Abstract
The utility model relates to a variable focal length lens, and pertains to the optical instrument fabricating art, which consists of a transparent elastic cavity body, a communicating pipe, a piston cavity and a localizer; wherein, the transparent elastic cavity body is arranged in a circular lens frame and is connected with the piston cavity by the communicating pipe, the localizer is arranged on one side of the piston body. While in use, the piston is pushed as required by the user and is secured by the localizer, the clear liquid in the transparent cavity body would increase or reduce, which would cause change of the focal length of the lens. The model has the advantages of reasonable design, simple structure, high working efficiency and convenient usage.
Description
Technical field
The utility model relates to a kind of zoom lens, belongs to optical instrument manufacturing technology field.
Background technology
The optical lens that general glass is made is a universal focus lens, changes focal length as needs, then needs the combination of many lens, also will have accurate mechanical mechanism to operate, particularly large diameter lens, and the cost height, and use inconvenient.
Summary of the invention
The utility model is at the deficiencies in the prior art, and a kind of reasonable in design, simple in structure, easy to use, lens of variable focal length with stepless focusing function is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of lens of variable focal length, form by transparent elastic cavity, conduction pipe, plunger shaft and steady arm, wherein, the transparent elastic cavity is fixed in the circular picture frame, connect transparent elastic cavity and plunger shaft by conduction pipe, steady arm is located at a side of piston body.
Described transparent elastic cavity is filled high grade of transparency liquid by the transparent elastic film of sealing and is formed.
Described plunger shaft is cooperated with piston by a cylinder body and forms, and there are conduction pipe and the conducting of transparent elastic cavity in the piston lower end, when compression piston, and transparent elastic cavity middle part expansion thickening, the convex lens enlargement ratio increases.
When the utility model uses, according to customer requirements promotion piston and by steady arm fixed piston position, transparency liquid in the transparent cavity increases or reduces, and has changed the focal length of lens immediately, the utlity model has reasonable in design, simple in structure, high efficiency, advantage such as easy to use.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Wherein: 1, transparent elastic cavity, 2, conduction pipe, 3, plunger shaft, 4, steady arm.
Embodiment
Embodiment: structure as shown in drawings, be made up of transparent elastic cavity 1, conduction pipe 2, plunger shaft 3, steady arm 4, wherein, transparent elastic cavity 1 is fixed in the circular picture frame, connect transparent elastic cavity 1 and plunger shaft 3 by conduction pipe 2, the stroke of piston is by steady arm 4 location.During use, according to customer requirements promotion piston and by steady arm 4 fixed piston positions, transparency liquid in the transparent cavity increases or reduces, and has changed the focal length of lens immediately, the utlity model has reasonable in design, simple in structure, high efficiency, advantage such as easy to use.
