Description

Technical Field

[0001] The present application relates to the field of fireproof windows, and in particular to a fireproof aluminum alloy window. Background Art

[0002] Fire-resistant windows are windows that, along with their frames, meet fire resistance stability and integrity requirements for a specified period of time. Fire-resistant windows should be used where light and ventilation are required between the exterior walls of two buildings with insufficient fire separation, or between spaces separated by fire walls. The performance of fire-resistant windows depends on both the glass and the frame; failure of either component renders the fire-resistant window ineffective. Therefore, fire-resistant windows must undergo reliable testing and verification.

[0003] Fireproof windows generally include fixed fireproof windows and movable fireproof windows. Fixed fireproof windows have no openable sashes, which can provide light and shelter from wind and rain under normal circumstances, and can prevent the spread of fire in the event of a fire; movable fireproof windows are equipped with sash opening and closing control devices, which can be opened and closed. In the event of a fire, they can automatically close to prevent the spread of fire, and can be opened to exhaust smoke, and can provide light and ventilation under normal circumstances.

[0004] Among them, fixed fireproof windows are generally installed on the exterior walls. Although they are relatively fireproof, they cannot be disassembled after installation. Therefore, their maintenance is relatively difficult compared to movable fireproof windows. The most common problem is that the dust on the outer surface is difficult to clean, resulting in the light transmittance gradually decreasing over time, affecting their daily use.

[0005] Therefore, there is an urgent need to provide a fixed fireproof window that can meet the user's daily cleaning needs while ensuring its fireproof performance. Summary of the Invention

[0006] In order to meet the needs of users for convenient daily cleaning while ensuring the fireproof performance of fireproof windows, the present application provides a fireproof aluminum alloy window.

[0007] The present application provides a fireproof aluminum alloy window, which adopts the following technical solution:

[0008] A fireproof aluminum alloy window, comprising:

[0009] The outer frame includes an external connection portion that can be fixed to the wall mounting groove and an external retaining portion that is arranged on the inner side of the external connection portion away from the indoor side;

[0010] An inner frame is embedded with a fireproof glass plate, the outer peripheral wall of the outer frame can abut against the inner peripheral wall of the external connection portion; and the outer side of the inner frame can abut against the inner side of the external blocking portion;

[0011] A guard plate is arranged on the side of the outer frame close to the indoor environment. The guard plate can abut the inner side of the inner frame and the inner side of the external connection part of the outer frame. A first plug ring is formed on the inner side of the guard plate, and a first slot is formed at the position of the outer frame corresponding to the first plug ring. Two first elastic plates that can be inserted into or out of the first slot as they are deformed under pressure are fixed to the end of the first plug ring. A first thermal expansion seal that can prevent the first elastic plate from being out of the first slot after thermal expansion is provided between the two first elastic plates.

[0012] By adopting the above technical solution, when installing the fireproof window, the outer frame is fixed to the installation groove of the wall through the outer peripheral surface of its external connection part, and then the inner frame with the fireproof glass plate embedded therein is placed in the external connection part of the outer frame, so that the outer peripheral wall of the inner frame abuts against the inner peripheral wall of the external connection part of the outer frame, and the outer side of the inner frame abuts against the inner side of the outer stop part of the outer frame, and then the guard plate is placed inside the external connection part of the outer frame. At this time, the two first elastic plates at the end of the first inserting ring are squeezed to insert the first inserting ring into the first slot of the outer frame, so that the guard plate can be fixed to the inner side of the external connection part of the outer frame. Thereby, the inner frame is also fixed. When it needs to be disassembled, the guard plate is pushed away from the outer frame with force, so that the first elastic plate of the first plug ring can be deformed again until it is separated from the first slot of the outer frame. Then the inner frame with the fireproof glass plate embedded in it can be removed and cleaned. When a fire occurs, the first thermal expansion seal in the first elastic plate at the end of the first plug ring expands, which will prop up the two first elastic plates, thereby preventing the two first elastic plates of the first plug ring from being separated from the first slot, so that the guard plate is firmly fixed to the inner side of the outer frame, thereby ensuring the fireproof performance of the fireproof window.

[0013] Optionally, a positioning ring is formed on the outer side of the inner frame;

[0014] The outer retaining portion of the outer frame is formed with a positioning groove for inserting the positioning ring;

[0015] A thermal expansion ring is fixed to the outer end of the positioning ring and is used to restrict the positioning ring from being separated from the positioning groove after it expands due to heat.

[0016] By adopting the above technical solution, when installing the inner frame, the positioning ring can facilitate the positioning of the inner frame in the outer frame, and when a fire occurs, heat is transferred to the thermal expansion ring. On the one hand, the thermal expansion ring expands to prevent the positioning ring from detaching from the outer frame, and on the other hand, it can improve the sealing between the outer frame and the inner frame, avoid the entry of air, and prevent the fire from increasing.

[0017] Optionally, a second insert ring is formed on the inner side of the inner frame;

[0018] The guard plate is formed with a second slot with an inner size larger than that of the inlet portion for inserting the second insert ring;

[0019] Two second elastic plates are fixed to the end of the second insert ring and can be inserted into or removed from the second slot as they are deformed under pressure. Second thermal expansion seals are provided in the two second elastic plates and can prevent the two second elastic plates from leaving the second slot after thermal expansion.

[0020] By adopting the above technical solution, a second plug ring with a second elastic plate is used to cooperate with the second slot of the guard plate, which can further improve the stable connection between the guard plate and the inner frame. When a fire occurs, the second thermal expansion seal expands to prevent the two second elastic plates from detaching from the second slot, which can further improve the stable connection between the guard plate and the inner frame.

[0021] Optionally, a scroll is rotatably provided in the upper external portion of the outer frame along its length direction;

[0022] The reel is wound with a protective net whose lower side extends out of the lower side of the external connection portion above the outer frame;

[0023] A first magnetic strip is fixed to the lower side of the protective net;

[0024] A second magnetic strip is fixed to the upper side of the lower external connection portion of the outer frame along its length direction, and is used for adsorption with the first magnetic strip.

[0025] By adopting the above technical solution, when dismantling the inner frame, the protective net can be lowered by rotating the rotating shaft, and the first magnetic strip on the lower side of the protective net can be adsorbed with the second strip on the lower external part of the outer frame to fix the protective net, so as to partially protect the inner frame of the fire window when it is dismantled, and prevent foreign objects from entering the room.

[0026] Optionally, a first bevel gear is coaxially fixed to one end of the reel;

[0027] The outer portion of the outer frame is rotatably provided with a second bevel gear meshing with the first bevel gear;

[0028] A sliding shaft is provided in the external connection portion of the outer frame in a direction perpendicular to the first scroll axis, and the sliding shaft is coaxially inserted into the second bevel gear and can drive the second bevel gear to rotate synchronously;

[0029] A blocking structure capable of limiting the rotation of the sliding shaft is also provided in the external connection portion of the outer frame.

[0030] By adopting the above technical solution, the sliding shaft is rotated, and the first bevel gear and the second bevel gear are rotated to drive the reel to rotate forward and reverse, thereby realizing the winding and unwinding of the protective net, and the setting of the blocking structure can prevent the rotation of the reel. In this way, after the inner frame is installed, the sliding shaft can be rotated to drive the reel to rotate to realize the winding of the protective net, and the reel can be restricted by the blocking structure, thereby maintaining the wound state of the protective net to prevent the protective net from blocking the sunlight.

[0031] Optionally, the blocking structure includes:

[0032] A fixed sleeve is sleeved on the outside of the sliding shaft and fixed inside the outer frame, and a spline groove is formed in the fixed sleeve;

[0033] A spline column is coaxially fixed to the sliding shaft, and the spline column slides with the sliding shaft and can be inserted into the spline groove to limit the rotation of the sliding shaft;

[0034] The elastic member is fixed in the outer frame and is used for pushing the sliding shaft to slide to the spline column and be inserted into the spline groove.

[0035] By adopting the above technical solution, when the sliding shaft needs to be rotated, the sliding shaft is pushed to make the spline column of the sliding shaft disengage from the spline groove of the fixed sleeve, and then the sliding shaft is rotated to drive the reel to rotate. When the rotation of the sliding shaft needs to be stopped, the sliding shaft is dragged in the opposite direction to insert the spline column into the spline groove, thereby limiting the rotation of the sliding shaft. In addition, through the action of the elastic member, the spline column can be kept inserted in the spline groove, thereby ensuring the stability of the sliding shaft in the spline groove.

[0036] Optionally, the protective net is a steel net;

[0037] A thermal fuse is fixed between the reel and the first bevel gear. After the thermal fuse is blown, the protective net is unwound to be adsorbed by the first magnetic strip and the second magnetic strip.

[0038] A one-way thermal expansion bending plate is fixed to the lower outer barrier portion of the outer frame. The melting temperature of the heated fuse is lower than the thermal bending temperature of the one-way thermal expansion bending plate. After being heated, the one-way thermal expansion bending plate can bend toward the inner frame to limit the rise of the first magnetic strip.

[0039] By adopting the above technical solution, when a fire occurs, the heated fuse will melt first. At this time, the protective net will automatically fall down and be adsorbed by the first magnetic strip and the second magnetic strip. Then, as the temperature continues to increase, the unidirectional thermal expansion bending plate will bend in the direction of the first magnetic strip, thereby limiting the rise of the first magnetic strip, that is, keeping the protective net outside the glass plate of the inner frame. As the fire continues to develop, when the fireproof glass plate bursts, the protective net can limit the bursting direction of the fireproof glass plate, thereby preventing a large number of fireproof glass plates from falling outside the wall, reducing safety hazards to pedestrians outside, and improving safety.

[0040] Optionally, a coil spring is fixed on the reel, and the coil spring is wound as the protective net is wound, and after the reel is separated from the first bevel gear, the coil spring can drive the reel to unwind.

[0041] By adopting the above technical solution, when the heated fuse melts, the coil spring can push the reel to unwind immediately, thereby achieving the rapid drop of the protective net.

[0042] Optionally, a rotation groove is formed on one end of the sliding shaft away from the second bevel gear and extends to the inner side of the external connection portion of the outer frame.

[0043] By adopting the above technical solution, after opening the guard plate, the operator can drive the sliding shaft to rotate through external tools.

[0044] Optionally, the outer frame is provided with sliding grooves in the vertical direction at positions corresponding to both ends of the first magnetic strip, and both ends of the first magnetic strip slide in the sliding grooves.

[0045] By adopting the above technical solution, the reeling or unreeling trajectory of the protective net can be restricted when the protective net is extended or reeled.

[0046] In summary, this application includes at least one of the following beneficial technical effects:

[0047] 1. When installing a fireproof window, the outer frame is fixed to the mounting groove of the wall through the outer peripheral surface of its external connection part, and then the inner frame with the fireproof glass plate embedded therein is placed in the external connection part of the outer frame, so that the outer peripheral wall of the inner frame abuts against the inner peripheral wall of the external connection part of the outer frame, and the outer side of the inner frame abuts against the inner side of the outer stop part of the outer frame, and then the guard plate is placed inside the external connection part of the outer frame. At this time, squeeze the two first elastic plates at the end of the first inserting ring so that the first inserting ring is inserted into the first slot of the outer frame, so that the guard plate can be fixed to the inner side of the external connection part of the outer frame, thereby also The inner frame is fixed. When it needs to be disassembled, the guard plate is pushed away from the outer frame with force, so that the first elastic plate of the first plug ring can be deformed again to be separated from the first slot of the outer frame. Then the inner frame with the fireproof glass plate embedded in it can be removed and cleaned. When a fire occurs, the first thermal expansion seal in the first elastic plate at the end of the first plug ring expands, which will prop up the two first elastic plates, thereby preventing the two first elastic plates of the first plug ring from being separated from the first slot, so that the guard plate is firmly fixed to the inner side of the outer frame, thereby ensuring the fireproof performance of the fireproof window.

[0048] 2. When installing the inner frame, the positioning ring can facilitate the positioning of the inner frame in the outer frame. When a fire occurs, heat is transferred to the thermal expansion ring. On the one hand, the thermal expansion ring expands to prevent the positioning ring from detaching from the outer frame. On the other hand, it can improve the sealing between the outer frame and the inner frame, avoid the entry of air, and prevent the fire from increasing. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] The present application discloses a fireproof aluminum alloy window, which is mainly used to solve the problem that traditional fixed fireproof windows are difficult to clean due to dust on the outer surface, resulting in the light transmittance gradually decreasing over time, affecting their daily use.

[0060] To this end, the main idea adopted in this application is to divide the fixed fireproof window into an outer frame for fixing in a wall mounting groove, an inner frame with a fireproof glass panel embedded therein and which can be placed inside the outer frame, and a guard plate that can further connect the outer frame and the inner frame. During normal use, the guard plate and the outer frame fix the inner frame with the fireproof glass panel embedded therein. When the fireproof glass panel needs to be cleaned, the guard plate is removed, the inner frame is disassembled from the outer frame, the glass panel is cleaned, and the inner frame is installed in the outer frame and the guard plate is fixed.

[0061] In this way, while ensuring the fire resistance of the fire window, the problem that the light transmittance of the traditional fixed fire window gradually decays over time due to the difficulty of cleaning the dust on the outer surface, affecting its daily use, is solved.

[0062] The following will further elaborate on this application with reference to the attached Figure 1-9 drawings.

[0063] Example 1,

[0064] Refer to Figure 1 , a fireproof aluminum alloy window, including an outer frame 1 made of aluminum alloy, an inner frame 2, and a protective plate 3.

[0065] Refer to Figure 1 and Figure 2 , the cross-section of the outer frame 1 is in an "L" shape, including an integrally formed outer connection part 11 and an outer blocking part 12. The outer peripheral surface of the outer connection part 11 is fixed to the groove wall of the installation groove of the wall. In this way, the fixation of the outer frame 1 on the wall is achieved. The outer blocking part 12 is arranged on the inner peripheral surface of the outer connection part 11, and when assuming one side of the wall is the indoor side and the other side is the outdoor side, the outer blocking part 12 is located on the side of the outer connection part 11 away from the indoor side.

[0066] Refer to Figure 2 and Figure 3 , the cross-section of the inner frame 2 is in a "U" shape, and a fireproof glass plate 4 is embedded in the inner frame 2. The inner frame 2 can be inserted into the outer frame 1. After the inner frame 2 is inserted into the outer frame 1, the outer peripheral surface of the inner frame 2 can abut against the inner peripheral surface of the outer connection part 11 of the outer frame 1, and the side of the inner frame 2 away from the indoor side can abut against the side of the outer blocking part 12 of the outer frame 1 close to the indoor side. The side of the inner frame 2 close to the indoor side is flush with the side of the outer connection part 11 of the outer frame 1 close to the indoor side.

[0067] Refer to Figure 2 and Figure 3 , a "mouth" - shaped positioning ring 21 is convexly formed on the side of the inner frame 2 away from the indoor side, and a positioning groove 121 is formed at the position of the outer blocking part 12 of the outer frame 1 corresponding to the positioning ring 21. When the inner frame 2 is inserted into the outer frame 1, the positioning ring 21 can be inserted into the positioning groove 121. A thermal expansion ring 211 is also fixed to the outer end of the positioning ring 21. When a fire occurs, heat is transferred to the thermal expansion ring 211, and the thermal expansion ring 211 expands. On the one hand, it prevents the positioning ring 21 from detaching from the outer frame 1, and on the other hand, it can improve the sealing performance between the outer frame 1 and the inner frame 2, avoiding the entry of air and preventing the spread of fire.

[0068] Refer to Figure 4The guard plate 3 is arranged on the inner side of the outer blocking portion 12 of the outer frame 1 and the inner side of the inner frame 2. The guard plate 3 is protruded with a first plug ring 31 at the position corresponding to the external connection portion 11 of the outer frame 1. The external connection portion 11 of the outer frame 1 is formed with a first slot 111 at the position corresponding to the first plug ring 31. When the guard plate 3 is placed on the inner side of the outer frame 1 and the inner frame 2, the first plug ring 31 of the guard plate 3 can be inserted into the first slot 111 of the outer frame 1. The outer end of the first plug ring 31 is formed with two arc-shaped first elastic plates 311 with two arc openings arranged opposite to each other around the first plug ring 31. The first elastic plate 311 is also in the shape of a "mouth", and notches are formed at each corner position of the first elastic plate 311 to ensure the deformation ability of the first elastic plate 311. As the two first elastic plates 311 are compressed and deformed, the first insert ring 31 can be inserted into or disengaged from the first slot 111, thereby achieving the connection between the guard plate 3 and the external connection part 11 of the outer frame 1, and then the inner frame 2 is fixed by clamping the outer blocking part 12 of the outer frame 1 and the guard plate 3.

[0069] Reference Figure 4 Furthermore, a first thermal expansion seal 312 is housed in the space formed on opposite sides of the arc openings of the two first elastic plates 311. The first thermal expansion seal 312 is annular and has a circular cross-section. A gap is formed between the peripheral wall of the first thermal expansion ring 211 and the arc openings of the two first elastic plates 311, allowing the first elastic plate 311 to deform. Furthermore, the diameter of the first thermal expansion ring 211 is greater than the distance between the open sides of the two first elastic plates 311. This ensures that the first thermal expansion ring 211 cannot escape from the two first elastic plates 311.

[0070] Reference Figure 4 When a fire occurs, the first thermal expansion seal 312 in the first elastic plate 311 at the end of the first insert ring 31 expands, which will prop up the two first elastic plates 311, thereby preventing the two first elastic plates 311 of the first insert ring 31 from detaching from the first slot 111, so that the guard plate 3 is firmly fixed to the inner side of the outer frame 1, ensuring the fireproof performance of the fireproof window.

[0071] Reference Figure 5, Further, on the inner side of the inner frame 2, that is, the side of the inner frame 2 close to the interior, a second insertion ring 22 in the shape of a "mouth" character is formed. At the position of the second insertion ring 22 on the guard plate 3, a second slot 32 is formed for the insertion of the second insertion ring 22. The internal dimension of the second slot 32 is larger than the dimension of its inlet part. At the end of the second insertion ring 22, two second elastic plates 221 with opposite arc-shaped openings are fixed. The second elastic plates 221 are also in the shape of a "mouth" character, and gaps are formed at each corner of the second elastic plates 221. With pressure, the two second elastic plates 221 can be inserted into or disengaged from the second slot 32. In this way, by using the second insertion ring 22 with two second elastic plates 221 in cooperation with the second slot 32 of the guard plate 3, on the one hand, it can further improve the stable connection between the guard plate 3 and the inner frame 2, and on the other hand, when disassembling the guard plate 3 from the outer frame 1, the inner frame 2 can be directly pulled out of the outer frame 1 through the guard plate 3, and the operation is simple.

[0072] Refer to Figure 5 , Further, a second thermal expansion seal 222 is stored in the space formed on the side of the second elastic plates 221 with opposite arc-shaped openings. The second thermal expansion seal 222 is annular, and the cross-section of the second thermal expansion seal 222 is circular. A gap for the deformation of the second elastic plates 221 is formed between the peripheral wall of the second thermal expansion ring 211 and the arc-shaped sides of the two second elastic plates 221, and the diameter of the second thermal expansion ring 211 is larger than the distance between the open sides of the two second elastic plates 221. This ensures that the second thermal expansion ring 211 cannot disengage from within the two second elastic plates 221.

[0073] Refer to Figure 5 , and when a fire occurs, the second thermal expansion seal 222 in the second elastic plates 221 at the end of the second insertion ring 22 expands, which will撑起 the two second elastic plates 221, thereby preventing the two second elastic plates 221 of the second insertion ring 22 from disengaging from the second slot, so that the guard plate 3 is firmly fixed to the inner side of the inner frame 2, ensuring the fire prevention performance of the fire window.

[0074] The implementation principle of a fireproof aluminum alloy window in an embodiment of this application is as follows:

[0075] When installing the fireproof window, the outer frame 1 is fixed to the mounting groove of the wall through the outer peripheral surface of its external connection part 11, and then the inner frame 2 with the fireproof glass plate 4 embedded therein is placed in the external connection part 11 of the outer frame 1. The positioning ring 21 can facilitate the positioning of the inner frame 2 in the outer frame 1, so that the outer peripheral wall of the inner frame 2 abuts against the inner peripheral wall of the external connection part 11 of the outer frame 1, and the outer side of the inner frame 2 abuts against the inner side of the outer stop part 12 of the outer frame 1, and then the guard plate 3 is placed inside the external connection part 11 of the outer frame 1, and then the first plug ring 31 corresponds to the first slot 111, the second plug ring 22 corresponds to the second slot 32, and the guard plate 3 is pushed. The two first elastic plates 311 at the end of the first plug ring 31 will The first plug ring 31 is deformed under pressure, so that the first slot 111 of the outer frame 1 is inserted. At the same time, the two second elastic plates 221 at the end of the second plug ring 22 are also deformed under pressure, so that the second plug ring 22 is inserted into the second slot 32, so that the guard plate 3 can be fixed to the outer frame 1 and the inner frame 2. When disassembly is required, the guard plate 3 is dragged away from the outer frame 1 with force, so that the first elastic plate 311 of the first plug ring 31 and the second elastic plate 221 of the second plug ring 22 are deformed again, so that the first plug plate can be disengaged from the first slot 111, and the second plug plate can be disengaged from the second slot 32, so that the guard plate 3 and the inner frame 2 with the fireproof glass plate 4 embedded therein can be removed for cleaning.

[0076] When a fire occurs, heat is transferred to the thermal expansion ring 211. On the one hand, the thermal expansion ring 211 expands to prevent the positioning ring 21 from detaching from the outer frame 1. On the other hand, it can improve the sealing between the outer frame 1 and the inner frame 2 to prevent the entry of air. The first thermal expansion seal 312 expands to support the two first elastic plates 311 to prevent them from deforming, thereby preventing the two first elastic plates 311 of the first plug-in ring 31 from detaching from the first slot 111. The second expansion seal expands to support the two second elastic plates 221 to prevent them from deforming, thereby preventing the two second elastic plates 221 of the second plug-in ring 22 from detaching from the second slot 32, thereby sealing and fixing the guard plate 3 to the inner side of the outer frame 1 and the inner frame 2, thereby ensuring the fireproof performance of the fireproof window.

[0077] In summary, it is achieved that on the basis of ensuring its fire-proof performance, it can meet the needs of users for daily cleaning.

[0078] Example 2,

[0079] A fireproof aluminum alloy window, which differs from Example 1 in that a protective net 5 is also provided. On the one hand, it is used to shield the installation part of the inner frame 2 to prevent foreign objects from entering the room when the inner frame 2 is removed. On the other hand, it is used to limit the bursting direction of the fireproof glass plate 4 when it bursts after a fire occurs, thereby reducing damage to surrounding external personnel or objects when the fireproof glass plate 4 bursts.

[0080] The following details:

[0081] Reference Figure 6 and Figure 7 A reel 6 is rotatably provided in the upper external connection portion 11 of the outer frame 1 along its length direction. The reel 6 is located above the outer stop portion 12 of the outer frame 1. A protective net 5 is wound on the reel 6 at a position corresponding to the outer stop portion 12 of the outer frame 1. The protective net 5 is made of steel mesh. A long groove 122 is formed on the upper side of the outer stop portion 12 of the outer frame 1 corresponding to the position of the protective net 5. The long groove 122 extends from the lower side of the protective net 5 and is fixed with a first magnetic strip 51. A second magnetic strip 123 is fixed along its length direction on the lower external connection portion 11 of the outer frame 1. When the reel 6 is unwound, the protective net 5 falls until the first magnetic strip 51 and the second magnetic strip 123 are adsorbed, and the protective net 5 can be unfolded, thereby protecting the outdoor side of the outer frame 1.

[0082] Reference Figure 6 and Figure 7 Furthermore, in order to limit the movement trajectory of the first magnetic strip 51, sliding grooves 124 are formed on the adjacent sides of the outer retaining portions 12 on both sides of the outer frame 1, and the two ends of the first magnetic strip 51 slide in the two sliding grooves 124 respectively, thereby ensuring the sliding stability of the first magnetic strip 51.

[0083] Reference Figure 6 and Figure 7 Furthermore, a one-way thermal expansion bending plate 125 is vertically formed on the side of the lower outer barrier portion 12 of the outer frame 1 corresponding to the second magnetic strip 123 facing away from the room. When the one-way thermal expansion bending plate 125 is heated, the one-way thermal expansion bending plate 125 can bend in the direction of the second magnetic strip 123, thereby pressing on the first magnetic strip 51 above the second magnetic strip 123, thereby limiting the first magnetic strip 51 from rising, ensuring the unfolded state of the protective net 5, and then, when the fireproof glass plate 4 bursts, it can effectively protect the outdoor side of the fireproof glass plate 4 and reduce damage to the outside world.

[0084] Reference Figure 8 and Figure 9 Furthermore, the external connection portion 11 of the outer frame 1 is provided with a sliding shaft 7. The sliding shaft 7 is arranged horizontally and the axis direction of the sliding shaft 7 is perpendicular to the axis direction of the reel 6. A first bevel gear 61 is coaxially fixed to the end of the reel 6 close to the sliding shaft 7. A second bevel gear 71 is coaxially provided to the end of the sliding shaft 7 close to the reel 6. The second bevel gear 71 is rotatably connected to the outer frame 1 and remains meshed with the first bevel gear 61. The second bevel gear 71 is sleeved on the sliding shaft 7 and is engaged by a sliding key, so that the sliding shaft 7 can drive the second bevel gear 71 to rotate synchronously, and the sliding shaft 7 can slide relative to the second bevel gear 71. A blocking structure for limiting the rotation of the sliding shaft 7 is also provided in the outer frame 1.

[0085] Reference Figure 8 and Figure 9A rotation groove 72 is formed on one end of the sliding shaft 7 facing the guard plate 3. The rotation groove 72 can be a flat slot, a cross slot, or other shape that matches a common screwdriver, and the end of the sliding shaft 7 with the rotation groove 72 corresponds to the position of the first slot 111 of the external connection part 11 of the outer frame 1.

[0086] Reference Figure 8 and Figure 9 After the guard plate 3 is removed, a screwdriver that is adapted to the rotating slot 72 is used to pass through the first slot 111 and adapt to the rotating shaft, and then the sliding shaft 7 is rotated. Through the rotation of the first bevel gear 61 and the second bevel gear 71, the reel 6 can be driven to rotate forward and reverse, thereby realizing the winding and unwinding of the protective net 5, and the setting of the blocking structure can prevent the rotation of the reel 6. In this way, after the inner frame 2 is installed, the sliding shaft 7 can be rotated to drive the reel 6 to rotate to realize the winding of the protective net 5, and the reel 6 is restricted by the blocking structure, thereby maintaining the winding state of the protective net 5 to prevent the protective net 5 from blocking the sunlight.

[0087] Reference Figure 8 and Figure 9 Specifically, the resistance structure includes a fixed sleeve 8 and a spline column 73. The fixed sleeve 8 is fixed inside the outer frame 1 and coaxially sleeved on the outer side of the sliding shaft 7. A spline groove 81 is formed in the fixed sleeve 8. The spline column 73 is coaxially fixed to the sliding shaft 7. As the sliding shaft 7 slides, the spline column 73 can be inserted into the spline groove 81, thereby limiting the rotation of the sliding shaft 7. An elastic member 74, such as a spring, is fixed to the end of the sliding shaft 7 near the second bevel gear 71 in the outer frame 1. The elastic member pushes the sliding shaft 7 to slide until the spline column 73 is inserted into the spline groove 81.

[0088] Reference Figure 8 and Figure 9 When the sliding shaft 7 needs to be rotated, the sliding shaft 7 is pushed so that the spline column 73 of the sliding shaft 7 disengages from the spline groove 81 of the fixing sleeve 8, and then the sliding shaft 7 is rotated to drive the reel 6 to rotate. When the rotation of the sliding shaft 7 needs to be stopped, the sliding shaft 7 is pushed by the elastic member 74 so that the spline column 73 is inserted into the spline groove 81, thereby limiting the rotation of the sliding shaft 7.

[0089] Reference Figure 8 and Figure 9 Furthermore, a heated fuse 62 is fixed between the reel 6 and the first bevel gear 61. The melting temperature of the heated fuse 62 is lower than the heated bending temperature of the one-way thermal expansion bending plate 125. A coil spring 63 is provided on the reel 6 corresponding to the position of the heated fuse 62 away from the first bevel gear 61. The coil spring 63 is fixed between the outer frame 1 and the reel 6. The coil spring 63 is wound as the protective net 5 is wound, and after the reel 6 is separated from the first bevel gear 61, the coil spring 63 can drive the reel 6 to unwind.

[0090] Reference Figure 8 and Figure 9In summary, when a fire occurs, the thermal fuse 62 will melt first. At this time, the protective net 5 will automatically fall down until the first magnetic strip 51 and the second magnetic strip 123 are adsorbed. Then, as the temperature continues to increase, the unidirectional thermal expansion bending plate 125 will bend toward the first magnetic strip 51, thereby limiting the rise of the first magnetic strip 51, that is, keeping the protective net 5 outside the glass plate of the inner frame 2. As the fire continues to develop, when the fireproof glass plate 4 bursts, the protective net 5 can limit the bursting direction of the fireproof glass plate 4, thereby preventing a large number of fireproof glass plates 4 from falling outside the wall, reducing safety hazards to pedestrians outside, and improving safety.

[0091] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
