The invention relates to the technical field of trolleys, and discloses a trolley folding mechanism which comprises a trolley body, a storage mechanism, a contraction mechanism and a damping mechanism, the storage mechanism is located on the left side of the trolley body, the contraction mechanism is located at the top end of the trolley body, and the damping mechanism is located at the bottom end of the trolley body. The storage mechanism comprises a connecting block, a clamping ring, a clamping rod, a torsion spring, a limiting handle, a hinge and a folding plate, and the folding plate is installed on the left side of the trolley body. According to the folding mechanism of the trolley, the storage mechanism is installed, a limiting handle is pulled, a clamping ring is taken out, at the moment, a folding plate is separated from the bottom of the trolley body, the folding plate is folded, one side of a hinge is overturned and folded along with the folding plate, the occupied space of the trolley body is reduced, and the trolley body can be stored conveniently; and the torsion spring facilitates movement of the limiting handle and drives the limiting handle to return to the original position, so that the limiting handle limits the clamping ring.

    本发明涉及手推车技术领域,且公开了一种手推车的折叠机构,包括手推车主体、收纳机构、收缩机构和减震机构,所述收纳机构位于手推车主体的左侧,所述收缩机构位于手推车主体的顶端,所述减震机构位于手推车主体的底端,所述收纳机构包括连接块、卡环、卡杆、扭转弹簧、限位把手、铰链和折叠板,所述折叠板安装于手推车主体的左侧。该手推车的折叠机构,安装了收纳机构,拉动限位把手,取出卡环,此时折叠板与手推车主体的底部分离,对折叠板进行折叠,铰链一侧跟随折叠板翻转折叠,手推车主体的占用空间减小,便于手推车主体进行收纳,扭转弹簧便于限位把手的活动且带动限位把手回归原位,使限位把手对卡环进行限位。
