Claims

[Scope of utility model registration request]

In an automatic balancing balance that includes a pan holder 9 on which the weighing pan 2 can be mounted and a donkey pal mechanism 7 having a vertically movable rod 8 on a frame 24, there is a space between the pan holder 9 and the vertically movable rod 8. A limiter mechanism 21 is interposed in the limiter mechanism 2.
1 has one end fixed to the vertically movable rod 8, and the other end has a limiter spring 27 which transmits the acting force to the vertically movable rod while bending in response to an acting force, and the upper end thereof is connected to the plate holder 9. receives the acting force from the plate holder, and is locked to the vertically movable rod 8 so as to be able to slide up and down, and its lower end engages with the other end of the limiter spring 27 to transfer the acting force to the limiter spring. It includes a transmitting limiter 22 and a projecting piece 23 that projects from the lower end of the limiter 22 and comes into contact with the frame 24,
As a result, the limiter 22, which receives a force of the allowable limit value from the object to be measured via the plate support 9, can vertically move by a stroke corresponding to the allowable limit value against the upward biasing force from the limiter spring 27. The projecting piece 23 slides down relative to the moving rod 8.
A protection device for an automatic balance weighing machine, characterized in that the frame 24 is brought into contact with the frame 24. −
