Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flange parts, in particular to a thin-wall flange with an integrated sealing gasket. Background Art
[0002] During the assembly process of automobile exhaust pipes, flange structures are often used. The inner hole of the flange is used to be sleeved onto the exhaust pipe, and then the two flanges are fastened with bolts to achieve the connection between the exhaust pipes.
[0003] While existing flanges can connect exhaust pipes, the gap between the two flanges lacks sealing. Over time, the pipes will leak, impacting performance. To address this issue, a common practice is to insert a sealing ring between the two connecting flanges. However, in practice, adding a sealing ring between the two flanges not only makes assembly difficult, but also tends to shift relative to the flanges over time, leading to seal failure. Utility Model Content
[0004] The utility model aims to solve the problem in the prior art that adding a sealing ring to a flange is not only difficult to assemble, but also that the sealing ring is easily offset relative to the flange as the service time increases, resulting in sealing failure.
[0005] In order to solve the above problems, the utility model provides a thin-walled flange with an integrated sealing gasket, including an annular sealing gasket and a flange body with an inner hole, the flange body is provided with at least two clamping holes distributed circumferentially around the inner hole, the sealing gasket is attached to one side of the flange body and arranged around the inner hole, and the side of the sealing gasket facing the flange body is provided with ears that are respectively clamped to the clamping holes.
[0006] Compared with the existing technology, the above scheme sets circumferentially distributed clamping holes around the inner hole on the flange body, and can pre-realize the assembly connection between the sealing gasket and the flange body by clamping the clamping ears of the sealing gasket to the clamping holes. Therefore, when the two flange bodies need to be docked later, it not only effectively reduces the assembly difficulty, but also improves the position stability of the sealing gasket between the two flange bodies, thereby ensuring the sealing effect.
[0007] In an improved solution, the sealing gasket is made of metal, thereby having better durability.
[0008] In an improved solution, mounting holes are respectively provided at both ends of the flange body, and the mounting holes are used for assembly with bolts, thereby achieving connection between the two flange bodies.
[0009] In an improved solution, through holes corresponding to the mounting holes are respectively provided at both ends of the sealing gasket, so that after bolts are installed in the mounting holes, the bolts can also pass through the through holes to tighten the sealing gasket.
[0010] In an improved solution, there are two clamping holes, and the two clamping holes are respectively arranged adjacent to the two mounting holes, so that the layout is more reasonable.
[0011] In an improved solution, the two clamping holes are respectively located on both sides of a virtual line connecting the two mounting holes, thereby improving the connection stability between the sealing gasket and the flange body.
[0012] In an improved solution, a convex ring is provided on the side of the sealing gasket facing away from the flange body, and the convex ring is arranged around the inner hole. During assembly, the sides of the two flange bodies with the sealing gaskets are opposite to each other, thereby achieving a better sealing effect through the convex ring on the sealing gasket.

[0017] It should be understood by those skilled in the art that the following embodiments are merely intended to explain the technical principles of the embodiments of the present application and are not intended to limit the scope of protection of the embodiments of the present application. Those skilled in the art may adjust them as needed to suit specific applications.
[0018] In the following descriptions of the embodiments, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of this application based on the specific circumstances.
[0019] In the embodiments of the present application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, a first feature being "above," "above," and "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
[0020] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0021] See also Figure 1 and Figure 2 An embodiment of the present invention provides a thin-walled flange with an integrated sealing gasket, comprising an annular sealing gasket 2 and a flange body 1 having an inner hole 11. The flange body 1 is provided with at least two clamping holes 12 distributed circumferentially around the inner hole 11. The sealing gasket 2 is attached to one side of the flange body 1 and arranged around the inner hole 11. The side of the sealing gasket 2 facing the flange body 1 is provided with clamping ears 21 that are respectively clamped to the clamping holes 12.
[0022] The above scheme can pre-realize the assembly connection between the sealing gasket 2 and the flange body 1 by providing the clamping holes 12 distributed circumferentially around the inner hole 11 on the flange body 1, and by clamping the clamping ears 21 of the sealing gasket 2 to the clamping holes 12. Therefore, when the two flange bodies 1 need to be docked later, it not only effectively reduces the assembly difficulty, but also improves the position stability of the sealing gasket 2 between the two flange bodies 1, thereby ensuring the sealing effect.
[0023] In this embodiment, the sealing gasket 2 is preferably made of metal to provide good durability. Of course, in other embodiments, it can also be made of rubber or plastic, and this design is not limited to this. Furthermore, the side of the sealing gasket 2 facing away from the flange body 1 is provided with a raised ring 23. The raised ring 23 is arranged around the inner hole 11. When assembled, the sides of the two flange bodies 1 with the sealing gaskets 2 facing each other, thereby achieving a better sealing effect through the raised ring 23 on the sealing gasket 2.
[0024] The flange body 1 has mounting holes 13 at both ends for bolt assembly, thereby achieving a connection between the two flange bodies 1. In this embodiment, the sealing gasket 2 has through holes 22 at both ends corresponding to the mounting holes 13. After the bolts are installed in the mounting holes 13, the bolts can also pass through the through holes 22 to tighten the sealing gasket 2.
[0025] The number of the clamping holes 12 in this embodiment is preferably two, and the two clamping holes 12 are respectively arranged adjacent to the two mounting holes 13, so that the layout is more reasonable. Further, the two clamping holes 12 are respectively located on both sides of the virtual line connecting the two mounting holes 13, as shown in FIG. Figure 1 As a reference, the two mounting holes 13 are respectively located at the left and right ends of the flange body 1, and the two clamping holes 12 are respectively located at the upper left and lower right positions of the sealing gasket 2, so that the connection stability between the sealing gasket 2 and the flange body 1 is better.
[0026] Of course, the number of the clamping holes 12 on the flange body 1 can also be increased or decreased, and the same is true for the number of the clamping ears 21 on the sealing gasket 2. This design does not impose any limitation on this.
