Description

一种带防脱落功能的固定装置及具有其的舞台灯光学装置 技术领域
本发明涉及舞台灯技术领域，更具体地，涉及一种带防脱落功能的固定装置及具有其的舞台灯光学装置。
背景技术
在舞台灯光技术领域中，为了实现丰富的舞台灯光效果，通常需要使用到各种光学元件，如图案片、棱镜片等，而为了方便维护，这些光学元件一般采用可插拔的结构设计。现有的棱镜装置一般采用如下结构：棱镜装置通常包括棱镜主体、棱镜座、棱镜组件支架、棱镜座挡板、棱镜座插拔定位结构，棱镜主体装设在棱镜座上，棱镜座上设有限位凸台，棱镜座插进棱镜组件支架后，靠棱镜座插拔定位结构、棱镜座挡板和限位凸台一起作用将所述棱镜座固定。但由于现在对灯具的运输条件越来越严格的情况下，这种结构难以完全保持棱镜主体及棱镜座在运输过程中不会脱落，为了解决这个问题，现有技术中，很多情况下只能是把棱镜座插拔定位结构做得更紧，或者把棱镜挡板做得更高，或者把棱镜限位凸台做得更高，虽然这种技术能够改善脱落情况，但会引起拆装困难，使得可插拔的结构设计不会发挥作用，变成一种摆设。
发明内容
本发明为克服上述现有技术所述的至少一种缺陷，提供一种带防脱落功能的固定装置及具有其的舞台灯光学装置。本发明结构简单，使用方便，可解决舞台灯中可拔插的光学组件易脱落的问题，且能实现易于插拔的效果。
