Abstract

The invention discloses a lens filtering device. The device comprises a base, a switching sheet, a switching driving mechanism and an upper cover; the lens is fixedly connected through a lens connecting hole in the base; a first light filter and a second light filter are arranged on the switching sheet; the switching driving mechanism acts on the switching sheet to switch the first light filter and the second light filter. The lens filtering device has the advantages that the structure is simple, few parts are used, the filtering stability of the switching sheet can be improved, and meanwhile, switching sheet can be conveniently assembled to a lens.

Description

【Technical field】 [0001] The invention relates to a lens assembly, in particular to a lens filter device. 【Background technique】 [0002] Now on the market, the switching device used for the lens is generally made into a drawer-like structure, and the thickness of the front end is extremely thin, within 2mm. Therefore, the switching device is prone to deformation or damage during transportation or assembly; the entire The switching device is fixedly connected to the base by screws. Due to the adoption of the above-mentioned design structure, there are many components, which increases the corresponding design and manufacturing costs such as mold opening costs. [0003] The present invention studies and proposes aiming at the deficiencies in the prior art. 【Content of invention】 [0004] The technical problem to be solved by the present invention is to provide a lens filter device, which includes a base, a switching piece, a switching drive mechanism and an upper cover. Th...
