Description

Technical Field

[0001] This utility model relates to the field of metrology technology, and in particular to a temperature and humidity probe fixing device for calibrating environmental testing equipment. Background Technology

[0002] The temperature and humidity probe fixing device for environmental testing equipment calibration is a specialized auxiliary tool designed specifically for the calibration process of environmental testing equipment. Its core function is to achieve accurate and stable fixing of the temperature and humidity probes. The device is made of high-quality materials that are resistant to high and low temperatures and corrosion. It can flexibly adjust the spatial position of the probe according to calibration requirements, ensuring that the probe sensing element is within the effective temperature and humidity range of the testing equipment, and avoiding probe displacement caused by airflow disturbances or equipment vibration. Its design not only solves the problems of inaccurate probe positioning and poor stability in traditional fixing methods, but also allows multiple probes to be fixed simultaneously for comparative calibration, significantly improving the accuracy and repeatability of calibration data. It is a key auxiliary device for ensuring the reliability of measurement value transfer in the metrological calibration of environmental testing equipment.

[0003] Existing temperature and humidity probe mounting devices use dedicated bushings for attachment. Different bushing shapes require different bushings for different probe shapes, but this one-to-one matching dictates that for scenarios using multiple non-standard probes, bushings of the corresponding specifications must be stocked in advance, increasing costs. Current technology uses magnetic attraction for quick probe mounting. A strong magnet is built into the clamping end of the device, paired with a probe adapter with a metal base. After mounting the probe on the adapter, it quickly attaches to the clamping assembly via magnetic attraction. The magnetic force can be controlled by adjusting the spacing between the magnets, making installation and removal convenient. However, the core sensing element of the temperature and humidity probe is sensitive to magnetic fields. The magnetic field generated by the strong magnet can interfere with the charge distribution or signal transmission within the sensing element, leading to measurement data deviations and reducing the probe's testing accuracy. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a fixing device for a temperature and humidity probe used in the calibration of environmental testing equipment. It aims to improve the problem that the core sensing element of the temperature and humidity probe in the prior art is sensitive to magnetic fields, and the magnetic field generated by the strong magnetic block will interfere with the charge distribution or signal transmission inside the sensing element, resulting in deviations in the measurement data and reducing the test accuracy of the probe.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a temperature and humidity probe fixing device for environmental testing equipment calibration, comprising a base, a fixing mechanism installed on the top outer side of the base, the fixing mechanism being used to clamp probes of different shapes, a rotating mechanism fixedly connected to the bottom outer wall of the fixing mechanism, the rotating mechanism being used to adjust the angle of the probe; the fixing mechanism includes a main shaft, the main shaft being installed on the top outer side of the base, a fixing frame fixedly connected to the rear outer wall of the main shaft, and limit blocks fixedly connected to the left and right sides of the front end of the outer wall of the main shaft, and a driving component installed on the outer wall of the limit blocks.

[0006] Preferably, the driving assembly includes a driving frame, with grippers rotatably connected to the left and right sides of the front end of the outer wall of the driving frame. The rear ends of adjacent sides of the outer walls of the multiple grippers are fixedly connected to the outer wall of the limiting block. A fixing half-ring is fixedly connected to the front ends of adjacent sides of the outer walls of the multiple grippers. A sliding plate is rotatably connected to the middle of adjacent ends of the outer walls of the multiple grippers. The outer wall of the sliding plate is slidably connected to the interior of the limiting block. A spring is fixedly connected to the rear side of the outer wall of the sliding plate. The rear side of the outer wall of the spring is fixedly connected to the front side of the outer wall of the fixing frame.

[0007] Preferably, the rotating mechanism includes a support frame, the top of the outer wall of the support frame is fixedly connected to the bottom of the outer wall of the fixed frame, the support frame is installed on the bottom of the outer wall of the fixed mechanism, a rotating disk is fixedly connected to the bottom of the outer wall of the support frame, a first mounting groove is formed in the middle of the bottom end of the rotating disk, and a power component is installed on the bottom of the outer wall of the rotating disk. The power component includes a motor, the motor is installed on the bottom of the rotating disk, a worm is fixedly connected to the output end of the motor, a worm wheel is installed on the right side of the outer wall of the worm, the right side of the outer wall of the worm meshes with the left side of the outer wall of the worm wheel, a rotating shaft is fixedly connected to the middle of the worm wheel, the top of the outer wall of the rotating shaft is fixedly connected to the inside of the first mounting groove, a bearing is fixedly connected to the bottom of the outer wall of the rotating shaft, a protective cover is installed on the outside of the motor, and the inner wall of the protective cover is fixedly connected to the outer wall of the motor.

[0008] Preferably, multiple load-bearing columns are fixedly connected at equal intervals to the bottom of the outer wall of the base, and anti-slip pads are fixedly connected to the bottom of the outer walls of each of the load-bearing columns. A mounting bracket is fixedly connected to the top of the outer wall of the base, and a second mounting groove is formed in the middle of the mounting bracket. A fastening knob is installed on the top outer side of the base, and the right end of the outer wall of the fastening knob is internally threaded to the left end of the mounting bracket. A support column with a rectangular design is slidably connected inside the second mounting groove.

[0009] This utility model has the following beneficial effects:

[0010] 1. In this utility model, pulling the drive frame causes the grippers on the left and right sides of the front end to rotate around the outer wall of the limiting block. When the grippers rotate, they cause the fixed half ring to open. At the same time, the grippers cause the sliding plate installed in the middle to slide inside the limiting block. The sliding plate moves and pulls the spring on its rear side to accumulate elastic potential energy. After the probe is placed between the fixed half rings, the drive frame is released. The spring returns to its original position and pulls the sliding plate to slide, thereby causing the grippers to rotate in the opposite direction, so that the fixed half ring clamps the probe. This achieves the fixation of probes of different shapes, avoids deviations in measurement data due to magnetic field interference, and improves the testing accuracy of the probe.

[0011] 2. In this utility model, the starting motor drives the worm gear to rotate. The worm gear meshes with the worm wheel on the right side, causing the worm wheel to drive the central rotating shaft to rotate. The bearing at the bottom of the rotating shaft is fixed to the top of the support column, which helps to stabilize the rotation of the rotating shaft. The rotating shaft is fixed in the first mounting groove at the bottom of the rotating disk. By rotating itself, it drives the rotating disk to rotate synchronously, thereby causing the rotating disk to drive the top support frame to rotate, and finally causing the top fixing mechanism to rotate, so as to adapt to the measurement requirements of different angles during the calibration of environmental testing equipment.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figure 2 , Figure 3 and Figure 4 One embodiment of this utility model is a temperature and humidity probe fixing device for calibrating environmental testing equipment, including a base 1, a fixing mechanism 2 installed on the top outer side of the base 1, the fixing mechanism 2 being used to clamp probes of different shapes, and a rotating mechanism 3 being fixedly connected to the bottom outer wall of the fixing mechanism 2, the rotating mechanism 3 being used to adjust the angle of the probe.

[0021] The fixing mechanism 2 includes a main shaft 201, which is installed on the top outer side of the base 1. A fixing frame 202 is fixedly connected to the rear side of the outer wall of the main shaft 201. Limiting blocks 203 are fixedly connected to the left and right sides of the front end of the outer wall of the main shaft 201. A drive assembly 204 is installed on the outer wall of the limiting block 203. The drive assembly 204 includes a drive frame 2041. Grippers 2042 are rotatably connected to the left and right sides of the front end of the outer wall of the drive frame 2041. The rear ends of adjacent sides of the outer walls of the grippers 2042 are fixedly connected to the outer wall of the limiting block 203. Fixed half rings 2043 are fixedly connected to the front ends of adjacent sides of the outer walls of the grippers 2042. Sliding plates 2044 are rotatably connected to the middle of adjacent ends of the outer walls of the grippers 2042. The outer wall of the sliding plate 2044 is slidably connected to the interior of the limiting block 203. A spring 2045 is fixedly connected to the rear side of the outer wall of the sliding plate 2044. The rear side of the outer wall of the spring 2045 is fixedly connected to the front side of the outer wall of the fixed frame 202.

[0022] Pulling the drive frame 2041 causes the grippers 2042 on the left and right sides of the front end to rotate around the outer wall of the limiting block 203. When the grippers 2042 rotate, they can cause the fixed half ring 2043 to open. At the same time, the grippers 2042 cause the sliding plate 2044 installed in the middle to slide inside the limiting block 203. The movement of the sliding plate 2044 can pull the spring 2045 on its rear side to continuously accumulate elastic potential energy. After the probe is placed between the fixed half rings 2043, the drive frame 2041 is released. The spring 2045 returns to its original position and pulls the sliding plate 2044 to slide, which in turn causes the grippers 2042 to rotate in the opposite direction, so that the fixed half ring 2043 clamps the probe. This achieves the fixation of probes of different shapes, avoids deviations in measurement data due to magnetic field interference, and improves the testing accuracy of the probe.

[0023] Reference Figure 3 and Figure 5 The rotating mechanism 3 includes a support frame 301. The top of the outer wall of the support frame 301 is fixedly connected to the bottom of the outer wall of the fixed frame 202. The support frame 301 is installed on the bottom of the outer wall of the fixed mechanism 2. A rotating disk 302 is fixedly connected to the bottom of the outer wall of the support frame 301. A first mounting groove 303 is provided in the middle of the bottom end of the rotating disk 302. A power component 304 is installed on the bottom of the outer wall of the rotating disk 302.

[0024] The power assembly 304 includes a motor 3041, model 130ST-M15015. Its internal driver receives external commands (such as position pulses and speed signals) and simultaneously acquires the actual rotor state via an encoder. If there is a deviation between the actual state and the command, the driver adjusts the stator current, changing the rotational magnetic field speed or direction until the deviation is eliminated, achieving high-precision control. The motor 3041 is mounted on the bottom of the rotating disk 302, and a worm gear 30 is fixedly connected to the output end of the motor 3041. 42. A worm wheel 3043 is installed on the right side of the outer wall of the worm 3042. The right side of the outer wall of the worm 3042 is meshed with the left side of the outer wall of the worm wheel 3043. A rotating shaft 3044 is fixedly connected to the middle of the worm wheel 3043. The top of the outer wall of the rotating shaft 3044 is fixedly connected to the inside of the first mounting groove 303. A bearing 3045 is fixedly connected to the bottom of the outer wall of the rotating shaft 3044. A protective cover 3046 is installed on the outside of the motor 3041. The inner wall of the protective cover 3046 is fixedly connected to the outer wall of the motor 3041.

[0025] The motor 3041 is started, and its output end can drive the worm gear 3042 to rotate. Through the meshing of the worm gear 3042 and the right worm wheel 3043, the worm wheel 3043 drives the central rotating shaft 3044 to rotate. The bearing 3045 at the bottom of the rotating shaft 3044 is fixed to the top of the support column 9, which can help the rotating shaft 3044 to rotate stably. The rotating shaft 3044 is fixed in the first mounting groove 303 at the bottom of the rotating disk 302. By rotating itself, it drives the rotating disk 302 to rotate synchronously, thereby causing the rotating disk 302 to drive the top support frame 301 to rotate, and finally causing the top fixing mechanism 2 to rotate, so as to adapt to the measurement requirements of different angles during the calibration of environmental test equipment.

[0026] Reference Figure 1 , Figure 2 and Figure 3 Multiple load-bearing columns 4 are fixedly connected at equal intervals on the bottom of the outer wall of the base 1. Anti-slip pads 5 are fixedly connected to the bottom of the outer wall of each load-bearing column 4. A mounting bracket 6 is fixedly connected to the top of the outer wall of the base 1. A second mounting groove 8 is opened in the middle of the mounting bracket 6. A fastening knob 7 is installed on the top of the outer side of the base 1. The right end of the outer wall of the fastening knob 7 is internally threaded to the left end of the mounting bracket 6. A support column 9 is slidably connected inside the second mounting groove 8. The support column 9 adopts a rectangular design.

[0027] The base 1 has multiple load-bearing columns 4 evenly spaced at the bottom, each with anti-slip pads 5 to prevent it from sliding during use and improve the overall stability of the structure. The base 1 has a mounting bracket 6 at the top, with a second mounting groove 8 in the middle. The second mounting groove 8 provides space for the installation and movement of the support column 9. The fastening knob 7 can be rotated to adjust the fixing state of the support column 9 and prevent it from moving within the second mounting groove 8. The support column 9 adopts a rectangular design to enhance its structural stability and prevent it from shifting during support.

[0028] Working principle: Pulling the drive frame 2041 causes the grippers 2042 on the left and right sides of the front end to rotate around the outer wall of the limiting block 203. When the grippers 2042 rotate, they can cause the fixed half ring 2043 to open. At the same time, the grippers 2042 cause the sliding plate 2044 installed in the middle to slide inside the limiting block 203. The movement of the sliding plate 2044 can pull the spring 2045 on its rear side to continuously accumulate elastic potential energy. After the probe is placed between the fixed half rings 2043, the drive frame 2041 is released. The spring 2045 returns to its original position and pulls the sliding plate 2044 to slide, which in turn causes the grippers 2042 to rotate in the opposite direction, so that the fixed half ring 2043 clamps the probe. This achieves the fixation of probes of different shapes, avoids deviations in measurement data caused by magnetic field interference, and improves the testing accuracy of the probe.

[0029] The motor 3041 is started, and its output end can drive the worm gear 3042 to rotate. Through the meshing of the worm gear 3042 and the right worm wheel 3043, the worm wheel 3043 drives the central rotating shaft 3044 to rotate. The bearing 3045 at the bottom of the rotating shaft 3044 is fixed to the top of the support column 9, which can help the rotating shaft 3044 to rotate stably. The rotating shaft 3044 is fixed in the first mounting groove 303 at the bottom of the rotating disk 302. By rotating itself, it drives the rotating disk 302 to rotate synchronously, thereby causing the rotating disk 302 to drive the top support frame 301 to rotate, and finally causing the top fixing mechanism 2 to rotate, so as to adapt to the measurement requirements of different angles during the calibration of environmental test equipment.
