Description
Technical field
The present invention relates to eyewear arts, and in particular to a kind of dynamic varifocal glasses.
Background technique
Currently, conventional eyeglass lens power can not be adjusted, when eyeglass lens power is unable to satisfy user's need after a period of use
It asks, or when interim viewing somewhere is not known, traditional glasses cannot be focused, especially the big student of learning pressure or electricity
Brain worker, frequent with eye, eyes are easy fatigue and degree increase or increase of the elderly's hyperopia degree etc., intelligence are logical
Replacement glasses are crossed to realize, existing there is also some researchs adjusted about eyeglass lens power, such as the combination of multiple eyeglasses, weights
Folded setting or the adjustment of distance, however multiple lens combinations adjust degree and can not achieve dynamic, can only be the superpositions of degree, and
Distance is adjusted so that Glasses structure is complicated, it has not been convenient to be worn, in addition be realized also by the mode for being filled with liquid into glasses, so
And liquid is filled with or during being sucked out since the residual of drop will affect the clarity of glasses.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of dynamic varifocal glasses, and eyeglass is by hard lenses and tightly
The closely connected flexible lens composition for being attached to mirror surface before the hard lenses；Frame includes fixed frame, the first rotating bezel and the second rotation
Frame；The surrounding of the flexible lens is connected to first rotating bezel after the through-hole of the second rotating bezel by nylon wire drawing
On inside circumference wall；The front side of the nylon wire drawing and circumferencial direction between the first rotating bezel and the second rotating bezel is uniform
Being arranged multiple has damping clamping mechanism；First rotating bezel overcomes the resistance of damping clamping mechanism relative to the rotation of the second rotating bezel
So that nylon wire drawing stretches the flexible lens and then dynamic regulation focal length around after Buddhist nun's power.The present invention passes through hard lenses
The adjusting that can also realize dynamic focal length on the basis of original focal length with flexible lens, meets the variation of different eyes degrees.
It is of the invention to be specifically realized in：
Including frame, eyeglass, frame bracket, nose support and temple；The eyeglass is circle, by hard lenses and close patch
It is attached to the flexible lens composition of mirror surface before the hard lenses；The diameter of the flexible lens is less than the diameter of hard lenses；Institute
Stating frame is circular ring shape, including fixed frame, the first rotating bezel and the second rotating bezel；The hard lenses are embedded on fixed frame,
The surrounding of the flexible lens is connected to the interior of first rotating bezel after the through-hole of the second rotating bezel by nylon wire drawing
In the circumferential wall of side；The front side of the nylon wire drawing and circumferencial direction between the first rotating bezel and the second rotating bezel is uniformly set
Setting multiple has damping clamping mechanism；First rotating bezel overcomes the damping of damping clamping mechanism relative to the rotation of the second rotating bezel
So that nylon wire drawing stretches the flexible lens and then dynamic regulation focal length around after power, clamping mechanism is damped after adjusting
Damping force prevents first rotating bezel and the second rotating bezel from relatively rotating.
Hard lenses of the invention are configured basic degrees, cooperate degree the working as according to user of flexible lens
Preceding eyes degree configures, and flexible lens reset condition can meet the needs of near-sighted user is current, pass through rotating bezel
And nylon wire drawing is realized and stretches flexible lens, and then focuses, i.e. the adjusting of realization degree, and long sight user, configuration
Flexible lens are in stretching maximum rating when glasses, and adjusting flexible lens is opposite adjusting, that is, loosen flexible lens.
A kind of currently preferred embodiment, the nylon clamping mechanism include the clamping being arranged on the first rotating bezel

Diameter 2-3mm.
Specifically, the frame bracket 3 and temple 5 are both connected on fixed frame 1-2.
In order to realize that the clear and easy to adjust of glasses, the flexible lens 2-1 select the resilient gelatinous material of high transparency,
Its thickness is successively decreased from centre to periphery, peripheral edge thickness 1.5mm, and intermediate maximum gauge is 7mm, is stretched intermediate minimum thickness and is
3mm is, it can be achieved that 200 degree of eyeglass lens power is adjusted.As near-sighted user in use, the most basic setting with mirror is flexible lens 2-
1 unstretched state is equal to the degree with mirror person plus the degree of hard lenses 2-2 superposition, when needing to adjust degree, rotates mirror
Frame stretches flexible lens 2-1, and then increases myopia degree, as long sight user in use, the most basic setting with mirror is
Flexible lens 2-1 is equal to the degree with mirror person stretching degree of the maximum rating plus hard lenses 2-2 superposition, when needing to adjust
When degree, rotation frame loosens flexible lens 2-1, and then increases hyperopia degree.
In order to enable movement is smooth between two eyeglasses, while the clarity of glasses is not influenced, the flexible lens 2-1 and hard
The polyvinyl alcohol moisturizing lubricating fluid of 0.1mm is stained between matter eyeglass 2-2.
Specifically, the both ends of the nylon wire drawing 6 are bonded in flexible mirror after vulcanizing by silica gel 6-1 pressurized, heated respectively
On piece 2-1 and the first rotating bezel 1-1, silica gel pressurized, heated vulcanization after adhesion strength it is strong, can adhere to unlike material spectacle frame and
Eyeglass.
Specifically, the nylon wire drawing 6 is 6 surroundings being uniformly distributed with flexible lens 2-1, the damping clamping machine
Structure 7 is 25.
Specifically, the frame 1 is mixed using metal and plastics, and the plastic wraps metallic outer periphery, metal
Toughness and intensity are provided simultaneously with the frame that plastics are mixed.
The above, only the preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto, ability
Field technique personnel are not it should be understood that departing from the principle and spirit of the invention defined by the claims and their equivalents
In the case where, it can modify to these embodiments and perfect, these are modified and improve also should be in protection scope of the present invention
It is interior.
