Description

Technical Field

[0001] The present invention relates to the technical field of advertisement delivery, and in particular to an intelligent advertisement delivery system. Background Art

[0002] With the development of science and technology, the application of advertising is becoming more and more widespread. Nowadays, most places with large traffic such as shopping malls, office buildings, residential areas, catering places, schools, leisure places, etc. are equipped with display screens for advertising.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention provides an intelligent advertising delivery system. When the display screen needs to be changed from a horizontal screen to a vertical screen, the display screen is pulled forward, and the arc groove moves away from the sleeve, the limit bar moves away from the limit groove, and then the display screen is rotated. After that, the pulling force on the display screen forward is slowly released. The display screen moves backward under the action of the spring, and the frame drives the arc groove to move to be wrapped outside the sleeve, and the connecting column drives the limit bar to move to the inner cavity of the limit groove, thereby completing the angle adjustment of the display screen, thereby facilitating the display of horizontal screen advertisements or vertical screen advertisements, and greatly improving the delivery effect of advertisements;

[0019] 2. The intelligent advertising delivery system of the present invention wraps the sleeve with an arc groove to fix the display screen to prevent the display screen from rotating, and fixes the connecting column with a limit bar and a limit groove to prevent the connecting column and the display screen from rotating, thereby doubly fixing the display screen and improving the stability of the display screen, thereby ensuring the normal delivery of advertisements;

[0020] 3. In the intelligent advertising delivery system of the present invention, when the display screen is installed, the arc groove wraps the sleeve, and because the length of the column is the same as the length of the sleeve, the arc groove limits the column to prevent the sleeve from being separated from the column, thereby preventing the display screen from being pushed upward by children or other people due to misoperation, thereby preventing the sleeve from being separated from the column, thereby preventing the display screen from being separated from the installation position, and then avoiding the economic loss caused by the display screen falling and being damaged, thereby ensuring the normal delivery of advertisements;

[0021] 4. The present invention provides an intelligent advertising delivery system, wherein a cooling fan is used to dissipate heat from a display screen, and a cooling hole is used for ventilation and heat dissipation inside a frame. When replacing or repairing the cooling fan, the screws are unscrewed by a tool, and the frame is disassembled, thereby exposing the cooling fan, and then the cooling fan is replaced or repaired, which is convenient for maintenance of the delivery device, thereby ensuring normal operation of the advertising delivery work;

[0022] 5. The present invention provides an intelligent advertising delivery system. When the angle of the display screen is changed, the display screen drives the baffle to rotate. The baffle rotates on the surface of the brush. The heat dissipation holes on the baffle can be used for ventilation and heat dissipation inside the frame. A large amount of dust will adhere to the outside of the heat dissipation holes. When the baffle rotates with the display screen, the baffle rotates on the surface of the brush, and the brush cleans the attached dust, thereby ensuring the ventilation performance of the heat dissipation holes, thereby ensuring the heat dissipation performance of the display screen. That is, when the angle of the display screen is adjusted, the dust attached to the outside of the heat dissipation holes can also be cleaned, killing two birds with one stone.

[0023] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention, it can be implemented in accordance with the contents of the specification. In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the following specifically cites a preferred embodiment and describes it in detail with the accompanying drawings as follows.
