Abstract
The utility model discloses a constant temperature test box used for measuring metal conductivity. The constant temperature test box comprises a box body used for containing a constant temperature medium, wherein a box cover is articulated on the box body; a probe hole for a conductivity meter to pass through and operating holes for both hands of a tester to pass through are arranged on the box cover; a grid plate used for supporting metal test pieces to be tested is arranged in the box body close to a box port; the box body is internally further provided with a constant temperature control meter; a top plate of the box cover is made of a transparent material; all the probe hole and the operating holes are provided with sealing covers; and the box body is made of a thermal insulating material. In the constant temperature test box bused for measuring the metal conductivity, a sealing structure and the constant temperature medium are adopted for controlling the temperature of the detection environment, so that compared with the prior art of controlling the temperature of large environment, the accuracy is better, the temperature is easier to control, and the testing result is more accurate. Moreover, the constant temperature test box is not affected by the large environment, so that the practicability is stronger.
Description
Technical field
The utility model relates to a kind of thermostat, particularly a kind of Homothermal Proof Box that is applied to the metal material detection range.
Background technology
Conductivity metal is very important metal material performance, and the method for at present main measurement conductivity metal is to adopt the metallic conductance appearance directly to measure.In the actual measurement process, influence measuring accuracy and comprise many-sided factor, wherein environment temperature is a principal element wherein.Generally speaking, temperature compensation is carried by the metallic conductance appearance and obtains a result after the temperature correction curve calculation gets.On the one hand, in the actual measurement, 20 ℃ of differences of temperature distance are big more, and its measured value and conductivity receive the temperature curve correction big more, and then the measurement data error is big more.So the laboratory measures ambient temperature is controlled at 20 ℃ ± 5 ℃.On the other hand, along with the carrying out of measuring, human body temperature is conducted to probe, and probe temperature rises and has influence on the accurate of measurement.The existing detection in the process of the test usually through the control ambient temperature, for example through air-conditioning control experiment indoor temperature, makes it as far as possible near 20 ℃, still, can't reach ideal effect all the time through control overall situation temperature, and it is bigger to detect error.
To above-mentioned deficiency, a kind of test unit need be provided, can keep test ambient temperature as far as possible near 20 ℃, guarantee the accuracy of experimental result.
The utility model content
In view of this, the purpose of the utility model provides a kind of Homothermal Proof Box that is used to measure conductivity metal, can control the unlimited approaching both fixed temperatures (20 ℃) of testing environment temperature in the chamber comparatively accurately, guarantees metal material tests result's accuracy.
The purpose of the utility model realizes through following technical scheme: a kind of Homothermal Proof Box that is used to measure conductivity metal; Comprise the casing that is used for the splendid attire thermostatic medium; The hinged case lid that is provided with on the said casing; Power supply is set on the case lid leads instrument probe probe hole that passes and the handle hole that supplies experimenter's both hands to pass, the interior Turbogrid plates that are provided for supporting metal specimen to be detected near case mouth position of said casing.
Further, in the said casing temperature controller is set also;
Further, the top board of said case lid is processed by transparent material;
Further, said probe hole and handle hole are provided with gland bonnet;
Further, said casing is processed by insulation material.
The beneficial effect of the utility model: the Homothermal Proof Box that is used to measure conductivity metal of the utility model; Owing to adopt closed structure and thermostatic medium to carry out the testing environment temperature controlling; Compare prior art control overall situation temperature; Degree of accuracy is better, and temperature controls more easily, and test findings is more accurate.And not influenced by overall situation, practicality is stronger.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:
Fig. 1 is the structural representation of the utility model.
Embodiment
Fig. 1 is the structural representation of the utility model.As shown in the figure: the Homothermal Proof Box that is used to measure conductivity metal of present embodiment; Comprise the casing 1 that is used for the splendid attire thermostatic medium; The hinged case lid 2 that is provided with on the said casing; Power supply is set on the case lid leads instrument probe probe hole 3 that passes and the handle hole 4 that supplies experimenter's both hands to pass, the interior Turbogrid plates 5 that are provided for supporting metal specimen to be detected near case mouth position of said casing.In the present embodiment, thermostatic medium adopts domestic water, draws materials easily; During detection, existing domestic water with 20 ℃ is contained in the casing 1, closes 2 a period of times of case lid; Make in the casing experimental situation temperature near after 20 ℃, test specimen to be detected is put on the Turbogrid plates 5, the conductivity meter probe is deep in the casing through probe hole 3; Experimenter's both hands are worn and are passed handle hole 4 behind the rubber gloves and carry out conductivity test; Through this chamber, can control the interior temperature range of casing in 20 ℃ ± 0.5 ℃, improve the accuracy of measuring greatly.
As further improvement, temperature controller is set also in the said casing to the foregoing description.Temperature controller is set more can controls temperature in the casing accurately, help accuracy of experimental results more.
As the further improvement to the foregoing description, the top board of said case lid 2 is processed by transparent material.Make things convenient for the directly interior situation of visual inspection casing of experimenter, operate more flexibly and fast, test efficiency improves greatly.
As the further improvement to the foregoing description, said probe hole 3 is provided with gland bonnet with handle hole 4.Before on-test, can make casing be in sealing state, help quick adjustment test the temperature inside the box.
As the further improvement to the foregoing description, said casing is processed by insulation material.Avoid chamber to conduct heat between inside and outside, help testing the temperature inside the box and continue constantly, guarantee the reliability of testing result.
Explanation is at last; Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Although the present invention is specified with reference to preferred embodiment; But those of ordinary skill in the art makes amendment to technical scheme of the present invention or is equal to replacement, and does not break away from the aim and the scope of technical scheme of the present invention, and it all should be encompassed in the middle of the claim scope of the present invention.
