Abstract
Description
Technical Field
[0001] This invention relates to the field of sensor installation and calibration auxiliary equipment technology, and specifically to an auxiliary device for temperature and humidity calibration of environmental testing equipment. Background Technology
[0002] Environmental testing equipment is a general term for all test chambers that simulate natural climatic environments. It is mainly used for reliability testing of industrial products, material performance inspection, and quality control. Temperature and humidity are the main test parameters of environmental testing equipment, and their accuracy and reliability directly affect the equipment performance and thus the reliability of product testing. Therefore, environmental testing equipment must be calibrated by metrology technicians according to JJF 1101-2019 "Calibration Specification for Temperature and Humidity Parameters of Environmental Testing Equipment". The chambers of environmental testing equipment are usually cuboid or cubic. JJF 1101-2019 requires that the temperature and humidity calibration of environmental testing equipment requires the placement of a certain number of standard temperature and humidity sensors in specified locations within the chamber. The sensor measurements are compared with the equipment's set values to obtain the equipment's indication error. According to JJF 1101-2019, the sensor placement requirements are as follows: Figure 1 As shown, the equipment volume is less than 2m³. 3 At that time, there were 9 temperature measurement points (numbers) and 3 humidity measurement points (letters). For example... Figure 2 As shown, the equipment volume is greater than 2m³. 3 At that time, there were 15 temperature measurement points (numbers) and 4 humidity measurement points (letters). The equipment volume was less than 0.5m³. 3 or greater than 50m 3 At the same time, the number of measurement points can be reduced or increased according to actual needs.
[0003] In actual testing work using environmental testing equipment, the placement of temperature and humidity sensors within the equipment enclosure presents the following difficulties:
[0004] 1. Difficult to install: Temperature and humidity sensors are usually wired or wireless probes, while calibration specifications require points to be suspended inside the enclosure, making direct installation impossible. Auxiliary materials or equipment such as wire, tape, or brackets are needed for placement, making the process cumbersome. For example... Figure 1 , Figure 2 As shown, the sensors are symmetrically and evenly distributed within the rectangular cavity, maintaining a certain distance from the cavity wall.
[0005] 2. Lack of universality: There are many models of environmental testing equipment, and the size and shape of the chamber space are different. Almost every piece of equipment needs to be designed and the calibration points need to be arranged separately.
[0006] 3. Difficulty in accurately locating calibration points: Environmental testing equipment requires symmetrical, uniform, and accurate temperature and humidity calibration points for effective metrological calibration. However, the difficulty in arranging sensor suspension points often leads to inaccurate calibration point locations, thus affecting the metrological calibration results. Summary of the Invention
[0007] The purpose of this invention is to provide an auxiliary device for temperature and humidity calibration of environmental testing equipment, in order to solve at least one of the above-mentioned problems existing in the prior art.
[0008] To achieve the above objectives, the present invention adopts the following technical solution:
[0009] An auxiliary device for temperature and humidity calibration of an environmental testing equipment includes a base, a connecting pipe, and a stainless steel flexible hose. The base is provided with a plurality of holes, including a central hole, an inner ring track hole, a middle ring track hole, and an outer ring track hole. The central holes are located in the middle of the base, the inner ring track holes are arranged along the inner ring track on the base, the middle ring track holes are arranged along the middle ring track on the base, and the outer ring track holes are arranged along the outer ring track on the base.
[0010] Multiple central holes include temperature sensor hole No. 5, temperature sensor hole No. 10, temperature sensor hole No. 15, and humidity sensor hole No. 0;
[0011] The multiple inner ring track holes include temperature sensor hole No. 1, temperature sensor hole No. 2, temperature sensor hole No. 3, temperature sensor hole No. 4 and humidity sensor hole No. A, wherein humidity sensor hole No. A is located close to temperature sensor hole No. 1.
[0012] The multiple central ring track holes include temperature sensor hole No. 11, temperature sensor hole No. 12, temperature sensor hole No. 13, temperature sensor hole No. 14, and humidity sensor hole No. C, wherein humidity sensor hole No. C is located immediately next to temperature sensor hole No. 13;
[0013] The multiple outer ring track holes include temperature sensor hole No. 6, temperature sensor hole No. 7, temperature sensor hole No. 8, temperature sensor hole No. 9 and humidity sensor hole No. B, wherein humidity sensor hole No. B is located close to temperature sensor hole No. 8.
[0014] The lower end of the connecting tube is provided with an external thread, which is threaded to the corresponding hole on the base. One end of the stainless steel flexible tube is sleeved on the connecting tube, and the other end of the stainless steel flexible tube is provided with a clamp. The clamp is used to hold and fix the sensing head of the temperature sensor or humidity sensor to be calibrated in the spatial position.
[0015] In this technical solution, the base provides stability for the entire auxiliary device. The base has several holes, including central holes, inner ring track holes, middle ring track holes, and outer ring track holes. Multiple central holes are located in the center of the base, multiple inner ring track holes follow the inner ring track on the base, multiple middle ring track holes follow the middle ring track on the base, and multiple outer ring track holes follow the outer ring track on the base. That is, the base has four sets of holes arranged according to different radius tracks. This arrangement of four sets of holes according to different radius tracks allows for accurate and orderly spatial placement of subsequent sensors. When the device is placed in the lower space, the outer ring track holes are used; when placed in the middle space, the middle ring track holes are used; and when placed in the upper space, the inner ring track holes are used. This layered arrangement of holes makes it easy to use different layers of holes according to different spaces, making it more convenient and efficient. In addition, the lower end of the connecting pipe is provided with an external thread, which is threaded to the corresponding hole on the base. The connecting pipe and the base are easy and quick to install, and the stainless steel flexible hose can be installed, fixed and disassembled very conveniently. The connecting pipe can be installed in the corresponding hole as needed. Specifically, depending on the upper, middle and lower layers of different equipment, the corresponding inner ring track hole, middle ring track hole and outer ring track hole can be selected. One end of the stainless steel flexible hose is fitted onto the connecting pipe, and the other end is equipped with a clamp. The clamp is used to hold and fix the sensing head of the temperature or humidity sensor to be calibrated in the spatial position. The stainless steel flexible hose is supportive and flexible, and its end can be quickly positioned in the appropriate space. The stainless steel flexible hose can be freely bent, rotated in all directions to adjust its direction, and extended and shaped. Its length can be adjusted by bending and stretching. At the same time, the stainless steel flexible hose has a certain mechanical strength to support its own weight and the weight of the sensor. After the sensor is fixed by clamping, the extension direction of the stainless steel flexible hose can be freely adjusted until the sensing head on the stainless steel flexible hose is positioned in the accurate spatial position. The stainless steel flexible hose can maintain the spatial position of the sensor. The overall spatial position calibration operation of the sensor is convenient, quick, and fast, with the speed of setting up one point measured in seconds. This device resembles an inverted octopus. When in use, each "tentacle" (stainless steel flexible hose) is directly extended to the accurate spatial position, which can easily, quickly, efficiently, and accurately set up temperature and humidity calibration points in the environmental test equipment chamber. The "tent" (stainless steel flexible hose) is adjustable in length and position, and can be accurately positioned in chambers of different sizes, improving the calibration efficiency and quality of environmental testing equipment.
[0016] In summary, the main function of this device is to arrange the spatial locations of sensors within the environmental testing equipment enclosure. This arrangement is primarily achieved using stainless steel flexible conduits. These conduits provide mechanical support while also offering good flexibility, enabling rapid, efficient, and accurate placement of the sensors, significantly improving the calibration efficiency of the environmental testing equipment. Common temperature and humidity sensor connection cables are typically flexible and prone to wear. Pre-assembly can be used, allowing the sensor cables to pass through the stainless steel conduits. The conduits also provide some protection for the temperature and humidity sensor wiring, reducing wear. This device has a simple structure, is very convenient to install and disassemble, is inexpensive, and possesses strong practicality.
[0017] Furthermore, the base is equipped with detachable metal legs along its edge, the total weight of which is 2kg to 3kg. These metal legs act as counterweights, providing stability to the entire auxiliary device.
[0018] Furthermore, the base is a hard plastic disc with a thickness of 1cm to 2cm and a diameter of 20cm to 30cm.
[0019] Furthermore, the connecting pipe is a stainless steel pipe.
[0020] Furthermore, the stainless steel tube is provided with a spring, and the stainless steel flexible tube is securely sleeved on the spring.
[0021] Furthermore, temperature sensor holes No. 1, No. 2, No. 3, No. 4, No. 5, No. 6, No. 7, No. 8, No. 9, No. 10, No. 11, No. 12, No. 13, No. 14, and No. 15 are all temperature sensor holes, with a diameter of 1 cm, and the outer diameter of the stainless steel tube connected to the temperature sensor hole is 1 cm; humidity sensor holes No. 0, No. 1, No. 1, No. 1, No. 1, and No. 15 are all humidity sensor holes, with a diameter of 1.5 cm, and the outer diameter of the stainless steel tube connected to the humidity sensor hole is 1.5 cm.
[0022] Furthermore, the stainless steel flexible hose includes stainless steel hose A and stainless steel flexible hose B. Stainless steel hose A has an inner diameter of 1 cm and is connected to a stainless steel hose with an outer diameter of 1 cm. Stainless steel hose B has an inner diameter of 1.5 cm and is connected to a stainless steel hose with an outer diameter of 1.5 cm.
[0023] Furthermore, the stainless steel pipe is 5cm long, and the stainless steel flexible tube is 50cm-100cm long.

[0041] The lower end of the connecting tube 21 is provided with an external thread 21.1, which is threaded to the corresponding hole on the base 20. One end of the stainless steel flexible tube 22 is sleeved on the connecting tube 21, and the other end of the stainless steel flexible tube 22 is provided with a clamp 23. The clamp 23 is used to clamp and fix the sensing head 24 of the temperature sensor or humidity sensor to be calibrated in the space.
[0042] In this technical solution, the base 20 provides stability for the entire auxiliary device. The base 20 has several holes, including central holes, inner ring track holes, middle ring track holes, and outer ring track holes. Multiple central holes are located in the center of the base 20. Multiple inner ring track holes are set along the inner ring track 20.1 on the base 20. Multiple middle ring track holes are set along the middle ring track 20.2 on the base 20. Multiple outer ring track holes are set along the outer ring track 20.3 on the base 20. That is, the base 20 has four sets of holes arranged according to different radius tracks. This arrangement of four sets of holes according to different radius tracks allows for accurate and orderly spatial placement of subsequent sensors. Specifically, when this device is placed in the lower space, the outer ring track hole (number six) is used. Temperature sensor holes 6, 7, 8, 9, and humidity sensor hole B (hole 18) are used. When the device is placed in the middle layer space, the middle ring track holes (temperature sensor holes 11, 12, 13, 14, and humidity sensor hole C (hole 19)) are used.

The stainless steel flexible tube 22 can be bent freely, rotated in all directions to adjust the direction, and extended and shaped. The length can be adjusted by bending and stretching. At the same time, the stainless steel flexible tube 22 has a certain mechanical strength to support its own weight and the weight of the sensor. After the sensor is clamped and fixed by the clamp 23, the extension direction of the stainless steel flexible tube 22 can be freely adjusted until the sensing head 24 on the stainless steel flexible tube 22 is positioned in the accurate spatial position. The stainless steel flexible tube 22 can maintain the spatial position of the sensor. The overall spatial position calibration operation of the sensor is convenient, quick, and fast, with the speed of one point measured in seconds.This device resembles an inverted octopus. In use, the "tentacles" (stainless steel flexible hoses 22) are extended to precise spatial positions, enabling simple, fast, efficient, and accurate placement of temperature and humidity calibration points within environmental testing equipment enclosures. The length and position of the "tentacles" (stainless steel flexible hoses 22) are adjustable, allowing for accurate placement in enclosures of different sizes, thus improving the calibration efficiency and quality of environmental testing equipment.
[0043] In summary, the main function of this device is to arrange the spatial locations of sensors within the environmental testing equipment enclosure. This arrangement is primarily achieved using the stainless steel flexible conduit 22. The stainless steel flexible conduit 22 provides mechanical support while also offering good flexibility, enabling rapid, efficient, and accurate spatial point placement, significantly improving the calibration efficiency of the environmental testing equipment. Common temperature and humidity sensor connection wires are often flexible and prone to wear. Pre-assembly can be used, with the sensor wires 25 passing through the stainless steel flexible conduit 22. The stainless steel flexible conduit 22 also provides some protection for the temperature and humidity sensor wiring, reducing wear. This device has a simple structure, is very convenient to install and disassemble, is inexpensive, and has strong practicality.

[0045] This embodiment is an optimization based on the above embodiment 1.
[0046] The base 20 has detachable metal legs 26 along its edge, with a total weight of 2kg to 3kg. The metal legs 26 serve as counterweights to provide stability for the entire auxiliary device. The base 20 is a hard plastic disc with a thickness of 1cm to 2cm and a diameter of 20cm to 30cm.
[0047] Example 3:
[0048] This embodiment is an optimization based on the above embodiment 1.
[0049] The connecting pipe 21 is a stainless steel pipe. A spring 27 is provided on the stainless steel pipe, and the stainless steel flexible hose 22 is securely fitted onto the spring 27. To accommodate the dimensions of the temperature sensor wire, temperature sensor holes 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, and 15 are all temperature sensor holes with a diameter of 1 cm. The outer diameter of the stainless steel tube connected to the temperature sensor hole is also 1 cm. To accommodate the dimensions of the humidity sensor wire, humidity sensor holes 16, 17, 18, and 19 are all humidity sensor holes with a diameter of 1.5 cm. The outer diameter of the stainless steel tube connected to the humidity sensor hole is also 1.5 cm.
[0050] Example 4:
[0051] This embodiment is an optimization based on the above embodiment 3.
[0052] Stainless steel flexible hose 22 includes stainless steel flexible hose A and stainless steel flexible hose B. Stainless steel flexible hose A has an inner diameter of 1cm and connects to a stainless steel hose with an outer diameter of 1cm. Stainless steel flexible hose B has an inner diameter of 1.5cm and connects to a stainless steel hose with an outer diameter of 1.5cm. The length of the stainless steel hose is 5cm, and the length of stainless steel flexible hose 22 is 50cm-100cm, which can be adjusted according to actual needs.
[0053] This device can be used in two ways: pre-assembled use and temporary use, as detailed below:
[0054] 1. Pre-assembly and usage steps:
[0055] The pre-assembled method is suitable for the calibration of commonly used and universal environmental testing equipment, such as drying ovens and baking ovens commonly used in laboratories. The size of their chambers is not much different, and they can be used interchangeably without disassembly after pre-assembly.
[0056] Before calibration, install the base 20, connecting tube 21 and stainless steel flexible tube 22, then insert the temperature sensor and humidity sensor into the tubes at the corresponding positions, and clamp the sensor head 24 with the clamp.
[0057] During calibration, place the pre-assembled device directly at the center of the bottom of the enclosure, and then adjust the stainless steel flexible hose 22 to ensure that each temperature sensor and humidity sensor is in the correct spatial position.
[0058] 2. Temporary usage steps:
[0059] This temporary method is applicable when the enclosure is particularly large, the stainless steel flexible hose 22 is too small to reach the space, and an appropriate length of stainless steel flexible hose 22 needs to be installed separately.
[0060] Before calibration, install the base 20, connecting pipe 21 and stainless steel flexible hose 22 of appropriate length.
[0061] During calibration, there is no need to insert tubes. The sensing heads 24 of the temperature and humidity sensors are clamped to the end of the stainless steel flexible tube 22 using the clamp 23. Then, the stainless steel flexible tube 22 is adjusted to make each temperature and humidity sensor reach the accurate spatial position.
[0062] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
