[0031] Reference Figure 1 As shown, this application embodiment provides a sealing riveting structure, including:

[0032] A connector 1 with a central axis has a main body 11. One end of the main body 11 is fixedly connected to a flange 12. The flange 12 has a receiving groove 121 on the end side facing the main body 11. A connecting surface is provided on the outer wall of the main body 11 near the flange 12.

[0033] The plate 2 is fitted onto the connecting surface. The inner wall of the plate 2 abuts against the outer wall of the connector 1, and the wall of the connector 1 is deformed in the direction away from the central axis to form a stop 112. The stop 112 abuts against the side wall of the plate 2 away from the flange 12, and the plate 2 abuts against the outer wall of the flange 12.

[0034] The connecting surface 14 is inclined and the material of the connecting surface 14 is pressed against the material of the plate 2 toward the outer wall of the flange portion 12, so that the material of the plate 2 toward the outer wall of the flange portion 12 is pressed into the trough 121 to form a sealing structure.

[0035] according to Figure 1 and Figure 2 Those skilled in the art can configure the connector 1 to consist of a main body 11 and a flange 12. The flange 12 is fixedly connected to one end of the main body 11, and the outer diameter of the flange 12 is larger than the outer diameter of the main body 11.

[0036] Furthermore, those skilled in the art can provide a connecting surface 14 on the outer wall of the main body 11 near the flange 12, so that the plate 2 can be fitted onto the connecting surface 14. That is, the plate 2 is fitted onto the outer wall of the main body 1, and the inner wall of the plate 2 abuts against the connecting surface.

[0037] Furthermore, those skilled in the art can deform the wall surface of the main body 1 in a direction away from the central axis to form a stop 112. The stop 112 abuts against the side wall of the plate 2 away from the flange 12, and the plate 2 abuts against the outer wall of the flange 12 towards the plate 2.

[0038] With the above structure, those skilled in the art can provide a baffle 112 formed by deformation on the outer wall of the main body 11. The relative position of the plate 2 is fixed by the baffle 112 and the flange 12.

[0039] It is understood that those skilled in the art can provide a receiving groove 121 on the end side of the flange portion 12 facing the main body portion 11. While the baffle 112 is formed by deformation on the outer wall of the main body portion 11, the baffle 112 will squeeze the plate 2, causing the material on the side of the plate 2 facing the flange portion 12 to be squeezed into the receiving groove 121.

[0040] According to the process described above, the material of the plate 2 facing the flange 12 is squeezed into the receiving groove 121, which allows the material of the plate 2 to come into contact with the receiving groove 121, thereby forming a sealing structure. Specifically, in this embodiment, those skilled in the art can set the connecting surface 14 as an inclined surface, and more preferably, the connecting surface 14 can be set as an inclined conical surface. During the riveting process, the stop 112 squeezes the plate 2 to generate an axial clamping force, and the material of the plate 2 is squeezed against the connecting surface 14, thereby allowing the material of the plate 2 to flow into the receiving groove 121 under the squeezing action of the connecting surface 14.

[0041] With the above-mentioned sealing structure, the sealing effect between the plate 2 and the flange 12 can be significantly improved after the plate 2 is connected to the connector 1.

[0042] In the above structure, the wall surface of the baffle 112 that abuts against the plate 2 can be sealed, and the material on the side of the plate 2 facing the flange 12 that is squeezed into the receiving groove 121 can also be sealed, so that both sides of the plate 2 that are in contact with each other can be sealed after connection. Specifically, the plate 2 and the connecting surface are interference fit, so that the material can flow into the receiving groove 121 during the extrusion process.

[0043] In summary, those skilled in the art can configure the wall surface of the main body 1 to deform in a direction away from the central axis to form a baffle 112. The baffle 112 abuts against the side wall of the plate 2 away from the flange 12, and the plate 2 abuts against the outer wall of the flange 12. A receiving groove 121 is provided on the end side of the flange 12 facing the main body 11. While the baffle 112 is deformed on the outer wall of the main body 11, the baffle 112 will squeeze the plate 2, so that the material on the side of the plate 2 facing the flange 12 is squeezed into the receiving groove 121, thereby enabling the plate 2 to have a sealing ability after connection.

[0044] In the above structure, a receiving groove 121 is provided on the end side of the flange portion 12 facing the main body portion 11. The receiving groove 121 accommodates the material of the plate 2, thereby achieving significant sealing performance after the plate 2 is connected. Preferably, the receiving groove 121 extends and closes along the circumference of the side wall of the flange portion 12 facing the plate.

[0045] That is, those skilled in the art can set the groove 121 as an annular groove that extends and closes along the side wall of the flange 12 toward the plate, so that the plate 2 can form a sealed structure around the connection with the flange 12, thereby further significantly improving the sealing performance of the connection between the plate 2 and the flange 12.

[0046] In the above-described configuration, the plate 2 abuts against the side wall of the flange 12 facing the plate 2. Preferably, a plurality of protrusions 122 are fixedly connected to the side wall of the flange 12 facing the plate 2, and the plurality of protrusions 122 are pressed into the material of the plate 2 facing the flange 12.

[0047] Specifically, those skilled in the art can fix multiple protrusions 122 on the side wall of the flange 12 facing the plate 2. During the process of the plate 2 and the flange 12 being pressed and abutted, the multiple protrusions 122 can be pressed into the plate 2.

[0048] With the above structure, after the multiple protrusions 122 are squeezed into the plate 2, the material in the plate 2 and the protrusions 122 come into contact with each other to form a blocking structure.

[0049] It is understandable that in the above-mentioned blocking structure, when the plate 2 has a tendency to rotate after being connected, the material of the plate 2 and the protrusion 122 will collide and press against each other, and the protrusion 122 will prevent the plate 2 and the connector 1 from rotating relative to each other.

[0050] More preferably, the multiple protrusions 122 are evenly spaced. That is, those skilled in the art can significantly improve the stability of the connection between the plate 2 and the connector 1 by using the evenly distributed multiple protrusions 122. At the same time, the evenly spaced multiple protrusions 122 make the force distribution among the multiple protrusions 122 more uniform.

[0051] In an optional embodiment, preferably, an anti-slip portion 111 is provided on the connecting surface. In the above embodiment, the plate 2 is fitted onto the connecting surface, so that the inner wall of the plate 2 can abut against the anti-slip portion 111.

[0052] It is understood that those skilled in the art can design the anti-slip part 111 as a plurality of vertical stripes, so that the anti-slip part 111 can fit into the plate 2 during the process of the inner wall of the plate 2 against the anti-slip part 111, thereby forming an anti-slip structure.

[0053] In summary, those skilled in the art can configure the flange portion 12 to have multiple protrusions 122 fixedly connected to the side wall facing the plate 2, the multiple protrusions 122 being pressed into the material of the plate 2 facing the flange portion 12, the multiple protrusions 122 being evenly spaced and the connection surface being provided with anti-slip parts 111, thereby preventing the plate 2 from rotating relative to each other after the connection is completed.

[0054] For riveting the sheet metal 2 and connecting the connector 1 to external parts, preferably, the main body 11 is provided with a blind hole 13, and the blind hole 13 is provided with an internal thread. The internal thread in the blind hole 13 enables the riveting of the sheet metal 2 and the connection of the connector 1.

[0055] This specification also provides a connector, including:

[0056] Main body 11;

[0057] A flange 12 is fixedly connected to one end of the main body 11, and a groove 121 is provided on the side of the flange 12 facing the main body 11.

[0058] The trough 121 extends and closes along the flange portion 12 toward the side wall of the plate 2.

[0059] That is, those skilled in the art can configure the connector 1 to consist of a main body 11 and a flange 12 fixedly connected to one end of the main body 11. Further, a receiving groove 121 is provided on the side of the flange 12 facing the main body 11, and the receiving groove 121 extends and closes along the periphery of the side wall of the flange 12 facing the plate 2.

[0060] With the above structure, by providing the receiving groove 121, a sealing mechanism can be formed during the connection process of the connector 1, thereby making the connector 1 have a sealing property in the connection mechanism.

[0061] In a specific connection structure, preferably, a connecting surface is provided on the outer wall of the main body 11 near the flange 12, and an anti-slip part 111 is provided on the connecting surface. The anti-slip part 111 can prevent relative sliding between the external part and the connecting part 1 after the connecting part 1 is connected.

[0062] In an alternative embodiment, preferably, a plurality of protrusions 122 are fixedly connected to the side wall of the flange portion 1 facing the main body portion 1. The plurality of protrusions 122 can be fitted into the materials being connected during the connection process, thereby forming a structure that prevents rotation.

[0063] To enable the connector 1 to be connected, those skilled in the art can provide a blind hole within the main body, and the blind hole has an internal thread. Through the internal thread in the blind hole, the connector 1 can be riveted and connected to external parts.
