第２項記載の上皿天びんの保護機構。[Claims for Utility Model Registration] (1) A sample plate is engaged above a movable column whose displacement direction is regulated by a parallel motion mechanism, and a lever engaged with the movable column applies a load to the sample plate. In a balance that measures the load acting on the sample pan by transmitting the load to the load sensor, a pan support shaft with the sample pan mounted on the top is disposed inside the movable column, and the load on the pan support shaft is The lower end is supported by a fulcrum provided on the movable column so that it can be tilted in any direction with respect to the axis of the movable column, and above the fulcrum, the countersunk shaft is connected to the movable column. A protection mechanism for a precision balance, comprising a spring and a stopper that comes into contact when the countershaft is tilted by a predetermined amount or more. (2) The countersunk shaft is slidably supported in the axial direction by the fulcrum, and the lower end of the countersunk shaft can protrude downward from the movable column, and a predetermined distance from the lower end of the countersunk shaft. A protection mechanism for a precision balance balance according to claim 1, characterized in that a stopper is disposed below to restrict downward displacement of the countershaft. (3) The above-mentioned utility model registration claim 1 or 2, characterized in that the spring is a rod-shaped spring fixed to the countersunk shaft in a direction perpendicular to its axial direction. Protection mechanism for dish balances.
