Abstract
The utility model relates to a shield for preventing electromagnetic radiation, comprising a working table, a mainframe box body, a computer box body, a keyboard bed plate bracket, etc., which is characterized in that the computer box body is arranged under the working table. The inner surfaces of the mainframe box body and the computer box body is coated with the functional coating for preventing electromagnetic radiation. An optical inversion system is assembled on the working table. The structure of the system is that the glass for preventing the leakage of the electromagnetic wave is assembled on the working table; the primary reflection eyeglass for preventing the leakage of the electromagnetic wave and reflecting the image on the screen is assembled under the working table. A secondary reflection eyeglass for reflecting the image on the screen is hinged with the upper part of the working table. The utility model has the advantages of shielding the computer and the relative equipment, breaking maximumly the electromagnetic wave generated by the computer and the relative equipment, and avoiding the radiation injury of the electromagnetic wave to the operator for the computer in a long time. The utility model can also prevent the external interference of electromagnetic wave and leakage ofinformation of the computer, making the computer run safely and reliably. At the same time the optimal apparent distance and the ocular angle are provided, and the optical fatigue is relieved.
Description
Technical field
The utility model belongs to a kind of electromagnetic wave radiation shielding device that prevents computer.
Background technology
Up to now, avoid irradiation of electromagnetic waves, before display, install additional often and be coated with ITO, MgF in order to make the staff who is engaged in computation for a long time
2The clear glass of composite membrane, its effect are to absorb electromagnetic wave, anti-reflection visible light, but this shielding is inadequate, because electromagnetic generation is not only at display, and main frame, printer, comprise that keyboard, mouse all are the irradiation of electromagnetic waves sources, therefore, as long as near computer, just be subjected to the injury of electromagenetic wave radiation in various degree inevitably, simultaneously, irradiation of electromagnetic waves causes the leakage of information of computer easily, or suffers the interference of external electromagnetic waves, influences the normal operation of computer.In addition, the optimum viewing distance of perusal display screen is its cornerwise 5-7 times, and in fact this distance is difficult to keep, and is to the personnel of long-term use computer, especially very big to teen-age eyesight influence.
The utility model content
The purpose of this utility model provides a kind of electromagnetic wave radiation shielding device that prevents, can shield computer and relevant device, can prevent the interference of external electromagnetic waves again, and best sighting distance can also be provided simultaneously.
The purpose of this utility model is achieved by the following technical solution: it comprises workbench, the main frame casing, computer casing and Keyboard supporting board etc., it is characterized in that: the computer casing be arranged on work top below, the functional coating of the inner surface coated anti-electromagnetic radiation of main frame casing and computer casing, on workbench, assemble optical inversion system, the structure of this system is to be assembled with anti electromagnetic wave to leak glass on work top, and assembling has the also primary event eyeglass of reflective viewing screen image of anti electromagnetic wave leakage under work top, at the secondary reflection eyeglass of work top upper articulation reflective viewing screen image.
The utility model has the advantages that: computer and relevant device are shielded, its electromagnetic wave that sends is accomplished to block to greatest extent, make the personnel that are engaged in computation for a long time avoid the electromagenetic wave radiation injury, can prevent the interference of external electromagnetic waves again and prevent the computerized information leakage, make computer security, operation reliably, best sighting distance and visual angle can also be provided simultaneously, alleviate the fatigue of vision.
Description of drawings
