Description

Technical Field

[0001] This invention relates to the field of sealing ring structures, and in particular to sealing ring structures for electronic devices. Background Technology

[0002] In daily use and various environments, electronic devices often rely on sealing rings to seal critical parts to prevent water, dust and other impurities from entering the interior, thus ensuring the normal operation and service life of the equipment. Therefore, sealing ring structures occupy an important position in the field of sealing and protection of electronic devices. Existing sealing ring structures for electronic devices have shortcomings in terms of fixing to the device mounting location. They lack an effective clamping mechanism, making them prone to loosening during use and resulting in unstable sealing positions. At the same time, their sealing structures are relatively simple, often only achieving a single-layer seal, making it difficult to form a multi-directional, multi-layer sealing effect. Their sealing performance is limited, and their ability to block water, dust, and other impurities is insufficient, making it difficult to guarantee the reliability and durability of the seal and failing to provide sufficient and effective protection for electronic devices. Summary of the Invention

[0003] In view of the shortcomings of the prior art, this application provides a sealing ring structure for sealing electronic devices to solve the above-mentioned technical problems that often can only achieve a single-layer seal, making it difficult to form a multi-directional and multi-layer sealing effect, with limited sealing performance and insufficient ability to block water, dust and other impurities, making it difficult to guarantee the reliability and durability of the seal, and failing to provide sufficient and effective protection for electronic devices.

[0004] To achieve the above objectives, this application provides the following technical solution: a sealing ring structure for sealing electronic devices, comprising a ring body structure, a groove, and a sealing element, wherein the groove is uniformly opened on the outside of the ring body structure, and the sealing element is disposed in the inner cavity of the ring body structure.

[0005] The outer side of the ring structure is uniformly provided with a clamping mechanism. The clamping mechanism includes a pusher, a folding member is rotatably connected to the outside of the pusher, a first rack is connected to the other end of the pusher, a gear is meshed with the upper end of the first rack, a second rack is meshed with the upper end of the gear, and a clamping member is connected to the outside of the second rack.

[0006] When the folding component is rotated under force, it can drive the pushing component to move. The movement of the pushing component will cause the first rack to move synchronously. The first rack drives the gear to rotate through meshing with the gear. The gear then drives the second rack to move in the opposite direction, causing the clamping component to move closer to the connection part of the electronic device, thereby achieving clamping and fixing between the sealing ring and the electronic device.

[0007] Effectively prevents the sealing ring from shifting or falling off during use; the outer side of the ring structure is provided with a sealing mechanism, which includes a first airbag, a second airbag and a third airbag. The first airbag is assembled at the upper end of the ring structure, and the second and third airbags are respectively embedded at the upper and lower ends of the inner cavity of the ring structure. The first airbag, the second airbag and the third airbag are connected by a hose. When air is inflated into the first airbag...

[0008] Gas can be rapidly injected into the second and third airbags through the hose, causing all three airbags to inflate simultaneously. The first airbag, after inflating, fits tightly against the upper surface of the electronic device, achieving a seal at the top of the ring structure. The second and third airbags, after inflating, fit against the electronic device components at the upper and lower ends of the ring structure's inner cavity, respectively, thus forming sealing barriers from multiple locations. This improves the overall sealing performance of the electronic device and effectively prevents dust, moisture, and other impurities from entering the device.

[0009] The inner cavity of the ring structure is uniformly provided with grooves. The upper and lower ends of the grooves are slidably connected to guide members through the track grooves. The two sets of guide members are respectively connected to the second rack and the first rack. The guide members can slide stably along the track grooves, providing precise guidance for the movement of the second rack and the first rack, avoiding the rack from deviating or getting stuck during the movement, and ensuring smoother and more stable transmission between the components of the clamping mechanism. The second rack has mounting seats on both sides, and elastic elements are connected to the outside of the mounting seats. The elastic elements are connected to the inner cavity of the groove. When the second rack moves under the drive of the gear, the mounting seats will pull or compress the elastic elements. The elastic restoring force generated by the elastic elements can buffer the mounting seats and the second rack, making the clamping force of the clamping parts more gentle and uniform. At the same time, after the external force disappears, it can drive the second rack, gear, first rack and other components to reset, which is convenient for the next use.

[0010] The bottom of the ring structure has a storage groove, and the inner cavity of the storage groove is fitted with a rubber pad. The inner cavity of the storage groove is adapted to the outside of the first airbag. When the first airbag is not inflated, it can be stored in the storage groove. The rubber pad can protect the first airbag and prevent it from being damaged by direct friction with the ring structure.

[0011] The adaptable structure of the storage slot can prevent the first airbag from shaking randomly when it is not in use; magnets are provided on the outside of the folding part and the inner cavity of the slot, and the magnets of the two sets of magnets attract each other. When the folding part is rotated into the slot, the two sets of magnets attract each other and can firmly fix the folding part in the slot, preventing the folding part from being accidentally unfolded or loosened when it is not in use, and ensuring the stability of the overall structure of the clamping mechanism.

[0012] Both sides of the gear are connected to seated bearings. The two sets of seated bearings are connected to the inner cavity of the groove by bolts. The seated bearings can stably support the gear in the groove, ensuring that the gear axis position remains fixed during rotation, avoiding the impact on the meshing accuracy with the first and second racks due to gear offset, thereby ensuring the transmission efficiency and reliability of the clamping mechanism.

[0013] The folding component consists of at least two metal rods connected by a hinge, with the rotation angle between adjacent metal rods ranging from 0° to 180°. This structure allows the folding component to be folded and unfolded flexibly. When the angle is 0°, it can be folded and stored, significantly reducing space occupation. When the angle gradually increases to 180°, it can be fully unfolded, thereby effectively extending the force arm of the pusher, making it easier to apply pushing or pulling force to the pusher through the folding component, making operation more convenient and labor-saving.

[0014] The pusher and the first rack are connected by welding, and the outside of the weld is covered with an anti-rust coating. The welding connection enables the pusher and the first rack to form a stable integral structure, ensuring the connection strength between the two and preventing breakage or loosening under stress. The anti-rust coating can effectively isolate air and moisture, prevent the weld from being affected by rust, and extend the service life of the clamping mechanism.

[0015] The hose is made of aging-resistant rubber material with an outer diameter of 3-5mm and a wall thickness of 0.5-1mm. The aging-resistant rubber material ensures that the hose is not prone to aging and cracking due to environmental factors (such as temperature changes and ultraviolet radiation) during long-term use, ensuring smooth gas flow between airbags. The specific outer diameter and wall thickness dimensions give the hose a certain degree of flexibility, making it easy to arrange with the structure of the coil, while also ensuring sufficient structural strength to prevent rupture due to internal air pressure.

[0016] The inner wall of the clamping component is provided with an anti-slip pad, which is made of silicone and has a uniformly distributed diamond-shaped anti-slip pattern on its surface. The silicone material has good elasticity and friction, and the diamond-shaped anti-slip pattern can further increase the friction between the clamping component and the connection part of the electronic device, effectively preventing relative slippage during clamping and ensuring the firmness of the clamping. The ring structure is injection molded from polytetrafluoroethylene (PTFE). PTFE has excellent corrosion resistance, wear resistance, and high temperature resistance. The injection molding process can ensure the structural accuracy and surface smoothness of the ring structure, making the ring structure less prone to damage during long-term use and allowing it to better cooperate with other components.

[0017] The first, second, and third airbags are all made of neoprene rubber with a thickness of 1-2 mm. Neoprene rubber has good elasticity, oil resistance, and aging resistance, and can fit tightly against the sealing surface after inflation to ensure a sealing effect. The 1-2 mm thickness design ensures that the airbag has sufficient expansion space and structural strength, while not affecting the overall installation compatibility of the sealing ring due to excessive thickness.

[0018] The first airbag is provided with an inflation nozzle at the top. The external thread of the inflation nozzle is connected to a sealing cap. The inner side of the sealing cap is provided with a rubber sealing ring that is compatible with the port of the inflation nozzle. The inflation nozzle can be used to conveniently inflate or deflate the airbag. The cooperation between the sealing cap and the rubber sealing ring can effectively prevent gas leakage after inflation and ensure the stability of the airbag's sealing pressure. The sealing element is made of elastic rubber and has a trapezoidal cross-section. Both the upper and lower ends of the sealing element are provided with inclined surfaces, which fit against the upper and lower walls of the inner cavity of the ring structure. The elastic rubber material gives the sealing element a certain deformation capability. The design of the trapezoidal cross-section and inclined surfaces can increase the contact area with the upper and lower walls of the inner cavity of the ring structure. During assembly, it can fit tightly through its own deformation, further enhancing the sealing performance of the inner cavity of the ring structure, forming a double guarantee with the airbag seal.

[0019] In summary, this application provides a sealing ring structure for sealing electronic devices, which has the following beneficial effects: This sealing ring structure for electronic devices utilizes a clamping mechanism. Through the cooperation of a pushing component, a folding component, a first rack, a gear, a second rack, and the clamping component, the sealing ring is securely clamped to the mounting location of the electronic device, preventing loosening during use and ensuring the stability of the seal. Simultaneously, the first, second, and third airbags in the sealing mechanism are connected by a flexible hose, allowing for synchronized inflation and expansion. The first airbag seals the upper end of the ring structure, while the second and third airbags seal the upper and lower ends of the inner cavity of the ring structure, respectively, creating a multi-directional, multi-layered sealing effect. This effectively improves sealing performance and better prevents water, dust, and other impurities from entering the electronic device. Combined with the stabilizing effect of the clamping mechanism, this further ensures the reliability and durability of the seal, thus providing more effective protection for the electronic device.

[0026] This application provides a technical solution; please refer to [link / reference]. Figures 1-5 The sealing ring structure for sealing electronic devices includes a ring body structure 1, a groove 2, and a sealing element 13. The groove 2 is evenly opened on the outside of the ring body structure 1 to provide positioning and storage space for the folding part 32 of the clamping mechanism 3. The sealing element 13 is set in the inner cavity of the ring body structure 1 to enhance the sealing performance of the inner cavity of the ring body structure 1 as a basic sealing layer.

[0027] The outer side of the ring structure 1 is uniformly provided with clamping mechanisms 3, which can fix the sealing ring from multiple directions and improve the overall stability. The clamping mechanism 3 includes a pusher 31, and a folding member 32 is rotatably connected to the outside of the pusher 31. The folding member 32 can change the direction of force and the length of lever arm by rotation. The other end of the pusher 31 is connected to a first rack 33. The upper end of the first rack 33 is meshed with a gear 34. The upper end of the gear 34 is meshed with a second rack 35. The gear 34 serves as an intermediate transmission component to realize the reverse motion conversion of the rack. The outside of the second rack 35 is connected to a clamping member 36. The clamping member 36 directly contacts the electronic device to complete the clamping action.

[0028] When the folding component 32 is manually rotated by the operator, it drives the pushing component 31 to move. The movement of the pushing component 31 causes the first rack 33 to move synchronously. The first rack 33, through meshing with the gear 34, drives the gear 34 to rotate. The gear 34 then drives the second rack 35 to move in the opposite direction, causing the clamping component 36 to move closer to the connection part of the electronic device, thereby achieving clamping and fixing between the sealing ring and the electronic device. This transmission process, through the precise coordination of the mechanical structure, efficiently converts the rotational force of the folding component 32 into the clamping force of the clamping component 36. Moreover, the multiple evenly distributed clamping mechanisms 3 can form a symmetrical clamping force, avoiding the skew caused by the sealing ring being subjected to force on one side, and effectively preventing the sealing ring from shifting or falling off during use. Even under conditions of vibration and collision, the stable clamping force can ensure the consistency of the connection between the sealing ring and the equipment, maintaining the continuity of the sealing effect. The outer part of the ring structure 1 is provided with a sealing mechanism 4, which forms a three-dimensional seal through the synergistic action of multiple airbags. The sealing mechanism 4 includes a first airbag 41, a second airbag 42, and a third airbag 43. The first airbag 41 is assembled at the upper end of the ring structure 1 to seal the gap at the top of the equipment. The second airbag 42 and the third airbag 43 are respectively embedded at the upper and lower ends of the inner cavity of the ring structure 1, corresponding to the upper and lower connecting surfaces of the inner cavity of the equipment. The first airbag 41, the second airbag 42, and the third airbag 43 are connected by a hose 44 to achieve synchronous gas distribution. The first airbag 41 is inflated by an externally added air pump, and the gas can flow quickly into the second airbag 42 and the third airbag 43 through the hose 44, causing the three airbags to inflate simultaneously. The first airbag 41, after inflating, can tightly fit against the upper surface of the electronic device, achieving a seal at the upper end of the ring structure 1. The second airbag 42 and the third airbag 43, after inflating, respectively fit against the electronic device components at the upper and lower ends of the inner cavity of the ring structure 1, thus forming sealing barriers from multiple locations. This improves the overall sealing performance of the electronic device and effectively prevents dust, moisture, and other impurities from entering the device. During the airbag inflation process, its surface adapts to the contour of the sealing surface, allowing it to fill even minor imperfections through deformation, ensuring a tight seal. This design offers greater adaptability compared to rigid sealing structures.

[0029] The inner cavity of the ring structure 1 is uniformly provided with grooves 11, which provide installation space for components such as racks and gears 34 and limit their range of motion. The upper and lower ends of the grooves 11 are slidably connected to guide members 39 through track grooves. The two sets of guide members 39 are respectively connected to the second rack 35 and the first rack 33. The guide members 39 can slide stably along the track grooves, providing precise guidance for the movement of the second rack 35 and the first rack 33, avoiding rack deviation or jamming during movement, and ensuring smoother and more stable transmission between the components of the clamping mechanism 3. The fit clearance between the guide member 39 and the track groove is controlled between 0.05 and 0.1 mm, which can ensure smooth sliding and minimize the radial wobble of the rack, ensuring the meshing accuracy with the gear 34.

[0030] Mounting seats 37 are connected to both sides of the second rack 35, serving as the connecting carrier for the elastic element 38. The elastic element 38 is externally connected to the mounting seats 37 and connected to the inner cavity of the groove 11. When the second rack 35 moves under the drive of the gear 34, the mounting seats 37 will pull or compress the elastic element 38 accordingly. The elastic restoring force generated by the elastic element 38 can buffer the mounting seats 37 and the second rack 35, making the clamping force of the clamping member 36 more gentle and uniform. At the same time, after the external force disappears, it can drive the second rack 35, gear 34, first rack 33 and other components to reset, which is convenient for the next use. The elastic coefficient of the elastic element 38 has been optimized. When the clamping member 36 contacts the equipment, the compression of the elastic element 38 is in the middle range of elastic deformation, which can provide sufficient buffering and ensure that the clamping force is within the preset range, such as 5-10N, to avoid clamping too loosely or too tightly.

[0031] The bottom of the ring structure 1 has a storage groove 12, and a rubber pad is embedded in the inner cavity of the storage groove 12. The inner cavity of the storage groove 12 is adapted to the outside of the first airbag 41. When the first airbag 41 is not inflated, it can be stored in the storage groove 12. The rubber pad can protect the first airbag 41 and prevent it from being damaged by direct friction with the ring structure 1. The adapting structure of the storage groove 12 can prevent the first airbag 41 from shaking randomly when it is not in operation. The inner wall of the storage groove 12 adopts a rounded corner transition design to avoid sharp edges scratching the surface of the first airbag 41. At the same time, the Shore hardness of the rubber pad is 30-40 degrees, which has good elasticity and can further absorb the impact of the vibration of the ring structure 1 on the airbag.

[0032] Magnets are installed on both the exterior of the folding component 32 and the interior of the slot 2. The two magnets attract each other, and when the folding component 32 rotates into the slot 2, the two magnets attract each other, firmly fixing the folding component 32 in the slot 2. This prevents the folding component 32 from accidentally unfolding or loosening when not in use, ensuring the overall stability of the clamping mechanism 3. The magnets are made of neodymium iron boron, possessing strong magnetic force, with an attraction force of 2-3N, sufficient to resist non-human-caused impacts. Simultaneously, the magnet surface is plated with a nickel layer, improving corrosion resistance and extending service life.

[0033] Both sides of the gear 34 are connected to mounted bearings. The two sets of mounted bearings are bolted to the inner cavity of the groove 11. The mounted bearings stably support the gear 34 within the groove 11, ensuring that the axis of the gear 34 remains fixed during rotation. This prevents the gear 34 from shifting and affecting the meshing accuracy with the first rack 33 and the second rack 35, thus ensuring the transmission efficiency and reliability of the clamping mechanism 3. The mounted bearings are of P6 precision grade, offering high rotational accuracy. They are filled with high-temperature grease, maintaining good lubrication within a temperature range of -20℃ to 100℃, ensuring smooth rotation of the gear 34.

[0034] The folding component 32 consists of at least two metal rods connected by a hinge, with the rotation angle between adjacent metal rods ranging from 0° to 180°. This structure allows the folding component 32 to be folded and unfolded flexibly. When the angle is 0°, it can be folded for storage, significantly reducing space occupation; when the angle gradually increases to 180°, it can be fully unfolded, effectively extending the lever arm of the pushing component 31. This makes it easier to apply pushing or pulling force to the pushing component 31 through the folding component 32, making operation more convenient and labor-saving. The metal rods are made of stainless steel, which has high strength and toughness. The pin diameter at the hinge is 3-5mm, ensuring that it is not easily bent or deformed under force, and the rotating parts are coated with a wear-resistant coating to reduce wear after long-term use.

[0035] The pusher 31 and the first rack 33 are connected by welding, and the outside of the weld is covered with an anti-rust coating. The welding connection enables the pusher 31 and the first rack 33 to form a stable integral structure, ensuring the connection strength between the two and preventing breakage or loosening under stress. The anti-rust coating can effectively isolate air and moisture, prevent the weld from being affected by rust, and extend the service life of the clamping mechanism 3.

[0036] The hose 44 is made of aging-resistant rubber, with an outer diameter of 3–5 mm and a wall thickness of 0.5–1 mm. This aging-resistant rubber material ensures that the hose 44 is not prone to aging and cracking due to environmental factors such as temperature changes and ultraviolet radiation during long-term use, ensuring smooth gas flow between the airbags. The specific outer diameter and wall thickness give the hose 44 both a certain degree of flexibility, facilitating its arrangement within the coil structure 1, and sufficient structural strength to prevent rupture due to internal air pressure. The inner wall smoothness Ra of the hose 44 is ≤0.8 μm, reducing gas flow resistance and controlling the inflation time difference of the three airbags to within 0.5 seconds, ensuring synchronized expansion.

[0037] The inner wall of the clamping component 36 is equipped with an anti-slip pad made of silicone. The surface of the anti-slip pad has evenly distributed diamond-shaped anti-slip patterns. Silicone has good elasticity and friction, and the diamond-shaped anti-slip patterns further increase the friction between the clamping component 36 and the connection part of the electronic device, effectively preventing relative slippage during clamping and ensuring the firmness of the clamping. The thickness of the anti-slip pad is 1-2mm, and the depth of the diamond pattern is 0.3-0.5mm. This design increases friction and also fills the tiny unevenness on the surface of the device through the deformation of the silicone, improving the fit. The ring structure 1 is injection molded from polytetrafluoroethylene (PTFE). PTFE has excellent corrosion resistance, wear resistance, and high temperature resistance. The injection molding process ensures the structural accuracy and surface smoothness of the ring structure 1, making it less prone to damage during long-term use and allowing for better cooperation with other components. PTFE has an extremely low coefficient of friction of 0.04-0.1, reducing wear during assembly with other components. The first airbag 41, the second airbag 42, and the third airbag 43 are all made of neoprene rubber, with a thickness of 1-2 mm. Neoprene rubber has good elasticity, oil resistance, and aging resistance, allowing it to tightly fit the sealing surface after inflation, ensuring a good seal. The 1-2 mm thickness design ensures sufficient expansion space and structural strength for the airbags without compromising the overall fit of the sealing ring due to excessive thickness. Neoprene rubber has an elongation rate of 800%-1000%, meeting the expansion requirements for sealing.

[0038] The top of the first airbag 41 is equipped with an inflation nozzle, and the external thread of the inflation nozzle is connected to a sealing cap. The inner side of the sealing cap is equipped with a rubber sealing ring, which is adapted to the port of the inflation nozzle. The inflation nozzle can be used to easily inflate or deflate the airbag. The cooperation between the sealing cap and the rubber sealing ring can effectively prevent gas leakage after inflation and ensure the stable sealing pressure of the airbag. The thread of the inflation nozzle is an M8 standard thread, which is highly versatile.

[0039] The seal 13 is made of elastic rubber and has a trapezoidal cross-section. Both the upper and lower ends of the seal 13 have inclined surfaces that fit against the upper and lower walls of the inner cavity of the ring structure 1. The elastic rubber material gives the seal 13 a certain degree of deformation capability. The trapezoidal cross-section and inclined surface design increase the contact area with the upper and lower walls of the inner cavity of the ring structure 1. During assembly, it can deform to fit tightly, further enhancing the sealing performance of the inner cavity of the ring structure 1, forming a double guarantee with the airbag seal. The seal 13 has a Shore hardness of 50-60 degrees and can deform by 10%-15% under a pressure of 5-10N during assembly, fully filling the gaps.

[0040] First, the clamping mechanism 3, which is evenly arranged on the outside of the ring structure 1, is used to clamp and fix the relevant components. The specific process is as follows: the worker pushes the pusher 31, which causes the pusher 31 to move the first rack 33. Since the first rack 33 is meshed with the gear 34, the movement of the first rack 33 will drive the gear 34 to rotate. The gear 34 is meshed with the second rack 35. The rotation of the gear 34 will then drive the second rack 35 to move. The movement of the second rack 35 will drive the clamping member 36 to move, thereby realizing the clamping action. Meanwhile, the folding member 32, externally rotatably connected to the pusher 31, can fold or unfold as the pusher 31 moves. The magnet on the outside of the folding member 32, which is magnetically attracted to the inner cavity of the slot 2, can fix the folding member 32 when it rotates into the slot 2. Regarding sealing, the sealing mechanism 4 externally provided to the ring structure 1 functions. The first airbag 41 is assembled at the upper end of the ring structure 1, and the second airbag 42 and third airbag 43 are respectively embedded at the upper and lower ends of the inner cavity of the ring structure 1. All three are connected by a hose 44. By inflating the first airbag 41, gas can enter the second airbag 42 and the third airbag 43 through the hose 44, causing the three airbags to expand, thereby achieving multi-directional sealing. The sealing member 13 is located in the inner cavity of the ring structure 1, further enhancing the sealing effect.

[0041] During the operation of the clamping mechanism 3, the grooves 11 evenly opened in the inner cavity of the ring structure 1 provide installation and movement space for related components. The guide members 39 at the upper and lower ends of the groove 11 are slidably connected to the second rack 35 and the first rack 33 respectively through the track groove, which guide the movement of the second rack 35 and the first rack 33 and ensure their stability. At the same time, the elastic members 38 connected to the mounting seats 37 on both sides of the second rack 35 are connected to the inner cavity of the groove 11. When the second rack 35 moves, the elastic members 38 will deform. When the external force disappears, the elastic force of the elastic members 38 can drive the second rack 35 to reset, thereby resetting the clamping member 36 and other components.

[0042] The storage groove 12 at the bottom of the ring structure 1 is used to store the first airbag 41. The rubber pad embedded in the inner cavity of the storage groove 12 can enhance the stability during storage. The inner cavity of the storage groove 12 is adapted to the outside of the first airbag 41, ensuring that the first airbag 41 can be well stored in it when not in use.

[0043] The seated bearings connected to the outer sides of the gear 34 are connected to the inner cavity of the groove 11 by bolts. The seated bearings provide stable support for the rotation of the gear 34, ensuring that the gear 34 will not deviate during rotation and ensuring accurate and reliable transmission of the first rack 33 and the second rack 35.

[0044] The folding component 32 is composed of at least two metal rods connected by a hinge, with a rotation angle range of 0°-180°. This allows the folding component 32 to fold or unfold flexibly during the movement of the pushing component 31, adapting to different working conditions.

[0045] The pusher 31 and the first rack 33 are connected by welding, and the outside of the weld is covered with an anti-rust coating. This connection method ensures the firmness of the connection between the pusher 31 and the first rack 33, and the anti-rust coating can prevent the weld from rusting and extend the service life of the components.

[0046] The hose 44 is made of aging-resistant rubber material with an outer diameter of 3-5 mm and a wall thickness of 0.5-1 mm. This material and size of the hose 44 can ensure the smooth flow of gas between the first airbag 41, the second airbag 42 and the third airbag 43. At the same time, the aging-resistant properties extend the service life of the hose 44.

[0047] The inner wall of the clamping component 36 is provided with a silicone anti-slip pad, which has a diamond-shaped anti-slip pattern evenly distributed on its surface. During the clamping process, it can increase the friction, prevent the clamped part from slipping, and enhance the clamping effect. The ring structure 1 is made of polytetrafluoroethylene injection molding material. This material has good performance and ensures the overall strength and stability of the ring structure 1.

[0048] The first airbag 41, the second airbag 42, and the third airbag 43 are made of neoprene rubber with a thickness of 1-2 mm. This material has good elasticity and sealing properties, and can fit tightly to the relevant parts after inflation, effectively achieving the sealing function.

[0049] The inflation nozzle at the top of the first airbag 41 is used to inflate the airbag. After inflation, the sealing cap connected to the external thread of the inflation nozzle can seal it. The rubber sealing ring on the inner side of the sealing cap is adapted to the port of the inflation nozzle, further ensuring airtightness. The sealing element 13 is made of elastic rubber with a trapezoidal cross-section. The inclined surfaces at the upper and lower ends fit against the upper and lower walls of the inner cavity of the ring structure 1, forming a seal inside the ring structure 1 and enhancing the overall sealing effect.
