[0035] Example 1

[0036] like Figures 1-4 As shown, Figure 1 This is a schematic diagram of the three-dimensional structure of the filter; Figure 2 This is a breakdown diagram of the filter's state. Figure 3 This is a cross-sectional view of the filter; Figure 4 for Figure 3 Enlarged view of part A. The filter of this application includes a first frame 1, a first lens 2, and a first retaining ring 3. The first lens 2 is disposed on the first frame 1, and the first retaining ring 3 is detachably connected to the first frame 1. The first lens 2 is fixed by the cooperation between the first retaining ring 3 and the first frame 1. In use, the first frame 1 has a ring-shaped structure, that is, the first frame 1 is a hollow structure, and this hollow structure is to present the first lens 2. The first retaining ring 3 is also a ring structure, and the first retaining ring 3 is threadedly connected to the wall of the hollow structure of the first frame 1. That is to say, the connection and detachment between the first retaining ring 3 and the first frame 1 can be achieved by turning the first retaining ring 3.

[0037] In this embodiment, the first lens 2 can be made of glass or resin. The first lens 2 is an existing optical lens, such as a lens with filtering function or a polarizing lens. This filter can be used in camera lenses, drone lenses, or mobile phone lenses to improve image quality.

[0038] Review again Figures 1-4 and refer to Figure 5 , Figure 5This is a three-dimensional structural diagram of the frame 11. The first frame 1 includes a frame 11 and a snap-fit ​​assembly 12. The snap-fit ​​assembly 12 is slidably disposed on the outer surface of the frame 11, that is, the snap-fit ​​assembly 12 is exposed outside the frame 11. The first lens 2 and the first pressure ring 3 are both disposed on the frame 11. The frame 11 has a receiving groove 111, and the snap-fit ​​assembly 12 is disposed in the receiving groove 111. Specifically, the receiving groove 111 has a first wall surface 1111 and a second wall surface 1112 inside, wherein the first wall surface 1111 and the second wall surface 1112 are stepped. Furthermore, the receiving groove 111 also has a third wall surface 1113, which is disposed adjacent to the second wall surface 1112, and the third wall surface 1113 and the second wall surface 1112 are also stepped.

[0039] like Figures 2-7 As shown, Figure 6 This is a three-dimensional structural diagram of the snap-fit ​​body 121; Figure 7 This is another three-dimensional structural diagram of the snap-fit ​​body 121. The snap-fit ​​assembly 12 includes a snap-fit ​​body 121, a limiting member 122, and an elastic member 123. The snap-fit ​​body 121 is disposed in the receiving groove 111. The limiting member 122 passes through the snap-fit ​​body 121 and the frame 11, and the snap-fit ​​body 121 and the frame 11 are connected by the limiting member 122. In addition, the snap-fit ​​body 121 can move relative to the limiting member 122. The limiting member 122 and the frame 11 are detachably connected. One end of the elastic member 123 abuts against the frame 11, and the other end of the elastic member 123 abuts against the snap-fit ​​body 121. Specifically, the snap-fit ​​body 121 has a fourth wall surface 1211 and a fifth wall surface 1212. The fourth wall surface 1211 is disposed opposite to the first wall surface 1111, and the fifth wall surface 1212 is disposed opposite to the second wall surface 1112. The two ends of the elastic member 123 abut against the second wall surface 1112 and the fifth wall surface 1212, respectively. Furthermore, the fifth wall surface 1212 is provided with a receiving hole 1215, and the elastic member 123 is located in the receiving hole 1215 to fix the position of the elastic member 123. At the same time, it also helps to reduce the portion of the snap-fit ​​body 121 protruding from the frame 11, thereby reducing the overall volume of the filter.

[0040] The snap-fit ​​body 121 also has a snap-fit ​​protrusion 1213. The snap-fit ​​protrusion 1213 and the fourth wall surface 1211 are located on opposite sides of the snap-fit ​​body 121. The snap-fit ​​protrusion 1213 extends outward from the frame 11. By setting the snap-fit ​​protrusion 1213, the two filters can be assembled by snap-fit.

[0041] The snap-fit ​​body 121 also has a limiting protrusion 1214, which corresponds to the third wall surface 1113 of the receiving groove 111. The limiting member 122 passes through the limiting protrusion 1214 and the third wall surface 1113, and the limiting protrusion 1214 can move relative to the limiting member 122. Specifically, after the limiting member 122 passes through the third wall surface 1113, it is connected to the frame 11 by a screw connection to facilitate assembly and disassembly. It can be understood that in order to allow the limiting protrusion 1214 to move relative to the limiting member 122, a movable hole 1216 can be opened on the limiting protrusion 1214, and the inner diameter of the movable hole 1216 is larger than the outer diameter of the limiting member 122.

[0042] In order to achieve the screw connection between the frame 11 and the limiting member 122, a threaded hole 1114 is provided on the third wall surface 1113. In this embodiment, the limiting member 122 is a bolt or screw.

[0043] In this embodiment, the receiving groove 111 has two third wall surfaces 1113, and correspondingly, the snap-fit ​​body 121 has two limiting protrusions 1214, which correspond to the two third wall surfaces 1113 respectively; there are two limiting members 122 and two elastic members 123, with the two limiting members 122 respectively disposed on the two limiting protrusions 1214, and the two elastic members 123 respectively disposed on the two receiving holes 1215 on the fifth wall surface 1212.

[0044] In use, when the snap-fit ​​body 121 is subjected to force and moves toward the frame 11, the elastic element 123 is compressed, and the fourth wall surface 1211 and the fifth wall surface 1212 of the snap-fit ​​body 121 are respectively attached to the first wall surface 1111 and the second wall surface 1112 in the receiving groove 111. At this time, the snap-fit ​​protrusion 1213 on the snap-fit ​​body 121 retracts into the receiving groove 111. After the external force is removed, the snap-fit ​​body 121 is reset by the elastic force of the elastic element 123. At this time, the snap-fit ​​protrusion 1213 extends out of the receiving groove 111.

[0045] Preferably, there are two snap-fit ​​components 12, which are disposed opposite to each other on the outer surface of the frame 11, and the two snap-fit ​​components 12 have the same structure. The use of two snap-fit ​​components 12 improves the stability of the filter connection, and the opposite arrangement facilitates user operation and force application.

[0046] In summary, when connecting multiple filters, press the snap-fit ​​component 12. After the filter is installed in the designated position, release the snap-fit ​​component 12. The snap-fit ​​component 12 connects the filters. To remove the filters, simply press the snap-fit ​​component 12 again. This not only simplifies the assembly process but also significantly reduces assembly time, thereby improving assembly and shooting efficiency.

[0047] Example 2

[0048] like Figures 8-11 As shown, Figure 8 A schematic diagram of the three-dimensional structure of the filter system; Figure 9 This is a breakdown diagram of the filter system. Figure 10 This is a cross-sectional schematic diagram of the filter system; Figure 11 for Figure 10 Enlarged view of section B. The filter system includes an adapter 4 and a filter. The adapter 4 can be connected to products such as cameras, and the filter is connected to the adapter 4. The filter in this embodiment adopts the filter structure of Embodiment 1. The adapter 4 includes a second lens frame 41, a second lens 42, and a second retaining ring 43. The second lens frame 41 is snapped into the first lens frame 1, the second lens 42 is disposed on the second lens frame 41, and the second retaining ring 43 is detachably connected to the second lens frame 41. In specific applications, the second retaining ring 43 is screwed into the second lens frame 41, and the second lens 42 is fixed through the cooperation between the second retaining ring 43 and the second lens frame 41. The side of the second lens frame 41 away from the first lens frame 1 has an external thread, through which the adapter 4 can be connected to products such as cameras.

[0049] The second frame 41 has a slot 40, and the snap-fit ​​protrusion 1213 on the snap-fit ​​body 121 is connected to the slot 40, thereby realizing the splicing of the filter and the adapter 4.

[0050] Taking a camera as an example, when using it, first assemble the adapter 4 onto the camera, and then apply force to the two snap-fit ​​components 12, so that the two snap-fit ​​bodies 121 move into the receiving groove 111, so that the snap-fit ​​protrusions 1213 on the snap-fit ​​bodies 121 retract into the receiving groove 111. At this time, the filter can be moved to the designated position on the adapter 4. Then, remove the external force applied to the snap-fit ​​body 121. The snap-fit ​​body 121 is moved away from the receiving groove 111 by the elastic force of the elastic member 123. At this time, the snap-fit ​​protrusions 1213 will move out of the receiving groove 111 and be engaged in the slot 40. In this way, the connection between the adapter and the filter can be realized.
