Specific embodiment
The present embodiment is the preferred embodiments of the present invention, other its all principles and basic structure are identical as the present embodiment
Or it is approximate, within scope of protection of the utility model.
The iris ring Installation practice of the double drive of the utility model is referring to Fig.1 shown in -5, including fixing seat 1, installation
Blade driving assembly and transfer strip driving assembly 3 in fixing seat 1, the upper cover plate 4 for being mounted on 1 open end of fixing seat and peace
Blade 5, lower blade 6 and transfer strip 7 in fixing seat 1.Fixing seat 1 is equipped with installation blade driving assembly and transfer strip
The blade driving assembly installation position opening direction and fixing seat 1 of blade driving assembly are installed in the motor installation position of driving assembly 3
Open end is consistent, and blade driving assembly in open end from being installed in blade driving assembly installation position；Transfer strip driving group is installed
The transfer strip driving assembly installation position opening direction of part and the open end of fixing seat 1 are on the contrary, transfer strip driving assembly 3 is pacified from rear
It is attached in the transfer strip driving assembly of fixing seat 1.The motor rocking handle 31 of driving transfer strip 7, electricity are equipped in transfer strip driving assembly 3
Machine rocking handle 31 passes through fixing seat 1 from rear and extends to open end side, is connected by transfer strip actuating arm 8 and transfer strip 7.Switching
Piece actuating arm 8 includes turning end 81 and fixing end 82, and turning end 81 is the free end connecting with transfer strip 7, the end of turning end 81
Portion is equipped with actuating arm rocking handle 811, and actuating arm rocking handle 811 is inserted into the through-hole of transfer strip 7, when transfer strip actuating arm 8 is swung
When, actuating arm rocking handle 811 drags transfer strip 7.Fixing end 82 is rotatably fixed in fixing seat 1, is integrally formed in fixing seat 1
There is the rotation axis of installation fixing end 82, there is the through-hole of inserting rotation axis in fixing end 82.Rocking handle hole is additionally provided in fixing end 82
821, it is arranged in beside the through-hole of inserting rotation axis, motor rocking handle 31 is inserted into rocking handle hole 821 after passing through fixing seat 1.Rocking handle
Width a of the hole 821 on 31 swaying direction of motor rocking handle is greater than the width b of motor rocking handle, so that motor rocking handle 31 and rocking handle hole
There are starting gaps on swaying direction for 821 hole wall.When 3 driving motor rocking handle 31 of transfer strip driving assembly is swung, motor
Rocking handle 31 first swings a small distance, has obtained certain acceleration and then has contacted with the hole wall in rocking handle hole 821, such energy
It is enough smoothly transfer strip actuating arm 8 to be pushed to swing.
In order to enable motor rocking handle 31 obtains enough acceleration, rocking handle hole before contacting with the hole wall in rocking handle hole 821
The ratio of the width b of 821 width a and motor rocking handle 31 meets 1:2 <b:a < 3:4.In the present embodiment, rocking handle hole 821 is in side
Shape, the ratio of the width b of the width a and motor rocking handle 31 in rocking handle hole 821 are b:a=7:12.
In the present embodiment, in order to not influence other parts, transfer strip actuating arm 8 is arranged in close to 4 medial surface of upper cover plate
Position.When transfer strip actuating arm 8 is swung, the upper surface of transfer strip actuating arm 8 is easy to rub with the medial surface of upper cover plate 4
It wipes, so that motor rocking handle 31 drives transfer strip actuating arm 8 when swinging by very big resistance.It rubs to reduce, reduces resistance,
Actuating arm convex ribs 83 are equipped in the middle part of transfer strip actuating arm 8, the setting of actuating arm convex ribs 83 is in transfer strip actuating arm 8 towards upper cover plate 4
On the upper surface of side.
In the present embodiment, in order to avoid transfer strip actuating arm 8 and the blade 5 being arranged in below transfer strip 7 and driving
The rocking handle of blade 5 influences each other, and the middle part of transfer strip actuating arm 8 is equipped with clearance position 84, and the setting of clearance position 84 is driven in transfer strip
Swing arm 8 is towards the side of blade driving assembly 2.
In the present embodiment, the actuating arm rocking handle 811 in 8 turning end 81 of transfer strip actuating arm is inserted into the through-hole of transfer strip 7
Middle dragging transfer strip 7 moves, since iris ring device internal structure is compact, the limited length of actuating arm rocking handle 811, and In
Swing process is easy to deviate from from the through-hole of transfer strip 7, influences the use of iris ring device, therefore, actuating arm rocking handle 811
End is equipped with limited block 8111, and limited block 8111 is prominent to two sides along 811 swaying direction of actuating arm rocking handle, so that actuating arm
Rocking handle 811 is in T-shape, during transfer strip actuating arm 8 is swung, can catch on transfer strip 7, prevent actuating arm rocking handle 811
Deviate from from the through-hole of transfer strip 7.
In order to adapt to camera different imaging demand under various circumstances, more than one light hole is set on transfer strip 7,
It is corresponding on light hole to be equipped with filter disc.Light hole there are two being set on the transfer strip 7 of the present embodiment, it is corresponding to be provided with two panels difference
Filter disc.
When 3 driving motor rocking handle 31 of transfer strip driving assembly is rotated to side, motor rocking handle 31 is rotated through between starting
After gap, is contacted with hole wall of the rocking handle hole 821 of transfer strip actuating arm 8 in front of rotation direction, obtained certain acceleration, it is suitable
Smooth driving transfer strip actuating arm 8 is swung, and driving transfer strip actuating arm 8 drives transfer strip 7 to move to predetermined position, motor rocking handle
31 stop operating, and maintain the state contacted with the hole wall in rocking handle hole 821.When 3 driving motor rocking handle 31 of transfer strip driving assembly
When rotating to the other side, motor rocking handle 31 is just being attached to and the hole wall on the hole wall of this rotation direction opposite side, with the other side
There is a starting gap again, motor rocking handle 31 is contacted with the hole wall in front of rotation direction after starting gap, obtained again
Enough acceleration smoothly push transfer strip actuating arm 8 to swing.
The iris ring device of the double drive of the utility model, transfer strip driving assembly are equipped with unilateral motor rocking handle,
Motor rocking handle is inserted on transfer strip actuating arm, drives transfer strip to move back and forth in fixing seat by transfer strip actuating arm.It cuts
The rocking handle hole that piece actuating arm is equipped with inserting motor rocking handle is changed, the width in rocking handle hole and the width of motor rocking handle meet certain
Ratio, so that motor rocking handle is inserted into Shi Huiyu hole wall in rocking handle hole, there are certain gaps, drive when motor rocking handle is switched piece
When dynamic Component driver starts turning, there can be certain starting distance between motor rocking handle and rocking handle hole hole wall.When motor rocking handle
When contacting driving transfer strip driving arm swing with the hole wall in rocking handle hole, acceleration is had already passed through, driving force gets a promotion, and has enough
Dynamics drives transfer strip actuating arm that transfer strip is driven to move back and forth, and avoids insufficient and stuck in handoff procedure driving force.This is practical
The iris ring apparatus structure of novel double drive is simple, easy to process, it is not necessary that the internal structure of iris ring device is transformed
It can make moving back and forth in fixing seat to enough power for transfer strip, reliably replace different filter discs rapidly, adapt to
Camera different imaging demand under various circumstances.
