Abstract
Description
Technical Field
[0001] This utility model relates to the field of toys, specifically to a toy wheel with a reliable structure. Background Technology
[0002] Existing toy wheels that use several inclined rollers to support rotation and adjust steering typically have decorative parts attached to the wheel shell after the outer shell, inner shell, and rollers are assembled, then snapped on from the outside in. However, this method of installation results in a structurally unreliable toy wheel. The decorative parts are prone to detachment; during use, a collision may cause them to fall off, and they can easily be pried off manually from the outside, making them unsafe to use. Summary of the Invention
[0003] The purpose of this invention is to address the aforementioned problems and deficiencies by providing a toy wheel that is more reliable in structure and safer in use.
[0004] The technical solution of this utility model is implemented as follows:
[0005] The toy wheel with a reliable structure according to this utility model is characterized by comprising a wheel shell, a wheel decoration, a wheel inner shell, and several rollers. First, the wheel decoration is inserted into the wheel shell from the inside to the outside of the wheel. Then, one end of each roller is movably installed onto the wheel shell, while the wheel inner shell is connected to the wheel shell so that the other end of each roller is movably installed onto the wheel inner shell. At this time, several rollers are respectively inclined and equally spaced around the wheel shell and the wheel inner shell to realize the rotation support and steering adjustment of the wheel. The wheel decoration is pressed and fixed onto the wheel shell by the wheel inner shell.
[0006] To make the structure of this utility model novel and the connection more reliable, the outer side of the circular seat of the wheel decoration part is provided with an inner decorative ring and an outer decorative ring, and a groove is formed between the inner decorative ring and the outer decorative ring. The wheel shell is provided with an inner ring through hole and an outer ring through hole at the corresponding positions of the inner and outer decorative rings. A stop block is formed between the inner ring through hole and the outer ring through hole for connecting with the groove. The wheel decoration part is installed on the wheel shell from the inside to the outside by correspondingly inserting the inner decorative ring and the outer decorative ring into the inner ring through hole and the outer ring through hole.
[0007] To make the appearance of this utility model more aesthetically pleasing and easy and reliable to install, the inner decorative ring and the outer decorative ring are each composed of a number of equally spaced decorative blocks, and the inner ring through hole and the outer ring through hole are each composed of a number of equally spaced through holes, and the number of through holes is the same as the number of decorative blocks.
[0008] To facilitate the fixing of the wheel decoration, several positioning plates are evenly spaced around the inner side of the circular base of the wheel decoration. The positioning plates abut against the inner ring of the inner shell of the wheel, thereby pressing and fixing the wheel decoration to the outer shell of the wheel by the inner shell of the wheel.
[0009] To ensure convenient and reliable fixing of the overall structure of this utility model, a number of screw connecting posts are provided at equal intervals on the inner side of the wheel shell. The screw connecting posts pass through the wheel decoration and are connected to the inner shell of the wheel.
[0010] To ensure reliable connection and smooth rotation of the rollers, several limiting plates are provided at equal intervals on the inner side of the wheel shell. The limiting plates abut against the inner ring of the wheel inner shell, thereby creating a space between the wheel shell and the wheel inner shell for the rollers to be reliably connected to the wheel shell and the wheel inner shell.
[0011] To facilitate the manufacture and installation of this utility model, it also includes a wheel axle connector, which is inserted from the inside of the wheel to the outside of the wheel into the inner shell of the wheel and fixedly connected to the inner shell and the outer shell of the wheel with screws.
[0012] To make the wheel decoration more secure, the inner end of the axle connection of the wheel axle connector is inserted into the axle hole set in the center of the wheel decoration.
[0013] Compared with the prior art, this utility model has the following advantages:
[0014] This invention employs a structure where the wheel trim is first installed onto the wheel shell from the inside out, followed by the installation of other wheel components. The wheel shell and inner shell press and fix the trim between them, making the overall wheel structure more reliable. This prevents the trim from detaching due to collisions or being manually pried off, effectively ensuring the wheel's safety and reliability. Furthermore, this structure results in a smoother overall surface, eliminating the risk of children getting scratched by rough wheel surfaces during play, further enhancing safety. In addition, this invention is aesthetically pleasing, compact in structure, and easy to manufacture and install.
[0015] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

[0020] like Figures 1-4 As shown, the toy wheel with a reliable structure according to this utility model includes a wheel outer shell 1, a wheel decorative piece 2, a wheel inner shell 4, and several rollers 3. The wheel outer shell 1, wheel decorative piece 2, and wheel inner shell 4 are all configured as annular structures, and the maximum outer diameter of the wheel outer shell 1 and the wheel inner shell 4 are the same. During installation, the wheel decorative piece 2 is first inserted into the wheel outer shell 1 from the inside of the wheel to the outside of the wheel (the inside and outside of the wheel referred to in this utility model are as follows...). Figure 1 (Indicated by the markings), while movably mounting one end of each roller 3 onto the wheel outer shell 1, the wheel inner shell 4 is connected to the wheel outer shell 1 so that the other end of each roller 3 is movably mounted onto the wheel inner shell 4. After the wheel is assembled, the centers of the wheel outer shell 1, the wheel trim 2, and the wheel inner shell 4 are all located on the same axis of the wheel, and as shown... Figure 1 and Figure 2 As shown, the wheel outer shell 1 and the wheel inner shell 4 are arranged side by side, and a plurality of screw connecting posts 14 are evenly spaced around the wheel axis on the inner side of the wheel outer shell 1. The screw connecting posts 14 pass through the wheel trim 2 and connect to the wheel inner shell 4. In this embodiment, a total of four screw connecting posts 14 are provided, and they are integrally formed with the wheel outer shell 1. In addition, the screw connecting posts 14 can also be provided in the form of three, five, etc., depending on the actual situation. Figure 1 As shown, the overall surface of this toy wheel is also more smoothly designed.
[0021] At this time, several rollers 3 are inclined and equally spaced around the wheel outer shell 1 and the wheel inner shell 4 to provide rotational support and steering adjustment for the wheel. In other words, the wheel outer shell 1 and the wheel inner shell 4 only serve to support the rollers 3. During rotation, the toy car moves by the contact between each roller 3 and the driving surface. In this embodiment, a total of eight rollers 3 are provided, arranged equally spaced around the wheel axis, and each roller 3 has the same inclination angle. Specifically, each roller 3 consists of a rotating shaft 31 and a tire 32 fitted onto the rotating shaft 31. Both ends of the rotating shaft 31 extend a certain distance beyond the tire 32, allowing the rotating shaft 31 to be rotatably connected to the wheel outer shell 1 and the wheel inner shell 4. At this time, the same number of outer shell connecting holes 16 and inner shell connecting holes 42 as the number of rollers 3 are opened on the two opposite surfaces of the wheel outer shell 1 and the wheel inner shell 4. The positions of the outer shell connecting holes 16 and the inner shell connecting holes 42 are staggered and are arranged in a ring around the wheel axis at equal intervals, so that each roller 3 can be arranged at equal intervals between the wheel outer shell 1 and the wheel inner shell 4 at the same tilt angle. Meanwhile, each outer shell connection hole 16 and each inner shell connection hole 42 is designed with an flared structure that is smaller inside and larger outside. When one end of the rotating shaft 31 is installed on the outer shell connection hole 16 and the other end is installed on the inner shell connection hole 42, the roller 3 forms a movable connection on the wheel outer shell 1 and the wheel inner shell 4. Thus, when the toy car is operated, the roller 3 can both contact the driving surface to rotate and realize the movement of the toy car, and can also move freely within the range defined by the outer shell connection hole 16 and the inner shell connection hole 42 to ensure that the roller 3 can maintain contact with the driving surface on different driving surfaces. This effectively improves the stability of the toy car and prevents slippage. It also facilitates the steering adjustment of the toy car.
[0022] To ensure convenient and reliable fixing of the wheel trim 2, the wheel trim 2 is pressed and fixed to the wheel outer shell 1 by the inner wheel shell 4. Specifically, a plurality of inwardly extending positioning plates 25 are provided at equal intervals around the axis on the inner side of the circular seat 21 of the wheel trim 2. The wheel trim 2 is pressed and fixed to the wheel outer shell 1 by the inner wheel shell 4 through the inner ring 41 of the inner wheel shell 4 by the positioning plates 25 abutting against each other. In this embodiment, a total of eight positioning plates 25 are provided. In addition, the inner ring 41 of the inner wheel shell 4 is also provided with connecting seat holes 43 in the same number and corresponding positions as the screw connecting posts 14. To enhance the aesthetics of the wheel and ensure a more stable and reliable connection for the wheel trim 2, an inner decorative ring 22 and an outer decorative ring 23 are provided on the outer side of the circular base 21 of the wheel trim 2. A groove 24 is formed between the inner and outer decorative rings 22 and 23. An inner ring through hole 11 and an outer ring through hole 12 are provided on the wheel outer shell 1 at positions corresponding to the inner and outer decorative rings 22 and 23. A stop block 13 is formed between the inner and outer ring through holes 11 and 12 to engage with the groove 24, thus ensuring that the wheel trim 2 cannot be manually removed from the outside. In this embodiment, the inner decorative ring 22 and outer decorative ring 23 are each composed of eight decorative blocks spaced equally around an axis. The inner ring through hole 11 and outer ring through hole 12 are each composed of eight through holes spaced equally around an axis. Furthermore, each decorative block of the outer decorative ring 23 is configured as a polygonal structure, and each decorative block of the inner decorative ring 22 is configured as a stepped structure. During assembly, the wheel trim piece 2 is installed onto the wheel shell 1 from the inside out through the corresponding insertion of the inner trim ring 22, the outer trim ring 23 and the inner ring through hole 11, the outer ring through hole 12, and is limited by the slot 24 and the stop block 13. Moreover, the number of trim pieces can be set according to the actual situation, for example, it can be set to four pieces, six pieces, etc.
[0023] To ensure the rollers 3 can be reliably connected between the wheel outer shell 1 and the wheel inner shell 4 and rotate smoothly, a plurality of limiting plates 15 are provided at equal intervals around the inner side of the wheel outer shell 1 along its axis. These limiting plates 15 abut against the inner ring 41 of the wheel inner shell 4, creating a space between the wheel outer shell 1 and the wheel inner shell 4 for the rollers 3 to be reliably connected. In this embodiment, a total of eight limiting plates 15 are provided, and four of these limiting plates 15 are integrally connected with a screw connecting post 14. During installation, the limiting plates 15 on the wheel outer shell 1 pass through the wheel trim 2 and are staggered with the positioning plates 25 on the wheel trim 2, forming an interlocking structure that makes the wheel structure more compact.
[0024] To allow for diverse structural configurations, the inner wheel shell 4 and outer wheel shell 1 can be directly connected and fixed together using screws. In this case, a pivot connection portion can be integrally provided at the center of the inner wheel shell 4, thereby connecting the wheel to the toy car through the pivot connection portion and the wheel pivot. Alternatively, as in this embodiment, a separate circular wheel pivot connector 5 can be provided. During installation, the wheel pivot connector 5 is inserted from the inside of the wheel to the outside of the wheel into the inner wheel shell 4 and fixedly connected to the inner wheel shell 4 and outer wheel shell 1 together using screws. Specifically, the wheel axle connector 5 has an integrally formed axle connecting portion 51 extending towards the inner wheel shell 4 on its axle center. The axle connecting portion 51 has a hexagonal shaft hole 52 with an open outer end for fixed connection with the wheel axle. Simultaneously, screw connecting holes 53, the same number and position as the screw connecting posts 14, are equally spaced around the outer periphery of the axle connecting portion 51 on the wheel axle connector 5. When the axle connecting portion 51 passes through the center of the inner wheel shell 4, its inner end is inserted into the shaft hole 26 at the center of the wheel decoration 2, further pressing and positioning the wheel decoration 2. Furthermore, the screw passes through the screw connecting hole 53 and the connecting seat hole 43 and connects to the screw connecting post 14, thereby connecting the wheel axle connector 5, the inner wheel shell 4, the roller 3, the wheel decoration 2, and the outer wheel shell 1 into a single unit, forming the toy wheel described in this utility model, which has a reliable structure and is safer to use.
