The invention relates to the technical field of luggage casters, in particular to a luggage shock-proof universal wheel which comprises a mounting seat and two connecting shafts, bearings are mounted on the surfaces of the connecting shafts, and casters are mounted on the outer edges of the bearings; the damping mechanism is used for damping the caster, and the damping mechanism is arranged between the two connecting shafts; when the luggage drives the trundles to run on a bumpy road surface through the pressure bearing mechanism, the trundles can vibrate under the action of the gravity of the luggage, at the moment, the trundles can drive the bearings and the connecting shafts to swing upwards in the movable grooves through the hinge bases and the hinge heads, and the connecting shafts can drive the movable cylinders to slide in the sleeves through the second universal joints when swinging up and down; at the moment, the movable cylinder extrudes the first spring, so that the vertical reciprocating swing absorbs and slows down the vibration force borne by the caster, and the probability that the connecting part of the caster is damaged is reduced.
本发明涉及箱包脚轮技术领域,具体的说是一种箱包避震万向轮,包括:安装座和连接轴,所述连接轴的数量为两个,所述连接轴的表面安装有轴承,所述轴承的外缘安装有脚轮;减震机构,用于对所述脚轮进行减震的所述减震机构设置于两个所述连接轴之间;当箱包通过承压机构带动脚轮行驶在颠簸路面时,脚轮在箱包重力的作用下会出现振动现象,此时脚轮会带动轴承和连接轴通过铰接座和铰接头在活动槽向上摆动,连接轴在上下摆动时会通过第二万向节带动活动筒在套筒内滑移,此时活动筒会对第一弹簧进行挤压,如此上下往复摆动将脚轮受到的振动力给吸收和减缓,降低脚轮的连接部位出现损坏的概率。
