Abstract

The invention discloses a portable video demonstration stand for teaching, which comprises a base provided with a backlight board, where an LCD video monitor and a console are arranged on the base, the console is provided with a built-in rechargeable power source, and the LCD video monitor is connected with the console; a table lamp neck which is capable of torsional bending is fixed on the console, the table lamp neck is provided with a machine head in a fixed manner through a bracket, and the end part of the machine head is provided with a CCD lens; and both sides of the console are each provided with a light supplementary lamp provided with a table lamp neck. The portable video demonstration stand for teaching adopts the table lamp necks, achieves the telescopic purpose by replacing the complicated mechanical structure with the table lamp necks, and is simpler in structure when compared with other similar products; and the portable video demonstration stand is provided with the built-in rechargeable power source, thus the portable video demonstration stand does not need to be connected with a long wire in teaching, thereby greatly facilitating the usage in teaching.

Description

technical field [0001] The invention belongs to the technical field of teaching equipment, in particular to a video display stand. Background technique [0002] Common scanners currently on the market are generally CCDChargeCoupledDevice and photoelectric coupled sensor scanners according to the different photoelectric conversion elements. It focuses on the CCD through the lens, converts the light signal into an electrical signal image, and the latter is close to the surface of the scanned manuscript for contact scanning. The CCD scanner focuses on the CCD through the lens and directly senses the light, which can be very convenient for physical scanning. The photosensitive device CCD in the scanner is a relatively mature technology. Its cost is relatively low, but the imaging quality is getting higher and higher. The CCD using silicon single crystal technology has lower requirements on the ambient temperature and has a wider range of adaptation. With the development of te...
