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.

[0023] Example 1, by Figure 1 The present invention relates to a low-temperature resistant dustproof rubber sealing ring, comprising an installation ring 1, with sealing rings 3 fixedly connected to both ends of the installation ring 1, and sealing rings 4 fixedly connected to the sides of the two sealing rings 3 that are far apart from each other. An elastic mechanism 2 is provided on the outer side of the installation ring 1.

[0024] Specifically, by Figure 2-3 The elastic mechanism 2 includes multiple upright frames 201 equidistantly located outside the mounting ring 1. Two abutment rings 204 are symmetrically arranged on the outer side of the mounting ring 1, abutting against the sides of two sealing rings 3 that are close to each other. Two movable columns 206 are symmetrically and movably sleeved inside the upright frames 201. The ends of the two movable columns 206 that are far apart from each other are fixedly connected to the two abutment rings 204. A spring 205 is fixedly connected between the abutment rings 204 and the upright frames 201, and the spring 205 is sleeved on the outer side of the movable columns 206. A sleeve frame 202 is fixedly sleeved on the outer side of the upright frames 201, and an outer ring 203 is fixedly sleeved on the outer side of the mounting ring 1. The sleeve frame 202 and the outer ring 203... Two reinforcing columns 2011 are symmetrically fixedly connected between the three parts. A sliding plate 2010 is provided between the sleeve frame 202 and the outer ring 203. The sliding plate 2010 is movably sleeved on the outside of the two reinforcing columns 2011. Two springs 209 are symmetrically fixedly connected between the sliding plate 2010 and the sleeve frame 202. The two springs 209 are respectively sleeved on the outside of the two reinforcing columns 2011. A sliding groove 208 is provided on the outside of the upright frame 201. A slider 207 is fixedly connected to the outside of the movable column 206. The slider 207 is slidably connected to the sliding groove 208. A drive rod 2012 is rotatably connected to the outside of the slider 207. The end of the drive rod 2012 away from the slider 207 is rotatably connected to the sliding plate 2010.

[0025] In use, when the sealing ring 4 is compressed, the pressure is applied to the abutment ring 204 through the sealing ring 3, causing the movable column 206 to slide along the upright frame 201. At this time, the first spring 205 is compressed, and the slider 207 slides along the slide groove 208. Then, the drive rod 2012 drives the slide plate 2010 to slide along the reinforcing column 2011. At this time, the second spring 209 is stretched, and under the action of the elastic force of the second spring 209 and the first spring 205, the sealing ring 4 is tightly fitted with the contact surface, improving the sealing performance of the entire rubber sealing ring.

[0026] Specifically, by Figure 4 It is provided that the sealing ring 3 has a sealing protrusion 5 on the side away from the mounting ring 1. The sealing protrusion 5 is integrally formed with the mounting ring 1. The sealing protrusion 5 is located inside the sealing ring 4.

[0027] In use, when the contact surface applies pressure to the sealing ring 4, the spring 205 and the spring 209 deform until the contact surface is tightly against the sealing protrusion 5. The sealing ring 4 and the sealing protrusion 5 provide a double seal, ensuring the sealing effect of the entire rubber sealing ring.
