Embodiment Construction

[0045] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.

[0046] The present invention is a multi-ring filter lens group that can independently adjust the rotation angle of each lens, please refer to figure 2 and image 3 As shown, the filter set 10 is applied to a camera lens 20 (such as figure 1 shown), and can be mounted to a camera 30 along with the camera lens 20 (such as figure 1 shown). In the first preferred embodiment of the present invention, the filter set 10 includes a positioning frame 11, a first pivot frame 12, a transition frame 13 and a second pivot frame 14, The frames 11-14 can be made of metal, plastic steel or plastic. The positioning frame 11 is a hollow circular frame. A positioning ring 111 protrudes from one end thereof along the axial direction, and a firs...

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...
