Abstract
The utility model discloses a bicycle front fork which comprises a vertical pipe and two branch pipes, wherein one ends of the two branch pipes are connected with the vertical pipe, and the other ends of the two branch pipes are connected with a front wheel horizontal shaft. Connection ends of the branch pipes and the vertical pipe are set to be circular-arc-shaped. By means of the bicycle front fork, the weight of a front fork can be reduced so that the bicycle can be applied to various users and occasions, and the front fork is attractive and elegant.
Description
Technical field
The utility model relates to the bicycle field, particularly relates to a kind of new bicycle front fork.
Background technology
Front fork is the vitals of bicycle, and it comprises the arm of standpipe and two bifurcateds.In the prior art, arm is straight tube, and the junction of arm and standpipe is rectangular-shaped, and the weight of front fork is heavier, causes the weight of car load also heavier, and user's experience sense is relatively poor, and can not be suitable for multiple user.In addition, to requiring the occasion of weight light (for example performance), the front fork of this structure obviously can not meet the demands at some.
The utility model content
Main purpose of the present utility model is to provide a kind of bicycle front fork, is intended to effectively solve the heavier technical matters of the weight of front fork in the prior art.
In order to realize the utility model purpose, the utility model provides a kind of bicycle front fork, comprises standpipe and two arms, and an end of described two arms is connected with standpipe, and the other end is connected with the front-wheel transverse axis, and wherein, the coupling end of described arm and standpipe is set to circular arc.
Preferably, described arm is diminished to an end that is connected with the front-wheel transverse axis gradually by an end that is connected with standpipe.
Preferably, the coupling end of described arm and front-wheel transverse axis is provided with connecting strap, is connected with the front-wheel transverse axis by this connecting strap.
Preferably, be provided with through hole on the described connecting strap.
Preferably, the radius of inner arc is 80 ~ 100mm.
Bicycle front fork in the utility model, the coupling end of its arm and standpipe is set to arc, has therefore alleviated the weight of front fork, so that bicycle can be suitable for multiple user and occasion.In addition, arm is diminished to an end that is connected with the front-wheel transverse axis gradually by an end that is connected with standpipe, has further alleviated weight, and so that front fork is more elegant in appearance.
Description of drawings
Fig. 1 be among the utility model one embodiment bicycle front fork face structural representation;
Fig. 2 is the side-looking structural representation of bicycle front fork among the utility model one embodiment.
The realization of the utility model purpose, functional characteristics and advantage are described further with reference to accompanying drawing in connection with embodiment.
The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
See figures.1.and.2, propose the utility model bicycle front fork one embodiment.Among the utility model embodiment, bicycle front fork comprises standpipe 10 and two arms 20, and an end of described two arms 20 is connected with standpipe 10, and the other end is connected with front-wheel transverse axis (not shown).Described arm 20 is set to circular arc with the coupling end 21 of standpipe 10.
Among the utility model embodiment, arm 20 can be by being welded together with standpipe 10.Its coupling end 21 can pass through the mould bending moulding before welding.Certainly, circular arc described herein might not refer to proper circular arc, and it also can be irregular arc setting, but as long as relative right angle expendable weight.Among the utility model embodiment, coupling end 21 places, the radius of inner arc minimum is 80 ~ 100mm.Inner arc refers to the small arc-shaped relative with front-wheel.
Further, in a preferred embodiment, arm 20 is diminished to an end that is connected with the front-wheel transverse axis gradually by an end that is connected with standpipe 10.That is, the pipe shaft of arm 20 has tapering, and this tapering is descending to the opposite end transition from coupling end 21, relative straight tube, and present embodiment can further alleviate the weight of front fork, and so that front fork is more elegant in appearance.Because coupling end 21 is large ends, do not affect the Joint strenght of arm 20 and standpipe 10, therefore this scheme is feasible.
Shown in seeing figures.1.and.2, among the utility model embodiment, arm 20 is provided with connecting strap 22 with the coupling end of front-wheel transverse axis, is connected with the front-wheel transverse axis by this connecting strap 22.Concrete, being provided with slit port 23 on the connecting strap 22, this slit port 23 is adaptive with the front-wheel transverse axis, can insert for the front-wheel transverse axis.With reference to Fig. 2, in the present embodiment, be provided with through hole 23 on the connecting strap 22.The setting of this through hole 23 can further alleviate the weight of front fork.
Bicycle front fork in the utility model, its arm 20 is set to arc with the coupling end 21 of standpipe 10, has therefore alleviated the weight of front fork, so that bicycle can be suitable for multiple user and occasion.In addition, arm 20 is diminished to an end that is connected with the front-wheel transverse axis gradually by an end that is connected with standpipe 21, has further alleviated weight, and so that front fork is more elegant in appearance.
It below only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification sheets and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
Claims (5)
