Embodiment Construction

[0018] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0019] Such as Figure 1-4 As shown, the present invention has a lens cover with shading function, including a hollow main ring 1, which is connected to the lens and detachable; at least a pair of shading members 2 connected to the main ring opposite each other, and can be flipped outwards Open it as a hood, or buckle inward to cover the hollow of the main ring 1 as a lens cover. When the user wants to use the lens cover as a hood, he can manually lift the shading member to a desired angle, and when not in use, he can manually buckle it to protect the lens.

[0020] In one embodiment of the present invention, the main ring 1 is an annular structure with a certain thickness, which is made of high-grade engineering plastics or hardware materials. It includes a joint 11 connected to the lens; a ring part 12 extending outward from the part 11; Th...

Abstract

The invention provides a lens cover with a light-shielding function. The lens cover with the light-shielding function comprises a hollow main ring and at least one pair of light-shielding parts, wherein the hollow main ring is connected with a lens, and the light-shielding parts are oppositely connected with the main ring and can be opened outwards or inwards combined in a buckling mode to shield the hollow position of the main ring. The lens cover is installed on the lens, does not need to be taken down when used, has both a protective function and the light-shielding function, and is convenient to use.

Description

technical field [0001] The invention relates to a lens protection structure, in particular to a lens cover with a light-shielding function. Background technique [0002] The lens is an important component of imaging equipment such as projectors and cameras. It needs to be equipped with a lens cover to protect the front edge of the lens from being damaged by impact, and prevent the mirror surface from being contaminated by dust to ensure image quality. At present, people usually install a lens cap in front of the lens to seal the lens. When shooting or showing, the lens cap is manually removed and put into the pocket, or the lens cap is tied with a rope and hung under the imaging equipment, which is quite inconvenient. If the imaging effect is excellent, you need to install a hood additionally. The traditional lens cap and the lens hood are two accessories independent of each other, and they are carried out at the same time, which increases the burden on the user. Therefor...
