Abstract

The invention relates to the field of trundles, and provides a universal wheel. The universal wheel comprises a bearing, a bearing pedestal, a dust cover, a mounting plate, a lower steel bowl, a fixing rivet, a fork foot and a rolling wheel. The bearing pedestal coats the outer side wall of the bearing and supports the lower end of an outer ring of the bearing. The dust cover presses the upper end of an inner ring of the bearing and is provided with a side ring which is placed on the outer side of the bearing pedestal. The mounting plate presses the dust cover and is provided with a plurality of mounting holes. The lower steel bowl presses the lower end of the inner ring of the bearing. The fixing rivet penetrates through the mounting plate, the dust cover, a bearing inner hole and the lower steel bowl. The fork foot is provided with two side plates and a top plate which is arranged outside the bearing pedestal in a sleeved mode and is connected with the bearing pedestal. The rolling wheel is connected with the two side plates in a pivoted mode. The bearing of the universal wheel is placed among the bearing pedestal, the lower steel bowl and the dust cover and can be protected by the side ring of the dust cover, the bearing capacity of the universal wheel is good, bearing protection is good, and the universal wheel cannot be stained and damaged easily.

Description

technical field [0001] The invention relates to the field of casters, in particular to a universal wheel. Background technique [0002] The utility model of Chinese patent application number: CN200920220173.9 discloses a universal wheel, which includes a wheel seat and a caster. The lower shaft of the caster is provided with a wheel. There is not less than one fixing hole on the back for fixing the wheel base on the luggage; a rivet is fixed at the center of the upper end of the wheel caster, and the rivet is inserted into the bearing to fix the wheel base and the caster together. The universal wheel has the disadvantages of poor load-carrying capacity and poor bearing protection, which is easy to be damaged by pollution; therefore, it is an urgent problem to design a universal wheel with better load-carrying capacity and better bearing protection, which is not easy to be damaged by pollution. Contents of the invention [0003] The purpose of the present invention is to o...
