Abstract

The invention discloses a lens hood mechanism and a photographic device. The lens hood mechanism comprises a lens hood, a first lens cone and a second lens cone. One end of the peripheral outer edge of the lens hood protrudes and extends to form at least three guiding protruding points, the first lens cone is arranged outside the lens hood in a sleeved mode, at least three cone grooves are formed in the positions, corresponding to the guiding protruding points, of the peripheral inner edge of the first lens cone, the guiding protruding points are embedded into the cone grooves respectively, one end of the peripheral outer edge of the first lens cone protrudes and extends to form at least three guiding protruding blocks, the second lens cone is arranged outside the first lens cone in a sleeved mode, and at least three ribs are arranged at the positions, corresponding to the guiding protruding blocks, of the peripheral inner edge of the second lens cone. Accordingly, the second lens cone rotates to drive the first lens cone to rotate, and therefore axial displacement is achieved for the lens hood, and the function of automatically folding the lens hood is achieved.

Description

technical field [0001] The invention relates to a light shield mechanism and an imaging device thereof, in particular to a light shield mechanism capable of automatically storing a light shield and an imaging device thereof. Background technique [0002] With the evolution of the times, people have become accustomed to taking pictures to record their lives. In order to make the photos taken more realistic or more beautiful, many people will install a hood in front of the lens of the camera to reduce the diffraction of light when taking pictures, thereby improving the image quality. [0003] However, in order to avoid glare and other phenomena when taking pictures, the hood is usually installed on the camera lens in an additional way, and often in the process of installing the hood, the most memorable moment has been missed, and the installation of the hood The process will cause inconvenience to the photographer. Furthermore, since the hood is an unnecessary component when...
