Description

Technical Field

[0001] This utility model relates to the field of roller shutter door sealing technology, specifically to a high-temperature resistant sealing strip structure for fireproof roller shutter doors. Background Technology

[0002] Roller shutters consist of multiple articulated door panels linked together and are started by an electric motor. The shutters rotate up and down within fixed tracks, centered on a top roller. They are suitable for commercial storefronts, garages, shopping malls, hospitals, factories, mines, and other public places or residences. High-temperature resistant sealing strips are a sealing material specifically designed for fire-resistant roller shutters. Their main function is to maintain stable sealing performance in high-temperature environments, preventing flames, smoke, and heat from penetrating through the door gaps, thereby ensuring the safety of people and property.

[0003] A Chinese patent with publication number CN201310352202.8 discloses a high-temperature resistant material, a high-temperature resistant sealing strip, and a method for preparing the same. The key technical points are: the high-temperature resistant material is made by mixing methyl vinyl silicone rubber, methyl vinyl trifluoropropylene rubber, silica, a structure control agent, a colorant, a heat stabilizer, and a vulcanizing agent in a certain mass fraction ratio; using the high-temperature resistant material as raw material, the process includes the preparation and testing of the high-temperature resistant material; molding and vulcanization of the high-temperature resistant sealing strip; and post-processing and inspection of the high-temperature resistant sealing strip, resulting in a sealing strip with high-temperature resistance and oil resistance. The high-temperature resistant material prepared according to the raw material composition and mass fraction ratio provided in this invention has high-temperature resistance and oil resistance, and can be widely used in various high-temperature and oily environments.

[0004] Existing roller shutter door sealing strips are often installed using the following methods: adhesive method, where the sealing strip with glue is pasted onto the gap and a scraper or other tools are used to press it firmly to ensure a tight fit without gaps; screw-fixed method, where a screwdriver or other tools are used to fix the sealing strip to the door frame or roller shutter door with screws to ensure that the sealing strip is secure and does not fall off. Although the above installation methods can install the sealing strip, both adhesive and screw-fixed methods require the user to carry tools to complete the installation and removal work, which greatly affects the efficiency of the installation and removal of the sealing strip, thus reducing the practicality of the sealing strip.

[0032] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0033] like Figures 1 to 7 As shown, an embodiment of this utility model provides a high-temperature resistant sealing strip structure for fireproof rolling shutter doors, comprising:

[0034] Door frame 1; fixing block 7, which is fixedly connected to the inner wall of door frame 1, four fixing blocks 7 are provided, and the four fixing blocks 7 are symmetrically arranged in pairs; dovetail groove 8, which is opened on the side wall of fixing block 7, and two dovetail grooves 8 are provided; mounting strip 3, which has two rectangular grooves on its surface that are adapted to the size of fixing block 7, and two dovetail blocks 6 that are adapted to the size of dovetail groove 8 are fixedly connected to each of the two rectangular grooves. The dovetail blocks 6 are slidably connected to the dovetail groove 8. There are two mounting strips 3, and the surface of mounting strip 3 has a mounting groove; high temperature resistant sealing strip 2, which is snapped into the mounting grooves of the two mounting strips 3 on both sides; disassembly and assembly mechanism, which is set on the surface of mounting strip 3 and fixing block 7, for quick disassembly and assembly between mounting strip 3 and fixing block 7; fixing mechanism, which is set in the mounting groove of mounting strip 3, for fixing high temperature resistant sealing strip 2.

[0035] In this embodiment, the high-temperature resistant sealing strip 2 has the high-temperature resistance effect of existing technology (refer to the patent literature in the background art). The two sides of the high-temperature resistant sealing strip 2 are inserted into the mounting groove of the mounting strip 3, and the high-temperature resistant sealing strip 2 and the mounting strip 3 are connected by the fixing mechanism. Then, the two mounting strips 3 are closed to form a U-shape of the high-temperature resistant sealing strip 2, and the high-temperature resistant sealing strip 2 is placed in the door frame 1. At this time, the two mounting strips 3 are placed into the door frame 1 in sequence by the cooperation of the dovetail block 6 and the dovetail groove 8, and the high-temperature resistant sealing strip 2 is installed in the door frame 1 by the disassembly and assembly mechanism.

[0036] like Figures 1 to 7As shown, the disassembly and assembly mechanism includes two fixed plates 9 fixedly connected to the lower surface of the fixed block 7. A support rod 10 is fixedly connected to the surface of the fixed plate 9. A sliding sleeve 11 is slidably connected to the arc surface of the support rod 10. A locking block 12 is fixedly connected to one end of the sliding sleeve 11. A locking groove 21 adapted to the size of the locking block 12 is symmetrically opened on the rectangular groove of the surface of the mounting strip 3. A spring 14 is sleeved on the arc surface of the support rod 10. The two ends of the spring 14 are fixedly connected to the sliding sleeve 11 and the fixed plate 9 respectively. A cylindrical groove adapted to the size of the support rod 10 is opened at the end of the locking block 12 near the fixed plate 9. The support rod 10 is slidably connected to the locking block 12 through the cylindrical groove.

[0037] In this embodiment, the mounting strip 3 is pushed to slide into the door frame 1. As the mounting strip 3 descends, it presses against the locking block 12. At this time, the locking block 12 drives the sliding sleeve 11 to retract along the support rod 10 towards the fixing plate 9. The sliding sleeve 11 can also compress the spring 14 to retract. As the mounting strip 3 continues to slide down, the locking block 12 gradually becomes level with the slot 21 on the mounting strip 3. At this time, the locking block 12 loses the resistance of the mounting strip 3, and the spring 14, under its own elastic force, drives the sliding sleeve 11 and the locking block 12 to reset, so that the locking block 12 is inserted into the slot 21, thereby fixing the mounting strip 3 and completing the installation of the high-temperature resistant sealing strip 2.

[0038] like Figure 4 and Figure 6 As shown, four triangular blocks 22 are fixedly connected to the lower surface of the mounting strip 3, and the four triangular blocks 22 are in pairs. Several balls 23 are rotatably connected to the surface of the triangular blocks 22. An inclined plane is opened on the surface of the locking block 12, and two arc-shaped grooves 13 that are adapted to the size of the balls 23 are opened on the inclined plane of the locking block 12.

[0039] In this embodiment, when the mounting strip 3 slides down, the triangular block 22 first contacts the locking block 12 and squeezes the locking block 12, while the ball 23 contacts the arc-shaped groove 13 and slides in the arc-shaped groove 13. At this time, the ball 23 and the arc-shaped groove 13 cooperate to reduce the friction between the triangular block 22 and the locking block 12, which makes it easier for the mounting strip 3 to squeeze the locking block 12 to retract.

[0040] like Figure 6 and Figure 7 As shown, a connecting rope 15 is fixedly connected to the cylindrical grooves on the surfaces of the two locking blocks 12 that are close to each other. The connecting rope 15 is connected through the sliding sleeve 11, the support rod 10 and the fixing plate 9. A pull rope 16 is fixedly connected to the center of the connecting rope 15. The pull rope 16 is connected through the fixing block 7. A rotating rod 17 is rotatably connected to the surface of the fixing block 7. A handle 18 is fixedly connected to one end of the rotating rod 17. The pull rope 16 is fixedly connected to the rotating rod 17. An insert rod 19 is slidably connected to the surface of the handle 18. Several slots 20 that are adapted to the size of the insert rod 19 are opened on the surface of the fixing block 7.

[0041] In this embodiment, when the high-temperature resistant sealing strip 2 is installed, the insert rod 19 and the slot 20 are in a separate state. Rotating the handle 18 causes the rotating rod 17 to rotate, so that the pull rope 16 is wrapped around the rotating rod 17. As the pull rope 16 is gradually wrapped, the locking blocks 12 at both ends of the connecting rope 15 can be driven to approach each other. At this time, the locking blocks 12 are away from the slot 21, making it convenient for the user to disassemble the installation strip 3. The rotating rod 17 with the pull rope 16 wrapped around it can be fixed by inserting the insert rod 19 on the rotating rod 17 into the slot 20.

[0042] like Figure 3 As shown, the fixing mechanism includes several spikes 4 fixedly connected to the mounting grooves on the surface of the mounting strip 3. Several barbs 5 are fixedly connected to the surface of the spikes 4. The barbs 5 are inclined. Both the spikes 4 and the barbs 5 are conical structures.

[0043] In this embodiment, the mounting grooves of the two mounting strips 3 are aligned with the high-temperature resistant sealing strip 2 in sequence, and the mounting strips 3 are pushed so that the high-temperature resistant sealing strip 2 is inserted into the mounting groove of the mounting strip 3. At this time, the spikes 4 come into contact with the high-temperature resistant sealing strip 2, and the spikes 4 and barbs 5 are inserted into the high-temperature resistant sealing strip 2 together, thereby fixing the high-temperature resistant sealing strip 2. At the same time, the barbs 5 can increase the friction between the spikes 4 and the high-temperature resistant sealing strip 2 and reduce the possibility of separation between the high-temperature resistant sealing strip 2 and the spikes 4.

[0044] In this embodiment of the utility model (working principle), when installing the high-temperature resistant sealing strip 2, firstly, select or cut a suitable length of the high-temperature resistant sealing strip 2 according to the specifications of the roller shutter door. Then, align the mounting grooves of the two mounting strips 3 with the high-temperature resistant sealing strip 2 in sequence, and push the mounting strips 3 so that the high-temperature resistant sealing strip 2 is inserted into the mounting groove of the mounting strip 3. At this time, the spikes 4 come into contact with the high-temperature resistant sealing strip 2, and the spikes 4 and barbs 5 are inserted into the high-temperature resistant sealing strip 2 together, thereby fixing the high-temperature resistant sealing strip 2. At the same time, the barbs 5 can increase the friction between the spikes 4 and the high-temperature resistant sealing strip 2 and reduce the friction. In the case of separation between the high-temperature resistant sealing strip 2 and the spike 4, the two mounting strips 3 are brought together to form a U-shape with the high-temperature resistant sealing strip 2. The high-temperature resistant sealing strip 2 is then placed inside the door frame 1, and the dovetail blocks 6 on the two mounting strips 3 are aligned with the dovetail grooves 8 on the fixing block 7. The mounting strips 3 are then pushed to slide inwards into the door frame 1. As the mounting strips 3 descend, the triangular block 22 below it gradually contacts the inclined plane of the locking block 12 and presses against it. At this time, the locking block 12 causes the sliding sleeve 11 to retract along the support rod 10, and the sliding sleeve 11 can compress the spring 14 to retract. As the strip continues to slide downwards, the locking block 12 gradually aligns with the slot 21 on the mounting strip 3 at the same horizontal level. At this point, the locking block 12 loses the resistance of the mounting strip 3, and the spring 14, under its own elastic force, drives the sliding sleeve 11 and the locking block 12 to reset, allowing the locking block 12 to insert into the slot 21, thereby fixing the mounting strip 3 and completing the installation of the high-temperature resistant sealing strip 2. When it is necessary to replace or remove the high-temperature resistant sealing strip 2, simply rotate the handle 18 to rotate the rotating rod 17, causing the pull rope 16 to wind around the rotating rod 17. As the pull rope 16 gradually winds around, it can drive the two ends of the connecting rope 15. When the locking blocks 12 approach each other, they move away from the slots 21, making it easier for the user to disassemble the mounting strip 3. The rotating rod 17 with the pull rope 16 wrapped around it can be fixed by inserting the insert rod 19 on the rotating rod 17 into the slot 20. At this time, the user can rotate the four rotating rods 17 in sequence to make all the locking blocks 12 move away from the slots 21, thereby disassembling the two mounting strips 3. Then, simply pull the high-temperature resistant sealing strip 2 that needs to be disassembled to separate it from the mounting strip 3. Through the above operations, the disassembly and assembly of the high-temperature resistant sealing strip 2 can be completed quickly without the aid of tools.

[0045] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
