[0002] Multimedia projection is mainly composed of a projection lamp and a screen for projection. The projection lamp is facing the screen to display the image on the computer or mobile phone on the screen. Its main function is to enlarge the image so that it can be viewed more intuitively and clearly.

[0003] When using a projector in daily life, if you want to project clearly on the screen, a key issue is to align the projection lamp on the projector with the screen. Because, usually when installing, the projector and the screen are prefabricated in a fixed alignment position.

[0004] However, for many projectors used in homes or companies, the screen can be fixed on a wall or other location, but the projector has no suitable location to be fixed. Therefore, when using it in these scenarios, users are often required to debug and align it by themselves, which is more troublesome to use. Utility Model Content

The projector is located in the opening of the bracket, and the shaft is connected with the bearing; at the same time, a positioning mechanism is also provided on the bracket for fixing the shaft after it rotates.

[0007] Furthermore, the positioning mechanism includes two discs respectively located on both sides of the bracket, and the middle of the inner side of the disc is fixedly connected to the locking column one; at the same time, the outer end of the shaft is provided with a locking hole one that is compatible with the locking column one; in addition, the inner side of the disc is fixedly connected to a plurality of locking columns two distributed in a circular array, and the outer side of the bracket is provided with a plurality of locking holes two that are compatible with the locking columns two.

[0008] Furthermore, the first clamping column and the second clamping column are elastic columns, and their diameters are slightly larger than the corresponding clamping holes.

[0009] Furthermore, the ends of the first engaging column and the second engaging column are both constructed to form a rounded structure.

[0010] Furthermore, a convex block is fixedly connected to the outer side of the disc, and the convex block is used as a force-leveraging structure.

[0011] Furthermore, the inner wall of the connecting hole is fixedly connected to the outer ring of the bearing, and the inner ring of the bearing is interference fit with the shaft rod.

[0012] Technical effect: In the utility model, the projector is rotatably connected to the bracket through the action of the shaft rod, so that the projector can be rotated up and down in situ to adjust the position of the projection lamp to facilitate alignment with the screen, and after adjusting the position of the projection lamp, it can be fixed there through the action of the positioning mechanism, so that the position of the projection lamp can be flexibly adjusted, which facilitates the use of the projector.
