[0005] Advantageously, each of the sliding frames is provided with auxiliary frames fixedly connected to the upright posts on both sides, the auxiliary frames are provided with sliding grooves, the sliding grooves are slidably connected with sliding posts, and two vertically symmetrical connecting rods are fixedly connected between the sliding posts and the advertising board, thereby ensuring the stability of the advertising board when sliding up and down and its normal wind resistance;

[0006] Advantageously, the advertising board is fixedly connected with an advertising poster, and the advertising poster is fixed to the surface of the advertising board by pasting, so that the staff can tear it off for replacement;

[0007] Advantageously, three fixing plates are fixedly connected to the upper end surface of the fixing base, each of the fixing plates is fixedly connected to a controller, and the three controllers respectively control the three motors.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] The utility model provides a sliding column, a connecting rod and an auxiliary frame. The sliding column slides in the auxiliary frame, and the sliding column is fixedly connected to the advertisement board by the connecting rod, so as to ensure the stability of the advertisement board when it moves up and down, and ensure the normal wind resistance of the advertisement board. The motor corresponding to each advertisement frame is controlled by the corresponding controller, which can facilitate the staff to replace the advertisement content of one of the advertisement frames separately later, thereby ensuring the safety when replacing the poster and the high replacement efficiency.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model. Example

[0019] See also Figure 1-7The utility model provides a technical solution: an advertising stand for quickly replacing advertising posters, comprising a fixed base 100, the upper end surface of the fixed base 100 is fixedly connected to a column 101, the side of the column 101 is fixedly connected to three power racks 104 distributed in a circumferential array, each of the power racks 104 is provided with a power cavity 114, and the power rack 104 is provided with two through holes 105 that penetrate the power cavity 114, the power rack 104 is slidably connected to a sliding rack 116 up and down, and the sliding rack 116 is partially located in the power cavity 11 4 clamps the power frame 104 to ensure stability during sliding, the side of the sliding frame 116 is fixedly connected to a motor 112, the other end of the motor 112 is connected to a rotating shaft 117 rotatably connected to the other side of the sliding frame 116, the rotating shaft 117 is fixedly connected to a gear 118 located in the power cavity 114, the sliding frame 116 is fixedly connected to a rack 115 located in the power cavity 114, the rack 115 is meshed with the gear 118, and the sliding frame 116 is fixedly connected to an advertising board 108.

[0020] Each of the sliding frames 116 is provided with auxiliary frames 106 fixedly connected to the upright posts 101 on both sides, and a sliding groove 107 is provided in the auxiliary frame 106, and a sliding column 119 is slidably connected in the sliding groove 107, and two vertically symmetrical connecting rods 111 are fixedly connected between the sliding column 119 and the advertising board 108, so as to ensure the stability of the advertising board 108 when sliding up and down and the normal wind resistance;

[0021] The advertising board 108 is fixedly connected with an advertising poster 109, and the advertising poster 109 is fixed to the surface of the advertising board 108 by pasting, so that the staff can tear it off for replacement;

[0022] The upper end surface of the fixed base 100 is fixedly connected to three fixed plates 102 , each of the fixed plates 102 is fixedly connected to a controller 103 , and the three controllers 103 are closed and respectively control the three motors 112 .

[0023] Working principle:

[0024] The fixed base 100 is fixed on the ground beside the highway. When the advertising poster 109 on one of the three advertising boards 108 needs to be replaced, the corresponding motor 112 is controlled by the bottom controller 103 to start, driving the rotating shaft 117 to rotate, the rotating shaft 117 drives the gear 118 to rotate, the gear 118 rotates and drives the sliding frame 116 to move downward along the rack 115, thereby driving the advertising board 108 to move down to the ground, and the staff will tear off the original advertising poster 109 and paste a new advertising poster 109;

[0025] Then the controller 103 controls the motor 112 to start again, and the motor 112 drives the sliding frame 116 to move up to the highest point and then stops, so as to display the advertisement.
