[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The following is combined with Figure 1-7 To further explain this application,

[0029] The present invention discloses an aluminum alloy early warning fireproof rolling shutter door, comprising a rolling shutter machine provided in a compartment, a reel driven by the rolling shutter machine, and a curtain surface 1 that is retracted along a guide rail and wound around the reel, wherein a plurality of modular pressure strips 2 are arranged at equal intervals on the curtain surface 1;

[0030] The combined pressure strip 2 includes two pressure plates 21 provided on the front and rear sides of the curtain surface 1, plugs 22 provided at both ends of the two pressure plates 21, and a protective cover 23 connecting the two pressure plates 21 and being threadedly connected to the plugs 22 by bolts and sleeved on the outer side of the curtain surface 1;

[0031] The two pressing plates 21 are fastened to the curtain surface 1 by a plurality of snap buttons 3 arranged at equal distances.

[0032] The pressure strips on both sides of the curtain surface 1 are fastened by snaps 3 to replace the traditional screw-nut connection, which does not require a long time to complete the fixation. In addition, there is no need to cut off the protruding parts of the fixed screws with a hand grinder as in the traditional technology, which can improve the installation efficiency and durability, while avoiding the safety hazards of cutting off the screw heads and maintaining the beautiful appearance of the door curtain.

[0033] The overall structural strength of the curtain surface 1 is improved by equidistantly arranged combined moldings 2. The design of the combined moldings 2 makes the curtain surface 1 more stable during the retraction and extension process, and is less likely to be twisted or deformed. The design of the combined moldings 2 makes the installation and removal of the curtain surface 1 simple and quick. At the same time, since the moldings and the curtain surface 1 are connected by snaps 3, maintenance is also more convenient, and damaged snaps 3 can be quickly replaced. The protective cover 23 in the combined moldings 2 can be put on the outer side of the curtain surface 1, which improves the fire resistance of the curtain surface 1 to a certain extent. When a fire occurs, the protective cover 23 can play a certain role in heat insulation and slow down the spread of the fire. In addition, the outer protective cover 23 is used to cooperate with the movement of the curtain fabric and the guide rail. The design of the combined moldings 2 makes the appearance of the curtain surface 1 more neat and beautiful. At the same time, due to the presence of the moldings and the plug 22, the curtain surface 1 is less likely to be offset or twisted during the retraction and extension process, thereby further enhancing its aesthetics.

[0034] like Figure 4 As shown, the pressing plate 21 includes a vertical plate 2101 and hook grooves 2102 turned outward from both ends of the vertical plate 2101. The two hook grooves 2102 at both ends and the vertical plate 2101 form a concave opening groove 2103. The pressing plate 21 is an integral extrusion molding structure.

[0035] like Figure 4 As shown, the plugs 22 are inserted into the concave opening grooves 2103 from both ends of the pressing plate 21 , and the plugs 22 are threadedly connected to the pressing plate 21 through hidden screws 4 .

[0036] The use of hidden screw 4 connection method avoids the impact of protruding screws on the appearance of the door curtain, making the door curtain more beautiful and neat. The hidden screw 4 connection method reduces the safety hazards caused by exposed screw heads, reduces the risk of scratches or impacts during use, and improves the safety of door curtain use. The design of plugs 22 being inserted into the concave opening groove 2103 from both ends of the pressure plate 21 simplifies the installation process, saves installation time, and improves installation efficiency.

[0037] The plug 22 is provided with a mounting hole 2201 , and the plug 22 is threadedly connected to the protective cover 23 via a screw that passes through the mounting hole 2201 , thereby facilitating the connection and fixation between the plug 22 and the protective cover 23 .

[0038] like Figure 5 As shown, a rectangular groove 2301 is formed on the outer side of the protective cover 23, and an inner thread hole 2302 is formed on the rectangular groove 2301. The arrangement of the rectangular groove 2301 and the inner thread hole 2302 facilitates the connection of a guide block that slides with the guide rail on the outer side of the curtain surface 1;

[0039] By connecting a guide block that cooperates with the guide rail to the outside of the curtain surface 1, the curtain surface 1 can be effectively prevented from deflecting or twisting during the retraction and extension process. This helps to maintain the linear movement of the curtain surface 1 and ensure the smooth operation of the rolling shutter door. The design of the rectangular groove 2301 and the inner thread hole 2302 allows the guide block to be tightly connected to the curtain surface 1, providing stable support, thereby reducing vibration and swinging when the curtain surface 1 moves and improving overall stability. The stable movement of the curtain surface 1 helps the fire shutter door to close quickly and accurately in an emergency, effectively isolate the fire source, and protect the safety of people and property. Reducing the deviation and twisting of the curtain surface 1 helps to reduce wear on the curtain surface 1, thereby extending the overall service life of the fire shutter door. Since the stability of the curtain surface 1 is improved, failures caused by deviation or twisting can be reduced, thereby simplifying maintenance work and reducing maintenance costs.

[0040] like Figure 6-7 As shown, the snap button 3 includes a pressing block A41 and a pressing block B42. The pressing block A41 is fixed with a sleeve rod 43 that passes through the pressure plate 21 and the through hole 2104 on the curtain surface 1. The pressing block B42 is provided with an insertion rod 44 that is inserted into the inner side of the sleeve rod 43 and buckled with the sleeve rod 43. The pressing block B42 is provided with a slot 45 that is located on the outside of the insertion rod 44 and cooperates with the sleeve rod 43.

[0041] After the pressing block A41 and the pressing block B42 are pressed and fastened together, the pressing block A41 and the pressing block B42 are respectively located in the concave opening grooves 2103 of the two pressure plates 21. The concave opening grooves 2103 are used to protect the pressing block A41 and the pressing block B42, that is, to protect the curtain surface 1. During the process of winding and unwinding the curtain surface 1, it will not be affected by the snaps 3 and will not scratch the curtain surface 1.

[0042] The pressing blocks A41 and B42 are located in the concave opening grooves 2103 of the two pressing plates 21 during the process of retracting and unreeling the curtain surface 1. This design can effectively protect the curtain surface 1 from being scratched or damaged by the structural part of the snap 3, especially when the curtain surface 1 moves repeatedly. Since the snap 3 structure will not cause damage to the curtain surface 1, the integrity of the curtain surface 1 is guaranteed in an emergency, which helps the fire shutter door to play its expected fire isolation function. The protective design of the pressing blocks A41 and B42 reduces the direct contact between the curtain surface 1 and the snap 3, extending the curtain surface. 1, thereby improving the durability of the entire fire shutter door. Due to the protective effect of the snap button 3 structure on the curtain surface 1, the frequency of inspection and replacement of the curtain surface 1 in daily maintenance work can be reduced, thereby simplifying the maintenance work. The design of the snap button 3 prevents the curtain surface 1 from unnecessary interference when it is retracted and extended, maintains the overall aesthetics of the door curtain, and avoids affecting the overall visual effect due to damaged or uncoordinated components. The structural design of the snap button 3 makes the operation of the curtain surface 1 smoother, without the interference of complex components, and the operator can more conveniently control the opening and closing of the fire shutter door.

[0043] When the roller shutter mechanism of this aluminum alloy early warning fire shutter door is activated, the reel begins to rotate, driving the curtain surface 1 to retract and extend along the guide rails. The curtain surface 1 is fixed by multiple modular pressure strips 2 arranged at equal intervals. These pressure strips are threadedly connected to the plug 22 via bolts and are sleeved on the outer surface of the curtain surface 1, thereby enhancing the structural strength of the curtain surface 1.

[0044] The design of the combined pressure strip 2 makes the curtain surface 1 more stable during the retraction and extension process, and is not prone to distortion or deformation. This ensures that the curtain surface 1 can remain flat even when retracted and extended at high speed, thereby effectively isolating the fire and smoke.

[0045] Each pressing plate 21 is connected to the curtain surface 1 by snap buttons 3 arranged at equal distances. This connection method replaces the traditional screw-nut connection, greatly simplifies the installation process, and does not require a long time to complete the fixation. The snap button 3 is composed of a pressing block A41 and a pressing block B42, and is connected by the buckle connection of a sleeve rod 43 and an insertion rod 44. During installation, it is only necessary to place the pressing block A41 and the pressing block B42 in the concave opening groove 2103 of the pressing plate 21 respectively, and then press the insertion rod 44 to insert the inner side of the sleeve rod 43 to complete the buckle connection. This design not only improves the installation efficiency, but also avoids the destruction of the aesthetics of the door curtain due to protruding screws.

[0046] In summary, this aluminum alloy early warning fire shutter door achieves multiple functions, including efficient installation, beautiful appearance, and stable performance, through its combined pressure strips 2, snap fasteners 3 connection, and protective cover 23. Its operating principle primarily utilizes a rolling door motor to drive the reel to retract and extend the curtain surface 1, while the pressure strips and snap fasteners 3 enhance the structural strength and stability of the curtain surface 1.

[0047] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
