详述该折叠式婴童推车收合过程: Describe the folding process of the folding baby stroller in detail:
首先,按下二道锁按键,旋转旋转件,旋转件内的斜面推动滑块在导槽中滑动,此时,滑块拉动第一拉线。 First, press the secondary lock button, rotate the rotary member, the inclined plane inside the rotary member pushes the slider to slide in the guide groove, and at this time, the slider pulls the first pull wire.
其次,第一拉线拉动关节锁块扳手,关节锁块扳手与关节锁块在彼此的限位斜面作用下迫使关节锁块挤压复位弹簧向容置槽活动,关节锁块扳手通过限位斜面克服复位弹簧的力量顶开关节锁块,使关节锁块上的凸条脱离关节拨片上的限位孔,上手把关节与下手把关节可相对旋转,并通过支撑连接铁片上的弧槽进行旋转限位,从而收合手把管和前脚管进行收合,如图7所示。 Secondly, the first pull wire pulls the joint lock block wrench, and the joint lock block wrench and the joint lock block force the joint lock block to squeeze the return spring to move toward the accommodating groove under the action of each other's limit slope, and the joint lock block wrench overcomes the problem through the limit slope. The power of the return spring pushes the joint lock block, so that the convex strip on the joint lock block is separated from the limit hole on the joint paddle. The upper handle joint and the lower handle joint can rotate relative to each other, and the rotation is limited by the arc groove on the support connecting iron piece. position, so that the handlebar tube and the front leg tube are folded together, as shown in Figure 7.
其次,当该关节锁块在旋转的同时带动第二拉线拉动前脚关节上的锁销在拉力作用下,锁销克服锁销复位弹簧同前脚连接加强铁片中的槽分离,这样前轮组和前脚管可以绕轴线旋转,从而收合前脚管和前轮组件,如图8所示。 Secondly, when this joint lock block drives the second backguy wire to pull the lock pin on the front foot joint when rotating, under tension, the lock pin overcomes the lock pin back-moving spring and connects the slot in the reinforced iron plate with the front foot to separate, so that the front wheel group and The front leg tube can rotate around the axis, so as to fold the front leg tube and the front wheel assembly, as shown in FIG. 8 .
最后,收合支撑管、扶手连接铁片、前扶手、后脚管、前脚管、菜篮管以及后轮组,过程如图7-图9所示。 Finally, fold the support tube, armrest connecting iron sheet, front armrest, rear leg tube, front leg tube, vegetable basket tube and rear wheel set, the process is shown in Figure 7-9.
本实用新型的设计重点在于:该折叠式婴童推车通过设置有单手旋转收合机构,只需单手操作即可收合手把管和前脚管,同时收合前轮组件,进而收合支撑管、扶手连接铁片、前扶手、后脚管、前脚管、菜篮管以及后轮组;结构设计简单、巧妙,使用极为方便,且易于组装生产,极具市场推广价值。 The key point of the design of the utility model is that the foldable baby stroller is equipped with a one-handed rotating and closing mechanism, and only one-hand operation is required to close the handle tube and the front leg tube, and at the same time close the front wheel assembly, and then close the Combined support tube, armrest connecting iron sheet, front armrest, rear leg tube, front leg tube, vegetable basket tube and rear wheel set; the structure design is simple and ingenious, very convenient to use, easy to assemble and produce, and has great market promotion value.
