Description

Technical Field

[0001] The utility model belongs to the technical field of photographing devices, and particularly relates to a light shielding structure for photographing devices. Background Art

[0002] When an autofocus camera is in use, when sunlight shines directly onto the camera from the side, the intensity of sunlight far exceeds the camera's light sensitivity, which will cause the camera to be unable to properly expose. In this case, the captured image may have spots, color casts, or overexposure, affecting image quality.

[0003] In the prior art, some cameras are equipped with lens hoods. However, since the hoods are cylindrical in shape and have a large shielding range, they can easily darken the four corners of the photo, affecting the image acquisition quality. Furthermore, when taking a snapshot, if the hood is not installed on the camera, the photographer can only use his hands, paper, etc. to block it, which is a cumbersome operation.

[0004] Therefore, it is necessary to propose a light shielding structure for a photographing device to solve the above problems. Utility Model Content

A toothed ring 6 is arranged outside the circular ring 5, and the toothed ring 6 surrounds the outside of the circular ring 5, and an annular groove 7 is formed between the circular ring 5 and the toothed ring 6.
