Quick-to-extend-and-contract rotating handlebar

Abstract

A quick-to-extend-and-contract rotating handlebar comprises a left handlebar, a right handlebar, an upper lock member, a lower lock member, two positioning rings and an inner extending pipe. A left upper lock member is composed of an upper clamping member and an upper quick release, and the upper quick release is mounted in a transverse penetrating hole shared by a left convex piece, a convex block and a right convex piece of the upper clamping member; each of the left handlebar and the right handlebar is in socketed connection with one positioning ring, and then the left handlebar and the right handlebar are penetratingly arranged in longitudinal round holes at left and right ends of the upper clamping member; the upper quick release can tighten a slotting round hole at the left end and a slotting round hole at the right end of the upper clamping member; the lower lock member is composed of a lower clamping member and a lower quick release, the lower quick release is mounted in a transverse penetrating hole shared by a left convex piece, a convex block and a right convex piece of the lower clamping member, the left handlebar and the right handlebar are penetratingly arranged in longitudinal round holes at left and right ends of the front portion of the lower clamping member, and two bolts are respectively screwed into threaded holes at the bottom ends of the left handlebar and the right handlebar respectively; the lower quick release can tighten a slotting round hole at the left end and a slotting round hole at the right end of the lower clamping member.

Description

technical field [0001] The invention relates to a handlebar of a folding bicycle, in particular to a quick telescopic handlebar which can be expanded and rotated. Background technique [0002] Folding bicycle handlebars are currently available on the market, but there is a problem that the folding speed is not fast or the folding effect is not ideal. Contents of the invention [0003] The object of the present invention is to provide a quick telescopic handle that can be stretched and rotated, and the folding speed is fast, and the effect is good after folding or unfolding. The object of the present invention is achieved in this way; the quick telescopic handle includes a left hand handle, a right hand handle, an upper lock, a lower lock, two positioning rings and an inner extension tube, and it is characterized in that the left hand handle and the right hand handle are made of a round tube The upper end of the handlebar is bent at a right angle. There are threaded holes ...
