Background technology
Current era science and technology develop rapidly and people's daily life level improve day by day, and the technical renovation of electronic product is also experiencing earth-shaking change.Along with electronic product, comprise the appearance of iPad, MP4 and mobile phone, electronic product just comes into huge numbers of families in the mode of " screen enlarging ", " lightly changing ".
The visual enjoyment that electronic product brings is apparent for twenty-twenty beholder.But, for some myopia populations, have to when watching TV programme be with near-sighted glasses.In like manner, hyperope then needs to wear farsighted glasses (convex lens) and just can reach program viewing effect clearly.But, although wear myopia or farsighted glasses can enable the people of viewing MP4/ mobile phone see image more clearly, but long-time wearing spectacles can make people not feel well, and head must be comparatively proper during wearing spectacles, if head is arbitrarily leaned against on sofa or pillow, likely cause glasses to tilt, affect viewing effect.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide little, the portable light angle emitted by imaging source on adjustment electronic curtain of a kind of volume clearly can see the portable snap-in presbyopia of word on screen or pattern or near-sighted screen mirror to meet myope or hyperope clearly without the need to wearing spectacles.
For achieving the above object, a kind of portable cards of the utility model enters formula presbyopia or near-sighted screen mirror, it comprises for the dovetail clip of holding electronic product, top cover and coupling arrangement, it is characterized in that: described top cover comprises frame, the light refraction device suitable with electronic product screen, and described light refraction device is detachable to be installed in described frame; Described coupling arrangement comprises loose-leaf, the first expansion link, the second expansion link and universal joint, described loose-leaf is connected in series upper leaf plate by axle core and lower leaf plate forms, described lower leaf plate is connected with described dovetail clip, and one end of described first expansion link is welded on described upper leaf plate, the other end of described first expansion link is fixedly linked by described universal joint and the second described expansion link, and described top cover is installed on the second described expansion link.
On the basis of such scheme preferably, described light refraction device is convex lens.
On the basis of such scheme preferably, described light refraction device is concavees lens.
On the basis of such scheme preferably, described light refraction device is Fresnel lens.
On the basis of such scheme preferably, the end face of described top cover near electronic product screen side is provided with a cushion pad.
On the basis of such scheme preferably, the end face that described top cover deviates from electronic product screen side is provided with a transparent protective film.
On the basis of such scheme preferably, described light refraction device comprises by the prism group organized the prism that coordinates between two more and rearrange.
The utility model compared with prior art, its beneficial effect is: adopt portable snap-in presbyopia of the present utility model or near-sighted screen, according to user be near-sighted or long sight selects this light refraction device to be convex lens or concavees lens, light enters human eye after the refraction of light refraction device, and then image clearly can be formed on the retina, user is without the need to wearing near-sighted glasses or farsighted glasses clearly can watch screen; And coordinate top cover, dovetail clip and the coupling arrangement of installing light refraction device, top cover can be realized facilitate it to use with the overlapping of electronic curtain and carry, simultaneously, adopt between dovetail clip and top cover and adopt loose-leaf, the first expansion link, universal joint and the second expansion link, by the change of the first length of telescopic bar with the focal length of light regulating refracting means, improve light refraction device refraction effect further.

Embodiment
By describe in detail the utility model technology contents, structural attitude, reached object and effect, hereby exemplify embodiment below and coordinate accompanying drawing to be explained in detail.
Refer to shown in Fig. 1, and shown in composition graphs 2 to Fig. 4, the utility model provides a kind of portable snap-in presbyopia or near-sighted screen mirror, it comprises for the dovetail clip 10 of holding electronic product, top cover 20 and coupling arrangement 30, wherein, top cover 20 comprises frame 21, the light refraction device 22 suitable with electronic product screen, and light refraction device 22 is detachable to be installed in frame 21; Coupling arrangement 30 comprises loose-leaf 31, first expansion link 35, second expansion link 36 and universal joint 37, loose-leaf 31 is formed by axle core serial connection upper leaf plate and lower leaf plate, lower leaf plate and dovetail clip 10 are fixedly linked, and one end of the first expansion link 35 is welded on upper leaf plate, the other end of the first expansion link 35 is connected with the second expansion link 36 by universal joint 37, and top cover 20 is installed on the second expansion link 36.
During use, screen mirror of the present utility model is clamped on electronic product by dovetail clip 10, second expansion link 36 is turned to the second expansion link 36 and the first expansion link 35 plumbness around universal joint 37, now top cover 20 is in parallel shape with the screen of electronic product, and between top cover 20 and the screen of electronic product, there is certain distance, the light that electronic curtain produces, human eye is entered after light refraction device 22 reflects, form image clearly on the retina, thus make user just can know see screen clearly without the need to wearing spectacles or spectacles for long sight, in use procedure, user also can promote top cover does 360 ° rotary motion around the relative dovetail clip 10 of universal joint 37, thus to guarantee that user can know each image seen clearly on electronic curtain.
Preferably, according to user be near-sighted or long sight is selected, light refraction device 22 of the present utility model can be convex lens or concavees lens, light enters human eye after the refraction of light refraction device 22, and then image clearly can be formed on the retina, user is without the need to wearing near-sighted glasses or farsighted glasses clearly can see screen clearly; Simultaneously, in order to improve the refraction effect of light refraction device 22 further, user can regulate the height of the first expansion link 35 as required, thus the distance changed between human eye, light refraction device 22, electronic curtain, thus realize the object of its focusing, clearerly can see screen clearly to make user; When not using, user, by shrinking the first expansion link 35, folding second expansion link 36 and loose-leaf 31, makes top cover 20 and electronic curtain be parallel to each other, and makes top cover 20 and electronic curtain bonded to each other, thus reduces its volume, facilitates it to carry.Preferably, when being that electronic curtain is fitted to prevent top cover 20, wearing and tearing electronic curtain, cause the not fogging clear of formation, the end face of top cover 20 of the present utility model near electronic product screen side is provided with cushion pad, and is provided with a transparent protective film at the end face that this top cover 20 deviates from electronic product screen side.
As the preferred version of this case, light refraction device 22 of the present utility model is Fresnel lens, guarantees that it is lightly easy to carry to reduce its volume, and this light refraction device 22 comprises by the prism group organized the prism that coordinates between two more and rearrange.
In sum, be only the preferred embodiment of the utility model, do not limit protection domain of the present utility model with this, all equivalence changes done according to the utility model the scope of the claims and description with modify, be all within scope that the utility model patent contains.
