Abstract
The invention discloses an electronic balance with an internal calibrating weight structure. An internal calibrating weight, a jacking mechanism which can jack the internal calibrating weight upward along the vertical direction, and a jacking and driving device which can drive the jacking mechanism to lift along the vertical direction are arranged. Meanwhile, a supporting rod which can support the internal calibrating weight along the vertical direction is arranged on an upper bracket of a sensor. When the electronic balance is to be calibrated before use, the jacking and driving device drives the jacking mechanism to travel downward, the internal calibrating weight descends down till being supported on the supporting rod of the upper bracket, and the jacking mechanism and the internal calibrating weight maintain a certain gap along the vertical direction. After calibration, the jacking and driving device drives the jacking mechanism to travel upward, the jacking mechanism jacks the internal calibrating weight upward so that the internal calibrating weight is separated from the supporting rod, and the internal calibrating weight and the supporting rod maintain a certain gap along the vertical direction, thus, the electronic balance can be used to weigh. The internal calibrating weight of the electronic balance is simple in structure, the calibrating process is convenient and accessible, the cost is lower, and the weighing accuracy of the electronic balance is enhanced.
