Abstract
The utility model relates to a front floating support chain cover which is suitable for an external speed change bicycle. The front floating support chain cover is mainly provided with a cover body. The front end of the cover body is fixed on a shifting fork of a front speed changer by an open groove and screws, and the rear part of the cover body is fixed on a bicycle frame. The cover body is stamped by an elastic metal thin plate, and thereby, the front floating support chain cover can swing left and right following the shifting fork. The utility model has the advantages of simple structure and convenient installation, and can be used for an external speed change bicycle.
Description
The utility model relates to a kind of bicycle with outer change-speed box and chain guard that can float with Front Derailleur of being applicable to.
Chain guard has been widely used on the non-outer variable speed bicycle, but for outer variable speed bicycle, the vehicle that particularly has Front Derailleur, because the fork of Front Derailleur needs sway, therefore, the chain guard that fixed type supports can't be applied on the outer variable speed bicycle of great majority, though the only a few vehicle has also been used the chain guard of fixed pedestal, but outward appearance is slow-witted, and can not be compatible mutually with the additional block plate of the hinge wheel of existing outer variable speed bicycle.
The purpose of this utility model provides a kind of simple in structure and unsteady support chains cover that can be compatible mutually with the additional block plate of hinge wheel.
The purpose of this utility model can realize in the following manner: a kind of preceding support chains cover that floats of outer variable speed bicycle that is used for, include cover body, the leading section of cover body be useful on the groove that is stuck on the bicycle Front Derailleur fork and with shift fork on the corresponding circular hole of circular hole, the rear end of cover body has and makes it can be placed in circular hole on the cycle frame.
The utility model compared with prior art has following advantage: the front end of chain guard is fixed on the fork of Front Derailleur of outer variable speed bicycle, the rear end is fixed on the vehicle frame, the front end of chain guard can swing with fork, chain guard is easy for installation, simple in structure, just can be made into conventional Sheet Metal Forming Technology.
