Abstract

The utility model discloses a remote radiation proof computer display device relating to a radiation proof computer device. The utility model comprises a first flat mirror 1, a second flat mirror 2, and a magnifier or a telescope 3, wherein, the first flat mirror 1 is equiped on left or right of a computer display screen 4; the second flat mirror 2 opposites to the first flat mirror 1; while the magnifier or telescope 3 opposites to the second flat mirror 2. Light of the computer display screen 4 incidences to the first flat mirror 1 to form a symmetrical virtual image, of which the light is reflected to the second flat mirror 2 to revert to a virtual image similar to that of the computer display screen 4, thus human eyes 5 can see an amplifying and clear image via the magnifier or the telescope 3. The utility model has simple structure, is convenient for producing and using; generally, electromagnetic radiation will be reduced along with a square value of the distance from a radiation source, by using the utility model, the display screen is inclined equiped before a person with a distance of 2-3m, thus has good defending effect, and adapts to varieties of computer users.

Description

A kind of remote radiation proof computer screen device

Technical field

The utility model relates to a kind of computer shielding, relates in particular to a kind of remote radiation proof computer screen device, specifically, relates to first level crossing, second level crossing, magnifying glass or telescopical combination.

Background technology

Today, the whole world enters the information age of digitlization, networking, and the application of computer is penetrated into all trades and professions.Along with the development and the The rise of electronic commerce of Internet technology, computer has entered people's work, study, various fields of recent life, and is all-pervasive, exist everywhere.Not only factory, enterprise, shop, office, school, hospital use computer in a large number, and computer has also entered huge numbers of families, become a kind of household electrical appliance.Especially service industries such as finance, post and telecommunications, security, insurance, traffic administration be unable to do without computer especially.Hundreds of millions people use computer, and the epoch of Long contact time computer arrive.Computer radiate influences health, has been users' problems very deeply concerned.Though the electromagnetic radiation that computer sends is not too strong, yet going up machine, some people reaches several hrs every day, throughout the year month after month from uninterruptedly.The cumulative dose of so accepting radiation is just many.To some responsive crowds such as women, children, especially nourish the pregnant woman of fetus especially, will produce what bigger influence and consequence.

Is how electromagnetic radiation protected to computer? keeping certain distance with radiation source is one of effective safeguard procedures, because electromagnetic radiation intensity is along with descending with the square value of the distance of radiation source.In addition, reducing the time that contacts with computer etc., also is important, is to be directly proportional with the product of exposure time with radiation intensity because accept the cumulative dose of radiation.Although the machine time is necessary in the minimizing, be difficult in practice accomplish.Expert advice computer user should keep 2～3 meters in computer display screen.Keep at a distance in computer both sides and rear portion and to be no less than 1.2 meters.

Summary of the invention

The purpose of this utility model just is to overcome the shortcoming and defect that prior art exists, and a kind of remote radiation proof computer screen device is provided.

The purpose of this utility model is achieved in that

As Fig. 1, the utility model is made up of first level crossing 1, second level crossing 2, magnifying glass or telescope 3; First level crossing 1 places the left side or the right of computer display screen 4, and second level crossing 2 is relative with first level crossing 1, and magnifying glass or telescope 3 are relative with second level crossing 2.

Its light path is the virtual image that light incident first level crossing 1 of computer display screen 4 gets a symmetry, the light of this virtual image reflexes to second level crossing 2 again, be reduced into the virtual image the same with computer display screen 4, through magnifying glass or telescope 3, make human eye 5 see a kind of amplification, clearly as.

Operation principle of the present utility model is as follows:

The usual computer that uses generally places the display screen forward before the human eye between 0.5～1 meter; Obviously, electromagnetic radiation injures greatly the people.And use the utility model to place before the human eye between 2～3M display screen is oblique; Obviously, can drop to minimum to people's injury electromagnetic radiation.

The utility model must be selected to install than the spacious room.

The utlity model has following advantage and good effect:

1, simple in structure, produce easily, easy to use.

2, because electromagnetic radiation intensity along with descending with the square value of the distance of radiation source; And use the utility model to place before the people between 2～3M display screen is oblique, so protection effect is good.

3, be applicable to men and women, old and young's computer user of service.

Description of drawings

Fig. 1-the utility model structural principle schematic diagram;

Fig. 1-the utility model structure embodiment schematic diagram.

Wherein:

1-the first level crossing; 2-the second level crossing;

3-magnifying glass or telescope; 4-computer display screen; 5-human eye;

6-support, 6.1-base, 6.2-pull bar, 6.3-ball and socket joint.

Embodiment

Describe in detail below in conjunction with drawings and Examples.

As Fig. 2, first level crossing 1, second level crossing 2, magnifying glass or telescope 3 are placed respectively on the support 6.

Support 6 is made up of base 6.1, pull bar 6.2, ball and socket joint 6.3; From top to bottom, base 6.1, pull bar 6.2, ball and socket joint 6.3 connect successively.

Pull bar 6.2 can make first level crossing 1, second level crossing 2, magnifying glass or telescope 3 liftings and rotation freely.

Ball and socket joint 6.3 can make first level crossing 1, second level crossing 2, magnifying glass or telescope 3 pitching freely.

So by regulating the position of base 6.1, the pitching of ball and socket joint 6.3 is regulated in adjusting yoke 6.2 length and rotation, can make fully human eye see a kind of and computer display screen 3 the same clearly as.
