Problems solved by technology
The connection between the display shielding cavity of the electromagnetic shielding table and the main machine shielding box and the printer shielding box is directly connected through the through-hole. Too many line connections will generate electromagnetic interference and affect the work of the display.
In addition, for the sealed display shielding chamber, main machine shielding box, and printer shielding box, the specific conditions inside the sealed box cannot be observed due to the darkness of the sealed box, which may cause damage to the substrate during installation and disassembly, and may also cause damage to the working process. It is impossible to observe the working condition of the body in time, which leads to the burning of the body, etc.

The invention relates to a modified electromagnetic shielding desk comprising a top plate, a keyboard plate, a mainframe shielding case, a printer shielding case and a monitor shielding chamber. The monitor shielding chamber disposed between the mainframe shielding case and the printer shielding case is fixedly connected to the top plate. Each of the monitor shielding chamber, the printer shielding case and the mainframe shielding case is provided with a shielding door. Partitions among the monitor shielding chamber, the mainframe shielding case and the printer shielding case are provided with through holes. A shielding tube for connecting the through holes is added into the monitor shielding chamber. The shielding tube is provided with a through hole communicated with the monitor shielding chamber. Therefore, the monitor shielding chamber, the mainframe shielding case and the printer shielding case are communicated. The shielding tube helps greatly decrease the electromagnetic interference of a mainframe body; a shielding window and lamps allow the mainframe body to be more convenient to assemble and disassemble and allows running state of the mainframe body to be observed in time.
Description
technical field [0001] The invention relates to the technical field of office equipment, in particular to an improved electromagnetic shielding table. Background technique [0002] Now the use of computers has penetrated into all aspects of people's lives such as institutions, schools, and families, and the harm of electromagnetic radiation to the human body has attracted people's attention. The connection between the display shielding cavity of the electromagnetic shielding table and the main machine shielding box and the printer shielding box is directly connected through the through-hole. Too many line connections will generate electromagnetic interference and affect the work of the display. In addition, for the sealed display shielding chamber, main machine shielding box, and printer shielding box, the specific conditions inside the sealed box cannot be observed due to the darkness of the sealed box, which may cause damage to the substrate during installation and disasse...
