Onto integrally formed driving motor installation end cap 26, then mounted component is put on coil winding machine together, driving coil is installed
22, finally put on driving motor shell 21.
It avoids cover blade from directly hitting with shutter pedestal, reduces the active force that cover blade receives in shutter opening and closing,
The utility model is provided with buffering spacer mounting bracket 12 on shutter pedestal 1, is mounted with inside buffering spacer mounting bracket 12
Buffering spacer 11 made of padded coaming.Since shutter is opened the door and closed two kinds of door movements, anti-deformation is drivingly connected arm
32 will receive the impact force of different directions twice, therefore for opening the door and closing a situation, buffering spacer mounting bracket 12 is provided with
Two, a buffering spacer bracket respectively is closed for the enabling buffering spacer bracket 121 of door opening action and for close movement
122.Shutter pedestal 1 is arranged in close to the position of driving motor group 2, enabling buffering spacer bracket in enabling buffering spacer bracket 121
Enabling is installed in 121 and hits buffering spacer 111.A buffering spacer bracket 122 is closed to be arranged in shutter pedestal 1 far from driving motor
The position of group 2 is closed in a buffering spacer bracket 122 to be equipped with and closes a shock buffering spacer 112.With the shock on shutter pedestal 1
Buffer gear is corresponding, is drivingly connected arm 32 and is equipped with anticollision protrusion 323, anticollision protrusion 323 is set also for shutter door movement
It has set enabling anticollision protrusion 3232 and has closed an anticollision protrusion 3231.In the present embodiment, enabling anticollision protrusion 3232 with it is fast
Enabling buffering spacer bracket 121 on door pedestal 1 is corresponding, and setting is being drivingly connected arm 32 and 1 opposing side edges of shutter pedestal
On, it is one to 1 direction of shutter pedestal protrusion outstanding, close to the position of driving motor group 2；Close anticollision protrusion 3231 with
Buffering spacer bracket 122 is corresponding, and setting is on being drivingly connected 32 edge of arm, far from driving motor for closing on shutter pedestal 1
The position of group 2 is a protrusion being drivingly connected on 32 side of arm.Since shutter on-off action is very frequent, if shutter door
Movement uses same set of impact buffering mechanism, and buffer gear is easier to damage, and is drivingly connected arm 32 and is also easy due to long-term same
Some stress and deform, therefore the present embodiment for different movements be provided with corresponding buffer gear.In door opening action, open
Door anticollision protrusion 3232 is hit buffering spacer 111 with the enabling installed in enabling buffering spacer bracket 121 and is hit, and opens the door and hits
The effective buffering percussive force of buffering spacer 111 reduces the stress for being drivingly connected arm 32.In closing a movement, an anticollision protrusion is closed
3231 hit with closing closing of installing in a buffering spacer bracket 122 and hit a buffering spacer 112, close and hit a buffering spacer 112
Impact force has been buffered, stress of the arm 32 in movement has been drivingly connected and reduces.
When installation, first the Connection protrusion 242 on actuating arm 24 is inserted into the locking half bore 3212 of connecting hole 321, then will
Screw, which is installed in screw hole, is fixed together Connection protrusion 242 and connecting hole 321, actuating arm 24 and 3 energy of cover blade
It is securely attached to together, not need to be bonded using glue etc..
It is connected in use, being mounted on conducting wire and driving motor component 2 on shutter pedestal 1, driving motor component 2 is powered, forever
Magnet rotors part 23 starts turning under the magnetic fields of driving coil 22, and drive is mounted in actuating arm connection mounting hole 231
Actuating arm 24 rotate, limiting groove 232 blocks the arm body position of actuating arm 24, it is ensured that actuating arm 24 will not be beaten in rotation
It is sliding.Actuating arm 24 drives cover blade 3 to switch opening the door and close in door state, cuts for into the light of camera.Actuating arm 24
On Connection protrusion 242 it is tough enough, 24 top of arm will not be directly driven and open up screw hole, keep actuating arm 24 in use
The case where explosion, shutter action fails.
The seperated screw connection structure of the utility model is connected using screw, can be to avoid welding or dispensing fixed form meeting
There is the problem that falls off occurred due to ageing of plastics；Secondly, reducing the thickness of threaded connector simultaneously using split type screw thread
Increase the effective length being threadedly coupled；Simultaneously as screw thread is separately positioned on two connectors, do not need on two connectors
Screw hole is all opened up, when using on some tiny workpiece such as infrared shutter part, the damage of part connecting portion can be reduced
Probability.
