Abstract
The utility model discloses a linkage opening and closing structure of a flashlight and a lens, which mainly comprises a lens blade, a rotating sheet, a return elastic piece, a transmission mechanism and a motor, wherein, the lens blade is arranged in a front cover; the rotating sheet drives the lens blade to be opened and closed; the return elastic piece enables the lens blade to be returned; and the transmission mechanism and the motor drive the rotating sheet to rotate. One side of the front cover is provided with a flashlight, and the flashlight can be glidingly arranged on one side of the front cover backwards and forwards. A butting surface inclined backwards and forwards is arranged inside the cover body. A flashlight tension spring enabling the cover body to retract is arranged on the flashlight. A butting block corresponding to the butting surface is arranged on one transmission piece, namely the rotating sheet or the transmission mechanism. When the camera starts by the utility model, the flashlight is moved forwards to flush with the lens along with the starting of the lens cover, which guarantees the shooting angle. When the camera is closed, the flashlight retracts along with the closing of the lens cover, which prevents the flashlight from being easily damaged because the flashlight protrudes out of the lens surface.
Description
Technical field
The utility model relates to a kind of camera or video camera, refers to a kind of flashlamp and lens cap interlock on-off structure that is applied to camera or video camera especially.
