本实施例中，由于壳体31的厚度大于第一密封件32和第二密封件33的厚度，这样可以尽量避免壳体31上与圆弧结构43的连接处产生应力集中，从而尽可能延长第一密封环3甚至是整个密封组件的使用寿命。In this embodiment, since the thickness of the housing 31 is greater than the thickness of the first sealing member 32 and the second sealing member 33, it is possible to avoid stress concentration at the junction of the housing 31 and the arc structure 43 as much as possible, thereby extending the The first sealing ring 3 is even the service life of the entire sealing assembly.
可选地，第一连接部44的厚度(图1中所示的X4)大于第一连接件41的厚度(图1中所示的X5)；第二连接部45的厚度(图1中所示的X6)大于第二连接件42的厚度(图1中所示的X7)。Optionally, the thickness of the first connecting portion 44 (X4 shown in FIG. 1 ) is greater than the thickness of the first connecting member 41 (X5 shown in FIG. 1 ); the thickness of the second connecting portion 45 (X4 shown in FIG. 1 X6 shown) is greater than the thickness of the second connecting member 42 (X7 shown in FIG. 1).
本实施例中，由于第一连接部44的厚度X4大于第一连接件41的厚度X5，第二连接部45的厚度X6大于第二连接件42的厚度X7，因此，第二密封环4通过第一连接部44施加的弹性压紧力能够有效地传递至第一翻边34，第二密封环4通过第二连接部45施加的弹性压紧力能够有效地传递至第二翻边35，从而有效地实现密封组件的自紧。In this embodiment, since the thickness X4 of the first connecting part 44 is greater than the thickness X5 of the first connecting part 41, and the thickness X6 of the second connecting part 45 is greater than the thickness X7 of the second connecting part 42, the second sealing ring 4 passes The elastic pressing force applied by the first connecting portion 44 can be effectively transmitted to the first flange 34 , and the elastic pressing force applied by the second sealing ring 4 through the second connecting portion 45 can be effectively transmitted to the second flange 35 , Thereby, the self-tightening of the sealing assembly is effectively realized.
综上，本发明实施例能够在保证密封组件密封效果的前提下，降低密封组件的生产成本。To sum up, the embodiments of the present invention can reduce the production cost of the sealing assembly on the premise of ensuring the sealing effect of the sealing assembly.
