Description

Technical Field

[0001] This utility model relates to the field of sealing technology, specifically to a heat-insulating sealing strip. Background Technology

[0002] Thermal insulation sealing strips are sealing products with excellent thermal insulation performance, playing a crucial role in various scenarios requiring insulation. They are typically made of special polymer materials, which themselves possess excellent thermal insulation properties and can effectively block heat conduction. Their compact and reasonable structural design allows them to form a highly efficient sealing barrier in gaps in doors, windows, pipes, industrial equipment, etc., after installation. On the one hand, in cold weather, they can prevent indoor heat from escaping, reducing heating energy consumption; on the other hand, in hot weather, they can block outdoor heat from entering the room, helping to keep the indoor environment cool. At the same time, these sealing strips also have excellent weather resistance, aging resistance, and flexibility, adapting to different environmental temperature and humidity changes. They are not easily deformed, cracked, or lose elasticity with long-term use, maintaining a good thermal insulation and sealing effect.

[0003] Current thermal insulation sealing strips experience wear on their contact surfaces during long-term use, which reduces their sealing effect and consequently their heat insulation performance. To address this, we propose a new thermal insulation sealing strip. Utility Model Content

[0004] The purpose of this utility model is to provide a heat-insulating sealing strip that can expand after the base surface of the heat-insulating sealing strip is worn, thereby eliminating the wear gap, ensuring the sealing and heat-insulating performance of the heat-insulating sealing strip, and extending the service life of the heat-insulating sealing strip. It solves the problem that the contact surface of the current heat-insulating sealing strip will wear during long-term use, thereby reducing its sealing effect and consequently reducing its heat-insulating performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat-insulating sealing strip, comprising a heat-insulating sealing strip body, wherein an air-filled cavity is provided inside the heat-insulating sealing strip body, and rubber plugs are fixedly installed near both ends inside the heat-insulating sealing strip body, and rubber protrusions are provided on the opposite sides of the two rubber plugs, and receiving chambers are provided inside the two rubber protrusions, and repair fluid is provided inside the two receiving chambers.

[0006] Preferably, extension strips are provided on both sides of the lower surface of the thermal insulation sealing strip body. The extension strips and the thermal insulation sealing strip body are integrally formed. The two extension strips form an installation groove under the thermal insulation sealing strip body, which facilitates the installation and fixing of the thermal insulation sealing strip body.

[0007] Preferably, the main body of the thermal insulation sealing strip is provided with a reinforcing cross strip inside. The reinforcing cross strip is integrally formed with the main body of the thermal insulation sealing strip, which can improve the strength of the main body of the thermal insulation sealing strip. At the same time, when the main body of the thermal insulation sealing strip is inflated, it helps to stabilize the shape of the main body of the thermal insulation sealing strip, thereby improving the sealing performance.

[0008] Preferably, the outer surface of the thermal insulation sealing strip body is provided with a thermal insulation coating, which improves the thermal insulation performance of the thermal insulation sealing strip body.

[0009] Preferably, the two rubber plugs have marking grooves on opposite sides, which facilitates the alignment of the inflation needle when the main body of the thermal insulation sealing strip is inflated using the inflation needle on the air cylinder, so that the inflation needle can pass through the receiving chamber better.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model, by setting up a thermal insulation sealing strip body, a rubber plug, an inflation cavity, a rubber protrusion, a receiving chamber, and a repair fluid, achieves the effect of expanding the thermal insulation sealing strip after the base surface is worn, thereby eliminating the wear gap and ensuring the sealing and insulation performance of the thermal insulation sealing strip, and extending the service life of the thermal insulation sealing strip. After the contact surface of the thermal insulation sealing strip is worn, the inflation needle on the inflation cylinder passes through the rubber plug and the receiving chamber, and fills the inflation cavity with gas, so that the thermal insulation sealing strip body expands to eliminate the wear gap and ensure the sealing and insulation performance of the thermal insulation sealing strip. After the inflation needle is pulled out, the repair fluid in the receiving chamber automatically repairs the needle hole left by the inflation pillow, preventing the gas inside the inflation cavity from flowing out along the needle hole. Furthermore, during the installation and use of the thermal insulation sealing strip body, when the gap to be sealed is larger than the original gap that the thermal insulation sealing strip body can seal, the gap can also be sealed by expanding the thermal insulation sealing strip body, thus improving the applicability of the thermal insulation sealing strip body.

[0012] 2. By setting a reinforcing cross strip, this utility model can improve the strength of the main body of the thermal insulation sealing strip. At the same time, when the main body of the thermal insulation sealing strip is inflated, it helps to stabilize the shape of the main body of the thermal insulation sealing strip, thereby improving the sealing performance.

[0013] 3. By setting a marking groove, this utility model makes it easier to align the inflation needle with the position when inflating the main body of the thermal insulation sealing strip using the inflation needle on the inflation cylinder, so that the inflation needle can pass through the receiving chamber better.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] like Figures 1-3 As shown, this utility model proposes a heat-insulating sealing strip, including a heat-insulating sealing strip body 2. The heat-insulating sealing strip body 2 has an internal inflation cavity 6. Inflation of the inflation cavity 6 by an air cylinder causes the heat-insulating sealing strip body 2 to expand. Rubber plugs 3 are fixedly installed near both ends of the heat-insulating sealing strip body 2, making the inflation cavity 6 a closed space. Each of the two rubber plugs 3 has a rubber protrusion 7 on its opposite side, and each of the two rubber protrusions 7 has a receiving chamber 9. Each of the two receiving chambers 9 contains a repair fluid 10. A reinforcing cross strip 4 is provided inside the heat-insulating sealing strip body 2. The reinforcing cross strip 4 improves the strength of the heat-insulating sealing strip body 2 and also helps stabilize the shape of the heat-insulating sealing strip body 2 when it expands, thereby improving the sealing performance.

[0021] In this embodiment, after the contact surface of the thermal insulation sealing strip body 2 is worn, the inflation needle on the air cylinder passes through the rubber plug 3 and the receiving chamber 9, and fills the interior of the inflation cavity 6 with gas, so that the thermal insulation sealing strip body 2 expands to eliminate the wear gap and ensure the sealing and thermal insulation performance of the thermal insulation sealing strip body 2. After the inflation needle is pulled out, the repair fluid 10 inside the receiving chamber 9 automatically repairs the needle hole left by the inflation pillow, preventing the gas inside the inflation cavity 6 from flowing out along the needle hole. In addition, during the installation and use of the thermal insulation sealing strip body 2, when the gap to be sealed is larger than the original gap that the thermal insulation sealing strip body 2 can seal, the gap can also be sealed by expanding the thermal insulation sealing strip body 2, thus improving the applicability of the thermal insulation sealing strip body 2.

[0022] Example 2

[0023] like Figures 1-3As shown, the present invention proposes a heat-insulating sealing strip. Compared with Embodiment 1, this embodiment further includes extension strips 1 on both sides of the lower surface of the heat-insulating sealing strip body 2. The extension strips 1 and the heat-insulating sealing strip body 2 are integrally formed. The two extension strips 1 form an installation groove under the heat-insulating sealing strip body 2, which facilitates the installation and fixing of the heat-insulating sealing strip body 2. The outer surface of the heat-insulating sealing strip body 2 is provided with a heat-insulating coating 5, which can improve the heat-insulating performance of the heat-insulating sealing strip body 2. Marking grooves 8 are provided on the opposite sides of the two rubber plugs 3.

[0024] In this embodiment, when the air inflator on the air cylinder is used to inflate the thermal insulation sealing strip body 2, the air inflator is aligned with the position through the marking groove 8 so that the air inflator can better pass through the receiving chamber 9.

[0025] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
