[0084] Escape platforms are not currently available in buildings. They typically involve installing an openable escape platform on each floor of a building's exterior wall in the event of a dangerous situation. Currently, buildings are equipped with casement, sliding, top-hung, and bottom-hung windows for lighting and ventilation. However, these windows often have small opening sashes and a limited opening area, and when opened, they don't form a platform for people to gather, reducing escape opportunities and efficiency.

[0085] The escape platform is set up in a position on each floor of the building that is convenient for escape. When closed, the platform can be used as a part of the building itself, and can also be used to realize functions such as window lighting, ventilation and smoke exhaust. When opened, it can form a platform on the facade of the building with a certain carrying capacity. Escaping people can gather on it to wait for rescue or use a descent device to descend to a safe location to escape danger.

[0086] The specific structure of the escape platform provided in this application is described in detail below with reference to the accompanying drawings.

[0087] 1 to 3 , an embodiment of the present application provides an escape platform, which is installed in an opening of a building. The position of the escape platform needs to be ensured to meet the requirements of the building's facade effect. The escape platform includes a carrying platform 4 and a fixing frame 1.

[0088] The carrying platform 4 is movably connected to the fixed frame 1. The fixed frame 1 can be a rectangular metal frame. The fixed frame 1 is fixed in the opening of the building. The carrying platform 4 can be a high-strength transparent window. The bottom end of the carrying platform 4 is hinged to the inner wall of the bottom end of the fixed frame 1.

[0089] When the carrying platform 4 is in the closed state, the carrying platform 4 is clamped in the fixing frame 1 to block the opening, so that the building can be normally lit and heat-insulated;

[0090] When the carrying platform 4 is in the open state, the carrying platform 4 rotates toward the outside of the building and moves to the outside of the building facade. The carrying platform 4 can reach a horizontal state to form a platform for escaping personnel to stay. The escaping personnel stand on the carrying platform 4, which is located outside the building and away from the fire inside the building. The escaping personnel can gather on it to wait for rescue or use the descent device to descend to a safe position to escape danger.

[0091] In some embodiments, a first sealing body 440 is provided in the four sides of the supporting platform 4. When the supporting platform 4 is in a closed state, the first sealing body 440 is squeezed and sealed with the second sealing body 110 provided on the inner side of the fixed frame 1. A guardrail 6 is provided on the supporting platform 4. The guardrail 6 is located at the edge of the supporting platform 4 and is hidden in the first accommodating space 111 of the two side frames 11 of the fixed frame 1 in a foldable form, and is foldably hidden in the second accommodating space 112 of the upper frame of the fixed frame 1.

[0092] As shown in FIG1 , in some embodiments, a diagonal member 5 is further included. The diagonal member 5 is disposed between the two side edges of the carrying platform 4 and the two side frames of the fixing frame 1 , and the diagonal member 5 is hidden in the first accommodation space 111 of the two side frames of the fixing frame 1 .

[0093] When the carrying platform 4 is in the closed state, the inclined member 5 is hidden in the first accommodation space 111 of the two side frames of the fixing frame 1;

[0094] When the carrying platform 4 is in the open state, the inclined member 5 is unfolded between the carrying platform 4 and the fixed frame 1 to increase the carrying capacity of the carrying platform 4 .

[0095] In order to ensure the safety of escaping personnel, the load-bearing platform 4 forms a cantilever structure with the wall after opening. The higher the escape hole is set and the longer the cantilever of the cantilever structure is, the more unfavorable it is to the load-bearing capacity of the load-bearing platform 4. Therefore, after the load-bearing platform 4 is opened, inclined-stayed components 5 connected to the load-bearing platform 4 are provided on both sides of the fixed frame 1 to enhance the load-bearing strength of the load-bearing platform 4.

[0096] The inclined component 5 can be a rod-type structure and be provided with a limit device, so that the inclined component 5 can run in a specified direction when the load-bearing platform 4 returns to a closed state, and the inclined component 5 can be located in the first accommodating chamber 111 provided on the load-bearing platform 4 or the fixed frame 1; the inclined component 5 can also be a telescopic component, which extends or retracts to a set direction when the load-bearing platform 4 is opened, and is located in the accommodating space of the load-bearing platform 4 or the fixed frame 1 when the load-bearing platform 4 returns to a closed state; the inclined component 5 can also be a rope-type or chain-type component, which extends to a set position and stops running when the load-bearing platform 4 is in an open state, and a counterweight structure or a friction structure can be provided at one end of the rope-type or chain-type component to enable the load-bearing platform 4 to open slowly.

[0097] As shown in Figure 2, in some embodiments, a recovery device 3 is also included. The recovery device 3 is set on the fixed frame 1. After the carrying platform 4 is opened to complete the escape mission, the various functions and components of the carrying platform 4 are checked. After checking that the various functions and components of the carrying platform 4 are not damaged, the recovery device 3 can be used to manually restore the carrying platform 4 to a closed state from the indoor side, and the locking is achieved through the locking structure set on the fixed frame 1 and the carrying platform 4. After the carrying platform 4 is restored to its initial state, the carrying platform 4 can still be reused.

[0098] Specifically, a rope-like component can be used to connect the recovery device 3 and the carrying platform 4, that is, one end of the rope-like component is connected to the carrying platform 4, and the other end is connected to the pulley of the recovery device 3, and the pulley is controlled by the one-way movement principle of the pawl, that is, the tool corresponding to the pawl can be used to rotate the pulley, so that the rope-like component is wound around the pulley, pulling the carrying platform 4 to restore to its initial state; chain-like components can also be used, and the chain and sprocket are coordinated. The chain is contracted by rotating the sprocket, and the contracted chain enters the set accommodation space, pulling the carrying platform 4 to restore to its initial closed state and achieve locking; a screw rod structure can also be used to achieve recovery, and the screw rod is rotated to make the nut connected to the wire link move linearly, and the nut rope component, chain component or connecting rod component is linked to the escape platform, and the nut runs in the set direction to restore the escape platform to its initial state and lock it.

[0099] 4 and 5 , in some embodiments, a manual switch 2 is further included, and the manual switch 2 includes;

[0100] The operating part 210 is used to manually unlock the escape platform by the trapped person. Therefore, it can be set on the side of the fixed frame 1 facing the room. When the trapped person in the room is affected by the fire, the operating part 210 can be manually operated to realize the deployment of the escape platform; the specific form of the operating part 210 is not limited to a handle, a handle, or a rocker. The shape and layout direction of the operating part 210 should be conducive to the operator's force so as to quickly deploy the operating platform.

[0101] An actuator 220 connected to the operating unit 210 is movably connected to the fixed frame 1; one end of the actuator 220 is connected to the operating unit 210, and the other end may be located inside, on, or outside the fixed frame 1; the operating unit 210 is configured to move along a first direction to drive the other end of the actuator 220 to move along the first direction;

[0102] There can be multiple connection methods between the execution unit 220 and the fixed frame 1. For example, in some embodiments, the execution unit 220 can be slidably connected to the fixed frame 1. In this case, the first direction is the sliding direction, corresponding to the operator's operation of holding the operation unit 210 closer to or away from the fixed frame 1; in other embodiments, the execution unit 220 can also be rotationally connected to the fixed frame 1, that is, the first direction is rotation upward, downward, or any other direction.

[0103] In the present application, the function of the execution part 220 can be to directly transmit the operator's force to the pushing part 240 in a predetermined direction, that is, to push the pushing part 240 along the second direction to push the carrying platform to the outdoor side along the second direction; the function of the execution part 220 can also be to transmit the operator's force to the unlocking part 230 in a predetermined direction, so that the unlocking part 230 can also push the pushing part in the second direction, forming an auxiliary pushing effect on the pushing part 240, thereby realizing the unlocking of the carrying platform 4 and the fixed frame 1.

[0104] As can be seen from Figure 4, the device also includes an unlocking part 230 and a pushing part 240 arranged inside the fixed frame 1; the pushing part 240 is movably connected to the supporting platform 4; wherein, the unlocking part 230 has a controlled end (force input position) and an execution end (force output position) according to the direction of force conduction, the controlled end is connected to the end of the execution part 220 away from the operating part 210, and the execution end of the unlocking part 230 is connected to the pushing part 240; the end of the pushing part 240 is a structure that can be engaged with the supporting platform 4, and it should be considered that its end can be directly engaged with the supporting platform 4, or it can also be engaged with a fixed structure fixed to the supporting platform 4 (for example, Figure 4 shows an embodiment in which a similar hook structure is provided on the supporting platform 4); the unlocking part 230 is configured to push the pushing part 240 along the second direction when the other end of the execution part 220 moves along the first direction, so as to achieve unlocking of the supporting platform 4 and the fixed frame 1.

[0105] In some embodiments, the pusher 240 may not be provided, and the actuating end of the unlocking portion 230 may be directly engaged with the carrier platform 4, thereby achieving unlocking between the carrier platform 4 and the fixed frame 1 through the unlocking portion 230. Therefore, in the embodiment of the present application, the actuating portion 220 may simultaneously control the pusher 240 and / or the unlocking portion 230 to achieve the unlocking operation.

[0106] It should be noted that in this embodiment, the locking structure of the ejection part 240 and the supporting platform 4 is not limited to one group. For example, multiple ejection parts 240 can be evenly distributed within the expanded surface of the supporting platform 4, and the multiple ejection parts 240 are driven by the unlocking part 230 at the same time, and then multiple fixed structures corresponding to the ejection part 240 are arranged on the supporting platform 4, thereby increasing the stability and structural strength during locking.

[0107] In some embodiments, further comprising a protective structure;

[0108] The manual switch 2 is provided with a protective structure. Under normal circumstances, the manual switch 2 is sealed inside the protective structure to prevent the manual switch 2 from being accidentally touched. When in use, the manual switch 2 can be operated by opening or removing the protective structure.

[0109] 6 and 7 , in some embodiments, a guardrail 6 is further provided on the carrying platform, and the guardrail 6 includes:

[0110] The armrest portion 610 is a rod-shaped structure; the armrest portion 610 is connected to the guardrail lifting device. When the armrest portion 610 is rotated in the direction away from the room through the carrying platform 4, the armrest portion 610 is lifted by the guardrail lifting device until the carrying platform 4 is perpendicular to the fixed frame 1, and the distance between the armrest portion 610 and the carrying platform 4 reaches a preset value.

[0111] The support portion 620 is arranged between the armrest portion 610 and the carrying platform 4; the guardrail 6 is folded into the accommodating space of the fixing frame 1, and the risk of escaping personnel falling from the carrying platform 4 can be prevented.

[0112] The fixing portion is slidably connected to the accommodation space of the fixing frame 1 and is rotatably connected to both ends of the armrest portion 610. When the distance between the supporting platform 4 and the armrest portion 610 reaches a preset value, the support portion 620, the armrest portion 610, and the supporting platform 4 are self-locking. A self-locking structure is provided between the support portion 620, the armrest portion 610, and the supporting platform 4. When the distance between the supporting platform 4 and the armrest portion 610 reaches a preset value, the support portion 620 is deployed and locked, preventing an escaping person on the supporting platform 4 from pressing the upper armrest portion 610 of the guardrail 6, causing the guardrail 6 to transition from an deployed state to a folded state, thereby causing the escaping person to fall off the guardrail 6.

[0113] When the carrying platform 4 is opened, the guardrail 6 folded and hidden in the accommodating space of the fixed frame 1 is also opened. When the carrying platform 4 is opened to the set position, the guardrail 6 is also unfolded to the set position and locked. The purpose of locking is to prevent the escapee on the carrying platform 4 from pressing the upper handrail 610 of the guardrail 6, causing the guardrail 6 to be converted from the unfolded state to the folded state, thereby causing the hidden danger of the escapee falling from the guardrail 6.

[0114] In some embodiments, the guardrail 6 is connected to the three sides of the support platform 4 that are not rotatably connected to the fixed frame 1, and the two ends of the guardrail 6 close to the fixed frame 1 are slidably connected to the fixed frame 1; wherein, the guardrail 6 can be connected to the inside of the fixed frame 1 or to the accommodation space provided outside the fixed frame 1, which is not limited here; when the escapee is on the support platform 4, the guardrail 6 is used to provide protection to prevent the escapee from falling from the support platform 4;

[0115] The escape platform also includes a guardrail lifting device, which includes a lifting portion 630, and the lifting portion 630 is arranged in the fixed frame 1, or between the supporting platform 4 and the fixed frame 1; wherein, when the supporting platform 4 moves in a first direction, the guardrail 6 moves along the second direction through the lifting portion 630 to achieve a distance between the guardrail 6 and the supporting platform 4 reaching a preset value; the first direction is the direction away from the room; the second direction is the direction in which the guardrail 6 is deployed, that is, the direction away from the supporting platform 4.

[0116] The guardrail lifting device provided in the present application is such that during the opening process of the load-bearing platform 4, the guardrail 6 arranged around the load-bearing platform 4 can also be raised in conjunction. When the guardrail 6 is raised, the gravity when the load-bearing platform 4 is opened can be used to pull the guardrail 6 to the set position through the lifting part 630, as shown in Figure 6. When the guardrail 6 is raised, its running trajectory can be limited by the guide component. When the load-bearing platform 4 is opened to the set position, the guardrail 6 is raised to the set position by the escape platform guardrail lifting device and self-locks, as shown in Figure 7, providing protection for the escaping personnel on the load-bearing platform 4, thereby improving the safety of the escaping personnel when they are on the load-bearing platform 4.

[0117] 8 to 10 , in some embodiments, a fireproof and heat-insulating curtain 9 is further included. The fireproof and heat-insulating curtain 9 includes:

[0118] The shape of the frame 910 is not limited, but because the openings in the building are usually rectangular, the fixed frame 1 is designed to be a rectangle that matches the opening. Therefore, the frame 910 is usually designed as a rectangular frame, and the outer contour of the frame 910 matches the inner contour of the opening, and the frame 910 is fixed in the opening; or the outer contour of the frame 910 matches the inner contour of the fixed frame 1, and the frame 910 is fixed in the fixed frame 1.

[0119] The top of the frame 910 has a certain thickness. The top of the frame 910 is provided with a receiving cavity 911. The receiving cavity 911 can be a rectangular cavity or a cylindrical cavity. The outer wall of the frame 910 is provided with an outlet 912 connected to the receiving cavity 911. The outlet 912 can be a long strip opening and is vertically downward.

[0120] A reeling mechanism 920 is provided on the frame 910, and the reeling portion of the reeling mechanism 920 is located within the accommodating chamber 911; a fireproof rolling curtain 930 is provided within the accommodating chamber 911, and the inner end of the fireproof rolling curtain 930 is connected to the reeling portion of the reeling mechanism 920, and the outer end of the fireproof rolling curtain 930 passes through the outlet 912 and extends outside the accommodating chamber 911; a movable frame 940 is connected to the outer end of the fireproof rolling curtain 930, and the movable frame 940 can be a rectangular parallelepiped frame, and the length of the movable frame 940 matches the inner contour width of the frame 910;

[0121] The locking mechanism 950 is used to fix the fireproof roller shutter 930. The locking mechanism 950 includes a first locking part and a second locking part. The first locking part is arranged on the bottom inner wall of the frame 910, or the bottom end of the side wall, and the second locking part is arranged on the movable frame 940.

[0122] When the fireproof rolling curtain 930 moves downward to reach a fully closed state, the first locking part and the second locking part are engaged, preventing the fireproof rolling curtain 930 from moving upward, thereby fixing the fireproof rolling curtain 930 in a closed state, stably blocking indoor smoke and open flames, and ensuring the safety of escaping personnel.

[0124] As shown in Figure 12, the fixing seat 710 can be a metal connecting seat, which includes a horizontally arranged fixing plate and a vertically arranged connecting plate. The fixing plate can be fixed on the supporting platform, the fixing frame or the facade of the building, and multiple connecting plates are vertically arranged on the fixing plate.

[0125] The rotating shaft 720 passes through multiple fixing plates of the fixing seat 710 and is rotatably connected to the fixing seat 710. The cable assembly 730 and the friction part 740 are both sleeved on the rotating shaft 720 and are coaxially arranged with the rotating shaft 720. The cable assembly 730 is fixedly connected to the rotating shaft 720, and the friction part 740 is fixedly connected to the fixing seat 710. When the escapee descends to escape through the cable assembly 730, the cable assembly 730 drives the rotating shaft 720 to perform a first rotational motion, which can be a clockwise rotational motion.

[0126] The damping mechanism 750 is disposed between the friction portion 740 and the rotating shaft 720 . The damping mechanism 750 is connected to the rotating shaft 720 , and the rotating shaft 720 drives the damping mechanism 750 to rotate synchronously.

[0127] When the cable assembly 730 drives the rotating shaft 720 and the damping mechanism 750 to perform the first rotational motion, the damping mechanism 750 slides and rubs against the friction part 740, and the friction force applies a reverse force to the damping mechanism 750 and the rotating shaft 720 to hinder the first rotational motion, thereby reducing the rotation speed of the rotating shaft 720, reducing the release speed of the cable assembly 730, and thereby reducing the descent speed of the escaping person, thereby preventing the escaping person from being injured due to the excessively fast descent speed.

[0128] The slow-descent device provided in the present application has a fixed seat 710 that can be set on the supporting platform 4 or the fixed frame 1. The fixed seat 710 can also be set on the facade of the building and is in a fixed state. When using the slow-descent device, there is no need to find a safe hanging point or support indoors, and it is easy to use. When escaping, the user descends to escape by pulling the cable. During the descent, when the cable assembly 730 drives the rotating shaft 720 and the damping mechanism 750 to perform a first rotational motion, the damping mechanism 750 and the friction part 740 slide and rub. The friction force applies a reverse force to the damping mechanism 750 and the rotating shaft 720 to hinder the first rotational motion, so as to reduce the rotation speed of the rotating shaft 720, reduce the release speed of the cable assembly 730, and thereby reduce the descent speed of the escaping person, so that the escaping person descends slowly and achieves a safe and rapid descent escape.

[0129] In some embodiments, the cable assembly 730 includes a cable and a turntable;

[0130] The turntable is sleeved on the rotating shaft 720 and is fixedly connected to the rotating shaft 720. The turntable and the rotating shaft 720 rotate in the same direction and at the same speed.

[0131] The cable can be a drawstring, which is wound around the turntable, and a connecting ring is provided at the outer end of the cable;

[0132] When the escapee descends through the cable, the cable drives the turntable and the shaft 720 to perform a first rotational motion;

[0133] The damping mechanism 750 includes a first guide member 751 and a friction block 752;

[0134] The first guide member 751 can be a rod body, and there can be several first guide members 751. Preferably, multiple first guide members 751 are evenly distributed around the rotating shaft 720. The first guide member 751 is connected to the rotating shaft 720. The extension direction of the first guide member 751 is perpendicular to the axial direction of the rotating shaft 720. The outer end of the first guide member 751 extends toward the friction part 740; the friction block 752 can be a ring body, and the outer end of the friction block 752 is the friction surface. The friction block 752 is sleeved on the first guide member 751, and the distance between the outer end of the first guide member 751 and the inner wall of the friction part 740 is less than the height of the friction block 752 to prevent the friction block 752 from separating from the first guide member 751.

[0135] The rotating shaft 720 drives the first guide member 751 and the friction block 752 to rotate synchronously. The outer wall of the friction block 752 and the inner wall of the friction part 740 dynamically rub against each other. As the escaping person descends faster, the rotation speed of the turntable and the rotating shaft 720 accelerates, the relative speed of the friction part 740 and the friction block 752 increases, the outward centrifugal force on the friction block 752 increases, the pressure of the friction block 752 on the friction part 740 increases, and the dynamic friction between the two increases, thereby increasing the reverse force that hinders the first rotational motion on the friction block 752, thereby reducing the rotation speed of the rotating shaft 720 and the turntable, and then reducing the descent speed of the escaping person, thereby preventing the escaping person from being injured due to the excessive descent speed.

[0136] 13 and 14 , in some embodiments, a platform slow-release device is further included, and the platform slow-release device includes:

[0137] The third connecting part 410; one end of the third connecting part 410 is connected to the movable end of the carrying platform 4; wherein, the movable end of the carrying platform 4 refers to the end away from the hinged position with the fixed frame 1, that is, the end that is extended outward; as the carrying platform 4 extends outward, the third connecting part 410 will be pulled outward along the expansion direction. For the third connecting part 410, it is pulled by the carrying platform 4 to produce an angle and length movement, thereby driving the running part 420 at the other end to make corresponding movements.

[0138] The operating part 420 is linked to the third connecting part 410; the operating part 420 is configured as follows: when the movable end of the supporting platform 4 is opened to the outdoor side, it is driven by the third connecting part 410 to perform a first movement; the first movement can be a rotational movement, or a movement along a straight line or a curve; it should be noted that, in this embodiment, the linkage between the third connecting part 410 and the operating part 420 can be in various forms. For example, when the third connecting part 410 is a rope-shaped cable and the operating part 420 is a turntable or a roller, when the third connecting part 410 is pulled, it can drive the operating part 420 to rotate, so the simultaneous pulling and rotation is called linkage; it should be understood that when the third connecting part 410 and the operating part 420 are different structures, the linkage method between the two can be different; in this application, one of the methods is used as an example, and at this time, the third connecting part 410 can drive the operating part 420 to perform the first movement.

[0139] The release portion 430 is provided in the fixed frame 1, and the release portion 430 is configured to apply a reverse force to the operating portion 420 that hinders the first movement. In the present application, the release portion 430 can be provided at any position of the fixed frame 1, such as on the upper side, the side or the bottom side. Depending on the different settings, the release portion 430 can also be provided with different structures. When the release portion 430 provides a reverse force to the operating portion 420 that hinders the first movement, it can slow down the speed of the first movement. At the same time, due to the linkage between the operating portion 420 and the third connecting portion 410, the speed at which the third connecting portion 410 is pulled out is also slowed down. Furthermore, the release portion 430 provided in the present application can slow down the speed or acceleration of the outward expansion of the supporting platform 4, thereby reducing the impact force on the connecting components during the expansion of the supporting platform 4.

[0140] It can be seen from the above technical solution that the present application sets a third connecting part 410 connected to the carrying platform 4, and a running part 420 linked to the third connecting part 410, and at the same time uses a release part 430 set in the fixed frame 1 to slow down the movement of the running part 420, thereby achieving the purpose of reducing the deployment speed of the carrying platform 4, and ensuring the safety and stability of the deployment process of the carrying platform 4.

[0141] 15 and 16 , in some embodiments, a supporting platform frame connection structure is further included, and the supporting platform frame connection structure includes:

[0142] The first connecting portion 450 is fixed to the bottom of the fixing frame 1 and is close to the outdoor side;

[0143] The second connection part 460 is rotatably connected to the first connection part 450 through the rotating part 470; the second connection part 460 is fixedly connected to the side of the supporting platform 4 close to the outdoors; in this embodiment, the first connection part 450 and the second connection part 460 can be in the shape of slats, steel bars or other shapes, and should be considered as components providing a connection function, and the first connection part 450 and the second connection part 460 are switched relative to each other to switch the opening and closing state between the supporting platform 4 and the fixed frame 1. The opening and closing state includes a closed state and an expanded state. The closed state refers to the state where the supporting platform 4 is completely located inside the fixed frame 1. The expanded state includes the state where the supporting platform 4 has just rotated relative to the fixed frame 1 and begins to expand outward, and also includes the state where the supporting platform 4 rotates outward to be perpendicular to the fixed frame 1.

[0144] The second connection portion 460 is used to drive the carrying platform 4 to rotate along the first direction; the first direction is the direction in which the carrying platform 4 is unfolded from the closed state to the outside;

[0145] The supporting platform frame connection structure also includes a stopper 480 connected between the first connecting portion 450 and the second connecting portion 460. The stopper 480 is used to prevent the supporting platform 4 from rotating in a second direction, which is opposite to the first direction. In actual use, if the platform is deployed and is subject to strong wind resistance, it may be difficult to deploy the platform, hindering trapped personnel from quickly reaching the platform for safety. In this embodiment, the stopper 480 prevents the supporting platform 4 from rotating in the opposite direction when it is deployed, thereby increasing the deployment speed of the supporting platform 4.

[0146] As shown in FIG17 , in some embodiments, an escape platform opening reinforcement device is further included, and the escape platform opening reinforcement device includes:

[0147] An embedded portion 120 is provided around the building's facade opening; the embedded portion 120 includes, but is not limited to, steel plates, steel mesh, steel pipes, steel bars, angle steels, and channel steels. An auxiliary frame portion 130 is provided around the building's facade opening, and includes, but is not limited to, steel plates, steel pipes, angle steels, and channel steels. The auxiliary frame portion 130 can be used to reduce the shear force exerted on the fixed frame 1 and the opening fixing components when the support platform 4 is opened. The fixed frame 1 is connected to the embedded portion 120 and the auxiliary frame portion 130 via a first fixing portion 140, which includes, but is not limited to, expansion bolts, bolts, and screws. In the present application, the embedded portion 120 is pre-embedded within the periphery of the opening on the building facade, and the attached frame portion 130 is arranged outside the periphery of the opening on the building facade and fixedly connected to the embedded portion 120 and the fixed frame 1 through the first fixing portion 140, thereby strengthening the connection strength between the fixed frame 1 and the building facade, and further enhancing the connection strength of the supporting platform 4, so that when the escaping personnel are stranded on the supporting platform 4, the supporting platform 4 has a certain load-bearing capacity and stability, and the supporting platform 4 can still remain stable in windy weather;

[0148] One side of the attachment frame portion 130 is connected to the embedded portion 120 via the first fixing portion 140, and the other side is positioned near the building's facade opening, close to the interior. For example, the attachment frame portion 130 can be an L-shaped structure, with one side positioned near the building's facade opening, close to the interior. This serves to reduce shear forces acting on the fixing frame 1 and the opening's fixing components when the support platform 4 is opened, further improving the stability between the fixing frame 1 and the building facade.

[0152] As shown in FIG18 , B in FIG18 is an escape slow-down device provided on the escape platform, and the connector 830 is the connecting portion of the escape slow-down device B.

[0153] A hidden cavity is provided in the fixing frame 1 or the wall of the building. The hidden cavity may be a rectangular cavity or a cavity of other shapes. The fixing portion 810 may be directly fixedly connected to the inner wall of the hidden cavity or may be fixed in the hidden cavity through other fixing parts.

[0154] The supporting portion 820 can be a rod-shaped structure, and the supporting portion 820 is movably connected to the fixing portion 810. One end of the supporting portion 820 is rotatably connected to the fixing portion 810, and the other end can be rotated along the first direction until the other end of the supporting portion 820 moves to the outside of the hidden cavity; multiple connecting parts 830 are arranged on the supporting portion 820.

[0155] The support portion 820 can rotate freely. When in use, the support portion 820 rotates along the first direction until the outer end of the support portion 820 moves to the outside of the hidden cavity and reaches the set position. At this time, the user can slowly descend through the connecting piece 830.

[0156] When not in use, the support portion 820 can drive the connecting member 830 to rotate and completely enter the hidden cavity, thereby concealing the storage, avoiding damage, and improving the aesthetics.

[0159] When the carrying platform 4 is opened, the carrying platform 4 drives the moving part 170 to move in the first direction, and the second clamping part 171 is slidably connected to the first clamping part 161; when the carrying platform 4 drives the moving part 170 to move in the second direction, the second direction is opposite to the first direction, and the second clamping part 171 is clamped with the first clamping part 161 to prevent the carrying platform 4 from moving in the second direction, that is, to prevent the carrying platform 4 from moving in the opposite direction, thereby ensuring that the carrying platform 4 opens quickly and buys time for the escaping personnel to escape.

[0160] When the carrying platform 4 is closed, the carrying platform 4 can be closed normally by manually separating the one-way stop portion 160 and the moving portion 170 .

When unfolded, the angle between the carrying platform 4 and the fixed frame reaches a preset angle value, forming a platform for escaping personnel to escape.
