Abstract

The utility model provides a length change rate measuring instrument, comprising a calibrated scale with measuring scales and a foldable scale with measuring scales connected with the calibrated scale, wherein the zero position of the foldable scale and the zero position of the calibrated scale are arranged together or located at a same straight line perpendicular to an axial direction. The length change rate measuring instrument has the beneficial effects of reducing recording amount, heightening experiment efficiency, and reducing error rate.

Description

The tensile strain rate measuring instrument

Technical field

The utility model relates to a kind of tensile strain rate measuring instrument, is applicable to the measurement of deriving and calculating each other between all lengths and the ratio.

Background technology

The following step of having of existing commercial measurement cloth washing shrinkage constitutes: 1, sample is tiled on the experiment table, on the warp of sample, latitude direction, carries out the preceding mark that contracts with marking pen,, in measurement singly, be designated as and wash preceding size with the tape measure length records; 2, sample is tiled on the experiment table after handling through each items such as washing, dry once more, with the mark lengths after the tape measure sample preparation, it is recorded on the measurement list, is designated as and washes the back size; 3, with counter calculate wash the back size deduct wash before the difference of size draw a number percent divided by size before washing again, be the tensile strain rate of sample, as be negative, be washing shrinkage, as be positive number, then be length growth rate.It is following not enough to adopt above step to exist: 1, the people is many for the hand-kept step, wash preceding, wash twice measured value in back all need the people for be recorded in measure single on, every many steps are artificial hand-written clerical mistake all might to occur; 2, the measured value of twice of front and back need be through the counter people for calculating the result; No matter be counter, artificially calculate or COMPUTER CALCULATION; All needing the people is typing; Therefore can calculate the result by recording gauge after need checking each result, take the experimental period more than measuring, still miscount can occur once in a while.

Summary of the invention

The purpose of the utility model provides and a kind ofly reduces the record amount, heightens conventional efficient, reduces the tensile strain rate measuring instrument of fault rate.

The technical scheme of the utility model is: the tensile strain rate measuring instrument; Comprise having the rule of measuring scale and being connected on the said rule and having the folding chi of measuring scale that the zero-bit of said folding chi is with the zero-bit setting of said rule or be positioned on the straight line of same direction perpendicular to axial direction.

Also comprise the vernier that is arranged on the said rule.

Said folding chi comprises the chi body, and said chi body is hinged in twos by the identical connecting link of some length and forms from beginning to end.

Said folding chi comprises the chi body; Cross-articulation becomes skeleton unit to said chi body at the middle part by two identical connecting links of length; Again the connecting link end of a plurality of skeleton units is hinged and forms; The connecting link end at said chi body two ends all is hinged with the chi head of V-type, and identical and length is that the half the connecting link end of connecting link length that constitutes skeleton unit is hinged and forms to said chi head by two length.

Advantage and the good effect that the utlity model has are:

1, the measured value before whole experiment only need be write down and washed just can draw the rate of change result of experiment, has reduced the almost mistake hidden danger of the overwhelming majority;

2, do not calculate link, saved the experimental period of the overwhelming majority in measurement in the experiment of shrinking, the calculation procedure, improved conventional efficient greatly;

3, owing to there is not calculation procedure, need only the correct necessity just do not checked of reading when measuring so, the counting loss rate is reduced to 0.

Embodiment

Embodiment one

As shown in Figure 1; The utility model comprises and has the rule 1 of measuring scale and be connected on the said rule 1 and have the folding chi 2 of measuring scale, and the zero-bit of said folding chi 2 is with the zero-bit setting of said rule 1 or be positioned on the straight line of same direction perpendicular to axial direction.

Also comprise the vernier 3 that is arranged on the said rule 1.

As shown in Figure 2, said folding chi 2 comprises chi body 4, and said chi body 4 is hinged in twos by the identical connecting link 5 of some length and forms from beginning to end.

The zero-bit of folding chi and rule fixedly coincides together; Folding chi extends and shrinks adjustment length arbitrarily in a groove parallel with rule; When the pointer of folding chi was adjusted to the original measurement size, the adjustment vernier moved it current mark; Pointer refers to the reading on folding chi on the observation vernier, writes down this rate of change numerical value.

Embodiment two

As shown in Figure 3; The utility model comprises and has the rule 1 of measuring scale and be connected on the said rule 1 and have the folding chi 2 of measuring scale, and the zero-bit of said folding chi 2 is with the zero-bit setting of said rule 1 or be positioned on the straight line of same direction perpendicular to axial direction.

Also comprise the vernier 3 that is arranged on the said rule 1.

As shown in Figure 4; Said folding chi 2 comprises chi body 6; Cross-articulation becomes skeleton unit 8 to said chi body 6 at the middle part by two identical connecting links 7 of length; Connecting link 7 ends of a plurality of skeleton units 8 being hinged forms again, and the connecting link end at said chi body 6 two ends all is hinged with the chi head 9 of V-type, and identical and length is that half the connecting link 10 ends of connecting link 7 length that constitute skeleton unit 8 are hinged and form to said chi head 9 by two length.

The course of work of this instance:

1, sample is tiled on the experiment table, on the warp of sample, latitude direction, carries out the preceding mark that contracts with marking pen, with measuring instrument measure length records measure single on, be designated as and wash preceding size.2, sample is washed, is dried etc. and sample is tiled on the experiment table after each item is handled again, with pointer on the measuring instrument transfer to wash before former mark, vernier caliper is pushed into present mark, record shrinks or the length growth rate result, is recorded in the measurement result place and gets final product.

Measure the tensile elasticity response rate of rectangle cloth together.1, the length before measuring samples stretches, record numerical value.2, sample is carried out the extension recovery of related experiment after, the length behind the measuring samples extension recovery, will fold the chi pointer transfer to stretch before scale, vernier is pushed into the sample length position, back that stretches, read tensile elasticity response rate numerical value.

More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
