Background technology
Existing hanging ring type sensor, is mainly used for the fields such as electric power and building, generally using plate ring structure and
Pole structure.The hanging ring type sensor of existing plate ring structure and pole structure, usually portion sets one to answer in the sensor
Becoming area, the conduction of stress has some setbacks, and has conflict in certain field installation dimensions the reason of because of strain structure itself, meanwhile,
Power industry, old-fashioned link pulling force precision can it is very poor only 1% or so, and transducer range be difficult do it is small.
Utility model content
The purpose of this utility model is to provide a kind of pole structure link sensors easy to install, high certainty of measurement.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of link sensor of pole structure including elastomer, is respectively connected on the upper and lower both sides side wall of elastomer
Arc link；
It is set in the middle part of the elastomer there are two opposite round strain slot, described strain in slot posts foil gauge；
Bar-shaped trough is provided between two opposite strain slots.
Further, elastomer side side wall be equipped with fixed interface, the fixed interface using screw thread, grafting or
Snap fit is fixed.
The beneficial effects of the utility model：The link sensor of pole structure provided by the invention, changes existing link
Strain regions are become both sides by the structure of formula sensor from centre, solve occupancy of the strain regions to installation space, can be with during use
Selection measures the foil gauge resistance change in any strain slot, calculates pulling force size or measure simultaneously that sensor is subject to
Foil gauge resistance change in two strain slots, synthesis obtain the pulling force size that sensor is subject to, solve existing hanging ring type
Portion sets a strain regions to sensor in the sensor, the problem of conduction of stress is caused to have some setbacks, and greatly improves the essence of sensor
Degree, can make small-range sensor.
Description of the drawings
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.

" in ", " length ", " interior ", indicating positions or the position relationship such as " surrounding ", be for only for ease of description the utility model and simplification
Description rather than instruction imply that signified component or element must have specific orientation, with specific azimuth configuration and behaviour
Make, therefore it is not intended that limitation to the utility model.
As shown in Figs. 1-2, the utility model provides a kind of link sensor of pole structure, including rectangular elastomer 1,
Arc link 2 is respectively connected on 1 upper and lower both sides side wall of elastomer, link 2 is used to connect the hook in test system, utilizes bullet
Property body 1 by power when the deformation that occurs, measure the pulling force size for being added in 1 both ends of elastomer.
1 middle part of elastomer is set there are two opposite round strain slot 3, is strained in slot 3 and is posted foil gauge, solves strain regions
To the occupancy of installation space.Elastomer 1 generates change under the effect of both ends under tension, to the foil gauge in two strain slots 3
Shape, during foil gauge stress deformation, by acquiring its resistance change and linearly calculating the pulling force that sensor is subject to sensing amount
Size.
Bar-shaped trough 4 is provided between two opposite strain slots 3, ensures that two strain being more uniformly stressed for slot 3, work
When, can select to measure the foil gauge resistance change in any strain slot 3, calculate pulling force size that elastomer 1 is subject to or
The foil gauge resistance change in two strain slots 3 is measured simultaneously, and synthesis obtains the pulling force size that elastomer 1 is subject to, solves
The problem of existing hanging ring type sensor sets a strain regions, the conduction of stress is caused to have some setbacks at 1 middle part of elastomer, greatly improves
The precision of sensor can make small-range sensor.
1 side side wall of elastomer is equipped with fixed interface 5, and for sensor to be fixedly mounted on corresponding position, fixation connects
Mouth 5 can be used screw thread, grafting or snap fit and fix, during actual use, can fixed interface 5 be processed according to particular use.
The link sensor of pole structure provided by the invention changes the structure of existing hanging ring type sensor, strain
Area becomes both sides from centre, solves occupancy of the strain regions to installation space, and when use can select to measure in any strain slot
Foil gauge resistance change, calculate pulling force size that sensor is subject to or measure foil gauges in two strain slots simultaneously
Resistance change, synthesis obtain the pulling force size that sensor is subject to, solve existing hanging ring type sensor and set in portion in the sensor
The problem of putting a strain regions, the conduction of stress is caused to have some setbacks greatly improves the precision of sensor, can make small-range sensor.
In the description of this specification, the description of reference term " one embodiment ", " example ", " specific example " etc. means
