Description

Technical Field

[0001] This utility model relates to the field of auxiliary light source technology for macro cameras, specifically a positioning bracket for an auxiliary light source for macro camera autofocus. Background Technology

[0002] Macro cameras are photographic devices specifically designed for capturing tiny objects or details. Their core features are high magnification and short focusing distance. Through special optical designs or accessories (such as macro lenses, teleconverters, and bellows), these cameras can clearly capture details of tiny subjects like insects, flowers, and jewelry at close range, while simultaneously blurring the background with a large aperture to highlight the subject. An autofocus auxiliary light source for macro cameras is a device used to help macro cameras achieve fast and accurate autofocus in low-light or low-detail scenarios. In macro photography, due to the very close shooting distance and shallow depth of field, the camera's autofocus system may not function properly when ambient light is insufficient or the subject's surface texture is sparse. An auxiliary light source provides sufficient light, enhances image contrast, and helps the focusing system identify the object, thus improving the focusing speed and accuracy of macro cameras in low-light environments. When using auxiliary light sources, a positioning bracket is typically used to fix and support them in order to improve focusing accuracy and optimize lighting effects. An auxiliary light source positioning bracket is a mechanical device used to fix and adjust the position of the autofocus auxiliary light source so that it is precisely aligned with the subject. Fixing the light source position with a bracket ensures consistent lighting conditions for each shot, which helps improve image quality and also facilitates repeated shooting.

[0003] When using a positioning bracket, after the auxiliary light source is installed on the positioning bracket, the position of the auxiliary light source often needs to be adjusted according to the lighting and shooting requirements. In the existing technology, the height and horizontal position of the auxiliary light source are usually adjusted by fixing it with bolts. However, the bolt fixing method requires tightening multiple bolts one by one, which makes the operation inconvenient and the adjustment efficiency low. Therefore, in order to solve the above problems, a positioning bracket for an auxiliary light source for macro camera autofocus is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a macro camera autofocus auxiliary light source positioning bracket to solve the problem mentioned in the background art that the bolt fixing method requires tightening multiple bolts one by one during operation, which makes the operation inconvenient and the adjustment efficiency low.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a macro camera autofocus auxiliary light source positioning bracket, including a base, a support rod fixedly connected to the upper surface of the base, a connecting block movably connected to the surface of the support rod, a connecting plate fixedly connected to the surface of the connecting block, and an installation rod provided on the surface of the connecting plate;

[0007] The adjusting mechanism includes a threaded rod that is movable inside the support rod, and a positive and negative screw is movably connected to the inner side of the connecting plate. A second moving block is threadedly connected to the surface of the positive and negative screw.

[0008] The rotating mechanism includes a rotating rod, which is fixedly connected to a mounting rod, and a gear is fixedly connected to the surface of the rotating rod.

[0009] Preferably, the adjustment mechanism further includes a first movable block, which is threadedly connected to the surface of the threaded rod and is movable inside the support rod. A first fixed block is fixedly connected to the surface of the first movable block.

[0010] Preferably, the support rod has a limiting groove on its inner side, the first fixing block is fixedly connected to the first moving block in two sets, the limiting groove is fixedly opened in two sets on the inner side of the support rod, and the first fixing block moves within the limiting groove. The end of the first fixing block away from the first moving block is fixedly connected to the connecting block.

[0011] Preferably, the connecting plate has a movable groove on its inner side, and the positive and negative screws move within the movable groove, while the second moving block moves within the movable groove.

[0012] Preferably, the rotating mechanism further includes a second fixed block, which is fixedly connected to the surface of the second movable block, and the rotating rod is movable inside the second movable block. A movable rod is movably connected to the inner side of the second fixed block.

[0013] Preferably, a third fixing block is fixedly connected to the surface of the movable rod, and a spring is fixedly connected to the inner surface of the third fixing block.

[0014] Preferably, one end of the spring is fixedly connected to the second fixing block, and the other end of the spring is fixedly connected to the third fixing block.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By rotating the threaded rod, the first moving block can move vertically inside the support rod, and the first fixed block can drive the connecting block to move vertically accordingly. This allows the height of the mounting rod to be adjusted, so that the auxiliary light source can illuminate at different heights. At the same time, by rotating the positive and negative screws, the second moving block can move the mounting rod, allowing the auxiliary light source to illuminate at different horizontal positions. This makes the adjustment of the auxiliary light source more flexible and convenient, enabling the macro camera to autofocus faster and more accurately with the help of the auxiliary light source.

[0017] 2. The rotating rod allows the mounting rod to move. The movement of the rotating rod within the second fixed block, combined with the elasticity of the spring, enables the gear to be limited and released. This facilitates the rotation and fixing of the rotating rod and the mounting rod, allowing for flexible adjustment of the mounting rod's angle according to shooting needs. This allows the auxiliary light source to provide auxiliary light at different angles, improving the focusing accuracy of the macro camera. Attached Figure Description

[0024] 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.

[0025] Please see Figure 1-5 One embodiment provided by this utility model:

[0026] A positioning bracket for an auxiliary light source for autofocusing macro cameras includes a base 1. A support rod 11 is fixedly connected to the upper surface of the base 1. A connecting block 12 is movably connected to the surface of the support rod 11, and a connecting plate 13 is fixedly connected to the surface of the connecting block 12. A mounting rod 14 is provided on the surface of the connecting plate 13. An adjustment mechanism is provided on the inner side of the base 1, and a rotation mechanism is provided on the surface of the mounting rod 14. The adjustment mechanism includes a threaded rod 2, which is movably located inside the support rod 11. A positive and negative screw 25 is movably connected to the inner side of the connecting plate 13, and a second moving block 26 is threadedly connected to the surface of the positive and negative screw 25. The rotation mechanism includes a rotating rod 3, which is fixedly connected to the mounting rod 14, and a gear 31 is fixedly connected to the surface of the rotating rod 3. The support rod 11 and the connecting plate 13 can support the mounting rod 14. The mounting rod 14 facilitates the installation and fixation of the auxiliary light source, thereby facilitating the supplementary lighting for macro camera shooting and improving macro camera focusing.

[0027] Furthermore, the adjustment mechanism also includes a first movable block 21, which is threadedly connected to the surface of the threaded rod 2 and is movable inside the support rod 11. A first fixed block 22 is fixedly connected to the surface of the first movable block 21. By setting the threaded rod 2, the threaded rod 2 rotates, and the first movable block 21 can drive the first fixed block 22 to move vertically, thereby facilitating the adjustment of the position of the connecting block 12 on the support rod 11. This allows for flexible adjustment of the height of the mounting rod 14, enabling the position of the auxiliary light source to be flexibly adjusted according to the shooting requirements during shooting, which is beneficial to improving the accuracy and quality of macro camera focusing.

[0028] Furthermore, a limiting groove 23 is provided on the inner side of the support rod 11. The first fixed block 22 is fixedly connected to the first moving block 21 in two sets. The limiting groove 23 is provided in two sets on the inner side of the support rod 11, and the first fixed block 22 moves within the limiting groove 23. The end of the first fixed block 22 away from the first moving block 21 is fixedly connected to the connecting block 12. By setting the first fixed block 22 and opening the limiting groove 23, the first moving block 21 can be limited, which can prevent the first moving block 21 from shifting under the action of the threaded rod 2. This facilitates the first moving block 21 to drive the connecting block 12 to move vertically on the surface of the support rod 11 stably, thereby enabling the adjustment of the height of the auxiliary light source.

[0029] Furthermore, the inner side of the connecting plate 13 is provided with a movable groove 24, and the positive and negative screws 25 move within the movable groove 24. The second moving block 26 moves within the movable groove 24. By setting the second moving block 26, the positive and negative screws 25 rotate, and the second moving block 26 can drive the mounting rod 14 to move, thereby facilitating the adjustment of the spacing of the mounting rod 14 and adjusting the horizontal position of the auxiliary light source, making the use of the auxiliary light source more flexible and convenient.

[0030] Furthermore, the rotating mechanism also includes a second fixed block 32, which is fixedly connected to the surface of the second moving block 26. The rotating rod 3 moves inside the second moving block 26. The inner side of the second fixed block 32 is movably connected to a movable rod 33. Through the movement of the movable rod 33, it can engage and disengage with the teeth on the gear 31, thereby limiting and releasing the mounting rod 14. This allows for flexible adjustment of the illumination angle of the auxiliary light source, which is more convenient for providing auxiliary light source for macro camera shooting.

[0031] Furthermore, a third fixing block 34 is fixedly connected to the surface of the movable rod 33, and a spring 35 is fixedly connected to the inner surface of the third fixing block 34. By pulling the third fixing block 34, the movable rod 33 can be moved and the limit on the gear 31 can be released, so that the mounting rod 14 can move through the rotating rod 3, which facilitates the adjustment of the mounting rod 14.

[0032] Furthermore, one end of the spring 35 is fixedly connected to the second fixing block 32, and the other end of the spring 35 is fixedly connected to the third fixing block 34. By setting the spring 35, the third fixing block 34 can be reset, which in turn enables the movable rod 33 to be reset, making it easy for the movable rod 33 to be reset and engaged in the middle of the teeth of the gear 31, so that the gear 31 cannot rotate, thereby fixing the angle of the mounting rod 14 and ensuring the stability of the lighting.

[0033] Working principle: In use, rotating the threaded rod 2 causes the first moving block 21 to be limited by the first fixed block 22 and the limiting groove 23, and it will move vertically inside the support rod 11. This allows the first fixed block 22 to move inside the limiting groove 23, and the connecting block 12 to move on the surface of the support rod 11 under the action of the first fixed block 22, which can change the height of the mounting rod 14, thereby adjusting the height of the auxiliary light source. By rotating the positive and negative screws 25, the second moving block 26 is limited by the movable groove 24 and will move inside the movable groove 24 under the action of the positive and negative screws 25, thereby moving the mounting rod 14 and adjusting the horizontal position of the auxiliary light source.

[0034] By pulling the third fixing block 34, the movable rod 33 can move inside the second fixing block 32 and disengage from the teeth of the gear 31. At this time, the spring 35 is in a stretched state, thereby releasing the limit on the gear 31 and the rotating rod 3. Then, the mounting rod 14 is moved so that it can move through the rotating rod 3, allowing the angle of the mounting rod 14 to be adjusted. After adjustment, the third fixing block 34 is released, and the third fixing block 34 will reset under the rebound of the spring 35, thereby allowing the movable rod 33 to be inserted into the middle of the teeth of the gear 31, thus limiting the gear 31 and fixing the angle of the mounting rod 14, which can fix the auxiliary light source at the required angle.

[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
