Description

Technical Field

[0001] The present application relates to the technical field of calibration devices for constant temperature equipment such as water baths, ovens, box-type resistance furnaces, constant temperature and humidity chambers, and in particular to a calibration device for constant temperature equipment. Background Art

[0002] Constant temperature equipment includes but is not limited to ovens, water baths, gas baths, constant temperature and humidity, and resistance furnace constant temperature equipment. The principle is that when the equipment reaches a specified temperature value or relative humidity value, the temperature sensor or humidity sensor converts the measured working medium temperature or humidity into an analog electrical signal, which is processed by the control circuit and compared with the set temperature or set humidity and outputs a control signal to keep the working medium in the equipment's test space at a constant temperature and humidity. The national standards JJF201-2022 and JJF1101-2019 clearly specify the measurement and calibration methods, which determine the location and number of measurement points based on the size of the equipment's test space, and then measure and calculate the temperature or humidity deviation, uniformity, and fluctuation of the test space.

[0003] The current problem with the above test method is that during the detection process, it is necessary to arrange the test points as needed according to the size of the equipment's test space, and it is necessary to use a bracket to fix the probe to complete the measurement and calibration requirements. For constant temperature equipment, after determining the equipment's test space, the temperature sensor needs to be placed at the corresponding measurement point. However, the sizes of the test spaces of constant temperature equipment vary, and customer requirements are different, resulting in different temperature sensor placement locations. However, the existing measurement brackets cannot meet the measurement and calibration requirements of each type of constant temperature equipment. In addition, when testing oven-type, constant temperature and humidity-type, and water bath-type constant temperature equipment, since the equipment's test space needs to be closed after the point arrangement is completed, this operation will affect the position of the wired sensor, causing the sensor to shift at the designated measurement point, affecting the accuracy of the detection.

[0021] See also Figure 1 , Figure 1 It is a structural schematic diagram of a constant temperature equipment calibration device 100 provided by the present application, which specifically includes a bracket body 10, a telescopic component 20 and a first self-locking component 30. The entire constant temperature equipment calibration device 100 is a cubic structure, and the cubic structure here generally includes a rectangular parallelepiped structure or a cube structure. Among them, the bracket body 10 is composed of four tripods 101 arranged at four vertices in the same plane of the cubic structure, and at least one first hole 102 is opened on the tripod 101, and the first hole is used to penetrate the sensor line. The telescopic component 20 includes a plurality of relatively slidable coaxial hollow sleeves 201, and the coaxial hollow sleeves here can be 2 sections, 3 sections or more sections. The coaxial sleeves 201 of multiple sections are coaxially connected, and can be telescopically moved along the axial direction, and the length of the telescopic component 20 can be freely adjusted, thereby changing the length and width of the overall device. The two tripods 101 are connected by coaxial hollow sleeves 201, and the hollow sleeves 201 can facilitate the sensor line to be penetrated from the tube. The first self-locking component 30 is covered above the first hole 102 and is used to fix the sensor inserted into the first hole 102. Through the above embodiment, the telescopic function of the telescopic component 20 can be used to adjust the length and width of the entire device, quickly adapt to the detection spaces of various sizes of various thermostatic devices, and meet different space detection requirements. The sensor is inserted into the calibration device through the first hole 102 and the hollow sleeve 201, and the position of the sensor is fixed by the first self-locking component 30 to avoid the displacement of the sensor position caused by closing the thermostatic device. The device 100 has a reasonable structure, is easy to operate, can adapt to different test requirements, and effectively improves the accuracy of the measurement results.

[0022] Please refer again Figure 1In this embodiment, the first self-locking component 30 includes a spring (not shown in the figure) and a first cover plate 301, wherein the first cover plate 301 is covered above the first hole 102 by the spring. When the sensor needs to be fixed to the first hole 102 during the measurement process, the first cover plate 301 falls to clamp the sensor in the first hole 102. Of course, in other embodiments, they can also be connected by other means such as hinges. Through the above embodiment, the position of the sensor is fixed by the self-locking function of the first cover plate 301 and the spring, so as to avoid other operations affecting the position of the sensor, and effectively improve the accuracy of the measurement result.

[0023] In this implementation, please continue to refer to Figure 1 The tripod 101 includes three mutually perpendicular hollow support tubes, and the three mutually perpendicular hollow support tubes are welded and fixed to each other. The use of hollow support tubes can facilitate the wiring of the sensor to be arranged in the tube, and avoid the interlacing of the lines affecting the measurement effect of the sensor. Of course, in other embodiments, the tripod can also include multiple hollow support tubes, such as three mutually perpendicular hollow support tubes and a hollow support tube that is at a 45-degree angle to any two perpendicular hollow support tubes. This embodiment can increase the stability of the support body.

Of course, in other embodiments, more than two second holes 401 can be provided, which are specifically added according to the test requirements and the point arrangement of the sensor. Through the above embodiment, the length of the calibration equipment can be extended to adapt to the sensor calibration position, thereby meeting the test needs of measurement spaces of different sizes.

[0025] In this example, see Figure 1 , Figure 2 and Figure 3 The hollow support tube includes a first sleeve end 103, and the telescopic assembly 20 includes a second connection end 202 and a second sleeve end 203. The first hollow rod body 40 includes a third connection end 402 and a third sleeve end 403, the third connection end 402 is sleeved with the first sleeve end 103 of the hollow support tube, and the third sleeve end 403 is sleeved with the second connection end 202 of the telescopic assembly 20. In this embodiment, the outer diameter of the connection end matches the inner diameter of the sleeve end, which can facilitate the splicing of the hollow support tube, the first hollow rod body 40 and the telescopic assembly 20, thereby ensuring the stability of the structure.

[0026] Please review Figure 2In this embodiment, the first hollow rod 40 includes a second self-locking component 404, which is covered above the second hole 401 and is used to fix the sensor inserted into the second hole 401. The second self-locking component 404 fixes the position of the sensor inserted into the second hole 401, thereby avoiding the position deviation of the sensor caused by other factors, and effectively improving the accuracy of the measurement result.

[0027] Please continue reading Figure 2 The second self-locking component 404 includes a spring (not shown in the figure) and a second cover plate 405. The second cover plate 405 is connected to the first hollow rod body 40 through the spring, and the second cover plate 405 is arranged above the second hole 401.
