One end of displacement sensor 9 is taper end.This kind setting can't change position of centre of gravity, after mounting, because center of gravity is located adjacent to position
The side of displacement sensor is also easy to produce deformation under long-time Gravitative Loads, and after becoming taper end, it is provided with variable cross-section, is eliminated
Rod component flexes deform the influence to displacement data under time Gravitative Loads.
The rod-shaped member that connector 10-3 is vertically arranged, the fixed company in one end of rod-shaped member and the bottom center of seat board 8
It connects, the other end of rod-shaped member is pressed on the end of lever 10-1.Lever 10-1 and connector after the installation of optimal selection at this time
One end present position of 10-3 connection is lower than another heavy end present position of lever 10-1, because lever passes through with bracket when in use
The components such as spacer pin carry out hingedly, being also easy to produce fit clearance, by way of connector 10-3 is pushed, compress, make in real time in this way
Always be in impaction state between lever and spacer pin, bracket, eliminate influence of the fit clearance to displacement data, lever again by
When to loading force position change, fit clearance will not have an impact the displacement difference of measurement.
The end of rod-shaped member is the cambered surface matched and curved surface with the end of lever 10-1.In this way when pushing, guarantee
Cooperation between the two will not be detached from.
A kind of force measuring method of vertical force measurement type bridge pad, to vertical force measurement type bridge pad described in claim 1
Upper seat load calibration loading force, and displacement sensor is read, obtains calibration loading force and displacement sensor shift value
Relational expression；According to the relational expression of calibration loading force and displacement sensor shift value, by being mounted on vertical force measurement type bridge branch
The shift value of displacement sensor on seat reversely obtains the vertical load force value on vertical force measurement type bridge pad.
