Load cell having transport anti-drop mechanism, and electronic balance comprising same

Abstract

These disclosures provide a load cell having a transport anti-drop mechanism and an electronic balance including the load cell. The load cell includes a base, a core shaft, an elastic body, a sleeve, a limit pin, a weighing pan support, and a weighing pan connector. The base is provided with a mounting recess, the weighing pan support is provided with a through hole, and the sleeve passes through the through hole and extends into the mounting recess. The core shaft is arranged in the sleeve in a penetrating manner, the elastic body is mounted between the core shaft and the sleeve, the weighing pan connector is mounted at an end portion of the core shaft, the limit pin is mounted at the end of the core shaft and located outside the sleeve, the end of the sleeve is provided with a plurality of limit notches, and a limit baffle is provided on an inner wall surface of the mounting recess. The load cell can be switched between a non-transport protection state, an overload protection state, and a transport protection state, which improves the drop impact resistance during transport, and the force applied to delicate parts is controlled by the amount of compression of the elastic body and it will not exceed the yield strength of the delicate parts.
