Abstract

Focusable glasses are characterized by comprising zooming lenses (1) and adjusting control glasses legs (2), wherein each zooming lens (1) includes a front hard lens (3), a rear soft lens film (4) and a liquor cavity (5) formed between the front hard lens (3) and the rear soft lens film (4), and each adjusting control glasses leg (2) includes a liquor storage pipe (6), a rear bent rod (7), an adjusting pipe (8) and push-pull rods (9). The front ends of the liquor storage pipes (6) are fixed onto a glasses frame; the rear bent rods (7) are hung on ears; the adjusting pipes (8) are connected with the liquor storage tubes (6) and the rear bent rods (7); the push-pull rods (9) are arranged inside inner cavities of the liquor storage pipes (6) and the inner cavities of the adjusting pipes (8); and the liquor cavities (5) are communicated with the liquor storage tubes (6) by the aid of pipelines and filled with liquor (13). The focal points of the focusable glasses can be adjusted, and the focusable glasses effectively solve the problem of continuous visual deterioration, simultaneously omit the trouble of frequently buying new glasses, save time and money for people, and are a fine helper for people with poor eyesight.

Description

The adjustable focus glasses

Technical field

The utility model relates to glasses, is a kind of adjustable focus glasses specifically.

Background technology

Now a lot of people solve visual problems by wearing glasses, and the elderly corrects defects of vision with spectacles for long sight, and the young man corrects defects of vision with spectacles.Yet, owing to people do not note, such as frequently glasses being taken off or put on, will make that eyesight further goes down, and to this time in order to see thing clearly, again must not be less than one pair of new glasses of optician's shop deallocation, not only lose time, again can expensive money.So we need a kind of glasses of adjustable focus in the life.

Summary of the invention

The purpose of this utility model provides a kind of adjustable focus glasses.

Described adjustable focus glasses is characterized in that: these adjustable focus glasses comprise zoom eyeglass and regulation and control leg of spectacles; Described zoom eyeglass comprises preceding hard lenses and the back soft mirror film that tightly tails, and is provided with solution cavity between described preceding hard lenses and the soft mirror film in back; Described regulation and control leg of spectacles comprises that front end is fixed on liquid storage pipe on the mirror holder, terminal back knee, connects the adjustment pipe of liquid storage pipe and back knee and is located at the liquid storage pipe inner chamber and adjust the pull bar in the tube cavity; Described adjustment pipe is a hollow, cylindrical tube, inboard two of adjusting pipe respectively is provided with a toroidal cavity, middle inside is provided with internal thread, and the front end of the tail end of described liquid storage pipe and back knee is respectively equipped with the cylinder dop, and two cylinder dops are fastened in respectively in the groove of adjusting pipe two ends inwall; The front end of described pull bar is provided with piston and is embedded in the liquid storage pipe, and the afterbody of pull bar has external thread and the middle part interior with adjusting pipe is threaded; Described solution cavity is communicated with liquid storage pipe and is full of solution.

The focus of the utility model adjustable cheater effectively solves the problem that eyesight constantly goes down, and removes the trouble of frequently joining new glasses simultaneously from, for people save time and money, is dysphotia personage's good assistant.

Description of drawings

Fig. 1 is the utility model structural representation,

Fig. 2 is an A place partial enlarged drawing among Fig. 1,

Fig. 3 is a varifocal mirror chip architecture synoptic diagram.

Among the figure: 1-zoom eyeglass, 2-regulates and control leg of spectacles, hard lenses before the 3-, soft mirror film behind the 4-, the 5-solution cavity, the 6-liquid storage pipe, knee behind the 7-, 8-adjusts pipe, 9-pull bar, 10-cylinder dop, 11-groove, 12-piston, 13-solution.

Embodiment

Below in conjunction with accompanying drawing the utility model is further specified: adjustable focus glasses described in Fig. 1,2,3 is characterized in that: these adjustable focus glasses comprise zoom eyeglass 1 and regulation and control leg of spectacles 2; Described zoom eyeglass 1 comprises preceding hard lenses 3 and the back soft mirror film 4 that tightly tails, and is provided with solution cavity 5 between described preceding hard lenses 3 and the soft mirror film 4 in back; Described regulation and control leg of spectacles 2 comprises that front end is fixed on liquid storage pipe 6 on the mirror holder, terminal back knee 7, connects the adjustment pipe 8 of liquid storage pipe 6 and back knee 7 and is located at liquid storage pipe 6 inner chambers and adjust the pull bar 9 in pipe 8 inner chambers; Described adjustment pipe 8 is hollow, cylindrical tube, inboard two of adjusting pipe respectively is provided with a toroidal cavity 11, middle inside is provided with internal thread, the front end of the tail end of described liquid storage pipe 6 and back knee 7 is respectively equipped with 10, two cylinder dops 10 of cylinder dop and is fastened in respectively in the groove 11 of adjusting pipe 8 two ends inwalls; The front end of described pull bar 9 is provided with piston 12 and is embedded in the liquid storage pipe 6, and the afterbody of pull bar 9 has external thread and is threaded with middle part in adjusting pipe 8; Described solution cavity 5 is communicated with liquid storage pipe 6 and is full of solution 13.

Principle of the present utility model is summarized as follows: in the solution cavity 5 that forms between the soft mirror film 4 of hard lenses 3 and back before transparent solution 13 is filled in, integral body has just formed a zoom eyeglass 1 like this.Then, by increasing or reducing solution 13, will correspondingly make the middle part thickening or the attenuation of zoom eyeglass 1, thereby reach the purpose that changes zoom eyeglass 1 focus.The increase of solution 13 or minimizing then are to finish by the regulatory mechanism of regulation and control leg of spectacles 2.

With the concave lens is example, specifically implements as follows:

As shown in Figure 3, preceding hard lenses 3 is the meniscus sheet, and then soft mirror film 4 also presents concave shape.Be full of when solution 13 under the situation of some, center and the preceding hard lenses 3 of the soft mirror film 4 in back keeps certain distances, so whole zoom eyeglass 1 just has a focus, and this focus is suitable near-sighted personage's the initial eyesight number of degrees.

As time goes on, the eyesight of eyeglass wearer further goes down, and just needs this time to have adjusted the focus of zoom eyeglass 1.

We with hand clockwise or be rotated counterclockwise and adjust pipe 8, adjust pipe 8 with groove 11 around cylinder dop 10 from the axle rotation, adjust between pipe 8 and liquid storage pipe 6, the back knee 7 and be not subjected to displacement.

And in rotary course, because the afterbody of pull bar 9 is connected with adjustment pipe 8 inner threads, will force pull bar 9 to form an action that moves forward and backward like this, and the mobile effect that will form syringe type of pull bar 9, and drive piston 12 pushes away or takes out backward the solution 13 in the liquid storage pipe 6 forward, because liquid storage pipe 6 and solution cavity 5 are being communicated with by pipeline, like this solution 13 in the solution cavity 5 also can be corresponding the generation situation that increases or reduce, the relative distance of soft mirror film 4 in corresponding back and preceding hard lenses 3 will become big or diminish, thereby finally changed the focus of zoom eyeglass 1, adapted to the needs that the eyesight number of degrees change to reach.

The utility model also can be made into the long sight Zoom glasses.
