Description
【Technical field】
The utility model is related to teaching aid technical field, particularly, is related to a kind of myopia prevention glasses frame.
【Background technology】
Cause myopia in addition to heredity, topmost is exactly environmental factor, nearly state is regarded just because eyes are in for a long time
Caused myopia.Because eyes need not be adjusted when seeing the object of distant place, and when seeing object nearby, it is necessary to pass through ciliary
The contraction of flesh, making the convexity of crystal increases, and object nearby is fallen on the retina, what can just be seen is clear.When long
Between closely operation, such as read, write, seeing TV, Play Station games, eyes is adjusted anxiety for a long time, head is leaned forward,
Constantly fill white in eyeball, intraocular pressure increases accordingly, and extraocular muscle anxiety and oppression eyeball, or because regulation when draw
Vasa vorticosa, hampers the circulation of blood, weakens the resistance of sclera, causes axis oculi to extend and forms myopia.And it is existing
The instrument of many prevention and treatment myopia, such as treated using wears glasses (such as Micropole glasses etc.), be one of method.
But, existing glasses chip architecture can only be gone tender just ametropia after myopia has occurred for people with it, or be used for
Control myopia continues to develop, and does not have pre- myopic-preventing effect.And the students in middle and primary schools of growth and development stage are in, due to read-write posture
Incorrect, schoolwork burden is overweight in addition, and the ratio for suffering from myopia is but growing on and on, and various circles of society were once appealed again and again, makes every effort to change
This situation, but achieve little, people expect that a kind of createing as early as possible for the pre- myopic-preventing glasses of energy is come.
Therefore, it is necessary to provide a kind of new myopia prevention glasses frame.
【Utility model content】
The purpose of this utility model is to provide a kind of myopia prevention glasses frame.
The technical solution of the utility model is as follows：The myopia prevention glasses frame stretches including the first telescopic column, second
Column, the first fixed part and the second fixed part that are respectively arranged on first telescopic column and the second telescopic column bottom,
It is respectively arranged on first telescopic column and the connecting rope of the second telescopic column top first and the second connecting rope and connection institute
The set head circle of the first connecting rope and second connecting rope is stated, the set head circle includes the stretch cord of annular and located at the bullet
The Nearsighted prevention spectacles of power rope, the Nearsighted prevention spectacles include mirror holder and are bolted in the object lens and eyepiece at the mirror holder two ends, the object lens
For convex lens；The eyepiece is convex lens, and the focal length of the eyepiece is more than the focal length of the object lens, and the surface of the eyepiece is sticked
Partial veil, the object lens and eyepiece carry out high density by laser and got ready, the edge to the object lens and eyepiece will be carved in focal length.
It is preferred that, first telescopic column and first fixed part are hinged by the first rotating shaft, and described second
Telescopic column and second fixed part are hinged by second rotating shaft.
It is preferred that, in addition to located at the mirror holder and for adjusting the object lens and the focus control of eyepiece focal length.
It is preferred that, first telescopic column and second telescopic column are respectively provided with hydraulically extensible adjustment structure.
It is preferred that, first fixed part and second fixed part are clip.
The beneficial effects of the utility model are：The utility model is simple in construction, by the way that pre- myopic-preventing support is corrected
It is herein in connection with the order of the larger object lens of reverse telescope mid-focal length and the less eyepiece of focal length, focal length is smaller while sitting posture
Convex lens be placed on before, be used as object lens；The larger convex lens of focal length are put behind, as eyepiece, will thus amplify originally,
The effect for becoming near, which becomes, puts remote, diminution, therefore can effectively pre- myopia prevention, protect eyes；And this glasses adjustable distance, make
Word becomes remote, and relieving eye strain can long periods of wear.
【Brief description of the drawings】
Fig. 1 is the structural representation of the utility model myopia prevention glasses frame.
【Embodiment】
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Referring to Fig. 1, the myopia prevention glasses frame 100 includes the first telescopic column 1, the second telescopic column 2, set respectively
The first fixed part 3 and the second fixed part 4 in first telescopic column 1 and the bottom of the second telescopic column 2, it is respectively arranged on
First telescopic column 1 and top the first connecting rope 5 of second telescopic column 2 and the second connecting rope 6 and connect described the
The set head circle 7 of one connecting rope 5 and second connecting rope 6.
The set head circle 7 includes the stretch cord 71 and the Nearsighted prevention spectacles 72 located at the stretch cord 71 of annular, described anti-
Near-sighted glasses 72 are, with bimirror barrel structure, to specifically include mirror holder 721, be bolted in the object lens 722 and eyepiece at the two ends of mirror holder 721
723 and located at the mirror holder 721 and for adjusting the focus control 724 of the object lens 722 and the focal length of eyepiece 723, the object lens
722 be convex lens；The eyepiece 723 is convex lens, and the focal length of the eyepiece 723 is more than the focal length of the object lens 722, the mesh
The surface of mirror 722 is sticked partial veil.
The object lens 722 and eyepiece 723 carry out high density by laser and got ready, will be carved in focal length to the He of object lens 722
The edge of eyepiece 723, the structure can intuitively read the focal length of the object lens 722 and eyepiece 723.
In use, the stretch cord 71 of annular is first sheathed on head by user, then by the Nearsighted prevention spectacles 72 wear to
Eye, it is described that the object lens 722 and the focal length of eyepiece 723, also replaceable different focal can be adjusted by the focus control 724
Object lens 722 and eyepiece 723 further adjust, partial veil be used for antiultraviolet, further protection glasses.

The user of high and build, sets different height, it is ensured that the correct sitting posture and glasses of user facilitates all kinds of to the distance of desktop
The use of crowd.
Specifically, first fixed part 3 and second fixed part 4 are clip, clip can be clipped in desk
Edge, the fixed myopia prevention glasses frame 100.
The beneficial effects of the utility model are：The utility model is simple in construction, by the way that pre- myopic-preventing support is combined
The order of the larger object lens of reverse telescope mid-focal length and the less eyepiece of focal length, the less convex lens of focal length are placed on before,
It is used as object lens；The larger convex lens of focal length are put behind, and as eyepiece, thus will originally be amplified, and are become near effect and become
Remote, diminution is put, therefore can effectively pre- myopia prevention, protect eyes；And this glasses adjustable distance, word is become remote, alleviate eyes
Fatigue, can long periods of wear.
Above-described is only embodiment of the present utility model, it should be noted here that for the ordinary skill of this area
For personnel, on the premise of the utility model creation design is not departed from, improvement can also be made, but these belong to this practicality
New protection domain.
