Problems solved by technology

But there is following problem: when the field of view of the viewfinder is too small, that is, when the image projected on the large screen is too large, it is difficult for the teacher to accurately find the field of view of the viewfinder on the workbench of the teaching display stand. While looking at the large screen, adjust the position of the viewfinder and the position of the display object to achieve the purpose of placing the display object just in the field of view of the viewfinder, which wastes a lot of classroom time and reduces teaching efficiency

Abstract

The invention discloses a teaching display stand with a laser-assisted positioning function. The teaching display stand comprises a workbench, a side lamp, a supporting arm, a view finding device, a camera and the like. The teaching display stand is characterized in that: the teaching display stand further comprises a laser-assisted positioning device, the laser-assisted positioning device can emit a frame-shaped laser beam to frame out the visual field area of the view finding device, the laser-assisted positioning device and the camera are fixed to the lower end of the view finding together,and when the position of the view finding device is adjusted through the supporting arm, synchronous change can be guaranteed to the area framed by the frame-shaped laser beam emitted to the workbench by the laser-assisted positioning device and a visual field area of the view finding device. The structure has the beneficial effects that: the visual field area of the display stand is marked through the frame-shaped laser beam emitted by the laser-assisted positioning device, a user of the display stand for teaching is assisted in rapidly positioning the visual field area of the display stand,the time spent in adjusting a display object into the visual field area of the view finding device is saved, and the classroom efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of display stands, in particular to a display stand for teaching. Background technique [0002] At present, teaching display stands are widely used in classroom teaching in junior and senior high schools. Teachers place textbooks, documents, teaching materials and other display objects on the workbench of the display stand, and project the image on the large screen through the viewing device of the display stand. During use, the image projected on the large screen can be enlarged or reduced by adjusting the height of the viewfinder or adjusting the field of view of the viewfinder. But there is following problem: when the field of view of the viewfinder is too small, that is, when the image projected on the large screen is too large, it is difficult for the teacher to accurately find the field of view of the viewfinder on the workbench of the teaching display stand. Adjusting the position of the viewfinder a...
