Description
Technical Field
The utility model relates to the technical field of projector curtains, in particular to a projector curtain adjusting device.
Background
Projection screens are one of the most commonly used products in projector peripherals. If the projection curtain is matched with the projector properly, a high-quality projection effect can be obtained. Projection screens can be functionally divided into two types, reflective and transmissive; reflection type is used for forward projection, and transmission type is used for rear projection; the front projection screen is divided into a plane screen and an arc screen; can be classified into glass curtain, metal curtain, embossed plastic curtain, etc. in terms of texture. In general, the picture effect of the hard curtain is superior to that of the soft curtain, the current projector curtain is directly fixed on the wall surface by the winding box, and at the moment, the angle of the curtain is limited by the fixing of the winding box, so that the left and right inclination angles of the curtain can not be adjusted according to different requirements, and the flexibility of the whole curtain is reduced.
For the problems in the related art, no effective solution has been proposed at present.
Disclosure of Invention
Aiming at the problems in the related art, the utility model provides a projector curtain adjusting device to overcome the technical problems existing in the prior related art.
For this purpose, the utility model adopts the following specific technical scheme:
the utility model provides a projecting apparatus curtain adjusting device, includes the fixed plate to and the projecting apparatus curtain mechanism that sets up on the fixed plate, the mounting hole has been seted up in the fixed plate four corners, fixed plate center department is provided with the U type seat, be provided with the arc through the bearing in the U type seat and change the piece, U type seat top is provided with step motor, projecting apparatus curtain mechanism includes rolling box, curtain, counter weight pole.
As a further scheme of the utility model, the output end of the stepping motor is fixedly connected with the top of the arc-shaped rotating block, and the rotation of the stepping motor drives the arc-shaped rotating block to rotate.
As a further scheme of the utility model, the rear end of the arc-shaped rotating block is fixedly connected with the rear side wall of the winding box, and the winding box is driven to rotate circumferentially by rotating the arc-shaped rotating block as the center of a circle.
The utility model has the beneficial effects that the fixing plate is fixed on the wall surface through the mounting holes at the four corners of the fixing plate by using the bolts, when the angle of the curtain is required to be adjusted, the stepping motor is directly driven to rotate forwards or reversely, the winding box is driven by the arc-shaped rotating block to rotate circumferentially by taking the arc-shaped rotating block as the center of a circle, and then the left-right inclination angle of the curtain is adjusted.
