[0045] The adapter ring 10 and the adapter matching ring 20 are rotationally matched, the first clamping part and the second clamping part are slidingly matched, and when the adapter ring 10 rotates relative to the adapter matching ring 20, the first clamping part moves relative to the second clamping part, so that the adapter structure can be switched between the assembled state and the disassembled state.

[0046] In the technical scheme of the utility model, the adapter structure includes an adapter ring 10 and an adapter cooperating ring 20, the adapter ring 10 is used for connecting a filter, wherein the inner peripheral wall 10a of the adapter ring 10 is provided with a first clamping part, the outer peripheral wall 20A of the adapter cooperating ring 20 is provided with a second clamping part matched with the first clamping part, when the adapter cooperating ring 20 is screwed into the adapter ring 10 along a first rotation direction, the first clamping part clamps the second clamping part, so that the adapter ring 10 is fixedly connected with the adapter cooperating ring 20, then the adapter ring 10 is screwed out along a second rotation direction opposite to the first rotation direction, so that the first clamping part is separated from the second clamping part, through different rotation directions, the adapter structure is switched back and forth between an assembled state and a disassembled state; and when the adapter structure is in the assembled state, due to the constraint effect between the first clamping part and the second clamping part, the loosening problem between the adapter ring 10 and the adapter cooperating ring 20 can be effectively prevented, so that the stability of the filter to the lens is ensured.

[0049] The adapter ring 10 can surround the outer peripheral wall 20A of the adapter matching ring 20 to reduce the distance between the adapter ring 10 and the shell structure, compress the occupied space, and maximize the distance between the filter and the lens, thereby improving the shooting effect; one side of the adapter matching ring 20 is used to connect the shell structure at the mobile terminal lens, and can be fixedly connected to the adapter shell 1000 through an adhesive process or an integral molding process; the other side is provided with a second clamping part matched with the first clamping part, and the second clamping part can be provided in different forms corresponding to the first clamping part, for example, when the first clamping part is a virtual groove structure, the second clamping part provided on the outer peripheral wall 20A of the adapter matching ring 20 is a solid protruding strip structure, so that the user rotates the adapter ring 10, and the virtual groove structure and the solid protruding strip structure are clamped with each other to make the adapter structure enter the assembled state; similarly, the adapter ring 10 is reversely rotated, the first clamping part moves relative to the second clamping part, and after a certain angle is rotated, the first clamping part is separated from the second clamping part to make the adapter structure enter the disassembled state; of course, when the first clamping part is a solid protruding strip structure, the second clamping part is a virtual groove structure, and the corresponding matching relationship is as shown above, which will not be explained here; it can be understood that the solid protruding strip structure and the virtual groove structure can be replaced with each other, so the first clamping part and the second clamping part will not be limited here; in another embodiment, the first clamping part can be a meshing tooth structure, and the second clamping part is also a meshing tooth structure, so that the first clamping part can meshingly connect the second clamping part to realize the rotatable detachable connection between the adapter ring 10 and the adapter matching ring 20.

[0051] In this embodiment, the first clamping part is a limiting slot 10b, specifically, a groove structure is formed on the inner peripheral wall 10a of the adapter ring 10, and the groove structure forms the limiting slot 10b; as shown in Figure 6 can be known, after the limiting slot 10b is formed on the inner peripheral wall 10a of the adapter ring 10, a rib structure is formed on the inner peripheral wall 10a of the adapter ring 10 at the limiting slot 10b, and the rib structure is part of the inner peripheral wall 10a of the adapter ring 10; the second clamping part is a limiting arm 200, specifically, a protruding structure is arranged on the outer peripheral wall 20A of the adapter matching ring 20, and the protruding structure forms the limiting arm 200; the protruding structure protrudes from the outer peripheral wall 20A of the adapter matching ring 20, and the protruding structure and the adapter matching ring 20 are an integral molding structure; as shown in Figure 8It can be known that when the limiting insertion arm 200 is arranged on the outer peripheral wall 20A of the adapter matching ring 20, the limiting insertion arm 200 and the outer peripheral wall 20A of the adapter matching ring 20 form a clamping groove, when the adapter ring 10 and the adapter matching ring 20 are rotationally connected, the limiting insertion arm 200 is clamped in the limiting insertion slot 10b, the rib structure is clamped in the clamping groove, and at the same time, in order to realize the tight connection between the adapter ring 10 and the adapter matching ring 20, the limiting insertion arm 200 can abut against the rib structure, so that the gap between the adapter ring 10 and the adapter matching ring 20 is reduced, and loosening is prevented; further, the limiting insertion arm 200 and the limiting insertion slot 10b are arranged along the rotation direction, so that the contact area between the limiting insertion arm 200 and the limiting insertion slot 10b is increased, the connection reliability between the adapter ring 10 and the adapter matching ring 20 is improved, and the loosening problem of the two is reduced, so as to affect the shooting effect.

[0052] In an embodiment of the present application, the adapter ring 10 is provided with a plurality of limiting insertion slots 10b, and the plurality of limiting insertion slots 10b are arranged at intervals along the inner peripheral wall 10a of the adapter ring 10; the outer peripheral wall 20A of the adapter matching ring 20 is provided with a plurality of limiting insertion arms 200, and each limiting insertion slot 10b is inserted into one limiting insertion slot 10b.

[0053] In the embodiment, in order to further improve the connection reliability between the adapter ring 10 and the adapter matching ring 20, the adapter ring 10 is provided with at least two limiting insertion slots 10b, and in combination with Figure 6 and Figure 7 , three limiting insertion slots 10b are arranged at intervals along the inner peripheral wall 10a of the adapter ring 10, and at the same time, the outer peripheral wall 20A of the adapter matching ring 20 is provided with a corresponding number of limiting insertion arms 200, the adapter ring 10 is rotated to enable each limiting insertion slot 10b to be inserted into one limiting insertion slot 10b, so that a plurality of clamping regions are formed between the adapter ring 10 and the adapter matching ring 20, and the loosening problem of the adapter structure is effectively prevented.

[0054] In an embodiment of the present application, the inner peripheral wall 10a of the adapter ring 10 further comprises a plurality of assembly channels 10C, the plurality of assembly channels 10C are arranged at intervals along the inner peripheral wall 10a of the adapter ring 10, and each assembly channel 10C is adjacent to and communicates with one limiting insertion slot 10b.

[0055] In the embodiment, the assembly channel 10C is arranged along the axial direction of the adapter ring 10, so that the assembly channel 10C provides sufficient space for the limiting insertion arm 200 of the adapter matching ring 20 when the adapter ring 10 and the adapter matching ring 20 are assembled. During the process that the adapter ring 10 and the adapter matching ring 20 are close to each other and are fitted, the limiting insertion arm 200 is positioned on the assembly channel 10C and moves along the extension direction of the assembly channel 10C. Then, the limiting insertion arm 200 is positioned in the limiting insertion slot 10b in the assembly channel 10C. Then, the adapter ring 10 is rotated, the limiting insertion arm 200 enters the limiting insertion slot 10b, and the clamping and fixing between the adapter ring 10 and the adapter matching ring 20 are realized.
