Description

Technical Field

[0001] This utility model belongs to the technical field of shooting equipment accessories, and in particular relates to a highly adaptable quick-release filter structure. Background Technology

[0002] Filters are tools used to filter natural light and can quickly change the way content is presented. In order to improve the artistry of shooting, people usually install filters with corresponding effects in front of the camera lens of the shooting equipment.

[0003] There are two main methods for installing filters. One is to glue the filter directly to the inside of the camera lens, which makes the filter impossible to remove and replace, causing the camera to lose its normal shooting effect and resulting in a poor user experience. The other method is to use a pre-cut slot on the camera lens shell to attach the filter. This requires the filter and camera lens to be the same size, which means that a filter of the same size cannot be used on cameras of different sizes and models, resulting in poor versatility. Therefore, it is necessary to design a highly adaptable quick-release filter structure to solve this problem. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] This invention provides a highly adaptable quick-installation filter structure, which not only facilitates the quick installation and removal of filters, but also allows filters to be adapted to various camera sizes.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A highly adaptable quick-release filter structure includes a lens mount and a fastening sleeve. A filter is mounted on the lens mount. The fastening sleeve is detachably mounted on the lens mount, and its interior has a cavity for mounting a camera, allowing the lens mount to be fixed to the camera via the fastening sleeve, thereby mounting the filter onto the camera. Multiple fastening sleeves are provided, each with a different inner diameter, enabling each sleeve to be adapted to various camera sizes. By replacing the appropriate fastening sleeve on the lens mount, the filter can be mounted onto cameras of various sizes.

[0009] Preferably, the lens mount has an internal mounting cavity with openings at the top and bottom, and the inner diameter of the mounting cavity is larger than the outer diameter of the camera; the fastening sleeve is slidably disposed in the mounting cavity and is interference-fitted with the mounting cavity, and the sleeve cavity of the fastening sleeve is interference-fitted with the camera; the filter is mounted on the top of the lens mount and covers the opening at the top of the mounting cavity, so that the camera faces the filter directly.

[0010] Preferably, the fastening sleeve is made of an elastic material.

[0011] Preferably, the fastening sleeve is made of silicone or rubber material.

[0012] Preferably, a circular limiting strip is provided at the lower opening of the cavity, and after the camera is fitted into the cavity, the limiting strip abuts against the bottom wall of the camera.

[0013] Preferably, the inner wall of the sleeve cavity has multiple anti-slip strips protruding from it, and the multiple anti-slip strips are arranged in an array along the axis of the sleeve cavity. After the camera is fitted into the sleeve cavity, the multiple anti-slip strips simultaneously abut against the outer wall of the camera.

[0014] Preferably, the top of the lens mount is provided with a hidden groove for mounting the filter. The hidden groove is connected to the opening above the mounting cavity, and the hidden groove, the mounting cavity, and the sleeve cavity are designed to be coaxially fixed above the camera.

[0015] Preferably, the fastening sleeve and the mounting cavity are fitted with a clearance fit. After the camera is fitted into the cavity, the fastening sleeve deforms, and the deformation of the fastening sleeve is greater than the clearance value between the fastening sleeve and the mounting cavity, so that the fastening sleeve abuts against the inner wall of the mounting cavity after deformation.

[0016] Preferably, the inner diameter of the sleeve cavity gradually decreases from bottom to top, so that during the process of the sleeve cavity fitting the camera, the camera squeezes the inner wall of the sleeve cavity, causing the fastening sleeve to gradually deform.

[0017] Preferably, the maximum inner diameter of the cavity is slightly larger than the outer diameter of the camera.

[0035] See appendix Figure 1 -Appendix Figure 6 A highly adaptable quick-release filter structure includes a lens mount 1 and a fastening sleeve 3. A filter 2 is mounted on the lens mount 1. The fastening sleeve 3 is detachably mounted on the lens mount 1, and the fastening sleeve 3 has a cavity 30 inside for mounting a camera 4, so that the lens mount 1 can be fixed to the camera 4 through the fastening sleeve 3, thereby mounting the filter 2 onto the camera 4. There are multiple fastening sleeves 3, and the inner diameter of the cavity 30 of the multiple fastening sleeves 3 is different, so that the multiple fastening sleeves 3 can be adapted to mount cameras 4 of various specifications.

[0036] Specifically, when installing filter 2, first select a fastening sleeve 3 with a corresponding cavity 30 according to the size specifications of the camera 4 on which filter 2 is to be installed. Then, install the fastening sleeve 3 onto the lens mount 1. Then, move the lens mount 1 to drive the cavity 30 onto the camera 4, so that the lens mount 1 and filter 2 can be installed on the camera 4 for use.

[0037] Similarly, when replacing the camera 4 with another type of camera and needing to install the filter 2 on the other type of camera 4, first remove the lens mount 1 and the fastening sleeve 3 from the camera 4 together, then remove the fastening sleeve 3 from the lens mount 1, then select a fastening sleeve 3 that is compatible with the new camera 4, and install the selected fastening sleeve 3 onto the lens mount 1. Finally, move the lens mount 1 to drive the cavity 30 of the fastening sleeve 3 to fit the camera 4.

[0038] In summary, this utility model designs a lens mount 1 for mounting the filter 2, and a fastening sleeve 3 on the lens mount 1 for mounting the camera 4, thereby installing the filter 2 onto the camera 4 and facilitating quick installation and removal of the filter 2. By designing multiple fastening sleeves 3 with different internal cavity specifications for connecting the lens mount 1 and the compatible camera 4 one by one, the filter 2 can be adapted to be installed on cameras 4 of various specifications (models). Therefore, the above structural design improves the adaptability of the filter 2, making it highly versatile, while also ensuring the overall user experience.

[0039] It should be noted that the camera 4 is an existing product, and its lens end is either fixed integrally with the camera 4 body or can be disassembled and replaced separately. Therefore, in the above content, the cavity 30 of the fastening sleeve 3 is used to fit the lens end of the camera 4, and the replacement of the camera 4 can refer to replacing the entire camera 4 or only replacing the lens end of the camera 4. These are determined according to the actual situation of the camera 4, and this utility model does not impose any restrictions on this.

[0040] See appendix Figure 1 -Appendix Figure 6 The lens mount 1 has an upper and lower opening mounting cavity 10 inside, and the inner diameter of the mounting cavity 10 is larger than the outer diameter of the camera 4; the fastening sleeve 3 is slidably set in the mounting cavity 10 and is interference-fitted with the mounting cavity 10, and the sleeve cavity 30 of the fastening sleeve 3 is interference-fitted with the camera 4; the filter 2 is installed on the top of the lens mount 1 and covers the upper opening of the mounting cavity 10 so that the camera 4 faces the filter 2 directly.

[0041] Specifically, the mounting cavity 10 is used to enclose the fastening sleeve 3 and the camera 4 to reduce the overall volume and improve aesthetics. The fastening sleeve 3 is interference-fitted with the mounting cavity 10, allowing the fastening sleeve 3 to be detachably mounted on the lens base 1, facilitating the assembly and disassembly of the lens base 1 and multiple fastening sleeves 3. The cavity 30 of the fastening sleeve 3 is interference-fitted with the camera 4, which allows the lens base 1 to be mounted more stably on the camera 4, preventing the filter 2 from detaching from the camera 4 due to shaking during use. On the other hand, the camera 4 faces the filter 2 directly, which can shorten the distance between the two and improve the accuracy of the filter 2.

[0042] It should be noted that, in addition to the above methods, other methods can be used to achieve the detachable connection between the fastening sleeve 3 and the lens base 1. For example, a buckle (not shown in the figure) can be designed on the lens base 1 to fasten the fastening sleeve 3, or a matting adhesive surface (not shown in the figure) and a rough surface (not shown in the figure) can be provided on the inner wall of the mounting cavity 10 and the outer wall of the fastening sleeve 3. Since there are many related methods, this utility model does not limit them.

[0043] See appendix Figure 3 -Appendix Figure 8 The fastening sleeve 3 can be made of hard material or elastic material. However, considering that the fastening sleeve 3 is in an interference fit with the mounting cavity 10 and the camera 4 is in an interference fit with the sleeve cavity 30, if the fastening sleeve 3 is made of hard material, the lens mount 1, the fastening sleeve 3 and the camera 4 will easily wear after long-term disassembly and assembly. Therefore, in this embodiment, the fastening sleeve 3 is made of elastic material.

[0044] Specifically, whether the fastening sleeve 3 is placed inside the mounting cavity 10 or the camera 4 is mounted using the sleeve cavity 30, the fastening sleeve 3 will undergo adaptive deformation to avoid rigid collision with the lens mount 1 and the camera 4, thus extending the service life of the relevant components.

[0045] See appendix Figure 5 -Appendix Figure 8 The fastening sleeve 3 is made of elastic material and has the ability to deform. Related elastic materials include silicone, rubber, TPE, etc. Since there are many types of elastic materials, this utility model does not limit them. In order to ensure wear resistance, the fastening sleeve 3 in this case is preferably made of silicone material. Silicone has good elasticity, can withstand large stretching and compression without being easily damaged, and silicone has strong wear resistance and a longer service life.

[0046] See appendix Figure 3 -Appendix Figure 9 To ensure that the fastening sleeve 3 can more stably mount the camera 4, the fastening sleeve 3 in this utility model shall have at least the following structures:

[0047] Firstly, as attached Figure 3 and attached Figure 8 As shown, the fastening sleeve 3 is made of elastic material, and a circular limiting strip 301 is provided at the lower opening of the sleeve cavity 30. The limiting strip 301 can abut against the bottom wall of the camera 4. Specifically, during installation, the limiting strip 301 needs to be spread open so that its inner diameter is larger than the outer diameter of the camera 4 to facilitate the installation. After the sleeve cavity 30 is fitted with the camera 4, the limiting strip 301 abuts against the bottom wall of the camera 4 to surround the camera 4, thereby improving the installation stability of the fastening sleeve 3.

[0048] Secondly, as attached Figure 8 and attached Figure 9As shown, the fastening sleeve 3 is made of elastic or rigid material. Multiple anti-slip strips 302 protrude from the inner wall of the sleeve cavity 30. These anti-slip strips 302 are arrayed along the axis of the sleeve cavity 30. After the camera 4 is fitted onto the sleeve cavity 30, the multiple anti-slip strips 302 simultaneously abut against the outer wall of the camera 4. This design allows the inner wall of the sleeve cavity 30 to grip the outer wall of the camera 4 more stably, thereby improving the installation stability of the fastening sleeve 3 and preventing the possibility of slippage and rotation of the fastening sleeve 3.

[0049] It should be noted that, in addition to the above-mentioned structure, the fastening sleeve 3 can also achieve a stable connection with the camera by designing other structures, which will not be listed one by one in this utility model.

[0050] See appendix Figure 3 -Appendix Figure 6 The top of the lens mount 1 is provided with a hidden groove 11 for installing the filter 2. The hidden groove 11 is connected to the opening above the mounting cavity 10. The hidden groove 11, the mounting cavity 10 and the sleeve cavity 30 are coaxially designed so that the filter 2 is coaxially fixed directly above the camera 4.

[0051] Specifically, since the same filter 2 needs to be used for multiple specifications and models, the diameter of the filter 2 usually needs to be larger than the diameter of the regular camera 4. This makes it difficult for cameras 4 of different specifications to align the center of the same specification filter 2, resulting in positional deviation. However, the coaxial design of the hidden groove 11, the mounting cavity 10 and the sleeve cavity 30 can make the filter 2 coaxially fixed directly above the camera 4, ensuring that cameras 4 of different specifications are always aligned with the center of the filter 2, avoiding positional deviation, and ensuring that the filter 2 can be used normally.

[0052] It should be noted that regarding the installation method of filter 2 and hidden groove 11, filter 2 can be directly snapped into hidden groove 11, or it can be fixed by using glue to attach the lens base 1, or even by using screws. Since there are various fixing methods, this utility model does not limit this.

[0053] See appendix Figure 5 -Appendix Figure 8 and attached Figure 10 The fastening sleeve 3 is made of elastic material and is fitted with the mounting cavity 10 with a clearance. After the camera 4 is fitted into the cavity 30, the fastening sleeve 3 deforms and the deformation of the fastening sleeve 3 is greater than the clearance value between the fastening sleeve 3 and the mounting cavity 10.

[0054] Specifically, the fastening sleeve 3 is fitted with the mounting cavity 10 with a clearance, making it easier for users to install and remove the fastening sleeve 3 within the mounting cavity 10, thus improving operational convenience. Furthermore, the deformation of the fastening sleeve 3 is greater than the clearance between the fastening sleeve 3 and the mounting cavity 10, which causes the fastening sleeve 3 to press against the inner wall of the mounting cavity 10 after deformation, ensuring that the lens mount 1 can be stably installed on the camera 4.

[0055] See appendix Figure 7 -Appendix Figure 8 and attached Figure 10 The inner diameter of the cavity 30 gradually decreases from bottom to top, so that during the process of fitting the camera 4 into the cavity 30, the camera 4 presses against the inner wall of the cavity 30, causing the fastening sleeve 3 to gradually deform, thereby making the deformed fastening sleeve 3 press against the inner wall of the mounting cavity 10. With this design, on the one hand, the user can feel the gradual locking of the lens mount 1 when moving it, improving the user experience; on the other hand, it can increase the deformation of the fastening sleeve 3 without changing the outer diameter of the fastening sleeve 3, thereby improving the installation stability of the lens mount 1.

[0056] See appendix Figure 7 -Appendix Figure 8 and attached Figure 10 The maximum inner diameter of the cavity 30 is slightly larger than the outer diameter of the camera 4. This design makes it convenient to fit the camera 4 into the cavity 30.

Conversely, some features of the present invention are described only in a single embodiment for brevity; however, these features may also be described individually or in any suitable combination in different embodiments.
