An improved five way structure of the child car, the middle shaft of the child's car runs through the five pipe, the two bowls of the two bowls are installed respectively at both ends of the five pipe, and the two bowls sleeve is embedded in the two ends of the five pipe, and a bearing sleeve is fixed in each bowl type sleeve. The two ends of the shaft are penetrated after the two bearing sleeves and can be relative bearings. The shaft side is provided with a convex torus which is convenient for axial orientation, and a gasket and spring on the other side, which is convenient to limit the axis to the middle of the five pipe and prevent the axial sliding of the middle shaft. The five pipe port is fitted with a convex bar and a concave slot for the port of the bowl type sleeve, which is easy to install in the bowl type shaft sleeve in the five pass. At the same time, the tube can prevent the radial rotation. The bearing sleeve and the bowl type shaft sleeve are provided with the flange surface and the step surface which are convenient to install. The ends of the five ends of the pipe are flat with the flange face corresponding to the bearing sleeve and the end face of the corresponding bowl type shaft sleeve. The utility model has the advantages of convenient loading and unloading, low cost, and can meet the children's sliding and learning steps. Use.
【技术实现步骤摘要】
改进型童车五通结构
本技术涉及童车五通结构,特别涉及一种方便儿童学步、滑步操作的童车五通结构改进。
技术介绍
根据儿童不同年龄段、不同的用途,设计的儿童童车结构和功能也有很多不同:一种是儿童滑步车,就是两端安装踏板的中轴,转动固定于五通管(也可以通过轴承固定五通管),小孩双脚搁在踏板上后由看护人推着滑步车前进,这类车适合较年龄段小的儿童;另一种是儿童学步车,就是两端安装踏板的中轴,通过轴承固定于五通管,中轴一侧还安装有可驱动后轮的链条组件(通常后轮支架两侧还设有防滑倒的支撑脚),小孩可以脚踩踏板前进,这类车适合年龄段大的儿童,这样伴随小孩成长需要不同儿童童车,能否提供一种兼具滑步、学步功能,满足不同年龄段需要的五通管与中轴连接组件,成本低,又能自行装卸。
技术实现思路
为了弥补以上不足,本技术提供一种改进型童车五通结构,装卸方便,成本又低,可以满足儿童的滑步、学步用途。本技术的技术方案是这样实现:一种改进型童车五通结构,童车的中轴贯穿于五通管,该五通管两端分别安装两碗型轴套,该两碗型轴套嵌入式分别固定于该五通管两端通孔内;每个碗型轴套内还固定一轴承套,该中轴两端贯穿于该两轴承套后,能相对轴承套自由转动;该中轴一侧设有便于轴向定位的凸环面,而另一侧套有一垫圈及卡簧,便于将该中轴限定于该五通管中部,防止中轴轴向滑动。作为本技术的进一步改进,该五通管端口与碗型轴套端口分别对应设有凸条和凹槽,便于在碗型轴套安装于五通管的同时,防止径向转动。作为本技术的进一步改进,该轴承套与碗型轴套分别设有便于安装的法兰面和台阶面。作为本技术的进一步改进,在垫圈和卡簧之间设有一软性垫片 ...
