Embodiment Construction

[0017] Figure 2 ~ Figure 3 The composition of the preferred embodiment of the present invention is shown. The locking device of the telescopic sleeve includes a sleeve 7, the upper port of the sleeve is provided with a guide groove 12 along the axial direction of the wall, and the insertion tube 1 that is inserted into the sleeve 7 and can slide relatively , the beam ring clamp 4 that is set on the outer circle of the upper port of the casing 7, and the eccentric locking handle 3 that is connected to the opening end of the beam ring clamp 4 . In this embodiment, the insertion tube 1 and the clamp 4 are made of extruded profiles. A planar structure 8 is arranged on the outer wall of the insertion tube 1 along the axial direction, and a limiting block 9 is arranged on the inner wall of the clamp 4 . The limit block is a limit plane towards the center of the beam clamp, and the limit plane fits with the plane structure 8 on the outer wall of the insertion tube 1. The limit blo...

Abstract

The invention discloses a locking device for a vertically telescopic sleeve that can be used for a bicycle handlebar. A beam clamp on the outer circle of the upper port of the pipe, and an eccentric locking handle connected to the open end of the beam clamp. The outer wall of the insertion tube is provided with a planar structure along the axial direction; the inner wall of the clamp is provided with a limit block, and the limit block is a limit plane facing the center of the clamp, and the limit plane is connected to the outside of the insertion tube. The planar structure of the circular wall surface fits together, and the limit block is connected with the inner circular wall surface of the clamp by a guide piece, and the guide piece is clamped in the guide groove of the casing. The limiting surface where the limiting block and the insertion tube fit together is set in a planar structure, which can effectively limit the relative rotation of the insertion tube. The invention effectively overcomes the defect of unreliable connection in the prior art.

Description

technical field [0001] The invention relates to a mechanical connection mechanism, in particular to a locking device for a vertical telescopic sleeve used for folding a handlebar of a bicycle. Background technique [0002] Folding bicycles are favored by consumers for their fast folding or unfolding features. When the bicycle is folded, its volume becomes smaller, which greatly facilitates transportation and storage; after unfolding, it can be used safely, which is convenient for people to exercise or travel. The standpipe of the handlebar and the standpipe of the front fork are installed on the front end of the frame of the bicycle, and the standpipe is inserted into the standpipe and the axial height is adjusted by relative sliding. Generally, after the relative position of the standpipe and the standpipe is adjusted, the two are fixedly connected by a locking device, so that the two can neither slide axially relative to each other nor rotate circumferentially relative to...
