一种可调大小的镜头滤镜支架
技术领域
本实用新型属于拍摄设备镜头技术领域，特别涉及一种可调大小的镜 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；但是现有的这些拍摄设备都是采用弹簧夹 结构将其夹紧、 固定在镜头上， 由于采用弹簧夹结构夹紧力过大，极易导 致镜头的塑料外壳变形，影响整体外观，甚至造成镜头损环，工作性能不 稳定、 不可靠。
另外，现有这些滤镜支架只能安装 ND中灰片实现减光功能，不能 360 度旋转，无法实现 CPL滤镜功能，用途单一，通用性差。
实用新型内容
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适用于不 同大小的拍摄设备镜头，结构合理，操作简单，且可避免因夹紧力过大而 导致镜头的塑料外壳变形的问题的可调大小的镜头滤镜支架。
为解决上述技术问题，本实用新型采用如下技术方案：
一种可调大小的镜头滤镜支架，包括有相互连接一体的镜头夹紧座和 镜片安装架；所述镜头夹紧座的内侧侧壁嵌设有活动的两片或两片以上弧 形夹紧件，外侧侧壁设有调节螺纹孔和调节螺杆；所述调节螺杆活动地拧 入调节螺纹孔内，且末端与对应的夹紧件转动连接。
进一步地，所述调节螺杆的末端设有第一环形凹槽，所述夹紧件上设 有转动连接位；所述调节螺杆的末端设于转动连接位内，且夹紧件上设有 第一转动锁定螺丝，所述第一转动锁定螺丝穿过夹紧件且末端设于第一环 形凹槽内。
进一步地，所述夹紧件周向阵列排布地设置在镜头夹紧座的内侧侧壁 上。
进一步地，所述镜头夹紧座与镜片安装架一体成型。
进一步地，所述镜片安装架可 360°旋转地与镜头夹紧座（ 1 )转动连 接一体。
进一步地，所述镜片安装架与镜头夹紧座连接的一端外侧设有第二环 形凹槽，所述镜头夹紧座的相应位置设有第二转动锁定螺丝；所述第二转 动锁定螺丝穿过镜头夹紧座且末端设于第二环形凹槽内。
进一步地，所述镜片安装架的两侧设有对称的多个镜片片夹，多个镜 片片夹的内端设有镜片卡槽。
本实用新型的有益效果是：
本实用新型通过上述技术方案，即可通过手动调节螺杆带动夹紧件向 内端移动或向外端移动，以适用于不同大小的拍摄设备镜头，结构合理， 操作简单，且通过手动操作锁紧，有效避免因夹紧力过大而导致镜头的塑 料外壳变形及夹伤的问题，镜头的工作性能稳定有保障，整体外形美观， 使用极其方便。
另外，可 360°旋转的镜片安装架通过装上高清超薄 CPL偏光片，实 现 CPL偏光功能，功能强大，通用性强，使用也非常灵活，操作同样简单、 方便。
