Title: COLLAPSIBLE CONTAINER WITH BALANCING DEVICE
Abstract:
A collapsible container with a balancing device, comprising a bottom frame (6) and an end bracket (4) provided at two ends of the bottom frame (6). The balancing device comprises a balancing spring securing base (61), a balancing spring pulling arm (43), and a balancing spring (5). The balancing spring securing base (61) is provided on the bottom frame (6). The balancing spring pulling arm (43) is connected to a portion, proximal to a rotating shaft, of a movable hinge (42). The balancing spring pulling arm (43) is provided with a balancing spring pulling arm hole (431). One end of the balancing spring (5) is connected to the balancing spring securing base (61). A second end of the balancing spring (5) is connected, via the balancing spring pulling arm hole (431), to the balancing spring pulling arm (43). When the end bracket (4) of the collapsible container collapses or folds, the balancing spring pulling arm (43) can actuate extension or compression of the balancing spring (5). A reaction force generated by the balancing spring (5) can act, via the balancing spring pulling arm (43), upon the end bracket (4) to generate balance supporting torque, offsetting gravitational torque of the end bracket (4), thereby realizing the objective of balancing the end bracket (4) of the collapsible container.
