Abstract

An auxiliary handlebar device of a bicycle comprises a binding base, a rotary clipping base, an auxiliary handle bar and an elbow backup plate. The binding base comprises a first clipping base and a second clipping base, with the two involutorily wrapping the bicycle handlebar. A secondary punch axially parallel with the handlebar is positioned on the first clipping base for the rotary clipping base to be reversibly arranged on the secondary punch. A socket axially crossed with the handlebar is positioned on the rotary clipping base for the auxiliary handlebar to pass through and bind with the socket and then extend forward. The elbow backup plate is arranged on one side of the second clipping base. As the auxiliary handlebar of the utility model is arranged on the binding base via the rotary clipping base, the plunge and elevation angle of the auxiliary handlebar can be adjusted to meet the optimal holding angle of riders and to reduce muscle tiredness.

Description

The auxiliary handlebar device of bicycle

Technical field

The utility model system belongs to the technical field of bicycle, refers to a kind of bicycle auxiliary handlebar especially.

Background technology

Ride and compete for speed when using bicycle, need bend to reduce windage, so two ends of its handlebar system is made as curved downwards, to reduce the health height, again in order to be altered one's posture for the rider, so there is the dealer to design a kind of auxiliary handlebar device that is installed on handlebar again, see also Fig. 5, shown in 6, described handlebar auxiliary device 60 is to be installed on handlebar 50 stage casings, it comprises a connecting support 61, one is installed on the connecting support 61 and the auxiliary handlebar 62 that extends towards bicycle the place ahead, and one be installed on the armrest plate 63 of connecting support 61 corresponding to the bicycle outside, wherein, described connecting support 61 is to be installed on the handlebar 50 with removable shape, its top is integrally formed with two intermediate plates 610, contiguous free end is provided with a clip slot 611 between two intermediate plates 610, and contiguous handlebar 50 these ends are provided with a perforation 612 that communicates with clip slot 611, be inserted in perforation 612 for described auxiliary handlebar 62, and place spiral shell by two bolts 615 and be located at two side perisporiums of clip slot 611 and fix, this two auxiliary handlebar 62 is this section and be made as the grip part 620 that bends an angle up forward.

Be correspondingly positioned on the intermediate plate 610 of bicycle lateral direction in conjunction with a fixed block 613 in two connecting supports 61 again, in the fixing described armrest plate 63 of fixed block 613 end faces, for user's elbow against, and hold the grip part 620 of auxiliary handlebar 62.
