[0034] like Figure 1 to Figure 2 As shown, the embodiment of the utility model provides a strength test data acquisition instrument, comprising:

[0035] A housing 100, wherein a receiving space is formed in the housing 100;

[0036] A pressure monitoring circuit board 102 is disposed in the accommodation space and electrically connected to the pressure sensor 103;

[0037] The displacement monitoring circuit board 104 is disposed in the accommodation space and electrically connected to the displacement sensor 105;

[0038] The power supply 106 is disposed in the accommodation space and is electrically connected to the pressure monitoring circuit board 102 and the displacement monitoring circuit board 104 respectively.

[0039] The strength test data acquisition instrument provided by the embodiment of the utility model can receive and process signals from the pressure sensor 103 and the displacement sensor 105 in real time through the built-in pressure monitoring circuit board 102 and the displacement monitoring circuit board 104; it can understand the strength and displacement of the test object in real time, and provide accurate data support for further analysis and decision-making. Due to the use of a special pressure monitoring circuit board 102 and a displacement monitoring circuit board 104, the strength test data acquisition instrument can achieve high-precision measurement. This high-precision measurement helps users to understand the performance of the test object more accurately and improve the reliability and accuracy of the test. Through reasonable design, a housing space is formed inside the housing 100 of the data acquisition instrument, so that all components can be compactly integrated together. This not only improves the overall stability of the device, but also makes the device more portable, which is convenient for users to test in different scenarios. The setting of the power supply 106 ensures that the strength test data acquisition instrument has a stable power supply, thereby ensuring the stability and reliability of the device during long-term operation. In addition, the selection of circuit boards and sensors also takes into account their stability and durability, so that the entire device can work normally in harsh working environments.

[0040] Please continue to see Figure 1 and Figure 2 The strength test data acquisition instrument is mainly composed of a shell 100, a pressure monitoring circuit board 102, a displacement monitoring circuit board 104 and a power supply 106.

[0041] The housing 100 has a receiving space therein for receiving and protecting the internal circuit board and the power supply 106. The design of the housing 100 should take into consideration the portability, durability and use environment of the device, and may need to have certain waterproof, dustproof, shockproof and other functions.

[0042] The pressure monitoring circuit board 102 is disposed in the accommodation space of the housing 100 and is electrically connected to the pressure sensor 103. The pressure monitoring circuit board 102 is responsible for receiving signals from the pressure sensor 103 and converting these signals into data that can be processed and recorded by the device. The design of the pressure monitoring circuit board 102 should take into account its ability to accurately receive and process the signals of the pressure sensor 103, while also taking into account the stability and durability of the circuit board.

[0043] The displacement monitoring circuit board 104 is also disposed in the accommodation space of the housing 100 and is electrically connected to the displacement sensor 105. The function of the displacement monitoring circuit board 104 is to receive signals from the displacement sensor 105 and convert these signals into data that can be processed and recorded by the device. The design of the displacement monitoring circuit board 104 also needs to take into account its ability to accurately receive and process the signals of the displacement sensor 105, and also needs to take into account the stability and durability of the circuit board.

[0044] According to an embodiment of the present invention, a bracket 126 is disposed in the housing 100 , and the pressure monitoring circuit board 102 and the displacement monitoring circuit board 104 are respectively mounted on the bracket 126 .

[0045] The bracket 126 provides a stable support for the pressure monitoring circuit board 102 and the displacement monitoring circuit board 104, preventing the pressure monitoring circuit board 102 and the displacement monitoring circuit board 104 from being displaced or damaged due to vibration or external impact during the operation of the device. This helps to ensure the normal operation of the pressure monitoring circuit board 102 and the displacement monitoring circuit board 104 and the stability of data acquisition.

[0046] The design of the bracket 126 makes it easier to install and remove the pressure monitoring circuit board 102 and the displacement monitoring circuit board 104. The user can easily fix the pressure monitoring circuit board 102 and the displacement monitoring circuit board 104 in a suitable position through the bracket 126, or remove the pressure monitoring circuit board 102 and the displacement monitoring circuit board 104 from the bracket 126 for maintenance or replacement.

[0047] The power supply 106 is disposed in the accommodation space of the housing 100 and is electrically connected to the pressure monitoring circuit board 102 and the displacement monitoring circuit board 104, respectively. The main function of the power supply 106 is to provide power to the device to ensure the normal operation of the device. The power supply 106 may need to have sufficient power and stable voltage output to meet the needs of the device for long-term operation. At the same time, the design of the power supply 106 also needs to take into account the convenience of its replacement and charging.

[0048] According to an embodiment of the present utility model, a display screen 108 and a displacement pointer meter 110 are provided on the housing 100 . The display screen 108 is electrically connected to the pressure sensor 103 , and the displacement pointer meter 110 is electrically connected to the displacement sensor 105 .

[0049] According to the improvement of this embodiment, a display screen 108 and a displacement pointer meter 110 are provided on the housing 100 , and these two display components provide an intuitive data display method for the user.

[0050] The display screen 108 is electrically connected to the pressure sensor 103 and can display the pressure value of the test object in real time. This intuitive digital display method allows the user to quickly understand the current pressure status without additional interpretation or calculation. Through the combination of the display screen 108 and the displacement pointer meter 110, the user can simultaneously obtain digital and graphical data display, so as to more comprehensively understand the strength and displacement state of the test object. This diversified display method helps to improve the interactivity and user experience between the user and the device.

[0051] The displacement pointer meter 110 is electrically connected to the displacement sensor 105, and indicates the displacement of the test object by the movement of the pointer. The design of the pointer meter enables the user to intuitively observe the change of displacement, providing a quick reference for judging the deformation or movement of the object.

[0052] In addition, the test process can be more efficient because the user can directly read the data from the display screen 108 and the displacement pointer meter 110 without frequently checking or operating the equipment. This helps to reduce test time, reduce operating errors, and improve overall test efficiency.

[0053] According to an embodiment of the present invention, a first button 112 and a second button 114 are disposed on the housing 100 , and both the first button 112 and the second button 114 are electrically connected to the pressure monitoring circuit board 102 .

[0054] The first button 112 and the second button 114 provide the user with additional operation options, so that the user can more conveniently control the working state of the data acquisition instrument. For example, the user can start or stop data acquisition, adjust the acquisition frequency, or select different data acquisition modes, etc. by pressing the button.

[0055] The electrical connection with the pressure monitoring circuit board 102 means that the two buttons can directly control the data processing functions related to the pressure sensor 103. The user can trigger operations such as saving, deleting, and transmitting data, or adjust the display format and unit of the pressure data, etc. by pressing the buttons.

[0056] Compared to controlling devices through software interfaces or complex operating methods, the use of physical buttons is usually faster and more intuitive, which means that users can perform operations faster, reduce operation time, and thus improve work efficiency.

[0057] In addition, in some special usage scenarios, such as outdoor testing or harsh environments, using physical buttons may be more reliable and durable than touch screens or other operating methods.

[0058] According to an embodiment of the present invention, one of the first button 112 and the second button 114 is a pressure reset button, and the other of the first button 112 and the second button 114 is a peak value storage button.

[0059] In the embodiment of the present utility model, the first button 112 and the second button 114 are assigned specific functions: one of the buttons is used as a pressure reset button, and the other is used as a peak value storage button.

[0060] Taking the pressure reset button as an example, when the user needs to reset the pressure value before the test starts, they can reset the current pressure value to zero by pressing the pressure reset button. This helps ensure that each test starts from the same starting point, improving the accuracy and consistency of the test. In some cases, the sensor readings may drift due to long-term use of the equipment or environmental factors (such as temperature changes). By regularly resetting the zero, users can eliminate errors caused by these non-test factors and ensure the accuracy of the test data. The zeroing operation is usually simple and fast, and users can complete it in a short time, thereby speeding up the pace of testing and improving overall test efficiency.

[0061] Taking the peak save button as an example, during the strength test, peak data (i.e., maximum or minimum values) are often the most critical because they directly reflect the maximum bearing capacity or limit state of the test object. By pressing the peak save button, users can capture and save these important data for subsequent analysis and reference. In some cases, real-time data may be lost due to equipment failure, operating errors or other reasons. With the peak save function, users can ensure that at least part of the critical data is saved to reduce the risk of data loss. Since the peak data has been saved separately, users can focus more on other aspects of analysis during subsequent data processing without having to manually find and extract peak data, thereby simplifying the data processing process.

[0062] According to an embodiment of the present invention, a third button 116 and a fourth button 118 are disposed on the housing 100 , and both the third button 116 and the fourth button 118 are electrically connected to the displacement monitoring circuit board 104 .

[0063] In the embodiment of the utility model, a third button 116 and a fourth button 118 are added to the housing 100, and both buttons are electrically connected to the displacement monitoring circuit board 104. The third button 116 and the fourth button 118 are specifically used to control the acquisition and processing of displacement data, which means that the user can independently manage displacement-related operations without affecting the processing of pressure data. This separate control design makes the operation more precise and efficient. The electrical connection with the displacement monitoring circuit board 104 enables the two buttons to trigger a variety of data processing functions related to the displacement sensor 105. For example, the user can start or stop the recording of displacement data, select different sampling rates, or perform instant viewing and analysis of data by pressing a button. The introduction of physical buttons provides users with an intuitive and fast operation method. Compared with operating only through a software interface or a touch screen, the feedback of physical buttons is clearer, allowing users to more easily master the use of the device. In some test scenarios, such as requiring a quick response or in a high-noise environment, physical buttons may be more applicable than touch screens or other operation methods. The addition of the third button 116 and the fourth button 118 makes the device more adaptable to diverse test environments and user needs. By directly controlling the acquisition and processing of displacement data through buttons, users can control the test process more accurately and reduce human errors. At the same time, physical buttons are usually more stable and reliable than software operations, which helps to ensure the accuracy of test data.

[0064] According to an embodiment of the present invention, one of the third button 116 and the fourth button 118 is a displacement reset button, and the other of the third button 116 and the fourth button 118 is a balance button.

[0065] In the embodiment of the present invention, the third button 116 and the fourth button 118 are assigned specific functions: one of the buttons is used as a displacement reset button, and the other is used as a balance button.

[0066] Taking the displacement reset button as an example, when starting a new displacement test or needing to reset the displacement data, the user can reset the current displacement value to zero by pressing the displacement reset button. This helps ensure that each test starts from the same starting point, improving the accuracy and repeatability of the test. During continuous testing, the displacement data may have cumulative errors due to equipment factors or changes in test conditions. By periodically resetting the zero, the user can eliminate these errors and ensure the accuracy of the test data. The zeroing operation is usually simple and fast, and the user can complete it in a short time, thereby speeding up the test rhythm and improving the overall test efficiency.

[0067] Taking the balance button as an example, in some cases, the displacement sensor 105 may deviate due to improper installation, environmental changes or equipment aging. By pressing the balance button, the user can trigger the calibration process of the displacement sensor 105 to make its readings more accurate and reliable. The readings of the displacement sensor 105 may be interfered with by external factors (such as vibration, temperature changes, etc.). The design of the balance button can help users reduce these interferences and improve the stability of the test data. Under different test conditions, the performance of the displacement sensor 105 may vary. By pressing the balance button, the user can adjust the parameters of the sensor to better adapt it to the current test environment.

[0068] According to an embodiment of the present invention, a first potentiometer 120 and a second potentiometer 122 are disposed on the displacement monitoring circuit board 104 . The first potentiometer 120 is electrically connected to the displacement reset button, and the second potentiometer 122 is electrically connected to the balance button.

[0069] The first potentiometer 120 is electrically connected to the displacement reset button, allowing the user to set the threshold of displacement reset by adjusting the potentiometer. This means that the user can flexibly adjust the trigger condition of reset according to specific test requirements to better adapt to different test scenarios. Through the adjustment of the first potentiometer 120, the user can achieve more precise displacement reset control. For example, in some cases, the user may want the reset operation to be triggered only when the displacement value reaches a certain threshold, rather than simply resetting to zero. The first potentiometer 120 provides such flexibility. Setting the reset threshold by the first potentiometer 120 can also reduce the possibility of misoperation. For example, when the user accidentally presses the displacement reset button, the device will not be reset immediately due to the threshold limit, thereby avoiding unnecessary data loss.

[0070] The second potentiometer 122 is electrically connected to the balance button, allowing the user to calibrate the displacement sensor 105 by adjusting the potentiometer. This helps to eliminate deviations caused by long-term use, environmental factors or improper installation of the sensor, and improves the accuracy of the test data. By adjusting the second potentiometer 122, the user can adjust the sensitivity and response range of the displacement sensor 105 to better adapt it to different test conditions and environments. This helps to ensure that reliable test data can be obtained under different conditions. Traditional calibration of the displacement sensor 105 may require complex equipment and steps. Here, by simply adjusting the second potentiometer 122, the user can complete the calibration process, simplifying the operation process.

[0071] According to an embodiment of the present invention, a fifth button 124 is disposed on the housing 100 , and the fifth button 124 is electrically connected to the power supply 106 to control the opening and closing of the power supply 106 .

[0072] By providing the fifth button 124 on the housing 100, the user can easily turn on or off the power supply 106, thereby controlling the power supply of the entire device. This design makes power management more intuitive and convenient. In some cases, in order to avoid accidental startup of the device or prevent safety issues such as overheating of the device, the user can quickly cut off the power supply through the fifth button 124. This helps to reduce potential safety risks. When the device is not needed, the user can turn off the power supply through the fifth button 124 to save energy. This is particularly useful for scenarios where the device is not used for a long time or needs to be turned on and off frequently.

[0073] According to an embodiment of the present utility model, a charging port is provided on the housing 100 , and the charging port is electrically connected to the power supply 106 ;

[0074] and / or,

[0075] A handle 128 is provided on the housing 100 .

[0076] The setting of the charging port allows the user to charge the device by connecting to an external power source, ensuring that the device can be replenished in time when the power is low. This is especially important for devices that need to be used for a long time or moved frequently.

[0077] The provision of the handle 128 enables the user to conveniently lift and move the device, especially when the device is heavy or large in size, the handle 128 provides a comfortable gripping point and a convenient way of moving.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it.
