The lifting pull basket comprises a fixing frame, a connecting rod set and a lifting frame with a basket body, the connecting rod set comprises a plurality of moment connecting rods and hinge connecting rods which are arranged in parallel, or the connecting rod set comprises a plurality of moment connecting rods which are arranged in parallel; the connecting rod set further comprises at least one elastic telescopic piece, one end of the elastic telescopic piece is hinged to the fixing frame, and the other end of the elastic telescopic piece is hinged to a mounting position arranged on the torque connecting rod. A movable moving part is arranged on the torque connecting rod, and at least one mounting position is arranged on the moving part. According to the lifting pull basket provided by the invention, the elastic telescopic pieces are utilized to generate balance torque for vertical movement of the lifting frame, and meanwhile, the hinging position of at least one elastic telescopic piece can be adjusted, so that the purpose of adjusting the balance torque in a large range is achieved by adjusting the length of a force arm, and the lifting pull basket can be matched with load torque more accurately and linearly during use; the adjusting mechanism is simple and reliable. When the lifting pull basket is used, labor is saved, operation is smooth, and the containing requirements of various objects are effectively met.
本发明公开了一种力臂可调的升降拉篮,包括固定架、连杆组和带有篮体的升降架,所述连杆组包括平行布置的多个力矩连杆和铰接连杆、或包括平行布置的多个力矩连杆;连杆组还包括至少一个弹性伸缩件,弹性伸缩件一端与固定架铰接、另一端与设于力矩连杆上的安装位铰接;所述力矩连杆上设有可移动的移动件,其中至少一个安装位设置在移动件上。本发明提供的升降拉篮利用弹性伸缩件产生对升降架上下运动的平衡力矩,同时至少有一个弹性伸缩件的铰接位置可调节,从而调节力臂长度的达到大范围调整平衡力矩的目的,使用时能够更精确、更线性的与载荷力矩匹配,调节机构简单可靠。升降拉篮使用时操作省力、顺滑,有效满足各类物品的收纳需求。
