Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] Figure 1 to Figure 6 As shown, the bicycle standpipe folding mechanism includes an upper standpipe 1, a lower standpipe 2, a folding guide piece 3, a locking hoop 4, a locking handle assembly 5, a fixing screw 6, and a set screw 7, and the locking hoop 4 is set on the lower port of the upper standpipe 1, and a pipe groove 1a is opened at the lower port of the upper standpipe 1. When the upper standpipe 1 is locked or loosened by the locking collar 4, the upper standpipe 1 Through the deformation of the tube groove 1a, there is a corresponding tightening or rebound effect. The through holes 4b in the extensions at both ends of the locking collar 4 pass through the fastening pin 51 of the locking handle assembly 5. The fastening pin 51 runs through a pin shaft 52, and the pin shaft 52 is pinned to a locking handle 53 with a rotating ecc...

Abstract

A folding structure for the vertical tube of bicycle is composed of upper vertical tube with a slot and a locking hoop having two through holes at its both ends, lower vertical tube, locking handle module with a fastening pin and its sleeve and a locking handle with eccentric structure, folding guide plate with symmetrical two screw holes and symmetrical two guide holes, and locating and fixing screws.

Description

technical field [0001] The invention relates to the application field of folding bicycles, in particular to a bicycle standpipe folding structure, which is suitable for manpower and electric bicycles. Background technique [0002] At present, the standpipe folders of most products in the folding bicycle market use a simple handle with claws to fold and open the entire standpipe through an elliptical movement, and are held by a plastic safety hook. The handle prevents the handle from bouncing away from the external force after it is locked. This is simple and convenient, but the locked quick-lock handle may be shaken by vibration and shaking during riding. The resulting force will cause the deformation of the place where the upper fold is stressed to gradually lose its effect, which will have a great impact on the safety of the user and the use time of the bicycle. [0003] The existing newly developed standpipe folding structure usually uses a folding seat to connect the up...
