Description

一种便于调节的接圈及镜头滤镜支架 技术领域
本实用新型属于拍摄设备镜头技术领域，特别涉及一种便于调节的接圈及镜头滤镜支架。
背景技术
目前，现有的照相机、摄影机等拍摄设备在使用过程通常都会在镜头通过滤镜支架安装不同的镜片，以达到不同的效果；现有这些滤镜支架上都设有一个接圈，该接圈上设有可转动的动圈，使用时在动圈上安装有不同的滤镜，如偏振镜、星光镜，以满足不同的光效需求。
实用新型内容
但是，现有这些滤镜支架在使用时还会在其镜片槽上插入镜片，此时该镜片与接圈非常接近，这将导致用户在使用过程中根本无法通过其之间的间隙用手(手指)转动动圈带动滤镜转动，以调整滤镜角度满足不同的光效需求，操作十分困难，简直无法操作，也即完全失去了安装滤镜的作用。
为解决现有技术中存在的上述问题，本实用新型提供了一种只需操作旋转调节旋钮即可驱使动圈转动，从而调整滤镜角度满足不同的光效需求，操作简单、方便、快捷，且结构简单，加工生产容易，具有很强的市场竞争力的便于调节的接圈，以及调用该接圈的镜头滤镜支架。
