DETAILED DESCRIPTION

[0025] In order to better understand the technical scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.

[0026] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification and claims of the present application and the above drawings are intended to cover non-exclusive inclusion, for example, a process, method, device, product or equipment comprising a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or equipment.

[0027] The following will be described in detail with reference to the accompanying drawings Figures 1-2 The present application will be further described in detail.

[0028] Reference Figures 1-2 The sensor brush writing clamp shown in the drawings comprises a base 1, a fixed seat 2, a sliding seat 3 and a limiting assembly provided on one side of the base 1, and an air channel 4 provided on the fixed seat 2; the sliding seat 3 is slidingly provided on the base 1, the sliding seat 3 is provided with a sealing head 5 for sealing one end of a sensor pressure detection tube, an opening of the air channel 4 close to the sliding seat 3 is an installation port, the installation port is provided opposite to the sealing head 5, and the sliding seat 3 is provided with a control assembly for controlling the sealing head 5 to move close to or away from the installation port; the limiting assembly is used for limiting the sliding of the sliding seat 3 on the base 1. In use, one end of the sensor pressure detection tube is placed in the installation port, then the sealing head 5 is controlled to move to the side of the fixed seat 2 by the control assembly until the sealing head 5 seals the other end of the sensor pressure detection tube, then the air channel 4 is connected to a gas supply device to supply pressure to the pressure sensor. When different specifications of pressure sensors need to be fixed, the limiting of the sliding seat 3 by the limiting assembly is released, the sliding seat 3 slides on the base 1 to make the sealing head 5 away from or close to the fixed seat 2, so that sensors of different specifications (lengths) of pressure detection tubes can be placed.

[0029] In order to better seal one end of the sensor pressure detection tube, a sealing groove is formed on the side of the sealing head 5 close to the fixed seat 2. In this way, when sealing, the sealing head 5 moves to place one end of the sensor pressure detection tube in the sealing groove. In order to improve the sealing effect, a sealing ring is arranged in the sealing groove to ensure that one end of the sensor pressure detection tube is sealed, thereby improving the accuracy of calibration.

[0030] Referring to Figures 1-2 As shown in the figure, the sliding seat 3 is provided with a sleeve ring 6, which is in the same straight line with the mounting port of the air duct 4. The end of the sealing head 5 away from the fixed seat 2 is provided with a sliding rod 7, which is slidingly arranged on the sleeve ring 6. In this way, the movement of the sealing head 5 is guided by the sleeve ring 6, ensuring that the sealing head 5 is sleeved on the sensor.

[0031] Referring to Figures 1-2 As shown in the figure, the control assembly includes a connecting piece 8, a limiting piece 9, and a wrench 10. The top surface of the sliding seat 3 is provided with a U-shaped frame 11, the sleeve ring 6 is arranged on one side of the top end of the U-shaped frame 11, one end of the limiting piece 9 is rotationally connected to the other side of the top end of the U-shaped frame 11, one end of the connecting piece 8 is rotationally connected to the suspended end of the limiting piece 9, and the other end is rotationally connected to the suspended end of the sliding rod 7. The wrench 10 is arranged on one end of the limiting piece 9 close to the connecting piece 8. In this way, the wrench 10 is held by hand, the connecting piece 8 is rotated, the connecting piece 8 and the limiting piece 9 are in the same straight line, the connecting piece 8 and the sliding rod 7 are in the same straight line, the maximum stroke of the sealing head 5 is reached, the sealing head 5 is in the state of sealing the sensor, and the connecting piece 8, the limiting piece 9, and the sliding rod 7 are in the same straight line, which can keep the sealing head 5 stable. When it is necessary to release the sealing of the sensor, the wrench 10 is held by hand, the angle between the connecting piece 8 and the limiting piece 9 is reduced, the sliding rod 7 moves towards the limiting piece 9, and the sealing head 5 moves away from the sensor, releasing the sealing and limiting of the sensor. In order to facilitate the user to operate, a non-slip sleeve is sleeved on the wrench 10 to avoid slipping and improve the comfort of use.

[0032] Referring to Figures 1-2 As shown in the figure, the limiting assembly includes two limiting plates 12 arranged in parallel on the base 1 and two bolts 14. The sliding seat 3 is arranged between the two limiting plates 12. The two limiting plates 12 are each provided with a through slot 13, the extension direction of the through slot 13 is consistent with the sliding direction of the sliding seat 3, and the threaded ends of the two bolts 14 respectively pass through the two through slots 13 and are threadedly connected to the two sides of the sliding seat 3. The head size of the bolt 14 is larger than the width of the through slot 13. In this way, when it is necessary to calibrate sensors of different specifications, the bolt 14 is rotated to move away from the limiting plate 12, then the sliding seat 3 is slid on the base 1 to the specified position, and then the bolt 14 is reversely rotated to fix the sliding seat 3. In order to accurately slide the sliding seat 3, the limiting plate 12 is provided with a scale 15 above the through slot 13. When calibrating sensors of different specifications, the position of the sliding seat 3 can be adjusted by referring to the scale 15, so that the sliding seat 3 can be moved to the required position more quickly.

[0033] Further optimization is as follows: Figure 2As shown, in order to avoid the reflux of gas into the airway 4, a pressure one-way valve 16 is arranged in the airway 4, and in order to facilitate the connection of the air supply device with the application, an air pipe joint 17 is arranged at the air inlet of the airway 4, facilitating the connection with the pipeline of the air supply device.

[0034] In summary, in use, one end of the sensor pressure detection pipe is placed in the mounting port, then the sealing head 5 is controlled to move to one side of the fixed seat 2 through the control assembly until the sealing head 5 seals the other end of the sensor pressure detection pipe, then the airway 4 is connected with the air supply device, so as to supply pressure to the pressure sensor, when it is needed to fix different specifications of pressure sensors, the restriction of the sliding seat 3 is released through the limiting assembly, the sliding seat 3 slides on the base 1, so that the sealing head 5 is away from or close to the fixed seat 2, so that the sensor of different specifications (length) of pressure detection pipes can be placed.

[0035] The above is only the preferred embodiment of the application, and the utility model is not limited to the above embodiments. It can be understood that other improvements and changes directly derived or thought of by those skilled in the art without departing from the spirit and concept of the utility model should be considered to be included in the protection scope of the utility model.
