The setting of the limit groove can make the sliding plate slide more smoothly in the unfolding plate, and the setting of the locking screw can fix the sliding position of the sliding plate, thereby adjusting the height of the sliding plate and the curtain. the

Preferably, in order to facilitate maintenance of the projector, the bottom of the box is connected to the box body through threads. the

Preferably, in order to easily pick up the lid, a lifting rod is also provided on the lid. the

Preferably, in order to carry and move the device conveniently, a push-pull rod is provided on the outer surface of the box. the

Preferably, rollers are provided on the box bottom on one side corresponding to the push-pull rod, and supporting legs corresponding to the rollers are provided on the other side. the

Beneficial effects: the utility model has the following beneficial effects:

(1) The structure design of the utility model is ingenious, and the projection length is indirectly increased through the reflection of the mirror surface, and the hinged box body of the mirror surface can adjust its reflection angle, and the installation of the curtain unfolding device can adjust the distance between the projector and the curtain through the unfolding position of the unfolding plate The projected length and projected position, and the support plate and the extended support plate that can be drawn are set up to increase the force point and the extended length of the unfolded plate. The structure design is reasonable and has strong practicability;

(2) When the utility model is in use, a projector, a reflective mirror surface and a curtain unfolding device can be used to obtain a better quality playback and projection effect in a smaller space, and after use, the curtain unfolding device and the extended support plate are both It can be returned to the original position, the volume and occupied space of the whole device are greatly reduced, and it is easy to carry and move. the
