Technical Field

[0001] This utility model relates to the field of constant temperature bath technology, specifically a constant temperature bath testing auxiliary device for temperature calibration. Background Technology

[0002] Precise temperature control and measurement are crucial in the use and calibration of thermostatic baths. Thermostatic baths are widely used in various experiments and industrial production processes requiring precise temperature environments, such as biopharmaceuticals, materials science, and chemical analysis. However, traditional thermostatic bath testing methods often rely on manual operation, which is not only inefficient but also prone to measurement errors due to human factors, affecting the calibration accuracy of the thermostatic bath.

[0003] For example, patent number 202422215107.X discloses an auxiliary device for testing a constant temperature bath for temperature calibration. However, this device requires manual operation by the user when testing the constant temperature bath, which, while enabling testing, is cumbersome in practice. Therefore, developing an automated, high-precision, and easy-to-operate auxiliary device for testing a constant temperature bath for temperature calibration is of significant practical importance.

[0020] Please see Figures 1-4In this embodiment of the present invention, a constant temperature bath testing auxiliary device for temperature calibration includes a fixed column 1, an extension plate 8 at one end of the fixed column 1, a movable groove 16 inside the extension plate 8, a stepper motor 17 movably connected to the inner wall of the movable groove 16, an adjusting electric push rod 10 fixedly connected to the bottom of the stepper motor 17, the bottom of the adjusting electric push rod 10 being movably connected through the bottom of the extension plate 8, the output end of the adjusting electric push rod 10 facing downwards, a temperature detection sensor 11 fixedly connected to the bottom of the output end of the adjusting electric push rod 10, and a distance sensor 15 fixedly connected to the outer wall of one side of the temperature detection sensor 11. A movable inner cavity 12 is formed inside the fixed column 1, and a through groove 6 is formed on the side wall of the fixed column 1 near the extension plate 8, the end of the through groove 6 near the movable inner cavity 12 being movably connected to the side wall of the movable inner cavity 12.

[0021] A lifting electric actuator 14 is fixedly connected to the bottom of the movable inner cavity 12. The output end of the lifting electric actuator 14 faces upward, and a movable block 13 is fixedly connected to the output end of the lifting electric actuator 14. The movable block 13 is movably connected inside the movable inner cavity 12. A connecting block 7 is fixedly connected to one end of the movable block 13 near the through groove 6. The connecting block 7 is movably connected through the through groove 6, and one end of the connecting block 7 passing through the through groove 6 is fixedly connected to the side wall of the extension plate 8.

[0022] Multiple indicator lights 9 are evenly fixedly connected to the top of the extension plate 8. A power connection wire 2 is fixedly connected through the bottom side wall of one end of the fixing post 1. A fixing plate 3 is fixedly connected to the bottom outer wall of the fixing post 1. Multiple fixing bolts 31 are threadedly connected through the top of the fixing plate 3. A buzzer 5 is fixedly connected to the top of the fixing post 1. A controller 4 is fixedly connected to the side wall of one end of the fixing post 1.

[0023] The working principle of this invention is as follows: the user sets the test parameters of the constant temperature bath, such as the test temperature and test time, through the controller 4. At the same time, the controller 4 calculates the optimal measurement position of the temperature detection sensor 11 based on the preset parameters.

[0024] Driven by the controller 4, the lifting electric actuator 14 begins to operate, moving the extension plate 8 up and down via the movable block 13 and connecting block 7 until the temperature detection sensor 11 reaches the preset height position. During this process, the distance sensor 15 monitors the distance between the sensor and the bottom of the constant temperature bath in real time to ensure positioning accuracy.

[0025] Under the control of the controller 4, the stepper motor 17 finely adjusts the angle of the electric actuator 10 to position the temperature sensor 11 at the optimal measurement point within the thermostatic bath. Subsequently, the temperature sensor 11 begins to measure the temperature within the thermostatic bath in real time and transmits the data to the controller 4 for processing and recording.

[0026] During testing, indicator light 9 displays the device's operating status in real time, such as normal testing or abnormal warnings. When an abnormal situation occurs, such as excessive temperature or sensor malfunction, buzzer 5 immediately sounds an alarm to remind the user to handle the situation promptly.

[0027] When the test time reaches the preset value or the user actively stops the test, controller 4 stops the control device and saves the test data for subsequent analysis. The user can view the test report or export the data to other devices for further processing through controller 4.
