Abstract

The invention provides a lens mechanism, wherein the lens mechanism comprises a sleeve assembly,a first rotating ring and a second rotating ring; the sleeve assembly is provided with a sleeve main body, a first machine part and a second machine part; the first rotating ring is provided with a third machine part and the second rotating ring is provided with a fourth ring; the third machine part is connected to the first machine part in a sliding manner and is limited in the first machine part; and the second machine part is connected to the fourth machine part and is limited in the fourth machine part.

Description

technical field [0001] The invention relates to a lens mechanism. Background technique [0002] In a lens mechanism, the swivel ring is usually used to rotate relative to the lens barrel to perform focusing or zooming operations required for image capturing. Therefore, it is necessary to provide a limiting or locking mechanism that limits the rotation of the swivel within a certain range. For example, if figure 1 As shown, the swivel ring 102 of the lens mechanism 100 can rotate relative to the lens barrel 104 to perform a focusing operation during image capture, and the swivel ring 106 can rotate relative to the lens barrel 108 to perform a zoom operation during image capture. The swivel 102 can be stopped by a positioning post 110 to limit its rotation range, and the swivel 106 can be stopped by a stop screw 112 to limit its rotation range. However, using additional components such as the positioning post 110 and the stop screw 112 as the stop mechanism to limit the rot...
