The second servo motor 22 is started to rotate the first lead screw 9011, which can reduce the angle between the rotating plate 10 and the lifting platform 9. At this time, the second servo motor 22 is started again to rotate the first lead screw 9011 in the opposite direction, which can increase the angle between the rotating plate 10 and the lifting platform 9.

[0037] Please see Figure 1-2 This utility model provides a new embodiment in which support columns 4 are fixedly connected to the four bottom corners of the main body 1 to support this application.

[0038] Please see Figure 1-3 This utility model provides a new embodiment in which an inner cavity 14 is symmetrically opened inside the display body 1, and a rotating door 3 is installed on the inner wall of the inner cavity 14 through a hinge. Electronic products that do not need to be displayed are placed inside the inner cavity 14.

[0039] Please see Figure 2 This utility model provides a new embodiment in which a first sealing block 36 is provided on the outer wall of the first sliding frame 6 and a second sealing block 37 is provided on the outer wall of the second sliding frame 31. Both the first sealing block 36 and the second sealing block 37 are made of rubber and are respectively attached to the first sliding frame 6 and the second sliding frame 31 with glue.

[0040] Working principle:

[0041] When electronic products need to be displayed, the staff first starts the first servo motor 8. The first servo motor 8 drives the third lead screw 16 to rotate clockwise. The rotation of the third lead screw 16 drives the third bevel gear 27 to rotate. The rotation of the third bevel gear 27 drives the fourth bevel gear 28 and the fifth bevel gear 29 to rotate. At the same time, the rotation of the third lead screw 16 drives the driving wheel 18 to rotate. The rotation of the driving wheel 18 drives the driven wheel 17 to rotate via a synchronous belt. The rotation of the driven wheel 17 drives the fourth lead screw 20 to rotate. The rotation of the fourth lead screw 20 drives the first bevel gear 19 to rotate. The rotation of the first bevel gear 19 drives the second bevel gear 21 and the sixth bevel gear 30 to rotate. The above transmission method makes the second lead screw 15 and the sixth lead screw 25 rotate in the same direction, driving the first sliding frame 6 to slide; the fifth lead screw 24 and the seventh lead screw 25 rotate in the same direction. The lead screw 26 rotates in the same direction as the second lead screw 15 and the sixth lead screw 25, thereby driving the second sliding frame 31 to slide. Ultimately, this will cause the first sliding frame 6 and the second sliding frame 31 to slide towards each other on both sides of the lifting platform 9. At the same time, as the third lead screw 16 and the fourth lead screw 20 rotate, the lifting platform 9 is driven to rise. When the lifting platform 9 rises to its highest position, the first sliding frame 6 and the second sliding frame 31 are fully open and closed, the first servo motor 8 is turned off, and finally, electronic products are placed on the rotating plate 10 for display. When it is necessary to store the electronic products, the first servo motor 8 is restarted, causing the third lead screw 16 to rotate counterclockwise, causing the lifting platform 9 to descend to its lowest position. At this time, the first sliding frame 6 and the second sliding frame 31 slide relative to each other to close, storing the electronic products.

[0042] When the display angle of the rotating plate 10 needs to be adjusted, the operator starts the second servo motor 22. The second servo motor 22 drives the first lead screw 9011 to rotate. The rotation of the first lead screw 9011 causes the threaded block 9012 to slide. During the sliding of the threaded block 9012, the second connecting block 9015 will also slide. The sliding of the second connecting block 9015 will cause the first connecting rod 9013 to rotate appropriately. The rotation of the first connecting rod 9013 will cause the first connecting block 9014 to rotate, thereby adjusting the display angle of the rotating plate 10. The rotating plate 10 rotates around the damping axis, thereby changing the angle between the rotating plate 10 and the lifting platform 9. The rotation of the rotating plate 10 drives the third connecting block 9017 to rotate synchronously. The rotation of the third connecting block 9017 causes the second connecting rod 9018 to rotate. The rotation of the second connecting rod 9018 causes the fourth connecting block 9019 to slide. The sliding of the fourth connecting block 9019 causes the sliding block 9016 to slide in the second slide groove 902. When the angle between the rotating plate 10 and the horizontal plane is adjusted to the preset angle, the second servo motor 22 is turned off.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
