Below in conjunction with drawings and Examples bicycle adjustable bicycle handlebar of the present utility model is explained in detail:

Fig. 1 is the cutaway drawing of the side-looking of the utility model bicycle adjustable bicycle handlebar;

Fig. 2 is the cutaway drawing of adjustable bicycle handlebar along A-A face among Fig. 1.

As Fig. 1 and Fig. 2, the column 2 of handlebar is housed in the preceding wooden fork pipe 1 of cycle frame, preceding wooden fork pipe is stretched out on the top of column 2, its top cross with short tube 3 fixing (as with welding) sleeve 4 is arranged, sleeve 4 has certain thickness, (decide on the size that handlebar need be regulated in certain angle on the same circumference in middle part its outside, as Fig. 1), promptly in one section circumferential segment (as 90 °-120 °) equidistant be fixed with several screws 6, (also depend on the needs, be generally 5-6, present embodiment is 5), locating rack 7 is made up of a cylinder 12 and two legs 13, the two ends of cylinder 12 are porose, the pipe of handlebar grip 11 is fixed therein, leg 13 is porose, have with little axle 5 in the hole that penetrates this hole and sleeve 4 of cooperation and make locating rack 7 and 4 rotating connections of sleeve, the end of little axle has nut 10 that little axle can not deviate from, there is a transverse holes at the middle part of cylinder 12, radius stay 8 is with this hole of passing of suitable cooperation (removable but do not have excessive gap), one end of radius stay 8 have the screw that cooperates with screw 6 and with screw 6 in one combine, the other end of radius stay 8 has a step and a knurling handle, knurling handle can be held with staff and radius stay and screw 6 are tightened or be unclamped, then in order to radius stay is located on locating rack, 9 is a pad to step.

When radius stay 8 being unclamped on screw 6 and breaking away from, locating rack is changeed an angle around little axle 5, radius stay is combined with another screw 6, then the position of handlebar grip 11 changes to some extent, (shown in the imaginary line of Fig. 1), can change the position of handlebar to vehicle seat, when radius stay and screw are screwed to certain position, the step and the locating rack of radius stay are close to, after tightening, the engagement limits of radius stay and positioning frame hole the rotation of locating rack, simultaneously the thrust of step also makes locating rack not rotate, and therefore locating rack is fixed on certain position.

If do not need to regulate, can all twist tightlyer radius stay 8 and nut 10, it is motionless that locating rack can be fixed on certain position.

Should be noted that this adjustment can only carry out under the situation of stopping, can not under the situation of riding, unclamp radius stay, otherwise be movable between handlebar grip and the sleeve, can cause danger.
