[0003] The utility model patent CN220494448U discloses a noise-dampening and vibration-reducing luggage wheel, including a luggage body. A luggage wheel mechanism is located at the bottom of the luggage body. A pull rod mechanism is fixedly connected to one outer surface of the luggage body. The luggage wheel mechanism includes a wheel body. A noise-dampening hole is formed on one outer surface of the wheel body. The wheel body is rotatably connected to the outer wall of a silent shaft. A U-shaped plate is fixedly connected to the outer wall of the silent shaft. The inner walls of opposite sides of the U-shaped plate are fitted with the outer walls of opposite sides of the wheel body. A telescopic rod is fixedly connected to the top of the U-shaped plate. A first spring is sleeved on the outer wall of the telescopic rod. A connecting block is fixedly connected to the top of the telescopic rod. This utility model allows for the installation and disassembly of the luggage wheel mechanism and the luggage body by pulling a ring, providing convenient installation and disassembly. The noise-dampening hole and silent shaft reduce noise caused by wheel rotation, and the first spring reduces vibration generated by the luggage body during pulling.

[0004] In the above-disclosed structure, a shock-absorbing structure is formed by inserting and installing rollers at the bottom of the housing. However, the structure lacks a shock-absorbing ring structure with a combined ring connection, so it cannot be assembled separately to form rollers, making it impossible to replace parts locally. Furthermore, it cannot be assembled with positioning bearings, which easily creates gaps and causes shaking, resulting in significant vibration and noise. The performance is poor and needs improvement. Utility Model Content
