Description

Technical Field

[0001] The utility model relates to the technical field of filter mounting devices, in particular to a multifunctional optical component mounting device. Background Art

[0002] A filter is an additional lens installed in front of the camera lens to filter natural light. Filters are often needed when shooting outdoors.

[0003] After searching, the patent number is CN213240768U, and the name is a utility model of a portable camera filter fixing device, which includes a flexible fixing ring. Through research and analysis, it is found that although it has the advantages of simple structure, easy operation, and the fixing device can be adjusted according to the size of the filter during use, and it is easy to carry, etc., it still has the following disadvantages to a certain extent.

[0004] Without the shading function, the above device cannot block the sunlight during the shooting process, which makes it easy for the sunlight to shine on the surface of the filter, and then easily affects the subsequent film-forming effect, and cannot meet the needs of users. In order to solve the above technical problems, we have designed a filter installation device that is easy to adjust the filter.

[0005] The existing publication number is CN220709515U, which discloses a filter installation device that is easy to adjust the filter, including a cylinder, a placement rack is riveted at the bottom of the front side of the cylinder, the inner cavity of the placement rack is placed with a filter body, a groove is opened at the top of the cylinder, and both sides of the inner cavity of the groove are opened with a slide groove, the inner cavity of the slide groove is slidably connected with a limiting mechanism, the top of the cylinder is movably connected with a shell, the inner cavity of the shell is movably connected with a light shield, the light shield is located at the top of the filter body, and the limiting mechanism includes a slider, the slider is located in the inner cavity of the slide groove, and the opposite side of the slider is riveted with a limiting plate. The utility model has the advantage of shading function through the cooperation of the shell, the light shield, the positioning bolt, the positioning groove, the Velcro velvet surface and the Velcro adhesive surface, and can block sunlight, so that the sunlight is not easy to irradiate the surface of the filter body, thereby improving the subsequent imaging effect.

[0006] However, the above-mentioned improved patent still has certain shortcomings. For example, when shooting, people may hold the camera sideways to frame the scene. In this case, the existing structure has a poor shading effect, and the shading function is single and inconvenient to adjust. In addition, small structures such as designed springs increase the difficulty of assembly. Utility Model Content
