Core of the present utility model is to provide a kind of glasses of adjustable eyeglass focal length, can focus, so as to reach people
To the reading requirements of various display images.
In order that those skilled in the art more fully understands technical scheme provided by the utility model, below in conjunction with attached
The utility model is described in further detail with specific embodiment for figure.
It refer to Fig. 1, a kind of glasses of adjustable eyeglass focal length provided by the utility model, including the first mirror holder 1 and consolidate
Horizontal glass piece 2, in addition to mobile eyeglass 4 and the retractor device for adjusting distance between fixing len 2 and mobile eyeglass 4, stretch
The first mirror holder of device connection 1 and mobile eyeglass 4.
The glasses that this programme provides, on the basis of the first mirror holder and fixing len including prior art, in addition to move
Index glass piece and retractor device, mobile eyeglass is arranged on the first mirror holder by retractor device, adjusts fixing len and moving lens
The distance between piece, so as to focus, function of the people to the reading requirement of various display images can be adapted to.
Preferably, the retractor device of this programme specifically includes the second mirror holder 403 and adjustment gear 5.Second mirror holder 403 connects
Move eyeglass 4 and be provided with rack.The size of rack matches with the gear teeth of adjustment gear 5.Adjustment gear 5 coordinates with rack to be passed
It is dynamic, for moving eyeglass 4 to closer or far from fixing len 2.Adjustment gear 5 is relatively turnable to be arranged on the first mirror holder 1.
That is, adjustment gear 5 and the cooperation of rack, cooperation is rolled equivalent to gear on rack.Certainly, retractor device can also be other
Device with Telescopic, e.g., chute or railroad, mobile eyeglass can be driven to slide, can also be consolidated in a certain position
Fixed, the distance relative to fixing len 2 is adjustable.Therefore, by the rotating band carry-over bar displacement of adjustment gear 5, so as to adjust
Mobile eyeglass and the distance of the first mirror holder or fixing len, so as to realize the regulation of focusing.Specifically, rack is hollow tooth
Bar, hollow rack can be opened in the centre of the second mirror holder 403.
Preferably, retractor device also includes the fixed plate 401 and bearing pin 402 being arranged on the first mirror holder 1, bearing pin 402
One end is connected on plate 401 and other end connection adjustment gear 5.Adjustment gear 5, which rotates, can drive bearing pin 402 in fixed plate
Rotated on 401 relative to it.
