Description

Technical Field

[0001] The utility model relates to the field of rings, in particular to a decompression ring. Background Art

[0002] With the ever-accelerating pace of modern life, people often experience negative emotions such as depression, irritability, and anxiety, which have a profound impact on our daily lives. To effectively overcome the negative impact of these emotions on our lives, many people have begun to seek various methods to relieve stress. One very common and popular method is to play with various objects with segmented or openable structures, such as buttons and switches. Through this "interactive feedback" method, people can shift their attention from the source of stress to the object itself, effectively relieving stress.

[0003] Among the many decompression products, rings are widely popular due to their unique design and portability. Existing ring-type decompression products typically utilize a double-layer structure, with an outer ring nestled around an inner ring. A friction component exists between the two rings, allowing users to decompress by rubbing the outer ring. However, this method only achieves relative displacement between the outer and inner rings, lacking the frictional feel of friction between them. This results in poor decompression effectiveness and compromises the user experience.

[0004] Chinese utility model patent publication number CN220513422U discloses a decompression ring. Through magnetic fixings and magnetic adjustment components, it achieves the effect of generating different resistances and sounds when the rotating component rotates around the inner ring component. It provides a sense of friction between the outer ring and the inner ring during relative rotation, thereby improving the decompression effect for the user. However, this utility model has a complex structure, high production costs, and is inconvenient to assemble. Utility Model Content

[0039] The description of the embodiments in this specification should be combined with the corresponding drawings, which should be considered a complete part of this specification. In the drawings, the shapes and thicknesses of the embodiments may be exaggerated and indicated for simplicity or convenience. Furthermore, the various structural components in the drawings will be described separately. It is worth noting that components not shown in the drawings or not described in words are known to those of ordinary skill in the art.

[0040] The description of the embodiments herein and any references to directions and orientations are for ease of description only and are not to be construed as limiting the scope of protection of the present invention. The following description of the preferred embodiments may involve combinations of features, which may exist independently or in combination. The present invention is not specifically limited to the preferred embodiments. The scope of the present invention is defined by the claims.

[0041] like Figures 1 to 4 As shown, the utility model provides a decompression ring, comprising:

[0042] The outer ring 2 has a ball groove at the lower part of its inner side, a radial groove 22 above the ball groove, and a positioning groove 21 at the upper end of the outer ring 2;

[0043] The inner ring 1 has a positioning cover 11 on its upper end that cooperates with the positioning groove 21, and a protrusion 12 on the inner ring 1 that cooperates with the radial groove 22;

[0044] A retainer 4, which is fixedly connected to the lower end of the inner ring 1; preferably, the retainer 4 can be fixedly connected to the inner ring 1 by bonding or welding;

[0045] Multiple balls 3 are distributed between the cage 4 and the ball groove;

[0046] A magnetic insert 6 is provided on the outer surface of the inner ring 1;

[0047] The magnetic movable part 5 is used to collide with the magnetic embedded part 6 to produce sound. The magnetic movable part 5 is movably arranged on the inner side surface of the outer ring 2. The magnetic properties of the magnetic movable part 5 are opposite to those of the magnetic embedded part 6.

[0048] When the user uses the decompression ring, he rotates the outer ring 2 of the decompression ring. When the magnetic insert 6 and the magnetic movable part 5 are close to each other during the rotation, they will attract each other due to opposite magnetic properties, and the collision will produce sound. When the magnetic movable part 5 and the magnetic insert 6 separate during the rotation, rotation resistance will be generated, resulting in a sense of rotational frustration. The sound and the sense of frustration will attract the user's attention, achieving the effect of decompression.

[0049] The decompression ring of the present invention has a simple structure and low production and assembly costs. A ball groove is provided on the outer ring, and the ball groove cooperates with the retaining frame 4 fixed on the inner ring 1 to play a role similar to a bearing, so that the decompression ring can rotate without the need for special installation of bearings and other structures. A positioning groove 21 and a radial groove 22 are also provided on the outer ring 2, which cooperate with the positioning cover 11, retaining frame 4 and protrusion 12 on the inner ring to limit the position between the inner ring 1 and the outer ring 2. In addition, the positioning cover 11 and retaining frame 4 on the inner ring 1 also serve as the side cover of the ring to protect the inside of the ring. By concentrating multiple functions on one part, the number of parts is reduced to the maximum extent, and the parts are installed by embedding or snapping, which simplifies the production process.

[0050] The magnetic insert 6 and magnetic movable part 5 are positioned on the outer side of the inner ring 1 and the inner side of the outer ring 2, respectively. This allows them to attract and collide directly when approaching, resulting in a clearer and louder sound. They also provide greater rotational resistance when separated. Furthermore, a protective layer made of a specific material can be provided on the magnetic insert 6 and magnetic movable part 5 to extend their service life or to produce a distinctive sound when they collide.

[0051] In one embodiment of the present invention, the present invention only uses the inner ring 1, the outer ring 2, the retaining frame 4 and the positioning cover 11 to form the basic structure of the ring. On the one hand, it has the characteristics of simple structure. On the other hand, it also reduces the weight of the ring, so that the total mass of the decompression ring does not exceed 0.01 kg.

[0052] For example, basic ordinary carbon steel material can be used to ensure the stability of the overall structure and further reduce the weight, with the total mass being approximately between 0.006 and 0.008 kilograms.

[0053] In one embodiment of the present invention, Figure 3 As shown, a plurality of circular grooves are provided on the outer surface of the inner ring 1, and the magnetic inserts 6 are embedded in the circular grooves. The feel of the decompression ring rotation can be adjusted by adjusting the spacing and number of the circular grooves.

[0054] In some embodiments of the present invention, the magnetic movable member 5 is mounted in a movable member positioning groove 7. The magnetic movable member 5 is movably disposed within the movable member positioning groove 7. The movable member positioning groove 7 is disposed on the inner circumferential surface of the outer ring 2. The upper end of the movable member positioning groove 7 is in communication with the positioning groove 21. By having the movable member positioning groove 7 in communication with the positioning groove 21, the precision requirements for the installation of the magnetic movable member 5 can be reduced, thereby facilitating the installation of the magnetic movable member 5.

[0055] By adjusting the shape and position of the magnetic movable member 5, the duration of the collision sound can be adjusted. The volume of the collision sound and the intensity of the jerking sensation can also be adjusted by adjusting the mounting arrangement of the magnetic movable member 5 and the magnetic insert 6 relative to the outer ring 2 and inner ring 1. For example, a spring can be installed between the magnetic movable member 5 and the outer ring 2 to increase the resistance to the outer ring 2's rotation, thereby prolonging the duration of the jerking sensation and reducing its intensity.

[0056] In one embodiment of the present invention, a plurality of magnetic inserts 6 are arranged along the circumference of the inner ring 1, such as Figure 4 As shown, two magnetic movable members 5 are provided, spaced apart on the inner circumference of the outer ring 2. The spacing between the two magnetic movable members 5 is smaller than the spacing between any two adjacent magnetic inserts 6. The angle between the two magnetic movable members 5 and the line connecting the center of the outer ring 2 is 25 to 45 degrees.

[0057] By setting the distance between the two magnetic movable parts 5, the user can experience a more obvious sense of frustration when rotating the decompression ring. Because the distance between the two magnetic movable parts 5 is smaller than the distance between any two adjacent magnetic embedded parts 6, the two magnetic movable parts 5 will successively attract the same magnetic embedded part 6 to generate rotational resistance and sound during rotation, thereby producing a sound similar to clicking-clicking-clicking and a sense of frustration. According to practical investigations, this sense of frustration makes it easier for people to shift their attention to the decompression ring.

[0058] In another embodiment of the present invention, a plurality of magnetic inserts 6 are arranged along the circumference of the inner ring 1, such as Figure 5 As shown, there are three magnetic movable members 5, namely a first magnetic movable member, a second magnetic movable member, and a third magnetic movable member, which are respectively arranged in the first movable member positioning groove 71, the second movable member positioning groove 72, and the third movable member positioning groove 73;

[0059] The first and second magnetic movable members are spaced apart on the inner circumference of outer ring 2. The spacing between the first and second magnetic movable members is smaller than the spacing between any two adjacent magnetic inserts 6. The third magnetic movable member is positioned opposite the first magnetic movable member on the inner circumference of outer ring 2. The angle between the line connecting the first and second magnetic movable members and the center of outer ring 2 is 25 to 45 degrees.

[0060] The first gear is formed by the first magnetic movable part and the third magnetic movable part which are arranged relatively to each other, and the second gear is formed by the second magnetic movable part which is arranged adjacent to the first magnetic movable part. The intensity of the sense of frustration and the volume of the sound produced by the magnetic insert 6 in the first gear and the second gear are different, which increases the fun of the decompression ring and thus improves the decompression effect of the decompression ring.

[0061] In some embodiments of the present invention, a first inclined surface is provided in the radial groove 22 , and a second inclined surface cooperating with the first inclined surface is provided on the upper end surface of the protrusion 12 .

[0062] The cooperation between protrusion 12 and radial groove 22 limits the position of outer ring 2 and inner ring 1, enhancing the overall structural strength and preventing the decompression ring from disintegrating during use. A first bevel and a second bevel are provided on radial groove 22 and protrusion 12, respectively. These first and second bevels serve as guides during installation of outer ring 2 and inner ring 1, improving installation convenience and efficiency.

[0063] According to some embodiments of the present invention, the outer surface of the outer ring 2 is provided with textures.

[0064] The outer ring surface of the outer ring 2 of the decompression ring can adopt a variety of options, such as texture or special texture surface. The texture can be decorative texture, or a slightly rough texture can be used to enhance the feel during rotation. The special texture surface can be made of materials such as jade surface that are popular with target customers.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
