Specific embodiment
The technical scheme of this patent is described in more detail with reference to specific embodiment.
Refer to Fig. 1-2, a kind of diaphragm governor motion, including fixed outer cylinder 1, diaphragm adjustment barrel 2, time fitted tube 3, manual light
Door screen 4, main cylinder 5, mobile group 6, driving lever 8 and Ya Fu groups 9, the manual diaphragm 4 are fixed on left side inside mobile group 6 simultaneously
And fixed using fastening screw 7, revolving drum 3 is enclosed within the left side outside mobile group 6, and mobile group 6 inserts the left side of main cylinder 5,
Ya Fu groups 9 screw in the left side of mobile group 6 and Ya Fu groups 9 are located at the left side of manual diaphragm 4, and diaphragm adjustment barrel 2 is enclosed within
Outside main cylinder 5, driving lever 8 is arranged in the screwed hole of diaphragm adjustment barrel 2, and driving lever 8 passes through the escape groove of main cylinder 5 and inserts revolution
The straight trough of cylinder 3, fixed outer cylinder 1 is fixed on the left side of main cylinder 5 through diaphragm adjustment barrel 2 and fixed outer cylinder 1.Fixed outer cylinder 1 leads to
Cross screw thread to be connected with main cylinder 5, Ya Fu groups 9 are connected through a screw thread to be fixed with mobile group 6.Boss is provided with main cylinder 5, is turned round
An elongated slot and a groove are provided with cylinder 3, lobe plate is provided with manual diaphragm 4, lobe plate is stuck in the groove of revolving drum 3
It is interior.The quantity of fastening screw 7 is two.
Operation principle of the present utility model is：Manual diaphragm is opened and closed the realization of regulatory function：Left-right rotation diaphragm adjustment barrel
2, the driving lever 8 for making lock pay in diaphragm adjustment barrel 2 stirs revolving drum 3, and the revolving drum 3 of rotation drives the diaphragm snapped in its groove convex
Wheel plate left-right rotation, so as to realize that diaphragm bore becomes regulatory function that is big and reducing.The erection sequence of the device is as follows：By hand
Dynamic 4 groups of diaphragm enters mobile group 6, then locks and pay 2 fixed apertures of fastening screw 7, then by revolving drum 3 groups enter the good manual diaphragm of group
In 4 mobile group 6, and the lobe plate of manual diaphragm 4 is snapped in the straight trough of revolving drum 3, then Ya Fu groups 9 are screwed into movement
On the screw thread of group 6 and lock and pay in place, then become owner of cylinder 5 by above-mentioned overall group, then diaphragm adjustment barrel 2 groups become owner of on cylinder 5, so
Driving lever 8 is screwed into the screwed hole of diaphragm adjustment barrel 2 afterwards, through the escape groove of main cylinder 5, is inserted in the straight trough of revolving drum 3, finally
Fixed outer cylinder 1 is screwed in into main cylinder 5, so that the axial movement of snoot adjustment barrel 2.The boss that diaphragm adjustment barrel 2 passes through main cylinder 5
Its axial movement is limited with fixed outer cylinder 1, fixed outer cylinder 1 is to be connected through a screw thread with main cylinder 5, and the side wall of diaphragm adjustment barrel 2 has
Countersunk screw holes at one, countersunk screw holes are used for locking pays driving lever 8.There is boss on main cylinder 5 to limit the axial direction shifting of the late adjustment barrel 2 of light modulation
Dynamic, main cylinder 5 has an escape groove in addition, and escape groove enables driving lever 8 to be inserted through main cylinder 5 in the straight trough of revolving drum 3, and this is kept away
Allow groove circumferential angle will with need diaphragm adjust angle it is consistent, i.e., this groove will be used for spacing, the diaphragm at one end of groove of driving lever 8
Bore reaches maximum, and the diaphragm bore in the other end of groove of driving lever 8 reaches minimum.The center of revolving drum 3 empty for horde
Group 6 coordinates, and side wall has at one groove at elongated slot and, and elongated slot is used for coordinating driving lever 8, and driving lever 8 is together when rotating diaphragm adjustment barrel 2
Rotate, driving lever 8 is dialled revolving drum 3 and rotated, another function of elongated slot is can to avoid moving dry with driving lever 8 when group 6 moves axially
Relate to, the groove of revolving drum 3 blocks the lobe plate of manual diaphragm 4, drive diaphragm bore to become big or reduce when revolving drum 3 is rotated.Return
Rotating cylinder 3 is coordinated by the path with mobile group 6, and end face breasting, the other end Shi Yafu groups 9 of revolving drum 3 can limit
System axial movement.4 groups of manual diaphragm enters mobile group 6, and is locked by 2 fastening screws 7 and pay fastening, the manual diaphragm 4 it is convex
Wheel plate does not need cantilever, can greatly improve Shot intense, lifts quality.The device avoids groove sidewall using driving lever 8 with main cylinder 5
Spacing to control the anglec of rotation, so as to lift the intensity of whole camera lens, main cylinder 5 avoids the angle of the v-groove, and to be necessarily less than manual diaphragm 4 convex
Wheel plate rotational angle.
The device is reasonable in design, and simple structure, fault rate is low, safety in utilization and good operation stability；The device is consolidated
Determine outer barrel 1, mobile group 6 and Ya Fu groups 9 can be designed to fill the group of eyeglass or not fill eyeglass according to optical system
Connecting cylinder, it is applied widely；The device is easy to process, and convenient disassembly, low production cost, use intensity is high, stable drive.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can in other specific forms realize that this practicality is new
