Description

Technical Field

[0001] The invention relates to the technical field of fire-resistant windows, in particular to a heat-insulating aluminum alloy fire-resistant window with a reinforced structure. Background Art

[0002] There are various kinds of aluminum alloy fire-resistant windows on the market today. The materials of the fire-resistant windows themselves are fireproof. When a fire occurs indoors, the fire-resistant windows are closed and the air between indoor and outdoor areas does not circulate. In this way, the fire cannot spread quickly due to poor ventilation, and may even be automatically extinguished due to lack of oxygen. Usually, the fire-resistant windows may be opened due to indoor ventilation needs. In this way, once a fire occurs, the fire-resistant windows in the open state cannot prevent the spread of the fire. With the gradual popularization of smart home life, fire-resistant windows that can be automatically controlled to open and close are put into use. When a fire occurs, the fire-resistant windows are closed by remote control. The disadvantage is that electronic instruments need to be arranged on the fire-resistant windows. The high temperature of the fire may burn the electronic instruments or destroy the remote control system.

[0031] refer to Figure 6 It is understood that the pressing part 5 includes an inner seat 16, an inner shaft 17, a pressure feeding rack 18 and a direction plate 19. The inner shaft 17 is movably sleeved in a through hole opened on the inner seat 16. One end of the inner shaft 17 is transmission-connected with the power tool 9, and the other end of the inner shaft 17 is transmission-connected with the pressure feeding rack 18 through a fixed column gear. The direction plate 19 slides through the plate hole opened on the pressure feeding rack 18, and one end of the direction plate 19 is fixed on the day window frame 1. The pressure feeding rack 18 supports the concave folding plate frame 11 through contact transmission. Figure 6 The figure shows a situation where no fire has occurred. At this time, the movable window 2 is open, and the concave folding plate frame 11 is driven to slide to the left through the transmission. After the concave folding plate frame 11 slides to the left to the end, it just contacts the right end of the pressure rack 18. No contact will not affect the subsequent push. Once a fire occurs, the power device 9 drives the inner shaft 17 to rotate, and then drives the pressure rack 18 to slide to the right. The pressure rack 18 pushes the concave folding plate frame 11. The concave folding plate frame 11 slides to the right and drives the arc-shaped rack 12 to reset, and then drives the movable window 2 to reset and swing through the support seat 13. Finally, the movable window 2 automatically closes on the day window frame 1. In this way, when a fire occurs, the fire-resistant window will seal the indoor and outdoor to prevent the fire from contacting the external environment and expanding.

[0032] refer to Figure 7 It is understood that the detection device 7 includes a smoke passing unit 20, a smoke exhaust box 21 and an inclined door panel 22. The smoke exhaust box 21 is a long groove shell. The smoke exhaust box 21 passes through the concave folding panel 6. The smoke exhaust box 21 is provided with an inclined door panel 22 for controlling the partition. One end of the inclined door panel 22 is hinged to the smoke exhaust box 21. One side of the smoke exhaust box 21 is connected to a row of smoke passing units 20.

[0033] refer to Figure 7It is understood that the smoke passing unit 20 is distributed in the concave groove of the day window frame 1, and the smoke passing unit 20 includes a cylindrical box 23, a neck tube 24, a hard plastic column 25, a follower block 26, an outer fixed column 27 and a spring 28. One end of the neck tube 24 is fixedly connected to the smoke exhaust box 21, and the other end of the neck tube 24 passes through one side shell of the cylindrical box 23, and an air inlet hole is opened on the other side shell of the cylindrical box 23. A hard plastic column 25 and a spring 28 are movably arranged in the cylindrical box 23, one end of the outer fixed column 27 is fixed on the cylindrical box 23, and the other end is fixed on the concave panel 6, a follower block 26 is fixed on the hard plastic column 25, and the follower block 26 is in contact with the horizontal long plate 8.

[0034] The hard plastic column 25 includes a thin rod and a thick rod fixed at both ends of the thin rod, and the thin rod is distributed between the neck tube 24 and the air inlet hole on the cylindrical box 23. The spring 28 is supported between the hard plastic column 25 and the bottom plate on the cylindrical box 23. The cylindrical box 23 is provided with a plate hole for the follower block 26 to slide.

[0035] refer to Fig. 9 It is understood that the power tool 9 includes a power head 30, a bracket 32, a worm 33 and a double-control shaft 35. One end of the double-control shaft 35 is clamped with a boss arranged on the upper end of the inner shaft 17 through a groove, and the other end of the double-control shaft 35 is connected by a fixed gear and a helical tooth meshing transmission on the worm 33. One end of the bracket 32 ​​is fixed on the horizontal long plate 8, and the other end is clamped into a plate groove opened on the worm 33. The worm 33 and the power head 30 are connected by transmission.

[0036] The power tool 9 also includes an adjustment group 34, a knife plate 29 and an inner frame 31. The knife plate 29 is distributed on the outside of the day window frame 1. One end of the knife plate 29 is positioned with the power head 30, and the other end is hinged to the folding plate fixed on the day window frame 1. The horizontal long plate 8 slides through the plate hole opened on the inner frame 31 through the fixed square plate. The adjustment group 34 supports the limiting double control shaft 35, and the worm 33 is movably sleeved in the through hole opened on the inner frame 31. The inner frame 31 is fixed on the day window frame 1.

[0037] refer to Fig. 9It is understood that the adjustment group 34 includes a first square tube 36, an L-shaped control plate 37 and a return spring 38. The first square tube 36 passes through the partial shell of the day window frame 1, and the L-shaped control plate 37 slides through the first square tube 36. One end of the L-shaped control plate 37 extends to the outside of the day window frame 1. The double control shaft 35 is movably sleeved in the through hole opened at the other end of the L-shaped control plate 37. One end of the return spring 38 is fixed on the first square tube 36, and the other end is fixed on the L-shaped control plate 37. The design of the adjustment group 34 can be used to disconnect the transmission between the double control shaft 35 and the inner shaft 17. That is, the worker pulls the L-shaped control plate 37 upward from the outside, and the L-shaped control plate 37 drives the double control shaft 35. The double control shaft 35 moves axially and rises, and naturally separates from the inner shaft 17. Because the fire-resistant window needs to be opened again after the fire is over, due to the control of the transmission path, the movable window 2 cannot be forcibly opened. Therefore, after the transmission path is interrupted, the double control shaft 35 and the inner shaft 17 are separated, and the movable window 2 can be directly opened.

[0038] refer to Fig.10 It is understood that the power head 30 includes a power cylinder 39, a spring 40 and an external control shaft 41. The external control shaft 41 is movably sleeved in a through hole opened on the day window frame 1. The spring 40 is fixedly sleeved on one end of the external control shaft 41, and the power cylinder 39 is fixedly sleeved on the outside of the spring 40. The other end of the external control shaft 41 is clamped with the blade 29 through a groove. The power cylinder 39 includes a cylinder body and an annular cylinder gear fixed at one end of the cylinder body. An annular groove is opened on the outer wall of the cylinder body of the power cylinder 39, and the inner frame 31 is fixed by a groove. Two symmetrically distributed arc plates are used to clamp the annular groove of the limiting power cylinder 39. The worm 33 is connected to the power cylinder 39 through a fixed gear meshing transmission. Before the fire-resistant window is put into use, the heating will push the knife plate 29 away from the external control shaft 41, and then the external control shaft 41 will be rotated, so that the mainspring 40 will be tightened and stored. After the power is fully stored, the knife plate 29 will be closed again. In this way, once the worm 33 can rotate, the mainspring 40 releases the power to drive the power cylinder 39 to rotate, and the power cylinder 39 drives the worm 33 to rotate.

[0039] When the movable window 2 is closed on the day window frame 1, the indoor and outdoor are separated, and if a fire occurs, the fire will not spread further through the fire-resistant window. Normally, the movable window 2 on the fire-resistant window is open, which is conducive to ventilation between the indoor and outdoor. However, once a fire occurs, the wind will help the fire, and failure to close the movable window 2 in time will cause the fire to spread. Therefore, the fire-resistant window of the present invention has the function of autonomously detecting fire and automatically closing the window. Specifically, when a fire occurs when the movable window 2 is open, indoor smoke will be discharged through the opened movable window 2. When the smoke is thick, the smoke will also enter the concave groove of the day window frame 1 through the smoke exhaust hole 10, and then be discharged through the detection device 7, thereby automatically triggering the adjustment control. Specifically, the hot smoke is injected into the cylindrical box 23, and then injected into the smoke exhaust box 21 through the neck tube 24. The smoke flow blows the inclined door panel 22 and is then discharged to the outside. The hard plastic column 25 will be melted during the flow of hot smoke, and then the spring 28 rebounds and pushes Figure 7The bottom of the hard plastic column 25 rises, and the rising part of the hard plastic column 25 drives the follower block 26, and the follower block 26 rises to push the horizontal long plate 8, and then Fig. 9 The horizontal long plate 8 in the middle rises and drives the bracket 32, and one end of the bracket 32 ​​is pulled out from the worm 33, so that the worm 33 that loses its position quickly rotates multiple circles under the drive of the power head 30, and the worm 33 drives the double-control shaft 35, thereby driving the inner shaft 17 to rotate. As mentioned earlier, the rotation of the inner shaft 17 will cause the pressure rack 18 to push the concave folding plate frame 11, and finally the movable window 2 is closed on the day window frame 1.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
