Abstract

The invention discloses an inclination angle adjusting structure, a lens assembly and photographic equipment, and the inclination angle adjusting structure comprises a fixed part, a floating part, a plurality of rolling supporting bodies, a magnetic attraction structure, and a height adjusting structure. The floating piece and the fixed piece are oppositely arranged, and one of the floating piece and the fixed piece is a bearing mounting piece; the plurality of rolling support bodies are arranged on the bearing mounting piece, are positioned between the fixed piece and the floating piece and are used for supporting the floating piece on the fixed piece, and at least part of the plurality of rolling support bodies are arranged as height-adjusting rolling support bodies; the magnetic attraction structure is arranged between the fixed part and the floating part; the height adjusting structure is arranged between the bearing mounting piece and the height-adjusting rolling supporting body and is used for adjusting the height of the height-adjusting rolling supporting body protruding out of the bearing mounting piece; the height adjusting structure is used for adjusting one or more height adjusting rolling supporting bodies so as to correct inclination of the lens, correction operation is simple and easy to achieve, correction efficiency is improved, and therefore production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of photographic equipment, in particular to an inclination angle adjustment structure, a lens assembly and photographic equipment. Background technique [0002] Lenses are used in existing photographic equipment. Taking the zoom lens as an example, the zoom lens has a fixed lens group and a moving lens group. The lens focus is realized by moving the moving lens group. Errors and assembly errors make the fixed lens and the moving lens tilt at different angles, which reduces the focusing accuracy of the zoom lens. Contents of the invention [0003] The present invention mainly proposes an inclination angle adjustment structure, lens assembly and photographic equipment, aiming to solve the problem of lens inclination in existing lenses due to part size errors or assembly errors. [0004] The main purpose of the present invention is to propose a tilt angle adjustment structure, comprising: [0005] Fastener;...
