[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example 1, by Figure 1 The present invention relates to a sealing gasket, comprising an aluminum sheet 1, a rubber sheet 3 fixedly connected to the outer side of the aluminum sheet 1, and an elastic mechanism 2 provided on the rubber sheet 3.

[0022] Specifically, by Figures 2-3 The elastic mechanism 2 includes a mounting ring 201 fixed to the side of the rubber sheet 3 away from the aluminum sheet 1. An outer ring 203 is provided between the mounting ring 201 and the aluminum sheet 1, located outside the rubber sheet 3. Multiple support columns 202 are fixedly connected at equal angles between the outer ring 203 and the aluminum sheet 1. A sliding plate 207 is movably sleeved on the outer side of each support column 202. A spring 206 is fixedly connected between the sliding plate 207 and the outer ring 203, sleeved on the outer side of the support column 202. A connecting column 205 is fixedly connected between the sliding plate 207 and the mounting ring 201, penetrating the outer ring 203 and movably connected to it. The mounting ring 201 is located away from the rubber sheet 3. Multiple annular rubber pads 204 are fixedly connected to one side. Each annular rubber pad 204 has wear-resistant particles on the side away from the mounting ring 201. A guide rod 208 is fixedly connected between the support column 202 and the aluminum sheet 1. The guide rod 208 is located below the slide plate 207. A guide block 2011 is movably sleeved on the outside of the guide rod 208. A movable rod 2014 is rotatably connected to the top of the guide block 2011. The top of the movable rod 2014 is rotatably connected to the slide plate 207. A fixing ring 209 is fixedly sleeved on the outside of the guide rod 208. A spring 2010 is fixedly connected between the fixing ring 209 and the guide block 2011. The spring 2010 is sleeved on the outside of the guide rod 208.

[0023] In use, multiple annular rubber pads 204 are set on the mounting ring 201 to form multiple seals. Wear-resistant particles are set on the annular rubber pads 204 to improve the wear resistance of the entire sealing gasket and reduce seal failure caused by friction. When the annular rubber pads 204 are squeezed by the contact body, they drive the mounting ring 201 to move. The connecting column 205 drives the sliding plate 207 to slide along the support column 202. At this time, the first spring 206 is stretched. Then, the movable rod 2014 drives the guide block 2011 to slide along the guide rod 208. At this time, the second spring 2010 is stretched, so that the annular rubber pads 204 are tightly fitted with the contact body under the elastic force of the first spring 206 and the second spring 2010, and finally improve the sealing effect of the entire sealing gasket.

[0024] Specifically, by Figure 3 As shown, the top of the guide block 2011 is fixedly connected to the limiting plate 2012, and the outer ring 203 is provided with a limiting groove 2013, and the limiting plate 2012 and the limiting groove 2013 are slidably connected.

[0025] In use, when the annular rubber pad 204 is squeezed by the contact body, the guide block 2011 slides along the guide rod 208, and the limiting plate 2012 slides along the limiting groove 2013 to limit the guide block 2011, thus ensuring the stability of the guide block 2011 when it slides on the guide rod 208.
