Description

Technical Field

[0001] This invention relates to the field of fidget spinner toys, and particularly to a split-type fidget spinner with an adjustable diameter. Background Technology

[0002] Fidget spinners are a type of toy, commonly made of plastic or metal. Currently, high-end fidget spinners feature a single, machined metal rotating part. For example, in August 2025, the "Arrogant Old Blacksmith" shop on Taobao sold a noisy fidget spinner consisting of a rotating part, bearings, and a locking mechanism; its rotating part was a single, four-bladed unit. On Bilibili, a video titled "Want to Try a Foldable Fidget Spinner?" uploaded on October 24, 2024, by the author "Rational NINI," showcased over ten different fidget spinners, all with a single, integrated rotating part.

[0003] One type of fidget spinner is the open-armor spinner. Besides the main spinning body, it has an open-armor section mounted on it. When the spinner spins, the open-armor section moves due to centrifugal force, producing more sound, light, and force feedback effects. For example, the Garlic QS tuning fork-type open-armor spinner sold by the Zhiwanwu store on Taobao in August 2025 has a three-bladed integrated rotating body, with open-armor blades added to this base. On Bilibili, a video titled "First Challenge with a Gear-Linked Open-Armor Spinner! Phantom Refinement EDC's New Product 'Explosion', Full Disassembly and Review!" was uploaded by author Ryan EDC on July 10, 2024. The article showcases a spinning top called "Explosion," whose complex peripheral structure requires individual processing and assembly before being screwed onto the main spinning body. The assembly method lacks a single blade fixing device for easy disassembly and reassembly of all the blades, making it unsuitable for general consumers to disassemble and modify. Furthermore, the separately installed parts are functional extension components, providing additional play options such as opening the shell and twisting, and do not fall under the conventional definition of spinning top blades. In August 2025, the "Baby Joy Toys" store on Pinduoduo sold a pure copper metal colorful fidget spinner. Its main body featured multiple threaded cylinders that could be disassembled, but the connection method was not secure. Different screwing forces resulted in varying depths of connection between the cylinders, leading to different dynamic balances. Users found it difficult to adjust the balance, and the screwed parts were prone to loosening during use, causing the spinner's dynamic balance to constantly change.

[0004] To accommodate different hand sizes, many fidget spinners with the same design also offer larger and smaller diameter versions, increasing inventory variety. Furthermore, consumers cannot experience the feel of both a small-diameter and a large-diameter fidget spinner when purchasing only one model. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a split-type fidget spinner that is easy and reliable to assemble and disassemble and allows for convenient adjustment of the spinner diameter.

[0006] One of the technical solutions to achieve the purpose of this invention is to provide a split-type fidget spinner with an adjustable gyroscope diameter, including a body and at least two blades, the blades being detachably connected to the circumference of the body, and all blades being dynamically balanced. The bottom plate of the main body is provided with multiple blade connecting grooves; the inner end of the blade is provided with a mounting part, and the blade is mounted on the main body by connecting the mounting part to the corresponding blade connecting groove; The blade connecting slot has radial limiting structures located at different radial positions on the body. The radial limiting structures at the same radial position of all blade connecting slots form each ring. The blades can be inserted into the corresponding rings of the blade connecting slots on the body by their mounting parts according to the overall diameter of the gyroscope, thus forming split-type fidget gyroscopes of different diameters.

[0007] Furthermore, the blade connecting groove is a multi-T-shaped overlapping groove with at least two transverse sides that opens outward and upward, that is, multiple T-shaped grooves share a groove part facing the outer circumferential side of the body, and the transverse side is a radial limiting structure. The blade mounting part corresponds to the largest T-shaped groove of the blade connecting groove and forms a T-shape; the blade connecting groove has T-shaped grooves of different lengths in the radial direction of the body through multiple radial limiting structures distributed from the inside to the outside, so that the body has rings of different diameters; by inserting the blade into the corresponding ring of the blade connecting groove from its mounting part, and using different radial limiting structures to radially limit the blade, a split-type fidget spinner with a suitable diameter can be assembled.

[0008] Furthermore, the aforementioned adjustable gyroscope diameter split-type fidget spinner also includes a blade limiting plate; a blade limiting part is provided along the upper edge of the bottom plate of the main body, and the blade limiting part is connected to the middle of two adjacent blade connecting grooves; the blade limiting plate is detachably installed on the blade limiting part from the front to limit the front and back of the blade.

[0009] Furthermore, the base plate of the main body is set as a disc; the blade limiting part is annular; the blade limiting part is provided with internal thread; the blade limiting disk is annular, the size of the blade limiting disk corresponds to the blade limiting part, the rear end face of the blade limiting disk is provided with a neck, the neck is provided with an external thread corresponding to the internal thread of the blade limiting part; the blade limiting disk is screwed into the blade limiting part of the main body from the front to limit the blade front and rear.

[0010] Furthermore, the aforementioned adjustable gyroscope diameter split-type fidget spinner also includes a bearing and a locking mechanism; the main body has a through bearing hole in the center; the bearing size corresponds to the bearing hole of the main body, and the thickness corresponds to the base plate of the main body; the bearing has a central through hole; the bearing is inserted into the bearing hole of the main body through an interference fit; the locking mechanism includes a detachable upper locking mechanism and a lower locking mechanism connected front and back, the size of the locking mechanism cover plate corresponds to the base plate of the main body; the lower locking mechanism passes through the center of the bearing and is tightly connected to the upper locking mechanism to seal the main body.

[0011] The second technical solution to achieve the purpose of this invention is to provide a split-type fidget spinner body with an adjustable gyroscope diameter, wherein the bottom plate edge of the body is provided with multiple blade connecting grooves. The blade connecting slot has radial limiting structures located at different radial positions on the body, and the radial limiting structures at the same radial position of all blade connecting slots form each concentric ring.

[0012] Furthermore, the blade connecting groove is a multi-T-shaped overlapping groove with at least two transverse sides that opens outward and upward, that is, multiple T-shaped grooves share a groove part facing the outer circumferential side of the body, and the transverse side is a radial limiting structure. The blade connecting groove has T-shaped grooves of different lengths in the radial direction of the body through multiple radial limiting structures distributed from the inside to the outside, thus the body has layers with different diameters.

[0013] The present invention has the following positive effects: (1) The present invention provides a split-type fidget spinner with adjustable gyroscope diameter, which can reduce production and inventory costs. Compared with previous fidget spinners, if it is necessary to produce a product with the same style but different diameters to suit users with different hand sizes, multiple CNC machining programs need to be developed and multiple inventories need to be set up, thereby increasing production costs and inventory funds. The present invention adopts a split-type fidget spinner design with adjustable gyroscope diameter, which only requires the production of one gyroscope body and one gyroscope blade. There is no need to develop multiple CNC machining programs or set up multiple inventories. After receiving the product, users can adjust the diameter of the gyroscope by inserting the blade into the radial limiting structure at different radial positions in the blade connecting groove according to their own hand size.

[0014] (2) The adjustable diameter split-type fidget spinner of the present invention increases the playability of the spinner. Different diameter spinners can bring different user experiences. If a traditional one-piece or split-type spinner design is adopted, the user needs to spend money to buy multiple fidget spinners or fidget spinner bodies. With the adjustable diameter split-type fidget spinner design, the user can easily choose the blades to be radially limited by different blade connecting groove radial limiting structures. By purchasing only one spinner, the user can experience the different user experiences brought by spinners of various diameters, thus increasing the playability of the spinner.

Detailed Implementation

[0017] See Figures 1 to 4 The split-type fidget spinner of this embodiment includes blades 1, a body 2, a bearing 3, a locking mechanism 4, and a blade limiting disc 5. The body 2 is the main body of the fidget spinner, see... Figure 5 In this embodiment, the bottom plate of the body 2 is disc-shaped, and the edge of the bottom plate of the body 2 is provided with a plurality of regularly spaced blade connecting grooves 21. In this embodiment, the blade connecting groove 21 is a double T-shaped overlapping groove with two horizontal sides, opening outward and upward. That is, the two T-shaped grooves share a groove part facing outward from the circumference of the body 2. The horizontal side is a radial limiting structure 211. In this embodiment, there are 4 blade connecting grooves 21 distributed in a cross shape. The upper edge of the bottom surface of the body 2 is provided with a blade limiting part 22. The blade limiting part 22 is provided with internal threads and is connected to the middle of two adjacent blade connecting grooves 21. In this embodiment, the blade limiting part 22 is annular. The center of the body 2 is provided with a bearing hole that runs vertically through the body.

[0018] Still see Figures 1 to 4The blade 1 is detachably mounted on the body 2. The inner end of the blade 1 is provided with a mounting portion 11. In this embodiment, the mounting portion 11 corresponds to the largest T-shaped groove of the blade connecting groove 21 (i.e., the T-shaped groove corresponding to the inner ring side transverse edge) and is T-shaped. More preferably, the inner edge of the blade 1's main body is set to an arc shape corresponding to the bottom plate of the body 2. In other embodiments, the blade connecting groove 21 can also be configured as a multi-T-shaped overlapping groove with a radial limiting structure 211 of greater than or equal to two. That is, multiple T-shaped grooves share a groove portion facing outwards from the circumference of the body 2. Through multiple radial limiting structures 211 distributed sequentially from the inside out, each having T-shaped grooves of different lengths in the radial direction of the body 2, the body 2 forms T-shaped groove rings of different diameters. In other words, all blade connecting grooves 21 form T-shaped groove rings at the same radial position.

[0019] Bearing 3 is a fidget spinner bearing, its size corresponds to the bearing hole of body 2, and its thickness corresponds to the base plate of body 2. Bearing 3 has a central through hole.

[0020] The locking mechanism 4 uses a fidget spinner locking system. The locking mechanism 4 includes an upper locking mechanism 41 and a lower locking mechanism 42 that are detachable and connected from front to back. The size of the cover plate of the locking mechanism 4 corresponds to the bottom plate of the main body 2.

[0021] The blade limiting disc 5 is used to limit the forward and backward movement of the blade 1 from the front to the rear. In this embodiment, the blade limiting disc 5 is annular, and the size of the blade limiting disc 5 corresponds to the blade limiting part 22. The rear end face of the blade limiting disc 5 is provided with a neck, and the neck is provided with an external thread corresponding to the internal thread of the blade limiting part 22. The front end face of the blade limiting disc 5 is provided with a bayonet 51 for rotating installation or removal.

[0022] In this embodiment, the blade 1, the body 2, and the blade limiting disk 5 are all made of metal materials, such as stainless steel, titanium alloy, zirconium alloy, tungsten alloy, etc.

[0023] See Figure 6 The bearing 3 is inserted into the bearing hole of the body 2 through an interference fit. All blades 1 are inserted from their mounting part 11 into the corresponding T-slot rings of the blade connecting groove 21 of the body 2. Only the upper and lower blades 1 are shown in the figure. The blade limiting plate 5 is screwed into the blade limiting part 22 of the body 2 from the front through the bayonet 51 to limit the front and rear of the blades 1. The lower locking plate 42 of the locking plate 4 passes through the center of the bearing 3 and is tightly connected to the upper locking plate 41 to close the body 2, thus completing the assembly of the split fidget spinner. At this time, when the user pinches both sides of the locking plate 4 and moves the blades 1, the spinner rotates.

[0024] See Figure 5Since the blade connecting groove 21 is a double-T-shaped overlapping groove with two radial limiting structures 211 that opens outward and upward, meaning the two T-shaped grooves share a groove portion facing outward around the body 2, the user can insert the blade 1 into the corresponding T-shaped groove layer of the blade connecting groove 21. Different radial limiting structures 211 provide radial restraint for the blade 1, allowing for the creation of a split-type fidget spinner with a suitable diameter to fit the size of a hand. When used by a different user, the size can be easily adjusted according to the user's hand size. In other embodiments, more than two radial limiting structures 211 can be provided to achieve a more precise adjustment capability for the spinner diameter. Thus, when using blades of the same specification, the overall diameter of the spinner can be adjusted by selectively inserting the mounting part 11 of the blade 1 into the corresponding T-shaped groove layer of the blade connecting groove 21, thereby adjusting the length of the mounting part 11 exposed above the body 2.

[0025] Obviously, the above embodiments are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, these obvious variations or modifications derived from the spirit of the present invention are still within the scope of protection of the present invention.
