Description

The compound type rim

The utility model relate to a kind of from the wheel the structure of the airtyred rim of dismounting, its compound type structure can make air tyre not need special tool to make things convenient for, dismounting from the rim quickly.

At present, well-known air-inflation tyre is to be contained on the rim of wheel, in order to prevent skidding off of tire, two peripheries of rim are done be higher than the middle part and with whole rim be one, inseparable, we are referred to as fixed edge.The rim of this structure has caused tire to change the difficulty of tearing open, not that is to say and be difficult to tire is pulled down from rim by means of special instrument, and integral body is changed the method for wheel for bicycle, dillies such as motor bike are owing to the reason of the assembled configuration of wheel, make operation very complicated, make from the side and cost considers it is unpractical, for Oversize vehicles such as automobiles, changing wheel also is a very thing of headache to women and weakling, and the thing of often blowing out occurs on field or the road, because the restriction of condition has more increased difficulty for maintenance.

The purpose of this utility model just provides a kind of later-model wheel rim, and it can make the air tyre just dismounting easily under the situation of not using special tool on the rim.

The purpose of this utility model is achieved in that making up rim is made up of connecting element and rim main body, connecting element is a fixed edge of former rim, promptly can be all also can be a part of, can cut apart by former rim and make, can independently make again, the rim main body is made into to have only the member of a fixed edge during independent the manufacturing.Connecting element and rim main body are connected by attaching parts.When the need dismounting air tyre, attaching parts is taken apart, take down connecting element, i.e. dismantled and assembled air tyre.

Owing to adopt such scheme, when making from rim the dismounting air tyre, do not need special tool just conveniently to carry out quickly.
