Abstract
The utility model discloses a television watching mirror. The television watching mirror comprises two mirror barrels and a frame connected with the two mirror barrels, wherein the mirror barrels comprise a group of convex lenses and concave lenses for enlarging an image visual angle, as well as a regulating construction member for controlling distances between the convex lenses and the concave lenses. The television watching mirror provided by the utility model is adopted, the television watching mirror can enlarge an imaging field angle of a television image on human eyes according to a certain multiplying power, people can see clear larger television images, and an imaging range of a background is reduced.
Description
Technical field
The utility model belongs to watches the mirror technical field, relates in particular to a kind of TV watching glasses capable of rectifying myopia.
Background technology
Televisor is a kind of electrical equipment that utilizes the visual pattern of electric method transmission activity immediately, and it utilizes the persistence of vision effect of human eye to manifest the rest image of a frame frame gradual change, forms visual live image.The life of dull dull house has been broken in the appearance of televisor, has increased many enjoyment to people, also is conducive to the various information of people's real-time contact, enlarges one's knowledge.But when seeing TV, it is too little that people often can run into the TV of watching, and human eyesight is not fine, and perhaps background interference is seen the problems such as TV.Existing solution is generally to adjust position (as closer from TV), perhaps weakens background to obtain better visual effect.
The utility model content
The utility model embodiment technical matters to be solved is, a kind of subtended angle and the TV watching glasses capable of rectifying myopia of controlling TV background range size that can be controlled at the television image of eyes imaging is provided.
In order to solve the problems of the technologies described above, the utility model embodiment provides a kind of TV watching glasses capable of rectifying myopia, comprise two lens barrels with described two frameworks that lens barrel is connected, described lens barrel comprises one group of convex lens and concavees lens of being used for the enlarged image visual angle, and the adjustment means that is used for controlling distance between described convex lens and concavees lens.
As the improvement of such scheme, described adjustment means is knob.
As the improvement of such scheme, described knob is connected with described concavees lens, to control described concavees lens in the position of lens barrel.
As the improvement of such scheme, described lens barrel is rotatable lens barrel, to regulate the length of described lens barrel.
As the improvement of such scheme, described lens barrel is comprised of body tube and adjusting lens barrel, and described body tube and adjusting lens barrel are threaded.
As the improvement of such scheme, the described mirror of watching also comprises the head hoop retainer plate.
Implement the utility model embodiment, have following beneficial effect:
The utility model provides a kind of TV watching glasses capable of rectifying myopia, applicable to any televisor, compared with prior art, the described lens barrel of mirror of watching comprises one group of convex lens and concave lens that are used for the enlarged image visual angle, and the adjustment means that is used for controlling distance between described convex lens and concavees lens.The combination of convex lens and concavees lens can make image aspects amplify, and it adopts regulates the subtended angle of television image in human eye and replaced mobile people to watch position or the mobile television position of TV.Realize that by knob distance is adjustable between convex lens and concavees lens, can obtain different enlargement factors.In addition, described lens barrel is rotatable lens barrel, can regulate the length of described lens barrel, thereby realizes that the background scope is adjustable, blocks unnecessary bias light, avoids the interference of bias light.
In a word, the utility model can amplify the subtended angle of television image imaging on human eye by certain multiplying power, people are seen more clear, larger television image, and background scope of imaging on human eye is reduced.
Description of drawings
Fig. 1 is the structural representation of the utility model TV watching glasses capable of rectifying myopia the first embodiment;
Fig. 2 is the cut-open view of watching the lens barrel of mirror shown in Figure 1;
Fig. 3 is the structural representation of the utility model TV watching glasses capable of rectifying myopia the second embodiment.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is described in further detail.
In conjunction with Fig. 1 and Fig. 2, the utility model embodiment provides a kind of the first embodiment of TV watching glasses capable of rectifying myopia, comprise two lens barrels 1 and the framework 2 that is connected with described two lens barrels 1, described lens barrel 1 comprises one group of convex lens 11 and concavees lens 12 of being used for the enlarged image visual angle, and the adjustment means 13 that is used for controlling distance between described convex lens 11 and concavees lens 12.The combination of described convex lens 11 and concavees lens 12 can make image aspects amplify, and it adopts regulates the subtended angle of television image in human eye and replaced mobile people to watch position or the mobile television position of TV.
Described adjustment means 13 is knob.Described knob 13 is connected with described concavees lens 12, controlling described concavees lens 12 in the position of lens barrel, thereby realizes that the distance between convex lens 11 and concavees lens 12 is adjustable, can obtain different enlargement factors.
If the focal length of selected convex lens 11 is 3cm, the focal length of concavees lens 12 is 1cm, regulates the distance of concavees lens 12 and convex lens 11, makes imaging between concavees lens 1cm and 2cm, just the picture that can become to stand upside down and amplify in the same side.The selected focal length of convex lens 11 is larger, and the selected focal length of concavees lens 12 is shorter, and enlargement factor is larger.
When seeing TV, people only require that generally amplifying 1 to 6 times of left and right can satisfy our requirement.So, select the focal length of convex lens 11 and concavees lens 12 to differ greatly.Adjusting knob 13, the picture that makes 11 one-tenth, convex lens is less times greater than one times of focal length places of concavees lens 12 time, and this moment, enlargement factor can be in the scope of our demand.
Described lens barrel 1 is rotatable lens barrel, to regulate the length of described lens barrel 1.As one of embodiment of rotatable lens barrel, described lens barrel 1 is by body tube 14 and regulate lens barrel 15 and form, described body tube 14 and regulate lens barrel 15 and be threaded.Regulate lens barrel 15 and body tube 14 by rotation, namely can regulate the length of described lens barrel 1, control the distance that lens barrel 1 front end leaves convex lens 11, leave distance longer, the scope of light that can enter convex lens 11 is less, can avoid the interference of the outer signals except useful signal (TV signal), thereby realize that the background scope is adjustable, block unnecessary bias light.
Need to prove, the utility model watches mirror to realize the adjustable mode of distance between convex lens 11 and concavees lens 12, perhaps regulates the mode of the length of described lens barrel 1, all can make adjustment according to actual needs.
Also need to prove, described framework 2 can adopt plastics, metal etc. to make, but is not limited to this.
Mirror the second embodiment that watches shown in Figure 3, from shown in Figure 1 watch mirror the first embodiment different be that the described mirror of watching also comprises head hoop retainer plate 3, increases to wear the comfort level of watching mirror.
In sum, the televisor course of work described in the utility model is, when seeing TV, puts on and watches mirror, and adjusting knob and optical tube length are until we obtain satisfied image.
Above disclosed is only the utility model preferred embodiment, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim still belongs to the scope that the utility model is contained.
