Description

Technical Field

[0001] This utility model relates to the field of rubber sealing ring technology, and in particular to a detachable sealing ring structure. Background Technology

[0002] A sealing ring is a sealing element that prevents leakage of fluids or solid particles, as well as the intrusion of external impurities. It achieves its sealing function by filling gaps through elastic deformation. It is widely used in machinery manufacturing, automotive industry, aerospace, chemical equipment, and other fields, and is a key component for ensuring the normal operation of equipment and preventing media leakage.

[0003] Most existing sealing rings are made of a single rubber material or a combination of rubber and a simple skeleton, and are installed in the sealing area by interference fit or adhesive bonding. Their structure is relatively fixed, and they mainly rely on the elasticity of the rubber itself to achieve a seal.

[0004] The current design of sealing rings using a single material makes them prone to deformation and aging during long-term use or when facing complex working conditions such as high pressure and high temperature. This leads to a gradual decline in sealing performance and makes them unable to meet the needs of high-requirement sealing scenarios. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a detachable sealing ring structure, which aims to improve the problems of lack of support skeleton, easy damage and difficulty in maintaining sealing performance in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A detachable sealing ring structure includes an outer ring and an inner ring, wherein a fixing component is installed inside the outer ring and a disassembly component is installed on the top of the inner ring;

[0008] The fixing component includes a first reinforcing steel, which is installed inside the outer ring. The first reinforcing steel is rotatably connected to a second reinforcing steel via a rotating shaft. A round rod is fixedly connected to the top of both the first and second reinforcing steels, and a spring is fixedly connected between the two round rods.

[0009] As a further description of the above technical solution:

[0010] The disassembly assembly includes a storage slot, which is located at the top of the inner ring. A handle is rotatably connected inside the storage slot, and two rotating rods are fixedly connected to both ends of the handle. Both rotating rods are rotatably connected inside the storage slot.

[0011] As a further description of the above technical solution:

[0012] One end of the second reinforcing steel is provided with a circular groove, and one end of the first reinforcing steel is fixedly connected with a protrusion, the protrusion and the circular groove are engaged with each other;

[0013] As a further description of the above technical solution:

[0014] An upper protective film is installed on the top of the outer ring, and the upper protective film is located above the second reinforcing steel and the first reinforcing steel;

[0015] As a further description of the above technical solution:

[0016] The upper protective film has a groove inside, and the round rod is slidably connected inside the groove.

[0017] As a further description of the above technical solution:

[0018] A lower protective film is installed at the bottom of the outer ring, and the lower protective film is circular.

[0019] As a further description of the above technical solution:

[0020] The top of the outer ring is provided with a flow guide groove, and the outer side of the outer ring is provided with an installation groove;

[0021] As a further description of the above technical solution:

[0022] A groove is provided on the outer side of the inner ring, and both the second reinforcing steel and the first reinforcing steel are installed inside the groove.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the second reinforcing steel reinforces the outer and inner rings of the sealing ring, ensuring structural stability. During disassembly, pulling the round rod elongates the spring, and the spring's restoring force loosens the first and second reinforcing steels, allowing the outer and inner rings to be separated. Simultaneously, the fit between the protrusion and the round groove further enhances structural stability without affecting its detachable nature.

[0025] 2. In this utility model, the disassembly of the inner ring is extremely simple. Simply turn out the handle inside the storage slot, grasp the handle and pull upwards, and the inner ring can easily detach from the main body, simplifying the disassembly process, greatly improving operational efficiency, and bringing convenience to the user.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figures 1-4 One embodiment of this utility model is a detachable sealing ring structure, including an outer ring 1 and an inner ring 15. A fixing component is installed inside the outer ring 1, and a disassembly component is installed on the top of the inner ring 15.

[0036] The fixing assembly includes a first reinforcing steel 5, which is made of high-strength alloy steel and is arc-shaped, fitting tightly to the inner wall of the outer ring 1. The first reinforcing steel 5 is installed inside the outer ring 1. A second reinforcing steel 8 is rotatably connected to the first reinforcing steel 5 via a rotating shaft 9. The rotating shaft 9 is made of stainless steel, with its two ends embedded in the first and second reinforcing steel 8 respectively, forming a stable rotating connection structure. This allows the second reinforcing steel 8 to rotate flexibly around the rotating shaft 9. A round rod 6 is fixedly connected to the top of both the first and second reinforcing steel 5. The round rod 6 is vertically welded to the top of the first and second reinforcing steel 8 and is also made of stainless steel, providing high strength. The strength and corrosion resistance are good. A spring 7 is fixedly connected between the two round rods 6. The spring 7 is a high elasticity spring. Its two ends are fixed to the two round rods 6 by welding. Only by pulling the round rods 6 can the reinforcing steel 1 5 and the reinforcing steel 2 8 be loosened, so that the inner ring 15 can be taken out. Under normal circumstances, the two fit together. One end of the reinforcing steel 2 8 is provided with a round groove 10. The round groove 10 is a hemispherical groove with a diameter that matches the protrusion 11 and a moderate depth. It can ensure that the protrusion 11 can be inserted smoothly and provide sufficient clamping force. One end of the reinforcing steel 1 5 is fixedly connected to the protrusion 11. The protrusion 11 and the round groove 10 are interlocked.

[0037] The top of the outer ring 1 is equipped with an upper protective membrane 12, which is located above the reinforcing steel 2 8 and the reinforcing steel 1 5. The upper protective membrane 12 is made of transparent high-strength plastic material, which has good wear resistance and anti-aging properties, and can effectively protect the internal reinforcing steel 1 5 and the reinforcing steel 2 8 from external dust, moisture and other impurities. The upper protective membrane 12 has a sliding groove 14 inside, and the round rod 6 is slidably connected inside the sliding groove 14. The sliding groove 14 is a long strip groove that matches the round rod 6, and its length is slightly greater than the movement distance of the round rod 6 under the action of the spring 7. The outer side of the inner ring 15 has a groove 4, and the reinforcing steel 2 8 and the reinforcing steel 1 5 are both installed inside the groove 4. The shape and size of the groove 4 are adapted to the reinforcing steel 1 5 and the reinforcing steel 2 8. The installation of the reinforcing steel 1 5 and the reinforcing steel 2 8 inside the groove 4 makes the reinforcing steel 1 5 and the reinforcing steel 2 8 fit tightly with the inner ring 15, providing structural reinforcement without affecting the overall sealing performance and appearance of the sealing ring.

[0038] Reference Figure 1 , Figure 2 and Figure 6The disassembly assembly includes a storage slot 18, which is located at the top of the inner ring 15. The storage slot 18 is an arc-shaped groove that fits the handle 16. The depth is moderate, which ensures that the handle 16 can be stored in it without affecting the overall structure, and also makes it easy to rotate out when needed. The handle 16 is rotatably connected inside the storage slot 18. The handle 16 is made of plastic and has a non-slip texture on the surface. Both ends of the handle 16 are fixedly connected to rotating rods 17. Both rotating rods 17 are rotatably connected inside the storage slot 18. Circular holes that fit the rotating rods 17 are opened on both sides of the storage slot 18. The rotating rods 17 are inserted into the holes to allow the handle 16 to rotate flexibly inside the storage slot 18.

[0039] Reference Figure 1 , Figure 2 and Figure 5 The bottom of the outer ring 1 is fitted with a lower protective membrane 13, which is circular in shape and made of the same high-strength plastic as the upper protective membrane 12. It is tightly bonded to the bottom of the outer ring 1 through a hot-pressing process, further enhancing the sealing and protective properties of the sealing ring structure and preventing external impurities from entering the sealing ring from the bottom. Both sides of the outer ring 1 are provided with guide grooves 2, which are evenly distributed in a ring shape on the top of the outer ring 1. They can quickly and effectively guide away water, oil, and other liquids on the surface of the sealing ring, preventing liquid from accumulating on the surface of the sealing ring and affecting the sealing performance. The outer side of the outer ring 1 is provided with an installation groove 3, which is an annular groove used to cooperate with the external structure when installing the sealing ring, so that the sealing ring can be stably installed in the designated position.

[0040] Working principle: First, the reinforcing steel 8 provides reinforcement for the outer ring 1 and the inner ring 15, making the sealing ring structure more stable. When disassembling, simply pull the round rod 6 to both sides to stretch the spring 7. The spring 7 generates a restoring force, and the reinforcing steel 5 and the reinforcing steel 8 can be loosened. At this time, the outer ring 1 and the inner ring 15 can be removed. In addition, the protrusion 11 and the round groove 10 make the sealing ring structure more stable, and on this basis, it also has a detachable function.

[0041] Secondly, the disassembly of the inner ring 15 is extremely simple and convenient. First, simply turn the handle 16 slowly from its original position, disengaging it from the storage slot 18. Then, grip the handle 16 firmly and pull upwards with slight force; the inner ring 15 will easily detach from the main structure. This design not only greatly simplifies the disassembly process but also significantly improves operational efficiency, enabling rapid disassembly and providing users with immense convenience.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
