AI Technical Summary
Existing luggage universal wheels make a lot of noise and have poor shock absorption when towing, resulting in significant vibration to the hands.
It adopts an inner wheel and outer wheel structure. The inner wheel is made of plastic and the outer wheel is made of rubber. A rubber roller is arranged between the two to form an elastic buffer device. The rubber roller absorbs vibration and reduces noise when rolling.
Effectively reduce noise, reduce vibration transmission, and improve usage comfort.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of luggage accessories, in particular to a shock-absorbing and noise-reducing luggage universal wheel. Background Art
[0002] When existing luggage casters are dragged on the ground, since the wheel body of the luggage caster is generally made of a hard material such as plastic, it will make a loud noise when rolling in contact with the ground. At the same time, the shock absorption ability is poor. When dragging on a bumpy road, the vibration is transmitted to the user's hands, which can easily cause numbness in the hands. Utility Model Content
[0003] The technical problem to be solved by this utility model is to address the deficiencies of the above-mentioned prior art.
[0004] Provided is a shock-absorbing and noise-reducing luggage universal wheel to reduce noise generation and vibration.
[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: A shock-absorbing and noise-reducing universal wheel for luggage, comprising a mounting seat, a wheel seat rotatably connected to the mounting seat, and a wheel rotatably connected to the wheel seat, wherein the wheel comprises an inner wheel and an outer wheel, the inner wheel being rotatably connected to the wheel seat via a rotating shaft, the outer wheel being arranged on the circumferential outer side of the inner wheel, an elastic buffer device being provided between the circumferential inner wall of the outer wheel and the circumferential outer side of the inner wheel, the elastic buffer device comprising a plurality of rubber rollers, a first roller groove being provided along the circumferential outer end face of the inner wheel, a second roller groove being provided along the circumferential inner wall of the outer wheel, the width of the first roller groove and the second roller groove being adapted to the height of the rubber roller, and each of the rubber rollers being rolled between the first roller groove and the second roller groove.
[0006] The utility model has the above characteristics: the rubber roller is elastic, so that the wheel as a whole has shock absorption capability, and at the same time, when rolling in contact with the ground, the rubber roller deforms to absorb vibration and reduce noise generation.
[0007] A further configuration of the present invention is that adjacent rubber rollers abut against each other.
[0008] The utility model with the above features can make the rubber rollers fill the first roller groove and the second roller groove, increase the fullness between the outer wheel and the inner wheel, and ensure the supporting force of the wheel.
[0009] A further configuration of the present invention is that the inner wheel is made of plastic.
[0010] The utility model with the above characteristics ensures the hardness of the inner wheel.
[0011] A further configuration of the present invention is that the outer wheel is made of rubber.
[0012] The utility model with the above characteristics reduces the hardness of the outer wheel, thereby reducing the noise generated when the outer wheel contacts the ground and avoiding the noise emitted by rigid contact.
[0013] A further configuration of the present invention is that the outer wheel and the inner wheel have the same axial thickness.
[0014] The utility model with the above features ensures that the width of the outer wheel is consistent with that of the inner wheel, thereby preventing the outer wheel from being too wide and interfering with the wheel seat.
[0015] The beneficial effects of the utility model are: reducing noise and reducing vibration.
[0016] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
[0017] Figure 1 It is a three-dimensional schematic diagram of an embodiment of the present utility model.
[0018] Figure 2 This is a cross-sectional schematic diagram of a wheel according to an embodiment of the present utility model. DETAILED DESCRIPTION
[0019] like Figure 1 、 Figure 2 The shown type of shock-absorbing and noise-reducing luggage universal wheel includes a mounting base 1, a wheel seat 2 rotatably connected to the mounting base 1, and a wheel 3 rotatably connected to the wheel seat 2, the wheel 3 includes an inner wheel 301 and an outer wheel 302, the inner wheel 301 is rotatably connected to the wheel seat 2 via a rotating shaft 4, the outer wheel 302 is arranged on the circumferential outer side of the inner wheel 301, and an elastic buffer device is provided between the circumferential inner wall of the outer wheel 302 and the circumferential outer side of the inner wheel 301, the elastic buffer device includes a plurality of rubber rollers 5, the inner wheel 301 is provided with a first roller groove 6 along the circumferential outer end face, the outer wheel 302 is provided with a second roller groove 7 along the circumferential inner wall, the width of the first roller groove 6 and the second roller groove 7 are adapted to the height of the rubber roller 5, each rubber roller 5 is rolled between the first roller groove 6 and the second roller groove 7, and adjacent rubber rollers 5 abut against each other, the inner wheel 301 is made of plastic, the outer wheel 302 is made of rubber, and the outer wheel 302 and the inner wheel 301 have the same axial thickness.
[0020] The rubber roller 5 is elastic, so that the wheel 3 as a whole has shock absorption ability. At the same time, when rolling in contact with the ground, the rubber roller 5 deforms to absorb vibration and reduce noise. The rubber roller 5 fills the first roller groove 6 and the second roller groove 7, increasing the fullness between the outer wheel 302 and the inner wheel 301, ensuring the supporting force of the wheel 3. The inner wheel 301 is made of plastic to ensure the hardness of the inner wheel 301. The outer wheel 302 is made of rubber to reduce the hardness of the outer wheel 302, so that when it contacts the ground, the noise generated is reduced and the noise emitted by rigid contact is avoided. The outer wheel 302 and the inner wheel 301 have the same axial thickness to ensure that the width of the outer wheel 302 and the inner wheel 301 are consistent, avoiding the outer wheel 302 being too wide and interfering with the wheel seat 2.
