The invention provides a tube (23) adapted to a support frame (200) of a child carriage (1). The tube (23) is a hollow structure. Two connecting segments (233) are formed at both ends of the tube (23), have identical structures, and are used for connection. A support segment (231) is formed between the two connecting segments (233) of the tube (23). A cross-sectional moment of inertia of the support segment (231) is larger than a cross-sectional moment of inertia of the connecting segment (233). The invention increases the cross-sectional moment of inertia of the support segment (231) to effectively improve the bending resistance and impact resistance of the tube (23) and ensure the stable support capability of the tube (23). Furthermore, the invention provides the support frame (200) with the tube (23) and the child carriage (1).
