Problems solved by technology

[0002] In engineering practice, sealing problems are often encountered. Traditional seals can only complete the sealing of one surface (using O-rings, lip rings, flat gaskets, etc.). , if a combination of multiple seals is used, not only will the sealing structure be complex and heavy, but the replacement process of the sealing ring will be cumbersome and time-consuming during maintenance.

Embodiment 1

[0019] image 3 A specific example of the installation of the sealing ring provided by the present invention on the outer door panel 5 is used to complete the sealing of the two surfaces between the outer door panel 5 and the inner door panel 6 and the outer flange 7 respectively, and the ring groove of the sealing ring fixing structure Located on the inner side of the seal body. The top and bottom of the outer side of the sealing ring body are sealing surfaces, and the sealing ring is respectively arranged with a sealing wing structure on the outer slope and the bottom. In the free state, the inclined plane sealing wings protrude from the inclined plane sealing surface, and there is a groove at the root of the wing. The length of the wing is subject to the fact that the sealing wing does not protrude from the top surface after being folded, otherwise, the sealing wing will form a "bridge" on the inclined sealing surface. The bottom edge sealing wing protrudes from the botto...

Embodiment 2

[0022] like Figure 4 As shown, another embodiment of the present invention is to install the sealing ring 4 on the inner flange 8 to complete the sealing between the inner flange 8 and the inner door panel 6 and the outer flange 7 respectively. The annular groove of the ring fixing structure is located on the outer side of the sealing ring body. The lower part of the inner side and the top side of the sealing ring body are sealing surfaces, and the sealing ring is respectively arranged with a sealing wing structure on the inner slope and the top side. In the free state, the inclined plane sealing wings protrude from the inclined plane sealing surface, and there is a groove at the root of the wing. The sealing wing on the top edge protrudes from the top surface of the sealing ring, and there is also a groove at the root of the wing. After the sealing wing is folded, it does not protrude from the sealing surface of the inner slope.

Abstract

The invention relates to a sealing ring with a sealing-wing structure. The sealing ring comprises a sealing ring body. A sealing-ring fixing structure is arranged inside or outside the sealing ring body, wing structures are arranged on sealing surfaces of the sealing ring body, one side of each wing structure protrudes out of each sealing surface and upwarps outwardly, and a groove is formed in the root of each wing structure. When the sealing ring is pressed against a corresponding sealing component, sealing wings are pressed to be folded from a free state of protruding out of the sealing surfaces, sealing force is provided by bending deflection generated from folding of the sealing wings, and tips of the sealing wings are forced to be squeezed to generate deflection used for sealing. By the sealing-wing structure, a plurality of surfaces can be sealed simultaneously.

Description

technical field [0001] The invention belongs to the structural design of a sealing ring, in particular to a sealing ring which utilizes a sealing wing structure to complete multiple surface sealing functions. Background technique [0002] In engineering practice, sealing problems are often encountered. Traditional seals generally can only complete the sealing of one surface (using O-rings, lip rings, flat gaskets, etc.). However, if a combination of multiple seals is used, not only will the sealing structure be complicated and thick, but also the process of replacing the seal ring will be cumbersome and time-consuming during maintenance. Therefore, there is an urgent need for a sealing ring capable of sealing multiple surfaces and having a simple and reliable structure. Contents of the invention [0003] The purpose of the present invention is to provide a sealing ring with a sealing wing structure suitable for multiple surface sealing applications. [0004] The technica...
