[0097] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0098] Escape platforms are not installed on current buildings. When dangerous situations occur, an escape platform is installed on each floor of the building, which can be opened to form an escape platform on the building's exterior wall surface. Currently, buildings are equipped with casement, sliding, top-hung and bottom-hung windows for lighting and ventilation, but the opening sashes and opening areas of the windows are small, and after opening, they cannot form a platform for people to gather, which reduces the chance and efficiency of escape.

[0099] The escape platform is set at 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 open, it can form a platform on the facade of the building with a certain carrying capacity. Escaping personnel can gather on it to wait for rescue or use a descent control device to descend to a safe location to escape danger.

[0100] The specific structure of the escape platform provided by the present application is described in detail below in conjunction with the accompanying drawings.

[0101] Reference Figure 1-Figure 3 As shown, the embodiment of the present application provides an escape platform, which is installed in an opening of a building. At the same time, it is necessary to ensure that the location of the escape platform meets the requirements of the facade effect of the building. The escape platform includes a bearing platform 4 and a fixed frame 1;

[0102] The bearing 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 bearing platform 4 can be a high-strength transparent window, and the bottom end of the bearing platform 4 is hinged to the inner wall of the bottom end of the fixed frame 1;

[0103] 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, and the building can be normally lit and heat-insulated;

[0104] When the supporting platform 4 is in the open state, the supporting platform 4 rotates toward the outside of the building and moves to the outside of the building facade. The supporting platform 4 can reach a horizontal state to form a platform for escapees to stay. The escapees stand on the supporting platform 4, which is located outside the building and away from the fire in the building. The escapees can gather on it and wait for rescue or use the slow-descent device to descend to a safe position to escape danger.

[0105] In some embodiments, a first sealing body 440 is provided in the surrounding frames of the carrying platform 4. When the carrying platform 4 is in a closed state, the first sealing body 440 is squeezed and sealed with a second sealing body 110 provided on the inner side of the fixed frame 1. A guardrail 6 is provided on the carrying platform 4. The guardrail 6 is located at the edge of the carrying 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 also hidden in the second accommodating space 112 of the upper frame of the fixed frame in a foldable form.

[0106] Reference Figure 1 As shown, in some embodiments, it further includes an oblique-bracing component 5, which is arranged between the two side edges of the bearing platform 4 and the two side frames of the fixing frame 1, and the oblique-bracing component 5 is hidden in the first accommodating space of the two side frames of the fixing frame 1;

[0107] When the carrying platform 4 is in a closed state, the inclined member 5 is hidden in the first accommodation space of the two side frames of the fixing frame 1;

[0108] When the bearing platform 4 is in the open state, the inclined member 5 is unfolded between the bearing platform 4 and the fixed frame 1 to increase the bearing capacity of the bearing platform 4 .

[0109] In order to ensure the safety of the escapees, the load-bearing platform 4 forms a cantilever structure with the wall after it is opened. 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.

[0110] 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 a first accommodating room provided by 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 or a set position when the load-bearing platform 4 is opened, and the telescopic component 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, and when the load-bearing platform 4 is in an open state, the rope-type or chain-type component extends to a set position and stops running, 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.

[0111] Reference Figure 2 As shown, in some embodiments, a recovery device 3 is also included, and the recovery device 3 is arranged on the fixed frame 1. After the carrying platform 4 is opened to complete the escape task, the various functions and components of the carrying platform 4 are checked. When the various functions and components of the carrying platform 4 are checked to be intact, 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 by a locking structure arranged 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.

[0112] 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 rope pulley of the recovery device 3, and the rope 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 rope pulley, so that the rope-like component is wound around the rope pulley, and the carrying platform 4 is pulled back to its initial state; chain-like components can also be used, and the chain cooperates with the sprocket, and the chain is contracted by rotating the sprocket, and the contracted chain enters the set accommodating space, pulling the carrying platform 4 back to its initial state, closed state, and locked; recovery can also be achieved using a screw rod structure, and the screw rod is rotated to make the nut connected to the wire link move in a straight line, and the nut rope component, chain component or connecting rod component is connected to the escape platform, and the nut runs in the set direction to restore the escape platform to its initial state and lock it.

[0113] Reference Figure 4 and Figure 5 As shown, in some embodiments, a manual switch 2 is further included, and the manual switch 2 includes;

[0114] The operating part 210 is used to realize manual unlocking of the escape platform by the trapped person, so 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 the form of a handle, a handle, or a rocker, and the shape and arrangement direction of the operating part 210 should be conducive to the operator's force so as to deploy the operating platform as soon as possible.

[0115] The execution part 220 connected to the operation part 210 is movably connected to the fixed frame 1; one end of the execution part 220 is connected to the operation part 210, and the other end can be located inside, on or outside the fixed frame 1; the operation part 210 is configured to move along the first direction to drive the other end of the execution part 220 to move along the first direction;

[0116] There may be a variety of connection modes between the execution unit 220 and the fixed frame 1. For example, in some embodiments, the execution unit 220 may 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 close to or away from the fixed frame 1. In other embodiments, the execution unit 220 may also be rotatably connected to the fixed frame 1, that is, the first direction is rotation upward, downward, or in any other direction.

[0117] 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 supporting 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, thereby forming an auxiliary pushing effect on the pushing part 240, thereby realizing the unlocking of the supporting platform 4 and the fixed frame 1.

[0118] Depend on Figure 4 It can be seen that the device also includes an unlocking portion 230 and a pushing portion 240 arranged inside the fixed frame 1; the pushing portion 240 is movably connected to the carrying platform 4; wherein the unlocking portion 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 portion 220 away from the operating portion 210, and the execution end of the unlocking portion 230 is connected to the pushing portion 240; the end of the pushing portion 240 is a structure that can be connected to the carrying platform 4, and it should be considered that its end can be directly connected to the carrying platform 4, or can also be connected to a fixed structure fixedly connected to the carrying platform 4 (for example Figure 4What is shown is an embodiment in which a similar hook structure is provided on the carrying platform 4); the unlocking portion 230 is configured to push the pushing portion 240 along the second direction when the other end of the executing portion 220 moves along the first direction, so as to achieve unlocking of the carrying platform 4 and the fixed frame 1.

[0119] In some embodiments, the push-out portion 240 may not be provided, and the execution end of the unlocking portion 230 may be directly engaged with the carrier platform 4, and then the unlocking portion 230 is used to realize the unlocking between the carrier platform 4 and the fixed frame 1. Therefore, in the embodiment of the present application, the execution portion 220 may simultaneously control the push-out portion 240 and / or the unlocking portion 230 to realize the unlocking operation.

[0120] It should be noted that, in the present embodiment, the locking structure between the ejection part 240 and the supporting platform 4 is not limited to one group. For example, a plurality of ejection parts 240 may be evenly distributed within the unfolded surface of the supporting platform 4, and the plurality of ejection parts 240 may be driven by the unlocking part 230 at the same time, and a plurality of fixed structures corresponding to the ejection part 240 are correspondingly arranged on the supporting platform 4, thereby increasing the stability and structural strength during locking.

[0121] In some embodiments, further comprising a protective structure;

[0122] 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.

[0123] Reference Figure 6 and Figure 7 As shown, in some embodiments, a guardrail 6 is further included which is arranged on the carrying platform, and the guardrail 6 includes:

[0124] The armrest 610 is a rod-shaped structure; the armrest 610 is connected to the guardrail lifting device, and when the carrying platform 4 rotates in a direction away from the room, the armrest 610 is lifted by the guardrail lifting device until the carrying platform 4 is perpendicular to the fixing frame 1, and the distance between the armrest 610 and the carrying platform 4 reaches a preset value;

[0125] The support portion 620 is disposed between the handrail portion 610 and the carrying platform 4; the guardrail 6 is folded into the accommodation space of the fixing frame 1, and the risk of the escapee falling from the carrying platform 4 can be prevented;

[0126] The fixing part is slidably connected to the accommodation space of the fixing frame 1, and the fixing part is rotatably connected to the two ends of the handrail part 610; wherein, when the distance between the carrying platform 4 and the handrail part 610 reaches a preset value, the support part, the handrail part and the carrying platform are self-locking. A self-locking structure is provided between the support part, the handrail part and the carrying platform, and when the distance between the carrying platform 4 and the handrail part 610 reaches a preset value, the support part 620 is unfolded and locked to prevent the escapee on the carrying platform 4 from pressing the handrail part 610 on the upper side of the guardrail 6, causing the guardrail 6 to be converted from an unfolded state to a folded state, thereby causing the hidden danger of the escapee falling from the guardrail 6.

[0127] 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.

[0128] In some embodiments, the guardrail 6 is connected to the three sides of the carrying 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 located on the carrying platform 4, the guardrail 6 is used to provide protection to prevent the escapee from falling from the carrying platform 4;

[0129] 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 carrying platform 4 and the fixed frame 1; wherein, when the carrying 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 carrying platform 4 reaching a preset value; the first direction is a direction away from the room; the second direction is a direction in which the guardrail 6 is unfolded, that is, a direction away from the carrying platform 4.

[0130] The guardrail lifting device provided in the present application can also be linked to the guardrail 6 arranged around the carrying platform 4 during the opening process of the carrying platform 4.

[0137] Reference Fig.11 and Fig.12 As shown, in some embodiments, a descent control device 7 is further included, and the descent control device 7 includes a fixing seat 710, a rotating shaft 720, a cable assembly 730, a friction part 740, and a damping mechanism 750;

[0138] like Fig.12 As shown, the fixing seat 710 may be a metal connecting seat, which includes a horizontally arranged fixing plate and a vertically arranged connecting plate, the fixing plate may be fixed on a bearing platform, a fixing frame or a building facade, and a plurality of connecting plates are vertically arranged on the fixing plate;

[0139] The rotating shaft 720 penetrates through a plurality of fixing plates of the fixing seat 710 and is rotatably connected to the fixing seat 710. The cable assembly 730 and the friction portion 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 portion 740 is fixedly connected to the fixing seat 710. When the escapee descends through the cable assembly 730 to escape, the cable assembly 730 drives the rotating shaft 720 to perform a first rotational motion, and the first rotational motion can be a clockwise rotational motion.

[0140] 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.

[0141] 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 and the friction part 740 slide and rub, and 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 further reduce the descent speed of the escapee, so as to prevent the escapee from being injured due to the excessively fast descent speed.

[0142] The slow-descending device provided in the present application can have a fixed seat 710 that can be set on a bearing platform or a fixed frame, or can be set on the facade of a building and is in a fixed state. When using the slow-descending 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 through the cable to escape. During the descent, when the cable assembly 730 drives the rotating shaft 720 and the damping mechanism 750 to make a first rotational motion, the damping mechanism 750 and the friction part 740 slide and rub, and the friction force applies a reverse force to the damping mechanism 750 and the rotating shaft 720 that hinders 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 escapee, so that the escapee descends slowly and achieves a safe and rapid descent escape.

[0143] In some embodiments, the cable assembly 730 includes a cable and a turntable;

[0144] The turntable is sleeved on the rotating shaft and is fixedly connected to the rotating shaft. The turntable and the rotating shaft rotate in the same direction and at the same speed.

[0145] The cable can be a pull rope, the cable is wound around the turntable, and a connecting ring is provided at the outer end of the cable;

[0146] When the escapee descends through the cable, the cable drives the turntable and the shaft to perform a first rotational motion;

[0148] The first guide member 751 may be a rod body, and a plurality of first guide members 751 may be provided. Preferably, a plurality of first guide members 751 are evenly distributed around the rotating shaft, the first guide member 751 is connected to the rotating shaft, the extension direction of the first guide member 751 is perpendicular to the axial direction of the rotating shaft, and the outer end of the first guide member 751 extends toward the friction portion; the friction block 752 may be a ring body, the outer end of the friction block 752 is a 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 portion is less than the height of the friction block 752, so as to prevent the friction block 752 from detaching from the first guide member 751;

[0149] The rotating shaft drives the first guide member 751 and the friction block 752 to rotate synchronously, and the outer wall of the friction block 752 and the inner wall of the friction part dynamically rub against each other. As the escaping person descends faster, the rotation speed of the turntable and the rotating shaft increases, the relative speed of the friction part 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 increases, and the dynamic friction between the two increases, thereby increasing the reverse force on the friction block 752 that hinders the first rotational motion, thereby reducing the rotation speed of the rotating shaft and the turntable, and then reducing the descent speed of the escaping person, thereby preventing the escaping person from being injured due to the excessively fast descent speed.

[0150] Reference Fig.13 and Fig.14 As shown, in some embodiments, a platform slow-release device is also included, and the platform slow-release device includes;

[0151] The third connecting part 410; one end of the third connecting part 410 is connected to the movable end of the supporting platform 4; wherein, the movable end of the supporting platform 4 refers to the end away from the hinged position with the fixed frame, that is, the end that is extended outward; as the supporting platform 4 extends outward, the third connecting part 410 is pulled outward along the expansion direction. For the third connecting part 410, it is pulled by the supporting platform 4 to produce an angle and length movement, thereby driving the running part 420 at the other end to make corresponding movements.

[0152] An operating part 420 linked to the third connection 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 connection part 410 to perform a first movement; the first movement may be a rotational movement, or a movement along a straight line or a curve; it should be noted that, in the present embodiment, the linkage between the third connection part 410 and the operating part 420 may have various forms. For example, when the third connection part 410 is a rope-shaped cable and the operating part 420 is a turntable or a roller, when the third connection part 410 is pulled, it may drive the operating part 420 to rotate, and thus the simultaneous pulling and rotation are referred to as linkage; it should be understood that when the third connection part 410 and the operating part 420 are different structures respectively, the linkage methods of the two may be different; in the present application, one of the methods is used as an example, and at this time, the third connection part 410 may drive the operating part 420 to perform the first movement.

[0153] The slow-release portion 430 is arranged in the fixed frame 1, and the slow-release portion 430 is configured to apply a reverse force to the running portion 420 to hinder the first movement. In the present application, the slow-release portion 430 can be arranged at any position of the fixed frame 1, such as on the upper side, the side or the bottom side. According to different setting positions, the slow-release portion 430 can also be set with different structures in a targeted manner. When the slow-release portion 430 provides a reverse force to the running portion 420 to hinder the first movement, it can slow down the speed of the first movement. At the same time, due to the linkage relationship between the running portion 420 and the third connecting portion 410, the speed at which the third connecting portion 410 is pulled out is also slowed down. Therefore, the slow-release portion 430 set in the present application can slow down the speed or acceleration of the outward expansion of the load-bearing platform 4, and reduce the impact force on the connecting parts during the expansion of the load-bearing platform 4.

[0154] It can be seen from the above technical solution that the present application achieves the purpose of reducing the unfolding speed of the carrying platform 4 by setting 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 adopts a release part 430 set in the fixed frame 1 to slow down the movement of the running part 420, thereby ensuring the safety and stability of the unfolding process of the carrying platform 4.

The closed state refers to a state in which the supporting platform 4 is completely located inside the fixed frame 1, and the unfolded state includes a state in which the supporting platform 4 has just rotated relative to the fixed frame 1 and started to unfold outward, and also includes a state in which the supporting platform 4 rotates outward to be perpendicular to the fixed frame 1.

In practical applications, when the platform is deployed, if it is affected by strong wind resistance, it may be difficult to deploy the platform, which affects the trapped people to reach the platform as soon as possible for shelter. In this embodiment, the stopper 480 can be used to prevent the supporting platform 4 from rotating in the opposite direction when it is deployed outward, thereby increasing the deployment speed of the supporting platform 4.
