Description

Technical Field

[0001] This utility model belongs to the field of sealing ring technology, specifically a modular sealing ring structure with adjustable sealing diameter. Background Technology

[0002] A sealing ring is an elastic device used to prevent the leakage of liquids or gases. It is usually made of materials such as rubber, silicone, and metal, and is widely used in machinery, automobiles, electronics and other fields. It is a ring-shaped device made of elastic material that achieves a sealing effect through contact or gap structure. Its main functions include preventing lubricating oil leakage, preventing foreign matter intrusion, and maintaining system pressure balance.

[0003] In existing technologies, traditional sealing rings are mostly integral structures with a fixed sealing diameter. Once the size of the sealing surface changes, it is necessary to replace the sealing ring with one of the corresponding specifications, which not only increases the cost of spare parts but also reduces the efficiency of equipment maintenance.

[0023] 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.

[0024] Example 1, by Figure 1 The present invention relates to a modular sealing ring structure with adjustable sealing diameter, comprising a metal ring 1, wherein a sealing mechanism 2 is provided on the top of the metal ring 1.

[0025] Specifically, by Figure 2-4 The sealing mechanism 2 includes a conical cylinder 201 fixed to the top of the metal ring 1. A top ring 203 is fixedly connected to the top of the conical cylinder 201. The top of the top ring 203 has multiple annular grooves 208, and each annular groove 208 contains a retaining ring 209. A rubber ring 204 with different diameters is fixedly connected to the top of each retaining ring 209. Bottom blocks 205 are fixedly connected to both sides of the bottom of each retaining ring 209, and the bottom blocks 205 penetrate the top ring 203. Two support frames 2011 are symmetrically fixedly connected between the top ring 203 and the metal ring 1. The bottom of the base block 205 extends into the support frame 2011. A guide rod 2013 is fixedly connected between the support frame 2011 and the metal ring 1. A guide plate 2012 is movably sleeved on the outside of the guide rod 2013. An arc plate 202 is fixedly connected to the outside of the guide plate 2012. A limit frame 2010 is fixedly connected to the top of the guide plate 2012. A limit groove 206 is provided on the base block 205. A limit rod 207 is fixedly connected to the inside of the limit groove 206. The limit frame 2010 is inserted into the limit groove 206 and is sleeved on the outside of the limit rod 207.

[0026] In use, first select the required rubber ring 204, place its bottom retaining ring 209 into the corresponding annular groove 208, and simultaneously, the two bottom blocks 205 at the bottom of the retaining ring 209 pass through the top ring 203 and extend into the two support frames 2011 respectively. Then, push the arc plate 202, causing the two guide plates 2012 to slide along the two guide rods 2013 respectively, and causing the two limit frames 2010 to move, so that the limit frame 2010 fits on the outside of the limit rod 207 and inserts into the limit groove 206, limiting the bottom block 205 and realizing the installation of the rubber ring 204. Finally, adjust the sealing diameter of the sealing ring according to the requirements.

[0027] Specifically, by Figure 5 As shown, an L-shaped round rod 2014 is fixedly connected to the outer side of the arc plate 202. A top plate 2018 is fixedly connected to the top of the L-shaped round rod 2014. A threaded column 2017 is fixedly connected to the bottom of the top plate 2018.

Then, the screw barrel 2016 is rotated so that it moves on the threaded post 2017 and the semi-circular threaded rod 2020 until the screw barrel 2016 abuts against the bottom of the support plate 2019, connecting the semi-circular threaded rod 2020 to the threaded post 2017, thereby limiting the arc plate 202 to prevent it from moving. Finally, the required rubber ring 204 is fixed.
