Little, when rear tooth disk is the biggest, more feel relief during pedal.According to the ability of different drivers, can be by adjusting forward and backward fluted disc
Size adjust the speed of bicycle, or tackle different section, road conditions.
Current bicycle speed-varying unit generally comprises multistage flying wheel, and controls chain gearshift of switching between different flywheels
Device and derailleur.Wherein connect between selector and derailleur and have steel wire, for transmission motion between the two.And steel wire
Line outlet is typically provided with outlet cap, is used for protecting steel wire to be difficult to impaired, and makes motion transmission more steady.And existing product
In product, part outlet cap is adopted made of plastic, and owing to contacting with steel wire always, easily friction is impaired after long-term use, loses
Remove its Protection significance；Also part outlet cap is had to use metal to make, although this outlet is longer for service life, but also president
Phase and steel wire friction, it is possible to cause the abrasion of steel wire, affect the service life of whole variator.
Therefore, how the outlet cap of bicycle speed-varying unit is improved so that it is overcome disadvantages mentioned above, be this area skill
Art personnel's problem demanding prompt solution.
Utility model content
Main purpose of the present utility model is the bicycle speed-varying unit providing a kind of life-span long, effective to steel wire protection
Outlet cap.
For reaching object above, the technical solution adopted in the utility model is: the outlet cap of a kind of bicycle speed-varying unit,
Including the cap body being provided with wire cavity, it is characterised in that: also include that spheroid and ring body, described spherical ball are articulated with described cap body
Inner side, described ring body is rotationally connected with inside described spheroid, described spheroid is provided with out drawing lines, described ring body is provided with
Wire hole, described wire cavity, goes out drawing lines and wire hole is mutually communicated, to allow steel wire to pass through.By said structure, steel wire
Move between selector and derailleur, can freely carry out angular transformation, without contacting the cap mouth of Long Term Contact outlet cap
Wear and tear.
As preferably, described wire cavity upper end is communicated with ball pivot chamber, and described spheroid is arranged on described ball pivot intracavity.Ball pivot
Chamber and spheroid constitute typed ball bearing pair, can carry out the freely rotatable of multiple angle.
Further, described in go out drawing lines week side be provided with rotation chamber, described ring body is arranged on described rotation intracavity.Rotate chamber
Constitute revolute pair with ring body, the rotation along outlet cap circumference can be carried out.
As preferably, described ring body section is circular, and corresponding described rotation chamber sidewall is circular arc.By above-mentioned knot
Structure, wire hole can be formed the most tubaeform, thinks the line outlet at uncommon right angle, can reduce the friction to steel wire, improve
Its service life.
As preferably, described cap body and described spheroid use metal to make, and described ring body uses elastomeric material to make.Gold
The selection belonging to material can improve the service life of outlet cap, and the selection of elastomeric material can reduce the mill to steel wire further
Damage.
Further, described cap body and described spheroid use rustless steel to be fabricated by, and described ring body uses smooth surface
The rubber processed is fabricated by.Rustless steel intensity and coefficient of friction all meet the requirements, and rubber is a kind of conventional elastomeric material,
Can ensure that steel wire freely slides in wire hole through smooth treatment.
As improvement, described cap body outer surface is provided with anti-slip tank.Facilitate outlet cap to install and change.
Further, described cap body lower end is provided with connection post.Connect post can be connected on selector, it is also possible to connect
In derailleur, outlet cap is a kind of general purpose accessory.
Compared with prior art, the utility model has the advantage of: being articulated with inside cap body by spherical ball, ring body turns
Be dynamically connected the structure inside cap body, and steel wire moves between selector and derailleur, can freely carry out angular transformation, and
The cap mouth that will not contact Long Term Contact outlet cap weares and teares.Reach service life long, the purpose effective to steel wire protection.
