Multimedia speech table for providing green biochemical working environment

Abstract

The invention relates to a multimedia speech table for providing a green biochemical working environment, belonging to the field of office furniture. A prior multimedia speech table which is providedwith a CRT display and widely used in universities and other similar institutions has the design defect in the aspect of radiation protection, so that the invention aims at solving the problem. In thestructure of the speech table, a position between a kinescope and a keyboard below the table surface of the speech table is provided with an air isolation baffle; and the surface of the side of the air isolation baffle facing to the kinescope is provided with a metal lead plate in an adhibit way. With the utilization of the structure, the radiation protection of the sides and the back of the kinescope is effectively enhanced, and the related radiation biochemical harm is restrained. In addition, the air isolation baffle also contributes to guiding smelly hot gas from the CRT display toward the direction away from an operator. The multimedia speech table is beneficial to improving the working environment of a table user.

Description

technical field [0001] The invention relates to a multimedia lecture platform providing a green biochemical working environment, which belongs to the field of A47B office furniture. Background technique [0002] Existing a kind of multi-media lecture platform that has been widely used in colleges and universities and other similar institutions has installed CRT monitor has design defect, and this will start from the structure of CRT monitor installed therebetween, in CRT monitor structure, in order to restrain The radiation damage to the user caused by the X-rays produced by the electron beam bombarded by the electron gun in the picture tube is generally considered to be due to the use of a large thickness of lead-containing glass on the screen of the CRT display facing the user. In this way, the radiation dose of X-rays to the front of the user's head and upper body is weakened or suppressed, and at the side and rear of the CRT display picture tube, because this part is usu...

AI Technical Summary

Problems solved by technology

[0005] CRT monitors are cathode ray tube monitors. Due to their solid structure and low price, for a long period of time, podiums equipped with CRT monitors will also be used in crowded and active classrooms such as college classrooms, middle school classrooms, and elementary school classrooms. The place is still widely used, and the general health damage to relevant practitioners caused by the above-mentioned design defects in the radiation protection of the podium has not stopped.
