Abstract:
A frame and a trolley. The frame comprises a central connector (310), wherein the central connector (310) is oppositely connected to bottom frame transverse pipes (320) in the direction of side frame bodies (100), one end of each bottom frame transverse pipe (320) is rotatably connected to the central connector (310), and the other end of the bottom frame transverse pipe is rotatably connected to a side frame body (100); swing pipe connectors (330), wherein the swing pipe connectors (330) are arranged in the direction in which the central connector (310) faces first folding assemblies (200); first swing pipes (340), wherein one end of each first swing pipe (340) is rotatably connected to the central connector (310), and the other end of the first swing pipe is rotatably connected to the swing pipe connector (330); and second swing pipes (350) arranged by an angle, wherein one end of each second swing pipe (350) is rotatably connected to the swing pipe connector (330), and the other end of the second swing pipe is rotatably connected to a side vertical pipe (110). By means of the cooperation of this structure, the bottom frame transverse pipes (320) can be directly and rotatably connected to the side frame bodies (100), and compared with other connecting manners, the stability of the structure is greatly improved, and the load upper limit is increased. Moreover, a user can obviously feel that the folding is more convenient when in use.
