Description of drawings
Fig. 1 is structure of the present utility model and user mode synoptic diagram;
Fig. 2 is another kind of user mode figure of the present utility model.
Mark is as follows among the figure: high precision digital display meter 1, frame 2, proving ring 3, lifting jack 4, check-out console 5, interface 6, high-precision pressure sensor 7, stressed plate 8, electronic scale sensor 9, electronic scale converter 10, high precision standard indicator gauge 11.
Embodiment
Fig. 1 shows that the utility model is made up of frame 2, stressed plate 8, check-out console 5, high-precision pressure sensor 7, high precision digital display meter 1, lifting jack 4.
Stressed plate 8 is two, be fixedly mounted on the two ends up and down of frame 2 respectively, high precision digital display meter 1 is installed in the top of the stressed plate 8 on frame 2 tops, high-precision pressure sensor 7 is installed on the stressed plate 8 of frame 2 bottoms, and the DOL Data Output Line of high-precision pressure sensor 7 is connected with high precision digital display meter 1 by interface 6.
Check-out console 5 be placed on high-precision pressure sensor 7 above, there is the slip guide hole check-out console 5 both sides, the slip guide hole is enclosed within on the column of frame 2, can slide up and down along frame 2 columns.
Fig. 2 shows that all right detected electrons weigh sensor 9 of the utility model is placed on lifting jack 4 tops with electronic scale sensor 9, and electronic scale sensor 9 is connected with electronic scale converter 10, high precision standard indicator gauge 11 successively.
In the utility model, part of detecting is made up of high precision digital display meter 1, high-precision pressure sensor 7 and check-out console 5, and the pressure-loaded part is made of lifting jack, and the power transmitting portions is by formed by checking device and stressed plate.
The utility model is when verification, and lifting jack 4 reinforcings are risen, and check-out console 5 is subjected to acting force and moves down, and by check-out console 5 acting force is passed to high-precision pressure sensor 7; The acting force of lifting jack 4 is passed to detected proving ring 3 simultaneously, according to Newton third law as can be known, acting force and reacting force equal and opposite in direction, direction is opposite, the size that proving ring 3 is stressed and the stressed equal and opposite in direction of high-precision pressure sensor 7, so the stressed size of proving ring 3 shows by high precision digital display meter 1.The numerical value that numerical value that high precision digital display meter 1 shows above and proving ring 3 show itself compares, and can identify the precision of proving ring 3.
Verification to electronic scale sensor 9 is same principle, what high precision digital display meter 1 showed is the pressure of lifting jack 4 reality to electronic scale sensor 9, electronic scale sensor 9 is the pressure that electronic scale sensor 9 itself records by the numerical value that electronic scale converter 10, high precision standard indicator gauge 11 show, above-mentioned two data are compared the precision that just can know electronic scale sensor 9.
