The purpose of this utility model is in view of the many disappearances of the generation of above bicycle handle on holding place, but provides a kind of Fast transforms to hold angle, adjusts the auxiliary bicycle handle bar of the easy angular adjustment done.

According to a kind of auxiliary bicycle handle bar of doing adjusting angle of the present utility model; Be to link main body upper end and side by one respectively to be one and to connect but the perforation in different circles footpaths, cooperate be installed in one group in the perforation of upper end in for the semicircular fixture block of concave arc groove, be rotary state to accept auxiliary handle lower end cylinder spheroid, be the location by the upper end lag bolt that wears that periphery is provided with two lugs of boring a hole afterwards; And in the perforation of side, the inclined-plane nut head that must assemble the inclined-plane column jecket of a hollow form and be relative shape combines with an overbolt, to be assemblied in handlebar two ends pipe internal fixation; Change the corrective action of holding angle in order to do thinking, reach quick, the easy effect of regulating conversion with the personal considerations.

On the other hand of the present utility model, provide a kind of auxiliary bicycle handle bar structure of doing adjusting angle; Wherein, this links made two one-body molded lugs on the main body upper end perforation periphery appropriate location, it is that the profile groove gap is arranged one in the centre, and in the middle of two lugs, locate to such an extent that be respectively smoothly and the shape of threads aperture, in order to do being linked to one group of imploded arcs groove semicircular fixture block and arresting to hold down and make any angular adjustment, smoothly reach shape of threads aperture locking positioning by a lag bolt through two lugs again effectively will link auxiliary handle that main body accepted.

One side more of the present utility model is providing a kind of auxiliary bicycle handle bar structure of doing adjusting angle; Wherein, be assemblied in the inclined-plane nut head that the handlebar two ends are managed the inclined-plane column jecket of an interior hollow form and are relative shape, be to utilize an overbolt spiral approaches gradually, so that two inclined-planes are able to slippage and two column jeckets, nut head support are stagnated pastes fixingly with column jecket and nut head, unlikely generation is dropped loosening.

Remainder, now again with regard to the architectural feature of the utility model and operation etc., in the mode that cooperation illustrates, detailed row record and narrate in after.Wherein:

Fig. 1 is the block diagram of known structure and assembling.

Fig. 2 is the three-dimensional icon of the utility model structure.

Fig. 3 is the section-drawing of the utility model combination back.

Fig. 4 is the enforcement illustration of the utility model structure.

Fig. 4 A is the motion diagram of the utility model auxiliary handle spheroid.

At first, see also shown in Fig. 2 explanation: a kind of auxiliary bicycle handle bar structure of doing adjusting angle of the present utility model; Be to be installed on the interior A1 of two ends pipe of Regular Bicycle handle; One binding main body 1 upper end and side respectively are one and connect but the

perforation

11,12 of different-diameter, be the

semicircular fixture block

21,22 of concave arc groove 2A in being installed in one group in the perforation 11 on cooperating, be rotary state (as Fig. 4 A) to accept auxiliary handle 3 lower end cylinder spheroids 31, be provided with two lugs 111,112 that are made into integration by upper end 11 peripheries of boring a hole afterwards, and in the middle of both is that profile groove gap 115 is arranged one, 111,112 center of face places then are respectively smooth holes 113 and tapped bore 114 in its two lug, by a lag bolt 6B two lugs, 111,112 locks are revolved clamping and positioning; And in the larger-diameter perforation 12 of side, must assemble the inclined-plane column jecket 4 of a hollow form and be the inclined-plane nut head 5 of relative shape, it is passed by an overbolt 6A link main body 1, inclined-plane column jecket 4 to 51 combinations of inclined-plane nut head 5 screwed hole of centre.
