Butterfly tens(i)ometer on the market mainly includes sensing crushed element, transmitting portions and indicating section at present, described Sensing deformation part mainly includes contradicting the upper edge of a knife on object to be measured and contradicts the lower edge of a knife on object to be measured, described The lower edge of a knife can be rotated around itself midpoint, and the object deformation quantity to be measured of lower edge of a knife measurement, which is delivered on scale, to be shown.Its deficiency Part is：The upper edge of a knife, the transverse shifting of the lower edge of a knife are adjusted by the regulating device being fixed on mark post, described to adjust dress The stent including being fixed on a mark post is put, the stent is equipped with a guide post, compression spring is socketed with the guide post, compression spring Free end is contradicted on another mark post, which is difficult that the upper edge of a knife for making the lower edge of a knife and homonymy translates, therefore is operated tired Difficulty, and influence measurement result.

Utility model content

The purpose of this utility model is in view of the deficienciess of the prior art, the lower edge of a knife of the i.e. upper edge of a knife and homonymy is difficult to put down Move, influence measurement result, there is provided it is a kind of to translate the lower edge of a knife of the edge of a knife and homonymy, deformation is returned to zero and measured easy to scale The butterfly tens(i)ometer of amount.

A kind of improved butterfly tens(i)ometer, including base, offer the through hole passed through for object to be measured on the base, Base positioned at through hole both sides is equipped with sliding slot in the same horizontal line, slidably connects slide in each sliding slot, institute State slide and be equipped with and be used to contradict the upper edge of a knife on object to be measured, the lower knife for measuring object deformation quantity to be measured and show Show the scale of object deformation quantity to be measured, the center of gravity of the lower knife is hinged on slide, and one end of lower knife is contradicted in determinand On part, the other end is contradicted on the contact of scale.

During utility model works, object to be measured is passed through through hole by operating personnel first, and universal testing machine is by object to be measured Both ends clamp, then slide slide, the edge of a knife and one end of lower knife is contradicted on object to be measured, then to scale tune Zero, universal testing machine is started, object both ends to be measured is subject to the pulling force of quota, object to be measured deforms upon, the amount deformed upon Shown from scale, operating personnel calculate the elasticity modulus of object to be measured using formula according to the reading of scale.

Compared with prior art, the beneficial effects of the utility model are：Due to the presence of base, operating personnel can be adjusted Slide, makes to be connected to the upper edge of a knife on slide and lower knife integral translation, contradicts on object to be measured, consequently facilitating scale returns to zero Or read and treat measured value, therefore the time of the mobile upper edge of a knife and lower knife and the time to amesdial zeroing are shortened, simplify Operating process, substantially increases the detection efficiency of object elasticity modulus to be measured.

In order to ensure scale measures the accuracy of object deformation quantity to be measured, avoid base uneven to rotatably lower knife one A initial offset, so as to influence the measured value of scale, the base, which is equipped with, is used for measurement in the same horizontal line Level meter, multiple adjustable support legs for adjustment base levelness are screwed with the base.

In order to which the structure for measuring lower knife is accurately reacted on corresponding scale, the lower knife with scale contact Part is equipped with the protrusion easy to be touched with scale contact.

In order to more intuitively see the deformation quantity of determinand part, the slide is equipped with to be stretched for measuring object to be measured The mark post of amount, the free end of the mark post are connected with the edge of a knife.

In order to adjust vertically moving for the upper edge of a knife, the upper edge of a knife is handled rotation screw and is fixed on mark post.
