[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] Referring to all the accompanying drawings, an adjustable planetary gear carrier includes:

[0022] The ring-shaped support base 11 is an existing structure with a connection point for connecting to the luggage wheels, such as a connection port or a connecting shaft. The inner ring of the support base 11 has several evenly distributed mounting openings 12, with at least three mounting openings 12. All mounting openings 12 are arc-shaped, with the center of the arc 12 coinciding with the center of the support base 11, allowing for symmetrical installation. This facilitates the manufacturing of this component and also facilitates the installation of other components. A baffle 13 is provided inside the mounting opening 12 and along its edge. Preferably, the baffle 13 forms a 90° angle with the support base 11. Screw holes 14 are provided on the baffle 13, located at the middle of the baffle 13.

[0023] A single planetary support 15 includes a first connecting plate 16. The first connecting plate 16 has arc-shaped ends that can fit into the mounting opening 12. Both ends of the first connecting plate 16 have first stabilizing plates 17 that match the baffle 13. The first stabilizing plates 17 are connected to first bolts 18 and matching nuts. The first bolts 18 are threadedly connected to the screw holes 14. The center end of the first connecting plate 16 has a connecting rod 19. One side of the outer surface of the connecting rod 19 has a protrusion 20. The end of the connecting rod 19 away from the first connecting plate 16 has a plug 21 with a polygonal cross-section. The plug 21 can be an equilateral polygon or an irregular polygon. The straight-line distance between the edge line with the smallest angle of the plug 21 and the center line of the plug 21 is less than the radius of the connecting rod 19, that is, the plug 21 is smaller than the connecting rod 19.

[0024] The plug 21 is fitted with a drive handle 22, which makes it easy to insert the drive handle 22 into the plug 21, facilitating both assembly and disassembly.

[0025] Multiple sets of planetary support brackets 23 include sleeves 24 that can be fitted onto the connecting rod 19. Each sleeve 24 has a hole 25 that matches a protrusion 20. The protrusion 20 is inserted into the hole 25 to limit the sleeve 24 and prevent it from rotating. Multiple sets of protrusions 20 and holes 25 can be configured. One end of the sleeve 24 has a second connecting plate 26. At least one end of the second connecting plate 26 has a structure that matches a baffle 13. The end of the second connecting plate 26 that matches the baffle 13 has a second stabilizing plate 27. The stabilizing plate 27 has a second bolt 28, which is threaded into a screw hole. The side of the second connecting plate 26 opposite to the sleeve 24 has a sun gear 29. The sun gear 29 is connected to the second connecting plate 26 via a gear shaft. There can be several sun gears 29; here, we will first illustrate with one sun gear 29.

[0026] As an embodiment of this utility model, in addition to the above structure, when there are four mounting ports 12, the mounting ports 12 are still evenly arranged on the bracket base 11; both ends of the second connecting plate 26 can be connected to any one of the baffles 13; both second stabilizing plates 27 have second bolts 28, and the second bolts 28 are threadedly connected to the corresponding screw holes 14.

[0027] In specific implementation of this utility model: if the drive handle structure and / or sun gear are not required, the original connection port or connecting shaft on the bracket base 11 can be directly used to connect with the planet gear;

[0028] When a drive handle structure is required, the two ends of the first connecting plate are snapped into the mounting port, then the baffle and the first stabilizing plate are aligned and locked using the first bolt. Then the drive handle is inserted into the plug of the connecting round rod to complete the single planetary gear support structure.

[0029] When the sun gear needs to be installed, the drive handle is removed from the single planetary gear support structure. Then, the sleeve hole inside the sleeve is fitted with the protrusion and placed on the connecting round rod. Then, the second stabilizing plate and the other baffle are connected by the second bolt thread to complete the multi-planetary gear support structure.

[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
