The diameter Relationship of thread fitting.By setting pole cap on the one hand to increase the contact area with sensor of gap adjustment bar, reduce
Local pressure, meanwhile, prevent gap adjustment bar from dropping.
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 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 drop.
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 connected with the weighing sensor, and the second input terminal of the master controller presses key connection, the master with the input
3rd output terminal of controller is connected with the display module.
The beneficial effects of the invention are as follows：In Transportation Engineering, gap adjustment bar can be arranged to higher position, reduce and claim
Gap between weight portion bottom and base, effectively protects weighing sensor, avoids the impact in Transportation Engineering from causing weighing and sensing
Device damages.Meanwhile in real work, gap can be adjusted by gap adjustment bar according to the range of sensor, with
Just it is adapted to the antioverloading protection of different range weighing sensors.

Embodiment
The invention will be further described with reference to the accompanying drawings and examples：
As shown in Figs. 1-5, in the first embodiment of the invention, there is provided a kind of electronics for including overload protecting mechanism of weighing
Scale, the electronic scale include：Base 101, plummer 106, weighing sensor 110；The weighing sensor 110 includes being used to send out
Give birth to the weighing sections 109 of deformation and for installing fixed mounting portion 107, the plummer 106 and the weighing sensor 110
Weighing sections 109 connects, and the mounting portion 107 of the weighing sensor 110 is installed on the base 101；
There are deformation gap between 109 bottom of weighing sections and the base 101；The base 101 is weighed with described
The corresponding region in 109 bottom of portion offers the first through hole for installing gap adjusting rod 108, the gap adjustment bar 108
Through the first through hole, the gap adjustment bar 108 and the first through hole thread fitting.
In Transportation Engineering, gap adjustment bar 108 can be arranged to higher position, reduce by 109 bottom of weighing sections and bottom
