[0052] With the above structure, when the connector 1 is connected, the head 13 abuts against other parts, and the first tooth 122 abuts against and is pressed against the material of other parts to form an interlocking structure.

[0053] According to the above-described fitting structure, the first tooth 122 enables the connector 1 to have anti-rotation capability after connection, thereby further improving the reliability of the connector 1 connection.

[0054] In the above structure, the connector 1 is provided with a connecting cavity 11. It can be understood that the connecting cavity 11 is opened from the head 13 and extends toward the riveting part 14. In this embodiment, preferably, the connecting cavity 11 is a through hole or a blind hole.

[0055] Based on the above structure, those skilled in the art can configure the connecting cavity 11 as a through hole. In this embodiment, the riveting part 14 can be riveted to the external part, thereby completing the connection of the connector 1. In another embodiment, the connecting cavity 11 is configured as a blind hole, and the riveting part 14 can be riveted to the external part, thereby also completing the connection of the connector 1.

[0056] In the above embodiment, the riveting portion 14 is used for connection. Preferably, a second tooth 141 is provided at the connection between the riveting portion 14 and the connecting portion. The second tooth 141 is continuously distributed and closed along the circumferential direction of the outer wall of the riveting portion 14. The second tooth 141 is provided on the riveting portion 14 so that it can be fitted into the material of the external part, thereby improving the ability of the riveting portion 14 to prevent rotation after connection.

[0057] In summary, those skilled in the art can significantly improve the anti-rotation capability of the connector 1 after it is connected by setting the first tooth 122 and the second tooth 141.

[0058] Furthermore, in this embodiment, preferably, the riveting portion 14 is recessed at the connection point with the second tooth portion 141 in the direction of the connecting cavity 11 to form a receiving groove 142.

[0059] With the above structure, the groove 142 provided on the riveting part 14 is located at the end of the connector 1 away from the head 13. During the connection process of the riveting part 14, the material of the external part will be squeezed into the groove, thereby preventing the connector 1 from coming out during the connection process.

[0060] This specification also provides a riveting pipe connector connection structure, including a riveting pipe connector, wherein the connecting part 12 is inserted into the rectangular tube 2 through the connecting hole, the head 13 abuts against the outer wall of the rectangular tube 2, and the riveting part 14 is riveted to the wall surface of the rectangular tube 2 away from the head 13; wherein, a plurality of guide holes 121 are connected to the inner cavity of the rectangular tube 2.

[0061] In this embodiment, those skilled in the art can insert the connector 1 into the rectangular tube 2, and the connector 1 has an internal thread in its connecting cavity 11, so that it can be connected to other parts.

[0062] Furthermore, in the connecting mechanism, the outer diameter of the head 13 is larger than the outer diameter of the connecting portion 12. The connector 1 passes through the connecting hole on the rectangular tube 2 and enters the inner cavity of the rectangular tube. A plurality of guide holes 121 are provided on the connecting cavity 11 of the connector 1. According to the above embodiment, the plurality of guide holes 121 form a hole group; one or more layers of hole groups are distributed at intervals along a direction perpendicular to the circumference of the connecting portion 12, and the plurality of guide holes 121 communicate with the connecting cavity 11.

[0063] With the above structure, the connecting cavity 11 can be connected to the inner cavity of the rectangular tube 2 through the guide hole 121, thereby enabling fluid to flow in the connecting cavity 11 and the inner cavity of the rectangular tube 2.

[0064] It is worth noting that those skilled in the art can set up a multi-layer hole group, so that the area of ​​fluid flowing from the cross section of the hole group is greater than the area of ​​the inner cavity of the rectangular tube 2, thereby ensuring that the installation of the connector 1 will not interfere with the flow of fluid inside the rectangular tube 2.

[0065] In a specific configuration, preferably, the head 13 has a connecting surface 131 on the side facing the connecting part, and a sealing groove 1311 is provided on the connecting surface 131; a sealing ring is installed in the sealing groove 1311 or filled with sealant, for sealing the connection between the head 13 and the rectangular tube 2.

[0066] With the above structure, the connection between the head 13 and the outer wall of the rectangular tube 2 can be sealed by installing a sealing ring or filling the sealing groove 1311 with sealant.

[0067] Specifically, the sealing strip is installed in the sealing groove 1311 and can abut against the wall of the sealing groove 1311 and the outer wall of the rectangular tube 2, thereby achieving a sealing effect. When filled with sealant, the sealant seals the connection between the connecting surface 131 where the sealing groove 131 is located and the outer wall of the rectangular tube 2.

[0068] In one embodiment, preferably, a first tooth 122 is provided at the connection between the connecting portion 12 and the head 13. The first tooth 122 is continuously distributed and closed along the circumference of the connecting portion 12. The first tooth 122 abuts against the outer wall of the rectangular tube and is embedded in the outer wall material of the rectangular tube 2.

[0069] With the above structure, when the connector 1 is connected, the head 13 abuts against other parts, and the first tooth 122 abuts against and is squeezed against the material of the rectangular tube 2 to form an interlocking structure.

[0070] During the extrusion process, the first tooth 122 forms an interlocking structure with the material of the outer wall of the rectangular tube 2, which ensures that the connector 1 will not fail to rotate after installation.

[0071] Specifically, when the connector 1 has a tendency to rotate, the edge of the first tooth 122 abuts and presses against the outer wall material of the rectangular tube 2, thereby preventing the first tooth 122 from rotating relative to the rectangular tube 2.

[0072] In the arrangement of the riveting part 14, preferably, the riveting part 14 is press-fitted to the inner wall of the rectangular tube 2, and the connecting cavity 11 is a through hole. In this embodiment, the riveting part 14 can be press-fitted to the wall surface of the rectangular tube 2 away from the head, thereby completing the connection of the connector 1.

[0073] In another embodiment, preferably, the riveting part 14 extends through the side wall of the rectangular tube 2 away from the head 13, and the riveting part 14 is riveted to the outer wall of the rectangular tube 2, with the connecting cavity 11 being a blind hole. In this embodiment, the connecting cavity 11 is set as a blind hole, and the riveting part 14 and the wall surface of the rectangular tube 2 away from the head can be riveted together, thereby completing the connection of the connector 1.

[0074] In the above embodiments, those skilled in the art can set the connecting cavity 11 as a through hole when the riveting part 14 is a press-fit structure, and set the connecting cavity 11 as a blind hole when the riveting part 14 is a flip-riveting structure, so that the connecting cavity 11 can be isolated from the outside world during the process of the riveting part 14 being connected to the rectangular tube in various ways.

[0075] In summary, by combining the connection method of the riveting part 14 with the opening method of the connecting cavity 11, the connector 1 can be used for connection in various situations, thereby improving the ease of use of the connector 1.

[0076] In a further embodiment of the riveting portion 14, preferably, a second tooth 141 is provided at the connection between the riveting portion 14 and the connecting portion 12. The second tooth 141 is continuously distributed and closed along the circumferential direction of the outer wall of the riveting portion 14, and the second tooth 141 is fitted into the material of the rectangular tube 2. The second tooth 141 is provided on the riveting portion 14 so that it can be fitted into the material of the rectangular tube 2, thereby improving the ability of the riveting portion 14 to prevent rotation after connection.

[0077] In another alternative embodiment, the riveting portion 14 is recessed at the connection point with the second tooth portion 141 toward the direction of the connecting cavity 11 to form a receiving groove 142, which is used to receive the material of the rectangular tube 2.

[0078] The groove 142 provided on the riveting part 14 is located at the end of the connector 1 away from the head 13. During the connection process of the riveting part 14, the material of the rectangular tube 2 will be squeezed into the groove 142, thereby preventing the connector 1 from coming out during the connection process.
