Description

Technical Field

[0001] This utility model relates to an internally supported assembled wheel, belonging to the technical field of wheels. Background Technology

[0002] Wheels were gradually discovered by humans in their labor practices of transporting goods. A wheel consists of an axle and a tire fitted onto the axle, and its main function is to support sliding. There are many types of wheels, and they are widely used; any device that can move close to the ground can be equipped with wheels.

[0003] Currently, mobile wheels with relatively small loads are generally used in mobile devices such as children's cars and toy cars with small loads. Since their loads are small, they are molded using injection-molded structural parts to meet the requirements of load, structural strength and cost control.

[0004] These types of wheels typically consist of injection-molded axles and tires. To facilitate assembly, they are often made of spliced ​​axles, secured with pins. This satisfies the assembly requirements of the axle and tire. However, the pin-locking structure of spliced ​​axles results in poor axial stability, making them prone to loosening and separation. Furthermore, spliced ​​axles have relatively poor stability within the tire, making them more susceptible to loosening, abnormal noises, and deviations in direction. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of the existing technology and to propose an internally supported wheel assembly method that addresses the difficulties and easy loosening of traditional wheel assembly operations.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An internally supported assembled wheel includes a tire and an axle.

A snap-locking mechanism is provided between the two limiting axles.

[0007] Preferably, an annular wall is provided between the limiting shaft and the transmission shaft tube of the splicing shaft; The buckle locking mechanism is disposed on the annular wall of the two splicing shafts, and the buckle locking mechanism includes a buckle groove and a locking buckle that cooperates with the buckle groove.

[0008] Preferably, the ring wall is provided with a plurality of locking buckles evenly distributed in the circumference, and a buckle groove is provided between any two adjacent locking buckles, and the buckle grooves of the two splicing shafts are matched with the locking buckles one by one.

[0009] Preferably, the ring wall is provided with circumferentially evenly distributed bosses, and the locking buckles are respectively provided on the platform of the bosses, and the ring walls of the two splicing shafts are mortise and tenon connected together.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0026] This utility model provides an internally supported assembled wheel, such as Figures 1 to 8 As shown, it includes a tire 1 and a wheel axle 2. The wheel axle 2 has a drive shaft tube 3 for connecting the drive shaft. The drive shaft is the power shaft that mounts and assembles the wheel in the prior art. It belongs to the prior art and generally adopts a structure that connects the drive shaft through the drive shaft tube 3 to meet the requirement that the wheel can rotate freely on the drive shaft. It will not be described in detail here.

[0027] In this case, if Figure 1 and Figure 3 As shown, the tire 1 includes an axle channel 11 for mounting the wheel axle. The two ends of the axle channel 11 are respectively provided with wide ends 12, and the cross section of the axle channel is an equilateral polygon.

[0028] The axle channel 11 is used for the axle 2 to pass through, while the wide end 12 is used to axially limit the two ends of the axle 2 to prevent axial movement. The equilateral polygon can be an equilateral triangle, square, equilateral pentagon, or equilateral hexagon. Any structure that satisfies the requirement of an equilateral polygon is within the protection scope of this case. Figure 3 The disclosed embodiment is an equilateral hexagon, which is the optimal solution. Any structure that satisfies the requirement of having an equilateral polygonal cross-section and circumferential limiting stability is within the protection scope of this case.

[0029] like Figures 3 to 8 As shown, the wheel axle 2 includes two detachably connected splicing shafts 4. The splicing shaft 4 includes a limiting disc 41 that is matched with the wide end for limiting, and a limiting shaft 42 that is matched with the shaft channel for limiting in the circumferential direction. A snap-locking mechanism 5 is provided between the two limiting shafts.

[0030] Detailed implementation process and principle explanation: The two splicing shafts 4 are identical structural components. During the splicing process, the limiting shafts 42 of the two splicing shafts 4 pass through the shaft channel, so that the limiting disc 41 and the wide end 12 are axially limited and abutted. At this time, the two limiting shafts 42 are locked and fixed in the shaft channel by the snap-locking mechanism 5.

[0031] This facilitates the splicing and assembly of the wheels, and after splicing and assembly, the wheels are securely and stably locked in both the circumferential and axial directions.

[0032] In one embodiment, an annular wall 6 is provided between the limiting shaft of the splicing shaft 4 and the transmission shaft tube, and a snap-locking mechanism is provided on the annular wall of the two splicing shafts. The snap-locking mechanism 5 includes a snap-locking groove 51 and a locking snap 52 that cooperates with the snap-locking groove.

[0033] Specifically, the ring wall 6 facilitates the mounting of the latching mechanism 5, and the latching groove 51 and the locking latch 52 achieve a locking engagement. At the same time, the relatively open end of the ring wall 6 is exposed, enabling disassembly.

[0034] In one specific embodiment, the annular wall 6 is provided with a plurality of locking buckles evenly distributed in the circumference, and a buckle groove is provided between any adjacent locking buckles. The buckle grooves of the two splicing shafts correspond one-to-one with the locking buckles.

[0035] Multiple circumferentially evenly fitted locking buckles and buckle grooves work together to ensure locking stability.

[0036] In a preferred embodiment, the annular wall 6 is provided with circumferentially evenly distributed bosses 60, and locking buckles are respectively provided on the platform of the bosses, and the annular wall of the two splicing shafts are mortise and tenon connected together.

[0037] This achieves the foolproof design of the two splicing shafts 4, which are circumferentially opposite to prevent foolproofing, while the tenon and mortise joint ensures the locking stability after assembly and the buckle is not easy to loosen.

[0038] In one specific embodiment, the equilateral polygon is provided with a limiting corner wall 110 formed by the edges, the limiting shaft 42 has a circular tube body 421, the circular tube body 421 is provided with a limiting part 422 corresponding to the limiting corner wall, and the limiting part includes at least one axially arranged limiting rib.

[0039] This makes the forming structure of the splicing shaft 4 simpler, while ensuring the strength of the limiting structure and the reliability of the mating.

[0040] In one specific embodiment, the limiting rib is connected to the limiting disc. The drive shaft tube is provided with a plurality of circumferentially evenly distributed radial ribs 30, which are respectively connected to the limiting disc, the limiting shaft, and the annular wall.

[0041] This satisfies the overall structural strength of wheel axle 2 and extends its effective service life.

[0042] In one specific embodiment, the splicing shaft is an integrally injection-molded structural component.

[0043] One-piece injection molding meets the needs of mass injection production, and its cost is effectively controlled.

[0044] As described above, this utility model provides an internally supported assembled wheel that meets the axial and circumferential locking stability requirements of wheel assembly, making wheel assembly more efficient and convenient. It features axial locking and circumferential limiting locking structures, ensuring reliable stability during wheel use, while also providing reliable structural strength and effectively extending service life. It facilitates mass production via injection molding, reducing production and assembly costs and enhancing market competitiveness.

[0045] The term "comprising" or any other similar term is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus / device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent in such process, method, article, or apparatus / device.

[0046] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
