[0032] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0033] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, or the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0034] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0035] An embodiment of this application provides an adapter ring 10.

[0036] Reference Figure 1 and Figure 2 The adapter ring 10 includes: a ring body 100, a pressing element 200, and a snap fastener 300.

[0037] The pressing element 200 is disposed on the ring body 100; there are multiple fasteners 300, which are disposed on the ring body 100 and are linked with the pressing element 200. The fasteners 300 are provided with a fastening block 310 for locking the lens 20.

[0038] When the pressing member 200 is pressed, the multiple latching blocks 310 move closer to or further away from each other; under the action of the resetting member 400, the pressing member 200 and the latching blocks 300 are reset.

[0039] It is understandable that, since the latching component 300 is linked with the pressing component 200, the resetting component 400 can be directly connected to the pressing component 200, that is, the force of the resetting component 400 directly acts on the pressing component 200. The resetting component 400 can also be directly connected to the latching component 300, that is, the force of the resetting component 400 directly acts on the latching component 300. Both can achieve the effect of resetting the pressing component 200 and the latching component 300 under the action of the resetting component 400.

[0040] When the user presses the pressing member 200, the locking blocks 310 on the different locking members 300 move closer or further apart, allowing the adapter ring 10 to be placed on the lens 20. When the user stops pressing the pressing member 200, the pressing member 200 and the locking members 300 reset under the action of the reset member 400, and the multiple locking members 300 work together to clamp the lens 20, thus fixing the adapter ring 10 on the lens 20.

[0041] Reference Figure 4 and Figure 5 Specifically, in one embodiment, pressing the pressing member 200 causes it to move and drive multiple locking members 300 to move. The locking blocks 310 on the multiple locking members 300 move closer to each other, that is, the distance between the multiple locking blocks 310 decreases. At this time, the multiple locking blocks 310 can be inserted into the ring of the lens 20. When the force of pressing the pressing member 200 decreases, the force of the reset member 400 on the pressing member 200 is greater than the force of pressing the pressing member 200. Under the action of the reset member 400, the pressing member 200 and the locking members 300 reset, and the locking blocks 310 on the multiple locking members 300 move further apart, that is, the distance between the multiple locking blocks 310 increases, so that the multiple locking blocks 310 can lock the inner side of the lens 20 to fix the adapter ring 10 on the lens 20. Then the filter 30 can be installed on the adapter ring 10. After the adapter ring 10 is installed on the lens 20, when it is necessary to remove the adapter ring 10 from the lens 20, the pressing member 200 is pressed. The pressing member 200 moves under the pressure, which drives the multiple locking members 300 to move. The locking blocks 310 on the multiple locking members 300 move closer to each other, and the distance between the multiple locking blocks 310 decreases. At this time, the multiple locking blocks 310 no longer lock the inside of the lens 20, and the adapter ring 10 can be removed from the lens 20. When the pressing member 200 is released, the pressing member 200 and the locking members 300 are reset under the action of the reset member 400.

[0042] In another embodiment, pressing the pressing member 200 causes it to move, which in turn moves multiple locking members 300. The locking blocks 310 on the multiple locking members 300 move away from each other, i.e., the distance between the multiple locking blocks 310 increases. At this time, the multiple locking blocks 310 can be inserted outside the lens 20. When the force of pressing the pressing member 200 decreases, the force of the reset member 400 on the pressing member 200 is greater than the force of pressing the pressing member 200. Under the action of the reset member 400, the pressing member 200 and the locking members 300 reset, and the locking blocks 310 on the multiple locking members 300 move closer to each other, i.e., the distance between the multiple locking blocks 310 decreases, so that the multiple locking blocks 310 can lock the outside of the lens 20 to fix the adapter ring 10 on the lens 20. Then the filter 30 can be installed on the adapter ring 10. After the adapter ring 10 is installed on the lens 20, when it is necessary to remove the adapter ring 10 from the lens 20, the pressing member 200 is pressed. The pressing member 200 moves under the pressure, which drives the multiple locking members 300 to move. The locking blocks 310 on the multiple locking members 300 move away from each other, and the distance between the multiple locking blocks 310 increases. At this time, the multiple locking blocks 310 no longer lock the outside of the lens 20, and the adapter ring 10 can be removed from the lens 20. When the pressing member 200 is released, the pressing member 200 and the locking members 300 are reset under the action of the reset member 400.

[0043] The adapter ring 10 can be installed on lenses 20 of different sizes through multiple clips 300 with variable distances, improving its applicability to various scenarios. In addition, users can detach and install the adapter ring 10 simply by pressing the pressing part 200, which improves the ease of installation and removal of the adapter ring 10.

[0044] The ring body 100 includes an upper ring body 100 and a lower ring body 100, which are fastened together to form a cavity. The pressing member 200, the snap-fit ​​member 300, and the resetting member 400 are housed in the cavity. The ring body 100 is provided with a notch 110, and the pressing member 200 is provided with a pressing part 210, which extends out from the notch 110.

[0045] Reference Figure 1 and Figure 3 The ring body 100 is provided with a circular light-transmitting hole 130. The pressing member 200 and the fastening member 300 protrude from the circular light-transmitting hole 130 to form a circular light-transmitting opening 140. When the filter 30 is installed in the ring body 100 at the position corresponding to the circular light-transmitting hole 130, there is no need to install it in different directions, and the angle of the filter 30 can be adjusted arbitrarily. The light transmission characteristics of the circular light-transmitting hole 130 and the circular light-transmitting opening 140 can better avoid the occurrence of dark corners.

[0046] Furthermore, the notch 110 is provided on the outer side of the ring 100, and the pressing part 210 extends outward from the ring 100. In this embodiment, the user presses the pressing member 200 with his / her finger and then presses the pressing member 200 inward from the ring 100, causing the pressing member 200 to retract from the notch 110 towards the cavity.

[0047] There are two pressing members 200, and the pressing portions 210 of the two pressing members 200 are arranged opposite to each other. In this embodiment, the user presses the pressing portion 210 of one pressing member 200 with one finger (e.g., thumb) and the pressing portion 210 of the other pressing member 200 with another finger (e.g., index finger), pressing both pressing members 200 towards the inside of the ring 100, so that the two pressing members 200 are close to each other.

[0048] Reference Figure 3 One end of the pressing component 200 is linked to a latching component 300, and the other end of the pressing component 200 is also linked to a latching component 300. Specifically, there are two pressing components 200: one pressing component 200 and another pressing component 200; and two latching components 300: one latching component 300 and another latching component 300. One end of the pressing component 200 is connected to one end of the latching component 300, and the other end of the pressing component 200 is connected to one end of the latching component 300; the other end of the pressing component 200 is connected to the other end of the latching component 300, and the other end of the pressing component 200 is connected to the other end of the latching component 300. The four components are connected in a ring. This makes the linkage between the pressing component 200 and the latching component 300 tighter and more stable.

[0049] When one pressing member 200 is pressed, it causes one latching member 300 and another latching member 300 to slide. When another pressing member 200 is pressed, it causes one latching member 300 and another latching member 300 to slide. When one pressing member 200 and another pressing member 200 are pressed simultaneously, they work together to pull the two ends of one latching member 300 and the two ends of the other latching member 300, causing them to slide.

[0050] The pressing member 200 is provided with a guide groove 220, which is straight; of course, in other embodiments, the guide groove 220 can be designed into other shapes, such as arcs, according to actual needs. The fastening member 300 is provided with a guide protrusion 320, which is a protruding rod; the guide protrusion 320 is inserted into the guide groove 220, and the guide protrusion 320 slides back and forth along the guide groove 220 to realize the movement of the fastening member 300.

[0051] The locking block 310 is provided with a threaded groove 311 that mates with the lens thread. It can be understood that the lens thread is the thread on the lens 20 used to install the filter 30, and the lens thread is located on the inner side of the lens 20; the locking block 310 has a threaded groove 311 on one side facing the outer side of the ring 100. When the locking block 310 is locked inside the lens 20, the threaded groove 311 is embedded in the lens thread, so that the adapter ring 10 can be more securely fixed on the lens 20.

[0052] The ring body 100 is provided with a receiving cavity 120, and the reset member 400 is disposed in the receiving cavity 120. The reset member 400 is a spring. When the user presses the pressing member 200, the pressing member 200 moves inward towards the ring body 100 under the pressing action, and the pressing member 200 squeezes the reset member 400, and the spring contracts; when the user stops pressing the pressing member 200, the pressing member 200 is reset by the elastic force of the reset member 400.

[0053] In one embodiment, the receiving cavity 120 for accommodating the spring is arranged along the circumferential direction of the ring 100. The spring is placed in the receiving cavity 120 along the circumferential direction of the ring 100. When the user presses the pressing member 200, the pressing member 200 moves inward towards the ring 100 under the pressing action. The pressing member 200 compresses the spring through the auxiliary member extending into the receiving cavity 120, and the spring moves and contracts along the circumferential direction of the ring 100. When the user stops pressing the pressing member 200, the pressing member 200 returns to its original position under the elastic force of the spring.

[0054] Reference Figure 9 and Figure 10 In another embodiment, the receiving cavity 120 for accommodating the spring is arranged radially along the ring body 100. The spring is placed in the receiving cavity 120 radially along the ring body 100; the pressing member 200 is provided with a protruding rod 121 that abuts against the spring. When the user presses the pressing member 200, the pressing member 200 moves inward towards the ring body 100 under the pressing action, and the pressing member 200 compresses the spring through the protruding rod 121, causing the spring to move and contract radially along the ring body 100; when the user stops pressing the pressing member 200, the pressing member 200 returns to its original position under the elastic force of the spring.

[0055] Both sides of the pressing member 200 are provided with reset members 400. The reset members 400 on both sides apply force to both sides of the pressing member 200 at the same time, so that the force on the pressing member 200 is more even and the stability of the pressing member 200 reset is improved.

[0056] Reference Figure 11In another embodiment, a reset member 400 is disposed within a pressing portion 210, which is provided with a ferrule 410. The end of the spring is fitted into the ferrule 410, and the spring is fixed by the ferrule 410 to prevent the spring from shifting position. This can lengthen the spring stroke, thereby providing sufficient stroke to achieve a wide range of side diameters within the same diameter.

[0057] The fastener 300 has a protruding rib on the side near the circular light-transmitting opening 140. The rib acts as a light-blocking element, which can effectively improve the light leakage problem.

[0058] The ring 100 is provided with a magnetic suction element 101. The magnetic suction element is a magnet. When the filter 30 is provided with another magnet, the filter 30 is magnetically attracted to the adapter ring 10 through the magnetic attraction between the magnet of the ring 100 and the magnet of the filter 30, which enables quick installation and removal of the filter 30.

[0059] Reference Figure 6 , Figure 7 and Figure 8 In another embodiment, the adapter ring can be fitted with circular mirrors of different diameters, such as a 95mm diameter circular mirror and an 82mm diameter circular mirror.

[0060] Reference Figure 9 and Figure 10 The ring 100 is equipped with multiple magnets arranged in a ring. The magnetic attraction of the multiple magnets attracts a 95mm diameter magnetic circular mirror 32.

[0061] The inner ring of the ring body is provided with a thread 102, and an 82-diameter threaded circular mirror 31 is assembled through the thread 102 of the inner ring.

[0062] The above is a detailed description of the preferred embodiments of this application, but this application is not limited to the embodiments.
