[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] The present application embodiment discloses a mobile advertising device. Figure 1 and Figure 2A promotional device that is easy to move includes two rectangular fixed columns 1, and a plate-shaped connecting rod 2 is fixedly connected to the side surfaces of the two fixed columns 1, and rollers 3 are fixedly connected to the lower surfaces of the two fixed columns 1, so that the device can be moved to any place, and frame-shaped installation frames 7 are snap-connected to the outer surfaces of the two fixed columns 1, and plate-shaped reinforcement plates 8 are fixedly connected to the two side surfaces of the two installation frames 7, so that after the device is moved to a designated location, the installation frame 7 is snap-connected to the outer surface of the fixed column 1 at a certain height, so that the reinforcement plate 8 is pressed against the ground, thereby increasing the stability of the device and enhancing the display effect;

[0021] Secondly, a rectangular parallelepiped sliding column 4 is slidably connected to the upper surfaces of the two fixed columns 1, and the two fixed columns 1 are slidably connected to a plate-shaped first promotional frame 5 through the two sliding columns 4, and a screw rod 9 is rotatably connected to the upper surface of the connecting rod 2, and the lower end of the screw rod 9 penetrates the connecting rod 2 to its lower surface, and is fixedly connected to a disc-shaped rotating disk 11, and the outer surface of the screw rod 9 is screwed and connected to a sleeve rod 10 through a ball screw, and the sleeve rod 10 is fixedly connected to the lower surface of the first promotional frame 5, so that the staff can rotate the rotating disk 11 to drive the screw 9 to rotate, so that the ball screw Under the action of the lead screw, the sleeve rod 10 is driven to slide up and down together with the first publicity frame 5, thereby changing the height of the device, which can not only make the device adapt to the height requirements of various occasions, but also can lower the height of the device during mobile transportation. At the same time, a plate-shaped second publicity frame 6 is rotatably connected to the upper surface of the first publicity frame 5, and the promotional content is posted through the first publicity frame 5 and the second publicity frame 6. Before moving and transporting, the second publicity frame 6 can be rotated downward to engage with the first publicity frame 5, thereby reducing the height of the device, making the device more convenient and quick during carrying and moving.

[0022] Reference Figure 3 A first arc-shaped groove 12 and a second arc-shaped groove 13 are provided on the side surfaces of the two fixing columns 1, and a first columnar limiting groove 14 is provided on the inner side walls of the two mounting frames 7. A first block-shaped limiting block 15 is elastically slidably connected to the inner wall of the first limiting groove 14 through a spring, and the first limiting block 15 can be engaged with the inner wall of the first groove 12 or the second groove 13, so that the first limiting block 15 can be pressed to make the first limiting block 15 away from the inner wall of the first groove 12. At this time, the spring is in a contracted state, and then the mounting frame 7 and the reinforcement plate 8 are slid upward, and then the first limiting block 15 rebounds and engages with the inner wall of the second groove 13 under the resetting action of the spring, so as to prevent the reinforcement plate 8 from affecting the movement and transportation of the device, so that the device can be moved quickly.

[0023] Reference Figure 4Two rectangular cavity-shaped card slots 16 are provided on the side surface of the second promotional frame 6, and two L-shaped slot-shaped slide slots 17 are provided on the side surface of the first promotional frame 5. The inner walls of the two slide slots 17 are slidably connected with L-shaped block-shaped sliders 18, and the two sliders 18 can be engaged with the inner walls of the two card slots 16, and arc-shaped third grooves 19 are provided on the upper surfaces of the two sliders 18. The inner top surfaces of the two card slots 16 are provided with columnar second limiting grooves 20, and the inner walls of the second limiting grooves 20 are spring-loaded. A block-shaped second limit block 21 is elastically slidably connected, and the second limit block 21 can be engaged with the inner wall of the third groove 19, so that after the second promotional frame 6 is rotated downward to fit the side surface of the first promotional frame 5, it is engaged with the inner wall of the slot 16 by sliding the slider 18. At the same time, the second limit block 21 is engaged with the inner wall of the third groove 19 under the action of the spring, so as to realize the rapid positioning of the second promotional frame 6 and the first promotional frame 5 after folding, thereby realizing rapid folding and unfolding, which is convenient for carrying and storage of the device.
