Description

Technical Field

[0001] This utility model relates to the field of sealing ring technology, specifically a high-efficiency heat-insulating silicone foam sealing ring. Background Technology

[0002] With the development of modern technology, various products produced by people need to use sealing products, including silicone foam sealing rings.

[0003] In existing technologies, silicone foam is produced through processes such as silicone extrusion and molding. Silicone foam sealing rings have advantages such as fine pores, long service life, and wear resistance.

[0004] However, the existing equipment still has some shortcomings. First, when the existing silicone foam sealing strip is compressed, a certain gap will be generated between the sealing ring and the contact surface, which will affect the sealing effect. Therefore, a high-efficiency heat-insulating silicone foam sealing ring is proposed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a high-efficiency heat-insulating silicone foam sealing ring to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency heat-insulating silicone foam sealing ring, comprising a sealing ring body and a first foamed silicone layer, wherein a sealing film is bonded to the inner wall of the first foamed silicone layer by an adhesive, a mesh layer is bonded to the inner wall of the sealing film by an adhesive, a rubber layer is fixedly connected to the inner side wall of the mesh layer, and a second foamed silicone layer is fixedly connected to the inner wall of the rubber layer.

[0007] By adopting the above technical solution, multiple sets of barrier strips come into contact with the object, providing multiple layers of protection to the gaps between the object and the sealing ring. This not only fills the gaps between the sealing ring body and the object but also prevents liquid from flowing in, improving the sealing effect. At the same time, the silicone rubber layer and mesh layer inside the sealing ring body provide support strength for the device and enhance the flame-retardant and heat-insulating effect. The air-filled cavity is filled with argon gas, which further improves the heat insulation effect. The air-filled cavity also improves the rebound effect of the device, allowing the sealing ring body to rebound in time, thereby ensuring the sealing effect.

[0008] Furthermore, the cross-section of the first foamed silicone layer is L-shaped, and multiple sets of barrier strips are fixedly connected to the outer wall of the first foamed silicone layer, the cross-section of the barrier strips being arched.

[0009] By adopting the above technical solution, the cross-section of the first foamed silicone layer is L-shaped, which can adhere to both sides of the object on one side and fill the bottom and side outer walls of the object. Multiple sets of barrier strips can adhere to the object for multi-layer protection, enhancing the sealing strength. The cross-section of the barrier strip is arched, which can disperse the force to the bottom and improve the stability of use.

[0010] Furthermore, the mesh layer has an air-filled cavity inside, and the cross-sectional shape of the mesh layer is arched.

[0011] By adopting the above technical solution, the inside of the mesh layer is provided with an air-filled cavity that can be filled with inert gases such as argon or krypton to further enhance the flame retardant effect. The cross-sectional shape of the mesh layer is arched, which can disperse the force and ensure the structural stability.

[0012] Furthermore, the rubber layer and the mesh layer are an integral structure, and the thickness of the first foamed silicone layer is greater than the thickness of the rubber layer.

[0013] By adopting the above technical solution, the thickness of the first foamed silicone layer is greater than the thickness of the rubber layer in order to ensure the fluffiness of the device and ensure a stable sealing and filling effect on the object.

[0014] Furthermore, an air inlet is fixed to one side of the outer wall of the sealing ring body, and the air inlet extends into the interior of the sealing ring body and communicates with the inflation cavity.

[0015] By adopting the above technical solution, the air inlet can be easily filled with inert gas into the air cavity using an air filling device.

[0016] Furthermore, a one-way valve is installed at the connection between the air inlet and the sealing ring body, and a sealing cap is threadedly connected to the port of the air inlet.

[0017] By adopting the above technical solution, a one-way valve is installed at the connection between the air inlet and the sealing ring body to prevent gas back leakage, and a sealing cap is threaded at the port of the air inlet to ensure the airtightness of the inflation cavity inside the equipment.

[0018] Furthermore, the interior of the inflatable cavity is filled with inert gas, and both the second foamed silicone layer and the mesh layer are made of silicone rubber.

[0019] By adopting the above technical solution, the second foamed silicone layer and the mesh layer are both made of silicone rubber, which can further improve the flame retardant and heat insulation effect.

[0020] In summary, the present invention has the following main advantages:

[0021] This invention uses multiple sets of barrier strips to contact the object, providing multiple layers of protection to the gaps between the object and the sealing ring. This not only fills the gaps between the sealing ring body and the object but also prevents liquid inflow, improving the sealing effect. Furthermore, the internal silicone rubber layer and mesh layer of the sealing ring body provide structural strength and enhance flame retardancy and heat insulation. The air-filled cavity further improves the heat insulation effect and enhances the rebound effect, allowing the sealing ring body to spring back quickly, thus ensuring a tight seal.

The inner side wall of the mesh layer 14 is fixedly connected with a rubber layer 13. The inner wall of the rubber layer 13 is fixedly connected with a second foamed silicone layer 16.

[0030] This utility model uses multiple sets of barrier strips 111 to contact the object, providing multiple layers of protection to the gaps between the object and the sealing ring body 1. This not only fills the gaps between the sealing ring body 1 and the object, but also prevents liquid from flowing in, improving the sealing effect. At the same time, the rubber layer 13 and mesh layer 14 inside the sealing ring body 1, which are made of silicone rubber, provide support strength to the device and enhance the flame-retardant and heat-insulating effects. The air-filled cavity 15 is filled with argon gas, which further improves the heat insulation effect. The air-filled cavity 15 can also improve the rebound effect of the device, allowing the sealing ring body 1 to rebound in time, thereby ensuring the sealing effect.

[0031] Please see Figure 2 - Figure 4 The first foamed silicone layer 11 has an L-shaped cross-section. Multiple sets of barrier strips 111 are fixedly connected to the outer wall of the first foamed silicone layer 11. The barrier strips 111 have an arched cross-section. By setting the above structure, the L-shaped cross-section of the first foamed silicone layer 11 can adhere to both sides of the object on one side, thereby filling the bottom and side outer walls of the object. Multiple sets of barrier strips 111 can adhere to the object for multi-layer protection, enhancing the sealing strength. The arched cross-section of the barrier strips 111 can disperse the force to the bottom, improving the stability of use.

[0032] Please see Figure 2 - Figure 4 The mesh layer 14 has an inflatable cavity 15 inside, and the cross-sectional shape of the mesh layer 14 is arched. By setting the above structure, the mesh layer 14 has an inflatable cavity 15 inside, which can be filled with inert gases such as argon or krypton to further enhance the flame retardant effect. The arched cross-sectional shape of the mesh layer 14 can disperse the force and ensure the structural stability.

[0033] Please see Figure 2 - Figure 4 The rubber layer 13 and the mesh layer 14 are an integral structure. The thickness of the first foamed silicone layer 11 is greater than the thickness of the rubber layer 13. By setting the above structure, the thickness of the first foamed silicone layer 11 is greater than the thickness of the rubber layer 13 to ensure the fluffiness of the device and ensure a stable sealing and filling effect on the object.

[0034] Please see Figure 1 - Figure 3 An air inlet 2 is fixed to one side of the outer wall of the sealing ring body 1. The air inlet 2 extends into the interior of the sealing ring body 1 and communicates with the inflation cavity 15. By setting the above structure, the air inlet 2 can be used to easily fill the inflation cavity 15 with inert gas using an inflation device.

[0035] Please see Figure 1 - Figure 2 A one-way valve is installed at the connection between the air inlet 2 and the sealing ring body 1, and a sealing cap is threadedly connected to the port of the air inlet 2. By setting the above structure, the one-way valve installed at the connection between the air inlet 2 and the sealing ring body 1 can prevent gas back leakage, and the sealing cap threadedly connected to the port of the air inlet 2 can ensure the airtightness of the inflation cavity 15 inside the equipment.

[0036] Please see Figure 2 - Figure 4 The air-filled cavity 15 is filled with inert gas. The second foamed silicone layer 16 and the mesh layer 14 are both made of silicone rubber. By setting the above structure, the second foamed silicone layer 16 and the mesh layer 14 are both made of silicone rubber, which can further improve the flame retardant and heat insulation effect.

[0037] The working principle of this utility model is as follows: When the sealing ring body 1 is used, multiple sets of right-angled vertical barrier strips 111 first come into contact with the object. The multiple sets of barrier strips 111 provide multiple layers of protection for the gap between the object, which not only fills the gap between the sealing ring body 1 and the object, but also prevents liquid from flowing in, thus improving the isolation and sealing effect. At the same time, the rubber layer 13 and the mesh layer 14 inside the sealing ring body 1, which are made of silicone rubber, provide support strength for the device and enhance the flame retardant and heat insulation effect. The air-filled cavity 15 is filled with argon gas, which further improves the heat insulation effect. The air-filled cavity 15 can also improve the rebound effect of the device, allowing the sealing ring body 1 to rebound in time, thereby ensuring the sealing effect.
