Description

An adjustable focal length glasses

technical field

The utility model relates to the technical field of glasses, in particular to glasses with adjustable focal length.

Background technique

There are two main groups of people who need to wear glasses: one is myopic people, myopia is also called short-sightedness, because this kind of eye can only see near and not far. It is mainly due to the fact that parallel rays of light are focused in front of the retina after passing through the refractive system of the eye, which is called myopia. The other type is hyperopia, also known as presbyopia. It is mainly a refractive state in which the parallel light beam is refracted by the adjusted and relaxed eyeball and then imaged behind the retina. When the refractive power of the eyeball is insufficient or its axial length is insufficient, hyperopia occurs. Both nearsightedness and farsightedness can be corrected by wearing lenses. However, the degree of the eyes of these two groups of people will change, so that the glasses need to be replaced constantly, which causes inconvenience.

To this end, we introduce a kind of adjustable focal length glasses to solve the above problems.

Utility model content

The purpose of the present invention is to provide glasses with adjustable focal length to solve the above-mentioned problems in the background art.

In order to achieve the above purpose, the present invention provides the following technical solutions: a kind of spectacles with adjustable focal length, including a spectacle frame, a temple and a lens, the front end of the spectacle frame is symmetrically provided with two fixed frames for fixing the lenses, and The lower end of the fixed frame is provided with a fixed clip, both ends of the fixed clip are hinged with the spectacle frame through hinges, the lens is provided with a cavity inside, and the cavity is filled with liquid, and the lens is located between the fixed frame and the spectacle frame. Between the fixing clips, one side of the spectacle frame is provided with a fixing portion for fixing the temples, and the inner side of the fixing portion is provided with a fixing bolt, the fixing bolt is screwed with the fixing portion through a threaded groove, and one end of the fixing bolt passes through the fixing portion. The pin is connected with the fixed clip.

In this setting, a movable fixing strip is arranged at the bottom of the spectacle frame, and the two sides of the lens are fixedly connected with the spectacle frame and the fixing strip respectively, and then cooperate with the fixing bolts on the side of the spectacle frame. When it is suitable for you, you can push or pull the fixed clip through the fixing bolt, so that the lens will be twisted under the drive of the fixed clip, and the curvature of the lens will change after the twist, thus achieving the purpose of adjusting the focal length. .

Preferably, the lens is a sheet body made of flexible resin.

Preferably, the spectacle frame and the temple are fixedly connected by a rotating shaft.

Preferably, the end of the fixing bolt away from the lens is provided with a cross-shaped notch.

Preferably, the upper end of the fixing clip is provided with a pin hole.

Preferably, one side of the lens is fixedly connected to the fixing frame through screws and clamping grooves, and the other side of the lens is fixedly connected to the fixing strip through screws.

Compared with the prior art, the beneficial effects of the present utility model are as follows: the present utility model sets a movable fixing clip at the bottom of the spectacle frame, and the two sides of the lens are respectively fixedly connected with the spectacle frame and the fixing strip, and then With the fixing bolts on the side of the spectacle frame, when the degree of the glasses is no longer suitable for you, you can push or pull the fixing clips through the fixing bolts, so that the lens will be twisted under the driving of the fixing clips, and the lens will be twisted after twisting. The curvature will change, thus achieving the purpose of adjusting the focal length. Compared with the traditional spectacles, the utility model adopts a flexible resin lens, the purpose of adjusting the focal length is achieved by changing the curvature of the lens, and the structure is simple and the adjustment is more convenient.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to FIGS. 1-4 , the present invention provides a kind of spectacles with adjustable focal length, including a spectacle frame 1 , a temple 2 , and a lens 3 . The fixed frame 4 is fixed, and the lower end of the fixed frame 4 is provided with a fixed clip 5. Both ends of the fixed clip 5 are hinged with the spectacle frame 1 through hinges. The lens 3 is provided with a cavity 10 inside, and the cavity 10 Filled with liquid, the lens 3 is located between the fixing frame 4 and the fixing clip 5, one side of the spectacle frame 1 is provided with a fixing portion 6 for fixing the temple 2, and the inner side of the fixing portion 6 is provided with a fixing bolt 7 The fixing bolt 7 is screwed with the fixing part 6 through the threaded groove 8, and one end of the fixing bolt 7 is pinned with the fixing clip 5 through a pin shaft.

Specifically, the lens 3 is a sheet body made of flexible resin.

Specifically, the spectacle frame 1 and the temple 2 are fixedly connected by a rotating shaft.

Specifically, the end of the fixing bolt 7 away from the lens 3 is provided with a cross-shaped notch.
