Abstract
The utility model relates to a fixing device for a bicycle handlebar stem with electric aiding drive, which belongs to the bicycle parts and is composed of a vertical pipe and a joint which are connected together into an integral structure. The utility model has the advantages that the problem of an upper and a lower parts getting loosened easily is radically solved for the vertical pipe and the joint are connected together in an integral structure, and the strength of the handlebar is improved.
Description
The utility model belongs to a kind of attachments of a bicycle, particularly a kind of anchor fitting of assisted electric bicycle handlebar.
The anchor fitting of the handlebar that producer adopted of domestic production Electrical Bicycle is the handle riser of bicycle use at present.Some handlebar anchor fittings that Electrical Bicycle adopted than higher gears are aluminum alloy manufacturing basically, are force fits between joint and the standpipe.Sometimes also add metal adhesive, purpose be for upper and lower cooperation firm, with anti-loosening.However, still there is following shortcoming in the anchor fitting of this kind handlebar: 1, aluminum alloy joint intensity is low, and fragility is big, fracture easily, and the rider was once repeatedly taken place by the example of tumble injury.2, be that depended on pressure and metal adhesive combine owing to aluminum alloy joint cooperates with standpipe, therefore loosening phenomenon easily takes place between the two, in case this kind phenomenon occurs, when the cyclist need turn round, handlebar and joint rotated, and standpipe is loosening, the bottom is malfunctioning, wheel continues to overtake, and the cyclist is tumble injury very easily, even cause major traffic accidents.
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and provides a kind of joint and standpipe to link the anchor fitting of firm assisted electric bicycle handlebar.
As above design, the technical solution of the utility model is:
A kind of anchor fitting of assisted electric bicycle handlebar is made up of standpipe and joint, it is characterized in that, standpipe and joint are structure as a whole.
The utility model has the advantages that: because standpipe and joint are structure as a whole, fundamentally eliminate upper and lower loosening problem, the intensity of handlebar is improved.
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is a section-drawing of the present utility model.
Fig. 2 is a birds-eye view of the present utility model.
As shown in the figure, a kind of anchor fitting of assisted electric bicycle handlebar is by the joint 2 integrally welded structures of the standpipe 1 and the steel of steel.
