Abstract

The present invention relates to a zoom lens comprising a fixed base, a driving wheel and at least two lens chambers; wherein the fixed base is provided with a containing hole extending along an optical axis; the driving wheel takes the optical axis as an axle center and is rotatably arranged on the fixed base; the lens chambers are movably arranged in the containing hole of the fixed base along the optical axis; and at least one lens chamber is connected with the driving wheel. By adopting the above structure, when the driving wheel rotates relative to the fixed base, the lens chambers can be driven to close to or separate from each other in the fixed base, thereby achieving the effect that the integral structure is stable during moving.

Description

technical field [0001] The invention relates to a lens, in particular to a zoom lens. Background technique [0002] The development of digital imaging technology is changing with each passing day. In addition to the pursuit of high-pixel imaging and high-resolution output, electronic devices equipped with digital imaging must also have technical characteristics such as faster operation speed and smaller size. For example, equipment such as digital cameras or projectors, in order to be convenient for operators to use in various environments, it is often necessary to achieve a design that minimizes the volume and maximizes the performance. [0003] The lenses of existing digital cameras or projectors and other equipment usually have the function of adjusting the focal length, such as Figure 5 and Figure 6 As shown, the known lens usually has a front group mirror chamber 72 and a rear group mirror chamber 74 arranged in the fixed seat 70, and the two mirror chambers 72, 74 a...
