A lens locking and dismounting mechanism and method

Abstract

The invention belongs to the field of machinery, and discloses a lens locking and dismounting mechanism and method. The mechanism includes a lens barrel mounting seat provided with a first fitting part, an elastic locking piece, and an elastic locking piece sleeved outside the elastic locking piece. The lens locking sleeve is provided with a second matching part, and the second matching part is movably connected to the first matching part so that the lens locking sleeve can move along the locking direction and the unlocking direction , when the lens locking sleeve moves along the locking direction, it can push against the elastic locking member, so that the elastic locking member provides holding force; the method is to adjust the lens locking sleeve so that the The lens locking sleeve pushes against the elastic locking member so that the elastic locking member provides holding force, so as to realize the fixing and dismounting of the lens assembly. The invention can realize the convenient replacement and locking of the lens assembly and the fast focusing function of the lens assembly without causing the deviation of the optical axis direction of the lens assembly.

Description

technical field [0001] The invention belongs to the mechanical field, and more specifically relates to a lens locking and dismounting mechanism and method. Background technique [0002] At present, when the lens assembly is installed and locked on the lens mount, the thread fit method is usually used to screw the lens assembly into the lens barrel mount, and then rotate and adjust the position of the lens assembly until the image is clear to realize the focusing process of the lens , and then lock the lens assembly on the lens barrel mount by tightening the locking nut on the outer ring of the main lens barrel of the lens assembly. Often in order to ensure the stability and reliability of the lock nut, it is necessary to tighten the set screw on the outer ring of the lock nut to tighten the lock nut and limit its movement. On the contrary, when disassembling or replacing the lens assembly, it is necessary to loosen the set screw first, and then unscrew the locking nut, so t...
