Description
Technical Field
[0001] This utility model relates to the field of sealing strip technology, and in particular to a heat-resistant and environmentally friendly sealing strip. Background Technology
[0002] Sealing strips possess excellent elasticity and resistance to compression deformation, effectively isolating the carrier from the outside world and preserving items. Therefore, they are widely used in the construction industry. In the installation of doors and windows, heat-resistant and environmentally friendly sealing strips play a crucial role. They prevent air penetration and improve the building's thermal insulation performance. Especially in hot regions, they can block hot outdoor air from entering the room, providing insulation. Furthermore, their environmentally friendly characteristics meet the requirements of modern buildings for green materials. For example, in the door and window systems of some energy-efficient buildings, the use of heat-resistant and environmentally friendly sealing strips can effectively reduce the energy consumption of air conditioning and other refrigeration equipment, thus reducing energy waste.
[0003] The applicant discovered through a search that a Chinese patent discloses "A Highly Heat-Resistant Silicone Sealing Strip," with publication (announcement) number "CN 216478901 U." This patent mainly includes a sealing strip upper body set on a sealing body, and the sealing strip upper body is provided with a heat-resistant mechanism. Through the design of the heat-resistant strip, it has good heat resistance, allowing the silicone sealing strip body to expand uniformly inside and outside under high temperature conditions, while ensuring the overall sealing performance of the sealing strip. However, the above-mentioned prior art does not consider the connection method between sealing strips. Usually, the entire sealing strip is used. When a part of the sealing strip is damaged, such as by corrosion or wear, if there is no splicing, the entire sealing strip needs to be replaced. Replacing the entire sealing strip is a very complex and time-consuming task, and it is easy to waste materials. Therefore, we propose a heat-resistant and environmentally friendly sealing strip. Utility Model Content
[0004] The purpose of this utility model is to provide a heat-resistant and environmentally friendly sealing strip to solve the problem mentioned in the background art that the existing technology does not take into account the connection method between sealing strips. Usually, the entire sealing strip is used. When a part of the sealing strip is damaged, such as by corrosion or wear, if there is no splicing, the entire sealing strip needs to be replaced. Replacing the entire sealing strip is a very complicated and time-consuming task, and it is easy to waste materials.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat-resistant and environmentally friendly sealing strip, comprising a sealing reinforcement strip, a sealing protection strip and a convex strip fixedly installed at the top and bottom of the sealing reinforcement strip respectively, a connecting structure at both ends of the sealing reinforcement strip, the connecting structure comprising a first groove and a second groove, hook-and-loop fasteners and loop fasteners fixedly installed on the front and rear end surfaces of the sealing reinforcement strip respectively, a limit plug connected to the rear end of the sealing protection strip via a sealing convex strip, a second magnetic sticker connected to the rear end of the convex strip via a sealing convex block, a first magnetic sticker fixedly installed on the inner wall of the second groove, and a limit plug hole formed on the inner wall of the first groove.
[0006] As a preferred embodiment, the first groove is formed inside the front end of the sealing protective strip, the second groove is formed inside the front end of the convex strip, the sealing convex strip is fixedly installed on the rear end surface of the sealing protective strip, and the sealing protrusion is fixedly installed on the rear end surface of the convex strip.
[0007] As a preferred embodiment, the sealing protrusion is adapted to and engaged with the first groove, the sealing protrusion is adapted to and engaged with the second groove, the second magnetic sticker is fixedly installed on the side surface of the sealing protrusion away from the protruding strip, the first magnetic sticker and the second magnetic sticker are magnetically connected, and the hook-and-loop fastener and the loop fastener are adapted to each other.
[0008] As a preferred embodiment, two limiting blocks are provided and fixedly installed on the side surface of the sealing protrusion away from the sealing protection strip, and two limiting holes are provided and engaged with the two limiting blocks.
[0009] As a preferred embodiment, the bottom of the convex strip is provided with an adhesive film, the interior of the sealing reinforcement strip is provided with a sponge pad, and the interior of the sealing protection strip is a cavity.
[0010] As a preferred embodiment, the upper and lower surfaces of the sponge pad are provided with a plurality of uniformly distributed first fine pores, while the left and right surfaces are provided with a plurality of uniformly distributed second fine pores.
[0011] The technical effects and advantages of this utility model are as follows:
[0012] By setting up a connection structure, when splicing sealing strips for door and window installation, firstly, the sealing protrusion at one end of the sealing protection strip is precisely inserted into the first groove. At the same time, ensure that the limiting block is accurately inserted into the limiting hole to achieve a seamless connection. At this time, the two sections of the sealing protection strip can be in close contact. To further enhance the sealing effect, an appropriate amount of sealant can be applied to the connection. Meanwhile, the hook and loop fasteners on the sealing reinforcement strip should be tightly attached together to form a stable connection. Furthermore, the sealing protrusion on the convex strip should be inserted into the corresponding second groove. Then, by using the magnetic attraction between the first and second magnetic stickers, the convex strips are firmly connected, thus forming a complete sealing strip. The advantage of this splicing design is that when one section of the sealing strip is damaged, it can be easily disassembled and replaced, effectively avoiding the material waste caused by replacing the entire sealing strip due to partial damage, and improving the material utilization rate.
[0013] By setting up a sponge pad and an adhesive film, the bottom adhesive film of the convex strip can be peeled off to stick the convex strip inside the door and window, achieving good stability. A sponge pad is installed inside the sealing reinforcement strip. The sponge pad has good elasticity and plasticity. When the sealing strip is squeezed, the sponge pad can fill the gaps, making the seal tighter. There are many first and second micropores inside the sponge pad. These pores can effectively absorb and scatter sound. When sound encounters the sponge pad during propagation, some of the sound energy is absorbed by the air molecules in the pores, and the other part is continuously reflected and scattered between the pore walls, thereby weakening the sound intensity and playing a soundproofing role.

[0022] 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. Example 1:
[0023] Please see the appendix Figure 1 - Appendix Figure 4 and appendix Figure 6 - Appendix Figure 7 A heat-resistant and environmentally friendly sealing strip includes a sealing reinforcement strip 1. A sealing protection strip 2 and a convex strip 3 are fixedly installed on the top and bottom of the sealing reinforcement strip 1, respectively. Connecting structures 5 are provided at both ends of the sealing reinforcement strip 1. The connecting structures 5 include a first groove 501 and a second groove 504. Hook-face Velcro 503 and rough-face Velcro 506 are fixedly installed on the front and rear surfaces of the sealing reinforcement strip 1, respectively. A limiting insert 509 is connected to the rear end of the sealing protection strip 2 via a sealing convex strip 505. A second magnetic sticker 508 is connected to the rear end of the convex strip 3 via a sealing convex strip 507. A first magnetic sticker 502 is fixedly installed on the inner wall of the second groove 504. A limiting insert hole 510 is opened on the inner wall of the first groove 501. The first groove 501 is located inside the front end of the sealing protection strip 2. Two slots 504 are formed inside the front end of the convex strip 3. The sealing convex strip 505 is fixedly installed on the rear end surface of the sealing protection strip 2. The sealing protrusion 507 is fixedly installed on the rear end surface of the convex strip 3. The sealing convex strip 505 is adapted to and engaged with the first slot 501. The sealing protrusion 507 is adapted to and engaged with the second slot 504. The second magnetic sticker 508 is fixedly installed on the side surface of the sealing protrusion 507 away from the convex strip 3. The first magnetic sticker 502 and the second magnetic sticker 508 are magnetically connected. The hook-and-loop fastener 503 and the loop fastener 506 are adapted to each other. Two limiting inserts 509 are provided and fixedly installed on the side surface of the sealing convex strip 505 away from the sealing protection strip 2. Two limiting holes 510 are formed and engaged with the two limiting inserts 509.
[0024] The sealing protrusion 505 on the sealing protection strip 2 is inserted into the first groove 501, and the limiting plug 509 is inserted into the limiting plug hole 510. The connection is made with sealant. When disassembling, you only need to use a tool to cut the sealant along the connection seam to remove the two sections of the sealing protection strip 2 without affecting the splicing of the other sealing strip. The first magnetic sticker 502 and the second magnetic sticker 508 are connected magnetically. Generally, high-performance magnetic materials such as neodymium iron boron are selected to make the connection stable and easy to disassemble. When the hook-face hook and loop fastener 503 and the loop fastener 506 come into contact, the hook on the hook-face hook and loop fastener 503 will hook the fibers on the loop fastener 506 to achieve the connection. The splicing method makes it easy to replace a damaged section of the sealing strip, avoids material waste and also plays a certain role in environmental protection.
[0025] Specifically, when splicing sealing strips for door and window installation, first insert the sealing protrusion 505 at one end of the sealing protection strip 2 into the first groove 501, and insert the limiting block 509 into the limiting hole 510 to form a seamless connection. At this time, the two sealing protection strips 2 are in contact, and sealant can be applied to the connection to increase the connection strength. At the same time, the hook-and-loop fasteners 503 and the rough-sided hook-and-loop fasteners 506 on the sealing reinforcement strip 1 are attached together, and the sealing protrusion 507 on the convex strip 3 is inserted into the second groove 504. The convex strip 3 is connected together by the magnetic connection of the first magnetic sticker 502 and the second magnetic sticker 508 to form a complete sealing strip. If one section is damaged, it is easy to disassemble and replace it, avoiding the waste of materials caused by replacing the entire sealing strip. Example 2:
[0026] Please see the appendix Figure 1 - Appendix Figure 5 Furthermore, based on Embodiment 1, the bottom of the convex strip 3 is provided with an adhesive film 4, the interior of the sealing reinforcement strip 1 is provided with a sponge pad 6, the interior of the sealing protection strip 2 is a cavity, and the upper and lower surfaces of the sponge pad 6 are provided with a plurality of uniformly distributed first fine holes 7, while the left and right surfaces are provided with a plurality of uniformly distributed second fine holes 8.
[0027] The sealing strip 2 features a hollow internal structure that provides excellent elasticity. When the sealing strip is subjected to external pressure, the hollow part can be compressed, acting like a small buffer. This allows the sealing strip to be reused multiple times without losing its sealing performance. The hollow part can also form an air layer, which is a good heat and sound insulation medium. This air layer can block the transmission of heat and sound to a certain extent. The sealing strip is generally made of environmentally friendly, recyclable, or biodegradable materials, such as thermoplastic elastomers. These materials do not contain toxic or harmful substances and are environmentally friendly.
[0028] Specifically, by peeling off the bottom adhesive film 4 of the convex strip 3, the convex strip 3 can be pasted inside the door and window, providing good stability. A sponge pad 6 is installed inside the sealing reinforcement strip 1. The sponge pad 6 has good elasticity and plasticity. When the sealing strip is compressed, the sponge pad 6 can fill the gaps, making the seal tighter. The sponge pad 6 has many first fine pores 7 and second fine pores 8 inside. These pores can effectively absorb and scatter sound. When sound encounters the sponge pad 6 during propagation, part of the sound energy is absorbed by the air molecules in the pores, and the other part is continuously reflected and scattered between the pore walls, thereby weakening the sound intensity and playing a soundproofing role.
[0029] Working principle of this utility model: This utility model is a heat-resistant and environmentally friendly sealing strip. First, a rubber with high heat resistance is selected to ensure that the sealing strip formed has sufficient heat resistance. Then, multiple sealing strips are spliced together. In this process, the sealing protrusion 505 at one end of the sealing protection strip 2 is first inserted into the first groove 501, and the limiting block 509 is inserted into the limiting hole 510 to form a seamless connection. At this time, the two sealing protection strips 2 are in contact. Sealant can be applied at the joint to increase the connection strength. At the same time, the hook-and-loop fasteners 503 and the rough-and-loop fasteners 506 on the sealing reinforcement strip 1 are attached together, and the sealing protrusions 507 on the convex strip 3 are... Insert the strip into the second slot 504, and connect the convex strip 3 together through the magnetic connection of the first magnetic sticker 502 and the second magnetic sticker 508 to form a complete sealing strip. Then, peel off the bottom adhesive film 4 of the convex strip 3, and the convex strip 3 can be pasted inside the door and window, which provides good stability. A sponge pad 6 is installed inside the sealing reinforcement strip 1. The sponge pad 6 has good elasticity and plasticity. When the sealing strip is squeezed, the sponge pad 6 can fill the gaps, making the seal tighter. The many first fine holes 7 and second fine holes 8 set inside the sponge pad 6 can absorb sound energy and play a role in noise reduction. At this point, the whole process is completed.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
