[0038] like Figure 1 、 Figures 3 to 5As shown, a fireproof rolling shutter door 1 includes a frame 10 and a water spray assembly 20, the water spray assembly 20 includes a sleeve rod 21, a conduit 22, a fan blade 23 and a locking member 24, the locking member 24 is arranged on one end of the frame 10, the sleeve rod 21 is slidably arranged on the frame 10, and one end of the sleeve rod 21 is engaged with the locking member 24, the conduit 22 is slidably arranged in the frame 10, one end of the conduit 22 is used to connect the water pipe, the fan blade 23 is arranged on the side of the frame 10 away from the sleeve rod 21, and a spray hole 231 is opened on the fan blade 23. When the sleeve rod 21 is disengaged from the locking member 24, the sleeve rod 21 drives the conduit 22 to slide close to the fan blade 23, so that the end of the conduit 22 away from the water pipe is connected to the fan blade 23, thereby making the water pipe communicate with the spray hole 231.

[0039] It should be noted that a perforated plate 11 and two support plates 12 are provided within the frame 10. The perforated plate 11 divides the interior of the frame 10 into a first chamber and a second chamber. The perforated plate 11 is provided with a plurality of perforations 111, each of which is spaced apart in a straight line. Furthermore, the two support plates 12 are spaced apart on the perforated plate 11, and both support plates 12 are located on either side of each perforation 111. Furthermore, a conduit 22 is located between the two support plates 12. The conduit 22 is provided with a plurality of sleeves 221, each of which is spaced apart in a straight line on a side surface of the conduit 22, and each sleeve 221 corresponds to each perforation 111. Each sleeve 221 is slidably provided within each perforation 111, allowing the conduit 22 to slide laterally relative to the frame 10, thereby allowing each sleeve 221 on the conduit 22 to slide laterally relative to each perforation 111 into the second chamber.

[0040] It should be noted that the sleeve rod 21 is slidably set on the frame 10, and the sleeve rod 21 is located in the first chamber, and the sleeve rod 21 is a U-shaped structure. The two ends of the sleeve rod 21 are respectively located on the outside of the two support plates 12, so that the sleeve rod 21 can cover the two support plates 12. In this way, the sleeve rod 21, the orifice plate 11 and the two support plates 12 together surround the catheter 22, and the catheter 22 can slide horizontally between the sleeve rod 21, the orifice plate 11 and the two support plates 12, and each sleeve head 221 on the catheter 22 can extend from each through-hole 111 on the orifice plate 11.

[0041] like Figures 3 to 5As shown, in one embodiment, the conduit 22 is provided with protrusions 222 on both sides perpendicular to each sleeve 221. The protrusions 222 are spaced apart and correspond one to one on both sides of the conduit 22. A plurality of air-avoidance grooves 121 are provided on both support plates 12. Each air-avoidance groove 121 is opened in the axial direction of the through-hole 111. The air-avoidance grooves 121 on the two support plates 12 are aligned with each other, and each air-avoidance groove 121 corresponds one to one with each protrusion 222. The middle portion of each protrusion 222 is located in the air-avoidance groove 121, so that each protrusion 222 can slide in the air-avoidance groove 121, thereby enabling the conduit 22 to slide laterally relative to the two support plates 12. Furthermore, a plurality of inclined grooves 2111 are provided on both sides of the sleeve rod 21 . The inclined grooves 2111 are provided in the same direction and are spaced apart. The inclined grooves 2111 on both sides correspond to each other one by one. One end of each boss 222 passes through each avoidance groove 121 and is located in each inclined groove 2111 .

[0042] It should be noted that when the sleeve rod 21 is lifted and slid relative to the frame 10 , the inclined grooves 2111 on the sleeve rod 21 push and push the protruding columns 222 to slide laterally along the avoidance groove 121 toward or away from the orifice plate 11 .

[0043] like Figure 1 、 Figure 9 As shown, in one embodiment, the fan blade member 23 is a rolling shutter door structure formed by splicing together a number of fan blade plates, wherein one fan blade plate includes a front leaf, a rear leaf, a fireproof plate 232 and two T-blocks 2312. Hook grooves are provided on both sides of the front leaf so that the front leaves can be rotatably connected to each other. Two T-blocks 2312 are provided on the inner side surfaces of both ends of the front leaf. The fireproof plate 232 is placed on the front leaf and is located between the two T-blocks 2312. Both ends of the rear leaf are connected to the side of the two T-blocks 2312 away from the front leaf, so that the rear leaf and the front leaf jointly wrap the fireproof plate 232 through the two T-blocks 2312.

[0044] It should be noted that a through hole 23121 is provided on both T-blocks 2312, a plurality of spray holes 231 are provided on both the front and rear leaves, and a passage connected to the two through holes 23121 and the plurality of spray holes 231 is provided in the fireproof plate 232, so that the through holes 23121 on the two T-blocks 2312 and the spray holes 231 are connected to each other.

[0045] like Figure 1 、 Figure 3 As shown, in one embodiment, a slide groove 13 is provided on a side surface of the frame 10 away from the sleeve rod 21, so that the second chamber can be connected to the outside of the frame 10. Furthermore, the fan blade 23 is spliced ​​by a plurality of fan blade plates, so that there are a plurality of T-blocks 2312 on one end of the fan blade 23, and one end of each T-block 2312 is in the same direction.

[0046] It should be noted that when one end of each T-block 2312 slides into the chute 13, the fan blade 23 can be fixed to the frame 10, and the through hole 23121 of each T-block 2312 can also be connected to the second chamber. Furthermore, the number of T-blocks 2312 spliced ​​into the fan blade 23 is consistent with the number of perforations 111, so that after each sleeve 221 passes through the perforations 111 and extends into the second chamber, it can be connected to each T-block 2312 in a one-to-one correspondence, so that each sleeve 221 can be connected to each through hole 23121. Furthermore, the inner side wall of the sleeve 221 and the T-block 2312 sleeve end is provided with an inner bevel, and the outer side wall of the T-block 2312 inserted into the sleeve 221 end is provided with an outer bevel, so that the sleeve 221 and the T-block 2312 can be smoothly plugged in. Furthermore, the water spray assembly 20 also includes a conical ring 28, the two ends of the conical ring 28 are connected to each other, and the aperture sizes at the two ends of the conical ring 28 are inconsistent. The end of the conical ring 28 with a smaller aperture is arranged on the end of the sleeve 221 facing the T-block 2312, so that when the T-block 2312 is not aligned with the sleeve 221, the conical ring 28 can guide the sleeve 221 to be sleeved on the T-block 2312.

[0047] like Figures 1 to 3 As shown, in one embodiment, the locking member 24 includes a sensing bead 241 and a clamping block 242 . The clamping block 242 is slidably disposed on the frame 10 . One end of the clamping block 242 abuts against the sensing bead 241 , and the other end of the clamping block 242 is clamped with the sleeve rod 21 .

[0048] It should be noted that a post hole is formed on one end of the frame 10, and one end of the sleeve rod 21 extends from the post hole. Furthermore, two slide rails 14 are provided on the outer wall of the end of the frame 10 where the post hole is formed. The two slide rails 14 are respectively located on either side of the post hole and are arranged along the axial direction of the through hole 111. Furthermore, the clamping block 242 has a U-shaped structure, and the two ends of the clamping block 242 are slidably arranged on the two slide rails 14. Furthermore, two engaging springs 243 are provided, and the two engaging springs 243 are both arranged on the frame 10 perpendicular to the slide rails 14, so that the two engaging springs 243 are parallel to the two slide rails 14, and the other ends of the two engaging springs 243 abut against the clamping block 242, so that the two engaging springs 243 jointly push the clamping block 242 away from the end of the sleeve rod 21 extending from the frame 10, thereby allowing the middle portion of the clamping block 242 to be disengaged from the engaging state with one end of the sleeve rod 21. The end of the block 242 facing away from the latching spring 243 is provided with a top portion. A sensing slot 15 is provided on the side of the frame 10 facing the top portion. The side of the sensing slot 15 facing the top portion is open, allowing the top portion to slide into the sensing slot 15, with the sensing bead 241 positioned within the sensing slot 15. Furthermore, one end of the sensing bead 241 abuts the inner bottom wall of the sensing slot 15, while the other end of the sensing bead 241 pushes against the top portion of the block 242, engaging the block 242 with the sleeve rod 21 while also compressing the two latching springs 243, thereby preventing the sleeve rod 21 from sliding. The sensing bead 241 is a temperature sensing element, such as a temperature-sensing glass ball on a fire hose nozzle. When the sensing bead 241 ruptures due to heat, the two latching springs 243 push the block 242 away from the sleeve rod 21, disengaging the block 242 from the sleeve rod 21 and allowing the sleeve rod 21 to slide.

[0049] As shown in the figure, in one embodiment, the sleeve rod 21 includes a rod body 211, a column 212 and a downward pressure spring 213. The column 212 is set on the rod body 211, the column 212 passes through the frame 10 and is engaged with the block 242, and the downward pressure spring 213 is sleeved on the column 212, and the downward pressure spring 213 pushes the rod body 211 and the frame 10 respectively.

[0050] It should be noted that the rod body 211 is slidably set in the frame 10, and the column 212 is set on one end of the rod body 211, and the other end of the column 212 passes through the column hole on the frame 10, extends from the outer wall of one end of the frame 10 and is engaged with the block 242. A slot 2121 is provided on the column 212, and the slot 2121 is opened along the circumferential surface of the column 212, and the slot 2121 is located on the end of the column 212 extending from the frame 10, so that the block 242 can be engaged in the slot 2121. Furthermore, the diameter of the column 212 is smaller than the side length of the rod 211, allowing the downward pressure spring 213 to be sleeved on the column 212. When the column 212 extends from the column hole and engages with the block 242, the rod 211 and the frame 10 jointly compress the downward pressure spring 213. When the two engaging springs 243 jointly push the block 242 away from the slot 2121 on the column 212, the downward pressure spring 213 pushes the rod 211 downward. Furthermore, each inclined slot 2111 is formed on the rod 211, so that when the rod 211 slides downward, it drives each sleeve 221 on the conduit 22 to sleeve with one end of each T-block 2312, thereby connecting the conduit 22 with each nozzle 231.

[0051] like Figures 1 to 3 As shown, in one embodiment, the water spray assembly 20 also includes a cavity 25, a bracket 26 and a plug 27. One end of the cavity 25 is sleeved on the end of the conduit 22 away from the fan blade plate, and the other end of the cavity 25 is connected to the water pipe. The plug 27 is arranged on one end of the bracket 26, and the other end of the bracket 26 is arranged on the end of the conduit 22 away from the fan blade plate, and the interior of the bracket 26 is connected to the conduit 22, and the bracket 26 and the plug 27 are both located in the cavity 25.

[0052] It should be noted that lumen 25 is a hollow tube with one end having a raised screw threaded into it, which is connected to the water pipe. The other end of lumen 25 is sleeved onto the end of catheter 22 away from T-block 2312, allowing the end of catheter 22 away from T-block 2312 to slide into or out of lumen 25. Furthermore, the inner diameter of lumen 25 is greater than the outer diameter of catheter 22, and a gap is left between lumen 25 and catheter 22, with the end of catheter 22 away from T-block 2312 communicating with the gap. Bracket 26 is disposed on the end of catheter 22 away from T-block 2312, and plug 27 is disposed on the end of bracket 26 away from catheter 22, allowing the movement of catheter 22 to drive bracket 26 and plug 27 to slide within lumen 25. When the catheter 22 drives the plug 27 to slide closer to the end of the cavity 25 connected to the water pipe, the plug 27 closes the end of the cavity 25 connected to the water pipe, so that the water in the water pipe cannot enter the catheter 22. When the catheter 22 drives the plug 27 to slide away from the end of the cavity 25 connected to the water pipe, the other end of the catheter 22 is simultaneously connected to the T-block 2312. In this way, when the plug 27 opens the end of the cavity 25 connected to the water pipe, water can enter the catheter 22, flow from each T-block 2312 to each spray hole 231, and be sprayed out from each spray hole 231.

[0053] like Figures 6 to 8 As shown, in one embodiment, the bracket 26 includes a disc and a plurality of support bars 261, one end of each support bar 261 is arranged on the end of the duct 22 away from the fan blade, each support bar 261 is connected to the disc, and the plug 27 is arranged on a side surface of the disc away from each support bar 261.

[0054] It should be noted that each support bar 261 jointly supports the plug 27 to close one end of the cavity tube 25 connected to the water pipe, and the bracket 26 has a hollow structure, so that the catheter 22 can be connected to the gap, and the water in the water pipe can flow into the gap, and then pass through the bracket 26 and into the catheter 22.

[0055] like Figures 6 to 8 As shown, in one embodiment, a sealing groove 271 is formed on the plug 27, and the sealing groove 271 is used to install a sealing ring.

[0056] It should be noted that a sealing ring is mounted on the circumferential surface of the plug 27. The sealing ring is located within a sealing groove 271. This allows the plug 27 to seal the gap between the lumen 25 and the conduit 22 when it is near the end where the lumen 25 is connected to the water pipe, thereby preventing water from flowing into the conduit 22. Furthermore, a sealing groove 271 is also formed on the end where the lumen 25 is sleeved onto the conduit 22. A sealing ring is mounted within the sealing groove 271. When the conduit 22 drives the plug 27 away from the end where the lumen 25 is connected to the water pipe, the sealing ring seals the other end of the gap, thereby preventing water from flowing into the conduit 22 only through the bracket 26.

[0057] like Figure 1 、 Figures 9 and 10 As shown, in one embodiment, two frames 10 are provided, and the two frames 10 are connected by an axle rod, and the fan blade member 23 is rolled up onto the axle rod. Both ends of each fan blade plate are provided with a T-block 2312, and the T-blocks 2312 at both ends of the fan blade plate are slid on the frames 10 at both ends of the axle rod, and one end of the two T-blocks 2312 can be respectively connected to the sleeves 221 on the two conduits 22, and the other ends of the two T-blocks 2312 are connected to both ends of the fireproof plate 232, and the through holes 23121 in the two T-blocks 2312 are connected to the channels in the fireproof plate 232, so that the two through holes 23121 are connected to the nozzles 231 of the front leaf and the rear leaf.

[0058] It should be noted that, when there is no fire, one end of the induction bead 241 pushes the block 242 to make the block 242 clamp the column sleeve rod 21 extend out of one end of the frame 10, so that the sleeve rod 21 cannot slide downward, and at the same time, one end of the conduit 22 blocks the water pipe, and the other end of the conduit 22 is retracted into the frame 10 to disengage from the engagement with the T-shaped block 2312. At this time, the fan blade 23 can be rolled up onto the shaft and can also be unfolded from the shaft to form a door body. When a fire occurs, the induction bead 241 breaks, and the two clamping springs 243 jointly push the block 242 out of the slot 2121, and the sleeve rod 21 can quickly slide downward under the push of the downward pressure spring 213. The sleeve rod 21 moves, thereby causing the sleeve rod 21 to drive the conduit 22 to slide quickly from the first chamber to the second chamber, so that the sleeve heads 221 on the conduit 22 are simultaneously engaged with the T-blocks 2312 on the fan blade 23, and at the same time, the sleeve rod 21 drives the plug 27 provided on the conduit 22 away from the water pipe, thereby allowing water to begin to flow into the conduit 22. At this time, one end of the conduit 22 opens the water pipe, and at the same time, the other end of the conduit 22 completes the engagement with the fan blade 23. In this way, the water in the water pipe can follow the conduit 22 to leave the fan blade 23 and be sprayed out from the spray holes 231 on each fan blade plate to reduce the temperature of the fire shutter door 1, thereby improving the fire resistance of the fire shutter door 1.

[0059] It should be noted that when a fire occurs, if the fan member 23 is not deployed in time but is still in the retracted state, the fire can spread from the space within the fan member 23 to other locations, thereby expanding the scope of the fire. Furthermore, because the frame 10 is provided with a chute 13, one end of each T-block 2312 slides within the chute 13, and each T-block 2312 is engaged with each sleeve 221, when the fan member 23 is in the retracted state, each sleeve 221 is aligned with the chute 13. In this way, the water ejected from each sleeve 221 will pass through the chute 13 and spray into the space below the fan member 23. Furthermore, two frames 10 are provided, and two water spray assemblies 20 are also provided. The two water spray assemblies 20 are respectively arranged in the two frames 10, and the two water spray assemblies 20 can be connected with the T-blocks 2312 at both ends of the fan blade plate. When the fan blade 23 is in the reeled state, the sleeves 221 on the water spray assemblies 20 on the two frames 10 spray water from the two chutes 13 to the space area below the fan blade 23 to form a continuously spraying water curtain door, thereby isolating the spread of fire, thereby improving the fire prevention effect of the fireproof rolling shutter door 1 of the present application.

[0060] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
