Description

Technical Field

[0001] The utility model relates to the field of horizontal surface temperature testing equipment, in particular to a supporting fixture used for measuring surface temperature with a handheld thermocouple. Background Art

[0002] In the field of temperature detection, the temperature is often measured by contacting the surface or interior of the object with a thermocouple temperature probe. It is suitable for various temperature measurement needs such as solid surface, liquid, gas, etc., and can be used in industrial production, R&D experiments, quality control and other occasions.

[0003] In the field of composite materials, gelation instruments are generally used to test the degree of reaction of resins. For gelation time testers, the production process has different temperature requirements for gelation time tests of different products, and the temperature accuracy of the surface hot plate is required to be high, so the measurement personnel need to frequently measure and adjust the temperature of the tester hot plate; because the area of ​​the instrument hot plate is very small, it is impossible to use a self-weight temperature measuring thermocouple for temperature measurement; the current measurement method is to measure the temperature by manually holding the temperature measuring thermocouple on the surface of the temperature plate of the instrument under test. This measurement method has some disadvantages, including the following points: 1. During the test, the measurement personnel cannot ensure the constant force between the thermocouple and the surface heat source by holding it, resulting in large fluctuations in the tester's indicated value, which is not convenient for reading accurate test results; 2. The temperature of the surface under test is generally a high-temperature surface, and the conventional temperature is greater than 150°C. In this case, the tester is at risk of being scalded by high temperature during the test, which poses a safety hazard; 3. This type of temperature measuring thermocouple temperature contact piece is easily damaged by multiple irregular manual pressing, causing loss of the test instrument and increasing costs.

[0004] Nowadays, thermocouples are used to measure important temperature parameters or pipe wall temperature during welding, and are generally fixed with a pressure plate or anti-slip bolts. The support fixture for measuring surface temperature with a handheld thermocouple described in the present application fixes the thermocouple through a lifting knob and a spring in a positioning mechanism to measure the surface temperature of an object with a planar structure. During the test, not only is the test stable and the reading convenient, but the manual operation is also simpler and safer. At the same time, by slotting the thermocouple compartment wall and installing a slide rod, the thermocouple will not rotate during the pressing process, reducing the wear of the thermocouple. In addition, the fixture can also be used to measure other types of objects, such as liquids, powders, pastes, etc., by replacing different types of temperature measuring thermocouples.

[0005] In order to overcome the defects in the prior art of measuring temperature by contacting the surface or interior of the object to be measured with a thermocouple temperature measuring probe, which cannot ensure balanced force, resulting in inaccurate test data; test personnel are easily burned by high temperature; and test instruments are easily damaged, the utility model provides a supporting fixture for measuring surface temperature with a handheld thermocouple, so that it can be stably placed on the surface to be measured and the temperature measuring thermocouple can fit tightly with the surface to be measured, thereby effectively and accurately measuring the surface temperature of the object and improving the safety of the test personnel.
