Description

Technical Field

[0001] This utility model relates to the field of atmospheric pressure measurement technology, and specifically to an atmospheric pressure measuring device. Background Technology

[0002] The main function of atmospheric pressure measuring devices is to measure and monitor changes in atmospheric pressure. In meteorological stations, weather forecasting, and climate research, atmospheric pressure measuring devices are used to monitor changes in atmospheric pressure. This data is crucial for predicting weather changes and analyzing climate trends. In industrial control systems, atmospheric pressure measuring devices are used to monitor and control air pressure changes in various equipment and processes to ensure the stability and quality of production processes. In the aerospace field, atmospheric pressure measuring devices are used to monitor changes in atmospheric pressure. This data is crucial for altitude, speed measurement, and navigation.

[0003] In the existing technology, atmospheric pressure is measured using an atmospheric pressure measuring device. Most atmospheric pressure measuring devices are usually suspended and fixed to the wall with expansion bolts or fixed to a support plate with bolts and nuts. However, atmospheric pressure measuring devices may malfunction during use and need to be disassembled for inspection and maintenance. Since the expansion bolts or bolts and nuts are fixed to the connection, disassembly tools are required to complete the operation, which is relatively troublesome.

[0004] Therefore, an atmospheric pressure measuring device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an atmospheric pressure measuring device in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] An atmospheric pressure measuring device includes an L-shaped support plate and a data control analyzer. A silicon resonant pressure sensor is mounted on the data control analyzer. A mounting hole is formed through the L-shaped support plate, and a fixing frame is provided on the surface of the L-shaped support plate. A positioning mechanism for mounting and positioning the data control analyzer is provided on the L-shaped support plate and is mounted on the data control analyzer. A clamping mechanism for holding and limiting the data control analyzer is provided on the fixing frame. A protective mechanism for preventing external dust from entering the silicon resonant pressure sensor is provided on the data control analyzer.

[0008] Furthermore, the positioning mechanism includes two positioning rods, which are symmetrically fixedly installed at the bottom of the data control analyzer. Two positioning grooves penetrate the surface of the L-shaped support plate, and the positioning rods are slidably installed on the inner wall of the positioning grooves.

[0009] Furthermore, the clamping mechanism includes a bidirectional lead screw, which is rotatably installed inside the fixed frame. Two clamping rods are threadedly installed on the outer wall of the bidirectional lead screw, and the clamping rods are slidably installed on the inner wall of the fixed frame. One end of the bidirectional lead screw extends outside the fixed frame, and a torsion handle is fixedly installed on the surface of the extended end of the bidirectional lead screw.

[0010] Furthermore, friction pads are fixedly provided on the surfaces of both clamping rods, and the friction pads are made of rubber.

[0011] Furthermore, a limiting plate is fixedly installed on the top of each of the two clamping rods, and the limiting plate is in contact with the data control analyzer.

[0012] Furthermore, the protective mechanism includes a threaded ring, which is installed on the top of the data control analyzer. One end of the silicon resonant pressure sensor is located inside the threaded ring, and a dustproof mesh is threaded onto the outer wall of the threaded ring.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model, through the setting of positioning mechanism, clamping mechanism, and protective mechanism, allows for the following: In use, the L-shaped support plate is fixed to the wall with expansion bolts or to the support plate with bolts and nuts. Then, with the cooperation of the positioning mechanism, the data control analyzer is positioned and installed on the L-shaped support plate. Subsequently, the clamping mechanism clamps and limits the data control analyzer, ensuring its stable placement on the L-shaped support plate. The protective mechanism prevents dust from entering the silicon resonant pressure sensor. Since the silicon resonant pressure sensor typically has a pressure conduction hole inside, dust entering the sensor may block this hole, causing the sensor to be unable to measure accurate data. If the data control analyzer or the silicon resonant pressure sensor malfunctions and requires maintenance, the clamping mechanism can be used to release the limit, allowing the data control analyzer to be directly removed from the L-shaped support plate. This facilitates the installation and disassembly of the data control analyzer and the silicon resonant pressure sensor, and protects the silicon resonant pressure sensor from dust. The operation is simple and highly practical. Attached Figure Description

[0025] like Figure 1-3As shown, an atmospheric pressure measuring device includes an L-shaped support plate 1 and a data control analyzer 5. A silicon resonant pressure sensor 6 is mounted on the data control analyzer 5. A mounting hole 2 passes through the L-shaped support plate 1. A fixing frame 3 is mounted on the surface of the L-shaped support plate 1. A positioning mechanism 4 for mounting and positioning the data control analyzer 5 is mounted on the L-shaped support plate 1 and is located on the data control analyzer 5. A clamping mechanism 7 for clamping and limiting the data control analyzer 5 is mounted on the fixing frame 3. External dust is blocked from the silicon resonant pressure sensor 6 on the data control analyzer 5. The protective mechanism 8, in this embodiment, is described as follows: the silicon resonant pressure sensor 6 is an A8000 series sensor with a maximum pressure range of 70 MPa and a high accuracy of 0.01% FS (including temperature compensation from -55 to 125 degrees Celsius). It is a high-precision, stable pressure sensor that utilizes the resonant characteristics of silicon material to convert changes in external pressure into changes in resonant frequency, thereby achieving accurate pressure measurement. This sensor features near-digital output and strong anti-interference capabilities, making it suitable for long-distance transmission and measurement in complex environments. The silicon resonant pressure sensor 6 can measure... The atmospheric pressure values ​​are transmitted in real time to the data control and analysis instrument 5. The data control and analysis instrument 5 can receive, analyze, and display these values ​​to help users understand the current atmospheric pressure situation. In use, the L-shaped support plate 1 is fixed to the wall with expansion bolts or fixed to the support plate with bolts and nuts. Then, with the cooperation of the positioning mechanism 4, the data control and analysis instrument 5 is positioned and installed on the L-shaped support plate 1. Subsequently, the clamping mechanism 7 clamps and limits the data control and analysis instrument 5, making it securely placed on the L-shaped support plate 1. The protective mechanism 8 can block dust. Entering the silicon resonant pressure sensor 6, it is possible to find that there is a pressure conduction hole inside the sensor. When dust enters the sensor, it may block this hole, causing the sensor to be unable to measure accurate data. If the data control analyzer 5 or the silicon resonant pressure sensor 6 malfunctions and needs to be repaired or maintained, the clamping mechanism 7 can be used to release the limit and directly remove the data control analyzer 5 from the L-shaped support plate 1. This facilitates the installation and removal of the data control analyzer 5 and the silicon resonant pressure sensor 6, and also protects the silicon resonant pressure sensor 6 from dust. The operation is simple and highly practical.

[0026] like Figure 2-3 As shown, the positioning mechanism 4 includes two positioning rods 402, which are symmetrically fixedly installed at the bottom of the data control analyzer 5. Two positioning grooves 401 penetrate the surface of the L-shaped support plate 1, and the positioning rods 402 are slidably installed on the inner wall of the positioning grooves 401. In this embodiment, by inserting the positioning rods 402 into the positioning grooves 401, the data control analyzer 5 is positioned on the L-shaped support plate 1.

[0027] like Figure 1-4 As shown, the clamping mechanism 7 includes a bidirectional lead screw 701, which is rotatably mounted inside the fixed frame 3. Two clamping rods 702 are threadedly mounted on the outer wall of the bidirectional lead screw 701, and the clamping rods 702 are slidably mounted on the inner wall of the fixed frame 3. One end of the bidirectional lead screw 701 extends outside the fixed frame 3, and a torsion handle 704 is fixedly mounted on the surface of the extended end of the bidirectional lead screw 701. In this embodiment, by rotating the torsion handle 704, the bidirectional lead screw 701 is driven to rotate, causing the two clamping rods 702 to move closer to or further away from each other, thereby adjusting the distance between the two clamping rods 702.

[0028] like Figure 3-4 As shown, friction pads are fixedly provided on the surfaces of both clamping rods 702, and the friction pads are made of rubber. In this embodiment, the setting of rubber friction pads enhances the frictional resistance in contact with the data control analyzer 5 and improves the stability of the fixation.

[0029] like Figure 3-4 As shown, limit plates 703 are fixedly installed on the top of both clamping rods 702, and the limit plates 703 are in contact with the data control analyzer 5. In this embodiment, the data control analyzer 5 is further limited by the setting of the two limit plates 703, thereby improving the stability of the suspension.

[0030] like Figure 1 , Figure 3 As shown, the protective mechanism 8 includes a threaded ring 801, which is installed on the top of the data control analyzer 5. One end of the silicon resonant pressure sensor 6 is located inside the threaded ring 801. A dustproof mesh tube 802 is threadedly installed on the outer wall of the threaded ring 801. In this embodiment, the dustproof mesh tube 802 can prevent external dust from entering the silicon resonant pressure sensor 6. Since the threaded connection between the threaded ring 801 and the dustproof mesh tube 802 is set, it is easy to install and disassemble.

[0031] In summary, the silicon resonant pressure sensor 6 is from the A8000 series, with a maximum pressure range of 70 MPa and a high accuracy of 0.01% FS (including temperature compensation from -55 to 125 degrees Celsius). It is a high-precision, stable pressure sensor that utilizes the resonant characteristics of silicon to convert changes in external pressure into changes in resonant frequency, thereby achieving accurate pressure measurement. This sensor features near-digital output and strong anti-interference capabilities, making it suitable for long-distance transmission and measurements in complex environments. Furthermore, the silicon resonant pressure sensor 6 can transmit the measured atmospheric pressure values ​​to the data control and analysis instrument 5 in real time. The data control analyzer 5 can receive, analyze, and display these values, thereby helping users understand the current atmospheric pressure conditions. In use, the L-shaped support plate 1 is fixed to the wall with expansion bolts or to the support plate with bolts and nuts. Then, with the cooperation of the positioning mechanism 4, the data control analyzer 5 is positioned and installed on the L-shaped support plate 1. Subsequently, the clamping mechanism 7 clamps and limits the data control analyzer 5, ensuring it is securely placed on the L-shaped support plate 1. The protective mechanism 8 prevents dust from entering the silicon resonant pressure sensor 6, as the silicon resonant pressure sensor 6 typically contains a... The air pressure conduction hole may become clogged when dust enters the sensor, preventing it from measuring accurate data. If the data control analyzer 5 or the silicon resonant pressure sensor 6 malfunctions and requires maintenance, the clamping mechanism 7 can be used to release the limit, allowing the data control analyzer 5 to be directly removed from the L-shaped support plate 1. This facilitates the installation and removal of the data control analyzer 5 and the silicon resonant pressure sensor 6, and also protects the silicon resonant pressure sensor 6 from dust. The operation is simple and highly practical. Inserting the positioning rod 402 into the positioning slot 401 will mount the data control analyzer 5 onto the L-shaped support plate 1. The upper positioning is achieved by rotating the torsion handle 704, which drives the bidirectional lead screw 701 to rotate, causing the two clamping rods 702 to move closer or further apart, thereby adjusting the distance between the two clamping rods 702. The rubber friction pad enhances the frictional resistance in contact with the data control analyzer 5, improving the stability of the fixation. The two limit plates 703 further limit the data control analyzer 5, improving the stability of the suspension. The dustproof mesh tube 802 prevents external dust from entering the silicon resonant pressure sensor 6. The threaded connection between the threaded ring 801 and the dustproof mesh tube 802 facilitates installation and disassembly.
