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 plate ring 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 plate ring structure, including sensor body, on the upper and lower both sides side wall of sensor body
Two opposite screw holes of hand of spiral are had, two screw holes connect hanging ring or suspension hook by screw respectively；
It is set in the middle part of the sensor body there are two opposite round strain slot, described strain in slot posts foil gauge；
Bar-shaped trough is provided between two opposite strain slots, the screw hole is mutually communicated with bar-shaped trough.
Further, the strain slot upper and lower both sides are respectively equipped with the first opening and the second opening, first opening and
Second openings direction in strain slot side on the contrary, form S types force area.
The beneficial effects of the utility model：The link sensor of plate ring 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.
Fig. 1 is the stereogram of the utility model.
Fig. 2 is the front view of the utility model.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without creative efforts
The all other embodiment obtained, shall fall within the protection scope of the present invention.
In the description of the present invention, it is to be appreciated that term " trepanning ", " on ", " under ", " thickness ", " top ",
" 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 plate ring structure, including sensor body 1,
Two opposite screw holes 2 of hand of spiral are had on 1 upper and lower both sides side wall of sensor body, two screw holes 2 pass through silk respectively
Bar connects hanging ring or suspension hook, and hanging ring or suspension hook are used to the hook in connection test system, during using sensor body 1 by power
The deformation of generation measures the pulling force size for being added in 1 both ends of sensor body.
1 middle part of sensor body is set there are two opposite round strain slot 3, is strained in slot 3 and is posted foil gauge, solving should
Become occupancy of the area to installation space.Sensor body 1 is under the effect of both ends under tension, to the foil gauge in two strain slots 3
It is deformed, during foil gauge stress deformation, by acquiring its resistance change and linearly calculating sensor sheet with sensing amount
The pulling force size that body 1 is subject to.
Bar-shaped trough 4 is provided between two opposite strain slots 3, screw hole 2 is mutually communicated with bar-shaped trough 4, ensures two strains
Slot 3 is more uniformly stressed, and during work, can be selected to measure the foil gauge resistance change in any strain slot 3, be calculated biography
The pulling force size or measure two foil gauge resistance changes strained in slot 3 simultaneously that sensor ontology 1 is subject to, synthesis obtains biography
The pulling force size that sensor ontology 1 is subject to solves existing hanging ring type sensor in 1 one strain of middle part setting of sensor body
Area, greatly improves the precision of sensor, can make small-range sensor the problem of conduction of stress is caused to have some setbacks.
3 upper and lower both sides of strain slot are respectively equipped with the first opening 5 and the second opening 6, wherein, the first opening 5 and the second opening
6 opening directions make the stress of strain slot 3 more collect neutralization uniformly, improve and pass on the contrary, in 3 side of strain slot formation S types force area
The precision of sensor.
The link sensor of plate ring 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.
