[0037] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0038] Referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , an embodiment of the present utility model provides a flip electronic sand table, including a base 1 and an electronic sand table body 3. The interior of the base 1 is provided with a hollow structure and its top is open. The electronic sand table body 3 rotates inside the base 1. The depth inside the base 1 is greater than half of the width of the electronic sand table body 3, which can prevent the electronic sand table body 3 from touching the components inside the base 1 when rotating. An LED display screen is installed on the top of the electronic sand table body 3, and at the same time, a power interface and a data interface are also provided on the electronic sand table body 3. The electronic sand table body 3 has been disclosed in the Chinese utility model patent with the authorization announcement number CN219510516U, so the electronic sand table body 3 belongs to the existing well-known technology and will not be elaborated too much. Heat sinks 15 are equidistantly installed at the bottom of the electronic sand table body 3. By using the heat transfer effect of the heat sinks 15, heat transfer can be carried out between the heat on the surface of the electronic sand table body 3 and the air inside the base 1, so as to achieve the heat dissipation operation of the electronic sand table body 3. Two rotating shafts 2 are rotatably arranged on the inner wall of the base 1, and the electronic sand table body 3 is installed between the two rotating shafts 2.

[0039] Two flipping components and two driving components are arranged inside the base 1. The driving components are used to cooperate with the flipping components to drive the electronic sand table body 3 to flip and tilt and rotate 180 degrees. By using the cooperation of the flipping components and the driving components, the flipping adjustment of the electronic sand table body 3 can be realized. On the one hand, the tilting angle of the electronic sand table body 3 can be adjusted for convenient viewing. On the other hand, the electronic sand table body 3 can be driven to flip 180 degrees, so that the LED screen on its top can be flipped and stored inside the base 1, thereby protecting it from being damaged by bumping when not in use, and at the same time avoiding dust contamination when not in use, which is beneficial to actual application and operation. An exhaust component is also arranged inside the base 1.

The rack 5 is installed on the limit bar 7, and the cooperation between the limit groove 6 and the limit bar 7 makes the lateral movement of the rack 5 more stable. The mounting groove 8 is provided on the inner wall of the base 1 and is located on one side of the limit groove 6. The servo electric cylinder 9 is installed inside the mounting groove 8. The mounting groove 8 is used to better install the servo electric cylinder 9. The servo electric cylinder 9 is a modular product that integrates a servo motor and a lead screw, and belongs to the existing well-known technology, so it will not be described in detail. The piston rod of the servo electric cylinder 9 is fixedly connected to one end of the rack 5. The operation of the servo electric cylinder 9 can push the rack 5 to move laterally under the limiting action between the limiting groove 6 and the limiting bar 7, thereby better realizing the power transmission operation.

The exhaust groove 10 is opened on one side of the base 1, and the exhaust fan 11 is installed inside the exhaust groove 10 (the exhaust fan 11 is installed inside the exhaust groove 10 through a mounting frame, which is a well-known existing setting, so the specific structure of the mounting frame is not shown in the figure). Maintenance doors 12 are rotatably connected to both sides of the base 1 at equal intervals. The maintenance doors 12 can be used to facilitate the maintenance of the components inside the base 1. Heat dissipation grooves 13 are opened on the maintenance doors 12. The heat dissipation grooves 13 can cooperate with the exhaust groove 10 to form a heat dissipation air duct. Filter nets are arranged inside the heat dissipation grooves 13. The filter nets can prevent dust from entering the inside of the base 1 through the heat dissipation grooves 13. A filter plate 14 is installed inside the exhaust groove 10. Filter net holes are arranged at equal intervals on the filter plate 14. The filter plate 14 can prevent dust from entering the inside of the base 1 through the exhaust groove 10.

[0043] Referring to Figure 1 and Figure 2 , in one aspect of this embodiment, a control panel 16 is installed on the top of the base 1. The servo electric cylinder 9 and the exhaust fan 11 are both electrically connected to the control panel 16. The control panel 16 can be used to better control the operation of the servo electric cylinder 9 and the exhaust fan 11.

[0044] Working principle:

[0045] During use, first power on the device, then connect the power interface and data interface on the electronic sand table body 3 to the corresponding devices respectively, and then the electronic sand table body 3 can be used;

[0046] When it is necessary to adjust the tilt angle of the electronic sand table body 3, control the servo electric cylinder 9 to work through the control panel 16, which can push the rack 5 to move horizontally under the limiting action of the limiting groove 6 and the limiting strip 7. By the horizontal movement of the rack 5, the gear 4 can be driven to rotate, thereby driving the rotating shaft 2 connected to the gear 4 to rotate. By the rotation of the rotating shaft 2, the electronic sand table body 3 fixed thereto can be driven to rotate, so as to adjust the tilt angle of the electronic sand table body 3, as Figure 2 shown;

[0047] When the electronic sand table body 3 is not needed to be used, control the electronic sand table body 3 to flip 180 degrees through the above operations, as Figure 3 shown, so that the LED screen on its top can be flipped and stored inside the base 1, thereby protecting it from being damaged by bumps when not in use, and at the same time avoiding dust contamination when not in use, which is beneficial to actual application and operation.

[0048] In addition, during use, the exhaust fan 11 can be controlled through the control panel 16 to operate, discharging the hot air generated inside the base 1 during operation to the outside of the device through the exhaust slot 10. At the same time, due to the effect of negative pressure, the outside cold air enters the inside of the base 1 through the heat dissipation slots 13 on the maintenance door 12, thereby realizing the heat dissipation operation. Meanwhile, by utilizing the heat transfer effect of the heat sink 15 at the bottom of the electronic sand table body 3, the heat on the surface of the electronic sand table body 3 and the air inside the base 1 can be heat-transferred, thereby achieving the heat dissipation operation of the electronic sand table body 3, ensuring the overall heat dissipation effect of the device, and further avoiding the situation of damage to the device caused by poor heat dissipation, effectively extending the service life of the device.
