Description

Technical Field

[0001] This utility model relates to the field of roller shutter technology, specifically an integrated fireproof roller shutter door. Background Technology

[0002] Fire-resistant roller shutters are fire-resistant and heat-insulating facilities suitable for large openings in buildings, playing a significant role in their design and installation. Widely used in fire-resistant partitions of industrial and civil buildings, fire-resistant roller shutters effectively prevent the spread of fire, protecting life and property, and are an indispensable fire protection facility in modern buildings.

[0003] Existing integrated fire-resistant roller shutters typically use a rotating shaft to roll up and down. During the release process, the roller shutter slides into a sliding track, which is equipped with rubber pads for sealing and blocking smoke. However, in order to ensure smooth raising and lowering of the roller shutter, gaps still exist between the rubber pads and the roller shutter, affecting the fire separation effect. This means that existing integrated fire-resistant roller shutters cannot fully perform their intended fire separation function in the event of a fire, posing a potential threat to the safety of people and property. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated fireproof rolling shutter door to solve the problem mentioned in the background art. Existing integrated fireproof rolling shutter doors usually use a rotating shaft to drive the rolling shutter door to roll up and release. During the release process, the rolling shutter door slides into the sliding track. In order to allow the rolling shutter door to rise and fall smoothly, gaps are usually left in the track, which affects the fire separation effect. As a result, existing integrated fireproof rolling shutter doors cannot fully play their due fire separation role in the event of a fire, posing a potential threat to the safety of people's lives and property.

[0005] To solve the above problems, this utility model provides the following technical solution: an integrated fireproof roller shutter door, comprising a roller shutter door frame, a fireproof part, and a sealing part:

[0006] The fireproof section is located inside the roller shutter frame. The fireproof section has a storage box located on the side of the roller shutter frame. A rewinding shaft is horizontally rotatable inside the storage box. A fireproof curtain is wound on the rewinding shaft. The rotation of the rewinding shaft drives the fireproof curtain to rewind and unwind. The sealing section is located inside the roller shutter frame. The sealing section has a limiting frame located inside the roller shutter frame. An inflatable sealing strip is provided on the inner side of the limiting frame. An air pump is provided on the outer side of the limiting frame. The air pump is connected to the inflatable sealing strip. The air pump inflates the inflatable sealing strip so that it abuts against the fireproof curtain.

[0007] By adopting the above technical solution, the fireproof curtain can be flexibly rolled up and released. In case of fire or other emergencies, the rolling shaft rotates to release the fireproof curtain, which can block the fire and smoke. At the same time, the air pump inflates the air-sealing strip, so that it is tightly pressed against the fireproof curtain, further enhancing the fireproof and smoke-blocking performance of the fireproof rolling shutter door and improving fire safety.

[0008] Preferably, the fireproof section also has a motor installed on the side of the storage box, the output end of which is connected to the winding shaft, and a rubber strip is provided at the bottom of the fireproof curtain, which abuts against the ground.

[0009] By adopting the above technical solution, the rotation of the winding shaft can be precisely controlled by the motor to realize the automated winding and unwinding operation of the fireproof curtain, improving the convenience of use. The rubber strip abuts against the ground, which can fill the gap between the fireproof curtain and the ground and prevent smoke and flames from spreading from the bottom.

[0010] Preferably, the sealing part also has a slot formed inside the limiting frame, and the side of the inflatable sealing strip is provided with a locking block, which is embedded in the slot and engaged with the limiting frame.

[0011] By adopting the above technical solution, the inflatable sealing strip can be securely installed on the limiting frame, preventing the inflatable sealing strip from shifting or falling off during use, ensuring that the air pump can function properly when inflating it, and enabling the inflatable sealing strip to effectively contact the fireproof curtain, thereby enhancing the sealing performance.

[0012] Preferably, there are two limiting frames, which are symmetrically arranged on both sides of the roller shutter door frame, and the inflatable sealing strip is inverted U-shaped.

[0013] By adopting the above technical solution, the fireproof curtain can be sealed from both sides of the roller shutter frame. The inverted U-shaped inflatable sealing strip can better fit the side and top edges of the fireproof curtain, forming a more comprehensive and tight sealing structure, effectively preventing smoke and flames from passing through the gaps on the side and top of the fireproof curtain.

[0014] Preferably, the side of the limiting frame has two through holes, and each of the two through holes is provided with an air pump. The two air pumps are connected to the same inflatable sealing strip through the two through holes. The cross-section of the inflatable sealing strip is a corrugated telescopic structure.

[0015] By adopting the above technical solution, two air pumps can be used to inflate the sealing strip simultaneously, making the inflation process faster and more uniform, and enabling the sealing strip to achieve a good sealing state in a short time.

[0016] Preferably, both the rubber strip and the inflatable sealing strip are made of silicone rubber.

[0017] By adopting the above technical solutions, the excellent high-temperature resistance, aging resistance and sealing properties of silicone rubber can be utilized. The rubber strips and inflatable sealing strips can still maintain stable performance in high-temperature environments and will not deform or be damaged due to high temperatures. This ensures that they can continue to play a fireproof and smoke-proof role in the event of a fire, and extends the service life of the fireproof rolling shutter door.

[0018] Preferably, the sealing part also has a contact switch embedded in the top of the mounting surface. The contact switch abuts against the rubber strip and is connected to the air pump via a wire.

[0019] By adopting the above technical solution, when the fireproof curtain is lowered and the rubber strip comes into contact with the contact switch on the ground, the contact switch is triggered and a signal is sent to the air pump through the wire. The air pump automatically starts to inflate the air sealing strip without manual intervention, which improves the response speed and ease of use of the fireproof rolling shutter door.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a sealing part, the fireproof curtain can be flexibly rolled up and released. In case of fire or other emergencies, the rolling shaft rotates to release the fireproof curtain, which plays a role in blocking the fire and smoke. At the same time, the air pump inflates the air-filled sealing strip, making it tightly abut against the fireproof curtain, further enhancing the fireproof and smoke-proof performance of the fireproof rolling shutter door and improving fire safety. When in use, when the rubber strip abuts against the contact switch on the ground, the contact switch is triggered, and a signal is sent to the air pump through the wire. The air pump automatically starts to inflate the air-filled sealing strip without manual intervention, which improves the response speed and ease of use of the fireproof rolling shutter door.

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

[0029] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: an integrated fireproof roller shutter door, including a roller shutter door frame 1, a fireproof part 2, and a sealing part 3.

[0030] Fireproof section 2 is located inside the roller shutter frame 1. Fireproof section 2 has a storage box 201 located on the side of the roller shutter frame 1. A retractable shaft 202 is laterally rotatable inside the storage box 201. A fireproof curtain 204 is wound onto the retractable shaft 202. The rotation of the retractable shaft 202 drives the fireproof curtain 204 to retract and release. Sealing section 3 is located inside the roller shutter frame 1. Sealing section 3 has a limiting frame 301 located inside the roller shutter frame 1. An inflatable sealing strip 304 is provided on the inner side of the limiting frame 301. An air pump 306 is installed on the side, which is connected to an inflatable sealing strip 304. The air pump 306 inflates the sealing strip 304 to make it come into contact with the fireproof curtain 204, which can realize the flexible rolling and unrolling of the fireproof curtain 204. In case of fire or other emergency, the rolling shaft 202 rotates to release the fireproof curtain 204, which can block the fire and smoke. At the same time, the air pump 306 inflates the sealing strip 304 to make it come into close contact with the fireproof curtain 204, further enhancing the fireproof and smoke-proof performance of the fireproof roller shutter door and improving fire safety.

[0031] Example 2

[0032] Please see Figure 3 , Figure 4 and Figure 5 This embodiment provides a technical solution: an integrated fireproof roller shutter door, including a fireproof part 2 and a sealing part 3.

[0033] A motor 203 is installed on the side of the storage box 201. The output end of the motor 203 is connected to the winding shaft 202. A rubber strip 205 is installed at the bottom of the fireproof curtain 204. The rubber strip 205 abuts against the ground. The rotation of the winding shaft 202 can be precisely controlled by the motor 203 to realize the automated winding and unwinding operation of the fireproof curtain 204, improving the convenience of use. The rubber strip 205 abuts against the ground and can fill the gap between the fireproof curtain 204 and the ground to prevent smoke and flames from spreading from the bottom.

[0034] A slot 302 is provided inside the limiting frame 301, and a locking block 305 is provided on the side of the inflatable sealing strip 304. The locking block 305 is embedded in the slot 302 and engaged with the limiting frame 301, so that the inflatable sealing strip 304 can be firmly installed on the limiting frame 301, preventing the inflatable sealing strip 304 from shifting or falling off during use, ensuring that the air pump 306 can function normally when inflating it, and enabling the inflatable sealing strip 304 to effectively abut against the fireproof curtain 204, thereby enhancing the sealing performance.

[0035] Two limit frames 301 are provided, and the two limit frames 301 are symmetrically arranged on both sides of the roller shutter door frame 1. The inflatable sealing strip 304 is inverted U-shaped, which can seal the fireproof curtain 204 from both sides of the roller shutter door frame 1. The inverted U-shaped inflatable sealing strip 304 can better fit the side and top edge of the fireproof curtain 204, forming a more comprehensive and tight sealing structure, effectively preventing smoke and flames from passing through the side and top gaps of the fireproof curtain 204.

[0036] The limiting frame 301 has two through holes 303 on its side. Each through hole 303 is equipped with an air pump 306. The two air pumps 306 are connected to the same inflatable sealing strip 304 through the two through holes 303. The inflatable sealing strip 304 has a corrugated telescopic structure, allowing the two air pumps 306 to simultaneously inflate the sealing strip 304, making the inflation process faster and more uniform, and enabling the sealing strip 304 to achieve a good seal in a short time.

[0037] Both rubber strip 205 and inflatable sealing strip 304 are made of silicone rubber. By utilizing the excellent high temperature resistance, aging resistance and sealing properties of silicone rubber, rubber strip 205 and inflatable sealing strip 304 can maintain stable performance in high temperature environments and will not deform or be damaged due to high temperature. This ensures that they can continue to play a fireproof and smoke-proof role in the event of a fire, and extend the service life of the fireproof rolling shutter door.

[0038] A contact switch 307 is embedded in the top of the installation ground. The contact switch 307 abuts against the rubber strip 205. The contact switch 307 is connected to the air pump 306 through a wire. When the fireproof curtain 204 is lowered, the contact switch 307 is triggered when the rubber strip 205 abuts against the contact switch 307 on the ground. The contact switch 307 sends a signal to the air pump 306 through the wire. The air pump 306 automatically starts to inflate the air-filled sealing strip 304 without manual intervention, which improves the response speed and ease of use of the fireproof rolling shutter door.

[0039] Working principle: Under normal circumstances, the fireproof curtain 204 is wound up on the winding shaft 202 inside the storage box 201. At this time, the air pump 306 is not working, and the inflatable sealing strip 304 is in a contracted, uninflated state, which does not affect the normal passage of personnel and goods. In case of emergency such as fire, the motor 203 starts, driving the winding shaft 202 to rotate and releasing the fireproof curtain 204 from the storage box 201. As the fireproof curtain 204 descends, the rubber strip 205 at its bottom gradually approaches the ground. When the rubber strip 205 comes into contact with the contact switch 307 embedded in the top of the mounting surface, the contact switch 307 is triggered. The contact switch 307 sends a signal to the air pump 306 through a wire. At this time, all four air pumps 306 located outside the limit frame 301 start simultaneously, inflating the inflatable sealing strip 304 through the perforation 303 on the side of the limit frame 301. Because the cross-section of the inflatable sealing strip 304 is a corrugated telescopic structure, it can fully expand during inflation. Furthermore, because the inflatable sealing strip 304 is secured by the side locking blocks... The rubber strip 305 is embedded in the slot 302 inside the limiting frame 301 and is securely installed on the limiting frame 301. Therefore, the inflated sealing strip 304 can tightly abut against the fireproof curtain 204 after inflation. The two inverted U-shaped inflatable sealing strips 304 symmetrically arranged on the limiting frames 301 on both sides of the roller shutter door frame 1 can form a comprehensive and tight sealing structure from the side and top edges of the fireproof curtain 204. At the same time, the rubber strip 205 abuts against the ground, filling the gap between the fireproof curtain 204 and the ground. In this way, the fireproof curtain... The fireproof curtain 204, together with the inflatable sealing strip 304 and the rubber strip 205, effectively blocks the spread of fire and smoke, enhances the fireproof and smoke-proof performance of the fireproof rolling shutter door, and improves fire safety. When the fire is extinguished, the motor 203 rotates in reverse, driving the winding shaft 202 to roll up the fireproof curtain 204 and put it back into the storage box 201. The rubber strip 205 leaves the contact switch 307, the air pump 306 stops working, and the inflatable sealing strip 304 deflates and retracts to its original state, returning to normal and waiting for the next emergency.
