Description

Micro projector screen dual purpose support frame

The utility model relates to a support frame, in particular to a micro projector cloth which is convenient to carry and store, is stable, easy to use, and is not easy to be damaged, and can be used together with a curtain of a micro projector and a camera, a camera and a micro projector. Curtain dual purpose support frame.

In recent years, due to the popularity of projectors and the maturity of small projector technology that can be carried around, the demand for business newsletters and other markets has become larger and larger, and the portable projection screen that can be carried with them is followed. The urgent need for the device.

However, the conventional portable projection screen device can be referred to the following Patent Document 1, which is a portable projection screen improved structure, which comprises a first support frame, a second support frame, a projection screen, and a link set. The first support frame is provided with a reel. The two sides of the projection screen are respectively connected to the second support frame and the reel, and the projection screen is wound around the reel. The connecting rod group is composed of two connecting rods which are pivotally connected to each other, two The left end of the connecting rod is fixedly pivotally connected to the left end of the first and second supporting frames, and the right ends of the two connecting rods are respectively slidably pivoted to the right half of the first and second supporting frames, respectively, by the connecting rod The group can support the second support frame and propel the projection screen when unfolding, and can also close the second support frame and retract the projection screen. In addition, the second support frame is further provided with a positioning seat and a sliding seat that can be fastened to each other, and the upper ends of the two links are respectively assembled to the positioning seat and the sliding seat to expand the connecting rod group and expand. In the end, the sliding seat can be driven by the upper end of one of the links and snapped to the positioning seat to achieve the function of positioning the unfolded state of the link group that is deployed to the bottom.

Patent Document 1: Domestic Patent Publication No. M402443 "Improved Structure of Portable Projection Screen", the announcement date is April 21, 2011.
