[detailed description of the invention]
The structure of the utility model embodiment child's bicycle as shown in Figures 1 to 9, comprises vehicle frame, front-wheel 1, trailing wheel 2 and vehicle seat 3, and vehicle frame comprises front-axle beam 4, front fork 5 and back vent 6.
There is a hinged seat rear end of front-axle beam 4, and vehicle seat 3 is arranged on the top of hinged seat, and for attractive in appearance and prevent the injury of internal mechanism to child, left guard shield 11 and right guard shield 12 spiral-locks are in the outside of hinged seat.
Hinged seat comprises the two blocks of side plates 401 in left and right, has a hinge hole 402 and the deep-slotted chip breaker 403 with a mountain font on side plate 401, and the inner arc side of deep-slotted chip breaker 403 has three groove 403a that hold locking shaft 10.Deep-slotted chip breaker 403 is positioned at the dead aft of side plate 401 hinge holes 402.
The front end of back vent 6 has an articulated joint, and articulated joint has a hinge hole 602 and locking axis hole 603, and locking axis hole 603 is prolate holes, the radial arrangement of the long axis hinge hole 602 of locking axis hole 603.The locking axis hole 603 of articulated joint is positioned at the dead aft of articulated joint hinge hole 402.
Release driving lever 7 comprises handle 701 and shift lever end 702, and there is a through hole 703 at the middle part of shift lever end 702, and the edge of shift lever end 702 has between 704, two arc-shaped protrusions 704 of two arc-shaped protrusions and forms a groove 705.
Articulated joint has the two blocks of side plates 601 in left and right, and the shift lever end 702 of release driving lever is clipped between the left side plate 601 of articulated joint, and articulated joint is clipped between the left side plate 401 of hinged seat.
Jointed shaft 8 is through hinge hole 402, the hinge hole 602 of articulated joint and the through hole 703 of shift lever end 702 of hinged seat, and the two ends of jointed shaft 8 are exposed at the outside of the two blocks of side plates 401 in hinged seat left and right.
Locking shaft 10 is through the deep-slotted chip breaker 403 on hinged seat side plate 401 and the locking axis hole 603 of articulated joint, and the two ends of locking shaft 10 are exposed at the outside of the two blocks of side plates 401 in hinged seat left and right.
