The utility model discloses a set up a fixing clip strip that can move about bottom the spectacle frame, and two sides of lens respectively with spectacle frame and fixing strip fixed connection, the fixing bolt of deuterogamy spectacle frame side, when the degree number of glasses is no longer fit for oneself, accessible fixing bolt promotes or stimulates the fixing clip strip, the lens will twist reverse under the drive of fixing clip strip like this, the curvature of taking place to twist reverse the back lens will change, just so reached focus's purpose.
Description
Technical Field
The utility model relates to a glasses technical field specifically is an adjustable focus's glasses.
Background
There are two main categories of people who need to wear glasses: one is the group of myopic eyes, also called short-sighted eyes, because the eyes can only see near but not far. The main reason is that parallel rays are focused before the retina after passing through the eye dioptric system, which is called myopia. The other type is presbyopia, which is mainly a refractive state that parallel light beams are refracted by an adjusting and relaxing eyeball and then imaged behind a retina, and hyperopia is generated when the refractive power of the eyeball is insufficient or the length of the axis of the eyeball is insufficient. People with myopia or hypermetropia can be corrected by wearing the lens. However, the degree of eyes of the two groups of people can change, so that the glasses need to be changed continuously, and inconvenience is caused.
To this end, we propose an adjustable focal length glasses to solve the above problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an adjustable focus's glasses to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a glasses of adjustable focus, includes spectacle frame, glasses leg and lens, the front end symmetry of spectacle frame is equipped with two fixed frames that are used for fixed lens, and fixed frame lower extreme is equipped with the fixing clip strip, the both ends of fixing clip strip are all articulated through articulated elements and spectacle frame, the inside cavity that is equipped with of lens, and the cavity intussuseption is filled with liquid, the lens is located between fixed frame and the fixing clip strip, spectacle frame one side is equipped with the fixed part that is used for fixed glasses leg, and the fixed part inboard is equipped with fixing bolt, fixing bolt passes through thread groove and fixed part spiro union, and fixing bolt's one end is through round pin axle and fixing clip strip pin joint.
This setting is through setting up a fixing clip strip that can move about in spectacle frame bottom, and two sides of lens respectively with spectacle frame and fixing strip fixed connection, the fixing bolt of deuterogamy spectacle frame side, when the degree number of glasses is no longer fit for oneself, accessible fixing bolt promotes or stimulates the fixing clip strip, the lens will take place to twist reverse under the drive of fixing clip strip like this, the curvature of taking place to twist back lens will change, just so reached the purpose of adjusting the focus.
Preferably, the lens is a sheet made of flexible resin.
Preferably, the spectacle frame is fixedly connected with the spectacle legs through rotating shafts.
Preferably, one end of the fixing bolt, which is far away from the lens, is provided with a cross-shaped notch.
Preferably, the upper end of the fixing clamping strip is provided with a pin hole.
Preferably, one side of the lens is fixedly connected with the fixing frame through a screw and a clamping groove, and the other side of the lens is fixedly connected with the fixing clamping strip through a screw.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a set up a fixing clip strip that can move about bottom the spectacle frame, and two sides of lens respectively with spectacle frame and fixing strip fixed connection, the fixing bolt of deuterogamy spectacle frame side, when the degree number of glasses is no longer fit for oneself, accessible fixing bolt promotes or stimulates the fixing clip strip, the lens will twist reverse under the drive of fixing clip strip like this, the curvature of taking place to twist reverse the back lens will change, just so reached focus's purpose. Compared with the traditional glasses, the utility model discloses a flexible resin lens, through the purpose that changes the curvature of lens in order to reach focus regulation, its simple structure, regulation are more convenient.

Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the fixing portion of the present invention;
FIG. 3 is a schematic structural view of the fixing clip strip of the present invention;
fig. 4 is a schematic view of the lens structure of the present invention.
In the figure: the glasses comprise a glasses frame 1, glasses legs 2, glasses 3, a fixing frame 4, a fixing clamping strip 5, a fixing part 6, a fixing bolt 7, a thread groove 8, a pin hole 9 and a cavity 10.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Please refer to fig. 1-4, the utility model provides a glasses of adjustable focus, including spectacle frame 1, glasses leg 2, lens 3, the front end symmetry of spectacle frame 1 is equipped with two fixed frames 4 that are used for fixed lens 3, and fixed frame 4 lower extreme is equipped with fixing clip strip 5, the both ends of fixing clip strip 5 are all articulated with spectacle frame 1 through the articulated elements, lens 3 inside is equipped with cavity 10, and the intussuseption of cavity 10 is filled with liquid, lens 3 is located between fixed frame 4 and the fixing clip strip 5, spectacle frame 1 one side is equipped with fixed part 6 that is used for fixed glasses leg 2, and fixed part 6 inboard is equipped with fixing bolt 7, fixing bolt 7 passes through thread groove 8 and fixed part 6 spiro union, and the one end of fixing bolt 7 is through round pin axle and fixing clip strip 5 pin joint.
Specifically, the lens 3 is a sheet made of flexible resin.
Specifically, the spectacle frame 1 and the spectacle legs 2 are fixedly connected through rotating shafts.
Specifically, one end of the fixing bolt 7, which is far away from the lens 3, is provided with a cross-shaped notch.
