Description
Technical field
It the utility model is related to a kind of bicycle front derailleur, more particularly to dialled before a kind of controllable bicycle of setting angle
Chain device.
Background technology
A kind of existing bicycle front derailleur includes pedestal and is rotatably connected on by inboard Sinks and outer link
The chain guide of swing rod is formed on pedestal, the stretching end for line of shifting gears is fixed on inside connecting rod, outer link or chain and is oriented to
On part, when gearshift line length change, gearshift line then to inside connecting rod, outer link or chain guide produce influence or
Motive force, make chain guide that directional swing occur, the chain through chain guide is directed into another horizontal level, with original
Coordinate sprocket wheel to release and coordinate with another sprocket wheel, realize gearshift.
Wherein, clamp assemblies are provided with pedestal, clamp assemblies include fixed part relatively-stationary with pedestal and movable part,
The first end of fixed part and the first end of movable part are rotatablely connected, and the second end of fixed part and the second end of movable part pass through bolt
Realization is detachably connected, between fixed part and movable part formed clamping road, bicycle front derailleur by clamp assemblies clamping with
On the vehicle frame of bicycle.
The problem of existing this kind of bicycle front derailleur is present be, because clamp assemblies are fixed relative to pedestal, when from
After front chain mover of driving a vehicle is arranged on vehicle frame by clamp assemblies, bicycle front derailleur is then maintained with vehicle frame and is relatively fixed.
But there is different models because the processing of vehicle frame has error or vehicle frame, the standpipe of vehicle frame can have angle difference, front derailleur
Device is installed to after standpipe then there may be angular deviation, then can bring the functional impact of front chain mover.
The content of the invention
The purpose of this utility model is to provide a kind of setting angle controllable bicycle front derailleur.
Bicycle front derailleur provided by the utility model includes pedestal, inboard Sinks, outer link and chain guide,
Inboard Sinks are be hinged with pedestal and inboard Sinks are hinged with chain guide, and outer link is hinged with pedestal and outer link and chain
Bar guide is hinged；Clamp assemblies are provided with pedestal, clamp assemblies include fixed part and movable part, the first end hinge of movable part
The first end of fixed part is connected to, the second end of movable part and the second end of fixed part are locked by bolt, movable part and fixed part
Between formed clamping road；Clamp assemblies also include the first inner piece and the second inner piece, and the first sphere of the first inner piece is with consolidating
The second spherical surface for determining portion is engaged, and the 3rd sphere of the second inner piece and the 4th spherical surface of movable part are engaged；The
First inner surface of one inner piece is set relatively with the second inner surface of the second inner piece in road is clamped.
From such scheme, after clamp assemblies clamp to the standpipe of vehicle frame, the first inner piece and the second inner piece
Be connected on standpipe, due to the first inner piece and the second inner piece respectively with fixed part and movable part sphere-contact, the first liner
Part and the second inner piece have the free degree of rotation relative to fixed part and movable part ball, first adjust pedestal angle, after to folder
Hold component to be locked, to control the setting angle of front chain mover, ensure that the function of front chain mover is unaffected.
Further scheme is that the first sphere and the 3rd sphere are outer convex spherical, and the second sphere and the 4th sphere are indent
Sphere.
Further scheme is that the end face of the first inner piece can be connected to fixed part, and the end face of the second inner piece can abut
In movable part.
