Description

Technical Field

[0001] This utility model relates to the field of sealing silicone ring technology, specifically a waterproof sealing silicone ring. Background Technology

[0002] In the field of silicone sealing ring technology, silicone rings are widely used in many industries such as home appliances, automobiles, electronics, and machinery as key components for waterproofing, dustproofing, and preventing media leakage between equipment parts. However, existing silicone sealing rings still have many technical pain points that need to be solved in actual use, making it difficult to meet the high sealing requirements under complex working conditions. Firstly, traditional silicone sealing rings mostly employ a single structural design, relying solely on the elasticity of the silicone itself to adhere to the component surface. This results in a single sealing layer. When temperature fluctuations occur during equipment operation, the silicone material is prone to thermal expansion and contraction, leading to increased gaps between the sealing surfaces. Furthermore, under vibration, relative displacement between components can disrupt the tight seal, increasing the risk of leakage and severely impacting the normal operation and lifespan of the equipment. Existing silicone rings lack an effective pre-positioning structure for assembly, making misalignment during installation easy. Misalignment between the silicone ring and the component not only directly leads to seal failure but may also cause deformation or damage to the silicone ring due to forced assembly, increasing assembly difficulty and rework rate, and reducing production efficiency. Therefore, a waterproof silicone sealing ring is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a waterproof sealing silicone ring, which solves the problem of poor sealing performance of the silicone ring.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a waterproof sealing silicone ring, comprising a ring base, wherein a conical block is fixedly installed on the upper surface of the ring base; The ring base is provided with a sealing mechanism, which includes a connector, a pleated groove and a conical groove. The connector is fixedly installed on the upper surface of the ring base, and the pleated groove is opened on the outer surface of the connector.

[0005] Preferably, the tapered groove is formed on the lower surface of the connector.

[0006] Preferably, the sealing mechanism further includes a spring groove and an annular inner hoop spring, the spring groove being formed on the outer surface of the connector, and the annular inner hoop spring being fixedly installed in the inner wall of the spring groove.

[0007] Preferably, the sealing mechanism further includes a covering ring and an anti-slip pad, with the covering ring fixedly installed on the inner surface of the connector; The anti-slip pad is fixedly installed on the inner surface of the covering ring, and the surface of the anti-slip pad is set with raised particles.

[0008] Preferably, the sealing mechanism further includes a ring top seat, which is fixedly installed on the upper surface of the connecting body.

[0009] Preferably, the surface of the anti-slip mat is striped.

[0010] Compared with the prior art, the present invention provides a waterproof sealing silicone ring, which has the following beneficial effects: 1. This waterproof sealing silicone ring significantly improves waterproof performance through a multi-layer sealing design. The conical block achieves pre-positioning during assembly, avoiding sealing failure caused by misalignment. The pleated groove expands under pressure, allowing the connector to fit tightly against the inner wall of the component to form a radial seal. The annular inner hoop spring provides continuous rebound force when the connector deforms, compensating for gaps caused by temperature changes or vibrations, and ensuring stable sealing pressure. The combination of multiple structures allows the silicone ring to maintain excellent sealing performance under different working conditions, effectively eliminating the risk of leakage.

[0011] 2. The waterproof sealing silicone ring features a conical block that simplifies the assembly process and reduces operational difficulty. The top seat of the ring and the base of the ring form an upper and lower support, improving the overall structural strength. The anti-slip pad covering the inside of the ring increases friction and prevents the silicone ring from sliding axially due to vibration. This design improves assembly efficiency, reduces positional displacement during long-term use, and extends the service life of the seal. Attached Figure Description

[0014] 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.

[0015] Please see Figure 1-4 This utility model provides a new technical solution: a waterproof sealing silicone ring, including a ring base 1: as the basic support component of the entire silicone ring, it undertakes the core role of installation positioning and structural bearing. It provides a stable installation platform for other components, ensures the initial fit between the silicone ring and the equipment installation surface, and prevents overall deformation through its own structural strength. It is the primary foundation for ensuring the stability of the sealing system.

[0016] Conical block 2: Fixed to the upper surface of the ring base 1, it mainly plays the role of deformation guidance and structural reinforcement. When the silicone ring is compressed, the conical structure can directionally disperse the pressure to prevent the ring base 1 from shifting due to uneven force. At the same time, it enhances the tightness of the connection between the base and the upper connector 3, reduces the risk of delamination and detachment after long-term use, and improves the overall structural durability.

[0017] Connector 3: It is the core connection hub of the sealing mechanism. It connects to the top seat 10 of the ring body above and the base 1 of the ring body below. It integrates a variety of sealing components. It not only plays a physical connection role between components, but also provides a carrier for the opening of structures such as the pleated groove 4 and the spring groove 6. Through its own structural design, it integrates various sealing elements to form an overall sealing framework.

[0018] Pleated groove 4: It is formed on the outer surface of the connector 3 and has the function of elastic deformation compensation. When there is slight vibration or installation error in the equipment, the pleated structure can absorb the displacement through expansion and contraction deformation, and always keep the connector 3 in close contact with the sealing surface; at the same time, it increases the contact area with the sealing medium, improves the radial sealing effect, and enhances the waterproof performance.

[0019] Conical groove 5: Located on the lower surface of connector 3, it mainly realizes pressure guidance and sealing enhancement. When under pressure, the conical space can guide the pressure to the outside and inside of connector 3, causing the pleated groove 4 and the covering ring 8 to fit more tightly against the sealing surface; at the same time, it forms a local negative pressure area, further blocking moisture penetration and helping to improve the overall sealing level.

[0020] Spring groove 6: As the mounting carrier for the annular inner hoop spring 7, it is opened on the outer surface of the connector 3. Its structural dimensions are precisely matched with the spring to ensure that the annular inner hoop spring 7 is stably fixed and does not shift. At the same time, it reserves reasonable space for the elastic deformation of the spring, so that the spring can continuously apply a uniform clamping force to the connector 3 and ensure the durability of the seal.

[0021] Annular inner clamping spring 7: Installed on the inner wall of spring groove 6, its core function is to provide continuous radial clamping force. It utilizes the elastic characteristics of the spring to always generate an inward clamping force on the connecting body 3, so that the connecting body 3 and the covering ring 8 are tightly attached to the surface of the sealed part, to compensate for the elastic fatigue of the silicone material after long-term use, and to avoid water leakage caused by the decay of sealing force.

[0022] Encasing ring 8: Fixed to the inner surface of connector 3, it is an inner layer structure that directly contacts the sealed part. It is made of soft and aging-resistant silicone material, which can closely fit the surface contour of the sealed part and fill tiny gaps; at the same time, it protects the internal structure of connector 3, avoids damage from burrs or impurities on the surface of the sealed part, and extends the service life of the sealing mechanism.

[0023] Anti-slip pad 9: Fixed on the inner surface of the covering ring 8, the surface is set with convex particles. Its main function is to increase the friction between the covering ring 8 and the sealed part, and prevent the silicone ring from axial displacement during equipment operation or vibration. The convex structure can also further fill the micro-unevenness of the contact surface, enhance the tightness of the seal, and provide double protection for the stability of the seal.

[0024] Ring top seat 10: Fixed on the upper surface of the connector 3, serving as the top pressure-bearing component of the silicone ring. It evenly transmits external pressure to the connector 3 and the sealing components below, ensuring balanced pressure distribution. At the same time, it seals the top structure of the connector 3, preventing foreign objects from entering the sealing mechanism, protecting core components such as the spring and the cover ring, and maintaining the integrity of the sealing system.

[0025] When the waterproof sealing silicone ring is mated with the component to be sealed, the ring base 1 first adheres to the mounting surface for initial positioning. At this time, the conical block 2 on the upper surface of the ring base 1 acts as a guide, and its conical structure guides the mating component to be accurately fitted into the inner side of the connector 3, avoiding the risk of sealing failure caused by assembly misalignment. At the same time, the conical block 2 itself undergoes slight elastic deformation under the pressure of the mating component, forming the first layer of preliminary seal. As the mating component continues to be pressed down, the ring top seat 10 first receives axial pressure and transmits the pressure to the connector 3 below. The pleated groove 4 on the outer surface of the connector 3 undergoes pleating and expansion deformation under the action of axial pressure. During the deformation process, it expands outward, making the outer surface of the connector 3 tightly fit with the inner wall of the mating component, forming the second layer of radial seal. At the same time, the conical groove 5 on the lower surface of the connector 3... Due to pressure contraction, the sealing performance of the connection between the connector 3 and the base 1 is further enhanced, preventing water from seeping in from the gap between the base and the connector. The annular inner hoop spring 7 in the spring groove 6 on the outer surface of the connector 3 is elastically stretched synchronously when the connector 3 expands. The rebound force generated by the spring acts on the connector 3, so that the connector 3 always maintains the pressure on the inner wall of the mating part. Even when the temperature changes or vibrations cause slight displacement of the parts, the elastic compensation effect of the annular inner hoop spring 7 can maintain the pressure stability of the sealing surface and avoid the appearance of sealing gaps. The covering ring 8 on the inner surface of the connector 3 is tightly attached to the outer side of the mating part as the connector 3 deforms. The anti-slip pad 9 on the inner side of the covering ring 8 increases the friction force to prevent the silicone ring from sliding axially due to vibration or pressure changes during long-term use, ensuring the positional stability of the overall sealing structure. Example 1: Striped anti-slip pads are suitable for scenarios with high axial pressure and high surface precision of the sealed components. like Figure 4 As shown: The anti-slip pad 9 is also fixed to the inner surface of the covering ring 8. The surface adopts a ring stripe design. The stripes are distributed along the circumference of the anti-slip pad 9 and are a continuous convex stripe structure. The stripes and the main body of the anti-slip pad 9 are integrally molded. The material is silicone material with better flexibility. After assembly, the annular stripes form a ring-shaped line contact seal with the surface of the sealed component. When the silicone ring is subjected to axial thrust or equipment vibration, the stripe structure generates a lateral reaction force through its own compression deformation, preventing the silicone ring from sliding axially. Simultaneously, the annular stripes can form multiple independent sealing bands with the surface of the sealed component, not only providing anti-slip functionality but also enhancing the inner layer's sealing effect and reducing the risk of moisture seeping in from the contact surface between the anti-slip pad and the sealed component. Furthermore, the circumferential distribution of the stripes makes it easier for the anti-slip pad to conform to sealed components of different diameters during assembly, resulting in greater adaptability.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
