[0032] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0033] Example:

[0034] like Figures 1-3 As shown, an in-lens shutter aperture assembly includes:

[0035] The fixed cover 1 has a threaded mounting hole inside and a groove on the edge, and a fixed positioning rod on one side;

[0036] The manual aperture adjustment assembly 2 is bolted to the side of the fixed cover 1 away from the fixed positioning rod;

[0037] The shutter adjustment assembly 3 is bolted to the side of the fixed cover 1 away from the manual aperture adjustment assembly 2, and is fitted onto the outer surface of the fixed positioning rod.

[0038] The shutter drive assembly 4 is fixedly mounted on one side edge of the shutter adjustment assembly 3;

[0039] The drive mechanism 5 is bolted inside the shutter drive assembly 4;

[0040] The FPC flexible circuit board 6 is soldered onto the surface of the drive mechanism 5.

[0041] The working principle of the above technical solution is as follows:

[0042] During use, the FPC flexible circuit board 6 provides power support to the drive mechanism 5, which in turn generates magnetic force on the shutter drive assembly 4, causing the internal components of the shutter drive assembly 4 to swing. This allows for the driving and adjustment of the internal components of the shutter adjustment assembly 3, as well as the manual deflection adjustment of the manual aperture adjustment assembly 2. The structure is simple and the operation is convenient and quick.

[0043] In another embodiment, such as Figure 2 As shown, the manual aperture adjustment assembly 2 includes a turntable 21. A manual lever 22 is fixedly provided on the edge of the turntable 21. Fixed guide grooves 24 are equidistantly provided on the inner edge of the turntable 21. An upper cover 23 is provided on the side of the turntable 21 away from the fixed cover 1. The upper cover 23 is connected to the fixed cover 1 by bolts. A fixed end rod 26 is movably provided on the inner side of the fixed guide groove 24. An aperture blade 25 is fixedly connected to one end of the fixed end rod 26. The aperture blade 25 is located between the fixed cover 1 and the turntable 21.

[0044] The manual lever 22 is easy to deflect, which drives the turntable 21 to deflect and cooperate with the fixed cover 1, so that the fixed end rod 26 can move inside the fixed guide groove 24, causing the aperture blade 25 to deflect, thereby opening and closing the aperture. The operation is convenient.

[0045] In another embodiment, such as Figure 2 As shown, the shutter adjustment assembly 3 includes an upper partition 31, which is sleeved on the outer side of the fixed positioning rod on one side of the fixed cover 1. An upper blade 33 is movably provided on one side of the upper partition 31, a lower partition 32 is provided on one side of the upper blade 33, and a lower blade 34 is provided on one side of the lower partition 32. An arc-shaped groove is provided at one end of the upper blade 33 and the lower blade 34 and at one end of the lower partition 32. A fixing seat 35 is provided on the side of the upper partition 31 away from the fixed cover 1 by bolts. The lower partition 32, the upper blade 33 and the lower blade 34 are located between the upper partition 31 and the fixing seat 35.

[0046] This allows the drive mechanism 5 to drive the shutter drive assembly 4, enabling the shutter drive assembly 4 to adjust the upper blade 33 and the lower blade 34, making it convenient and quick to use.

[0047] In another embodiment, such as Figure 2As shown, the shutter drive assembly 4 includes a fixed mounting block 41, a U-shaped iron 42 fixedly mounted on the inner side of the fixed mounting block 41, a fixed rod 43 fixedly mounted on the inner side of the fixed mounting block 41, a movable sleeve 44 movably sleeved on the outer surface of the fixed rod 43, a crank handle 45 fixedly connected to one end of the movable sleeve 44, a rocker arm 46 fixedly connected to the bottom end of the crank handle 45, a magnet 47 snapped onto the outer surface of the movable sleeve 44, one end of the rocker arm 46 is inserted into the interior of the fixed seat 35 and connected between the lower partition 32, the upper blade 33 and the lower blade 34, and the magnet 47 is located inside the end of the U-shaped iron 42.

[0048] The drive mechanism 5 can generate magnetic force on the U-iron 42, so that the end of the U-iron 42 can drive the magnet 47, which in turn drives the movable sleeve 44, the crank handle 45 and the rocker arm 46 to deflect and adjust. The rocker arm 46 drives the upper blade 33 and the lower blade 34, making operation convenient.

[0049] In another embodiment, such as Figure 2 As shown, the drive mechanism 5 includes a connecting cover plate 51. A through groove is provided on the surface of the connecting cover plate 51. A connecting mounting bracket 52 is provided inside the connecting cover plate 51. A winding shaft 54 ​​is provided on the inner side of the connecting mounting bracket 52. A terminal block 53 is provided on the outer side of the connecting mounting bracket 52. A coil 55 is provided on the outer side of the surface of the winding shaft 54. The coil 55 and the U-shaped iron 42 are in contact with each other. The connecting cover plate 51 and the fixed mounting block 41 are connected by bolts.

[0050] The FPC flexible circuit board 6 is convenient for supplying power to the terminals 53, so that the power is supplied to the coil 55. When the current flows inside the coil 55, it generates a magnetic force on the U-shaped iron 42, which is easy to operate.

[0051] In another embodiment, such as Figure 2 As shown, the wiring terminal 53 is located inside the through groove on the surface of the connecting cover plate 51.

[0052] This ensures that the wiring terminal 53 can be stably positioned inside the connecting cover 51, making operation convenient.

[0053] In another embodiment, such as Figure 2 As shown, the terminals of the FPC flexible circuit board 6 and the ends of the terminal blocks 53 are connected by soldering.

[0054] This facilitates stable power transmission through the FPC flexible circuit board 6 to the terminals 53 and the inside of the coil 55, making operation convenient.

[0055] The working principle of this utility model is as follows: During use, the FPC flexible circuit board 6 can transmit current to the inside of the coil 55 through the terminal 53, causing the U-iron 42 to generate magnetic force, which causes the magnet 47 to deflect on the outer side of the fixed rod 43, driving the rocker handle 45 and rocker arm 46 to deflect, thereby enabling the upper blade 33 and lower blade 34 to deflect and open / close. At the same time, it can also deflect the manual lever 22, driving the turntable 21 to deflect, which cooperates with the fixed cover 1, allowing the fixed end rod 26 to move inside the fixed guide groove 24, causing the aperture blade 25 to deflect, thereby performing the opening and closing process. The overall structure is simple and the operation is convenient and quick. When the whole assembly is installed at the camera lens, it can improve the overall user experience of the film camera and make operation convenient.

[0056] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
