Description
Technical field
The utility model is related to a kind of manual diaphragm structures of dual extension amount of movement.
Background technology
As camera lens is universal on projecting apparatus, industrial detection, intelligent transportation, scanning and copying device and photographic camera
Using, and needing to adapt to camera lens the demand of different object distances, it is desirable that camera lens has focusing function, and focus eyeglass group and diaphragm one
Mobile focusing is played, particularly telephoto lens, eyeglass group mobility amount are big.The movement of the big stroke of diaphragm certainly will cause lens construction empty
Between it is insufficient.
It is also more and more urgent for a kind of demand for the structure that may extend away diaphragm shift motion in shorter space, especially tie
Structure is simply flexible, at low cost, is convenient to mount and dismount diaphragm regulating mechanism.
Utility model content
The purpose of this utility model is to provide a kind of manual diaphragm structure of dual extension amount of movement, to solve the above-mentioned back of the body
The camera lens proposed in scape technology is right on photographic camera, industrial detection, intelligent transportation, scanning and copying device and photographic camera
Diaphragm big stroke movement needs of problems when burnt.
To achieve the above object, the utility model provides following technical solution：
A kind of manual diaphragm structure of dual extension amount of movement, is made of start slot, plumbing arm and lobe plate, and main body is formed such as
Under：Manual diaphragm with plumbing arm and the diaphragm adjustment barrel with start slot.
As further program of the utility model：The lobe plate plumbing arm of the manual diaphragm with plumbing arm is caught in diaphragm
In the start slot of adjustment barrel, rotation diaphragm adjustment barrel adjusts diaphragm caliber size, and the manual diaphragm with plumbing arm is consolidated with eyeglass group
Fixed to move up and down focusing together, when lens imaging focusing amount of movement requirement is big, the lobe plate of diaphragm is detached from diaphragm adjustment barrel
Start slot, transmission can still be realized by being caught in start slot by diaphragm plumbing arm end at this time.
Compared with prior art, the beneficial effects of the utility model are：It is simple in structure that flexibly low cost is convenient to mount and dismount, turn
It is dynamic steady, the mechanism of big stroke movement can be realized in smaller space, the realization of the structure function of each camera lens is facilitated, is hung down by band
The manual diaphragm cantilever of arm and the flute length extension diaphragm of diaphragm adjustment barrel and the start cooperation length of diaphragm adjustment barrel with start slot
Degree effectively reduces space, the structure of dual extension diaphragm shift motion, suitable for simple group optical focusing, the optics of whole group focusing
Lens mechanism, amount of movement of especially focusing is big, the camera lens that diaphragm is moved together with eyeglass group.
Description of the drawings
Fig. 1 is the manual diaphragm transmission mechanism schematic diagram of the utility model.
Fig. 2 is the irrealizable location status of traditional diaphragm drive mechanism.
Fig. 3 is the mechanism of diaphragm schematic diagram with plumbing arm of the utility model.
Fig. 4 is the structure diagram of the diaphragm adjustment barrel with start slot in the utility model.
In figure：1- starts slot, 2- plumbing arms, 3- lobe plates.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
Referring to Fig. 1, in the utility model embodiment, a kind of manual diaphragm structure of dual extension amount of movement is dual to prolong
It stretches and refers to 1 flute length of start slot and the length cooperation extension diaphragm amount of movement of diaphragm plumbing arm 2, it is irrealizable traditional structure can be used in
The camera lens that diaphragm amount of movement is big, space is limited is a kind of section space-efficient new structure.
A kind of manual diaphragm structure of dual extension amount of movement, is made of start slot 1, plumbing arm 2 and lobe plate 3,
Main body composition part is as follows：Manual diaphragm with plumbing arm 2, (referring to Fig. 3, this diaphragm is fixed with eyeglass group, when imaging is focused
Diaphragm need to be moved up and down with imaging system), the diaphragm adjustment barrel with start slot 1, (please referring to Fig. 4).
A kind of function of manual diaphragm structure of dual extension amount of movement is realized：The lobe plate 3 of manual diaphragm with plumbing arm 2
Plumbing arm 2 is caught in the start slot 1 of diaphragm adjustment barrel, and rotation diaphragm adjustment barrel adjusts diaphragm caliber size, realizes that diaphragm adjusts work(
Can, the manual diaphragm with plumbing arm 2 fixes with eyeglass group and moves up and down focusing together, when lens imaging focusing amount of movement requirement is big
When, the lobe plate 3 of diaphragm is detached from the start slot 1 of diaphragm adjustment barrel, is caught in start slot 1 by 2 end of diaphragm plumbing arm at this time and still may be used
Realize transmission；Be that plumbing arm 2 and start slot 1 are used with merging in place of its novelty, increase cooperation actuating travel, be especially suitable for camera lens into
The lens construction of camera lens up-down structure part insufficient space as mobile focusing stroke length.
The utility model is not limited to above-described embodiment, on the basis of technical solution disclosed in the utility model, this
For the technical staff in field according to disclosed technology contents, not needing to performing creative labour can be to some of which technology spy
Sign makes some simple modification, equivalent change and modifications, belongs in the range of technical solutions of the utility model.
In the description of this specification, it should be noted that unless otherwise clearly defined and limited, term " setting ",
" connected " and " connection " should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected or integrally connect
