Description

Technical Field

[0001] The utility model relates to the technical field of thermocouple and thermal resistance measurement, and specifically to a thermocouple and thermal resistance measurement structure. Background Art

[0002] A thermoresistance and thermocouple calibrator is a device used to calibrate and test thermoresistors and thermocouples. It is usually used to ensure the accuracy and reliability of temperature measurement. Thermoresistors and thermocouples are two commonly used temperature measurement tools that can measure temperature and output corresponding electrical signals. However, due to the influence of various factors, such as installation location, ambient temperature, wire resistance, etc., the measured electrical signal may have errors. Therefore, it is necessary to use a thermoresistance and thermocouple calibrator to calibrate and test the temperature sensor to ensure the accuracy and reliability of the measurement.

[0003] When the thermoresistance and thermocouple calibrator is installed and wired, if there is no limit on the wiring, the phenomenon of wiring detachment will occur, which will affect the performance and accuracy of the calibrator, resulting in inaccurate measurement results. If the position where the calibrator is installed is too loose or unstable, it may be affected by mechanical stress, resulting in deviation of the measurement results. Therefore, we propose a thermocouple and thermal resistance measurement structure and ensure its firm fixation. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a thermocouple and thermal resistance measurement structure to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A thermocouple and thermal resistance measurement structure, including a thermoresistance and thermocouple calibrator, the lower surface of the thermoresistance and thermocouple calibrator is fixedly connected with a concave frame, the lower surface of the concave frame is adhesively connected with a soft rubber sleeve, the inner cavity of the soft rubber sleeve is sleeved with a calibrator wiring, the rear side wall of the calibrator wiring is buckled with the front side wall of the concave frame, the top end of the calibrator wiring is connected with the lower surface of the thermoresistance and thermocouple calibrator, the front side wall of the concave frame is provided with a concave block, the rear side wall of the concave block is buckled with the front side wall of the calibrator wiring, and bolts are symmetrically sleeved on the front side wall of the concave block, and the concave block is fixedly connected with the concave frame through the bolts.

[0006] Preferably, a sleeve block is sleeved on the rear side wall of the calibrator wiring, rotating shafts are symmetrically installed on the inner wall of the sleeve block, a round roller is installed on the outer wall of the rotating shaft, the round roller is rotationally connected with the rotating shaft, and the side wall of the round roller is attached to the side wall of the calibrator wiring.

[0007] Preferably, the number of the rotating shafts is six, and they are symmetrically arranged horizontally in sequence.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: when using a thermal resistance thermocouple calibrator, a limit fixing structure is added to the bottom of the thermal resistance thermocouple calibrator. Through the cooperation of the concave block and the concave frame, the wiring of the calibrator can be fixed, and it is a symmetric snap connection, making the installation process of the calibrator wiring simple and convenient, easy to operate. When needed, the calibrator wiring can be easily removed, making the installation of the calibrator wiring stable, avoiding loosening and falling off, which may cause errors, so as to ensure the accuracy and reliability of measurement. A stable and reliable connection of the calibrator wiring can reduce the failure rate caused by loosening or falling off. Moreover, a soft rubber sleeve is provided at the end to better protect the calibrator wiring and prevent wear of the calibrator wiring when it is bent, thereby extending the service life of the calibrator wiring and ensuring the continuity and stability of measurement.
