Polycyclic filter lens group capable of independently adjusting rotation angle of each lens

Abstract

The invention provides a polycyclic filter lens group capable of independently adjusting the rotation angle of each lens, which comprises a positioning frame body, a first pivoting frame body, a transfer frame body and a second pivoting frame body, wherein each of the frame bodies is a hollow round frame body; one end of the positioning frame body can be positioned to the front edge of a camera lens; a first lens is fixedly arranged at the place, corresponding to the hollow position, inside the first pivoting frame body, one end of the first pivoting frame body is mutually pivoted with the other end of the positioning frame body, and a first arc-shaped surface is arranged along the axial direction on the first pivoting frame body near the other end; a second arc-shaped surface is arranged along the axial direction on the transfer frame body near one end, so as to enable the transfer frame body and the first pivoting frame body to be mutually pivoted through the second arc-shaped surface and the first arc-shaped surface; and a second lens is fixedly arranged at the place, corresponding to the hollow position, inside the second pivoting frame body, and one end of the second pivoting frame body can be mutually pivoted with the other end of the transfer frame body.

Description

technical field [0001] The present invention relates to a multi-ring optical filter group capable of independently adjusting the rotation angles of each lens, especially a filter lens group that can easily pivot a first lens and a second lens to each other or separate them according to the user's needs. , and when the first lens and the second lens are pivotally connected to each other, the angle of the second lens relative to the lens can be adjusted independently, or a filter group that can synchronously adjust the angle of the first lens and the second lens relative to the lens. Background technique [0002] With the rapid development of digital technology, various digital products not only continue to improve in terms of efficacy and performance, but also gradually become popular as the price drops, and penetrate into every corner of people's lives. Digital cameras have the advantages of real-time imaging in use. In addition, because digital storage is used to replace tr...

Problems solved by technology

[0007] In view of the fact that the traditional optical filter sets have defects that need to be improved in many aspects such as purchase cost, carrying, and use, although the inventor has designed a filter called "adjustable light reduction filter" The lens group can effectively improve the various defects of the traditional filter lens group. However, the aforementioned "adjustable light reduction filter" lacks variability and flexibility in the mutual matching between lenses, so there is still room for further improvement.
