[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of an integrated metering device for multi-position pressure calibration, comprising a housing 1. A recording mechanism 3, a touch screen 4, and multiple mounting bases 2 are arranged on the upper side of the housing 1. The mounting bases 2 and the recording mechanism 3 are spaced at a preset distance. Inside the housing 1, a pressure generating device 5, a control circuit 10, and a power module 15 are arranged. The output end of the pressure generating device 5 is fixedly arranged on the lower side of the mounting base 2. The control circuit 10 is electrically connected to the recording mechanism 3, the touch screen 4, the pressure generating device 5, and the power module 15. The power module 15 is electrically connected to the pressure generating device 5.

[0026] In this embodiment, Figure 1 The front, back, left, and right are the directions. The power module 15 includes a battery pack and a battery management circuit to provide power to the device. The control circuit 10 includes a controller and a control circuit. The controller can be a microcontroller, microprocessor, or PLC programmable controller. All of the above are existing technologies.

[0027] Specifically, when using this device, several components to be tested are installed on the mounting base 2. The height of the recording mechanism 3 is adjusted according to the preset distance between the recording mechanism 3 and the mounting base 2, ensuring that the recording mechanism 3 is directly aligned with the component to be tested. Power is supplied to the device via the electrical connection of the power module 15 to the recording mechanism 3, the touch screen 4, the pressure generating device 5, and the control circuit 10. Corresponding commands are input via the touch screen 4. The electrical connection between the touch screen 4 and the control circuit 10, and the electrical connection between the control circuit 10 and the pressure generating device 5, activates the pressure generating device 5 and outputs a corresponding pressure value. The pressure is transmitted to the control circuit 10, and the pressure output by the pressure generating device 5 is transmitted to the mounting base 2 to perform pressure verification on the component under test on the mounting base 2. The pressure displayed by the component under test on the mounting base 2 is recorded by the recording mechanism 3 and transmitted to the control circuit 10. The control circuit 10 processes and analyzes the above data and displays the test results through the touch screen 4. This solves the problem that the existing technology has extremely low work efficiency when calibrating a large number of pressure instruments, and is also prone to calibration errors due to human data reading and recording, which affects the accuracy of the calibration results.

[0028] Reference Figure 4 and Figure 5 The pressure generating device 5 includes an electric pressure pump 14 and a main pressure supply pipe 12. The output end of the electric pressure pump 14 is fixedly installed at the input end of the main pressure supply pipe 12. Multiple pressure supply branch pipes 8 are fixedly installed at the output end of the main pressure supply pipe 12. An electric shut-off valve 9 and a pressure sensor 13 are installed inside the pressure supply branch pipe 8. The pressure sensor 13 is located above the electric shut-off valve 9. The upper end of the pressure supply branch pipe 8 is fixedly installed on the lower side of the mounting base 2. The power module 15 is electrically connected to the electric pressure pump 14. The control circuit 10 is electrically connected to the electric pressure pump 14, the electric shut-off valve 9, and the pressure sensor 13.

[0029] Specifically, the output end of the main pressure supply pipe 12 is connected to multiple pressure supply branch pipes 8 in parallel. When the pressure of the component under test is tested, the control circuit 10 controls the electric pressure pump 14 to start. Through the connection between the electric pressure pump 14 and the main pressure supply pipe 12, the pressure generated by the electric pressure pump 14 is transmitted to the main pressure supply pipe 12 and output to the multiple pressure supply branch pipes 8. The pressure sensor 13 measures the pressure in the pressure supply branch pipes 8 in real time and transmits the data to the control circuit 10 in real time. The control circuit 10 controls the adjustment of the electric shut-off valve 9, thereby controlling the opening and closing of the pressure supply branch pipes 8 and adjusting the pressure in the pressure supply branch pipes 8. Through the connection between the pressure supply branch pipes 8 and the mounting base 2, the mounting base 2, on which the component under test is installed, has the same pressure as that detected by the pressure sensor 13, thus realizing the function of rapid pressure verification of multiple units of the device.

[0030] Reference Figure 4 and Figure 5 The pressure generating device 5 also includes a manual pressure pump 16. A handle 6 is fixedly provided on one side of the manual pressure pump 16. The handle 6 is located outside the housing 1. The output end of the manual pressure pump 16 is fixedly provided on the input end of the pressure supply main pipe 12.

[0031] Specifically, a three-way pipe is fixedly installed at the input end of the main pressure supply pipe 12. The output ends of the electric pressure pump 14 and the manual pressure pump 16, as well as the input end of the main pressure supply pipe 12, are fixedly installed in the three directions of the three-way pipe. This device can also manually adjust the manual pressure pump 16 so that the pressure generated by the manual pressure pump 16 enters the main pressure supply pipe 12 and then enters multiple pressure supply branch pipes 8, realizing multiple pressure supply modes of the device, thereby realizing the function of manual and electric verification switching of the device.

[0032] Reference Figure 5 The pressure supply pipe 12 is also fixedly provided with a pressure relief pipe 7 at its output end, and the outer wall of the pressure relief pipe 7 passes through one side of the housing 1.

[0033] Specifically, the pressure relief pipe 7 and the pressure supply pipe 8 are connected in parallel. When the internal pressure of the device is too high, the pressure in the main pressure supply pipe 12 is discharged to the outside of the housing 1 through the pressure relief pipe 7, thereby helping to improve the safety of the device.

[0034] Reference Figure 5 The pressure relief pipe 7 is equipped with a pressure relief valve.

[0035] Specifically, when the pressure in the main pressure supply pipe 12 exceeds a certain level, the pressure relief valve in the pressure relief pipe 7 automatically opens to release pressure, thereby enabling the pressure relief pipe 7 to automatically release pressure.

[0036] Reference Figure 4 and Figure 5A partition 11 is fixedly connected to the inner wall of the housing 1. The partition 11 is located above the electric pressure pump 14. The pressure supply main pipe 12 and the control circuit 10 are both located on the upper side of the partition 11.

[0037] Specifically, the partition 11 divides the internal space of the housing 1 into upper and lower parts, which isolates the vibration and heat generated by the electric pressure pump 14, power module 15 and manual pressure pump 16 during operation, thereby helping to improve the stability of the pressure supply main pipe 12 and control circuit 10, and helping to extend the service life of the device.

[0038] Reference Figure 1 and Figure 5 The recording mechanism 3 includes a recording component 30 and a base 32. The base 32 and the mounting base 2 are spaced at a preset distance. The base 32 is fixedly connected to the upper side of the housing 1. The base 32 and the recording component 30 are slidably connected. A fastening knob 31 is threadedly connected to one side of the base 32. One end of the fastening knob 31 is attached to one side of the recording component 30. The recording component 30 is electrically connected to the control circuit 10 and the power module 15.

[0039] Specifically, when using this device, the component to be tested is installed on the mounting base 2. The base 32 and the mounting base 2 are aligned one-to-one and positioned appropriately by the preset distance between them. The recording component 30 is slid to the plane facing the component to be tested by the sliding connection between the base 32 and the recording component 30. The base 32 is screwed in by the threaded connection between the fastening knob 31 and the base 32, so that the base 32 abuts against the recording component 30, fixing the position of the recording component 30. The power supply module 15 supplies power to the recording component 30, and the electrical connection between the recording component 30 and the control circuit 10 allows the recording component 30 to transmit the recorded pressure value of the component to be tested to the control circuit 10 for processing and analysis, thereby avoiding errors caused by human recording of data and resulting in verification errors.

[0040] Reference Figure 1 , Figure 3 and Figure 5 The recording component 30 includes a slider 301. One end of the fastening knob 31 is attached to one side of the slider 301. The slider 301 is slidably connected inside the base 32, and the outer wall of the slider 301 passes through the upper side of the base 32. A lever 300 is fixedly connected to one side of the slider 301. A rectangular hole is opened on one side of the base 32, and the lever 300 is located in the rectangular hole opened in the base 32. A camera module 302 and a laser head 303 are provided on the upper end of the slider 301 near the mounting base 2. The camera module 302 is electrically connected to the control circuit 10 and the power module 15.

[0041] Specifically, when adjusting the recording component 30, the slider 301 is moved up and down by hand through the fixed connection between the lever 300 and the slider 301, the sliding connection between the slider 301 and the base 32, and the rectangular hole opened in the base 32. The laser head 303 illuminates the slider 301, causing it to fall at the 9 o'clock and 3 o'clock positions on the dial of the component under test. The slider 301 is then fixed by tightening the fastening knob 31. At this time, the camera module 302 is facing the center of the dial of the component under test. The power supply module 15 supplies power to the camera module 302, and the camera module 302 transmits the verification data to the control circuit 10 for processing and analysis, thereby completing the recording of the verification data and realizing the data recording function of the recording component 30.

[0042] Working principle: When using this device, several components to be tested are installed on the mounting base 2. The lever 300 is turned by hand to make the slider 301 move up and down. Through the illumination of the laser head 303, the camera module 302 is aligned with the center of the dial of the component to be tested. Then, the slider 301 is fixed by tightening the fastening knob 31, thereby completing the adjustment of the recording mechanism 3.

[0043] By inputting corresponding commands through the touch screen 4, the control circuit 10 controls the electric pressure pump 14 to start. The pressure generated by the electric pressure pump 14 is transmitted to the main pressure supply pipe 12, and then output to multiple pressure supply branch pipes 8. The pressure sensor 13 measures the pressure in the pressure supply branch pipes 8 in real time and transmits the signal to the control circuit 10 in real time. The control circuit 10 then controls the adjustment of the electric shut-off valve 9, thereby controlling the opening and closing of the pressure supply branch pipes 8 and adjusting the pressure. The pressure is then transmitted to the component under test on the mounting base 2, and the data of the component under test is transmitted to the control circuit 10 through the camera module 302. The control circuit 10 processes and analyzes the above data and displays the test results through the touch screen 4, thus completing the verification of one or more components under test. This solves the problem that the existing technology has extremely low work efficiency when verifying a large number of pressure instruments, and is also prone to verification errors due to human data reading and recording, which affects the accuracy of the verification results.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
