Title:
SINGLE-FOCUS LENS WATERPROOF STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2018/218892
Kind Code:
A1
Abstract:
A single-focus lens waterproof structure, comprising: a lens barrel (1) for constituting a lens body, a frontmost lens (2) to be mounted at the frontmost end of the lens barrel (1), and a waterproof gasket (3) for waterproofing. The lens barrel (1) is provided with a mounting position for mounting the frontmost lens (2). When the frontmost lens (2) is mounted at the mounting position, the waterproof gasket (3) is disposed between the outer side edge of the frontmost lens (2) and the inner side wall of the lens barrel (1), thereby eliminating the acting force applied to lenses in the direction of the optical axis so that a spacing between lenses is more susceptible to control.
