<p>A connecting tube structure of a bicycle includes: there is a transverse hand tube socket (52) at one end of a tube section (51). There is a vertical tube socket (55) at the other end of the tube section (51). The hand tube socket (52) is used for holding and locking a hand tube (60). The vertical tube socket (55) is used for holding and locking a fork tube (70). The hand tube socket (52) of the tube section (51) on both sides of the corresponding the handle tube (60) outside of the angle with a pair of convex ears (53,54), so that hand tube socket (52) right and left sides were like outward expansion;There is a convex outer edge of the rib at angle between the tube section (51)and the vertical fork tube socket, so that at the lower end of the vertical tube socket (55) was like outward expansion;. In addition to the present invention to facilitate the smooth control of the cable and pull it through the connecting tube, but also makes connecting the tube section (51) of tube (50) and the handle tube socket (52) or vertical tube socket (55) at it's both ends to increase structural strength between them. At the same time, increased hand tube socket (51) relative hand tube (60) surrounded the area, thereby increasing the strength of locking, but also further enhance hand tube (60) relative fork tube (70) the effect of the turning.</p> |
