The patent No. is: " the precise leather shrinkage temperature tester " of ZL2003201097406, though changing original pointer-type into the LED numeral on display mode shows automatically, precision is improved, adopt the Single-chip Controlling temperature elevation system equally, but in the use of reality, still have defective and deficiency on some performances.Detect the method that locks its corresponding detected temperatures when the leather sample is subjected to thermal shrinkage deformation a certain amount of and shown by the contact angular displacement sensor and obtain shrinkage temperature as this, must under the situation of constant force 5g, detect by national regulation, so the error that is difficult to avoid current potential formula angular displacement sensor to cause owing to the reason of rotation axis stiction; Also have, when changing sample, whole testing jig all will lean on the manual operation of people to raise, and puts into heating medium (matchmaker's thing) after clipping sample again, and it is very inconvenient to operate; In addition, entire product is made up of two parts: Single-chip Controlling box and testing jig combine with the testing jig of calandria, thus make this whole instrument seem scattered and volume big, give to move, transportation and use are made troubles etc.
The patent No.: the patented technology of 2005201060167 " a kind of New-type leather shrinking temperature measuring instrument " makes the measurement of leather sample shrinkage temperature parameter than accurate, convenient in the past.But also there are the following problems in actual application: when adopting glycerine to measure the shrinkage temperature of the leather sample that (can reach 135 ℃) more than 100 ℃ as heating medium, this high temperature will cause that the Hall element in the non-contact displacement transducer that is in this glycerine and the performance parameter of magnetic cylinder change, thereby cause the accuracy of measurement of this instrument to descend.
The gordian technique that detects leather shrinking temperature is that requirement is used not only simple mode but also can accurately be gathered deformation (perhaps displacement) signal that the leather sample shrinks, and corresponding temperature signal then is easy to obtain by temperature sensor.The deformation signal that shrinks when the many disadvantages of foregoing leather shrinking temperature detector all is heated with collection leather sample with deficiency is relevant.So seek a kind of new method of shrinking deformation signal when gathering the leather sample and being heated, just become the key point that effectively addresses this problem.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of simple in structure, easy to use, stable performance is provided, and can once accurately measure the leather shrinking temperature measuring instrument of a plurality of leather samples.
For achieving the above object, the technical solution adopted in the utility model is: comprise well heater and be arranged on the interior strut support of well heater, be respectively arranged with testing stand and the sample hanging frame that is parallel to each other at the strut support upper/lower terminal, be characterized in, testing stand is provided with the magnetic cylinder more than a group, be provided with the constant force spring that is connected with last hook below the magnetic cylinder, sample hanging frame under the last hook be provided with on the corresponding lower draw-bar of hook, upper end at the magnetic cylinder is provided with Hall element, and also is provided with temperature sensor on strut support.
The permanent elastic force of constant force spring of the present utility model equals " 5 gram constant force " and adds that the weight sum of hook, magnetic cylinder, constant force spring and leather sample deducts its buoyancy in heating medium again; The height of temperature sensor is positioned at the centre of hook and lower draw-bar.
Because the utility model places normal temperature with Hall element and magnetic cylinder element, thereby cause before effectively having eliminated that the Hall element in the non-contact displacement transducer and the performance parameter of magnetic cylinder element are surpassing the reason that changes under 100 ℃ the glycerine environment, solved completely because high temperature causes the change key technical problem of the accuracy of measurement decline that causes this instrument of the performance parameter of Hall element and magnetic cylinder.
