Detailed Description
The damping mechanism of the luggage of the present invention will be further described with reference to fig. 1.
The utility model provides a damper of suitcase, includes fixing base subassembly 1, wheelset subassembly 4 and damper, characterized by: the shock absorbing assembly includes a rotating shaft 3 and a conical spring 2.
The fixing seat assembly 1 comprises a fixing seat 12 and a rotary gasket 11, the fixing seat 12 is provided with a central assembly hole 121, the assembly hole is provided with an upper guide section and a lower installation section, the diameter of the upper guide section is smaller than that of the lower installation section, an inner step is formed between the upper guide section and the lower installation section, and the gasket is located on the inner step.
The upper end of the rotating shaft 3 penetrates through the rotating gasket to be matched with the upper guide section and can be axially movably arranged, and the lower end is axially limited and connected to the wheel set assembly 4.
The conical spring 2 is sleeved on the rotating shaft 3, the upper end of the conical spring 2 abuts against the rotating gasket 11, and the lower end of the conical spring 2 abuts against the flange 33 of the rotating shaft 3.
In the damping process, the conical spring 2 can be compressed into a surface, and compared with a spring in the prior art, the axial distance occupied after the conical spring is compressed is obviously reduced, so that the reservation of the space between the wheel set assembly and the fixed seat 12 is saved, the distance between the fixed seat 12 and the wheel set assembly is reduced, and the stability between the fixed seat 12 and the wheel set assembly is improved; on the other hand, the stress of each section of the conical spring 2 is different, namely the stress is gradually increased, so that the conical spring is more stable in deformation and shock absorption; the rotary gasket 11 is arranged to facilitate the rotation of the wheel set assembly 4 relative to the fixed seat assembly 1; in this embodiment, the upper end of pivot 3 can move about for fixing base subassembly 1, the lower extreme is fixed for wheelset subassembly 4, owing to set up conical spring 2 has saved the reservation of space between wheelset subassembly 4 and the fixing base subassembly 1, has reduced the distance between the two promptly, consequently even the upper end of pivot 3 moves for fixing base subassembly 1, it is little to the installation of box and whole shock attenuation effect influence, it is opposite movable for the 3 lower extremes of pivot, the problem that the lower extreme of pivot 3 still can avoid touching to the ground.
