Lens barrel for mounting lens piece and lens piece looseness prevention camera

Abstract

The invention provides a lens barrel for mounting a lens piece. The lens barrel comprises a lens barrel body of a hollow barrel-shaped structure; the lens barrel body comprises a resisting part, a first barrel wall, a second barrel wall and a third barrel wall; the resisting part is used for resisting against the end surface of the lens piece; the first barrel wall and the resisting part form a limiting structure of the lens piece; the resisting part, the first barrel wall, the second barrel wall and the third barrel wall are arranged in sequence along an axial direction of the lens barrel body; the first barrel wall, the second barrel wall and the third barrel wall form an outwards expanded step shape; the second barrel wall and the third barrel wall are provided with connection structures, so that a second gland nut mounted on the third barrel wall presses a first gland nut mounted on the second barrel wall. The invention further relates to a lens piece looseness prevention camera. Since two gland nuts are used to press the lens piece, the lens piece cannot be loosened and is ensured to be stable, and efficient and stable work of the camera is guaranteed. The lens barrel is ingenious in structure and reasonable in design, and is convenient for popularization and application to the field of optical cameras.

Description

technical field [0001] The invention belongs to the field of optical lenses, and in particular relates to a lens barrel for installing lenses and a lens for preventing loosening of lenses. Background technique [0002] Optical lens is an important part in the field of machine vision, and is widely used in all aspects of machine vision image acquisition. With the increasing degree of automation, the application scene of the lens gradually changes from static to high-speed moving components; but when the lens moves with When the module executes the movement command, the compressed lens in the lens will gradually loosen due to inertia or mechanical vibration. After a long time running, image acquisition deviation will easily occur, and the lens will easily loosen or even fall off. [0003] In this regard, it is urgent to improve the existing lens barrel structure, optimize its structural design, and design a new type of lens with anti-loosening structure to solve the above prob...

[0002] Optical lens is an important part in the field of machine vision, and is widely used in all aspects of machine vision image acquisition. With the increasing degree of automation, the application scene of the lens gradually changes from static to high-speed moving components; but when the lens moves with When the module executes the motion command, the compressed lens in the lens will gradually loosen with inertia or mechanical vibration, and the image acquisition deviation will easily occur after long-term operation. At the same time, the lens is prone to loosening or even falling off.
