Description

Technical Field

[0001] This invention relates to the field of sealing strips, and more particularly to an electromagnetic shielding sealing strip. Background Technology

[0002] Emergency windows are part of the emergency escape system. In a crisis, operators can break the window by smashing it or using other methods to escape. However, some emergency windows use organic glass or other special reinforced glass, which cannot be easily broken in a crisis.

[0003] For example, publication number "CN113501080A" discloses "an electromagnetic shielding stealth window for ships," comprising shielding glass, a window frame, a radar wave absorbing film, a radar wave damping strip, and an electromagnetic shielding strip. The window frame is detachably mounted on the hull wall via fasteners. Shielding glass is disposed within the inner ring of the window frame. The shielding glass includes an inner glass layer, an outer glass layer, and a metal shielding mesh disposed between the inner and outer glass layers. A radar wave absorbing film is disposed on the inner or outer sidewall of the shielding glass, and a radar wave damping strip is disposed between the shielding glass and the inner ring of the window frame. However, in practical applications, when tempered glass is used, in emergencies, it is impossible to quickly break the glass for escape, increasing the escape delay time. Summary of the Invention

[0004] In response to the problem mentioned in the background art that existing technologies using tempered glass cannot quickly break windows for escape, this invention provides an electromagnetic shielding sealing strip that can achieve the purpose of rapid escape, quickly separate the glass from the door frame, and escape without breaking the glass, saving escape time and reducing the risk of injury during the escape process.

[0005] The second objective of this invention is to achieve electromagnetic shielding effectiveness while ensuring support strength and saving material costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution.

[0007] An electromagnetic shielding sealing strip includes a sealing strip with one end connected to glass and the other end connected to a door frame. The sealing strip includes a main strip with a release groove, and a release core strip is engaged within the release groove. The sealing strip is positioned between the glass and the door frame. On both sides of the sealing strip are grooves that engage with the glass and the door frame, ensuring a tight connection between the glass, the door frame, and the sealing strip. The sealing strip consists of a main strip and a release core strip. The main strip is the main body, connected to the glass and the door frame on both sides. The release groove on the main strip engages with the release core strip, ensuring the stability of the release core strip under normal conditions. Simultaneously, because the release core strip engages with the release groove, it supports the main strip, preventing deformation and ensuring the stability of the glass. Since the release core strip and the release groove are engaged, the release core strip can engage with the release core strip. The trough separation mechanism, due to the sealing strip being made entirely of a gel material, allows for adequate deformation space. Therefore, in an emergency, the release core strip can be pulled out. At this point, the release trough loses its support from the release core strip, creating deformation space and disrupting the integrity of the sealing strip. Subsequently, when the glass is pushed, the glass causes the sealing strip to deform. Because the deformation space of the release trough is sufficient, the glass can be pushed out under the thrust, allowing it to detach directly from the door frame. This achieves rapid glass separation by disrupting the integrity of the connection between the glass and the door frame, ensuring efficient and simple separation. It ensures complete glass separation while avoiding the creation of glass shards that could injure people during emergency escape.

[0008] Preferably, the main rubber strip includes an inner core and a conductive silicon outer layer. The main rubber strip comprises an inner core and a conductive silicon outer layer. The main body material of the main rubber strip is ordinary rubber, while the overlap with the door frame glass (i.e., the conductive silicon outer layer) uses conductive silicone rubber. This ensures both the support strength of the rubber strip and electromagnetic shielding effectiveness. Furthermore, conductive silicone rubber has approximately twice the density of ordinary rubber and is more expensive. By using a double-layered main rubber strip, the use of conductive silicone rubber can be minimized, reducing the weight of the rubber strip and saving material costs. This solution achieves the second objective of the present invention.

[0009] Preferably, the sealing strip includes an inner strip portion and an outer strip portion, with the conductive silicon outer layer disposed on the outer strip portion. Disposing the conductive silicon outer layer on the outer strip portion effectively achieves electromagnetic shielding performance.

[0010] Preferably, the throwing groove is provided with a limiting groove, and the throwing core bar is provided with a limiting protrusion corresponding to the limiting groove. The limiting groove and the limiting protrusion are engaged and connected. The limiting groove on the throwing groove and the limiting protrusion on the throwing core bar, with the limiting groove and the limiting protrusion engaged and connected, can prevent the throwing core bar from coming out and ensure the stability between the glass and the door frame.

[0011] Preferably, the throwing groove includes a detachable opening. By setting the throwing groove to a detachable opening, the left and right sides of the main adhesive strip are separated. When the throwing core strip is pulled out, the left and right sides of the main adhesive strip are partially separated, thereby producing an appropriate deformation effect during the glass pushing process.

[0012] Preferably, a pull strap is provided between the throwing core and the throwing groove, and the pull strap extends out of the throwing groove. By providing a pull strap between the throwing core and the throwing groove, and extending the pull strap out of the throwing groove, the throwing core can be directly pulled outwards when the throwing core is pulled, thereby improving the efficiency of pulling out the throwing core.

[0013] Preferably, the main rubber strip is provided with inner and outer throwing grooves, and a through groove is provided between the inner and outer throwing grooves. Both the inner and outer throwing core strips are provided with pull-out core strips, and a pull-out strap is provided between the throwing core strip and the throwing groove. The pull-out strap passes through the through groove and connects to the pull-out core strip on the opposite side. Both the inner and outer sides of the main sealing strip are equipped with release grooves, allowing the glass to be opened from either the outside or inside in an emergency. When it is necessary to break the glass from the inside, the inner release core strip is pulled out, pushing the glass and deforming the sealing strip to push the glass out. A pull-out core strip is then installed between the release core strip and the release groove, connected to a pull strap. As the pull strap pulls the release core strip out of the release groove, it simultaneously pulls out the pull-out core strip on the other side, passing through the central slot and being pulled out from the side where the pull strap is being pulled. At this point, due to the pull-out core strip's detachment, a gap is created between the release core strip and the release groove on the opposite side, potentially disrupting the connection integrity and reducing the connection stability between the inner and outer sides of the sealing strip, thus making it more... The design makes it easier to push the glass open, avoiding increased difficulty in pushing it out due to the unchanged integrity of the opposite side. Simultaneously, the groove loses its supporting effect and creates deformation space, significantly reducing the integrity of the sealing strip and thus lowering the difficulty of pushing it out. Preferably, the pull-out core strip is positioned in a localized area to ensure quick extraction and avoid increasing resistance. Since the pull-out core strip is only positioned in a localized area, the deformable area is unevenly distributed after both the pull-out and release core strips are fully extracted. During the glass pushing process, areas that are easier to separate will appear. Compared to pushing the entire glass out at once, the process of localized separation leading to overall separation is more convenient and faster. Preferably, the pull-out core strip is positioned at a corner.

[0014] Preferably, the pull-out core strip includes a lever body disposed on the throwing core strip, and the pull-out core strip includes a support body that is fitted and connected to the through slot. Since the through slot is a hollow structure, a support body is provided on the pull-out core strip. The support body is fitted inside the through slot, and the pull strap is connected to the support body. During the pulling of the pull strap, the support body is driven to separate from the through slot, and then the support body drives the lever body to pass through the through slot.

[0015] Preferably, the inner and outer pull-out core strips are staggered. This staggered arrangement prevents interference between the inner and outer pull-out core strips. The positions of the pull straps on the inner and outer sides are also staggered accordingly, ensuring that the pull strap can pull the release core strip on this side and the pull-out core strip on the opposite side out in one continuous motion.

[0016] Preferably, the actuating body includes an arc-shaped surface positioned near the pull-out direction. Having an arc-shaped surface on the side of the actuating body near the pull-out direction reduces resistance during the pulling process, improving the smoothness of the pull-out.

[0017] The beneficial effects of this invention are as follows:

[0018] (1) It can achieve the purpose of rapid escape, quickly separate the glass from the door frame, and escape without breaking the glass, saving escape time and reducing the risk of injury during the escape process;

[0019] (2) It can ensure the support strength of the sealing strip and achieve electromagnetic shielding effectiveness;

[0020] (3) It can improve the efficiency of glass ejection and reduce the integrity of the inner and outer sealing strips. Attached Figure Description

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] Example 1:

[0037] like Figure 1 , 2 As shown, an electromagnetic shielding sealing strip includes a sealing strip 1, one end of which is connected to a glass 2, and the other end is connected to a door frame 3. The sealing strip 1 includes a main strip 4, on which a throwing groove 41 is provided, and a throwing core strip 5 is engaged within the throwing groove 41. The sealing strip 1 includes an inner strip portion 11 and an outer strip portion 12. A limiting groove 44 is provided in the throwing groove 41, and a limiting protrusion 51 is provided at the corresponding location of the limiting groove 44 for the throwing core strip 5. The limiting groove 44 and the limiting protrusion 51 are engaged. The throwing groove 41 includes a disconnectable opening 45. A pull strap 6 is provided between the throwing core strip 5 and the throwing groove 41, and the pull strap 6 extends out of the throwing groove 41.

[0038] A sealing strip 1 is placed between the glass 2 and the door frame 3. On both sides of the sealing strip 1, there are grooves that engage with the glass 2 and the door frame 3, ensuring a tight connection between the glass 2, the door frame 3, and the sealing strip 1. The sealing strip 1 consists of a main strip 4 and a release core strip 5. The main strip 4 is the main body and is connected to the glass 2 and the door frame 3 on both sides. A release groove 41 is provided on the main strip 4, which can engage with the release core strip 5, thus ensuring the stability of the release core strip 5 under normal conditions. Simultaneously, because the release core strip 5 engages with the release core strip 5... The groove 41 supports the main sealing strip 4, preventing deformation and ensuring the stability of the glass 2. Since the throwing core strip 5 and the throwing groove 41 are interlocked, the throwing core strip 5 can be separated from the throwing groove 41. Because the sealing strip 1 is made entirely of a gel material, it has sufficient deformation space. Therefore, the throwing core strip 5 can be pulled out in an emergency. At this time, the throwing groove 41 loses the support of the throwing core strip 5, creating deformation space and compromising the integrity of the sealing strip 1. Subsequently, when the glass 2 is pushed, the glass 2 causes the sealing strip 1 to deform. Due to the deformation of the throwing groove 41... With sufficient deformation space, the glass 2 can be pushed out under the thrust, allowing it to detach directly from the door frame 3. This rapid separation of the glass 2 is achieved by disrupting the integrity of the connection between the glass 2 and the door frame 3, ensuring efficient and simple separation. This process ensures complete separation of the glass 2 while preventing shattering and the creation of glass fragments that could injure people during an emergency escape. A limiting groove 44 is provided on the throwing chute 41, and a corresponding limiting protrusion 51 is provided on the throwing core 5. The limiting groove 44 and the limiting protrusion 51 engage to prevent the glass 2 from being thrown out of the frame. The core strip 5 is released to ensure the stability between the glass 2 and the door frame 3. The throwing groove 41 is set as a disconnection opening 45, thereby separating the left and right sides of the main adhesive strip 4. After the core strip 5 is pulled out, the left and right sides of the main adhesive strip 4 are partially disconnected, which can produce an appropriate deformation effect when pushing the glass 2. A pull strap 6 is set between the core strip 5 and the throwing groove 41, and the pull strap 6 extends out of the throwing groove 41. When the core strip 5 is pulled out, the pull strap 6 can be pulled outward to drive the core strip 5 out of the throwing groove 41, which improves the efficiency of pulling out the core strip 5.

[0039] The assembly and operation process of the electromagnetic shielding sealing strip in this embodiment is as follows: In this embodiment, the sealing strip 1 includes slots on both sides that engage with the glass 2 and the door frame 3. The glass 2 and the door frame 3 serve as the dividing line, and the sealing strip 1 is divided into an inner strip portion 11 and an outer strip portion 12. Both the inner strip portion 11 and the outer strip portion 12 are provided with a release groove 41. A release core strip 5 is connected to both the inner and outer release grooves 41. A limiting groove 44 is provided on the release groove 41, and a limiting protrusion 51 is provided on the corresponding release core strip 5. When the release core strip 5 is engaged inside the release groove 41, the limiting groove 44... 4 engages with the limiting protrusion 51 to prevent the throwing core strip 5 from coming out. A drawstring 6 also passes between the throwing core strip 5 and the throwing groove 41. The drawstring 6 extends out a disconnected opening. During use, when a person is trapped on one side of the inner rubber strip 11, the drawstring 6 is pulled. The drawstring 6 drives the throwing core strip 5 out of the throwing groove 41. Then the entire throwing core strip 5 is released out of the throwing groove 41. At this time, the throwing groove 41 on one side of the inner rubber strip 11 loses its support. The throwing groove 41 can act as a deformation space when pushing the glass 2 outward, so that the main rubber strip 4 can deform, thereby allowing the glass 2 to come out of the door frame 3 and form an emergency passage.

[0040] Example 2:

[0041] like Figure 1 As shown, in this embodiment, the main adhesive strip 4 includes an inner core 42 and a conductive silicon outer layer 43. The main adhesive strip 4 is made of ordinary rubber, while the overlap with the glass 2 of the door frame 3 (i.e., the conductive silicon outer layer 43) uses conductive silicone rubber. This ensures both the support strength of the adhesive strip and electromagnetic shielding effectiveness. Furthermore, conductive silicone rubber has approximately twice the density of ordinary rubber and is more expensive. By using a double-layered main adhesive strip 4, the amount of conductive silicone rubber used can be minimized, reducing the weight of the adhesive strip and saving material costs. The sealing strip 1 includes an inner strip portion 11 and an outer strip portion 12, with the conductive silicon outer layer 43 disposed on the outer strip portion 12. Disposing of the conductive silicon outer layer 43 on the outer strip portion 12 effectively achieves electromagnetic shielding effectiveness.

[0042] like Figure 1 , 2As shown, in addition to the above-mentioned technical features, this embodiment also includes a sealing strip 1. One end of the sealing strip 1 is connected to the glass 2, and the other end is connected to the door frame 3. The sealing strip 1 includes a main strip 4, and a throwing groove 41 is provided on the main strip 4. A throwing core strip 5 is engaged and connected in the throwing groove 41. A sealing strip 1 is placed between the glass 2 and the door frame 3. On both sides of the sealing strip 1, there are grooves that engage with the glass 2 and the door frame 3, ensuring a tight connection between the glass 2, the door frame 3, and the sealing strip 1. The sealing strip 1 consists of a main strip 4 and a core strip 5. The main strip 4 is the main body and is connected to the glass 2 and the door frame 3 on both sides. A core groove 41 is provided on the main strip 4, which engages with the core strip 5, ensuring the stability of the core strip 5 under normal conditions. Simultaneously, because the core strip 5 engages with the core groove 41, it supports the main strip 4, preventing deformation and ensuring the stability of the glass 2. Since the core strip 5 and the core groove 41 are engaged, the core strip 5... It can be separated from the throwing groove 41. Since the sealing strip 1 is made of a gel material, it can generate appropriate deformation space. Therefore, the throwing core strip 5 can be pulled out in an emergency. At this time, the throwing groove 41 loses the support of the throwing core strip 5 and generates deformation space. The integrity of the sealing strip 1 is destroyed. Then, when the glass 2 is pushed, the glass 2 causes the sealing strip 1 to deform. Since the deformation space of the throwing groove 41 is sufficient, the glass 2 can be pushed out under the action of the thrust, so that the glass 2 can be directly separated from the door frame 3. By destroying the integrity of the connection between the glass 2 and the door frame 3, the effect of quickly separating the glass 2 is achieved, thereby ensuring the efficiency of separating the glass 2 and making the process simpler. This allows the glass 2 to be completely separated, while avoiding the production of glass 2 fragments after the glass 2 is broken, which could injure people during emergency escape.

[0043] like Figure 1 , 2 As shown, a limiting groove 44 is provided in the throwing groove 41, and a limiting protrusion 51 is provided on the throwing core 5 corresponding to the limiting groove 44. The limiting groove 44 and the limiting protrusion 51 are engaged and connected. The limiting groove 44 on the throwing groove 41 and the limiting protrusion 51 corresponding to the throwing core 5 are engaged and connected, thereby preventing the throwing core 5 from coming out and ensuring the stability between the glass 2 and the door frame 3.

[0044] like Figure 1 , 2 As shown, the throwing groove 41 includes a separation opening 45. By setting the throwing groove 41 to a separation opening 45, the left and right sides of the main adhesive strip 4 are separated. After the throwing core strip 5 is pulled out, the left and right sides of the main adhesive strip 4 are partially separated, thereby producing an appropriate deformation effect during the pushing of the glass 2.

[0045] like Figure 1 , 2 As shown, a pull-out strap 6 is provided between the throwing core bar 5 and the throwing groove 41, and the pull-out strap 6 extends out of the throwing groove 41. With the pull-out strap 6 provided between the throwing core bar 5 and the throwing groove 41, and the pull-out strap 6 extending out of the throwing groove 41, when the throwing core bar 5 is pulled out, the pull-out strap 6 can be pulled outward to drive the throwing core bar 5 out of the throwing groove 41, thereby improving the efficiency of pulling out the throwing core bar 5.

[0046] Example 3:

[0047] like Figure 3 , 4 As shown in Figure 5, in this embodiment, the main rubber strip 4 is provided with inner and outer throwing grooves 41, and a through groove 46 is provided between the inner and outer throwing grooves 41. Both the inner and outer throwing core strips 5 are provided with pull-out core strips 7. A pull strap 6 is provided between the throwing core strip 5 and the throwing groove 41. The pull strap 6 passes through the through groove 46 and connects to the pull-out core strip 7 on the opposite side. The pull-out core strip 7 includes a toggle body 71 provided on the throwing core strip 5. The pull-out core strip 7 includes a support body 72 that is fitted and connected to the through groove 46. The inner and outer pull-out core strips 7 are staggered. The toggle body 71 includes an arc surface provided on the side close to the pull direction.

[0048] Both the inner and outer sides of the main sealing strip 4 are provided with throwing grooves 41, which can open the glass 2 from the outside or the inside as needed in an emergency. When it is necessary to break the glass 2 from the inside, the inner throwing core strip 5 is pulled out, pushing the glass 2 and causing the sealing strip 1 to deform, thus pushing the glass 2 out. A pull-out core strip 7 is provided between the throwing core strip 5 and the throwing groove 41, and the pull-out core strip 7 is connected to the pull strap 6. As the pull strap 6 pulls the throwing core strip 5 out of the throwing groove 41, it can simultaneously pull out the pull-out core strip 7 on the other side, and pass through the through groove 46 set in the middle to pull the pull strap 6. When one side is pulled out, the pull-out core strip 7 disengages, creating a gap between the release core strip 5 and the release groove 41 on the opposite side. This disrupts the connection integrity on the opposite side, reducing the connection stability between the inner and outer sides of the sealing strip 1. This makes it easier to push the glass 2 open, preventing increased difficulty in pushing out due to the unchanged integrity on the opposite side. Simultaneously, the groove 46 loses its supporting effect, creating a deformation space. The integrity of the sealing strip 1 at this point is significantly reduced, further lowering the difficulty of pushing out. Preferably, the pull-out core strip 7 is positioned at a localized location to ensure its rapid... The pull-out mechanism avoids increasing resistance during extraction. Since the pull-out core strip 7 is only located in a localized area, the deformable area is unevenly distributed after both the pull-out core strip 7 and the throwing core strip 5 are fully extracted. This results in easier separation during the pushing of the glass 2, making the process of localized separation leading to overall separation more convenient and faster than pushing the entire piece out at once. Preferably, the pull-out core strip 7 is located at a corner. Because the slot 46 is a hollow structure, a support body 72 is provided on the pull-out core strip 7. The support body 72 is fitted inside the slot 46, and the pull strap 6 is connected to the support body 72. Next, during the pulling of the drawstring 6, the support body 72 is separated from the slot 46. Then, the support body 72 drives the actuating body 71 to pass through the slot 46. The inner and outer drawstring cores 7 are staggered to avoid interference between the inner and outer drawstring cores 7. The positions of the inner and outer drawstrings 6 are also staggered accordingly to ensure that the drawstring 6 can drive the throwing core 5 on this side and the drawstring core 7 on the opposite side to come out in one go. The actuating body 71 is provided with an arc surface on the side close to the pulling direction, which can reduce the resistance encountered by the actuating body 71 during the pulling process and improve the smoothness of the pulling.

[0049] like Figure 1 , 2As shown, in addition to the above-mentioned technical features, this embodiment also includes a sealing strip 1. One end of the sealing strip 1 is connected to the glass 2, and the other end is connected to the door frame 3. The sealing strip 1 includes a main strip 4, and a throwing groove 41 is provided on the main strip 4. A throwing core strip 5 is engaged and connected in the throwing groove 41. A sealing strip 1 is placed between the glass 2 and the door frame 3. On both sides of the sealing strip 1, there are grooves that engage with the glass 2 and the door frame 3, ensuring a tight connection between the glass 2, the door frame 3, and the sealing strip 1. The sealing strip 1 consists of a main strip 4 and a core strip 5. The main strip 4 is the main body and is connected to the glass 2 and the door frame 3 on both sides. A core groove 41 is provided on the main strip 4, which engages with the core strip 5, ensuring the stability of the core strip 5 under normal conditions. Simultaneously, because the core strip 5 engages with the core groove 41, it supports the main strip 4, preventing deformation and ensuring the stability of the glass 2. Since the core strip 5 and the core groove 41 are engaged, the core strip 5... It can be separated from the throwing groove 41. Since the sealing strip 1 is made of a gel material, it can generate appropriate deformation space. Therefore, the throwing core strip 5 can be pulled out in an emergency. At this time, the throwing groove 41 loses the support of the throwing core strip 5 and generates deformation space. The integrity of the sealing strip 1 is destroyed. Then, when the glass 2 is pushed, the glass 2 causes the sealing strip 1 to deform. Since the deformation space of the throwing groove 41 is sufficient, the glass 2 can be pushed out under the action of the thrust, so that the glass 2 can be directly separated from the door frame 3. By destroying the integrity of the connection between the glass 2 and the door frame 3, the effect of quickly separating the glass 2 is achieved, thereby ensuring the efficiency of separating the glass 2 and making the process simpler. This allows the glass 2 to be completely separated, while avoiding the production of glass 2 fragments after the glass 2 is broken, which could injure people during emergency escape.

[0050] like Figure 1 , 2 As shown, the main adhesive strip 4 includes an inner core 42 and a conductive silicon outer layer 43, and the sealing adhesive strip 1 includes an inner adhesive strip portion 11 and an outer adhesive strip portion 12, with the conductive silicon outer layer 43 disposed on the outer adhesive strip portion 12.

[0051] The main rubber strip 4 includes an inner core 42 and a conductive silicon outer layer 43. The main body of the main rubber strip 4 is made of ordinary rubber, while the overlap with the glass 2 of the door frame 3 (i.e., the conductive silicon outer layer 43) is made of conductive silicone rubber. This ensures both the support strength of the rubber strip and the electromagnetic shielding performance. Moreover, conductive silicone rubber has a density about twice that of ordinary rubber and is more expensive. By setting a double-layer main rubber strip 4, the use of conductive silicone rubber can be reduced as much as possible, which can reduce the weight of the rubber strip and save material costs. Placing the conductive silicon outer layer 43 on the outer rubber strip part 12 can effectively achieve electromagnetic shielding performance.

[0052] like Figure 1 , 2 As shown, a limiting groove 44 is provided in the throwing groove 41, and a limiting protrusion 51 is provided on the throwing core 5 corresponding to the limiting groove 44. The limiting groove 44 and the limiting protrusion 51 are engaged and connected. The limiting groove 44 on the throwing groove 41 and the limiting protrusion 51 corresponding to the throwing core 5 are engaged and connected, thereby preventing the throwing core 5 from coming out and ensuring the stability between the glass 2 and the door frame 3.

[0053] like Figure 1 , 2 As shown, the throwing groove 41 includes a separation opening 45. By setting the throwing groove 41 to a separation opening 45, the left and right sides of the main adhesive strip 4 are separated. After the throwing core strip 5 is pulled out, the left and right sides of the main adhesive strip 4 are partially separated, thereby producing an appropriate deformation effect during the pushing of the glass 2.

[0054] like Figure 1 , 2 As shown, a pull-out strap 6 is provided between the throwing core bar 5 and the throwing groove 41, and the pull-out strap 6 extends out of the throwing groove 41. With the pull-out strap 6 provided between the throwing core bar 5 and the throwing groove 41, and the pull-out strap 6 extending out of the throwing groove 41, when the throwing core bar 5 is pulled out, the pull-out strap 6 can be pulled outward to drive the throwing core bar 5 out of the throwing groove 41, thereby improving the efficiency of pulling out the throwing core bar 5.

[0055] Example 4:

[0056] like Figure 6 , 7 As shown, unlike embodiment 3, the connecting groove on the throwing core 5 that fits with the pulling core 7 in this embodiment is a through groove structure. The pulling core 7 is partially set, so the position where the through groove is set on the throwing core 5 is also partially set. When the pulling core 7 is pulled out, the throwing core 5 at this point can generate a deformation compression space, thereby destroying the connection integrity at this point, making it easier for the glass 2 to come out.

[0057] The main rubber strip 4 is provided with inner and outer throwing grooves 41, and a through groove 46 is provided between the inner and outer throwing grooves 41. Both the inner and outer throwing core strips 5 are provided with pull-out core strips 7. A pull-out strap 6 is provided between the throwing core strip 5 and the throwing groove 41. The pull-out strap 6 passes through the through groove 46 and connects to the pull-out core strip 7 on the opposite side.

[0058] like Figure 3 , 4As shown in Figure 5, in addition to the above-mentioned technical features, in this embodiment, the main rubber strip 4 is provided with inner and outer throwing grooves 41, and a through groove 46 is provided between the inner and outer throwing grooves 41. Both the inner and outer throwing core strips 5 are provided with pull-out core strips 7. A pull-out strap 6 is provided between the throwing core strip 5 and the throwing groove 41. The pull-out strap 6 passes through the through groove 46 and connects to the pull-out core strip 7 on the opposite side. The pull-out core strip 7 includes a toggle body 71 provided on the throwing core strip 5. The pull-out core strip 7 includes a support body 72 that is fitted and connected to the through groove 46. The inner and outer pull-out core strips 7 are staggered. The toggle body 71 includes an arc surface provided on the side close to the pull-out direction.

[0059] Both the inner and outer sides of the main sealing strip 4 are provided with throwing grooves 41, which can open the glass 2 from the outside or the inside as needed in an emergency. When it is necessary to break the glass 2 from the inside, the inner throwing core strip 5 is pulled out, pushing the glass 2 and causing the sealing strip 1 to deform, thus pushing the glass 2 out. A pull-out core strip 7 is then provided between the throwing core strip 5 and the throwing groove 41, and the pull-out core strip 7 is connected to the pull strap 6. As the pull strap 6 pulls the throwing core strip 5 out of the throwing groove 41, it can simultaneously pull out the pull-out core strip 7 on the other side, and pull it out through the through groove 46 in the middle and out from the side that pulls the pull strap 6. At this time, because the pull-out core strip 7 is pulled out, a gap is also created between the throwing core strip 5 on the other side and the throwing groove 41, which can damage the integrity of the connection on the other side, thereby reducing the connection stability of the inner and outer sides of the sealing strip 1. Qualitative design makes it easier to push the glass 2 open, avoiding increased difficulty in pushing out due to the unchanged integrity of the opposite side. Simultaneously, since the groove 46 loses its supporting effect, it also forms a deformation space, significantly reducing the integrity of the sealing strip 1 and thus lowering the difficulty of pushing out. Preferably, the pull-out core strip 7 is positioned in a localized location to ensure quick extraction, avoiding increased resistance. Since the pull-out core strip 7 is only positioned in a localized location, the deformable area is unevenly distributed after both the pull-out core strip 7 and the throwing core strip 5 are extracted. During the pushing of the glass 2, more easily separated sections appear, making the process of localized separation leading to overall separation more convenient and faster than pushing out the entire piece at once. Preferably, the pull-out core strip 7 is positioned at a corner.

[0060] Since the slot 46 is a hollow structure, a support body 72 is provided on the pull-out core strip 7. The support body 72 is fitted inside the slot 46. The pull strap 6 is connected to the support body 72. When the pull strap 6 is pulled, the support body 72 is separated from the slot 46. Then the support body 72 drives the actuating body 71 to pass through the slot 46.

[0061] The inner and outer pull-out core strips 7 are staggered. The staggered arrangement of the inner and outer pull-out core strips 7 can avoid interference between the inner and outer pull-out core strips 7. The positions of the inner and outer pull straps 6 are also staggered accordingly, so as to ensure that the pull straps 6 can drive the throwing core strip 5 on this side and the pull-out core strip 7 on the opposite side to come out in one go.

[0062] The actuating body 71 includes an arc-shaped surface located near the pull-out direction. By providing an arc-shaped surface on the side of the actuating body 71 near the pull-out direction, the resistance encountered by the actuating body 71 during the pulling process can be reduced, thereby improving the smoothness of the pulling process.
