阅读说明：本技术 手机和平板电脑防辐射伤害的防护屏及其放大镜功能 (Protective screen for preventing radiation injury of mobile phone and tablet computer and magnifier function thereof ) 是由 李梓涵 于 2020-10-08 设计创作，主要内容包括：手机及平板电脑防辐射防护屏,在原结构、功能、操作方式的基础上,防护屏再增加一放大镜功能,可以远视距(安全距离50cm左右)观看机屏,进一步降低了辐射危害,并改善了视觉效果,可达到看电视的效果。(The radiation protection screen for the mobile phone and the tablet personal computer has the advantages that on the basis of the original structure, functions and operation mode, the protection screen is additionally provided with the function of the magnifier, so that the mobile phone and the tablet personal computer can be watched at a far distance (the safe distance is about 50 cm), the radiation hazard is further reduced, the visual effect is improved, and the effect of watching television can be achieved.)

1. The radiation-proof injury protective screen for the mobile phone and the tablet personal computer has the advantages that the original structure, the function and the operation mode are unchanged, and the radiation-proof injury protective screen is characterized in that the protective screen is additionally provided with a magnifier function, so that the image and text of the screen can be magnified, the screen can be watched at a far visual range, the radiation-proof effect is further achieved, and the visual effect is improved.

2. The magnifying glass function of claim 1, wherein the protective shield is configured to be raised and lowered while the protective shield is in its original configuration, thereby allowing for better selection of the manner and effect of operating and viewing the display.

The invention relates to a protective screen in a radiation injury preventing protective screen for mobile phones and tablet computers, which is additionally provided with a magnifying lens function and can magnify the pictures and texts of a screen.

The background technology 'mobile phone and panel computer protect against radiation damage protective screen', watch the mobile phone screen through the protective screen, the sight distance is near, namely near organism and radiation source, both influence the eyesight, still can have some influence of radiation. The picture and text are unclear when the viewer looks away from the visual range. If the protective screen has the function of a magnifier, the machine screen can be watched at a far sight distance (the safe distance is about 50 cm), and the effect of improving vision can be achieved.

The invention content is as follows: the invention aims to provide a radiation-proof protective screen for a mobile phone and a tablet personal computer, which has the function of a magnifier, can magnify pictures and texts of the screen while resisting radiation, achieves the purpose of watching the screen at a far distance, reduces radiation damage to the maximum extent, relieves eye fatigue and achieves the effect of watching television.

The purpose of the invention is realized as follows: the protective screen has the function of a magnifying glass simultaneously, and adds a corresponding structure: a protective screen can still normally operate according to the original operation mode; referring to fig. 1, a pair of lifting folding rods {2} is arranged above a protective screen at one fixed side of a back shell type bayonet {1} of an original machine body, if the protective screen {3} needs to be lifted, the protective screen {3} is lifted up manually, the protective screen {3} is lifted up, the lifting folding rods {2} are actuated, the protective screen {3} is lifted up automatically, and the protective screen {3} can be lifted up and fixed at any height of 0-10 cm. Fig. 2, back shell type bayonet {1}, lifting folding rod {2}, shield {3}, through the operation, the state that the shield rises.

The invention only needs to make the original protective screen into a magnifying glass type on the basis of the original structure, and a pair of lifting folding rods is arranged above the protective screen on one side where the protective screen is fixed.

Description of the drawings the detailed construction of the invention is given by the following examples and their drawings. Fig. 1 and 2 are front views of the protective screen and the magnifier function in the structure and the operation state.

The specific structural details and operation of the protective shield magnifying device according to the present invention will be described in detail with reference to fig. 1 and 2.

Detailed description of the inventionin fig. 1, the lifting folding rod {2}, which is 10cm long, is folded inward over the fixed side of the shield {1} in the non-use state, i.e., the lifting folding rod {2 }. When the protective screen is required to be lifted, the protective screen {3} is lifted slightly, namely the protrusion point at the inner side of the lifting folding rod {2} is actuated, the protective screen {3} can be lifted automatically and fixed at any height of 0-10 cm. Because the protective screen {3} and the lifting folding rod {2}, and the two sliding holes are internally provided with the telescopic antenna type clamping spring pieces, the fastening effect can be achieved.

The mobile phone protective screen simultaneously amplifies the functional structure and the operation mode, and can be replaced on the tablet personal computer.
