Description

Technical Field

[0001] The utility model relates to the technical field of advertisement display devices, in particular to a mobile advertisement device. Background Art

[0002] Advertising refers to the activities of advertisers (including industrial and commercial enterprises, institutions, groups, individuals, etc.) using the strategies and means of advertising operators to publicize and disseminate advertising information to the public through certain media or forms. Existing advertising devices usually use brackets to support billboards, and passively promote through the information on the billboards. There are also ways to advertise through loop playback on electronic display screens, but existing advertising devices have the defect of being inconvenient to move.

[0003] Patent CN220340888U proposes a movable advertising device, which is threadedly connected to the base through a first screw. The first screw is rotated to drive the slider to move downward along the slide groove, and the bottom plate is driven to move downward, so that the bottom wall of the suction cup contacts the ground, thereby increasing the support area and improving the placement stability of the advertising display board; the second screw is rotated to drive the connecting plate to move upward. Since one end of the connecting plate is fixedly connected to the support column, it is convenient to adjust the height of the advertising display board. At the same time, the other end of the connecting plate pulls the piston to move upward, so that negative pressure is generated at the suction cup, which improves the fixing effect, and the negative pressure increases with the increase of the height of the advertising display board.

[0004] In the above scheme, the suction cup contacts the ground to ensure the stability of the device when it is stationary. At the same time, it also has a movable structure to facilitate changing the position of the advertising device. However, in this method, the highlight part of the display board is exposed. First, the display range is limited. In addition, the paper advertisements pasted on the display board are easily affected by the external environment and damaged or dropped when moving.

When the device is used, the display screen 21 is unfolded by the driving component 3, and the bottom column 37 passes through the base 1 and contacts the ground to support the device. When the device needs to be moved, the display screen 21 is folded and retracted by the driving component 3, and the moving wheel 11 contacts the ground. The device can be manually pushed to move through the push frame 12.

[0023] In this embodiment, a slide groove 23 is provided on the surface of the base 1 at the bottom of the three-group hinge shaft seat 22, and a slider is slidably connected in the slide groove 23. The bottom of the frame of the hinge shaft seat 22 is fixed to the slider in the slide groove 23. The driving assembly 3 also includes a linkage rod 35. Three groups of linkage rods 35 are equidistantly connected to the surface of the screw ring 32 through a rotating shaft, and the other end of the linkage rod 35 is rotatably connected to the hinge shaft seat 22 through a rotating shaft. When the screw 31 rotates the screw ring 32 and engages with the screw 31 for vertical movement, the linkage rod 35 pulls the hinge shaft seat 22 to slide along the slide groove 23, thereby contracting and expanding the display screen 21.

[0024] In this embodiment, a bottom plate 36 is fixed to the surface of the screw ring 32 that penetrates into the base 1, and four bottom columns 37 are fixed equidistantly at the bottom of the bottom plate 36. The bottom columns 37 can slide out of the base 1. A hole is provided on the top of the base 1 for the screw ring 32 to slide through.
