Abstract
The utility model relates to a measure afterburning mechanism in small shearing strain device of material contains support frame, compression dynamometer, be provided with the flat just bracing piece of parallel placement in two genshui on the support frame, be provided with threaded connection's adjusting nut on the support frame, the setting of compression dynamometer is on two spinal branch vaulting poles, and one end is connected with the inner of adjusting nut, and the other end is provided with the distance rod, in operation, the other end of distance rod contacts with the one end of driving lever, the utility model discloses the shearing strain of directly inclining out is worth to improved measurement accuracy, and simple structure, convenient to use.
Description
Technical field
The utility model relates to Experiments of Machanics instrument field, refers in particular to a kind of boosting mechanism measured in the small shear strain device of material.
Background technology
Existing measurement material small shear strain device gives by boosting mechanism the shearing stress that one, vertical bar is very little, drive sample to produce to reverse, observe the angle of reflected light skew and combine the shear strain that the shearing stress value applied calculates material, but the shearing stress applied needs manual going to measure, not only measure inconvenience, and easily cause measuring error, thus reduce measuring accuracy, for this reason, we have developed a kind of boosting mechanism measured in the small shear strain device of material, directly can go out shear strain value in side, thus improve measuring accuracy.
Utility model content
The utility model object provides a kind of boosting mechanism measured in the small shear strain device of material to overcome the deficiencies in the prior art, directly can go out shear strain value in side, thus improve measuring accuracy.
For achieving the above object, the technical solution adopted in the utility model is: a kind of boosting mechanism measured in the small shear strain device of material, comprises bracing frame, compression dynamometer; Support frame as described above is provided with the support bar of two levels and parallel placement; Support frame as described above is provided with the setting nut be threaded; Described compression dynamometer is arranged on two support bars, and one end is connected with the inner of setting nut, and the other end is provided with distance rod; During work, the other end of described distance rod contacts with one end of driving lever.
Preferably, described setting nut is arranged between two support bars.
Preferably, the two ends of described support bar are fixed on bracing frame respectively by screw.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Boosting mechanism in the small shear strain device of measurement material described in the utility model directly can go out shear strain value in side, thus improves measuring accuracy, and structure is simple, easy to use; Be convenient to teacher by experiment and on classroom, explain abstract shear strain knowledge point, concrete image more, make classmate more acceptant, improve learning efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of the boosting mechanism in the small shear strain device of measurement material described in the utility model;
Wherein: 1, bracing frame; 2, driving lever; 3, screw; 4, support bar; 5, distance rod; 6, dynamometer is compressed; 7, setting nut.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1 is the boosting mechanism in the small shear strain device of measurement material described in the utility model, comprises bracing frame 1, compression dynamometer 6; Support frame as described above 1 is provided with the support bar 4 of two levels and parallel placement; The two ends of described support bar 4 are fixed on bracing frame 1 respectively by screw 3, are convenient to maintain and replace; Support frame as described above 1 is provided with between two support bars 4 setting nut 7 be threaded; Described compression dynamometer 6 is arranged on two support bars 4, and one end is connected with the inner of setting nut 7, and make compression dynamometer 6 uniform force, the other end is provided with distance rod 5; During work, the other end of described distance rod 5 contacts with one end of driving lever 2.
During use: first rotate setting nut 7 and compression dynamometer 6 reading is made zero; At rotation setting nut 7, promote distance rod 5 drive driving lever 2 to rotate by compression dynamometer 6, shear strain value can directly read on compression dynamometer 6.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Boosting mechanism in the small shear strain device of measurement material described in the utility model directly can go out shear strain value in side, thus improves measuring accuracy, and structure is simple, easy to use; Be convenient to teacher by experiment and on classroom, explain abstract shear strain knowledge point, concrete image more, make classmate more acceptant, improve learning efficiency.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
