[0020] See also Figures 1 to 3 A silicone sealing pad with a built-in spring shell, the shell 1 is provided with a through hole 2, the through hole 2 is arc-shaped, and a bottom plate is provided, a through hole 21 for the end of the variable damping spring to extend out is opened at the bottom plate, and a limit rod 5 is provided at the through hole 2.

[0021] A silicone sealing gasket in the present embodiment includes a first clamping portion 3 and a second clamping portion 4 which cooperate with the through hole 2, wherein the first clamping portion 3 and the second clamping portion 4 can be integrally arranged, or the first clamping portion 3 and the second clamping portion 4 can be separately arranged, and the second clamping portion 4 is arc-shaped or semicircular. The separate arrangement or the integrated arrangement of the first clamping portion 3 and the second clamping portion 4 is more convenient for the division of labor production of the silicone sealing gasket, and during the installation process, it is helpful to distinguish which side is the first clamping portion 3 and which side is the second clamping portion 4, that is, the clamping portions can be more efficiently and accurately embedded into the through hole 2.

[0022] A step is provided between the first clamping part 3 and the second clamping part 4 of the embodiment, and the step corresponds to the through hole 2 of the shell 1. The second clamping part 4 is provided with a limiting groove 6 that matches the limiting rod 5; the limiting rod 5 is arc-shaped, and the limiting groove 6 is correspondingly set to an arc shape. Two limiting strips 10 are provided on the side of the limiting rod 5, and the second clamping part 4 is provided with a limiting groove 11 corresponding to the limiting strip 10. Two limiting strips 10 are provided on the side of the limiting rod 5, and the second clamping part 4 is provided with a limiting groove 11 corresponding to the limiting strip 10. On the basis of setting the limiting rod 5 and the limiting groove 6, a limiting strip 10 and a limiting groove 11 are further provided, thereby achieving the purpose of further limiting clamping and achieving a higher degree of fixing firmness.

[0023] In order to better limit the position in the horizontal direction, a positioning rod 7 is provided on the inner wall of the through hole 2 of the shell 1 in this embodiment, and a positioning groove 8 matching the positioning rod 7 is provided on the second clamping part 4. Through the close cooperation between the positioning rod 7 and the positioning groove 8, on the one hand, the firmness between the two can be improved to achieve a higher anti-slip rate. On the other hand, during the clamping process, it can be clamped into the through hole 2 along the angle of the positioning groove 8, thereby avoiding deformation of the first clamping part 3 to a large extent.

[0024] The second clamping part 4 is provided with a clamping hole 9, and the end of the spring passes through the clamping hole 9 and the two are tightly fitted. In order to facilitate the removal of the second clamping part 4, the first clamping part 3 can also be removed conveniently. The end of the spring first passes through the through hole 21 on the bottom plate, and then passes through the clamping hole 9. In addition, the bottom of the first clamping part 3 is provided with a protrusion,

[0025] The use effect is as follows: the silicone sealing gasket is clamped at the through hole 2 of the shell 1, and the gap between the through hole 2 and the end of the variable damping spring and the through hole 2 is sealed, thereby improving the sealing performance between the two. At the same time, for the through hole 2 of the shell 1 with poor sealing performance, after adopting the utility model, there is no need to use additional sealing parts to seal the through hole 2 again, and it is not easy to cause the shell 1 to be damaged due to poor sealing. In the later use process, the integrity of the shell 1 and the variable damping spring is better, thereby improving the service life.
