Description

Technical Field

[0001] This utility model relates to the field of decompression toy technology, specifically a hand-held decompression wheel. Background Technology

[0002] Stress-relieving toys are a type of toy that helps users release stress, alleviate anxiety, or improve concentration through physical manipulation (such as squeezing, kneading, rotating, and combining). In recent years, hand-held stress-relieving toys have become increasingly popular due to their effectiveness in relieving anxiety. Common stress-relieving toys in existing technology include fidget spinners, squeeze toys, and deformable silicone balls. However, these existing technologies still have the following drawbacks:

[0003] Insufficient dynamic interactivity: Traditional decompression toys (such as squeeze toys and press balls) rely solely on elastic deformation after unidirectional force application, lacking the continuous dynamic operation feel of "playing with walnuts", which can easily lead to user boredom.

[0004] Limited hand coordination: Existing spinning toys (such as fidget spinners) only trigger visual feedback through single-axis rotation, and cannot simulate the two-way interactive feedback of multi-axis alternating motion. Utility Model Content

[0005] This invention provides a hand-held decompression wheel to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hand-held decompression wheel, comprising a decompression wheel body, the decompression wheel comprising a plurality of steel shafts and a connector for connecting the plurality of steel shafts together in parallel, a silicone sleeve being movably fitted on both ends of the steel shafts, and a bearing being provided on both ends of the silicone sleeves.

[0007] Furthermore, the bearing includes a large bearing and a small bearing respectively nested inside both ends of the silicone sleeve.

[0008] Furthermore, a fitting ring is provided at the middle position of the surface of the steel shaft, and the inner hole of the connector is interference-fitted with the fitting ring.

[0009] Furthermore, the steel shaft surface is provided with assembly ring one, assembly ring two, assembly ring three and assembly ring four on both sides of the tight fitting ring.

[0010] Furthermore, the assembly ring two is transitionally fitted with the inner hole two inside the large bearing.

[0011] Furthermore, the assembly ring three transitions into the inner bore three inside the small bearing.

[0012] Furthermore, it also includes an end cap, the inner hole of which is interference-fitted with the assembly ring.

[0013] Furthermore, one end of the end cap is provided with a decorative cap for covering one end of the silicone sleeve.

[0014] Furthermore, both the connector and the end cap are made of aluminum alloy.

[0015] Furthermore, both the fitting ring and the assembly ring are provided with knurling.

[0016] Compared with the prior art, this utility model provides a hand-held decompression wheel, which has the following beneficial effects:

[0017] This hand-held stress-relieving wheel works by rubbing silicone sleeves on two steel shafts in a "walnut-playing" motion. As the silicone sleeves rotate, the two steel shafts exchange positions, simulating the "walnut-playing" action. This enhances the dynamic interaction of the hand and extends the user's focus time. The combination of silicone sleeves and bearings provides a smooth rotational feel, relieving hand muscle tension and achieving stress relief. The aluminum alloy coating on the steel shafts ensures a better fit and greater stability, increases product weight, and improves product quality. The structure is simple and compact, making it economical and promising for broad applications. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 This utility model discloses a hand-held stress-relieving wheel, including a stress-relieving wheel body 1. The stress-relieving wheel includes several steel shafts 11 and a connector 12 for connecting the steel shafts 11 in parallel. Each end of the steel shaft 11 is movably fitted with a silicone sleeve 13, and each end of the silicone sleeve 13 is provided with a bearing. The number of inner holes 121 inside the connector 12 is the same as the number of steel shafts 11. When there are three steel shafts 11, there are three inner holes 121. The three steel shafts 11 can be connected in parallel through the connector 12, and so on. When playing with the stress-relieving wheel body 1, the stress-relieving wheel body 1 is placed in the hand, and the silicone sleeves 13 on the two steel shafts 11 are rubbed in the manner of "playing with walnuts". The silicone sleeves 13 rotate while the two steel shafts 11 exchange positions, simulating the "playing with walnuts" action. The combination of the silicone sleeves 13 and the bearings provides a smooth rotational feel, relieves hand muscle tension, and achieves stress relief.

[0027] Specifically, the bearings include a large bearing 131 and a small bearing 132, which are respectively nested inside both ends of the silicone sleeve 13.

[0028] In this embodiment, the two ends of the silicone sleeve 13 are in contact with the steel shaft 11 through the large bearing 131 and the small bearing 132. This design makes the silicone sleeve 13 rotate more flexibly on the steel shaft 11 without jamming. Both the large bearing 131 and the small bearing 132 are silent bearings, so that the silicone sleeve 13 will not make any noise during rotation.

[0029] Specifically, a fitting ring 111 is provided at the middle position of the surface of the steel shaft 11, and the inner hole 121 inside the connector 12 is interference-fitted with the fitting ring 111.

[0030] In this embodiment, the fitting ring 111 is provided with knurling. The fitting ring 111 is connected to the inner hole 121 by knurling interference fit. The surface of the fitting ring 111 is formed with regular teeth by knurling process. The inner hole 121 adopts a smooth inner hole or a matching groove design. During assembly, the fitting ring 111 and the inner hole 121 are connected by interference fit, so that the knurling pattern is embedded into the inner wall of the inner hole 121, forming a mechanical engagement. The contact surface with the inner hole 121 generates high friction, realizing torque transmission and axial fixation without the need for additional fasteners.

[0031] Specifically, on both sides of the steel shaft 11, there are assembly rings 112, 113, 114 and 115 arranged in sequence.

[0032] In this embodiment, the diameters of assembly ring 112, assembly ring 213, assembly ring 314, and assembly ring 415 decrease sequentially.

[0033] Specifically, the second assembly ring 113 is transitionally fitted with the second inner hole 133 inside the large bearing 131, and the third assembly ring 114 is transitionally fitted with the third inner hole 134 inside the small bearing 132.

[0034] In this embodiment, when the basic size difference between the assembly ring 113 and the inner hole 133 is zero, if the tolerance zones of the two overlap, there may be both gaps or interferences, which is a transition fit. No strong pressing is required during assembly, and the resistance is small during disassembly, making it more convenient to assemble the silicone sleeve 13.

[0035] Specifically, it also includes an end cap 14, wherein the inner hole 141 inside the end cap 14 is interference-fitted with the assembly ring 115.

[0036] In this embodiment, the assembly ring 115 is provided with knurling, and the surface of the assembly ring 115 is formed with regular teeth through the knurling process. The inner hole 141 adopts a smooth inner hole or a matching groove design. During assembly, the assembly ring 115 and the inner hole 141 are press-fitted to make the knurling pattern embedded in the inner wall of the inner hole 141, forming a mechanical engagement. The contact surface with the inner hole 141 generates high friction, realizing torque transmission and axial fixation without the need for additional fasteners. After the end cover 14 is fixed, one end of the end cover 14 blocks the small bearing 132, limiting the silicone sleeve 13 and further ensuring the stability of the silicone sleeve 13 during rotation.

[0037] Specifically, one end of the end cap 14 is provided with a decorative cap 142 for covering one end of the silicone sleeve 13.

[0038] In this embodiment, the decorative cap 142 is used to cover one end of the silicone sleeve 13, thereby improving the overall appearance of the product.

[0039] Specifically, both the connector 12 and the end cap 14 are made of aluminum alloy.

[0040] In this embodiment, aluminum alloy has a slightly lower hardness than steel, and the aluminum alloy wrapping around the steel shaft 11 makes its fit better and more stable.

[0041] Specifically, both the tight-fitting ring 111 and the assembly ring 115 are provided with knurling.

[0042] In this implementation plan, a knurled interference fit connection is adopted. Compared with the traditional snap-fit ​​connection, the knurled interference fit connection is easier to process and saves costs.

[0043] In summary, this hand-held stress-relieving wheel uses a "playing with walnuts" motion, rubbing the silicone sleeves 13 on the two steel shafts 11. As the silicone sleeves 13 rotate, the two steel shafts 11 exchange positions, simulating the "playing with walnuts" action, enhancing the dynamic interaction of the hand, and extending the user's focus time. The silicone sleeves 13 combined with the bearings provide a smooth rotational feel, relieving hand muscle tension and achieving stress relief. The aluminum alloy wrapping of the steel shafts 11 makes its fit better and more stable, increases the product weight, and improves the product's texture. The structure is simple and compact, economical, and has broad application prospects.
