Description

Technical Field

[0001] The utility model relates to the technical field of projection live broadcast equipment, in particular to an interactive projection live broadcast equipment. Background Art

[0002] The positioning of the projection live broadcast equipment during installation depends on the desired effect and the type of screen, and the interactive projection equipment is equivalent to projecting two or more projection devices onto the same projection cloth at the same time, and then multiple projection devices interact with each other to obtain a more gorgeous image. However, in live broadcast use, two projection devices are generally used for interactive projection. After the projection device is installed, when the position is adjusted, the angle of the projection device will change. Therefore, during use, the position of the projection device needs to be reset. In the prior art, for the sake of convenience, the bracket used in the interactive projection device will fix the projection device, so that the projection device cannot be adjusted. Although it can be transferred more quickly, if the two projection devices are offset, the interactive image cannot be presented. Therefore, an interactive projection live broadcast device is needed to solve the above problem. Utility Model Content

In use, the two device bodies 18 can be driven to move and adjust by sliding the slide frame 4. At the same time, the slide frame 4 will drive the slide bar 5 to move during the movement. The movement of the slide bar 5 drives the fixed frame 7 to move. The movement of the fixed frame 7 drives the rotating wheel 8 to move. The slide bar 5 is given a downward elastic potential energy through the spring 6, which can make the slide bar 5 through the fixed frame 7 to make the rotating wheel 8 tightly contact with the inner ground of the slide groove 3, so that the slide frame 4 can have an instant stop effect during the movement of the outer surface of the fixed plate 2. When the movement of the slide frame 4 stops, the spring 6 limits the position between the rotating wheel 8 and the slide groove 3, so that the slide frame 4 stops moving, and then the device body 18 stops moving, so that it is more convenient and stable when adjusting the position of the device body 18.

[0021] The bottom of the rotating plate 9 is fixedly connected with a supporting plate 10, and both sides of the supporting plate 10 are provided with rotating grooves 11;
