DETAILED DESCRIPTION

[0026] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0027] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0028] Figure 1-Figure 6 As shown, a high-strength wheel hub that is easy to disassemble includes a wheel hub body 1 and a center disk 2 arranged at the center of the wheel hub body 1, a rotating disk 3 is detachably connected to the center disk 2, a plurality of fixed plates 11 are hinged at the free end of the rotating disk 3 through a pin shaft 12, the pin shaft 12 is staggered with the longitudinal center axis of the fixed plate 11, a slot 9 is provided on the center disk 2 for facilitating the insertion of the free end of the rotating disk 3, and a fixing groove 17 is provided on the center disk 2 to communicate with the slot 9, so when installing the rotating disk 3, the free end of the rotating disk 3 is inserted into the slot 9, at this time, due to the push of the inner wall of the slot 9, the fixed plate 11 rotates around the pin shaft 12, thereby forming abutment with the outer wall of the rotating disk 3, so that the rotating disk 3 can be better inserted into the slot 9 15 , and the fixing plate 11 is rotatable.

[0029] Figure 1-Figure 4 As shown, during disassembly, the fixing plate 11 is pushed into the installation groove 15 so that the fixing plate 11 slides into the installation groove and the fixing plate 11 is separated from the fixing groove 17. At this time, the fixing of the rotating disk 3 is released, and the rotating disk 3 can be moved outward to separate the rotating disk 3 from the center disk 2. This design facilitates disassembly. The above structure can make the operation easier when installing and disassembling the rotating disk 3, and the installation and disassembly are faster.

[0030] Figure 2-Figure 6As shown, a sliding groove 16 is provided on the inner side wall of the mounting groove 15 for facilitating the sliding of the pin shaft 12. When the pin shaft 12 slides in the sliding groove 16, the fixed plate 11 slides into the mounting groove 15. A spring is fixedly connected between the mounting groove 15 and the pin shaft 12 for pushing the pin shaft 12 to slide. When the fixed plate 11 is in the mounting groove 15, the spring is deformed. When the rotating disk 3 is disassembled, the fixed plate 11 is slid into the mounting groove 15. At this time, due to the force, the pin shaft 12 slides in the sliding groove 16 and squeezes the spring 19 during the sliding process, so that the spring 19 is deformed until the fixed plate 11 is completely separated from the fixing groove 17, and the rotating disk 3 is further pulled outward, so that the rotating disk 3 is separated from the center disk 2. At this time, the deformed spring 19 pushes the pin shaft 12 and the fixed plate 11 to reset, thereby facilitating the next use. This design facilitates the sliding of the pin shaft 12 and the fixed plate 11.

[0031] Figure 2-Figure 6 A torsion spring 13 is provided between the pin shaft 12 and the fixed plate 11 to facilitate driving the fixed plate 11 to rotate. When the fixed plate 11 rotates, the torsion spring 13 is deformed, and a embedding groove 14 communicating with the mounting groove 15 is provided on the rotating disk 3. When the torsion spring 13 is deformed, the fixed plate 11 is located in the embedding groove 14 and the fixed plate 11 can only rotate to the side away from the embedding groove 14. Therefore, when the free end of the rotating disk 3 is inserted into the slot 9, due to the extrusion of the inner side wall of the latch, the fixed plate 11 rotates around the pin shaft 12 to the side close to the embedding groove 14, and during the rotation of the fixed plate 11, the torsion spring 13 is deformed. When the free end of the rotating disk 3 completely enters the slot 9 When the rotating plate 11 is inserted into the slot 9, the rotating plate is embedded in the embedding groove 14, which facilitates the insertion of the rotating disk 3 into the slot 9, and when the fixed plate 11 slides to the arc groove, the deformed torsion spring 13 drives the fixed plate 11 to rotate along the arc groove until the fixed plate 11 rotates into the fixed groove 17. At this time, the fixed plate 11 abuts against the inner wall of the fixed groove 17, thereby fixing the rotating disk 3 in the center disk 2. The torsion spring 13 in this design plays a role in driving the fixed plate 11 to reset, and by providing the embedding groove 14, when the rotating disk 3 is inserted into the slot 9, the fixed plate 11 can fit with the rotating disk 3, thereby facilitating the installation of the rotating disk 3 and further improving the convenience of installation.

[0032] Figure 4-Figure 6 A plurality of slots 10 are provided on the inner wall of the slide groove 16, and a block 18 which can engage with the slot 10 is fixedly connected to the pin shaft 12. When the block 18 engages with the slot 10, the fixing plate 11 is located in the fixing groove 17. This design can fix the pin shaft 12 to prevent the pin shaft 12 from sliding as the wheel hub rotates and affecting the fixation of the rotating disk 3. This design plays a role in fixing the pin shaft 12 and the fixing plate 11.

[0033] Figure 2-Figure 8The center disk 2 shown is provided with a plurality of connectors 5 detachably connected thereto, and a push plate 6 is slidably connected thereto. A through hole 7 is provided on the rotating disk 3 for facilitating the insertion of the connector 5, and a plug-in slot 8 communicating with the fixed slot 17 and the through hole 7 is provided on the center disk 2. When the connector 5 is inserted into the plug-in slot 8 and the through hole 7, the push plate 6 pushes the fixed plate 11 to slide into the installation slot 15. A groove is provided on the connector 5, and the push plate 6 slides in the groove. A spring 20 for pushing the push plate 6 to slide is fixedly connected in the groove. Therefore, when the rotating disk 3 needs to be removed, the connector 5 is inserted into the plug-in slot 8 through the through hole 7. At this time, as the connector 5 is inserted, the push plate 6 slides into the groove 21 due to the push of the inner wall of the through hole 7. At this time, due to the extrusion of the push plate 6, the spring 20 is deformed, thereby allowing the connector 5 to be smoothly inserted. In the plug-in slot 8, the push plate 6 is opposite to the fixed slot 17 at this time. Since the force of the through hole 7 on the push plate 6 disappears, the deformed spring 20 pushes the push plate 6 to slide into the fixed slot 17, and at the same time as the push plate 6 slides into the fixed slot 17, the fixed plate 11 is pushed to slide into the installation slot 15, thereby releasing the fixation between the rotating disk 3 and the center disk 2, thereby facilitating the disassembly of the rotating disk 3. This design facilitates the release of the fixation between the rotating disk 3 and the center disk 2, making the disassembly of the rotating disk 3 more convenient and quick, easy to operate, and saving disassembly time. Several connectors 5 are fixedly connected to the same mounting ring 4. Therefore, when disassembling the rotating disk 3, moving the mounting ring 4 can drive several connectors 5 to move together. The mounting ring 4 plays the role of simultaneously moving the used connectors 5, further improving the convenience of disassembly.
