The invention discloses a trolley balancing device, and relates to the technical field of trolleys. The trolley balancing device comprises a bottom frame, a trolley and a fixed block. The trolley comprises a bottom plate, and the top of the bottom frame is fixedly connected with the bottom of the bottom plate. A fixed groove is formed in the bottom of the bottom frame, and the bottom of the innerwall of the fixed groove is fixedly connected with a spline shaft. A connecting column is movably connected in the fixed groove, and the top end of the connecting column is fixedly connected with an inserting block. A spline hole matched with the spline shaft is formed in the inserting block, and through grooves are formed in the two sides of the bottom frame. One side of the inner wall of each through groove is rotationally connected with a lead screw through a bearing. According to the trolley balancing device, the balancing device can be conveniently demounted and mounted, and subsequent maintenance or replacement of the balancing device is convenient; meanwhile, when the device moves, good stability can be kept by arranging a sliding wheel and moving wheels, a clamping spring has elastic potential energy, shaking generated when the trolley moves can be automatically compensated for, and actual use needs are met.
Description
technical field [0001] The invention relates to the technical field of trolleys, in particular to a trolley balancing device.
