一种可折叠童车车架
摘要：
本发明公开了一种可折叠童车车架，包括前脚杆、后脚杆、座椅支撑杆、多级可伸缩手推杆以及折叠关节；折叠关节包含前脚杆关节块、后脚杆关节块、座椅杆关节块、手推杆关节块以及中心轴；前脚杆关节块和座椅杆关节块与中心轴固定连接，后脚杆关节块可转动地设置在中心轴上，手推杆关节块可转动地设置在中心轴上，中心轴上转动连接有可同时锁住后脚杆关节块、座椅杆关节块和手推杆关节块的卡锁组件，中心轴上还设有驱动卡锁组件动作解锁的解锁推杆；当推杆解锁装置解锁后，二级伸缩杆缩进一级伸缩杆内，进而驱动解锁推杆带动卡锁组件动作而实现对后脚杆关节块、座椅杆关节块和手推杆关节块解锁；具有结构简单、折叠步骤少、制造成本低的优点。
摘要（英）：

The invention discloses a foldable child carriage frame which comprises front foot rods, rear foot rods, seat supporting rods, a multi-grade telescopic hand pushing rod and folding joints. The folding joints comprise front foot rod joint blocks, rear foot rod joint blocks, seat rod joint blocks, hand pushing rod joint blocks and a central shaft; each front foot rod joint block and each seat rod joint block are fixedly connected with the central shaft, each rear foot rod joint block is rotatably arranged on the central shaft, each hand pushing rod joint block is rotatably arranged on the central shaft, a clamping and locking assembly capable of simultaneously locking each rear foot rod joint block, each seat rod joint block and each hand pushing rod joint block is rotatably connected to the central shaft, and the central shaft is further provided with an unlocking pushing rod for driving the unlocking operation of the clamping and locking assembly; and after unlocking is conducted by the pushing rod unlocking device, second-grade telescopic rods are retracted into first-grade telescopic rods, and then the unlocking pushing rod is driven to drive the clamping and locking assembly to operate, and unlocking of the rear foot rod joint blocks, the seat rod joint blocks and the hand pushing rod joint blocks is realized. The foldable child carriage frame has the advantages of being simple in structure, few in folding step, and low in manufacturing cost.
