If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] Understandably, referring to Figures 1 to 6 The filter quick-release mechanism of the first aspect of this utility model includes an adapter ring 100 and a support assembly 200. The adapter ring 100 is provided with a connecting part 110 and a first hook 120. The connecting part 110 is threadedly connected to a photographic device, and the first hook 120 is arranged around the connecting part 110. The support assembly 200 includes a support frame 210 and a pressure ring 220. The pressure ring 220 is threadedly connected to the support frame 210. The support frame 210 and the pressure ring 220 form a mounting groove 230 for accommodating a filter 300. The support frame 210 is slidably connected to a slider 240 in the radial direction. The slider 240 is provided with a second hook 241. An elastic element (not shown in the figure) is provided between the support frame 210 and the slider 240. The elastic element is used to drive the slider 240 to move away from the support frame 210 so that the first hook 120 can engage with the second hook 241.

[0034] The adapter ring 100 is provided with a connecting part 110 and a first hook 120. The connecting part 110 is threaded to the photographic equipment so that the adapter ring 100 can be fixed on the photographic equipment. The pressure ring 220 is threaded to the support frame 210. The support frame 210 and the pressure ring 220 form a mounting groove 230. The filter 300 is arranged in the mounting groove 230 so that the filter 300 can be stably placed between the support frame 210 and the pressure ring 220. The slider 240 is radially slidably connected to the support frame 210. The slider 240 is provided with a second hook 241. An elastic element is arranged between the support frame 210 and the slider 240. The support frame 210 is arranged on the adapter ring 100 so that the elastic element drives the slider 240 to move away from the support frame 210, so that the first hook 120 can engage with the second hook 241. This allows the adapter ring 100 and the support frame 210 to be quickly connected together, instead of being connected by threads. This improves the installation speed of the filter 300 and enhances the user experience.

[0035] The adapter ring 100 is fixedly connected to the photographic equipment via the connecting part 110. By pressing the slider 240, the slider 240 can compress the elastic element, allowing the second hook 241 to retract. Then, the support frame 210 is placed on the adapter ring 100, and the second hook 241 passes over the first hook 120. Then, the slider 240 is released, causing the elastic element to drive the slider 240 to reset, allowing the slider 240 to move away from the support frame 210. This allows the first hook 120 and the second hook 241 to engage together, improving the installation speed of the filter 300 and replacing the threaded rotation connection, thus improving the user experience.

[0036] In addition, the first hook 120 is arranged around the connecting part 110 so that when the first hook 120 is engaged with the second hook 241, the second hook 241 can slide on the first hook 120, thereby making it easy to adjust the angle of the filter 300 and adapt to the usage requirements of the filter 300.

[0037] It should be noted that the filter 300 can be a star filter, a brushed filter, etc., so that after the filter 300 is fixed in the mounting slot 230, it can rotate on the adapter ring 100 through the drive support 210, thereby adapting to the usage requirements of the filter 300.

[0038] Elastic components can be springs, rubber parts, silicone parts, or other elastic elements, which will not be elaborated on here.

[0039] Understandably, referring to Figure 4 and Figure 6The support frame 210 is provided with a connecting ear 211, and two limiting blocks 212 are fixedly connected to the connecting ear 211. The two limiting blocks 212 are respectively arranged on both sides of the connecting ear 211. The limiting blocks 212 have limiting grooves 213. The slider 240 has limiting parts 242 on both sides, and the limiting parts 242 are located in the limiting grooves 213. By setting the limiting parts 242 in the limiting grooves 213, the sliding range of the slider 240 can be limited, preventing the slider 240 from moving excessively under the drive of the elastic element and detaching from the support frame 210. This improves the stability of the connection between the slider 240 and the support frame 210, and allows the second hook 241 to accurately and reliably engage with the first hook 120, thereby improving the overall stability of the filter quick-release mechanism.

[0040] In addition, the cooperation between the limiting groove 213 and the limiting part 242 can improve the positional accuracy of the slider 240, avoid the problem of poor or no engagement caused by positional deviation, and further improve the stability and reliability of the filter 300 installation.

[0041] Specifically, refer to Figure 4 and Figure 5 The limiting block 212 is fitted with a fastener (not shown in the attached drawing), and the fastener is threadedly connected to the connecting ear 211. The fastener can fix the limiting block 212 to the connecting ear 211, which allows for easy installation and removal of the limiting block 212. When maintenance or replacement of the limiting block 212 is required, the fastener can be rotated to achieve disassembly and assembly, improving the convenience of operation.

[0042] It should be noted that fasteners can be bolts, screws, bolts, etc., which will not be listed in detail here.

[0043] Specifically, refer to Figures 3 to 6 The connecting ear 211 has a guide groove 214, and the slider 240 has a guide part 243. The guide part 243 is slidably connected in the guide groove 214, and the width of the guide groove 214 matches the width of the guide part 243. The guide part 243 is slidably connected in the guide groove 214 so that the guide part 243 can slide smoothly along the length direction of the guide groove 214. By setting the width of the guide groove 214 to match the width of the guide part 243, the slider 240 can always maintain a stable movement trajectory when sliding radially, avoiding the slider 240 from deviating or shaking during the sliding process, thereby improving the accuracy and reliability of the engagement between the second hook 241 and the first hook 120.

[0044] In addition, by matching the widths of the guide groove 214 and the guide part 243, it is possible to prevent the guide part 243 from becoming loose or stuck in the guide groove 214, so that the installation and removal process of the filter 300 is smooth and stable, thereby improving the efficiency of the installation and removal of the filter 300 and enhancing the user experience.

[0045] Specifically, refer to Figures 4 to 6 The elastic element is arranged in the guide groove 214, with one end abutting against the guide portion 243 and the other end abutting against the bottom wall of the guide groove 214. By arranging the elastic element in the guide groove 214, the position of the elastic element is defined and stabilized, thereby enabling the elastic element to stably push the slider 240 to slide, reducing the positional offset of the slider 240, and making the overall structure more compact, reducing the size, and improving the ease of use.

[0046] One end of the elastic element abuts against the guide portion 243, and the other end abuts against the bottom wall of the guide groove 214, providing stable support for the elastic element, improving the stability of the elastic force during long-term use, avoiding the problem of insufficient elastic force caused by deformation or displacement of the elastic element, and thus improving the durability and reliability of the filter quick-release mechanism.

[0047] Specifically, refer to Figures 3 to 6 The guide grooves 214 and guide parts 243 are both multiple, with the multiple guide grooves 214 arranged in parallel at intervals, and each guide groove 214 corresponds to a guide part 243. The cooperation of multiple guide grooves 214 and multiple guide parts 243 can provide more stable and precise guidance for the sliding of slider 240, and can also distribute the force on slider 240 during sliding, reduce the phenomenon of slider 240 jamming or deviating due to excessive local force, enhance load-bearing capacity, extend service life, and enable slider 240 to slide more smoothly and steadily, thereby improving the durability of the filter quick-release mechanism.

[0048] In addition, the parallel and spaced guide grooves 214 further enhance the accuracy of guidance, improve the straightness and stability of the slider 240 during sliding, thereby improving the accuracy and reliability of the engagement between the second hook 241 and the first hook 120.

[0049] Understandably, referring to Figures 2 to 4 The number of sliders 240 is set to two, and the two sliders 240 are arranged opposite each other on the support frame 210. The two opposing sliders 240 can work together to install and fix the filter 300, and can more evenly distribute the pressure and stress generated by the support frame 210 on the adapter ring 100, so that the support frame 210 can be stabilized on the adapter ring 100 and the positional wobbling of the support frame 210 can be reduced.

[0050] In addition, the two sliders 240 are arranged opposite each other. During installation, the user can press both sliders 240 at the same time, which makes it easier for the user to grip and apply force, making the installation of the support frame 210 more convenient and improving the user experience.

[0051] Understandably, referring to Figure 4 and Figure 6 A handle 244 is provided at the end of the slider 240 away from the first latch 120, and the handle 244 extends axially along the support frame 210. The handle 244, located at the end of the slider 240 away from the first latch, provides a more convenient and effortless position for the user to press the slider 240. Furthermore, the axial extension of the handle 244 along the support frame 210 increases its surface area, helping the user quickly locate and operate the slider 240, and distributing pressure on the hand, thus improving user comfort.

[0052] Understandably, referring to Figures 1 to 3 Multiple support components 200 are provided. A third hook 215 is provided at the end of the support frame 210 furthest from the adapter ring 100. The third hook 215 is arranged circumferentially along the support frame 210. Adjacent support frames 210 are engaged via a second hook 241 and a third hook 215. The multiple support components 200 allow for the simultaneous mounting of multiple filters 300, meeting the user's needs for combining various filters 300 in different shooting scenarios, thus improving shooting flexibility and versatility. The engagement of adjacent support frames 210 via the second hook 241 and the third hook 215 ensures a stable connection between the multiple support components 200, facilitating adjustments to the layout and number of filters 300, and improving operational convenience and efficiency.

[0053] It should be noted that multiple support components 200 are provided to facilitate the combined installation of multiple filters 300. A third hook 215 is provided at the end of the support frame 210 furthest from the adapter ring 100. The second hook 241 of the preceding support component 200 can engage with the third hook 215 of the following support component 200, allowing multiple support components 200 to be quickly installed together. This facilitates the combined use of multiple filters 300 and improves the user experience.

[0054] In addition, the third hook 215 is arranged around the circumference of the support frame 210 so that two adjacent support components 200 can rotate relative to each other, making it convenient to adjust the angle of the filter 300 and improving the user experience.

[0055] It is understood that the photographic device of the second aspect embodiment of the present invention includes the filter quick-release mechanism of the first aspect embodiment of the present invention. Since it has all the technical features of the filter quick-release mechanism of the above embodiments, it also has the beneficial effects of all the above embodiments, which will not be repeated here.

[0056] It should be noted that, referring to Figure 1 and Figure 3 The photographic equipment includes cameras, video cameras, etc., and cameras and video cameras are equipped with lenses. The adapter ring 100 is threaded to the lens. The support frame 210 is fixedly connected to the adapter ring 100 through the first hook 120 and the second hook 241. The filter 300 is arranged between the support frame 210 and the pressure ring 220, which can simplify the installation method of the filter and improve the installation efficiency.

[0057] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
