The frame comprises a middle connecting piece, the middle connecting piece is oppositely connected with a bottom frame transverse pipe in the direction of a side frame body, one end of the bottom frame transverse pipe is rotationally connected with the middle connecting piece, and the other end of the bottom frame transverse pipe is rotationally connected to the side frame body; the swing pipe connecting piece is arranged on the middle connecting piece and faces the direction of the first folding assembly; one end of the first swing pipe is rotationally connected with the middle connecting piece, and the other end of the first swing pipe is rotationally connected with the first swing pipe connecting piece; one end of the second swing pipe is rotationally connected with the first swing pipe connecting piece, and the other end of the second swing pipe is rotationally connected with the side vertical pipe. Through cooperation of the structure, the bottom frame transverse pipes can be directly and rotationally connected with the side frame bodies, compared with other connecting modes, the structural stability is greatly improved, the loading upper limit is improved, and a user can obviously feel that folding is more convenient during use.
本申请公开了一种车架和推车,包括中间连接件,中间连接件在侧框架体方向相对连接有底框横管,底框横管的一端与中间连接件转动连接,另一端转动连接于侧框架体;摆管连接件,摆管连接件设置于中间连接件朝向第一收拢组件方向;第一摆管,第一摆管的一端与中间连接件转动连接,另一端与第一摆管连接件转动连接;呈角度设置的第二摆管,第二摆管一端与第一摆管连接件转动连接,另一端与侧边竖管转动连接。本发明通过此结构的配合,使得底框横管能够实现与侧框架体的直接转动连接,相对于其他连接方式,大大提升了结构的稳定性,提升了装载上限,且使用人在使用时能够明显感觉收拢更加方便。
