[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] like Figure 1 , Figure 2 , Figure 3 As shown, a fireproof window with fire extinguishing function includes a window frame 1, a window sash 2, a mounting box 3, a spray bar 4, a sealing plate 5, a switching mechanism 6, and a locking mechanism 7.

[0019] like Figure 1 , Figure 2 , Figure 3As shown, the window frame 1 is rectangularly mounted on the wall, the window sash 2 is mounted on the window frame 1, and the mounting box 3 is horizontally mounted at the bottom of the outer side of the window frame 1, with a long, narrow through hole 31 horizontally positioned on its surface. The spray bar 4 is horizontally mounted inside the mounting box 3 and is used to slide through the through hole 31. A sealing plate 5 is located at the front end of the spray bar 4 and is used to seal the through hole 31. Multiple nozzles 41 are spaced apart on the lower end face of the spray bar 4, and a spring 42 is installed between the back side and the mounting box 3.

[0020] like Figure 1 , Figure 2 , Figure 3 As shown, the switch mechanism 6 is located inside the mounting box 3 and is used to control the opening and closing of the spray bar 4. The switch mechanism 6 includes a fixed tube 61, a sliding tube 62, and a water inlet pipe 63. The fixed tube 61 is horizontally located inside the mounting box 3, and the sliding tube 62 is horizontally slidably connected to the outer wall of the fixed tube 61 and communicates with the spray bar 4. The water inlet pipe 63 is located at the tail end of the sliding tube 62 and is used to communicate with the sliding tube 62 after sliding.

[0021] like Figure 1 , Figure 2 , Figure 4 As shown, the locking mechanism 7 is located on the outside of the mounting box 3 and is used to fix the sealing plate 5. The locking mechanism 7 includes a locking tube 71, a locking plate 72, a tension spring 73, a pull rod 74, and a pull rope 75.

[0022] like Figure 1 , Figure 2 , Figure 4 As shown, locking tubes 71 are located at both ends of the mounting box 3 with their openings facing each other. Locking plate 72 is horizontally slidably connected to locking tube 71 and is used to press against the outer wall of sealing plate 5. Tension spring 73 is located between the inner side of locking tube 71 and locking plate 72. Pull rod 74 is located on locking plate 72 and passes through locking tube 71. Pull rope 75 is located between a pair of pull rods 74.

[0023] like Figure 4 As shown, the pull rope 75 includes a fiber rope 76 and an end 77. The end 77 is located at both ends of the fiber rope 76. The pull rod 74 is provided with a through hole 78 for the end 77 to pass through. The end 77 is provided with a plurality of retaining rings 79 at intervals for pressing the outer wall of the pull rod 74.

[0024] When the fireproof window is installed, the spray bar 4 retracts into the mounting box 3, and the sealing plate 5 blocks the through hole 31. At this time, the sliding tube 62 on the spray bar 4 is completely sleeved on the fixed tube 61, and the fixed tube 61 blocks the opening of the water inlet pipe 63, so that the water inlet pipe 63 can always be supplied with water and there will be no water leakage.

[0025] At the same time, pulling a pair of levers 74 brings them closer together, causing the levers 74 to slide the locking plate 72 outward and press the sealing plate 5, thus securing the sealing plate 5. Then, the pull rope 75 is removed, and the ends 77 of the pull rope 75 are threaded through the locking holes 78 on the levers 74. Suitable retaining rings 79 are selected on the ends 77 to tighten the pull rope 75, causing the pair of locking plates 72 to press the sealing plate 5, thus securing the sealing plate 5 and the spray bar 4.

[0026] In the event of a fire, the flames will spread upwards from the windows of the lower floors. When the flames come into contact with the fiber rope 76, the fiber rope 76 will be automatically burned off. At this time, under the tension of the tension spring 73, the locking plate 72 will retract into the locking tube 71, thereby releasing the locking of the sealing plate 5.

[0027] At the same time, under the elastic force of the spring 42, the spray bar 4 and the sealing plate 5 will be pushed to slide outward. The spray bar 4 drives the sliding tube 62 and the water inlet pipe 63 to move synchronously until the end of the spray bar 4 is outside the mounting box 3. Then the water inlet pipe 63 is separated from the fixed pipe 61, so that the water source in the water inlet pipe 63 can enter the sliding tube 62 and the spray bar 4, and spray out along the nozzle 41 to achieve fire extinguishing by spraying at the window position of the lower floor.

[0028] Therefore, by installing fireproof windows with sprinkler fire suppression functions, when a fire breaks out in the lower floor, the fire can be extinguished by spraying the windows of the lower floor with the spray boom 4, preventing the flames from spreading to the upper floors, improving the fire prevention effect, and ensuring the safety of people's property and lives.

[0029] In the event of a fire, the flames burning in the lower floors can be used to control the sliding and opening / closing of the spray boom 4, thereby enabling automatic sprinkler fire suppression without manual control, thus achieving timely fire extinguishing.

[0030] like Figure 3 As shown, the lower end of the sealing plate 5 is provided with a groove 51, and a roller 52 is rotatably connected in the groove 51. A fireproof net 53 is provided on the roller 52, and a counterweight rod 54 is provided at the lower end of the fireproof net 53.

[0031] When the spray bar 4 is used to spray fire extinguishing agents at the windows of the lower floor, the sealing plate 5 automatically slides outward, and the groove 51 is exposed outside the mounting box 3. Under the gravity of the counterweight rod 54, the fireproof net 53 automatically unrolls and covers the windows of the lower floor, thereby blocking the flames, further preventing the spread of the flames, improving the fire prevention effect, and ensuring the safety of people's property and lives.

[0032] like Figure 5 , Figure 6As shown, a pair of suction cups 32 are provided on the back side of the mounting box 3. A sealing gasket 33 is embedded in the outer edge of the suction cup 32 to increase the sealing of the opening. An adhesive gasket 34 is provided on the suction cup 32 to surround the sealing gasket 33 for bonding and fixing, and to increase stability.

[0033] like Figure 5 , Figure 6 As shown, a negative pressure mechanism 8 is provided between a pair of suction cups 32. The negative pressure mechanism 8 includes a negative pressure tube 81, a piston 82, a rotating shaft 83, a gear 84, a rack 85, a handwheel 86, and a ratchet 87.

[0034] like Figure 5 , Figure 6 As shown, the negative pressure pipe 81 is horizontally connected to a pair of suction cups 32, the piston 82 is slidably connected to the negative pressure pipe 81, the rotating shaft 83 is vertically rotatably connected to the negative pressure pipe 81, the gear 84 is set at the inner end of the rotating shaft 83, and the rack 85 is set on the back side of the pair of pistons 82 and meshes with the gear 84.

[0035] like Figure 5 , Figure 6 As shown, the handwheel 86 is located at the outer end of the rotating shaft 83, and the ratchet teeth 87 are located between the rotating shaft 83 and the outer wall of the negative pressure pipe 81 to restrict the handwheel 86 to rotate only in one direction, and to achieve automatic fixation after rotation.

[0036] When fixing the mounting box 3, place the mounting box 3 at the window position, and then make the pair of suction cups 32 on the back side abut against the outer wall of the window frame 1. At this time, the mounting box 3 is bonded and initially fixed by the adhesive pad 34.

[0037] Then, the handwheel 86 drives the rotating shaft 83 to rotate, which in turn drives the gear 84 to rotate synchronously. The gear 84 drives a pair of racks 85 to slide relative to each other, pulling a pair of pistons 82 closer together. At this time, a negative pressure is generated between the negative pressure tube 81 and the suction cup 32, causing the suction cup 32 to be firmly attached to the window frame 1. At the same time, the locking action of the ratchet teeth 87 can fix the pistons 82, thereby firmly fixing the mounting box 3 to the window frame 1.

[0038] Therefore, by setting up the installation box 3 for drilling-free installation and fixing, the installation box 3 can be quickly installed and fixed. At the same time, it can be adapted to fireproof windows with different location requirements, and fireproof windows can be modified and installed at will, improving practicality.

[0039] The specific embodiments are merely illustrative of the present invention and are not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
