Handrail Assembly and Manufacturing Method Therefor, Support Frame Structure, and Child Carrier

A method for manufacturing of a handrail assembly, the handrail assembly including a handrail body, comprising steps of:

• (1) providing a first protective layer, a second protective layer and a first adhesive layer, wherein the first adhesive layer is provided on a surface of the first protective layer in contact with the handrail body, the first adhesive layer made of a hot-melt material;
• (2) adhering and fixing the first protective layer and the second protective layer to form a base material layer having an integrated structure;
• (3) curling the base material layer into a protective sleeve matched with the handrail body, wherein the protective sleeve has a cylindrical structure, the first adhesive layer located at an inner side of the protective sleeve;
• (4) inserting the handrail body, which is matched with the protective sleeve, into the protective sleeve to form a handrail assembly blank;
• (5) baking the handrail assembly blank until the first adhesive layer is completely melted;
• and
• (6) cooling a baked handrail assembly blank to form a required handrail assembly.

A support frame structure, comprising:

• a front support assembly;
• a rear support assembly;
• a push rod assembly;
• a connecting assembly assembling and connecting the front support assembly, the rear support assembly and the push rod assembly;
• and
• a handrail assembly including a handrail body covered with a first protective layer having a flexible structure, the first protective layer covered with a second protective layer, the second protective layer shielding the first protective layer to prevent the first protective layer from being exposed to outside,
• wherein a connecting portion of the handrail assembly is detachably connected to the connecting assembly.
