Problems solved by technology

[0003] In the past, in school multimedia classrooms, projectors were installed. The projectors are generally installed on the top of the wall. A controllable telescopic rod is installed above the projector. The telescopic rod is fixedly connected to the wall. Install the curtain on the wall, the installation position of the curtain needs to be determined according to the position of the projector, but often due to the deviation of the installation, the image projected by the projector on the curtain will be biased to one side of the curtain, and the up and down directions can be adjusted by telescopic rod adjustment, but the left and right directions of the projector cannot be adjusted, resulting in uncoordinated left and right directions of the resulting image, or distorting the image, thus affecting the quality of teaching

Abstract

The invention relates to an adjusting device, and discloses an ejecting device for a projector. The ejecting device is arranged on a wall and comprises a telescopic rod. A sliding groove is formed in the wall. A sliding block is connected with the sliding groove in a sliding manner. The telescopic rod is fixedly connected to the sliding block. A supporting plate and a bottom plate located below the supporting plate are connected between the two side walls of the sliding groove in a sliding manner. The telescopic rod penetrates the supporting plate and the bottom plate and is in clearance fit with the supporting plate and the bottom plate. Ejector blocks penetrating the supporting plate are arranged on the supporting plate. A shear fork type lifter is arranged below the ejector blocks in an abutting manner and fixedly connected to the bottom plate. Compared with the prior art, images formed by the projector can be more coordinated through left and right movement of the sliding block.

Description

technical field [0001] The invention relates to a clamping device for a projector.
