Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail.
A kind of manual iris of industrial lens, manual focusing structure, comprise body 8, aperture assemblies and focusing ring 1, described aperture assemblies is coaxially movably arranged in body, and the outer rim of described focusing ring is threaded with body, and the Inner circle of this focusing ring is threaded with aperture assemblies.
In the present embodiment, described aperture assemblies comprises moving body 2, six aperture blades 3, packing ring 4, end cap 6 and aperture ring 9, aperture blades is coaxially installed with successively in described moving body, packing ring and end cap, the structure of described aperture blades as shown in Figure 2, its side, upper surface is fixedly mounted with upper guide post 3A, its lower surface opposite side is fixedly mounted with lower guide pillar 3B, the through hole that described upper guide post is shaped with annulus in moving body is flexibly connected, described lower guide pillar is inlaid in the guide groove that packing ring circumference is shaped with, the side one bending downwards of this packing ring is shaped with connecting portion 4A, this connecting portion is threaded pin 5, the outside of this pin is positioned at the elongated slot 2A that moving body bottom is shaped with, stir pin to make packing ring rotation thus realize aperture blades to open, the object of closing.Described end cap screw thread is arranged on the bottom of moving body, and the bottom of this end cap radial direction installs tommy 7, and the outer end of this tommy is positioned at open slot 2B that moving body lower edge is shaped with and the axial long hole 8A that body side axis is shaped with.
The outer rim of described moving body is set with aperture ring, and loading ring 12 is coaxially installed in this aperture ring bottom, and this loading ring and body are solidly installed.The upper end of described aperture ring and the bulge loop top of body outer rim force together, and the bottom of this aperture ring is coaxially pushed up and is pressed in loading ring upper surface.As shown in Figure 3, this aperture ring inner circle is shaped with holds the axial elongated slot 9B of described pin to the structure of described aperture ring, by rotating light ring realize adjustment aperture blades open and object.In the process of rotating light ring, axially spacious amount is produced when rotating to prevent aperture ring, the bottom of described aperture ring is axially shaped with a counterbore 9A, coaxial installation one spring 10 in this counterbore, pressure one steel ball 11 is pushed up between this spring and loading ring end face, by spring and steel ball be arranged so that aperture ring rotates time not only eliminate axially spacious amount, and stability of rotation, effectively improve the image quality of camera lens.
The mounting means of described loading ring and body is: pressure ring 14 is coaxially installed in the bottom of loading ring, and loading ring compresses and links together with body coaxial threaded by this pressure ring, in order to prevent loading ring from rotating, is provided with register pin 13 between this loading ring and body.
