[0002] In the field of photography, macro photography places high demands on aperture control. Existing macro photography devices have certain shortcomings in use. They cannot achieve low-profile installation well, and their aperture control is not flexible enough. They cannot quickly and accurately adjust to the appropriate aperture size according to different lighting conditions. In actual shooting, their adaptability to light is limited. When the light is sufficient or insufficient, they cannot easily switch to the appropriate aperture value, which affects the shooting effect. At the same time, the operation of existing devices during focusing is relatively complicated, and they cannot quickly and accurately find the focus point, which affects shooting efficiency.

[0003] This solution provides a variable aperture control device for macro photography, aiming to solve the aforementioned problems in the prior art. This device can adjust the aperture size between f8 and f5.6 according to lighting conditions; f8 is selected in sufficient light, and f5.6 in poor light. Operation is convenient and quick. Through a special adjustment mechanism, the movement positions of the two limit levers can be flexibly adjusted, thereby achieving precise aperture control. During focusing, the focus point can be quickly found through the focus lamp and adjustable slider, improving shooting efficiency. Furthermore, the device is reasonably designed and can be installed in a low position to meet the needs of different shooting scenarios. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figures 1-4 The present invention provides the following technical solution:

[0031] A variable aperture control device for macro photography, comprising:

[0032] Shooting sleeve 1, with fixing plates 16 fixedly connected to the inner walls of both sides of shooting sleeve 1, and a glass plate 12 fixedly connected inside the fixing plate 16;

[0033] Camera 5 is set inside the shooting sleeve 1. A focusing lamp 6 is installed on the top of the camera 5, and a macro lamp 7 and a xenon lamp 8 are installed at both ends of the camera 5, respectively.

[0034] Limiting rod 2, there are two limiting rods 2, both of which are set inside the shooting sleeve 1;

[0035] Support sleeve 13, support sleeve 13 is fixedly connected to the lower inner wall of the shooting sleeve 1; and

[0036] An adjustment mechanism is located inside the shooting sleeve 1. The adjustment mechanism is used to adjust the moving position of the two limit rods 2.

[0037] In a specific embodiment of this utility model, 4. Camera 5: Currently, cameras suitable for macro photography include Nikon D850, Nikon Z6, Canon EOS R5, Canon 90D, Sony A7M4, M3, Fujifilm X-Pro3, and Olympus OM-D E-M10 Mark IV. As long as the camera has 15 megapixels and is equipped with a macro lens, it can shoot macro effects. However, to achieve better shooting effects, a more powerful CMOS and higher pixel count are required.

[0038] 5. Macro Lens: After testing 5 macro lenses, we found that the Laowa 90mm f / 2.8 lens with 2x magnification is quite in line with the product positioning in terms of both image quality and price.

[0039] 6. The macro light 7 is a crucial step in the entire shooting process. After testing many macro lights 7, it was concluded that the macro light 7 must be comfortable for the customer (not too bright, as direct light to the eyes is glaring) while also ensuring good shooting results. Therefore, an imported Kuangren xenon macro light 7 was chosen, using a K808 battery with a hydrogen bromine battery. The adjustable focus lamp at the front facilitates camera focusing, while the left and right flashes capture iris details. The shooting sleeve 1 provides a protective housing for the entire macro photography variable aperture control device, ensuring stable installation and operation of all internal components. The fixing plates 16 fixed to the inner walls on both sides provide mounting positions for the glass plate 12. Simultaneously, the shooting sleeve 1 as a whole defines the working space of the device. In terms of spatial range, secondly, the glass plate 12 serves two purposes: firstly, it protects the internal components of the shooting sleeve 1, preventing external objects from directly contacting the precision components such as the camera 5; secondly, during shooting, the glass plate 12 allows light to pass through, ensuring that light can enter the shooting sleeve 1 normally and provide suitable lighting conditions for the camera 5. Thirdly, the camera 5, as the core component of the entire device, undertakes the main task of macro photography. Through its own optical system and image sensor, it converts the image of the subject into electronic signals, thereby realizing image recording and storage. The focusing lamp 6 installed on the top can provide auxiliary focusing function for the camera 5 during shooting, ensuring that the camera 5 can quickly and accurately focus on the subject. Macro lights 7 and xenon lights 8, installed at both ends of the object being photographed, provide additional illumination according to different shooting environments, improving the quality and effect of the shooting. A macro lens is installed at the front of the camera 5, which can capture high-definition images of the delicate texture of the iris. Fourth, the two limiting rods 2 provide certain structural support and limiting functions for the device. Under the action of the adjustment mechanism, the limiting rods 2 can limit the movement range of the camera 5 and other components, ensuring the stability and accuracy of the camera 5 during the shooting process. At the same time, the limiting rods 2 can also provide a basis for the installation and operation of the adjustment mechanism. Fifth, the support sleeve 13 is fixedly connected to the lower inner wall of the shooting sleeve 1, providing bottom support and stability for the entire device, ensuring that the device will not shake or wobble during placement and use. In a stable condition, ensuring the quality and effect of the shooting, the adjustment mechanism can adjust the position and shooting angle of the camera 5 by adjusting the movement position of the two limit rods 2. Specifically, the adjustment mechanism can adjust parameters such as the distance and angle between the camera 5 and the subject according to different shooting needs, thereby controlling the aperture and optimizing the shooting effect. At the same time, the precise adjustment function of the adjustment mechanism can improve the accuracy and repeatability of shooting, meeting the shooting needs of different users. It should be noted that the specific model of macro lamp 7, camera 5, and xenon lamp 8 used shall be selected by those skilled in the art, and the above-mentioned macro lamp 7, camera 5, xenon lamp 8, etc. are all existing technologies, which will not be elaborated in this solution.

[0040] Please refer to the details. Figures 1-4 The regulating mechanism includes:

[0041] Positioning sleeve 11, two positioning sleeves 11 are provided, and the two positioning sleeves 11 are respectively fixedly connected to the outer surface of the two limiting rods 2;

[0042] The limiting groove 14 is provided in two places, and the two limiting grooves 14 are respectively opened at the far ends of the two positioning sleeves 11.

[0043] Two threaded holes 15 are provided, and the two threaded holes 15 are respectively opened at the close ends of the two positioning sleeves 11.

[0044] Two screws 10 are provided, and the two screws 10 are respectively threaded into two threaded holes 15. The two screws 10 are respectively movably engaged in two limiting sleeves 9.

[0045] The sliding sleeve 4 is slidably connected to the outer surface of the two limiting rods 2. The top of the sliding sleeve 4 is fixedly connected to the slide rail 3, and the camera 5 is slidably connected inside the slide rail 3.

[0046] In this embodiment: 1. The positioning sleeve 11 is fixedly connected to the outer surface of the limiting rod 2, providing an interface for the limiting rod 2 to connect with other components. On the one hand, it makes the position of the limiting rod 2 in the device more stable, preventing unnecessary movement or shaking of the limiting rod 2 during operation. On the other hand, the positioning sleeve 11 provides an installation position for subsequent adjustment components such as screws 10, enabling the adjustment mechanism to effectively adjust the limiting rod 2. 2. The limiting groove 14, located at the far end of the positioning sleeve 11, can cooperate with other components to limit the movement range of the positioning sleeve 11. During adjustment, the limiting groove 14... 4. This prevents the positioning sleeve 11 from moving excessively, thus ensuring the stability and reliability of the entire adjustment mechanism. Simultaneously, the limiting groove 14 provides a guiding function for the adjustment mechanism, making the adjustment process more accurate and smooth. III. The threaded hole 15, located near the end of the positioning sleeve 11, provides a connection interface for the screw 10. Through threaded connection, the screw 10 can rotate within the threaded hole 15, thereby adjusting the position of the positioning sleeve 11. The threaded hole 15 ensures a certain degree of precision and repeatability in the adjustment process, allowing for precise adjustment of the positioning sleeve 11's position according to actual needs. IV. The screw 10... The threaded connection is inside the threaded hole 15 and is movably engaged in the limiting sleeve 9. By rotating the screw 10, the position of the positioning sleeve 11 on the limiting rod 2 can be changed. The adjustment function of the screw 10 can achieve precise control of the movement position of the limiting rod 2, thereby adjusting the shooting angle and position of the camera 5. At the same time, the movable engagement of the screw 10 in the limiting sleeve 9 can prevent the screw 10 from falling off during the adjustment process, ensuring the stability and reliability of the adjustment mechanism. Fifth, the sliding sleeve 4 is slidably connected to the outer surface of the two limiting rods 2, providing a platform for support and movement for the slide rail 3 and the camera 5. The sliding sleeve 4 can slide freely on the limiting rod 2, thereby driving the slide rail 3. The position of the camera 5 is adjusted by the sliding connection of the slide 4, which makes the position adjustment of the camera 5 more flexible and convenient. The position of the camera 5 can be quickly adjusted according to different shooting needs. The slide 3 is fixedly connected to the top of the slide 4, and the camera 5 is slidably connected inside the slide 3. The slide 3 provides a stable sliding track for the camera 5, allowing the camera 5 to be precisely adjusted on the slide 3. The setting of the slide 3 can ensure that the camera 5 remains stable during the position adjustment process, improving the shooting quality and effect. At the same time, the slide 3 can also provide a certain range of adjustment for the shooting angle of the camera 5 to meet different shooting needs.

[0047] The working principle and usage process of this utility model are as follows: 1. Preparation stage: Confirm that the lens aperture needs to be kept at f8-f5.6 at all times. Select according to the lighting conditions. Select f8 when the light is sufficient and f5.6 when the light is poor. Check the shooting sleeve 1. Ensure that the glass plate 12 inside the fixing plate 16 fixedly connected to the inner wall on both sides is intact, so as to provide protection for the internal components and a certain degree of light transmission.

[0048] II. Shooting Operation Stage: Turn on the power to camera 5. At this time, camera 5 is located inside shooting sleeve 1. The focus light 6 on its top, the macro lights 7 at both ends, and the xenon lights 8 are in standby mode. After turning on the macro light 7, push shooting sleeve 1 forward to the appropriate position. Instruct the customer to close their eyes first, then press the up button to turn on the focus light 6. Taking the customer's left eye as an example, unlock the horizontal slide rail 3. The slide rail 3 is slidably connected to the two limit rods 2 via the sliding sleeve 4. The sliding sleeve 4 can move freely on the limit rods 2, thereby moving the slide rail 3 and camera 5 to the appropriate position. Hold shooting sleeve 1 with your hand, your thumb... Place the camera on the shutter button of camera 5, quickly rotate the lens of camera 5 to focus on the iris of the eye according to the scene, and observe whether the light can clearly see the iris texture. If not, the focus light 6 in front needs to be adjusted. The position of focus light 6 can be adjusted by adjusting the position of camera 5 on slide rail 3 and rotating screw 10 to change the position of positioning sleeve 11 on limit rod 2, thereby adjusting the overall position of camera 5 and focus light 6. Instruct the person to open their eyes. If eyelashes are blocking the shooting scene, the customer needs to use their hands to open the upper and lower eyelids. The operator quickly finds the focus point and presses the shutter to complete the shooting task.

[0049] III. Inspection and Feedback Stage: Check whether the captured iris image is qualified. If it is qualified, it will be fed back to the external device for storage or modification in an electrical manner. The support sleeve 13 inside the shooting sleeve 1 provides bottom support for the entire device. The positioning sleeve 11 on the limiting rod 2, through the cooperation of the limiting groove 14, threaded hole 15 and screw 10 with the limiting sleeve 9, realizes the precise adjustment of the position of the camera 5 to ensure the shooting effect.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
