Abstract
The utility model provides a hydraulic lens which comprises a plastic transparent bag, wherein the transparent bag is communicated with a sleeve through a conduit; a piston is arranged in the sleeve; and transparent liquid is filled in the transparent bag. In the hydraulic lens provided by the utility model, the focal length can be changed at will; and the mass of the hydraulic lens is over 50% lighter than glass. The hydraulic lens is simple to produce; and a great quantity of energy is consumed for producing the same glass lens, and the processes are complicated. Through the hydraulic lens provided by the utility model, the focus degree of the glasses of people can be changed anytime without often replacing the lenses with different degrees; and the hydraulic lens is simple to use.
Description
Technical field
The utility model relates to the optical mirror slip technical field, particularly a kind of hydraulic pressure lens.
Background technology
The lens that prior art provides all are that glass sheet forms, only if its focal length polishing, otherwise can not change, inconvenience used, and process is complicated.
The utility model content
The utility model provides a kind of hydraulic pressure lens that can change focal length arbitrarily.
To achieve these goals, the utility model provides following technical scheme:
A kind of hydraulic pressure lens, it comprises: plastic transparent bag, said transparent bag is communicated with sleeve through conduit, is equiped with piston in the said sleeve, is equiped with transparency liquid in the said transparent bag.
Through implementing above technical scheme, have following technique effect: the hydraulic pressure lens that the utility model provides, can change focal length arbitrarily, the quality of these hydraulic pressure lens is lighter more than 50 percent than glass.Make simply, and make same glass mirror process need consumption mass energy, process is complicated.Be used for the people and wear glasses and to change the focus number of degrees at any time, do not take the eyeglass that often changes the different number of degrees.And usage is simple.
Description of drawings
The structural representation of the hydraulic pressure lens that Fig. 1 provides for the utility model embodiment;
The user mode figure of the hydraulic pressure lens that Fig. 2 provides for the utility model embodiment.
Embodiment
In order better to understand the technical scheme of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
The utility model embodiment provides a kind of hydraulic pressure lens; As depicted in figs. 1 and 2; It comprises: plastic transparent bag 101, and said transparent bag 101 is communicated with sleeve 104 through conduit, is equiped with piston 103 in the said sleeve 104; Be equiped with transparency liquid 102 in the said transparent bag 101, this transparency liquid 102 is water or water glass etc.When using piston and sleeve when the pressurization of above-mentioned space advances, just as the principle of having an injection, the space pressurization of liquid this moment in transparent bag.Behind the transparent bag pressurized to the position dilatational strain of establishing in advance.
The light transmission is on the expander that above-mentioned transparent bag forms, and can change refractive direction this moment, caused the focus change.
Above-mentioned hydraulic pressure lens can change focal length arbitrarily, are applicable to concave-convex lens.Above-mentioned hydraulic pressure lens are applicable to the device that focuses or need zoom.
For example: the varifocal mirror of video camera, utilize said apparatus can change focal length at any time, need not use many eyeglasses.
General magnifier can be arbitrarily with the object enlargement factor.Common people wear glasses, and can arbitrarily change the number of degrees, are fit to old man's glasses or spectacles, need not change eyeglass because of the eyes number of degrees change.
The quality of these hydraulic pressure lens is lighter more than 50 percent than glass.Make simply, and make same glass mirror process need consumption mass energy, process is complicated.Be used for the people and wear glasses and to change the focus number of degrees at any time, do not take the eyeglass that often changes the different number of degrees.And usage is simple.
More than a kind of hydraulic pressure lens that the utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; Thought according to the utility model embodiment; The part that on embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
