[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. The following description of at least one exemplary embodiment is actually only illustrative, but not as any limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0038] In order to solve the problem that the ring device of the ring device is easy to fall off in the prior art, the present application provides a ring device.

[0039] Embodiment one

[0040] As Figures 1 to 5As shown, the ring device includes a ring device 10 and a ring sleeve 20, wherein the ring device 10 has a clamping groove 12, and the direction of the slot of the clamping groove 12 is different from the direction of the finger insertion; the ring sleeve 20 has at least one disassembly end, and the disassembly end is provided with a clamping structure 21 which is clamped and matched with the clamping groove 12.

[0041] By setting the clamping groove 12 on the ring device 10, and setting the direction of the slot of the clamping groove 12 to be different from the direction of the finger insertion, and setting at least one disassembly end on the ring sleeve 20, when the ring sleeve 20 and the ring device 10 are assembled, the clamping structure 21 at the disassembly end of the ring sleeve 20 is clamped and matched with the clamping groove 12, so as to realize the clamping and matching of the ring sleeve 20 and the ring device 10, and the difference between the clamping mode of the ring sleeve 20 and the ring device 10 provided by the present application and the existing sliding clamping mode is that the disengagement direction of the ring sleeve 20 from the ring device 10 is inconsistent with the direction of the finger insertion and exit, and when the finger disengages from the ring device, the phenomenon that the ring device 10 is caused to fall off due to the ring sleeve 20 being taken out by the finger under the action of external force or inertia does not occur, thereby ensuring the connection stability between the two.

[0042] Preferably, the ring sleeve 20 is made of silicone rubber material and is integrally formed by injection molding, which not only increases the comfort of use, but also ensures the durability of the ring sleeve 20.

[0043] It should be noted that in the present application, the slot of the clamping groove 12 includes an entrance area 121 and a clamping area 122, and the clamping structure 21 enters the clamping area 122 and is clamped therein after extending into the clamping groove 12 through the entrance area 121. In this way, the clamping structure 21 at the disassembly end of the ring sleeve 20 enters the clamping area 122 and is clamped therein after extending into the clamping groove 12 through the entrance area 121, thereby realizing the clamping and matching of the ring sleeve 20 and the ring device 10.

[0044] As shown in the drawings, Figure 5 The slot cross section of the clamping groove 12 in the thickness direction of the ring device 10 is in the shape of a waist or a long strip. In this way, it is ensured that the clamping groove 12 can provide sufficient rotation space for the clamping structure 21.

[0045] It should be noted that in the present application, as shown in the drawings, Figures 1 to 7 The clamping structure 21 is rotatably arranged in the clamping groove 12 to switch between the clamping area 122 and the entrance area 121. In this way, the operator only needs to extend the clamping structure 21 into the clamping groove 12 through the entrance area 121 before wearing the ring device, and then enter the clamping area 122 in a rotating manner and be clamped therein, thereby ensuring the assembly convenience of the ring device.

[0046] It should be noted that in an embodiment not shown in the drawings, the clamping structure 21 is slidably arranged in the clamping groove 12 to switch between the clamping area 122 and the entrance area 121. In this way, the operator only needs to extend the clamping structure 21 into the clamping groove 12 through the entrance area 121, and then slide into the clamping area 122 and clamp in the clamping area 122 before wearing the ring device, ensuring the convenience of assembly of the ring device.

[0047] As shown in Figure 3 , the length L1 of the slot at the clamping area 122 of the clamping groove 12 is less than the length L2 of the slot at the entrance area 121. In this way, it is ensured that the clamping structure 21 can smoothly extend into the clamping groove 12 through the slot at the clamping area 122, and that the edge of the slot at the entrance area 121 can provide a limiting action for the clamping structure 21 clamped in the clamping area 122.

[0048] As shown in Figure 3 , the clamping area 122 is arranged close to the edge of the ring device 10 relative to the entrance area 121. In this way, it is ensured that the entrance area 121 can be closer to the wearing space 30 surrounded by the ring sleeve 20 and the ring device 10 than the clamping area 122, so that at least part of the entrance area 121 can be shielded when the finger extends into the wearing space 30.

[0049] As shown in Figure 3 , the ring device 10 also has a contact surface 111 for contacting the finger, and the clamping groove 12 is arranged on the contact surface 111. In this way, the slot of the clamping groove 12 can be shielded when the finger extends into the wearing space 30, that is, the disengagement direction of the ring sleeve 20 relative to the ring device 10 is different from the direction in which the finger extends into and exits the wearing space 30.

[0050] As shown in Figure 3 , the wearing space 30 surrounded by the ring sleeve 20 and the ring device 10, the direction of the slot at the clamping area 122 is different from the direction of the slot at the entrance area 121, and at least the direction of the slot at the entrance area 121 is towards the wearing space 30. In this way, the direction of the slot at the entrance area 121 is further limited, and when the finger is in the wearing space 30, the finger plays a limiting action on the ring sleeve 20 to prevent the ring sleeve 20 from disengaging from the slot at the entrance area 121.

[0051] As shown in Figure 3 , the ring device 10 further comprises a limiting clamping jaw 13 arranged at the slot of the clamping area 122 and clamped with the clamping structure 21. In this way, the limiting clamping jaw 13 plays a role of clamping with the clamping structure 21, ensuring the stability of the connection between the ring sleeve 20 and the ring device 10.

[0052] It should be noted that, in order to further ensure the clamping reliability between the limiting clamping jaw 13 and the clamping structure 21, as shown in Figure 3 , the limiting clamping jaw 13 protrudes towards the direction of the entrance area 121.

[0053] Specifically, the head of the clamping structure 21 is used to extend into the clamping groove 12 through the entrance area 121, after the clamping structure 21 is pushed into place, the tail of the clamping structure 21 is clamped with the slot at the clamping area 122, and the end surface of the disassembly end is abutted with the surface at the clamping area 122.

[0054] As shown in Figure 2 and Figure 4 , the clamping structure 21 includes a connecting rib 211 and a clamping column 212, wherein one end of the connecting rib 211 is connected with the end surface of the disassembly end to form the tail of the clamping structure 21; the outer peripheral surface of the clamping column 212 is connected with the other end of the connecting rib 211 to form the head of the clamping structure 21, and the axis of the clamping column 212 is arranged along the axial direction of the wearing space 30 surrounded by the ring sleeve 20 and the ring device 10.

[0055] As shown in Figure 3 and Figure 4 , the connecting rib 211 is two, the two connecting ribs 211 are arranged in the axial direction of the clamping column 212, and the limiting gap 100 is formed between the two connecting ribs 211; the ring device 10 further includes a limiting clamping jaw 13, which is arranged at the slot of the clamping area 122, and after the clamping structure 21 is pushed into place, the limiting clamping jaw 13 extends into the limiting gap 100. In this way, after the limiting clamping jaw 13 extends into the limiting gap 100, the two are connected together in a clamping manner, ensuring the stability of the connection between the ring sleeve 20 and the ring device 10.

[0056] As shown in Figure 3 , the surface of the limiting clamping jaw 13 towards the side of the disassembly end also has an arc convex surface 131, which abuts with the end surface of the disassembly end when rotating the clamping structure 21, and lifts the clamping structure 21, during the lifting process of the clamping structure 21, the clamping structure 21 located in the clamping groove 12 will move upwards until the supporting surface 200 abuts with the end surface of the disassembly end.

[0057] As shown in Figures 3 to 5 , the diameter of the clamping column 212 is greater than the slot width D1 at the entrance area 121, and the clamping column 212 extends into the clamping groove 12 through the slot at the entrance area 121 by extrusion deformation. In this way, the clamping column 212 is prevented from being pulled out of the slot at the entrance area 121.

[0058] As shown in Figures 1 to 5As shown, the ring sleeve 20 further comprises a shielding cover plate 22, which is arranged at the dismounting end and extends along the extension direction of the inner wall surface of the ring sleeve 20, and the shielding cover plate 22 is smoothly connected with the inner wall surface of the ring sleeve 20. When the ring sleeve 20 is installed in place with the ring device 10, the shielding cover plate 22 simultaneously shields the slot opening of the clamping groove 12. In this way, the shielding cover plate 22 plays a shielding role on the slot opening of the clamping groove 12, preventing the slot opening of the clamping groove 12 from rubbing against the fingers and causing injuries to the fingers. In addition, the shielding cover plate 22 is smoothly connected with the inner wall surface of the ring sleeve 20, making the connection between the ring sleeve 20 and the ring device 10 more smooth, and increasing the comfort of use.

[0059] It should be noted that in the present application, as Figure 5 shown, when the ring sleeve 20 is installed, the shielding cover plate 22 will interfere with the contact surface 111 of the ring device. In order to ensure the smoothness of the installation of the ring sleeve 20, the shielding cover plate 22 is supported by a resilient material to be deformable when the ring sleeve 20 is installed.

[0060] As Figure 5 shown, the slot opening of the clamping groove 12 has a lap-inset boss 1211 for supporting the shielding cover plate 22. In this way, the shielding cover plate 22 is supported in the lap-inset boss 1211, and the lap-inset boss 1211 plays a limiting role on the shielding cover plate 22, so that the shielding cover plate 22 is limited in the lap-inset boss 1211 and kept in the same plane with the arc-shaped surface, without causing scratching or other use problems, and increasing the comfort of use.

[0061] As Figures 1 to 3 shown, the ring device 10 further has a contact surface 111 for contacting the fingers, the ring device 10 has a protruding mounting portion 11, at least a part of the surface of the protruding mounting portion 11 serving as the contact surface 111, and the contact surface 111 is an arc-shaped surface, the entry region 121 is arranged at the arc-shaped surface, and the clamping region 122 is located at a supporting surface 200 adjacent to the arc-shaped surface, wherein, when the ring sleeve 20 is connected with the ring device 10, the end surface of the dismounting end of the ring sleeve 20 abuts against the supporting surface 200.

[0062] As Figure 3 and Figure 4 shown, the ring sleeve 20 has a semi-ring structure, and the ring sleeve 20 has two dismounting ends, each of which is provided with a clamping structure 21, and the two ends of the protruding mounting portion 11 are respectively provided with one clamping groove 12, and the two clamping grooves 12 are correspondingly arranged with the two clamping structures 21, so that the ring sleeve 20 is detachably connected with the ring device 10. In this way, the convenience of dismounting the ring sleeve 20 from the ring device 10 is ensured, and since the ring sleeve 20 can be dismounted from the ring device 10, it is convenient for the operator to install the ring sleeve 20 of a corresponding size according to the size of his / her fingers, greatly improving the application range of the ring device.

[0063] It is noted that, in the present application, in order to ensure the connection stability between the ring sleeve 20 and the ring device 10, as shown in Figures 1 to 5 the supporting surface 200 is adapted to the end surface of the dismounting end; the supporting surface 200 is a plane. In this way, it is ensured that the contact surface between the supporting surface 200 and the end surface of the dismounting end is large enough, i.e. the surface contact between them, so as to ensure the abutting reliability between the supporting surface 200 and the end surface of the dismounting end.

[0064] Embodiment Two

[0065] It is noted that the difference between the present embodiment and Embodiment One is that, as shown in Figure 6 and Figure 7 the supporting surface 200 is a curved surface. It is ensured that the contact surface between the supporting surface 200 and the end surface of the dismounting end is large enough, i.e. the surface contact between them, so as to ensure the abutting reliability between the supporting surface 200 and the end surface of the dismounting end.
