Description

Technical Field

[0001] The utility model relates to the technical field of zoom lenses, in particular to a sealing structure of a zoom lens. Background Art

[0002] A zoom lens is a camera lens that can change its focal length within a certain range, thereby obtaining different widths of field angles, different sizes of images, and different ranges of scenery. A zoom lens can change the shooting range by changing the focal length without changing the shooting distance, so it is very helpful for picture composition. Since a zoom lens can also serve as several fixed-focus lenses, it not only reduces the amount of photographic equipment carried when traveling, but also saves time for changing lenses.

[0003] For example, the announcement number is CN216310370U, and the name of the Chinese authorized patent is (a zoom lens structure), which includes: a housing, a frame located in the housing, a guide structure and a drive structure, wherein a lens is installed in the frame, the frame includes a front frame and a rear frame, the guide structure includes two guide rods arranged parallel to the axis of the housing, the front frame and the rear frame are slidably installed on the two guide rods, the drive structure includes two drive units for driving the front frame and the rear frame respectively, the drive unit includes a pulley, a screw rod and a motor for driving the screw rod to rotate, the pulley is fixed on the front frame or the rear frame, and a rack is provided on the pulley, and the rack is meshed with the screw rod. The zoom lens structure of the utility model has a reasonable layout, a compact structure, a total length of the lens <45mm, a small overall volume, and is easy to install and use. At the same time, it adopts an integrated screw rod structure to drive the zoom, so that the lens can be quickly changed and focused when used, and the noise is also small.

[0004] However, the existing variable focus lens has the problem of complicated operation when installing and removing components; therefore, it does not meet the existing needs. In this regard, we propose a sealing structure for a variable focus lens. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
