Technical Problem

上述结构在拆卸压盖以及前端镜片后,O型圈为活动的,有丢失的风险;且用户在拆卸前端镜片并进行更换时,由于O型圈可动,导致在安装新的前端镜片时O型圈位置有发生移动的风险,进而导致安装前端镜片后结构密封性能变差

Benefits of technology

[0016]本实用新型提供的定焦鱼眼镜头,通过将密封圈朝向环形安装槽槽底的一侧设置为第一平面,并在第一平面设置胶层,使得密封圈在安装时能够通过胶层粘接于环形安装槽的槽底,使得当前端镜片在拆卸时能够保证密封圈固定不动,避免掉出镜框;且将密封圈朝向环形安装槽槽底的一侧设置为平面结构利于增大胶层的面积,使得粘接牢固,还能够提高密封性能,使得该定焦鱼眼镜头满足防水气密性要求。
