Abstract
The utility model provides a reading amplifier that does not distort the edge of the amplified image. An amplifying lens, which is a strip-shaped transparent semicylinder with vertical transects as both ends, is hinged with a U-shaped supporting frame. When the reading amplifier is used, the plane of the semicylinder of the lens of the reading amplifier is placed on a reading material in order to amplify words or figures. Because the lens of the reading amplifier applies the strip-shaped semicylinder structure with the vertical transects as both ends, the transverse amplified area is increased, the amplification distortion of the edge image of the lens is eliminated, and moreover, the reading amplifier is adapted to the reading habits of people and eases reading fatigue.
Description
Technical field:
The utility model discloses the distortionless reading glass in a kind of enlarged image edge, is to the improvement of existing magnifying glass, belongs to the optical amplification device technical field.
Background technology:
Existing reading glass is the convex lens disc-shaped structure, and serious deformation takes place the literal or the figure that amplify of its edge in use, has not only influenced to see and read effect, also can cause the user to feel dizzy for a long time, uses very inconvenient.
Summary of the invention:
The utility model provides a kind of enlarged image edge distortionless reading glass, has overcome the shortcoming of disc structure magnifier edge amplification effect distortion.
Technical solution of the present utility model is as follows: be hinged with amplifying lens on U type support, it is characterized in that: lens are transparent strip semicylinder, and two ends are vertical cross section.
Semicylinder plane with the utility model lens during use is placed on the literal or the figure that can obtain amplifying on the reading material.
Good effect of the present utility model is: lens adopt bar shaped semicylindrical lens structure, two ends are vertical cross section, have increased horizontal amplification area, and the magnification distortion of having eliminated the rims of the lens image now looks like, and the reading habit that is suitable for people has alleviated the reading fatigability.
Description of drawings:
Fig. 1 is the utility model structure principle chart.
Embodiment:
In conjunction with shown in Figure 1, lens 1 usefulness glass of the present utility model or plastics are made, and are transparent strip semicylinder, and two ends are vertical cross section, hinged U type support 2 on the transversal section, and the afterbody of support 2 is provided with handle 3;
Also lens of the present utility model can be embedded on the guide groove of reading frame, move up and down to read and use.
