Abstract

The invention provides a bicycle rotating folder, which comprises a lower rotating base, a tooth disk, an upper rotating base, a rotating pin and an eccentric spanner; the tooth disk is fixed in the lower rotating base, and the tooth disk is evenly provided with a mesh tooth part on a peripheral direction; the upper rotating base is provided with a matching tooth part meshed with the mesh tooth part; one end of the rotating pin is fixed on the lower rotating base, and the lower end is hinged with the eccentric spanner by crossing through the upper rotating base; a spring is mounted between the lower rotating base and the upper rotating base; the eccentric spanner is rotated so that the matching tooth part of the upper rotating base is isolated from the tooth disk; the upper rotating base is rotated to rotate and fold; the eccentric spanner is locked, thus the matching tooth part is meshed with the corresponding mesh tooth part. The upper rotating base of the bicycle rotating folder can rotate and fold on the peripheral direction in relative to the lower rotating base; the bicycle rotating folder is stable and reliable in overall structure, and convenient to adjust.

Description

technical field [0001] The invention relates to the technical field of bicycles, in particular to a bicycle rotary folder. Background technique [0002] A bicycle, also known as a bicycle or bicycle, is usually a small land vehicle with two wheels.
