[0019] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0020] Example 1

[0021] like Figure 3 As shown, this embodiment discloses a double-reinforced metal C-type sealing ring, which includes a first sealing ring body 1 and a second sealing ring body 2. The first sealing ring body 1 and the second sealing ring body 2 are both annular, and the first sealing ring body 1 and the second sealing ring body 2 are connected together up and down through an intermediate connecting part 5, so that the first sealing ring body 1 and the second sealing ring body 2 are coaxially arranged.

[0022] The first sealing ring body 1 and the second sealing ring body 2 are both hollow structures, and both are provided with openings 3 communicating with the internal cavity, so that the cross-sections of the first sealing ring body 1 and the second sealing ring body 2 are in a "C" shape. In addition, an elastic member 6 is provided inside the first sealing ring body 1 and / or the second sealing ring body 2, and the elastic member 6 can be installed into the first sealing ring body 1 and / or the second sealing ring body 2 from the position of the opening 3, such as Figure 4 shown.

[0023] In addition, in the specific implementation, the elastic member 6 can be a spring ring, a rubber ring, a polytetrafluoroethylene ring or a wire winding ring. The elastic member 6 in this embodiment is implemented by a spring ring, and the elastic member 6 is arranged in the first sealing ring body 1 and the second sealing ring body 2.

[0024] In a specific implementation, the opening 3 faces the center line of the double reinforced metal C-shaped sealing ring, that is, the openings 3 on the first sealing ring body 1 and the second sealing ring body 2 face the center of the first sealing ring body 1 and the second sealing ring body 2 respectively. Figure 3 In addition, the opening 3 may also be oriented away from the center line of the double reinforced metal C-shaped sealing ring, that is, the openings 3 on the first sealing ring body 1 and the second sealing ring body 2 are oriented away from the center of the first sealing ring body 1 and the second sealing ring body 2, respectively. Figure 6 Alternatively, the opening 3 faces the side away from the middle connecting portion 5, that is, the opening 3 on the first sealing ring body 1 faces upward, while the opening 3 on the second sealing ring body 2 faces downward.

[0025] The double-reinforced metal C-shaped sealing ring of the present embodiment is configured with a first sealing ring body 1 and a second sealing ring body 2 as a double-layer design connected together up and down, so that the double-reinforced metal C-shaped sealing ring of the present embodiment is suitable for deep and narrow sealing grooves, such as Figure 5 In addition, elastic members 6 are provided in both the first sealing ring body 1 and the second sealing ring body 2, which can well increase the strength of the double-reinforced metal C-shaped sealing ring and improve the sealing performance.
