[0002] An anti-static and anti-leakage sealing ring is a sealing element specifically designed to prevent the accumulation of static electricity and liquid leakage. They are particularly important in industries such as electronics, chemical engineering, petroleum, and natural gas, because the equipment and components in these industries are sensitive to static electricity, which can cause sparks, explosions, or data damage.

[0003] Although traditional sealing rings can achieve a sealing effect, in some occasions where vibration and rotation occur, it is difficult to achieve an effective anti-leakage effect. It is difficult for the sealing ring to realize this basic function, which will lead to a decline in the performance of the equipment. Because the leaked medium will affect the normal operation of the equipment. In a hydraulic system or a pneumatic system, the leakage of the sealing ring will cause energy loss, because compressed air or liquid will escape from the system, which means that the system needs more energy to maintain operation. Therefore, an anti-static and anti-leakage sealing ring is proposed to solve the above problems. Summary of the Utility Model

[0004] To make up for the above deficiencies, the utility model provides an anti-static and anti-leakage sealing ring, aiming to improve the problem that traditional sealing rings in the existing technology are difficult to achieve an effective anti-leakage effect in some occasions where vibration and rotation occur.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An anti-static and anti-leakage sealing ring, comprising two connecting pipes. An annular groove is formed in the inner wall of the connecting pipe. A sealing main body is rotatably connected to the inner wall of the connecting pipe. An anti-leakage component for sealing is fixedly connected to the outer wall of the sealing main body. A filling component for anti-static is fixedly connected to the inner wall of the sealing main body;

[0007] As a further description of the above technical scheme:

[0008] The anti-leakage component includes a sealing ring. The outer wall of the sealing ring is fixedly connected to the outer wall of the sealing main body. A conical soft sheet is fixedly connected to the outer wall of the sealing main body;

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

[0010] Clamping blocks are respectively fixedly connected to the adjacent right sides of the two sealing main bodies. A soft body ring is slidably connected to the inner wall of the clamping block;

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

[0012] The filling component includes a conductive rubber layer, the outer wall of the conductive rubber layer is fixedly connected to the inner wall of the sealing body, and a fluororubber layer is fixedly connected to the inner wall of the sealing ring;

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

[0014] A silica gel layer is fixedly connected to the inner wall of the conical soft sheet, and a polyurethane layer is fixedly connected to the inner wall of the soft ring;

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

[0016] A sealing ring is rotatably connected to the inner wall of the connecting pipe, and the outer wall of the sealing ring is rotatably connected to the inner wall of the annular groove;

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

[0021] The utility model has the following beneficial effects:

[0022] 1. In the utility model, by engaging two sealing bodies, the soft ring is clamped therein, and the sealing ring is clamped in the annular groove. Therefore, the anti-leakage effect is achieved.

In a hydraulic system or a pneumatic system, the anti-leakage of the sealing ring will reduce energy loss, ensure that compressed air or liquid is difficult to overflow from the system, and reduce the need for the system to consume more energy to maintain operation.

[0023] 2. In the utility model, a good conductive network can be formed through the conductive rubber layer, effectively shielding external electromagnetic interference and radio frequency interference, which is crucial for improving the electromagnetic compatibility of electronic devices.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figures 1 to 3 The utility model provides an embodiment: an anti-static and leak-proof sealing ring, including two connecting tubes 1, the inner wall of the connecting tube 1 is rotatably connected with a sealing ring 4, and the outer wall of the sealing ring 4 is rotatably connected to the inner wall of the annular groove 2. The function of the annular groove 2 is to accommodate key sealing components, ensure its rotation and positioning freedom, and thus achieve more effective sealing and anti-static functions. An annular groove 2 is provided on the inner wall of the connecting tube 1, and a sealing body 3 is rotatably connected to the inner wall of the connecting tube 1, and a sealing body 3 is rotatably connected to the inner wall of the annular groove 2, which is located in the connecting tube 1. The unique design thereof is that it is not only rotatably connected with the inner wall of the connecting tube 1, but also rotatably connected with the inner wall of the annular groove 2. This double-layer connection ensures that the sealing body 3 can still flexibly adjust its posture when subjected to external stress, thereby improving the sealing efficiency while reducing friction loss.

[0032] The outer wall of the sealing body 3 is in contact with the outer wall of the soft ring 7. The outer wall of the sealing body 3 is fixedly connected with a leakproof component for sealing, and the inner wall of the sealing body 3 is fixedly connected with a filling component for anti-static. The leakproof component includes a sealing ring 4, the outer wall of the sealing ring 4 is fixedly connected to the outer wall of the sealing body 3, and the outer wall of the sealing body 3 is fixedly connected with a conical soft film 5. The sealing ring 4 is closely attached to the outer edge of the sealing body 3, forming the first line of defense to prevent fluid leakage; and the conical soft film 5 further enhances the effect of this barrier, and its design cleverly uses its own deformation characteristics to adapt to the slight differences of different sealing surfaces to ensure that there is no gap.

[0033] The inner wall of the connecting tube 1 is slidably connected with a conical soft film 5, and the outer wall of the conical soft film 5 is slidably connected to the inner wall of the annular groove 2. The two sealing bodies 3 are fixedly connected to the right sides thereof, and cooperate with each other to form a dynamic adjustment mechanism: when the external conditions change, the soft ring 7 can slide between the blocks 6, automatically adjust the position to adapt to the changes of different sizes or shapes, and maintain a good sealing state at the same time. The inner wall of the block 6 is slidably connected with the soft ring 7.

[0034] Reference Figure 2 , Figure 4 , the filling component includes a conductive rubber layer 8, which acts as the core anti-static functional unit. Made of carefully selected materials with excellent conductive properties, the conductive rubber layer 8 can quickly guide and disperse any accumulated static charge, significantly reducing the safety hazards caused by static electricity. This design is particularly suitable for those occasions that are highly sensitive to static electricity, such as semiconductor manufacturing, precision instrument packaging and other industries, to ensure electrical safety during operation. The outer wall of the conductive rubber layer 8 is fixedly connected to the inner wall of the sealing body 3, and the inner wall of the sealing ring 4 is fixedly connected to the fluororubber layer 9. Another layer of protection barrier is added to the overall sealing ring. In view of the excellent chemical stability and temperature resistance of fluororubber materials, even in harsh environments under high temperature, high pressure or strong chemical corrosion conditions, the fluororubber layer 9 can still maintain excellent sealing performance, greatly improving the reliability and life of the sealing ring.

[0035] The inner wall of the conical soft film 5 is fixedly connected with a silicone layer 10, which is not only a reinforcement and supplement to the original material properties, but also to optimize its thixotropy and resilience. The presence of the silicone layer 10 makes the conical soft film 5 more flexible and durable, and can better adapt to complex curved surfaces while maintaining a high level of sealing. Especially in the repeated opening and closing operations, the addition of the silicone layer 10 ensures that the sealing ring is always in the best working condition, avoiding the common problems of hardening or cracking. The inner wall of the soft ring 7 is fixedly connected with a polyurethane layer 11. The high elasticity and strength advantages of the polyurethane material are fully utilized. The polyurethane layer 11 can not only withstand large mechanical loads, but also remain stable under various temperature conditions, ensuring that the soft ring 7 can still maintain the original sealing effect when encountering unexpected impacts or temperature changes.

[0036] Working principle: At the beginning, the user needs to manually or with the aid of tools rotate the sealing bodies 3 on both sides. This action drives the components under the sealing bodies 3 to move accordingly. As the sealing bodies 3 undergo relative displacement until they are completely aligned and engaged with each other, this process is as smooth and natural as the meshing of precisely matched gears, which not only tests the fineness of the design but also demonstrates the rigor of the assembly. Once the sealing bodies 3 are aligned, the soft ring 7 smoothly slides into place along the preset trajectory and precisely fits into the gap between the clamping blocks 6. At this time, the soft ring 7 is squeezed, and its elastic and deformable material properties enable it to closely adhere to the periphery of the clamping blocks 6, forming a seamless closed barrier. The key to this step lies in the dense connection formed between the soft ring 7 and the clamping blocks 6, which not only strengthens the stability of the entire sealing ring but also effectively resists the intrusion of external factors. Meanwhile, the sealing ring 4 plays an important supporting role in this series of actions. It is precisely clamped within the annular groove 2 of the connecting pipe 1. Due to the combination of rigidity and elasticity of the sealing ring 4 and its tight fit with the groove wall, it can withstand the pressures from both inside and outside and distribute the forces evenly, ensuring the balance and integrity of the entire sealing ring structure. Such a design makes the sealing ring 4 the core framework of the sealing ring, endowing it with sufficient strength to cope with complex usage environments. Moreover, the conical soft sheet 5 exerts its unique gripping force at this time. The combined effect of its conical design and material properties generates a strong adsorption similar to the suction cup effect, firmly grasping the surrounding structural components. This characteristic is particularly crucial when the sealing ring is subjected to external pressure or vibration. It can effectively prevent the sealing ring from unnecessary movement or deflection, ensuring that even under harsh conditions, the sealing ring can maintain its position and continue to perform its due functions.

[0037] A good conductive network can be formed through the conductive rubber layer 8, effectively shielding external electromagnetic interference and radio frequency interference, which is crucial for improving the electromagnetic compatibility of electronic devices. Good corrosion resistance to most chemicals, including oils, fuels, solvents, acids, and alkalis, is achieved through the fluororubber layer 9. A very high resistivity is achieved through the silica gel layer 10, and its resistance can remain stable within a wide temperature range and frequency range, making it suitable for manufacturing insulating components and materials. Silica gel has excellent elasticity and softness, can withstand deformation within a large range without cracking or damage, and provides a gripping force to avoid slipping. A closed-cell structure is achieved through the polyurethane layer 11, with extremely low water absorption rate, excellent waterproof and moisture-proof properties. Polyurethane has relatively high compressive strength and tensile strength, can withstand large loads, and is wear-resistant.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
