[0019] ​​The utility model makes further detailed description below combining with the drawings. In the description of the utility model, it is understood that the orientation words such as "up, down" and "top, bottom" and the like indicated orientation or position relation is usually based on the orientation or position relation shown in the drawing, only for the convenience of describing the utility model and simplifying the description, under the condition of not making opposite statement, these orientation words do not indicate and imply the device or element must have a particular orientation or with a particular orientation structure and operation, therefore can not be understood as the limitation to the protection scope of the utility model;The orientation words "inner, outer" refer to the inner and outer of the contour of each component itself.

[0020] As shown in Figures 1-4 An aluminum profile structure for child car body, comprising a profile body 1, the profile body is hollowly arranged, two inner vertical ribs 2 are fixedly installed in the profile body and oppositely arranged, two upper horizontal ribs 3 and two lower horizontal ribs 4 are fixedly installed between the two inner vertical ribs, the two upper horizontal ribs are spaced apart, the two lower horizontal ribs are spaced apart, and two spaced apart longitudinal ribs 5 are fixedly installed between adjacent upper horizontal ribs and lower horizontal ribs;

[0021] The upper cavity for placing the nut 6 is formed between the two inner vertical ribs and the two upper horizontal ribs, and the lower cavity for placing the nut is formed between the two inner vertical ribs and the two lower horizontal ribs, the nut is a hexagonal nut, and the two sides of the nut can be slidably attached to the inner vertical ribs, the profile body, the upper horizontal rib and the lower horizontal rib are oppositely and throughly provided with a through hole 8 allowing the bolt 7 to pass through, and the two longitudinal ribs are arranged on both sides of the through hole.
