Abstract

The present invention discloses a high-precision constant-speed controllable mechanical zoom ring which comprises an outer cylinder, an inner cylinder, a rotating ring, a convex mirror, a lens fixing frame and a screw, the inner cylinder is slidably connected with the outer cylinder, the rotating ring is rotatably connected with the inner cylinder, one end of the screw is rotatably connected with the inner cylinder, the lens fixing frame is in transmission connection with the screw, the lens fixing frame is in sliding connection with the inner cylinder, when the rotating ring is rotated, the screw rod rotates along with the rotation of the rotating ring, and the screw rod rotates to drive the lens fixing frame to slide in the inner cylinder, so that the position of the convex mirror is adjusted to change the focal length of the lens. The inner barrel and the outer barrel are connected in a sliding manner, so that the position of the inner barrel relative to the outer barrel can be adjusted, the length of the whole lens barrel can be adjusted, the focal length of the lens can be changed, and the zoom range of the zoom ring can be enlarged.

Description

technical field [0001] The invention relates to the technical field of zoom rings, in particular to a high-precision constant-speed controllable mechanical zoom ring. Background technique [0002] The zoom ring is also called a rotating zoom ring, which can change the focal length of the lens to obtain different viewing angle ranges, while the zoom range of the existing zoom rings is relatively small. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-precision constant-speed controllable mechanical zoom ring to improve the zoom range of the zoom ring in view of the above-mentioned defects of the prior art. [0004] In order to achieve the above object, the present invention provides a high-precision fixed-speed controllable mechanical zoom ring, which includes an outer cylinder, an inner cylinder, a rotating ring, a convex mirror, a lens holder and a screw, and the inner cylinder slides with the outer cylind...
