Description

Technical Field

[0001] This utility model relates to the field of spinning toy technology, and more particularly to a spark spinning toy. Background Technology

[0002] Spinning wheels are a common type of toy. Their working principle primarily involves manually pulling a rope, tightening or loosening it to create a loop or uncoil, thus providing the initial power source for the wheel's rotation. They are simple to manufacture and inexpensive. To enhance the fun of these toys, some innovative designs have been developed. For example, the rope-pulling spinning wheel toy disclosed in announcement number CN206152322U uses a rope assembly to drive a spinning wheel assembly. After the assembly rotates at high speed, the engagement of a latch and a latching slot allows the rope assembly to detach from the wheel assembly, enabling the wheel to roll forward or backward. While rolling, the built-in light emits flashing lights, increasing playability and fun. However, this spinning wheel toy requires frequent searching for the rolled-off wheel assembly during play, which is inconvenient. Furthermore, its electrically powered light-emitting structure is prone to malfunctions due to poor contact, resulting in a high failure rate and difficulty in maintenance. Utility Model Content

[0003] The purpose of this invention is to provide a spark wheel toy to solve the problems mentioned in the background art, such as the inconvenience of using existing spark wheel toys, the high failure rate, and the difficulty in maintenance.

[0004] To achieve the above objectives, this utility model provides a spark wheel toy, including a wheel and a pull cord. The wheel includes a first wheel and a second wheel, which are rotatably connected by a rolling bearing. A cord-passing hole is provided through both the first and second wheels. A friction part is provided on one side of the first wheel opposite to the second wheel. The friction part is annular in shape with the same axis of rotation as the first wheel, or the friction part includes at least an arc-shaped segment with the same axis of rotation as the first wheel. The second wheel has at least one mounting groove directly opposite the friction part. A flint is detachably connected to the mounting groove, and the flint contacts and connects with the friction part, generating sparks through friction. The pull cord passes sequentially through the cord-passing hole connecting the first and second wheels.

[0005] As a preferred embodiment, the first wheel includes a first wheel body and a fixing member. The first wheel body is provided with a connecting groove and the friction part on the same side. One end of the fixing member passes through the connecting groove and is detachably fixedly connected to the second wheel. The groove wall of the connecting groove and the second wheel are connected by the rolling bearing.

[0006] As a preferred embodiment, the outer side wall of the first wheel body is provided with a connecting hole extending through it toward the bottom wall of the connecting groove. The connecting hole is used to allow one end of the fixing member to pass through and extend into the connecting groove. The other end of the fixing member has a flange that can abut against and connect to the outer side wall of the first wheel body.

[0007] As a preferred embodiment, the second rotating wheel is provided with a connecting block extending in the same direction as the flint. The connecting block is detachably fixed to the fixing member, and the two are provided with the rope threading hole in a one-to-one correspondence. The connecting block is fitted with the rolling bearing and connected to the connecting groove through the rolling bearing.

[0008] As a preferred embodiment, the connecting block and the fixing member are detachably connected by a threaded component. The connecting block and the fixing member are respectively provided with threaded holes and countersunk holes. When the countersunk holes are distributed on the connecting block or the fixing member, a through hole is provided on the outer wall of the second rotating wheel or the outer wall of the fixing member to connect the countersunk holes and the rope threading holes to the outside.

[0009] As a preferred embodiment, the flint is movably connected within the mounting groove, and the flint is connected to the groove wall of the mounting groove via an elastic element, which is used to drive the flint to a position where it contacts and connects with the friction part.

[0010] As a preferred embodiment, the friction part is one or more of the following: a rough friction surface, a friction plate, and sandpaper.

[0011] As a preferred embodiment, the second wheel includes a second wheel body and a closure. The second wheel body is provided with the mounting groove, and the closure covers and is connected to the outside of the mounting groove and is detachably connected to the second wheel body. The closure has a locking block protruding into the mounting groove for positioning the elastic element.

[0012] As a preferred embodiment, the second wheel body includes a third housing and a fourth housing, which are detachably fixed together by an interlocking structure, and the third housing and the closure are detachably fixed together by a threaded component.

[0013] As a preferred embodiment, the number of pull ropes is at least two, with each pull rope passing through and connected to one of the multiple rope holes, and the pull ropes at the same end being connected and fixed to the same pull ring.

[0014] Therefore, based on the technical means of this utility model, the effects that this utility model can achieve are briefly described as follows: The spark wheel toy provided by this utility model includes a first wheel and a second wheel rotatably connected by rolling bearings. Friction parts and at least one flint are separately provided on opposite sides of the first wheel and the second wheel. The flint contacts and connects with the friction parts, generating sparks through friction. Therefore, when the player drives the first wheel and the second wheel to rotate by pulling a rope, relative rotation occurs between the first wheel and the second wheel due to differences in the direction and magnitude of the force applied, resulting in visible sparks flying between the first wheel and the second wheel during the game. Compared with existing structures, the spark wheel toy provided by this utility model is simple and convenient to use. It generates sparks through mechanical friction, which increases the fun while enhancing structural stability and reducing the toy's failure rate. Furthermore, the flint is detachably connected in the mounting slot, facilitating maintenance and replacement, making it convenient and quick to operate, and offering higher operability.

[0027] Please refer to Figures 1 to 5 This embodiment provides a spark wheel toy, including a spinning wheel 100 and a pull rope 200. The spinning wheel 100 has at least two rope holes 1001 extending through both sides. The pull rope 200 includes at least two strands of rope, the same number as the rope holes 1001. These multiple strands of rope pass through the multiple rope holes 1001 and are located at the same end, then are connected and fixed to the same pull ring 300. During gameplay, the player can control the multiple strands of rope to twist into one using the pull ring 300, and then manually pull the pull rope 200 to tighten or loosen it, thus causing the spinning wheel 100 to rotate.

[0028] It is understood that the rotating wheel 100 includes a first rotating wheel 110 and a second rotating wheel 120 that are rotatably connected. Both the first rotating wheel 110 and the second rotating wheel 120 have at least two through holes 1001. It should be noted that when the rotating wheel 100 rotates, the first rotating wheel 110 and the second rotating wheel 120 can rotate relative to each other due to differences in the direction and magnitude of the forces applied. The first rotating wheel 110 and the second rotating wheel 120 are rotatably connected by a rolling bearing 130. The rolling bearing 130 reduces friction during power transmission and improves the efficiency of mechanical power transmission, making the relative rotation of the first rotating wheel 110 and the second rotating wheel 120 smoother and more fluid. This improves rotation efficiency, increases rotation time to prolong the spark effect, and enhances the user experience.

[0029] In this embodiment, the first rotating wheel 110 includes a first wheel body 111 and a fixing member 112. The first wheel body 111 is formed by detachably fixed first housing 1101 and second housing 1102, which are detachably connected using screws or other threaded components. The outer surface of the first housing 1101 is planar. On the same side of the planar structure, the first wheel body 111 has a connecting groove 1111 and a friction part 1112, located on the side of the first wheel body 111 opposite to the second rotating wheel 120. The connecting groove 1111 is used to install a rolling bearing 130, and the friction part 1112 is used to cooperate with a flint 140 mounted on the second rotating wheel 120 to generate sparks through friction, enhancing the game's enjoyment. It is understood that the friction part 1112 can be one or more of a rough friction surface, a friction plate, or sandpaper to ensure that the friction part 1112 can generate sparks through friction with the flint 140 during rotation. Specifically, the connecting groove 1111 is configured corresponding to the axis of rotation of the first wheel body 111. In this embodiment, a friction part 1112 in a continuous annular shape is provided on the outer periphery of the connecting groove 1111. The axis of rotation of the friction part 1112 coincides with the axis of rotation of the first wheel body 111 (i.e., the friction part 112 and the first wheel 110 are configured with the same axis of rotation), so that the friction part 1112 can also rotate around the axis of rotation. The above design is used to ensure that the friction part 1112 can maintain continuous and uninterrupted contact with the flint 140, ensuring that sparks can be continuously generated during rotation. In other embodiments of this utility model, the first wheel 110 may only include the first wheel body 111. In this case, the first wheel body 111 can be connected to the second wheel 120 by fastening it to the rolling bearing 130. The first housing 1101 and the second housing 1102 can be connected by other means, such as snap-fit ​​connection, plug-in connection, ultrasonic welding, etc. Meanwhile, the friction part 1112 can also adopt a non-annular shape. In this case, the friction part 1112 includes at least an arc-shaped segment that rotates on the same axis as the first rotating wheel 110. That is, at least one friction part 1112 with an arc-shaped segment is distributed on the outside of the connecting groove 1111. It is used to generate sparks when the friction part 1112 rotates to contact the flint 140, so as to achieve the purpose of intermittently generating sparks.

[0030] A connecting hole 1113 is provided on the outer side wall of the first wheel body 111, extending through the bottom wall of the connecting groove 1111. The connecting hole 1113 allows one end of the fixing member 112 to pass through and extend into the connecting groove 1111, so that the fixing member 112 can be fixedly connected to the second rotating wheel 120. The other end of the fixing member 112 has a flange 1121. When one end of the fixing member 112 enters the connecting groove 1111 and is fixedly connected to the second rotating wheel 120, the flange 1121 can abut against the outer side wall of the first wheel body 111, thereby achieving the purpose of fixing the first wheel body 111 to the second rotating wheel 120. It is understandable that, since the first rotating wheel 110 is fixedly connected to the second rotating wheel 120 via the fixing member 112, and since the rolling bearing 130 is disposed between the first wheel body 111 and the second rotating wheel 120, when not playing the pull-string spinning game, players can also choose to play a finger spinning game. That is, players can press two fingers on the flange 1121 and the second rotating wheel 120, and then flick the first wheel body 111 to make it rotate at high speed to play a finger spinning game. The above-mentioned configuration can increase the versatility of the spinning toy and enhance its attractiveness. In this embodiment, the fixing member 112 and the second rotating wheel 120 are detachably connected by a screw or other threaded component. At this time, the fixing member 112 is provided with a threaded hole 1122 for connecting the threaded component. In other embodiments of this utility model, the fixing member 112 and the second rotating wheel 120 can be detachably connected by other means, such as a snap-fit ​​connection, a plug-in connection, a magnetic connection, etc.

[0031] In this embodiment, the second wheel 120 includes a second wheel body 1201 and a closure 1202. At least one mounting groove 1213 is provided through the second wheel body 1201, and a flint 140 is detachably connected to the mounting groove 1213. To increase the ease of installation and removal of the flint 140, the closure 1202 is connected to the outside of the mounting groove 1213 and detachably connected to the second wheel body 1201. When only the flint 140 needs to be replaced, the player can quickly open or close the mounting groove 1213 by simply removing or installing the closure 1202 on the second wheel body 1201, effectively saving maintenance steps and time and improving ease of use. In other embodiments of this utility model, the second rotating wheel 120 may only include the second wheel body 1201. In this case, the mounting groove 1213 may still be a through groove structure (in this case, the groove opening of the mounting groove 1213 may be provided with a structure that functions to open and close the groove opening, such as a plug). The mounting groove 1213 may also be a groove structure with a closed bottom. In this case, the flint 140 and the friction part 1112 can be replaced and maintained by disassembling and assembling the first rotating wheel 110 and the second rotating wheel 120.

[0032] The second wheel body 1201 includes a detachably fixed third housing 121 and a fourth housing 122. The outer surface of the third housing 121 is also a planar structure, and a connecting block 1211 connected to one end of the fixing member 112 is provided on the planar structure. In this embodiment, the connecting block 1211 is provided with a countersunk hole 1212 for connecting the threaded member, and the connecting block 1211 and the fixing member 112 are detachably connected through the threaded member. It can be understood that a rolling bearing 130 is sleeved on the connecting block 1211 and connected to the connecting groove 1111 through the rolling bearing 130, and a rope hole 1001 is provided on the connecting block 1211 and the fixing member 112 respectively. Since the connecting block 1211 is provided with a countersunk hole 1212, a through hole 1222 is opened on the outer wall of the second wheel 120 (i.e., on the fourth housing 122 and the sealing member 1202) to connect the countersunk hole 1212 and the rope hole 1001 to the outside, so as to achieve a compact structure and a more reasonable spatial distribution. In other embodiments of this utility model, the connection structure on the connecting block 1211 can be adaptively adjusted according to the different connection methods adopted between it and the fixing member 112. When the fixing member 112 is provided with a countersunk hole and the connecting block 1211 is provided with a threaded hole, the through hole 1222 is opened on the outer wall of the fixing member 112.

[0033] In this embodiment, to facilitate the fixing of the third housing 121 and the fourth housing 122, the third housing 121 and the fourth housing 122 are detachably fixed through an interlocking structure. The third housing 121 has mounting grooves 1213 extending through the closure member 1202. Multiple flints 140 are installed in the mounting grooves 1213, ensuring that at least one flint 140 is located on the side of the second rotating wheel 120 opposite to the friction part 1112. In this case, the flint 140 extends in the same direction as the connecting block 1211. The third housing 121 also has slots 1214 and threaded grooves 1215. The slots 1214 are used to insert the posts 1221 of the fourth housing 122, allowing the fourth housing 122 to be securely connected to the third housing 121. The threaded groove 1215 corresponds to the fixing hole 1231 of the closure 1202. That is, the fixing hole 1231 passes through the fourth housing 122 and connects with the threaded groove 1215, so that screws and other threaded parts can be fixedly connected in the fixing hole 1231 and the threaded groove 1215. This allows the third housing 121 and the closure 1202 to be detachably fixed through the threaded parts, and also serves to further fix the third housing 121 and the fourth housing 122. In this embodiment, the flint 140 is movably connected to the mounting groove 1213 through the elastic element 150. Therefore, the closure 1202 has a locking block 1232 protruding into the mounting groove 1213 for positioning the elastic element 150. The elastic element 150 is used to drive the flint 140 to move to the position of contacting and connecting with the friction part 1112, so that the flint 140 can maintain continuous contact with the friction part 1112. In other embodiments of this utility model, if the second rotating wheel 120 does not have a sealing member 1202 and the mounting groove 1213 is a bottom-closed groove structure, then a corresponding locking block for positioning the elastic member 150 can be provided on the bottom wall of the groove structure. In other embodiments of this utility model, the connection between the third housing 121 and the fourth housing 122, and between the third housing 121 and the sealing member 1202, can be other common fixing methods such as snap-fit ​​connection. In other embodiments of this utility model, the flint 140 can be tightly fitted into the mounting groove 1213. Using this method, the connection position of the flint 140 in the mounting groove 1213 needs to be adjusted after a period of use to prevent the flint 140 from separating from the friction part 1112 due to wear.

[0034] For clarity, certain features described in individual embodiments of the present invention may be used in combination in a single embodiment. Furthermore, various features of the present invention described in individual embodiments may also be used individually or in any suitable form in sub-combinations.
