Local pressure, meanwhile, prevent gap adjustment bar from falling.
In one embodiment, lock plate is included in the middle part of the gap adjustment bar, the lock plate is located at described first
Above through-hole, the lock plate limits the minimum altitude of the gap adjustment bar.
By setting lock plate, the maximum value of the deformation of weighing of electronic scale at work is on the one hand limited, on the other hand
Also gap adjustment bar is avoided to fall.
Preferably, the gap adjustment bar bottom further includes knob, and the diameter of the knob is more than the gap adjustment bar
The diameter at middle part.
Preferably, the electronic scale further includes：Master controller, input button, display module；The first of the master controller
Input terminal is connect with the weighing sensor, and the second input terminal of the master controller is with the input by key connection, the master
The third output terminal of controller is connect with the display module.
The beneficial effects of the utility model are：In Transportation Engineering, gap adjustment bar can be set as to higher position, dropped
Gap between low weighing sections bottom and pedestal, effective protection weighing sensor avoid the impact in Transportation Engineering from causing to weigh
Sensor degradation.Meanwhile in real work, it can be passed through between the adjusting of gap adjustment bar according to the range of sensor
Gap, to be adapted to the protection of the antioverloading of different range weighing sensors.
