Abstract

The invention relates to a bicycle vertical tube device capable of being rotationally folded. The bicycle vertical tube device comprises a vertical tube, a connecting base, a rod piece unit and a quick release unit, wherein the top of the vertical tube is tapered and forms a plurality of propping surfaces; the inner wall surface of the groove of the connecting base is propped against the propping surfaces; rod piece unit axially penetrates through and is fixed in the vertical tube; the quick release unit is arranged on the connecting base; the rotation of the pivot of the quick lease unit is adopted to ensure that the connecting base is quickly clamped with or released from the rod piece unit, so that the bicycle vertical tube has functions of stable positioning, quick rotating folding and the like. The bicycle vertical tube device is simple in the integral structure and quick and convenient in the positioning mode.

Description

technical field [0001] The invention relates to a component of a bicycle, in particular to a rotatable and retractable bicycle standpipe device. Background technique [0002] The bicycle standpipe device that rotates and folds in the prior art includes a standpipe, a connecting seat, a rod unit, a quick release unit and a safety unit; There is a chamfered end surface; the connecting seat is covered on the top of the standpipe and has a handle hole for the bicycle handlebar to be fixed; the rod unit is axially fixed on the standpipe and is provided with a connecting rod and fasteners, fasteners It is screwed on the bottom end of the connecting rod and pressed against the chamfered end face of the riser.
