Abstract

A foam wheel assembling and positioning structure includes a wheel frame having a plurality of ribbed plates thereon and a wheel body covering the ribbed plates. The wheel body has a penetration hole. A first fixing part is formed on a peripheral edge of the penetration hole and provided with a plurality of first fixing holes thereon. Two wheel covers are fixed oppositely on the wheel frame. Each wheel cover has a positioning hole thereon, and a positioning screw penetrates into the positioning hole and is screw-locked with a positioning nut. Furthermore, a peripheral edge of each wheel cover has a second fixing part which has second fixing holes thereon. A fixing element is fixed in the first and second fixing hole, so as to fix the wheel body onto the wheel frame and the wheel covers, thereby avoiding detachment caused by relative sliding during traveling.

Claims

1. A foam wheel assembling and positioning structure, comprising:

a wheel frame provided with a plurality of ribbed plates, wherein through holes are formed between the ribbed plates;

a wheel body covering the ribbed plates of the wheel frame, wherein the wheel body is provided with a penetration hole, a first fixing part of the wheel body is formed correspondingly on a peripheral edge of the penetration hole, and the first fixing part is provided with a plurality of first fixing holes thereon;

two wheel covers fixed oppositely on the wheel frame, wherein each wheel cover is provided with a positioning hole, a positioning screw penetrates into the positioning hole, and the positioning screw is screw-locked with a positioning nut, and a peripheral edge of each wheel cover is provided with a second fixing part which is provided with a plurality of second fixing holes thereon corresponding to the first fixing holes; and

at least one fixing element fixed in the corresponding first and second fixing holes.

2. The foam wheel assembling and positioning structure of claim 1, wherein the fixing element is a bolt and is used for screwing with a fixing nut.
