DETAILED DESCRIPTION

[0020] Please refer to Figures 1-7The utility model relates to a detachable wheel set, including rivet axle 5, wheel shell 1, support 2, limiting piece 3, wheel 4, rivet axle 5 passes through wheel shell 1, support 2, and will wheel shell 1, support 2 fixed as an organic whole, wheel 4 is through the bearing movable assembly in support 2 both sides, be provided with the axle hole 21 of assembling with rivet axle 5 in support 2 and be located the limiting slot 22 of axle hole 21 periphery, the outside wall of rivet axle 5 is provided with a circle carding groove 51, limiting piece 3 is assembled in limiting slot 22, while limiting piece 3 is carded in carding groove 51 and limit rivet axle 5 along its axial movement.

[0021] Rivet axle 5 passes through the axle hole 21 of wheel shell 1 and support 2, and a circle of carding grooves 51 is provided on the outer side wall thereof. Support 2 is provided with an axle hole 21 assembled with rivet axle 5 and a limiting slot 22 located at the periphery of the axle hole 21. When rivet axle 5 passes through the axle hole 21, limiting piece 3 is placed in limiting slot 22 and simultaneously carded in the carding groove 51 of rivet axle 5. Through this carding and fitting mode, limiting piece 3 can prevent the movement of rivet axle 5 in the axial direction, thereby enhancing the connection strength between wheel shell 1 and support 2. Even if the luggage is impacted by external force or jolted, this design can ensure that the wheel set remains stable and will not automatically fall off or get stuck. When it is necessary to disassemble or install the wheel set, it is only necessary to slightly adjust the position of limiting piece 3 so that it is no longer carded in the carding groove 51 of rivet axle 5, and the disassembly or installation can be easily completed, thereby simplifying the operation process.

[0022] Moreover, when the wheels 4 or wheel supports 2 of the luggage are damaged, the user does not need to send the entire luggage to a professional repair shop, but only needs to simply remove the limiting piece 3, disassemble the damaged wheel support 2 assembly, replace it with a new assembly, and reinsert the limiting piece 3, thereby completing the repair. This design greatly simplifies the repair process, saving the user's time and cost.

[0023] Meanwhile, the detachable structure allows users to replace wheels 4 of different colors, shapes, or functions according to their preferences and needs. This design meets the individualization requirements of users, making the luggage more personalized and fashionable. At the same time, users can also replace wheels 4 of different styles according to changes in occasions or seasons, making the luggage more practical and versatile.

[0024] In addition, there is another advantage that during transportation, the disassembled wheels 4 and wheel support 2 assemblies can significantly reduce the overall height of the luggage, thereby reducing the packaging volume. This not only reduces transportation costs but also helps to improve transportation efficiency. For manufacturers and logistics companies, this means lower transportation costs and higher logistics efficiency. For consumers, they can choose whether to purchase additional wheels 4 or wheel support 2 assemblies when purchasing, in order to adjust the functionality and appearance of the luggage according to actual needs.

[0025] Further discuss the specific scheme, the limiting part 3 includes a limiting part, the overall limiting part is a U-shaped structure, wherein the limiting part includes two vertical parts 31 placed vertically and a horizontal part 32 connected between the two vertical parts 31, and the two vertical parts 31 are respectively clamped in the clamping groove 51. The two vertical parts 31 of the limiting part are used to clamp in the clamping groove 51 of the outer side wall of the rivet shaft 5. The size and shape of the two vertical parts 31 match the clamping groove 51, ensuring that they can be tightly clamped therein. The horizontal part 32 connects the two vertical parts 31, providing stable structural support. When the rivet shaft 5 passes through the shaft hole 21 of the wheel shell 1 and the bracket 2, the two vertical parts 31 of the limiting part will naturally clamp into the clamping groove 51 of the rivet shaft 5. This clamping fit can prevent the rivet shaft 5 from moving in the axial direction, ensuring the stability of the wheel set structure.

[0026] However, it should be noted that the shape of the limiting part described above is a U-shaped structure, which is a preferred scheme for achieving the technical effect of the present application, but does not represent a limitation on the shape of the limiting part in this case. Therefore, in order to achieve the function of "clamping in the clamping groove 51 and limiting the axial movement of the rivet shaft 5", the limiting part can also be a V-shaped structure (not shown in the figure), such as a V-shaped structure limiting part mainly composed of two inwardly inclined side walls (i.e. two arms of the V-shaped structure) and a bottom platform connecting the two arms. This structure design makes the V-shaped structure have a natural clamping feature, which can tightly embed into the clamping groove 51 of the rivet shaft 5 while also preventing the rivet shaft 5 from moving in the axial direction.

[0027] Further discuss the specific scheme, the limiting part 3 also includes a limiting exposed part 33, which is integrally formed at the bottom of the horizontal part 32, and the outer side wall of the bracket 2 is also provided with a positioning groove 23 communicating with the limiting groove 22, the two vertical parts 31 are respectively clamped in the clamping groove 51, and the limiting exposed part 33 is fitted in the positioning groove 23. Further discuss the specific scheme, a disassembly gap 34 is reserved between the limiting exposed part 33 and the positioning groove 23. Further discuss the specific scheme, we introduce the disassembly gap 34 in the design of the limiting part 3 and the bracket 2. This gap allows the use of a flathead screwdriver-like tool to easily pry between the limiting exposed part 33 and the bracket 2, thereby quickly removing the entire limiting part 3, so that the whole is easily separated from the shell. This design greatly improves the convenience of disassembling and assembling the wheel set, while not affecting the stability and safety during normal use.

[0028] Further discussing the specific scheme, the two sides of the bracket 2 are provided with a card hole 27 communicated with the limiting groove 22, and the outer sides of the two vertical parts 31 are provided with a buckle protrusion 311, and the two vertical parts 31 are clamped in the card hole 27 through the buckle protrusion 311 to realize the assembly. Further discussing the specific scheme, we make the following improvements to the bracket 2 and the limiting part 3 of the wheel set: a card hole 27 communicated with the limiting groove 22 is opened on the two sides of the bracket 2. At the same time, a buckle protrusion 311 is protruded on the outer side of the two vertical parts 31 of the limiting part. The two vertical parts 31 are clamped in the card hole 27 of the bracket 2 through the buckle protrusion 311 to realize the stable assembly with the bracket 2. This design not only enhances the connection strength between the limiting part 3 and the bracket 2, making the wheel set more stable when subjected to external force and not easy to fall off or get stuck; but also simplifies the installation and disassembly process. When installing, you only need to align the vertical part 31 of the limiting part 3 with the card hole 27 of the bracket 2, and then press gently, so that the buckle protrusion 311 is clamped into the card hole 27 to complete the installation. When disassembling, you only need to exert a little force to make the buckle protrusion 311 come out of the card hole 27, thereby realizing quick disassembly. The cooperation design of the buckle protrusion 311 and the card hole 27 not only improves the stability and safety of the wheel set, but also improves the user experience.

[0029] Further discussing the specific scheme, the bottom of the bracket 2 is integrally formed with a plurality of elastic support strips 24, and the ends of the elastic support strips 24 are connected with an assembly part 26, and the bearing is embedded in the assembly part 26, and the adjacent elastic support strips 24 form a hollow hole 25.

[0030] On the basis of the previous design, we further optimize the bottom structure of the bracket 2, which realizes elastic deformation by utilizing its own hollow structure, thereby playing a role in shock absorption. At the same time, this hollow design indeed helps to reduce the overall weight of the bracket 2.

[0031] Specifically, the hollow hole 25 at the bottom of the bracket 2 has a certain elastic deformation ability. When the luggage encounters uneven road surface or is subjected to impact during movement, these hollow holes 25 will undergo slight elastic deformation, thereby effectively absorbing and dispersing the impact force, providing protection for the luggage and the items inside. This shock absorption not only prolongs the service life of the luggage, but also improves the user experience. In addition to the shock absorption effect, the hollow hole 25 also significantly reduces the overall weight of the bracket 2. Compared with the solid structure, the hollow hole 25 reduces the use of unnecessary materials while maintaining sufficient strength, making the bracket 2 more lightweight. This not only makes the luggage as a whole more portable and easy to operate, but also reduces the manufacturing cost and improves the cost performance of the product.

[0032] Further discuss the specific scheme, the rivet shaft 5's bottom and the outside surface are coated with the lubricating grease, can reduce the cooperation between the rivet shaft 5 and the axle hole 21 between the surface between friction.For the cooperation between the rivet shaft 5 and the axle hole 21, coating lubricating grease can form a layer of lubricating film, this layer of lubricating film can effectively isolate the metal surface, reduce the direct contact between them, thereby reducing the friction coefficient.

[0033] The above embodiments only describe the preferred embodiments of the present application, and do not limit the scope of the present application. Without departing from the design spirit of the present application, various modifications and improvements to the technical solutions of the present application made by ordinary engineering technicians in the art shall fall within the protection scope determined by the claims of the present application.
