Quick-connection and quick-disassembly structure for longitudinal connection of multi-person bicycles

Abstract

The invention discloses a quick-connection and quick-disassembly structure for longitudinal connection of a multi-user bicycle. A yin quick-connection mechanism and a yang quick-connection mechanism of the structure are connected with a front wheel and a rear wheel of the bicycle respectively and rotate synchronously; a T-shaped groove is formed along the center line of a yin quick-connection disc, a left limiting sliding block and a right limiting sliding block are arranged at the two ends of the T-shaped groove respectively and move along arc-shaped sliding grooves, an elastic limiting top ball arranged at the bottom of the arc-shaped sliding groove controls the beginning and ending positions of the left limiting sliding block and the right limiting sliding block, and the left arc-shapedsliding block and the right arc-shaped sliding block drive the left limiting sliding block and the right limiting sliding block to move in the arc-shaped sliding grooves. a T-shaped boss is arrangedon the disc surface of a yang quick-connection disc; when the limiting sliding block at one end of the T-shaped groove of the front bicycle is opened, the T-shaped boss of the rear bicycle is insertedalong the opening end of the T-shaped groove to enable the limiting sliding block to reset, and quick connection between bicycles is achieved. The limiting sliding block is moved again, one end of the T-shaped groove is opened again, the T-shaped sliding block is moved out in the reverse direction, and rapid disassembly of the two vehicles is completed. By means of the structure, longitudinal rapid connection and disassembly of the single bicycle are achieved, and the connection reliability is improved.

Description

technical field [0001] The invention relates to the longitudinal connection of bicycles, in particular to a quick-connection and quick-disassembly structure for the longitudinal connection of multi-person bicycles. Background technique [0002] As the simplest and most convenient means of transportation, bicycles have always been widely used by people. Under the current environment of advocating green travel, bicycles still play an important role in solving the problem of the last mile of travel. [0003] With the development of the times, the bicycle service industry has gradually emerged, and personal short-distance travel tools represented by bicycles have gradually become popular. Breaking the traditional concept of cycling, developing and leading a new bicycle experience has become the focus of the bicycle industry. The emergence of multi-person bicycles such as tandem bicycles and three-person bicycles has added more riding fun to group travel, but the free switching b...

Problems solved by technology

The emergence of multi-person bicycles such as tandem bicycles and three-person bicycles has added more riding fun to group travel, but the free switching between multi-person bicycles and single-person bicycles has not been realized. Most of the tandem bicycles and three-person bicycles are fixed structures. Unable to achieve a variety of assembly combinations
