Lens Cover

Abstract

A lens cover for a lens equipment includes a tubular cover body for detachably coupling at a lens housing of the lens equipment in front of a lens thereof, a cover module, and a locking mechanism. The cover module includes a cover panel and a joint unit coupled between a sidewall of the cover body and a peripheral edge of the cover panel to enable the cover panel to be moved between a covered position and an uncovered position, wherein in the covered position, the cover panel is supported at a front portion of the cover body for covering the lens, and in the uncovered position, the cover panel is rotated sidewardly about the joint unit for uncovering the lens. The locking mechanism is provided at the sidewall of the cover body for releasably locking the cover panel in the covered position.
