A bicycle frame connecting structure is mainly composed of a seat cushion installation pipe (2), a main frame (1) of a tailstock (4) installed outside the seat cushion installation pipe (2), a fixing seat (5) and a rear wheel fork (9) installed at the rear end of the fixing seat (5). The bicycle frame is characterized in that a limiting step (10) is arranged at the upper end of the seat cushion mounting pipe (2), when the lower end of the seat cushion mounting pipe (2) penetrates through a vertical through hole (11) of a tailstock (4) at the rear end of the main frame (1) and a vertical through hole (12) of a fixed seat, the limiting step (10) at the upper end of the seat cushion mounting pipe (2) is buckled on a limiting platform (3) at the upper end of the tailstock (4), and the lower end of the seat cushion mounting pipe (2) is mounted on the fixed seat (5) quickly and conveniently. In addition, the structure is simple, parts can be modularly produced, the material cost is reduced, the weight of the whole vehicle is reduced, the productivity is improved, and the cost of the whole vehicle is reduced.
一种自行车车架连接结构,主要由座垫安装管(2)、安装在座垫安装管(2)外面尾座(4)的主车架(1)、固定座(5)、和安装在固定座(5)后端后轮叉(9)组成;其特征在于:由于座垫安装管(2)的上端设有限位台阶(10),当座垫安装管(2)下端穿过主车架(1)后端尾座(4)的竖立通孔(11)和固定座竖立通孔(12)时座垫安装管(2)上端的限位台阶(10)扣在尾座(4)上端的限位平台(3)上,座垫安装管(2)下端安装在固定座(5)上安装快捷方便。另外本发明还具有结构简单,零部件可以模块化生产,降低材料成本和减轻整车重量,提高产能降低整车成本等优点。
