Technical field
The utility model relates to sensor technical field, particularly a kind of square shape pull pressure sensor.
Background technology
Weighing and force-measuring transducer is actually a kind of device quality signal being changed into measurable electric signal and export; by one or more can at the elastic body of stressed rear generation deformation; with the bridge diagram (as Wheatstone bridge) that the resistance strain gage responding to this deformation quantity forms, and resistance strain gage fixedly can be pasted onto the three parts compositions such as the fluid sealant of bonding agent and the protection electronic circuit that elastic body also can conduct dependent variable.
Pull pressure sensor is the large classification of one in weighing and force-measuring transducer, and its shape mainly contains S type and pillar.Wherein, for S type pull pressure sensor, its primary structure comprises sensor main body, sensor outer housing and signal wire, and sensor main external body is provided with sensor outer housing, and sensor outer housing is connected with signal wire.Have transverse concave groove on top, long limit, the right side of sensor main body, bottom, long limit, left side has horizontal groove, and form " S " type structure thus, this " S " type structure is that time processing forms.On sensor main body between upper and lower two grooves, have the round through hole be interconnected along the direction that main body is high, through hole is symmetrical along the vertical axis of sensor main body, all posts foil gauge in through hole both sides.Have upper screwed hole and lower threaded hole at sensor main body upper surface and lower surface, and upper screwed hole communicates with upper groove, lower threaded hole communicates with low groove.Upper screwed hole is used for connecting the parts making force acting on transducer, and lower threaded hole is used for being connected and fixed testee.
The foil gauge of the sensor and other annexes are all located at sensor main external body, add the volume of sensor, easily be damaged in use procedure, and foil gauge is attached on center of effort's line of sensor elastomer, because paster or manufacturing tolerance, unbalance loading phenomenon is more or less there is in actual dynamometry, although comparatively accurate when vertical survey, when testee departs from test center's line, also error can be produced, deflect larger, error is also larger.In addition, these sensor two ends connect exterior part by screw, and use and install complexity, accessory is many, adds cost, and form is single, poor compatibility, and the scope of application is little.Pillar pull pressure sensor also has the shortcoming identical with S type pull pressure sensor.
Utility model content
The utility model will solve the problem of prior art, provides a kind of volume little, measures accurately, and without unbalance loading phenomenon, anti-deflection capacity is strong, compatible high, square shape pull pressure sensor applied widely.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of square shape pull pressure sensor, comprises sensor and foil gauge, and hollow out in square shape in the middle of described sensor, described foil gauge is located at both sides inside sensor.Such structure overcomes the unbalance loading of force acting on transducer; reach two panels force acting on transducer in theory balanced; and foil gauge is at sensor internal; play a very good protection; square shape cut-out places the annex that mainboard, battery etc. are generally arranged on sensor external in addition; this sensor is not only protected the electronic devices and components etc. of inside, and has effectively saved space, reduce volume.
Further, described sensor can be one-body molded, also can be made up of anter and rear panel two parts, and anter is identical with rear panel contour structures, and by the rivet of corner and and bottom gasket fix.Structure is simple, easy to process.
Further, described sensor upper and lower central authorities are respectively equipped with the link be connected with outside, and link can be pivot pin and nut structure or Suspension hook structure, and described pivot pin and nut structure connection external member, external member can be chain or shackle.Link and sensor one-body molded, save material, and connected mode has various ways optional, improves compatibility and the scope of application of sensor.
Further, described suspension hook is connected with sensor top or bottom by bearing, and suspension hook and bearing attachment are arranged with ball.When weighing, the related object that is weighed of suspension hook freely rotates, and the torsion reducing horizontal direction impacts sensor, improves the accuracy of measurement, extends the serviceable life of sensor.
Further, described bearing is coated with pad towards the middle side of sensor.Ensure that two panels sensor closely rivets together, as one piece of sensor, uniform force distributes.This design concept overcomes the unbalance loading of force acting on transducer, reaches two panels force acting on transducer in theory balanced.Also can prevent the foreign matters such as dust from entering bearing simultaneously, extend the serviceable life of bearing.
The beneficial effects of the utility model are: structure is simple, easy to process, measure accurately; overcome unbalance loading phenomenon, anti-deflection capacity is strong, and sensor construction can also as a part for shell; the foil gauge of good its inside of protection and other annexes; save space, reduce the volume of sensor, and sensor body is designed with the structure be connected with the external world; save material; reduce costs, few to field of employment restriction, improve compatibility and the scope of application of sensor.

Embodiment
Below by embodiment and accompanying drawing, the utility model is further described.
Composition graphs 1 and Fig. 2, a kind of square shape pull pressure sensor, comprises sensor 1 and foil gauge 2, and hollow out in square shape in the middle of sensor 1, foil gauge 2 is located at both sides inside sensor 1.Wherein, sensor 1 can be one-body molded, also can be made up of anter 11 and rear panel 12 two parts, and anter 11 is identical with rear panel 12 contour structures, and fixed by the rivet 3 of corner.Wherein, sensor 1 upper and lower central authorities are respectively equipped with the link be connected with outside, and link can be pivot pin 4 and nut 5 structure or suspension hook 8 structure.Wherein, pivot pin 4 and nut 5 anatomical connectivity external member 6, external member 6 can be chain or shackle.Wherein, suspension hook 8 is connected with sensor 1 top or bottom by bearing 7, and suspension hook 8 and bearing 7 coupling part are provided with ball 9, and bearing 7 is coated with pad 10 towards the middle side of sensor.
From the above, the utility model has numerous embodiments.
