Specific embodiment
The embodiment of the utility model is described in further detail below in conjunction with attached drawing.
Ginseng is seen figure 1 and figure 2, and the utility model embodiment provides a kind of Suo Li for oblique cord cable force measurement and senses
Device, including limit part, pressure part and display portion.Limit part includes supporting rod 1 and limiting device：Two are equipped with
Limiting device be individually fixed in one end of supporting rod 1,1 shape of supporting rod is thick between the detail of both ends, the supporting rod 1 so designed
It can bear the power of bigger.Pressure part includes pressure bar 2, gripping mechanism 20 and disk 21, and pressure bar 2 is spiral shell with supporting rod 1
Line connects, and the bar 2 that presses, through supporting rod 1, pressure bar 2 is fixed with gripping mechanism 20 and equipped with pressure close to one end of limiting device
Power sensing device, the other end are equipped with disk 21.One end that gripping mechanism 20 is fixed in pressure bar 2 is equipped with pressure sensitive device, applies
Compression bar 2 and 1 link position of supporting rod are equipped with screw thread counter.User's rotating circular disk 21 drives pressure bar 2, due to the bar 2 that presses
With supporting rod 1 to be threadedly coupled, with the rotation of pressure bar 2, pressure bar 2 carries out displacement with respect to supporting rod 1.When need measure bridge
During the pulling force of a certain position of rope, two limiting devices are separately positioned on the bridge rope of the position both sides, the card to press on bar 2
Tight device 20 will be stuck in Qiao Suoshang.Rotating circular disk 21, disk 21 drive pressure bar 2 to rotate, since pressure bar 2 and supporting rod 1 are
