sleeved on the outer surface of the motor 3 is fixedly connected to the lower surface of the storage frame 1, and the fixed sleeve sleeved on the outer surface of the motor 5 is connected to the lower surface of the assembly frame 2;

[0043] The motor 3 and the motor 5 can be installed, supported and fixed by the fixing sleeve to ensure the stability of the motor 3 and the motor 5 during operation.

[0044] A supplementary tray 6 is placed on the upper surface of the protruding part of the movable ear 401. Positioning pins 601 are protruding from the middle of both sides of the lower surface of the supplementary tray 6. The other end of the positioning pin 601 passes through the movable ear 401 and extends outward. The upper surfaces of the support rods 204 on both sides are movably mounted with main display trays 7. Both ends of the lower surfaces of the two groups of main display trays 7 are fixed with guide rails 701. The ends of the support rods 204 connected to the main display tray 7 are movably mounted on the inner surface of the guide rails 701.

[0045] The positioning pins 601 arranged on the lower surface of the supplementary tray 6 can ensure the stability of the connection between the supplementary tray 6 and the movable ear 401. When the display area of ​​the sand table model is large, the supplementary tray 6 and the two groups of main display trays 7 can form a sand table model. When the display area of ​​the sand table model is small, the two groups of main display trays 7 can form a sand table model. Through the offset sliding of the guide rails 701 and the support rods 204, the two groups of main display trays 7 can be stretched and expanded toward directions away from each other on both sides, so as to leave a gap for filling the sand table with the supplementary tray 6.

[0046] A sand table display method, characterized in that it comprises the following steps:

[0047] Step 1: by setting a sand table model on the upper surface of the main display tray 7 and the supplementary tray 6, the sand table model set on the upper surface of the main display tray 7 and the supplementary tray 6 is a combined model;

[0048] Step 2: By storing the supplementary tray 6 in the storage frame 1, the two sets of main display trays 7 are in a combined state, thereby reducing the space occupied by the supplementary tray 6 and the main display tray 7;

[0049] Step 3: During display, the motor 3 is started to control the assembly rack 2 to move up and down by using the cooperation between the first adjusting screw 202 and the connecting ear 201, and the main display tray 7 and the supplementary tray 6 are pushed to move toward the top of the storage frame 1 by the rising of the assembly rack 2;

[0050] Step 4: When the main display tray 7 is moved to the outside of the storage frame 1, the two sets of main display trays 7 are stretched toward two sides away from each other through the cooperation of the guide rail 701 and the support rod 204, and the sides of the outer surfaces of the two sets of main display trays 7 that are close to each other will be spaced apart;

[0051] Step 5: The motor 5 is started and the movable ear 401 is controlled by the second adjusting screw 4 to push the supplementary tray 6 toward the spaced portion between the two sets of main display trays 7 on the adjacent side and insert the supplementary tray 6 into the sand table models set on the upper surfaces of the two sets of main display trays 7 to complete the combined display;

[0052] Step 6: The reader 106 is inserted into a hard disk to read the data in the hard disk and transmit it to the projector 105. The projector 105 receives the hard disk data and projects the information onto the sand table model for mutual verification.

[0053] When the present invention is used, the sand table can be set according to the display area of ​​the sand table model. If the display area of ​​the current sand table model is large, the sand table model is divided into three parts, wherein the two groups of main display trays 7 are respectively set as the display contents on both sides of the sand table model, and the supplementary tray 6 is set as the display contents in the middle of the sand table model. If the display area of ​​the current sand table model is small, the sand table model is divided into two parts, wherein the two groups of main display trays 7 each occupy a part of the display contents;

[0054] During the display process, if the display area of ​​the current sand table model is large, the motor 3 is started to control the first adjusting screw 202 to rotate clockwise, and the connecting ear 201 is controlled to spirally rise by the clockwise rotation of the first adjusting screw 202, thereby pushing the assembly frame 2 to rise, and the assembly frame 2 is used to rise to drive the main display plate 7 and the supplementary plate 6 to rise synchronously from the storage frame 1 to the outside. At this time, the motor 5 is started to control the second adjusting screw 4 to rotate clockwise, and the movable ear 401 can be controlled to spirally rise by the clockwise rotation of the second adjusting screw 4, thereby driving the supplementary plate 6 to rise. In this case, the two groups of main display plates 7 extending outside the storage frame 1 can be stretched toward the two sides away from each other, thereby vacating the middle interval of the sand table model. At this time, with the rise of the supplementary plate 6, the filling of the middle interval of the sand table model can be completed, and the combined display of the entire sand table model is completed;

[0055] Secondly, the hard disk carrying the sand table model display data can be electrically connected to the reader 106, and the reader 106 is used to read the sand table model display data and transmit it to the projector 105 for projection display on the sand table model, further supplementing the display effect of the sand table model;

[0056] When the sand table model display is completed, the motor 5 can be started to control the second adjusting screw 4 to rotate counterclockwise, thereby controlling the active ear 401 to spirally descend and drive the supplementary tray 6 to sink toward the storage frame 1. After the supplementary tray 6 sinks, the middle interval between the two groups of main display trays 7 can be vacated again. At this time, the two groups of main display trays 7 can be pushed to close together. In this case, the motor 3 can be started to control the first adjusting screw 202 to rotate counterclockwise, thereby controlling the connecting ear 201 to spirally descend and drive the assembly frame 2 to sink toward the storage frame 1. At this time, the sinking of the assembly frame 2 can drive the supplementary tray 6 and the main display tray 7 to sink toward the storage frame 1, completing the division, folding and storage of the sand table model, and reducing the space occupied by the sand table model when not in use.

[0057] The above are only embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
