The electric telescopic rod 9 used is a commercially available component driven by a motor.

[0038] During use, when the transport reaches the display area, the plate 3 is driven to rise by the unfolding motor 14, and the first rotating plate 4 and the second rotating plate 5 are pulled out, so that the display area is unfolded outward, the display area is increased, and the promotional information is displayed.

[0039] In a preferred embodiment: the controller 6 is electrically connected to the driving motor of the electric telescopic rod 9, a storage groove is opened on the inner wall of the square box 8, and the inner wall of the storage groove is adapted to the outer wall of the electric telescopic rod 9, so that the electric telescopic rod 9 can be completely accommodated in the square box 8.

[0040] In the above structure, the electric telescopic rod 9 is controlled by operating the controller 6 to extend out of the square box 8. The top of the electric telescopic rod 9 is held by hand, and the extension height and descent of the electric telescopic rod 9 are accurately controlled by operating the controller 6 according to the needs of the user, so as to facilitate dragging and moving.

[0041] In a preferred embodiment: the controller 6 is electrically connected to the input end of the unfolding motor 14, and the screw drive assembly is symmetrically arranged with the plate 3 as the center to respectively drive the first rotating plate 4 and the second rotating plate 5.

[0042] In the above structure, by operating the controller 6, the unfolding motor 14 is used to drive the screw rod 2 to rotate, and the screw rod 2 drives the plate 3 to move up and down through the slider 10, so that the device can be folded when not in use, reducing the floor space.

After the two expansion plates 7 are rotated around the intersection axis respectively, they extend outward to expand the contact area between the equipment and the ground, so that the promotional equipment maintains a stable position and avoids instability of the equipment and causing overturning.

[0050] When the display is finished and the display needs to be stored, the expansion plate 7 is rotated by external force so that the extended end of the expansion plate 7 is stored at the bottom of the storage box 1. After the first rotating plate 4 and the second rotating plate 5 are recovered in the plate 3 along the upper slide groove of the plate 3, the control controller 6 drives the screw rod 2 to rotate through the unfolding motor 14, and the screw rod 2 drives the plate 3 to move up and down through the slider 10. Stored in the storage box 1.

[0051] When the device is not used, the baffle 13 is pulled, and the baffle 13 drives the circular plate 11 to move upward and compress the spring 12, so that the baffle 13 extends out of the top of the storage box 1, and the baffle 13 is conveniently rotated according to the protection and deployment needs, and the baffle 13 is used to protect the device.

[0052] When the display area needs to be recovered, after the plate 3 stores the first rotating plate 4 and the second rotating plate 5, it is lowered as a whole and recovered in the storage box 1, and the rear rotating baffle 13 is pulled to block the top opening of the storage box 1; when the plate 3 needs to be raised, the rear rotating baffle 13 is pulled to make the baffle 13 leave the top open area of ​​the storage box 1.

[0053] By operating the controller 6 and holding the top of the electric telescopic rod 9, the electric telescopic rod 9 is raised and lowered according to the user's use height, so that the device is easy to drag and move when used.

[0054] In a specific embodiment, it includes: hinged columns 21, rollers 22, meshing tooth surfaces 23; expansion plates 7 are arranged in pairs in the groove at the bottom of the storage box 1, and the meshing tooth surfaces 23 are arranged on the outer side wall of one end of the expansion plate 7; the expansion plate 7 is provided with a plug-in hole to be plugged with the hinged column 21; after the hinged column 21 is fully inserted into the expansion plate 7, the expansion plate 7 is stored in the storage box 1. The rollers 22 are symmetrically arranged in pairs on the opposite outer side walls at the bottom of the storage box 1.

[0055] When in use, the roller 22 is rolled, and a gap is left between the storage box 1 and the ground. After moving to the specified position, the expansion plate 7 is pulled down, and at the same time, one end of the expansion plate 7 arranged on one side of the storage box 1 is rotated. After the rotating end rotates out of the storage box 1, the meshing tooth surface 23 is engaged, which is beneficial to improve the connection reliability of the hinged end of the expansion plate 7.
