Description

Technical Field

[0001] This utility model relates to the technical field of roof sealing strips, specifically a double-bubble tube roof sealing strip that prevents water and air leakage. Background Technology

[0002] Sealing strips are products used to seal something, making it difficult to open. They serve functions such as shock absorption, waterproofing, sound insulation, heat insulation, dust prevention, and fixation. Existing sealing strips are widely used in the production of car roofs to facilitate sealing installation. However, there are still some defects in the use of car roof sealing strips. In use, existing car roof sealing strips generally adopt a single-layer sealing structure. When encountering rainy or snowy weather or when washing the vehicle, water seeps through the single-layer rubber strip and can no longer prevent water from continuing to penetrate, resulting in water leakage and affecting the comfort of the ride.

[0003] To overcome the above-mentioned defects, prior art 1 (Chinese patent application number 202020081784.6, application date 2020-01-15) provides a sealing strip for automotive sunroof glass, comprising a sealing strip body, glass PU, and a roof sheet metal component. The sealing strip body is disposed on the outside of the glass PU, and the roof sheet metal component is disposed on the outside of the sealing strip body. The sealing strip body is fixedly connected to the vehicle through the roof sheet metal component. The sealing strip body includes a sealing strip one and a sealing strip two, with a connecting block disposed between the sealing strip one and the sealing strip two. Multiple sealing strip creases are evenly disposed on the sealing strip one and the sealing strip two. A buffer layer is disposed inside the sealing strip one and the sealing strip two. Adhesive film facilitates adhesion, promoting the adhesive bond between the sealing strip one and the sealing strip two and the glass. Drainage channels facilitate the drainage of accumulated water, preventing water accumulation from affecting the sealing performance of the sealing strip body and the sunroof components. This device has a simple structure and is easy to operate and use.

[0004] While existing technologies reduce the leakage of sealing strips, the overall structure of the sealing strip is relatively complex due to the connection between sealing strip one, sealing strip two, and connecting block during operation. This increases the assembly difficulty during production, and the use of multiple layers of materials increases production costs. Furthermore, the need to connect sealing strip one and sealing strip two before use results in poor overall stability and an increased possibility of deformation, leading to poor overall sealing performance.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing double-bubble tube roof sealing strip for preventing water and air leakage. Therefore, we proposed a double-bubble tube roof sealing strip that can effectively solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a double-bubble tube roof sealing strip that prevents water and air leakage, in order to solve the problems mentioned in the background art. The current market uses sealing strip one, sealing strip two and connecting block to connect the sealing strip, which makes the overall structure of the sealing strip relatively complex, increases the assembly difficulty in the production process, and uses multiple layers of materials to set the sealing strip, which increases the production cost. The sealing strip one and sealing strip two need to be connected before use, which has poor overall stability and is prone to deformation, resulting in poor overall sealing effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a double-bubble tube roof sealing strip for preventing water and air leakage, comprising a sealing strip body, an inner sealing strip layer inside the sealing strip body, and fiber threads installed inside the inner sealing strip layer.

[0008] Preferably, the sealing strip body has a frame-shaped structure, the sealing strip body is partially wrapped around the outer side of the inner layer of the sealing strip, and the inner layer of the sealing strip is arranged in an "N" shape.

[0009] Preferably, the sealing strip body and the inner side of the inner layer of the sealing strip form a first bubble and a second bubble.

[0010] Preferably, the bottom of the inner layer of the sealing strip is provided with a first protective lip and a second protective lip.

[0011] Preferably, the inner side of the inner layer of the sealing strip is provided with an installation groove, and the inner side of the installation groove is provided with a first inclined groove and a second inclined groove.

[0012] Preferably, the first inclined groove and the second inclined groove are located on both sides of the mounting groove, the first inclined groove is located at the upper end of the second inclined groove, and the first inclined groove and the second inclined groove are formed in a triangle.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: This double-bubble tube roof sealing strip, designed to prevent water and air leakage, connects the sealing strip body to the inner layer, while a sealing coating is formed on the outer side of the sealing strip body. This not only makes the sealing strip body smoother to use, reduces friction between the sealing strip body and the roof, reduces wear, and extends the service life of the sealing strip body, but also reduces the problem of surface damage caused by long-term use of the sealing strip body, ensuring the integrity and sealing performance of the sealing strip body. The overall structure is simple, reducing the problem of increased installation and production costs caused by complex structures. The specific details are as follows:

[0014] (1) A sealing coating is formed on the outside of the sealing strip body, which not only makes the sealing strip body more convenient to use, but also reduces the problem of surface damage caused by long-term use of the sealing strip body. The overall structure is simple, which reduces the problem of increased installation and production costs caused by complex structure.

[0015] (2) After the sealing strip body is connected to the inner layer of the sealing strip, the first bubble and the second bubble are formed. The first bubble and the second bubble can protect both the inner and outer sides of the sealing strip body, reduce the intrusion of external wind and rain, enhance the overall sealing performance, and better prevent rainwater from seeping into the car and causing inconvenience.

[0016] (3) The first and second bubble are designed to deform according to the external environment, so that the inner layer of the sealing strip can be stably installed through the mounting groove in the first and second protective lips, ensuring that water and air leakage can be effectively prevented under various driving conditions.

[0017] (4) The sealing strip body and the inner layer of the sealing strip are easily squeezed. The first inclined groove and the second inclined groove can adapt to these deformations more flexibly. Through their own elastic deformation and adjustment of the tilt angle, they fill the gap caused by the deformation of the vehicle body, maintain a good sealing state, and effectively prevent water and air leakage.

[0018] (5) When the sealing strip body and the inner layer of the sealing strip are squeezed, the first inclined groove and the second inclined groove can guide the pressure to be transmitted in a specific direction, avoiding the situation of excessive or insufficient local pressure, and extending the service life of the sealing strip body and the inner layer of the sealing strip.

[0027] 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.

[0028] Example 1: In this example, the overall structure is simple, reducing the problem of increased installation and production costs caused by structural complexity, such as... Figures 1-7 The technical solution shown includes a sealing strip body 1, an inner sealing strip layer 2 inside the sealing strip body 1, and fiber threads 3 installed inside the inner sealing strip layer 2. The sealing strip body 1 has a frame-like structure and is semi-enclosed on the outside of the inner sealing strip layer 2. The inner sealing strip layer 2 is arranged in an "N" shape. The sealing strip body 1 and the inner sealing strip layer 2 are connected. The outside of the sealing strip body 1 is coated with Stahl 519 material, forming a sealing coating on the outside of the sealing strip body 1. This not only makes the sealing strip body 1 work more smoothly, reduces friction between the sealing strip body 1 and the roof, reduces wear, and extends the service life of the sealing strip body 1, but also reduces the cost of the sealing strip itself. The surface damage caused by long-term use of the sealing strip body 1 is eliminated, ensuring the integrity and sealing performance of the sealing strip body 1. The overall structure is simple, reducing the problem of increased installation and production costs caused by complex structures. The fiber lines 3 inside the inner layer 2 of the sealing strip provide additional support and strength, making the inner layer 2 less prone to deformation during installation and use, and ensuring stable sealing performance during use. This reduces the problem of poor sealing performance of the inner layer 2 of the sealing strip on bumpy roads or due to temperature changes. Furthermore, the stable structure of the fiber lines 3 facilitates the even distribution of external forces, improving the service life of the fiber lines 3 and thus improving the overall sealing performance.

[0029] Example 2: In this example, the first bubble 4 and the second bubble 5 are designed to deform easily according to the external environment, allowing the inner layer 2 of the sealing strip to be stably installed through the mounting grooves 8 in the first protective lip 6 and the second protective lip 7, ensuring effective prevention of water and air leakage under various driving conditions. Figures 1-7The technical solution shown has a first bubble 4 and a second bubble 5 formed on the inner side of the sealing strip body 1 and the inner layer 2. The bottom of the inner layer 2 is provided with a first protective lip 6 and a second protective lip 7. After the sealing strip body 1 and the inner layer 2 are connected, the first bubble 4 and the second bubble 5 are formed. The first bubble 4 and the second bubble 5 can protect both the inner and outer sides of the sealing strip body 1, reducing the intrusion of external wind and rain, enhancing the overall sealing performance, and better preventing rainwater from seeping into the vehicle and causing inconvenience. In addition, the first bubble 4 and the second bubble 5 can deform according to the external environment, so that the inner layer 2 of the sealing strip can be stably installed through the mounting groove 8 in the first protective lip 6 and the second protective lip 7, ensuring that water and air leakage can be effectively prevented under various driving conditions. Furthermore, the first bubble 4 and the second bubble 5 can provide sound insulation, further improving the quietness of the vehicle interior.

[0030] Example 3: In this example, the first inclined groove 9 and the second inclined groove 10 can guide the pressure to be transmitted along a specific direction, avoiding situations where the local pressure is too high or too low, thereby ensuring that the entire sealing area can achieve a good sealing effect, such as... Figures 1-7 The technical solution shown depicts an inner layer 2 of the sealing strip with an inner mounting groove 8. The inner side of the mounting groove 8 has a first inclined groove 9 and a second inclined groove 10, located on opposite sides of the mounting groove 8. The first inclined groove 9 is positioned above the second inclined groove 10, and the two grooves form a triangle. The presence of the first inclined groove 9 and the second inclined groove 10 on the sides of the mounting groove 8 allows the sealing strip body 1 and the inner layer 2 to be more flexibly adapted to deformations caused by compression during vehicle operation, utilizing their elastic deformation. The adjustment of the tilt angle fills the gaps caused by the deformation of the vehicle body, maintains a good sealing condition, effectively prevents water and air leakage, and when the sealing strip body 1 and the inner layer 2 of the sealing strip are squeezed, the first tilt groove 9 and the second tilt groove 10 can guide the pressure to be transmitted along a specific direction, avoiding the situation of excessive or insufficient local pressure, thereby ensuring that the entire sealing area can achieve a good sealing effect and extending the service life of the sealing strip body 1 and the inner layer 2 of the sealing strip. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
