Abstract
The utility model relates to a novel zoom lens. Transparent liquids are fully filled in two casing which can correspondingly slide; both sides of each of the casing are covered by elastic transparent films. When the two casing correspondingly slide, the volume in the casing changes to make the liquids in the casings extrude the elastic transparent films on the surface of the lens; therefore, the bending degree of the films changes and focal distances change.
Description
Affiliated technical field
The utility model relates to a kind of zoom lens sheet.
Background technology
In our life at ordinary times, often can see that people hold the camera that has long full length shot and take a picture, cause some unnecessary troubles to portably using like this, and to the influence that also has to a certain degree attractive in appearance of camera.
Summary of the invention
In order to exempt our some unnecessary troubles when taking a picture, make our camera more attractive in appearance.The utility model provides a kind of novel zoom lens sheet.
The technical scheme that the invention for solving the technical problem adopted is: two shells that can slide relatively (each surface has elastic transparent film more) are set, at two envelope filled full transparency liquids.When two shells slided relatively, the volume in the shell changed, and forced the elastic transparent film of liquid extruding lens surface in the shell, the degree of crook of film is changed, thereby change focal length.
Its beneficial effect is: exempt our some unnecessary troubles when taking a picture, make our camera more attractive in appearance.Simple structure has reduced the production cost of zoom lens, promotes the development of zoom lens sheet industry.

Embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
Among Fig. 1, inner casing (3) links together by bayonet socket (4) with shell (5), seals by packer ring (2); Be full of transparency liquid (6) between inner casing (3) and the shell (5); Inner casing (3) can slide relatively with shell (5), and when inner casing (3) opposite shell (5) was slided, the volume in the shell changed, force transparency liquid (6) extruding elastic transparent film (1), change the degree of crook of elastic transparent film (1), thereby change focal length.
Claims (3)
