Description

Technical Field

[0001] The invention relates to a hidden rescue window with a span-distance unlocking structure, belonging to the technical field of curtain wall rescue windows. Background Art

[0002] In the construction industry, curtain walls, as a common building envelope, are widely used in high-rise buildings. Curtain wall rescue windows are important safety features installed on curtain walls. They are primarily used in emergencies such as fires and earthquakes to provide escape routes for trapped personnel and facilitate access for external rescuers.

[0003] Currently, most traditional curtain wall rescue windows adopt a casement or sliding structure. Their locks are usually set on the indoor side and need to be manually unlocked by people inside. This design can meet certain safety needs under normal use, but it has obvious defects in emergency situations. On the one hand, when an emergency such as a fire occurs inside the building, the room may quickly fill with smoke and high temperature. Trapped people may not be able to reach the rescue window in time to unlock the door due to obstructed vision, mobility problems or injuries, resulting in the inability to open the escape route. On the other hand, when external rescue personnel carry out rescue operations, because traditional rescue windows cannot be opened directly from the outside, they can only rely on forced entry by means such as demolition. This not only consumes a lot of time and energy, but may also cause further damage to the building structure, delaying the best time for rescue. Summary of the Invention

[0004] In view of the above-mentioned technical problems, the purpose of the present invention is to provide a hidden rescue window with a cross-distance unlocking structure.

[0005] The technical solution of the present invention is achieved as follows: a hidden rescue window with a cross-distance unlocking structure is installed in a reserved window hole of the main structure of the building, comprising

[0006] An aluminum alloy window frame, wherein the periphery of the aluminum alloy window frame is connected and fixed to the inner wall of the reserved opening, and a vertical locking groove is opened in the middle of one side of the aluminum alloy window frame;

[0007] The aluminum alloy window sash is hinged on the side of the aluminum alloy window frame opposite to the lock groove. A guide rail is fixedly provided on the upper part of the opening side of the aluminum alloy window sash, and the guide rail has a first hollow round tube; a directional lock is provided in the middle part of the opening side of the aluminum alloy window sash for vertical sliding, and a second hollow round tube is provided on the rear side of the directional lock. The directional lock has a U-shaped card seat with a downward opening, and the U-shaped card seat cooperates with the lock groove on the aluminum alloy window frame.

[0008] Among them, when the directional lock slides downward, the U-shaped clamping seat is clamped into the lock groove to lock the aluminum alloy window sash and the aluminum alloy window frame. When the directional lock slides upward, the U-shaped clamping seat disengages from the lock groove to unlock the aluminum alloy window sash and the aluminum alloy window frame;

[0009] A stainless steel lifting rope that sequentially passes through the second round tube and the first round tube from bottom to top and finally extends to the outside of the building along the upper edge of the aluminum alloy window sash. The lower end of the stainless steel lifting rope is fixedly connected to the lower end of the directional lock to drive the directional lock to move up and down;

[0010] A rescue window panel fixedly connected to the outside of the aluminum alloy window sash, and the area of the rescue window panel is larger than that of the aluminum alloy window sash.

[0011] Preferably, a plurality of stainless steel hinges are evenly spaced between the aluminum alloy window sash and the aluminum alloy window frame, and the aluminum alloy window sash and the aluminum alloy window frame are rotationally matched through the plurality of stainless steel hinges.

[0012] Preferably, the stainless steel hinge includes a fixed shaft and two movable blades rotatably arranged on the fixed shaft.

[0035] As shown in the Figures 1-6 accompanying drawings, a hidden rescue window with a cross-distance unlocking structure according to the present invention is installed in the reserved window opening 11 of the building main structure 1, and includes an aluminum alloy window frame 2, an aluminum alloy window sash 3, a stainless steel lifting rope 4 and a rescue window panel 5.

[0036] The four sides of the aluminum alloy window frame 2 are fixed to the inner wall of the reserved opening by long screws 7. To ensure the installation accuracy and stability, a spacer 8 is provided between the aluminum alloy window frame 2 and the reserved opening. The spacer 8 can be made of rubber or hard plastic and is evenly distributed between the aluminum alloy window frame 2 and the reserved opening. A vertical lock groove 21 (not shown in the figure) is provided in the middle of one side of the aluminum alloy window frame 2.

[0037] A waterproof aluminum plate 9 is provided on the outside of the connection position between the aluminum alloy window frame 2 and the reserved opening. One end of the waterproof aluminum plate 9 is fixed to the outer edge of the aluminum alloy window frame 2 by screws, and the other end extends and is fixed to the inner wall of the reserved opening, forming a waterproof sealing structure to prevent rainwater from seeping into the room.

[0038] The aluminum alloy window sash 3 is hinged to one side of the aluminum alloy window frame 2 relative to the lock groove 21 by a plurality of stainless steel hinges 6. Among them, the stainless steel hinge 6 includes a fixed shaft 61 and two movable blades 62 rotatably arranged on the fixed shaft 61. The fixed shaft 61 is fixed to the side of the aluminum alloy window frame 2 by welding or screw connection, and the two movable blades 62 are respectively fixed to the side of the aluminum alloy window sash 3 and the aluminum alloy window frame 2 by screws, realizing the rotational cooperation between the aluminum alloy window sash 3 and the aluminum alloy window frame 2. In this embodiment, a plurality of stainless steel hinges 6 are evenly spaced to ensure smooth opening of the aluminum alloy window sash 3.

[0039] A guide rail 31 is fixedly provided at the upper part of the opening side of the aluminum alloy window sash 3. As shown in the appendix Figure 7 The guide rail 31 is a long strip-shaped metal part, and the guide rail 31 has a first round tube 311 with a hollow structure. The axis of the first round tube 311 is consistent with the length direction of the guide rail 31. A directional lock 32 is slidably arranged vertically in the middle of the opening side of the aluminum alloy window sash 3. Among them, a long groove for the directional lock 32 to slide up and down is provided in the middle of the opening side of the aluminum alloy window sash 3. During specific operation, a guiding structure, such as a guiding rib or a groove, can be provided inside the long groove to ensure smooth sliding of the directional lock 32.

[0040] The rear side of the directional lock 32 has a second round tube 321 with a hollow structure. The second round tube 321 is located in the long groove and is coaxially arranged with the first round tube 311. The directional lock 32 has a U-shaped card seat 322 with an opening downward. In this embodiment, the U-shaped card seat 322 is arranged at the front end of the directional lock 32. The depth and width of the lock groove 21 are adapted to the U-shaped card seat 322 of the directional lock 32, and the U-shaped card seat 322 cooperates with the lock groove 21 on the aluminum alloy window frame 2.

[0041] Among them, when the directional lock 32 slides downward, the U-shaped card seat 322 is clamped into the lock groove 21 to lock the aluminum alloy window sash 3 and the aluminum alloy window frame 2; when the directional lock 32 slides upward, the U-shaped card seat 322 disengages from the lock groove 21 to unlock the aluminum alloy window sash 3 and the aluminum alloy window frame 2.

[0042] The stainless-steel lifting rope 4 passes through the second circular tube 321 and the first circular tube 311 from bottom to top, and finally extends to the outside of the building along the upper edge of the aluminum alloy window sash 3. The lower end of the stainless-steel lifting rope 4 is fixedly connected to the lower end of the directional lock 32 to drive the directional lock 32 to move up and down.

[0043] In this embodiment, the stainless-steel lifting rope 4 is woven from high-strength stainless-steel wires and has good tensile properties.

[0044] Furthermore, a ball head 41 is fixedly arranged at the end of the stainless-steel lifting rope 4 extending to the outside of the building. The ball head 41 can prevent the stainless-steel lifting rope 4 from falling off from the outside, and at the same time is convenient for rescue personnel to grasp and operate.

[0045] [[ID=io]]The rescue window panel 5 is a cement fiber board. The rescue window panel 5 is fixedly connected to the outside of the aluminum alloy window sash 3 by screws or adhesives. The area of the rescue window panel 5 is larger than that of the aluminum alloy window sash 3, covering the gap between the edge of the aluminum alloy window sash 3 and the aluminum alloy window frame 2, forming a concealed structure, making the appearance of the rescue window consistent with the surrounding curtain wall and not affecting the overall beauty of the building.

[0046] The working principle of the present invention is as follows:

[0047] When it is necessary to unlock the rescue window from the outside, the rescue personnel pull the ball head 41 on the outside of the building, lift the directional lock 32 upward through the stainless-steel lifting rope 4. The second circular tube 321 slides upward in the long groove, and the U-shaped clamping seat 322 disengages from the lock groove 21 of the aluminum alloy window frame 2. The aluminum alloy window sash 3 loses its lock and can be opened outward through the hinged stainless-steel hinge 6 to form an escape passage. When used normally indoors, the directional lock 32 naturally falls under the action of gravity, and the U-shaped clamping seat 322 is clamped into the lock groove 21 to ensure that the aluminum alloy window sash 3 is closed and locked, meeting the daily safety protection requirements.

[0048] The above embodiments are only used to illustrate the technical concept and features of the present invention, and their purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it, and cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
