[0052] A visual observation mirror 17 is provided on the first interference portion 13 and / or the second interference portion 14 , and an observation port 18 is provided on the first connecting pipe 15 and / or the second connecting pipe 16 .

[0053] The pipeline connector provided by the utility model includes a connector body 10, and the two ends of the connector body 10 are respectively provided with a first interference portion 13 and a second interference portion 14, the first interference portion 13 is connected to a first connecting tube 15 by interference fit, and the second interference portion 14 is connected to a second connecting tube 16 by interference fit. Firstly, the two ends of the connector body 10 are respectively connected to the first connecting tube 15 and the second connecting tube 16 by interference fit, and the sealing effect is initially guaranteed by the interference fit, ensuring that it has a good sealing effect and effectively reducing the occurrence of leakage problems.

[0054] Secondly, the two ends of the connector body 10 are respectively connected to the first connecting pipe 15 and the second connecting pipe 16 by interference fit, which can ensure that the installation process of the connector body 10 is simple, the operation is easier, the cost is very low, and the installation efficiency is high.

[0056] It can be understood that in order to ensure the sealing effect between the first interference portion 13 and the first connecting tube 15, and between the second interference portion 14 and the second connecting tube 16, the visual observation mirror 17 is arranged on the side of the first interference portion 13 away from the first connecting tube 15 or on the side of the second interference portion 14 away from the second connecting tube 16, so as to ensure that the first interference portion 13 and the first connecting tube 15, and between the second interference portion 14 and the second connecting tube 16 have sufficient interference fit connection surfaces.

[0057] In some embodiments of the present invention, the visual observation mirror 17 includes a mirror body 19 , which is a cylindrical structure. A plane lens 20 and a magnifying lens 21 are arranged inside the mirror body 19 .

[0058] In some of the above embodiments of the utility model, a plane lens 20 and a magnifying lens 21 are provided in the observation mirror. The magnifying lens 21 can improve the observation effect. The plane lens 20 and the magnifying lens 21 are provided at the same time, which can ensure the observation effect while ensuring that the visual observation mirror 17 has a good sealing effect.

[0059] It is understandable that the plane lens 20 and the magnifying lens 21 are both sealed and connected to the mirror body 19, thereby ensuring that the visual observation mirror 17 has a good sealing effect. In addition, the visual observation mirror 17 can also adopt existing products, which can be used for observation and can be assembled on the pipeline connector provided by the utility model.

[0060] In some embodiments of the present invention, a mounting opening is provided on the first interference portion 13 and / or the second interference section, and the visual observation mirror 17 is sealingly mounted on the mounting opening.

[0061] In some of the above-mentioned embodiments of the utility model, a mounting opening is provided on the first interference portion 13 and / or the second interference segment, and the visual observation mirror 17 is sealingly installed on the mounting opening, thereby realizing the sealed installation of the visual observation mirror 17; in addition, during assembly, the sealing effect can also be improved by increasing sealing watering.

[0062] In some embodiments of the present invention, the visual observation mirror 17 is integrally formed with the first interference portion 13 ; and / or the visual observation mirror 17 is integrally formed with the second interference portion 14 .

[0063] In some of the above embodiments of the present invention, by configuring the visual observation mirror 17 to be integrally formed with the first interference portion 13 or the second interference portion 14 , the sealing effect and positioning accuracy of the visual observation mirror 17 can be further ensured, thereby effectively guaranteeing the observation effect.

[0064] In some embodiments of the present invention, a plurality of annular protrusions 22 are disposed on the outer wall of the first interference portion 13 and / or the second interference portion 14 .

[0065] In some of the above embodiments of the present invention, by providing a plurality of annular protrusions 22 on the outer wall of the first interference portion 13 and / or the second interference portion 14 , the annular protrusions 22 can further ensure the sealing performance and connection reliability.

[0066] In some preferred embodiments of the present invention, the annular protrusion 22 is arranged obliquely, and the extension direction of the annular protrusion 22 toward the outside of the first interference portion 13 or the second interference portion 14 is opposite to the assembly direction of the first interference portion 13 or the second interference portion 14 .

[0067] In some of the above-mentioned preferred embodiments of the utility model, the inclination direction of the annular protrusion 22 is opposite to the assembly direction of the first interference portion 13 or the second interference portion 14, which can ensure that it can be quickly assembled and can play a role in loosening, effectively ensuring the assembly efficiency and sealing effect while ensuring that it has better connection reliability.

[0068] It should be noted that the inclination direction of the annular protrusion 22 is opposite to the assembly direction of the first interference portion 13 or the second interference portion 14, which means that when the first interference portion 13 is assembled with the first connecting tube 15 by interference fit, for example, the first connecting tube 15 is located on the left and the first interference portion 13 of the first pipe connector is located on the right, the first interference portion 13 needs to be moved to the left to achieve assembly. At this time, the annular protrusion 22 is inclined from the outer wall to the right side, so that when the first interference portion 13 is moved to the left for assembly, the annular protrusion 22 moves along with it, and when the first interference portion 13 is assembled and moves to the right, there is a greater friction between the annular protrusion 22 and the inner wall of the first connecting tube 15, which can increase the sealing effect and has an anti-detachment effect, thereby improving the connection reliability.

[0069] In some embodiments of the present invention, a hanging groove is provided on the inner wall of the first connecting tube 15 and / or the inner wall of the second connecting tube 16 , and the hanging groove is matched with the annular protrusion 22 .

[0070] In some of the above embodiments of the utility model, a hanging groove is provided on the inner wall of the first connecting tube 15 and / or the inner wall of the second connecting tube 16, and the hanging groove can cooperate with the annular protrusion 22 to form a more stable sealing structure, thereby improving its sealing effect and connection reliability.

[0071] In some specific embodiments of the present utility model, the connector body 10 includes a first connecting section 11 and a second connecting section 12, and a first end of the first connecting section 11 is connected to a second end of the second connecting section 12;

[0072] The first interference portion 13 is disposed at the second end of the first connecting segment 11 , and the second interference portion 14 is disposed at the first end of the second connecting segment 12 .

[0073] In some specific embodiments of the present utility model, in actual applications, there is inconsistency in the caliber sizes of the first connecting tube 15 and the second connecting tube 16. Therefore, the connecting piece body 10 includes a first connecting section 11 and a second connecting section 12.

The second end of the first connecting section 11 is connected to the first connecting tube 15 through a first interference portion 13, and the first end of the second connecting section 12 is connected to the second connecting tube 16 through a second interference portion 14. Therefore, it is suitable for the situation where there is inconsistency in the caliber sizes of the first connecting tube 15 and the second connecting tube 16, thereby improving its scope of application.

[0074] In some optional embodiments of the present invention, the outer diameter of the first connecting section 11 is the same as the inner diameter of the first connecting pipe 15 , and the outer diameter of the second connecting section 12 is the same as the inner diameter of the second connecting pipe 16 .
