Description
Technical field
This utility model relates to bicycle accessories field, is specifically related to bicycle speed-varying unit, particularly relates to a kind of sideslip certainly
Driving front derailleur.
Background technology
The most a lot of bicycles are equipped with speed change system.The effect of bicycle shift system is through changing chain
Cooperation with the toothed disc of different forward and backward sizes changes speed speed.The size of front fluted disc and the size of rear tooth disk determine
Dynamics during bicycle turn pedal.Front fluted disc is the biggest, and rear tooth disk more hour, is more felt laborious during pedal.Front fluted disc is more
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.Selector is also
It is referred to as front derailleur, mainly includes the parts such as housing, handle, serving part, pipe axle and steel cable.Current front derailleur is general
Grabbed carrying out speed change by rotation.It addition, during general high speed is ridden, the both arms of bicyclist can be toward contract, and palm is past simultaneously
Lean in the middle of handlebar, to reduce air drag.
Therefore, it is necessary to arrange a kind of new variator, to meet the requirement of riding of people.
Utility model content
Main purpose of the present utility model is that providing a kind of can carry out the sideslip of speed change voluntarily by sliding laterally variator
Herba Plantaginis variator.
For arriving object above, the technical solution adopted in the utility model is: a kind of sideslip Bicycle front derailleur, bag
Include housing, grab handle, steel cable, rotating shaft and serving part, and through the vertical handgrip of described variator, described in grab being fixed in institute
State on housing, described serving part be arranged on described housing and described grab between, described steel cable is connected on described serving part,
It is characterized in that: described axis of rotation is connected in described housing, and described rotating shaft drives described serving part to rotate, described turn
It is provided with feed screw nut in axle, described vertical handgrip is provided with screw mandrel section, axial along described vertical handgrip to realize described variator
While movement, described rotating shaft rotates, and then drives described serving part to rotate.By said structure, only need to hold and grab
, promotion is grabbed handle and housing and is slided on vertical handgrip, can be achieved with serving part and rotates, and then carries out speed change.By screw thread
Turn-around design can realize further, and variator is accelerated to inner slide when, make palm and arm to contract,
Meet custom when common people ride at a high speed.
As improvement, described vertical handgrip is additionally provided with line slideway, described housing coordinates with described line slideway
Rectilinear projection, can only be carried out along the axial straight-line displacement of described vertical handgrip realizing described housing.Ensure only rotating shaft and serving
Part rotates, housing and grab can only straight-line displacement, conveniently realize speed change.
Further, described vertical handgrip end is provided with straight line tread plate vertically, described in grab outside be provided with along week
To circular tread plate.Improve the non-skid property of variator, make speed change relatively reliable.
Compared with prior art, the utility model has the advantage of: by feed screw nut and the cooperation of screw mandrel section, only need
Holding and grab handle, promotion is grabbed handle and housing and is slided on vertical handgrip, can be achieved with serving part and rotates, and then carries out speed change.Pass through
The turn-around design of screw thread can realize further, and variator is accelerated to inner slide when, makes palm and arm inside
Shrink, meet custom when common people ride at a high speed.

Detailed description of the invention
Hereinafter describe and be used for disclosing this utility model so that those skilled in the art are capable of this utility model.Hereinafter retouch
Preferred embodiment in stating is only used as citing, it may occur to persons skilled in the art that other obvious modification.
As shown in Fig. 1～7, an embodiment of the present utility model include housing 1, grab 2, steel cable 3, rotating shaft 4 and
Serving part 5, and the vertical handgrip 6 through variator, grab and be fixed on housing 12, and serving part 5 is arranged on housing 1
And grab between 2, steel cable 3 is connected on serving part 5.It is critical that rotating shaft 4 is rotationally connected with in housing 1, and turn
Axle 4 drives serving part 5 to rotate, and is provided with feed screw nut 41, vertical handgrip 6 is provided with screw mandrel section 61 in rotating shaft 4, with
Realizing while variator moves axially along vertical handgrip 6, rotating shaft 4 rotates, and then drives serving part 5 to rotate.Handlebar
Being additionally provided with line slideway 62 on bar 6, the rectilinear projection 11 that housing 1 coordinates with line slideway 62, to realize housing 1
Can only carry out along the axial straight-line displacement of vertical handgrip 6.
In order to increase non-skid property, vertical handgrip 6 end is provided with straight line tread plate 63 vertically, grabs and sets outside 2
It is equipped with circular tread plate 21 circumferentially.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.One's own profession
