Both sides of the lower fixing plate 104 have grooves that match the thickness of the display panel 101, which fix the placement of the two display panels 101.

[0024] The connecting support rod 106 is fixedly connected to the connecting base plate 105 and is located at both ends of the connecting base plate 105. The universal wheel 107 is connected to the connecting support rod 106 and is located at the bottom end of the connecting support rod 106. The fixed cylinder 108 is fixedly connected to the connecting base plate 105 and is located at the top center of the connecting base plate 105, and is fixedly connected to the connecting support rod 106. The lifting adjustment assembly is installed on the fixed cylinder 108 and is connected to the lower fixed plate 104. The connecting base plates 105 are a pair, respectively disposed below both ends of the lower fixed plate 104. A fixed cylinder 108 is fixedly installed at the top center of each of the two connecting base plates 105. A lifting adjustment assembly is provided at the upper end of each of the two fixed cylinders 108. The lifting adjustment assembly is connected to the bottom of the lower fixed plate 104, thus connecting the lower fixed plate 104 to the lifting and moving device. The distance between the lower fixed plate 104 and the fixed cylinder 108 is adjusted by the lifting adjustment assembly, thereby adjusting the lifting height of the display panel 101. Connecting support rods 106 are fixedly installed at both ends of the connecting base plates 105. One end of each connecting support rod 106 on the connecting base plate 105 is fixedly connected to the outer wall of the fixed cylinder 108. Each of the four advertising racks is equipped with casters 107 with brake components at its bottom. The rotation of the casters 107 drives the movement of the advertising rack, and when the advertising rack is fixed, its position can be fixed by the brake components of the casters 107. Therefore, when installing the advertising rack, first connect the lifting adjustment component to the lower fixed plate 104, then fix the fixed cylinder 108 on the lifting adjustment component, so that the four casters 107 stand on the ground. Then, the lower fixed plate 104 is placed horizontally by the lifting and moving device. Then, the upper bracket 102 is installed above the lower fixed plate 104 by the connecting rod 103. Finally, the two display boards 101 are placed in the groove of the lower fixed plate 104 and fixedly clipped onto the upper bracket 102, thereby completing the installation of the advertising rack.

[0025] Secondly, the connecting screw sleeve 109 is fixedly connected to the lower fixing plate 104 and is located at the bottom of the lower fixing plate 104; the upper end of the telescopic support rod 110 is threadedly connected to the connecting screw sleeve 109, and the lower end of the telescopic support rod 110 extends into the fixing cylinder 108 and is connected by the fixing member; the fixing member passes through the telescopic support rod 110 and the fixing cylinder 108. The telescopic groove 114 is provided in the fixing cylinder 108 and cooperates with the telescopic support rod 110; the two fixing holes 115 pass through the fixing cylinder 108 and are located at the upper end of the fixing cylinder 108. Two connecting threaded sleeves 109 are symmetrically fixedly installed on the bottom of the lower fixing plate 104. The inner side of each connecting threaded sleeve 109 is threaded, and the outer sides of the upper ends of the two telescopic support rods 110 are provided with matching threads. By screwing the upper end of each telescopic support rod 110 into the connecting threaded sleeve 109 for thread locking, a detachable connection between the telescopic support rod 110 and the lower fixing plate 104 is achieved. The lower end of each telescopic support rod 110 extends into the telescopic groove 114 of the fixing cylinder 108. The telescopic groove 114 provides conditions for the telescopic installation of the telescopic support rod 110, and the fixing cylinder 108... The upper end extends through and is provided with two fixing holes 115, which are opposite to each other and cooperate with the fixing member. The fixing member passes through the fixing holes 115 and through the telescopic support rod 110 to realize the fixed installation of the telescopic support rod 110 and the fixing cylinder 108. Therefore, by moving the telescopic support rod 110 up and down in the telescopic groove 114 of the fixing cylinder 108, the height position of the lower fixing plate 104 is adjusted. The position is fixed by the fixing member, so that the lifting adjustment assembly can lift and adjust the height position of the lower fixing plate 104 and the display plate 101.

[0026] Meanwhile, the insertion rod 111 passes through the fixed cylinder 108 and the telescopic support rod 110; the locking nut 112 is threadedly connected to the insertion rod 111 and is sleeved on the outside of the insertion rod 111. A plurality of adjustment holes 113 are evenly distributed on the telescopic support rod 110 and pass through the telescopic support rod 110. The number of insertion rods 111 and the number of fixing cylinders 108 are matched, and the diameter of the plurality of vertically spaced and evenly arranged adjustment holes 113 on the telescopic support rod 110 is matched. The plurality of adjustment holes 113 penetrate the telescopic support rod 110 laterally, and the size of the adjustment holes 113 is matched with the size of the fixing holes 115 on the fixing cylinder 108. By aligning the two ends of one adjustment hole 113 with the two fixing holes 115 on the fixing cylinder 108, the insertion rod 111 is inserted through the adjustment hole 113 and the fixing hole 115. The locking nut 112 is rotated and sleeved on the insertion rod 111 and abuts against the fixing cylinder 108. Thus, the telescopic support rod 110 and the fixing cylinder 108 are fixedly connected by the fixing component.

[0027] When using the advertising rack of this utility model, first connect the lifting and adjusting assembly to the lower fixed plate 104, then fix the fixed cylinder 108 on the lifting and adjusting assembly, so that the four casters 107 stand on the ground. Then, the lower fixed plate 104 is placed horizontally by the lifting and moving device. Then, the upper bracket 102 is installed above the lower fixed plate 104 by the connecting rod 103. Finally, the two display boards 101 are placed in the groove of the lower fixed plate 104 and fixedly clipped onto the upper bracket 102, thus completing the installation of the advertising rack. The height of the display board 101 can be adjusted by the lifting and moving device, making it more convenient to view the advertisement and expanding the application scenarios of the advertising rack.
