Abstract
The utility model provides a counterbalance in improved structure, which comprises a pedestal, a beam, a hanger, a pair of tray frames, a pair of trays, a pair of balance nuts, a pointer, a scaleplate, a scale, and a sliding poise. Both ends of the beam are articulated with the hanger through knife-edge beams; the lower end of the hanger is provided with an upright corbel piece; the pair of tray frames are fixed on the hanger on both ends of the beam; the pair of trays are arranged on the pair of tray frames respectively; the pair of the balance nuts are arranged on both ends of the beam; the pointer is arranged in the middle of the beam; the scaleplate is arranged on the pedestal; the scale is arranged in front of the middle of the beam; the sliding poise can be arranged on the scale in a slip way. The counterbalance in improved structure is characterized in that the counterbalance further comprises a pair of spring leaves fixed on the pedestal under the beam. The counterbalance has the advantages that the swing frequency of the beam is reduced through the pair of spring leaves arranged symmetrically in the horizontal direction so that the values can be read accurately at fixed points, and the weighing time is reduced.
