Anti-interference adapter for optical equipment

The invention discloses an anti-interference conversion connector of optical equipment, which is applied to the field of optical equipment, and is characterized in that a sealing ball with an optical channel, a driven gear, a sealing end cover, a tension spring, an expansion bag body, a limiting ring and an air channel is matched with a machine body assembly and a lens assembly; when the machine body assembly and the lens assembly are separated, the sealing ball can be automatically turned over, so that the sealing end cover can seal the notch in an involution mode, sealing action is completed, when the machine body assembly and the lens assembly are involution, automatic reverse turning can be achieved again, and optical signals collected by the lens assembly can be effectively transmitted to the machine body assembly through an optical channel to complete signal collection. Therefore, when the lens assembly is replaced, the air tightness in the machine body assembly can be always kept, interference factors
