Description

Technical Field

[0001] This utility model relates to the field of temperature and humidity sensor technology, specifically a combined air temperature and humidity sensor. Background Technology

[0002] In the field of environmental monitoring, temperature and humidity sensors are commonly used electronic devices for measuring ambient temperature and humidity, and their importance is self-evident. With the continuous development of technology, temperature and humidity sensors mostly use integrated temperature and humidity probes as temperature measuring elements, which can collect temperature and humidity signals and convert them into current or voltage signals that are linearly related to temperature and humidity. However, most existing temperature and humidity sensors are directly fixed in one place with bolts, and the probes of the temperature and humidity sensors are directly exposed to the air to detect the temperature and humidity in the air. However, due to long-term use, a lot of dust will adhere to the probe surface and it will not be protected, which will affect its detection effect, resulting in certain limitations in the use of the device, as well as affecting its service life and stability during use.

[0003] According to the patent application published on the Internet, a battery-powered temperature and humidity sensor with relay function (authorization announcement number: CN211783584U) is described as including a "signal rod, display screen" and other components to perform detection work.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] This battery-powered temperature and humidity sensor with relay function uses a signal rod and display screen to perform detection. During use, the first and second sliders are first fixedly installed on the upper surface of the temperature and humidity sensor body. The second slider is installed symmetrically with the center line of the temperature and humidity sensor body to fix the sensor at the position to be detected. However, the sensor's outer perimeter lacks protection, and the sensor is installed and removed by bolts, affecting the ease of use. The probe surface accumulates a lot of dust and lacks protection, which affects its detection performance. Therefore, this sensor needs to be improved. Utility Model Content

[0006] The purpose of this invention is to provide a combined air temperature and humidity sensor to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a combined air temperature and humidity sensor, including a mounting frame, a fixing mechanism on the front side of the mounting frame, and a mounting mechanism on the front side of the fixing mechanism;

[0008] The installation mechanism includes a fixed base located at the front of the fixing mechanism. A connecting frame is fixedly connected to the top of the fixed base. Protective plates are fixedly connected to the left and right sides of the connecting frame. A protective frame is inserted into the connecting frame and located at the front of the fixed base. A placement frame is fixedly connected to the front of the fixed base. A temperature and humidity sensor body is slidably connected inside the placement frame. A bidirectional threaded rod is rotatably connected inside the fixed base. An adjusting disc is fixedly connected to the left side of the bidirectional threaded rod. A limiting frame is threadedly connected to the outer periphery of the bidirectional threaded rod and located at the left side of the temperature and humidity sensor body. The limiting frame is slidably connected inside the fixed base. A movable frame is fixedly connected to the left side of the limiting frame and slidably connected inside the fixed base. An insert block is fixedly connected to the right side of the movable frame and is inserted into the connecting frame.

[0009] Preferably, the inner side of the protective frame is in contact with the front side of the fixed base, and the bottom of the protective frame and the bottom of the placement rack are respectively provided with wiring grooves, and the two wiring grooves correspond to each other, so as to facilitate the connection of the temperature and humidity sensor body to external equipment through the wiring grooves.

[0010] Preferably, the protective frame has a ventilation hole on the front side, and the inner side of the limiting frame is in contact with the left side of the temperature and humidity sensor body. The ventilation hole allows outside air to enter the protective frame, which facilitates the temperature and humidity sensor body to perform detection.

[0011] Preferably, the insert block extends through the interior of the protective frame, and the protective frame and the connecting frame are respectively provided with fixing slots, and the two fixing slots correspond to each other. The insert block is inserted into the fixing slot, which facilitates the stability of the protective frame under the action of the insert block, and also facilitates installation and disassembly.

[0012] Preferably, the connecting frame is provided in two sets, which are symmetrically distributed on the upper and lower sides of the fixed base, so as to further ensure the stability of the protective frame by passing through the two sets of connecting frames.

[0013] Preferably, the fixing mechanism includes a mounting base, which is fixedly connected to the front side of the mounting frame. A connecting plate is slidably connected inside the mounting base, and the connecting plate is fixedly connected to the rear side of the fixing base. A limiting shaft is inserted inside the mounting base, and a top plate is fixedly connected to the top of the limiting shaft. The top plate is disposed on the top of the mounting base, and a fixing pin is threaded inside the mounting base.

[0014] Preferably, the fixing pin passes through the limiting shaft and the connecting plate. The limiting shaft, the connecting plate and the mounting base are respectively provided with limiting grooves, and the three limiting grooves correspond to each other. The fixing pin is threaded into the limiting groove. The bottom of the top plate is in contact with the top of the mounting base, which facilitates the stability between the connecting plate limiting shaft and the mounting base under the action of the fixing pin, thereby facilitating the installation and disassembly of the mounting base.

[0015] Compared with the prior art, this utility model provides a combined air temperature and humidity sensor, which has the following advantages:

[0016] This combined air temperature and humidity sensor, through its designed mounting mechanism, allows for initial stabilization when used for air temperature and humidity detection. First, the sensor body is slidably connected to the mounting frame, achieving initial stability. Simultaneously, the external connection cable is connected to the sensor body via the wiring groove inside the protective frame and mounting frame. Then, the protective frame is slidably connected to the mounting frame. Rotating the adjusting disc causes the bidirectional threaded rod to move the limiting frame, bringing the inner side of the limiting frame into contact with the left side of the temperature and humidity sensor body. Two sets of limiting frames are available, thus securing both sides of the temperature and humidity sensor body. It is also easy to install and disassemble. During the movement of the limit frame, it will drive the moving frame and the plug to move, so that the plug can be inserted into the fixing groove inside the connecting frame and the protective frame. This ensures the stability of the protective frame and facilitates installation and disassembly. When the limit frame moves to the left and completely releases the limit on the temperature and humidity sensor body, the moving frame will not affect the movement of the limit frame. The protective frame provides physical protection for the temperature and humidity sensor body. The ventilation hole on the front side can effectively block the entry of foreign objects without affecting the accuracy of the sensor in detecting temperature and humidity, thus avoiding damage to the sensor due to interference from external impurities.

[0017] This combined air temperature and humidity sensor, through its fixed mechanism, allows the connecting plate to be slidably connected to the mounting base once the sensor body is installed under the action of the placement frame, fixed base, and limiting frame. Simultaneously, the limiting shaft is inserted into the mounting base, ensuring contact between the bottom of the top plate and the top of the mounting base. A fixing pin is threaded into the limiting grooves inside the limiting shaft, mounting base, and connecting plate, ensuring stability among the three components. This facilitates easy installation and disassembly of the fixed base, enabling rapid positioning and secure connection between the fixed base and the mounting frame. Once fixed, the mounting frame can be secured to the desired air temperature and humidity detection location using external fixing equipment, ensuring the stability of the mounting frame.

[0031] The mounting mechanism 3 includes a fixed base 31, which is located on the front side of the fixing mechanism 2. A connecting frame 32 is fixedly connected to the top of the fixed base 31. Protective plates 33 are fixedly connected to the left and right sides of the connecting frame 32. A protective frame 34 is inserted into the connecting frame 32. The protective frame 34 is located on the front side of the fixed base 31. A placement frame 37 is fixedly connected to the front side of the fixed base 31.

An adjusting plate 36 is fixedly connected to the left side of the bidirectional threaded rod 35. A limiting frame 39 is threadedly connected to the outer periphery of the bidirectional threaded rod 35. The limiting frame 39 is located on the left side of the temperature and humidity sensor body 38 and is slidably connected inside the fixed base 31. A movable frame 391 is fixedly connected to the left side of the limiting frame 39 and is slidably connected inside the fixed base 31. An insert block 392 is fixedly connected to the right side of the movable frame 391 and is inserted into the connecting frame 32.

[0032] The inner side of the protective frame 34 is in contact with the front side of the fixed base 31. The bottom of the protective frame 34 and the bottom of the placement rack 37 are respectively provided with wiring grooves, and the two wiring grooves correspond to each other, so as to facilitate the connection of the temperature and humidity sensor body 38 to external equipment through the wiring grooves.

[0033] Ventilation holes are provided on the front side of the protective frame 34.

The insert 392 passes through the inside of the protective frame 34. The protective frame 34 and the connecting bracket 32 ​​are respectively provided with fixing slots, and the two fixing slots correspond to each other. The insert 392 is inserted into the fixing slot, which facilitates the stability of the protective frame 34 under the action of the insert 392, and also facilitates installation and disassembly.

[0034] Two sets of connecting frames 32 are provided, and the two sets of connecting frames 32 are symmetrically distributed on the upper and lower sides of the fixed base 31, so as to facilitate the passage of the two sets of connecting frames 32 and further ensure the stability of the protective frame 34. Example 2

[0035] Please see Figure 1-7 Furthermore, based on Embodiment 1, the fixing mechanism 2 includes a mounting base 21, which is fixedly connected to the front side of the mounting frame 1. A connecting plate 22 is slidably connected inside the mounting base 21, and the connecting plate 22 is fixedly connected to the rear side of the fixing base 31. A limiting shaft 23 is inserted inside the mounting base 21, and a top plate 24 is fixedly connected to the top of the limiting shaft 23. The top plate 24 is located on the top of the mounting base 21, and a fixing pin 25 is threaded inside the mounting base 21.

[0036] The fixing pin 25 passes through the limiting shaft 23 and the connecting plate 22. Limiting grooves are respectively opened in the limiting shaft 23, the connecting plate 22 and the mounting base 21, and the three limiting grooves correspond to each other. The fixing pin 25 is threaded into the limiting groove. The bottom of the top plate 24 is in contact with the top of the mounting base 21, which facilitates the stability between the limiting shaft 23 and the mounting base 21 under the action of the fixing pin 25, thereby facilitating the installation and disassembly of the fixing base 31.

[0037] In actual operation, when this device is used, and when the temperature and humidity sensor body 38 is needed for air temperature and humidity detection, the temperature and humidity sensor body 38 is first slidably connected to the placement frame 37 in a preliminary stable state. At the same time, the external connection wire is connected to the temperature and humidity sensor body 38 through the protective frame 34 and the wiring groove inside the placement frame 37. At this time, the protective frame 34 can be slidably connected to the inside of the connecting frame 32. Rotate the adjusting plate 36 to make the bidirectional threaded rod 35 drive the limiting frame 39 to move, so that the inner side of the limiting frame 39 contacts the left side of the temperature and humidity sensor body 38. There are two sets of limiting frames 39, which can fix the left and right sides of the temperature and humidity sensor body 38 and facilitate installation and disassembly. During the movement of the limiting frame 39, the moving frame 391 and the insert block 392 will move, so that the insert block 392 is inserted into the fixing groove inside the connecting frame 32 and the protective frame 34, which can ensure the stability of the protective frame 34 and facilitate installation and disassembly.

[0038] When the temperature and humidity sensor body 38 is fixed, the connecting plate 22 can be slidably connected to the inside of the mounting base 21, and the limiting shaft 23 can be inserted into the inside of the mounting base 21, so that the bottom of the top plate 24 and the top of the mounting base 21 are in contact with each other. At the same time, the fixing pin 25 is threaded into the limiting groove inside the limiting shaft 23, the mounting base 21 and the connecting plate 22 to ensure the stability between the three, thereby facilitating the installation and disassembly of the fixing base 31. It can realize the quick positioning and stable connection between the fixing base 31 and the mounting frame 1. When the fixing is completed, the mounting frame 1 can be fixed in the position where air temperature and humidity detection is required by external fixing equipment to ensure the stability of the mounting frame 1.

[0039] When the limiting frame 39 moves to the left and completely releases the limiting of the temperature and humidity sensor body 38, the moving frame 391 will not affect the movement of the limiting frame 39. The protective frame 34 provides physical protection for the temperature and humidity sensor body 38. The ventilation hole on its front side can effectively block foreign objects from entering and prevent the sensor from being damaged by external impurities, while ensuring air circulation and not affecting the accuracy of the sensor in detecting temperature and humidity.

[0040] When the temperature and humidity sensor body 38 needs to be removed for maintenance and repair, simply remove the fixing pin 25, remove the connecting plate 22, and simultaneously move the bidirectional threaded rod 35 to move the limiting frame 39 and the moving frame 391. Remove the protective frame 34 to release the limiting of the temperature and humidity sensor body 38. The operation is convenient. In this case, the temperature and humidity sensor body 38 can be connected to an external display device for convenient observation of the detected values. The model of the temperature and humidity sensor body 38 is RS485 temperature and humidity sensor. The temperature and humidity sensor body 38 is existing technology, and those skilled in the art know only its working principle and usage method.
