Abstract

The invention relates to a pluggable universal caster wheel belonging to the technical field of common caster wheels and comprising a main shaft, a steel ball, a support, a bolt, a nut, a wheel, a beam barrel and a shaft housing, wherein the beam barrel comprises a bottom housing, a beam barrel body and an upper cover comprising a top insert buckle and a lower end slotted hole, and the shaft housing is fixedly connected with a case; the upper end of the top insert buckle is of a clamping structure, and the top insert buckle and the shaft housing are in buckling connection; the clamping structure is a left elastic structure and a right elastic structure symmetrically arranged mutually; the lower end slotted hole of the upper cover of the beam barrel is an inward bulge slotted hole; the upper end of the main shaft is buckled in the inward bulge slotted hole of the upper cover; the number of the steel ball is only one; the steel ball is arranged between the lower end inward bulge slot of the upper cover and the upper end of the main shaft and is in rolling connection. The invention has the advantages of simple structure, convenient manufacture and easy installation and disassembly; when the wheel is damaged, only the clamping structure needs to be pulled to change the caster wheel, and therefore, the case can continuously work. The invention can be widely applied to objects of cases, carts, baby carriers, seats, medical carriages and the like.

Description

technical field [0001] The invention relates to a universal caster, in particular to a pluggable spindle universal caster, which belongs to the technical field of general casters. Background technique [0002] The universal caster device is a component installed on the bottom of the object to make it easy to move. It is widely used in products such as carts, boxes, and seats, and is indispensable for people in the fields of home, travel, and medical treatment. The universal rotation of the universal caster produced in the prior art all is made by the principle of plane bearing or ball bearing. This kind of universal rotating device has a large number of rollers, various ball positions, complex structure and high production cost. The existing castors are fixed on the bottom of the box and cannot be disassembled from the box. The box body is generally not easy to be damaged during use, but the casters are easily damaged during use, so once the casters are damaged, the entire...
