Technical Field

[0001] The utility model relates to the technical field of camera lenses, and specifically relates to a camera lens that is convenient to disassemble. Background Technique

[0002] A camera is a device that uses the principle of optical imaging to capture and record images, mainly used for photography. It focuses light through a lens and forms an image on a photosensitive material or digital sensor. A camera includes several basic components: a lens, an aperture, a shutter, a photosensitive element (such as film or a digital sensor), and a system for controlling exposure. The lens is the core component of the camera, responsible for focusing light on the photosensitive element, the aperture controls the amount of light entering the camera, and the shutter controls the time that light shines on the photosensitive element.

[0003] During the use of the camera, in order to improve the protection of the lens on the lens, a front lens of the lens is generally installed on the lens barrel, so that when the camera is impacted or dropped, the external force acts on the front lens to avoid damage to the internal lens. However, when replacing the front lens, since its surface is generally provided with a sealing edge for fixing, a spatula needs to be used to remove it, the operation is relatively cumbersome, and it has a certain danger.

The mounting plate 17 and the front lens 23 of the lens are installed in the positioning groove 12 through the positioning block 18, and the position of the mounting plate 17 is fixed through the fixing bumps 19. The protective rubber ring 16 is installed in the mounting hole 14 through the mounting post 15, and the stability of the connection is increased through the special-shaped circular magnet. When it is necessary to disassemble the front lens 23 of the lens, the protective rubber ring 16 is pulled upward to separate the mounting post 15 from the mounting hole 14, the protective plate 10 is pulled to both sides to separate the connecting block 9 from the groove 8, and the protective plate 10 is removed from the lens barrel 1. The rotating plate 7 is rotated to make the threaded rod 5 rotate in the threaded hole 3, and the control block 6 is pushed to slide in the mounting groove 4. The control block 6 contacts the guiding grooves 22 on the first limiting block 20 and the second limiting block 21.
