Description

Technical Field

[0001] This utility model relates to the field of mechanical seal technology, specifically a silicone ring with anti-leakage and anti-seepage functions. Background Technology

[0002] As the most widely used sealing component in mechanical devices, silicone gaskets directly determine the safety and reliability of equipment operation due to their leak-proof and seepage-proof performance. However, existing silicone gaskets still face many technical bottlenecks under complex working conditions: traditional silicone gaskets are mostly of a single homogeneous structure, which is prone to deformation and relaxation when affected by pressure fluctuations or temperature changes, leading to the appearance of sealing gaps. This leakage problem is particularly prominent in high-pressure or high-frequency vibration equipment.

[0003] To improve stability, some products incorporate rigid frames, but this can easily compromise the flexibility of the silicone, creating a contradiction of "excessive rigidity and insufficient fit." Meanwhile, existing silicone ring fixing structures are mostly custom-designed, installed via bolts or adhesives. This not only results in low installation efficiency but also fails to adapt to the sealing groove structures of different types of mechanical devices, requiring customized solutions and increasing usage costs and inventory pressure.

[0004] Furthermore, when the sealing surface of the equipment has microscopic scratches or rough defects, traditional silicone rings are difficult to actively fill the gaps, and the sealing grease is easily consumed and cannot be replenished; the fixing components are prone to loosening under vibration, further increasing the risk of leakage. Therefore, a silicone ring with leak-proof and seepage-proof functions has been invented to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a silicone ring with anti-leakage and anti-seepage functions to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a silicone ring with anti-leakage and anti-seepage function, comprising a silicone ring, wherein a bonding component is correspondingly connected inside the silicone ring, the bonding component comprising a hollow annular metal elastic skeleton, the outer surface of the elastic skeleton being tightly bonded to the core of the silicone ring, which neither affects the flexibility of the silicone ring itself, but also provides bidirectional elastic compensation capability. The outer surface of the silicone ring is secured with a fixing component via anti-slip serrations. This fixing component is a detachable modular metal retaining ring, with an integrally formed arc-shaped contact portion on its inner side that matches the outer surface of the silicone ring. This fixing component allows for quick positioning and fixation of the silicone ring and sealing groove through rotation. Furthermore, by replacing the interface adapter, it can be matched with the sealing structures of different types of mechanical devices, significantly enhancing versatility and ease of installation.

[0007] As a preferred technical solution of this utility model, the bonding component includes an elastic skeleton, the upper and lower ends of which are connected to the inside of the silicone ring, and several hollow blocks are correspondingly arranged inside the elastic skeleton.

[0008] As a preferred embodiment of this utility model, each of the hollowed-out blocks is connected to a corresponding fitting block at its hollowed-out portion, and a spring is connected to the groove on the outer surface of the elastic skeleton.

[0009] As a preferred embodiment of the present invention, the fixing component includes a first connecting rod, both ends of which are movably connected to a rotating shaft.

[0010] As a preferred embodiment of this utility model, the centers of the two rotating shafts are movably connected to one end of the second connecting rod and the third connecting rod, and the protruding part of the other end of the third connecting rod is movably connected to a buckle.

[0011] As a preferred embodiment of this utility model, the other end of the second connecting rod is movably connected to one side of the locking block, and the other side of the locking block is connected to the central protrusion of the buckle.

[0012] Compared with the prior art, the beneficial effects of this utility model are: A silicone ring with leak-proof and seepage-proof functions is provided by tightly binding the elastic skeleton to the silicone ring core, which provides bidirectional elastic compensation without compromising the flexibility of silicone, thus solving the problem of sealing failure caused by pressure fluctuations and temperature changes.

[0013] A silicone ring with leak-proof and seepage-proof functions uses a ring-shaped elastic skeleton to ensure that the skeleton and silicone ring are subjected to uniform force, avoiding silicone deformation caused by local stress concentration. The distribution design of several hollow blocks reduces the weight of the skeleton while reserving sufficient deformation space for the silicone ring, ensuring the sealing and adhesion ability of the silicone itself, and achieving the synergistic effect of "rigid support-flexible sealing".

[0014] A silicone ring with anti-leakage and anti-seepage functions further optimizes the force transmission performance of the skeleton by filling the gaps of the hollow block with the bonding block, so that the elastic compensation force is evenly applied to the silicone ring; while the spring on the outer surface of the elastic skeleton forms a secondary elastic buffer. When the device is subjected to vibration and impact, the spring can absorb the instantaneous impact force, avoid damage to the skeleton and silicone ring due to rigid impact, and extend the service life of the sealing component.

[0015] A silicone ring with anti-leakage and anti-seepage functions uses a first connecting rod as a basic support component and cooperates with the rotating shafts at both ends to realize multi-angle rotation of the second and third connecting rods, so that the fixing component can be adapted to sealing grooves of different diameters, improving installation flexibility and solving the problem of "fixed size and poor adaptability" of traditional snap rings.

[0016] A silicone ring with leak-proof and seepage-proof function uses a linkage structure between the second and third connecting rods and a rotating shaft to adjust the clamping range, adapting to silicone rings and sealing grooves of different thicknesses; at the same time, the interlocking of the buckle and the locking block forms a double lock, ensuring that the fixing component is not easy to loosen after installation.

Detailed Implementation

[0019] 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.

[0020] Example: Please refer to Figure 1 A silicone ring with anti-leakage and anti-seepage function includes a silicone ring 10. The silicone ring 10 is connected to an adhesive component 20. The adhesive component 20 includes a hollow ring-shaped metal elastic skeleton 201. The outer surface of the elastic skeleton 201 is tightly bonded to the core of the silicone ring 10, which does not affect the flexibility of the silicone ring 10 itself, and can provide bidirectional elastic compensation capability. The outer surface of the silicone ring 10 is secured with a fixing component 30 via anti-slip serrations. The fixing component 30 is a detachable modular metal retaining ring, with an integrally formed arc-shaped contact portion on its inner side that matches the outer surface of the silicone ring 10. This fixing component 30 allows for quick positioning and fixation of the silicone ring 10 to the sealing groove via rotation. Furthermore, by replacing the interface adapter, it can be matched with the sealing structures of different types of mechanical devices, significantly enhancing versatility and ease of installation. Example 2: Based on Example 1, as follows Figure 2-4As shown, the bonding component 20 includes an elastic skeleton 201. The upper and lower ends of the elastic skeleton 201 are connected to the interior of the silicone ring 10. Several hollow blocks 202 are provided inside the elastic skeleton 201. The annular structure of the elastic skeleton 201 ensures uniform force distribution between the skeleton and the silicone ring 10, avoiding silicone deformation caused by localized stress concentration. The distribution of the hollow blocks 202 reduces the weight of the skeleton while providing sufficient deformation space for the silicone ring 10, ensuring the sealing and bonding ability of the silicone itself, achieving a synergistic effect of "rigid support - flexible sealing." Furthermore, the interior of the elastic skeleton 201 is connected to the outer surface of the hollow blocks 202.

[0021] Each of the hollowed-out blocks 202 has a fitting block 203 at its hollowed-out portion, and each hollowed-out portion of the hollowed-out blocks 202 is connected to the outer surface of the fitting block 203. A spring 204 is installed in the groove on the outer surface of the elastic frame 201. The fitting blocks 203 fill the gaps in the hollowed-out blocks 202, further optimizing the force transmission performance of the frame and ensuring that the elastic compensation force is evenly applied to the silicone ring 10. The spring 204 on the outer surface of the elastic frame 201 forms a secondary elastic buffer. When the device is subjected to vibration and impact, the spring 204 can absorb the instantaneous impact force, preventing damage to the frame and silicone ring 10 due to rigid impact and extending the service life of the sealing assembly. Furthermore, the groove on the outer surface of the elastic frame 201 is connected to the inner surface of the spring 204.

[0022] The fixing component 30 includes a first connecting rod 301, with a rotating shaft 302 at both ends of the first connecting rod 301, and both ends of the first connecting rod 301 are movably connected to both ends of the rotating shaft 302.

[0023] Each of the two rotating shafts 302 has a second connecting rod 303 and a third connecting rod 304 at its center, and the centers of the two rotating shafts 302 are movably connected to one end of the second connecting rod 303 and the third connecting rod 304. A buckle 305 is provided on the protruding part of the other end of the third connecting rod 304. Using the first connecting rod 301 as a basic support component, and in conjunction with the two rotating shafts 302, the second connecting rod 303 and the third connecting rod 304 can rotate at multiple angles. This allows the fixing assembly 30 to adapt to sealing grooves of different diameters, improving installation flexibility and solving the problem of "fixed size and poor adaptability" of traditional retaining rings. Furthermore, the protruding part of the other end of the third connecting rod 304 is movably connected to the inner groove of the buckle 305.

[0024] The other end of the second connecting rod 303 is provided with a locking block 306, and the other end of the second connecting rod 303 is movably connected to one side of the locking block 306, and the other side of the locking block 306 is connected to the central protrusion of the buckle 305. Through the linkage structure of the second connecting rod 303 and the third connecting rod 304, the clamping amplitude is adjusted by the rotating shaft 302 to adapt to silicone rings 10 and sealing grooves of different thicknesses; at the same time, the concave and convex fit between the buckle 305 and the locking block 306 forms a double lock, ensuring that the fixing component 30 is not easy to loosen after installation, and can maintain stable fixation even under high-frequency vibration conditions of the equipment, avoiding sealing leakage indirectly caused by fixation failure.

[0025] The working principle of this utility model is as follows: First, the silicone ring 10 serves as the core sealing carrier. Its core is tightly bonded to the outer surface of the elastic skeleton 201 in the bonding component 20. The ring structure of the elastic skeleton 201 ensures that the force on itself and the silicone ring 10 is uniform, avoiding local stress concentration that could cause the silicone ring 10 to deform. At the same time, the several hollow blocks 202 inside the elastic skeleton 201 reduce its own weight while reserving sufficient deformation space for the silicone ring 10, allowing the silicone ring 10 to rely on its own flexibility to tightly bond to the sealing surface, achieving the basic synergy of "rigid support - flexible sealing". To prevent gaps between the silicone ring 10 and the sealing surface, the fitting block 203 at the hollowed-out part of the hollowed-out block 202 further optimizes the force transmission performance, so that the compensating force of the elastic skeleton 201 is evenly applied to all parts of the silicone ring 10, ensuring that the sealing surface is subjected to consistent force. The spring 204 in the groove on the outer surface of the elastic skeleton 201 forms a secondary elastic buffer. When the device is subjected to vibration and impact, the spring 204 can absorb the instantaneous impact force, avoid damage to the elastic skeleton 201 and silicone ring 10 due to rigid impact, and extend the service life of the overall sealing assembly. While the silicone ring 10 achieves dynamic sealing, its outer surface is secured by a fixing component 30 with anti-slip toothed engagement, which provides stable installation. The first connecting rod 301 in the fixing component 30 serves as a basic support component, and together with the rotating shafts 302 at both ends, it enables the second connecting rod 303 and the third connecting rod 304 to rotate at multiple angles. The operator can adjust the angle between the second connecting rod 303 and the third connecting rod 304 through the rotating shaft 302, thereby adjusting the clamping range of the fixing component 30 to adapt to sealing grooves with different diameters and thicknesses and the silicone ring 10, thus solving the problem of poor compatibility of traditional retaining rings. After the fixing component 30 is adjusted to the appropriate size, it is fitted onto the outer surface of the silicone ring 10 by rotating and snapping. At this time, the arc-shaped contact part integrally formed on the inner side of the retaining ring is tightly fitted to the outer surface of the silicone ring 10, which enhances the snapping stability. Subsequently, the buckle 305 of the protruding part of the third connecting rod 304 and the locking block 306 of the other end of the second connecting rod 303 form a double lock through the concave-convex cooperation, ensuring that the fixing component 30 is not easy to loosen after installation. Even under the high-frequency vibration condition of the equipment, it can still maintain the stable fixation of the silicone ring 10, and prevent the silicone ring 10 from deviating from the sealing position due to loose installation. The silicone ring 10 is internally fitted with a corresponding bonding component 20, which is a hollow ring-shaped memory metal elastic skeleton. This skeleton is tightly integrated with the core of the silicone ring 10, which does not affect the flexibility of the silicone ring 10 itself, and can provide bidirectional elastic compensation capability. When the internal pressure of the device increases, it generates radial expansion force to enhance the sealing fit. When the pressure decreases or the device shrinks due to cold, it prevents the silicone ring 10 from loosening through rebound force. The fixing component 30, which is connected by anti-slip toothed snap-fit ​​on its outer surface, is a detachable modular metal snap ring. The inner side of the snap ring has an integrally formed arc-shaped contact part that matches the outer surface of the silicone ring 10. The fixing component 30 can quickly position and fix the silicone ring 10 to the sealing groove by rotating and snapping, which improves the installation efficiency. At the same time, by changing the interface adapter, it can be matched with the sealing structure of different types of mechanical devices, which significantly enhances the versatility and installation convenience.
