[0030] The lower lifting frame 21, the middle lifting frame 22 and the upper lifting frame 23 are mutually sleeved and arranged to lift the flip plate 26. The electric push rod 24 provides the power source required for flipping the flip plate 26. The connecting rod 25 connects and fixes the electric push rod 24 and the flip plate 26. The flip plate 26 is connected to the display screen and transmits the flipping force.

[0031] A connecting frame 27 is threadedly provided at one end of the lower end of the flip plate 26, and the connecting frame 27 is threadedly fixed to one end of the connecting rod 25 through a movable shaft passing through one end. A hinge 28 is threadedly provided at the other side of the lower end of the flip plate 26, and one end of the hinge 28 is fixed to the other side of the upper end of the inner wall of the upper lifting frame 23.

[0032] The connecting frame 27 connects and installs the connecting rod 25 and the flip plate 26, and the hinge 28 allows the flip plate 26 to adjust the angle.

[0033] The drive unit also includes a drive motor 31, a ball screw 32 and a movable end 33; the drive motor 31 is threadedly connected to one side of the bottom end of the cavity 16, and the output end of the drive motor 31 is fixed with a ball screw 32, and the outer surface of the ball screw 32 is equidistantly provided with movable ends 33, and the movable ends 33 are respectively threadedly fixed to the lower lifting frame 21, the middle lifting frame 22, and the upper lifting frame 23;

[0034] The driving motor 31 provides a power source, and the ball screw 32 cooperates with the movable end 33 to transmit force and convert the curvilinear motion into linear motion. The movable end 33 can fix the structure of the lower lifting frame 21, the middle lifting frame 22 and the upper lifting frame 23 while transmitting force;

[0035] Working principle: When the display screen is lifted and flipped, a rotational force is applied to the ball screw 32 through a controlled driving motor 31, and the movable end 33 on the ball screw 32 is fixedly installed between the lower lifting frame 21, the middle lifting frame 22 and the upper lifting frame 23 respectively, so that force can be transmitted to synchronously adjust the height of the lower lifting frame 21, the middle lifting frame 22 and the upper lifting frame 23 to complete the height adjustment of the display screen. After the height adjustment is completed, a driving force is applied to the connecting rod 25 through a controlled electric push rod 24, so that the flip plate 26 can be flipped to flip the display screen in linkage;

[0036] This step can synchronize the lifting and lowering of the display screen when it is flipped, effectively saving time and improving work efficiency.

[0037] See also Figures 1-4 As shown, this embodiment is based on the above embodiment 1 and further includes a moving part, the moving part includes a base 11 and a cavity 16; a cavity 16 is opened on one side of the upper end of the base 11;

[0038] The cavity 16 satisfies the installation of the above-mentioned drive motor 31 structure and provides storage space;

[0039] The moving part further includes a band brake wheel 12, a threaded column 13, a bracket 14 and an auxiliary guide wheel 15; the band brake wheels 12 are symmetrically fixed at the lower corners of the base 11, and a threaded column 13 is threaded on one side of the lower corner of the base 11 close to the band brake wheel 12. The lower end of the threaded column 13 is fixed with a bracket 14, and an auxiliary guide wheel 15 is rotatably installed at the lower end of the bracket 14;

[0040] The rolling between the band brake wheel 12, the auxiliary guide wheel 15 and the contact surface can meet the movement of the mechanism. The threaded column 13 mounts the bracket 14 and can be adjusted in height by means of screw thread expansion and contraction. The auxiliary guide wheel 15 is installed and fixed by the bracket 14. While meeting the load-bearing movement, the auxiliary guide wheel 15 can meet the use in multiple environments by means of lifting adjustment;

[0042] The sealing plate seals the cavity 16;

[0043] The front end of the base 11 is equidistantly provided with heat dissipation holes 17, and movable handles 19 are threadedly connected to the upper parts on both sides of the base 11;

[0044] The heat dissipation holes 17 meet the internal heat dissipation of the cavity 16, and the movable handles 19 provide the power required for the movement of the base 11;

[0045] An inspection plate 18 is provided through the middle of the front and back of the base 11, and threaded holes extending into the base 11 are provided through the upper end of the inspection plate 18;

[0047] Working principle: During the movement of the mechanism, when the display screen is not installed, the rolling contact between the band brake wheel 12 and the contact surface can be independently used to complete the movement of the mechanism. After the display screen is installed, a rotational force can be applied to the threaded column 13 to adjust the auxiliary guide wheel 15 to a level angle with the band brake wheel 12, and they can contact the contact surface together to complete the movement. During the movement on uneven ground, the auxiliary guide wheel 15 can be adjusted to a higher position to prevent the lower end of the base 11 from contacting the contact surface and affecting the movement;

[0048] This step can improve the applicability and functionality of the structure and meet different usage requirements.
