所述脚踏板5通过支臂连接在大齿盘上，所述前轮2设置小齿盘，大齿盘和小齿盘套连在同一齿轮链上，大齿盘转动一圈可以得到小齿盘转动数圈，小齿盘与前轮2同轴，则可以得到前轮2的较长位移。The foot pedal 5 is connected to the large toothed disc by an arm, the front wheel 2 is provided with a small toothed disc, the large toothed disc and the small toothed disc sleeve are connected on the same gear chain, and the large toothed disc is rotated one turn to obtain a small When the toothed disc rotates a few times and the small toothed disc is coaxial with the front wheel 2, a long displacement of the front wheel 2 can be obtained.
所述座椅活动轴13的轴套设置侧切面，轴体和钢片14之间设置弹簧15，转动座椅1活动轴13随之转动，当转动到侧切面位置时，刚片14卡进轴套侧切面内，无法继续转动，座椅的角度也随之被锁定，当更大外力旋转推动时，克服弹簧15的弹力阻力，刚片14继续压迫弹簧，弹簧15被进一步压缩，刚片14离开侧切面，座椅1又可以继续转动，直到另一个刚片14落入侧切面，此种侧切结构设计多个，转动座椅1时就可以得到不动角度的锁定，适合调整座椅1的舒适度。The sleeve of the seat movable shaft 13 is provided with a side cutting plane, and a spring 15 is disposed between the shaft body and the steel sheet 14. The rotating shaft 13 of the rotating seat 1 rotates accordingly. When the position is rotated to the side cutting plane, the rigid sheet 14 is stuck. In the side cut surface of the bushing, the rotation cannot be continued, and the angle of the seat is also locked. When the external force is rotated and pushed, against the elastic resistance of the spring 15, the rigid piece 14 continues to press the spring, and the spring 15 is further compressed. 14 leaving the side cut surface, the seat 1 can continue to rotate until the other rigid piece 14 falls into the side cut surface, such a side cut structure design is multiple, when the seat 1 is rotated, the fixed angle can be locked, suitable for adjusting the seat 1 comfort.
座椅1颈部设置后仰托架16，所述后仰托架16中空形成手部抓握端，当使用者后躺时，头部枕在后仰托架16上，后仰托架16巧妙形成的抓握端方便推车人辅助推车，整车折叠后也可作为拉手拖着前行，所述座椅颈部设置弹性颈托17，使用者后仰躺下时，弹性颈托17全方位的托住护住使用者后颈，颈托17的材质可以选择可塑性硅胶，因为颈托17为弹性，可以依照其颈部与后仰托架16的接触面形成稳定形状。 The neck of the seat 1 is provided with a backrest bracket 16, and the backrest bracket 16 is hollow to form a hand grip end. When the user lies back, the head rests on the back bracket 16 and the back bracket 16 The cleverly formed gripping end is convenient for the cart person to assist the stroller, and the whole cart can also be dragged forward as a handle after folding, the seat neck is provided with an elastic neck rest 17, and the elastic neck rest is placed when the user is lying back. 17 The omnidirectional support protects the user's back neck. The material of the neck rest 17 can be selected from plastic silicone. Because the neck rest 17 is elastic, it can form a stable shape according to the contact surface of the neck and the reclining bracket 16.
