Adjustable multi-ring polarizing and dimming lens group axially located through elastic embedding and locking component

Abstract

The invention discloses an adjustable multi-ring polarizing and dimming lens group axially located through an elastic embedding and locking component, the adjustable multi-ring polarizing and dimminglens group comprises a fixed connection ring and a first pivot joint ring, wherein a first polarized lens is fixedly arranged in the fixed connection ring, one end of the fixed connection ring can befixed to a front edge of a camera lens through screw joint, an end face of the other end of the fixed connection ring is concavely provided with at least one accommodating groove along an axial direction, the elastic embedding and locking component is mounted in the accommodating groove, under an own elastic force, the elastic embedding and locking component enables a free end thereof to be exposed outside the accommodating groove, or under an external force, the free end thereof can be embedded in the accommodating groove; a second polarized lens is fixedly arranged in the first pivot joint ring, one end of the first pivot joint ring is connected to the other end of the fixed connection ring through pivot joint, and the end face is provided with an abut-against part in a circumferential direction, thus, the free end of the elastic embedding and locking component can be abutted against inside of an abutting groove concavely arranged in the abutting part. So, an effect of different dimming quantity can be generated, and the dimming effect is enabled to be not deviated under a condition of shaking.

Description

technical field [0001] The present invention relates to a multi-ring polarizing and light-reducing lens group, especially an adjustable multi-ring polarizing and light-reducing lens group that is axially positioned by elastic inserts, so that the two polarizing lenses set therein can be adjusted according to the user's requirements. They rotate relative to each other to easily adjust different light reduction amounts and position the light reduction amount firmly at the required light reduction value, thereby effectively improving the convenience, accuracy, stability and practicality of use. Background technique [0002] With the rapid development of digital technology, all kinds of digital products not only continue to improve in terms of efficacy and performance, but also gradually become popular as the price drops. Here is the current digital camera as an example. Due to its advantages of real-time imaging, Moreover, the images are stored digitally, which not only enables...

[0006] For a long time, in addition to using the "three-ring polarizing light-reduction lens group" personally, the inventor also actively shared various photography experiences and experiences with related common fans. During the aforementioned process, he found that although the aforementioned "three-ring The polarized light reduction lens set" not only allows consumers to freely adjust the passing rate of incident light, but also has the effect of polarizing filters to filter specific polarized light. However, consumers do not need to adjust the amount of light reduction in most shooting environments , and only want to adjust the passing angle of specific polarized light, in order to effectively eliminate the reflection on the surface of the subject (such as: water surface, window glass or plant leaf surface), and obtain the ideal shooting effect. However, when using the
