In order to make the advertising content more vivid and interesting, a projection device for advertising is needed. The projection device is used to display the advertising content in a unique form. This online and offline combination of publicity makes a deeper impression on the audience. The existing advertising projection device is mainly composed of a projector, a bracket and a projection screen. The projector is supported by the bracket, and the projector is used to project the promotional advertisement onto the projection screen to explain the publicity to the audience.

[0003] Existing application number CN202122715911.0 The utility model discloses an advertising device for digital media with projection function, including a device body, a projection lens movably installed at the middle position of the device body, a projection cloth installed at the bottom side end of the device body, one end of the projection cloth is fixedly connected to the hanging rod, the projection cloth is rolled up on the outer surface of the shaft rod as a whole, the rear side end of the device body is connected to a fixing plate, both ends of the device body are installed with external loudspeakers, and one side of the heat-conducting aluminum sheet is installed with a cooling fan. The whole is facilitated by the shaft rod at the lower side end of the device body and the projection cloth that can be stored, and the projection lens that can be adjusted in angle and distance can be adjusted to facilitate the convenience of actual projection operation. In addition, by adding a lighting lamp controlled by a photosensitive sensor, the lighting effect inside the elevator can be provided in time when a fault occurs inside the elevator, thereby increasing the safety of the elevator to a certain extent when a fault occurs.

[0004] Based on the above, in order to increase the publicity effect, the existing advertising projection devices often need to carry out projection publicity in different occasions, so the position of the projection device needs to be moved frequently. The brackets are mostly tripod structures. Although the support is stable, it is inconvenient to flexibly fine-tune the projection device after the support, making it inconvenient to quickly and accurately align the projection device with the screen. In addition, most of the publicity venues are open-air squares or large shopping malls. The large flow of people makes it easy for the projection device to be accidentally hit by pedestrians and tip over. The projector is a precision instrument and is easily damaged after being hit, and the maintenance cost is high. Utility Model Content
