[0002] At present, when the general bicycle rotator device is braked tightly, the brake line will pull up the rotating collar, positioning seat and brake line together to move upwards. After the brake is released, the rotating collar and positioning seat will move along the front fork pivot axis. Sliding down to return to the original position, because the stunt bicycle has strict requirements on the brake return positioning mechanism, the brake line needs to be quickly returned to the position, and generally the existing stunt bicycle spinners are not designed to rotate the collar and position after braking. Seat and brake cable quick return positioning mechanism, there are still room for improvement

The invention discloses a rotator device of a bicycle. The rotator device includes a frame front pipe, an upper bead bowl group, a brake mechanism, upper brake lines, and springs; the springs are arranged on the top end of the frame front pipe in a recessed manner; the upper bead bowl group is fixed on the top end of the frame front pipe; the brake mechanism is arranged in an accommodation hole and includes a sliding seat and an upper rotation seat; the upper rotation seat rotatably sleeves the sliding seat; the brake lines are clamped on the upper rotation seat; and the springs correspondingly sleeve the brake lines, and are pressed against the upper bead bowl group and the upper rotation seat. The bicycle is braked, and the compressed springs generate restoring expansion force to allow the upper rotation seat, the sliding seat and the lower rotation seat to move downward, drive the upper brake line and the lower brake line to rapidly recover and be positioned. The practicability of the rotator device is very excellent; the brake lines can rapidly recover to the original positions; and the rotator device is easy to maintain.
Description
technical field [0001] The invention relates to the field of bicycle parts, in particular to a bicycle rotator device. Background technique [0002] At present, when the general bicycle rotator device is braked tightly, the brake line will pull up the rotating collar, positioning seat and brake line together to move upwards. After the brake is released, the rotating collar and positioning seat will move along the front fork pivot axis. Slide down to return to the original position. Since the stunt bicycle has strict requirements on the brake return positioning mechanism, the brake line needs to be quickly returned to the position. However, the existing stunt bicycle spinners are not designed to rotate the collar and position after braking. Seat and brake line quick recovery positioning mechanism, there are still room for strengthening and improvement. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects ...
