The invention discloses a pipe fitting for a supporting frame of a child carrier. The pipe fitting is of a hollow structure, connecting sections which are of the same structure and used for connection are formed at the two ends of the pipe fitting, a supporting section is formed between the two connecting sections of the pipe fitting, and a first axial direction is formed in the vertical direction and a second axial direction is formed in the horizontal direction with the mass center of the supporting section as the perpendicular foot; the inertia moment in the first axial direction is larger than that in the second axial direction, and the sectional area of the connecting sections is the same as that of the supporting section; the pipe fitting can be connected with a standard joint in a matched mode, and the bending resistance and the impact resistance can be effectively improved on the premise that the weight is not increased. In addition, the invention discloses a folding supporting frame with the pipe fitting and a child carrier.
本发明公开了一种用于儿童载具之支撑架的管件,管件呈中空结构,管件的两端形成结构相同且用于连接的连接段,管件的两连接段之间形成支撑段,以支撑段的质心为垂足沿竖直方向形成第一轴向及沿水平方向形成第二轴向,第一轴向的惯性矩大于第二轴向的惯性矩,连接段的截面积与支撑段的截面积相同;上述管件能与标准的关节进行匹配连接,并且在不增加重量的前提下,还能有效提高抗弯曲和抗冲击能力;另,本发明还公开了一种具有上述管件的收折支撑架及儿童载具。
