[0038] Specifically, when measuring the pressure of the sensor, the sensor is inserted between the mounting plate 1 and the limiting plate 2, after the sensor is installed, the fixture is placed in the corresponding pressure measuring box, the pressure measuring box is provided with a corresponding air pipe 4 for releasing high-pressure gas, the air pipe 4 in the pressure measuring box is communicated with the air hole 3 on the mounting plate 1, the high-pressure gas enters the trachea 4 from the air hole 3, and the trachea 4 will generate pressure on the sensor after the high-pressure gas is introduced.

[0039] Meanwhile, the bottom of the mounting plate 1 is provided with a corresponding communication device, and the communication device is provided with a corresponding communication line. When the clamp is placed in the pressure measuring box, the communication line will be connected with the host of the pressure measuring box. When the sensor senses the pressure transmitted by the air pipe 4, the communication line will transmit the pressure sensed by the sensor to the pressure measuring box, and then the host of the pressure measuring box will calculate the result of the pressure resistance test of the sensor.

[0040] In this way, the sensor is clamped and positioned by the mounting plate 1 and the limiting plate 2, so that the sensor can be effectively prevented from shaking during the pressure resistance test, thereby effectively ensuring the accuracy of the pressure resistance test result of the sensor.

[0041] Referring to Figure 1 and Figure 2 , the left and right ends of the mounting plate 1 are provided with a plurality of embedding grooves 12 for placing the communication line along the length direction of the mounting plate 1. The communication line is embedded in the embedding groove 12 to effectively ensure the stability of the communication line during the pressure measurement, thereby facilitating the accuracy of the pressure resistance test result.

[0042] Specifically, referring to Figure 1 and Figure 2 , the top of the mounting plate 1 is provided with a circular mounting hole 5, and the mounting hole 5 is in communication with the air pipe 4. The limiting plate 2 is provided with a limiting hole 6 penetrating through the limiting plate 2. The sensor is matched with the mounting hole 5 and the limiting hole 6. Specifically, when the sensor is installed, the bottom of the sensor is embedded in the mounting hole 5, and the bottom of the sensor passes through the mounting hole 5 and abuts above the air pipe 4. The top of the sensor vertically extends out of the limiting hole 6.

[0043] The limiting hole 6 and the mounting hole 5 limit the upper and lower ends of the sensor respectively, so that the clamping and positioning of the clamp on the sensor is more stable, thereby more effectively preventing the sensor from shaking during the pressure resistance test, thereby facilitating the accuracy of the pressure resistance test result of the sensor.

[0044] In this embodiment, the mounting hole 5 is provided with a plurality of mounting holes 5, and the mounting holes 5 are uniformly distributed along the length direction of the mounting plate 1, and the mounting holes 5 are arranged in two rows along the width direction of the mounting plate 1.

[0046] Referring to Figure 1 and Figure 2The fastener 8 is inserted between the mounting plate 1 and the limiting plate 2, penetrates the limiting plate 2, and is screwed to the mounting plate 1, so that the mounting plate 1 and the limiting plate 2 are tightly connected by the fastener 8, thereby effectively ensuring the stability of the connection between the mounting plate 1 and the limiting plate 2.

[0047] Specifically, referring to Figure 1 and Figure 2 , the mounting plate 1 and the limiting plate 2 are both provided with a circular connecting hole 7, and in the specific installation, the connecting holes 7 on the mounting plate 1 and the limiting plate 2 are aligned, and then the fastener 8 is inserted into the connecting holes 7 of the mounting plate 1 and the limiting plate 2.

[0048] In the embodiment, the connecting holes 7 are provided in multiple numbers, and the multiple connecting holes 7 are uniformly distributed along the length direction of the mounting plate 1 and the limiting plate 2. The multiple connecting holes 7 can simultaneously insert multiple fasteners 8 between the mounting plate 1 and the limiting plate 2, and the multiple fasteners 8 are used to connect the mounting plate 1 and the limiting plate 2, which is conducive to further ensuring the stability of the connection between the mounting plate 1 and the limiting plate 2.

[0049] In the embodiment, the fastener 8 is a fastening bolt, which is generally easy to find and replace.

[0050] Further, the air pipe 4 located in the mounting plate 1 can rotate in the mounting plate 1, and one side of the air pipe 4 is planar, and the other end is arc-shaped.

[0051] Specifically, referring to Figure 1 and Figure 2 , before the pressure test of the sensor, the side of the air pipe 4 in the planar shape faces upward, and the sensor is placed above the side of the air pipe 4 in the planar shape. When the pressure test of the sensor is completed, the air pipe 4 is rotated, and the side of the air pipe 4 in the arc shape gradually faces upward. While the air pipe 4 is rotating, the side of the air pipe 4 in the arc shape will lift the sensor inserted into the mounting hole 5 and the limiting hole 6 upward, and when the air pipe 4 is rotated, the side of the air pipe 4 in the arc shape will lift the sensor out of the limiting hole 6, thereby facilitating the workers to take the sensor.

[0052] Specifically, referring to Figure 1 and Figure 2 , the end of the air pipe 4 away from the air hole 3 is provided with a rotating shaft 9 in the horizontal direction, the rotating shaft 9 is provided with a rotating member 10, and the rotating shaft 9 and the rotating member 10 are both provided with a circular rotating hole 11.

The rotating tool can be a screwdriver or other parts.

[0054] The implementation principle of the air control pressure test clamp according to an embodiment of the application is as follows:

[0055] Specifically, when the sensor is subjected to pressure measurement, the sensor is inserted between the mounting plate 1 and the limiting plate 2. After the sensor is installed, the clamp is placed in the corresponding pressure measurement box. The pressure measurement box is provided with corresponding air pipes 4 for releasing high-pressure gas. The air pipes 4 in the pressure measurement box are connected to the air holes 3 on the mounting plate 1. The high-pressure gas enters the air pipes 4 from the air holes 3. The high-pressure gas in the air pipes 4 generates pressure on the sensor.

[0056] Meanwhile, the bottom of the mounting plate 1 is provided with a corresponding communication device. The communication device is provided with a corresponding communication line. When the clamp is placed in the pressure measurement box, the communication line is connected to the host computer of the pressure measurement box. When the sensor senses the pressure transmitted by the air pipes 4, the communication line transmits the pressure sensed by the sensor to the pressure measurement box. Then, the host computer of the pressure measurement box calculates the pressure test result of the sensor.

[0057] In this way, the sensor is clamped and positioned by the mounting plate 1 and the limiting plate 2. Therefore, the sensor can be effectively prevented from shaking during the pressure test. Thus, the accuracy of the pressure test result of the sensor can be effectively ensured.

[0058] The above are preferred embodiments of the application, and do not limit the protection scope of the application. Therefore, equivalent changes made on the basis of the structure, shape, and principle of the application should be covered within the protection scope of the application.
