[0097] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0098] Escape platforms are not yet included in current buildings. In the event of a dangerous situation, each floor should have an openable platform that forms an escape route on the exterior wall. Current buildings have casement, sliding, top-hung, and bottom-hung windows for lighting and ventilation, but these windows have small opening sections and small opening areas, and when opened, they cannot form a platform for people to gather, thus reducing the chances and efficiency of escape.

[0099] Escape platforms are set up on each floor in locations that facilitate escape. When closed, the platforms can function as part of the building itself and can also be used to provide lighting, ventilation, and smoke extraction. When opened, they form a platform on the building facade with a certain load-bearing capacity, allowing people to gather on them to await rescue or use a descent device to descend to a safe location and escape danger.

[0100] The specific structure of the escape platform provided in this application will be described in detail below with reference to the accompanying drawings.

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

[0102] The supporting 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 inside the opening of the building. The supporting platform 4 can be a high-strength transparent window. The bottom end of the supporting platform 4 is hinged to the inner wall of the bottom end of the fixed frame 1.

[0103] When the support platform 4 is in the closed state, the support platform 4 is snapped into the fixed frame 1 to seal the opening, and the building can be lit and insulated normally.

[0104] With the support platform 4 in the open state, the support platform 4 rotates outwards to the outside of the building facade, and the support platform 4 can reach a horizontal state to form a platform for escapers to stay on. Escapers stand on the support platform 4, located outside the building, away from the fire inside the building. Escapers can gather on it to wait for rescue or use the descent device to descend to a safe location to escape danger.

[0105] In some embodiments, a first sealing body 440 is provided inside the four sides of the support platform 4. When the support platform 4 is in the closed state, the first sealing body 440 is squeezed and sealed with a second sealing body 110 provided inside the fixed frame 1. A guardrail 6 is provided on the support platform 4. The guardrail 6 is located at the edge of the support platform 4 and is foldably hidden in the first receiving space 111 of the two side frames 11 of the fixed frame 1, and foldably hidden in the second receiving space 112 of the upper frame of the fixed frame.

[0106] Reference Figure 1 As shown, in some embodiments, a diagonal bracing member 5 is also included. The diagonal bracing member 5 is disposed between the two sides of the bearing platform 4 and the two side frames of the fixed frame 1, and the diagonal bracing member 5 is hidden in the first receiving space of the two side frames of the fixed frame 1.

[0107] With the support platform 4 in the closed state, the inclined pull component 5 is hidden in the first receiving space of the two side frames of the fixed frame 1;

[0108] With the load-bearing platform 4 in the open state, the inclined tie member 5 extends between the load-bearing platform 4 and the fixed frame 1 to increase the load-bearing capacity of the load-bearing platform 4.

[0109] To ensure the safety of those escaping, the support platform 4 forms a cantilever structure with the wall after it is opened. The higher the escape opening is set and the longer the cantilever of the cantilever structure, the less favorable it is for the support platform 4 to bear the load. Therefore, after the support platform 4 is opened, inclined tie members 5 are provided on both sides of the fixed frame 1 to connect with the support platform 4, so as to enhance the load-bearing strength of the support platform 4.

[0110] The inclined pull component 5 can be a rod-like structure with a limiting device, which allows the inclined pull component 5 to move in a specified direction when the bearing platform 4 returns to the closed state, and to be located within the first accommodating space provided by the bearing platform 4 or the fixed frame 1. The inclined pull component 5 can also be a telescopic component, which extends or retracts to a set position in a set direction when the bearing platform 4 is open, and is located within the accommodating space of the bearing platform 4 or the fixed frame 1 when the bearing platform 4 returns to the closed state. The inclined pull component 5 can also be a rope or chain-like component, which extends to a set position and stops moving when the bearing platform 4 is in the open state. One end of the rope or chain-like component can be provided with a counterweight structure or friction structure to enable the bearing platform 4 to open slowly.

[0111] Reference Figure 2 As shown, 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 opens and completes the escape mission, the various functions and components of the carrying platform 4 are checked. If the various functions and components of the carrying platform 4 are found to be undamaged, the recovery device 3 can be used to manually restore the carrying platform 4 to the closed state from the indoor side. The platform is then locked by 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.

[0112] Specifically, a rope-like component can be used to connect the recovery device 3 and the support platform 4. One end of the rope-like component is connected to the support platform 4, and the other end is connected to the rope wheel of the recovery device 3. The rope wheel is controlled by the unidirectional movement principle of the pawl. A tool corresponding to the pawl can be used to rotate the rope wheel, causing the rope-like component to wrap around the rope wheel and pull the support platform 4 back to its initial state. Alternatively, a chain-like component can be used. The chain cooperates with the sprocket. By rotating the sprocket, the chain is contracted. The contracted chain enters the set receiving space, pulling the support platform 4 back to its initial closed state and locking it. Alternatively, a screw structure can be used to achieve recovery. Rotating the screw causes the screw nut connected to the screw to move linearly. The screw nut rope-like component, chain component, or connecting rod component is connected to the escape platform. The screw nut moves in a 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 also included, the manual switch 2 comprising:

[0114] The operating unit 210 is used to enable the trapped person to manually unlock the escape platform. Therefore, it can be set on the side of the fixed frame 1 facing the room. When the trapped person is affected by the fire, he / she can manually operate the operating unit 210 to unfold the escape platform. The specific form of the operating unit 210 is not limited to a handle, handle, or joystick. The shape and arrangement of the operating unit 210 should be conducive to the operator to apply force so as to unfold the operating platform as soon as possible.

[0115] An execution unit 220 is connected to the operation unit 210 and is movably connected to the fixed frame 1. One end of the execution unit 220 is connected to the operation unit 210, and the other end can be located inside, on, or outside the fixed frame 1. The operation unit 210 is configured to move along a first direction so as to drive the other end of the execution unit 220 to move along the first direction.

[0116] There are multiple ways to connect the actuator 220 and the fixed frame 1. For example, in some embodiments, the actuator 220 can be slidably connected to the fixed frame 1. In this case, the first direction is the direction of sliding, which corresponds to the direction in which the operator holds the actuator 210 closer to or further away from the fixed frame 1. In other embodiments, the actuator 220 can also be rotatably connected to the fixed frame 1, that is, the first direction is rotation in the upward, downward or other arbitrary directions.

[0117] In this application, the function of the actuator 220 can be to directly transmit the operator's force to the push-out part 240 in a predetermined direction, that is, to push the push-out part 240 in the second direction to push the support platform to unfold to the outside side in the second direction; the function of the actuator 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 push-out part in the second direction, forming an auxiliary pushing effect on the push-out part 240, thereby realizing the unlocking of the support platform 4 and the fixed frame 1.

[0118] Depend on Figure 4 It is understood that the device also includes an unlocking part 230 and an ejection part 240 disposed inside the fixed frame 1; the ejection part 240 is movably engaged with the support platform 4; wherein, the unlocking part 230 has a controlled end (force input position) and an actuating end (force output position) according to the direction of force transmission, the controlled end is connected to the end of the actuating part 220 away from the operating part 210, and the actuating end of the unlocking part 230 is connected to the ejection part 240; the end of the ejection part 240 is a structure that can be engaged with the support platform 4. It should be considered that its end can be directly engaged with the support platform 4, or it can also be engaged with a fixed structure fixed to the support platform 4 (e.g., Figure 4The embodiment shown is provided with a hook-like structure on the support platform 4; the unlocking part 230 is configured to push the push-out part 240 in the second direction when the other end of the execution part 220 moves in the first direction, so as to unlock the support platform 4 and the fixed frame 1.

[0119] In some embodiments, the ejection part 240 may be omitted, and the execution end of the unlocking part 230 may be directly engaged with the support platform 4, thereby unlocking the support platform 4 and the fixed frame 1 through the unlocking part 230. Therefore, in this embodiment, the execution part 220 can simultaneously control the ejection part 240 and / or the unlocking part 230 to achieve the unlocking operation.

[0120] It should be noted that in this embodiment, the snap-fit ​​structure between the push-out part 240 and the support platform 4 is not limited to one set. For example, multiple push-out parts 240 can be evenly distributed within the unfolded surface of the support platform 4, and multiple push-out parts 240 can be driven by the unlocking part 230 at the same time. Then, multiple fixing structures that snap-fit ​​with the push-out parts 240 are correspondingly provided on the support platform 4, thereby increasing the stability and structural strength when snap-fit ​​is locked.

[0121] In some embodiments, a protective structure is also included;

[0122] The manual switch 2 is equipped with a protective structure. Under normal circumstances, the manual switch 2 is sealed inside the protective structure to prevent accidental contact. 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 also included on the support platform, the guardrail 6 comprising:

[0124] The handrail part 610 is a rod-shaped structure. The handrail part 610 is connected to the guardrail lifting device. When the support platform 4 rotates away from the room, the handrail part 610 is lifted by the guardrail lifting device until the support platform 4 is perpendicular to the fixed frame 1, and the distance between the handrail part 610 and the support platform 4 reaches a preset value.

[0125] The support part 620 is located between the handrail part 610 and the support platform 4; it enables the guardrail 6 to be folded into the receiving space of the fixed frame 1 and can prevent the risk of escapers falling from the support platform 4.

[0126] The fixing part is slidably connected within the receiving space of the fixing frame 1, and the two ends of the fixing part are rotatably connected to the handrail part 610. When the distance between the supporting platform 4 and the handrail part 610 reaches a preset value, the supporting part, handrail part, and supporting platform self-lock. A self-locking structure is provided between the supporting part, handrail part, and supporting platform. When the distance between the supporting platform 4 and the handrail part 610 reaches the preset value, the supporting part 620 unfolds and locks, preventing escapees on the supporting platform 4 from pressing the upper handrail part 610 of the guardrail 6, causing the guardrail 6 to change from an unfolded state to a folded state, thus preventing the escapee from falling off the guardrail 6.

[0127] When the support platform 4 is opened, the guardrail 6, which is folded and hidden in the space of the fixed frame 1, also opens. When the support 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 escape personnel on the support platform 4 from pressing the upper handrail 610 of the guardrail 6, causing the guardrail 6 to change from the unfolded state to the folded state, thereby causing the escape personnel to fall from the guardrail 6.

[0128] In some embodiments, the guardrail 6 is connected to 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 near the fixed frame 1 are slidably connected to the fixed frame 1; wherein, the guardrail 6 may be connected to an accommodating space provided inside or outside the fixed frame 1, which is not limited here; when the escaped personnel are on the support platform 4, the guardrail 6 is used to provide protection to prevent the escaped personnel from falling off the support platform 4;

[0129] The escape platform also includes a guardrail lifting device, which includes a lifting part 630. The lifting part 630 is disposed within the fixed frame 1 or between the support platform 4 and the fixed frame 1. When the support platform 4 moves in a first direction, the guardrail 6 moves along a second direction via the lifting part 630 to achieve a preset distance between the guardrail 6 and the support platform 4. The first direction is the direction away from the interior; the second direction is the direction in which the guardrail 6 unfolds, i.e., the direction away from the support platform 4.

[0130] The guardrail lifting device provided in this application allows the guardrails 6 surrounding the support platform 4 to rise simultaneously during the opening process of the support platform 4. When the guardrails 6 rise, the lifting part 630 can lift them to a set position using the gravity of the support platform 4 during opening. Figure 8 As shown, when the guardrail 6 is raised, its trajectory can be restricted by the guide components. When the support platform 4 is opened to the set position, the guardrail 6 is raised to the set position by the escape platform guardrail raising device and self-locks, as shown. Figure 9 As shown, it provides protection for escapees on the carrying platform 4, thereby improving the safety of escapees when they are on the carrying platform 4.

[0131] Reference Figures 8-10 As shown, in some embodiments, a fireproof and heat-insulating curtain 9 is also included, the fireproof and heat-insulating curtain 9 comprising;

[0132] The shape of the frame 910 is not limited, but since 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, with the outer contour of the frame 910 matching the inner contour of the opening, and the frame 910 is fixed inside 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 inside the fixed frame 1.

[0133] 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 that communicates with the receiving cavity 911. The outlet 912 can be a long strip opening and the outlet 912 is vertically downward.

[0134] A winding mechanism 920 is provided on the frame 910, and the winding part of the winding mechanism 920 is located inside the receiving cavity 911; a fireproof roller shutter 930 is provided inside the receiving cavity 911, the inner end of the fireproof roller shutter 930 is connected to the winding part of the winding mechanism 920, and the outer end of the fireproof roller shutter 930 passes through the outlet 912 and extends to the outside of the receiving cavity 911; a movable frame 940 is connected to the outer end of the fireproof roller shutter 930, the movable frame 940 can be a cuboid frame, and the length of the movable frame 940 matches the inner contour width of the frame 910;

[0135] The locking mechanism 950 for fixing the fireproof roller shutter 930 includes a first locking part and a second locking part. The first locking part is disposed on the bottom inner wall or the bottom of the side wall of the frame 910, and the second locking part is disposed on the movable frame 940.

[0136] When the fireproof roller shutter 930 moves downward to the fully closed state, the first locking part and the second locking part engage, preventing the fireproof roller shutter 930 from moving upward. This keeps the fireproof roller shutter 930 in the closed state, stably blocking indoor smoke and open flames, and ensuring the safety of escaping personnel.

[0137] Reference Figure 11 and Figure 12 As shown, in some embodiments, a descent device 7 is also included, which includes a fixed base 710, a rotating shaft 720, a cable assembly 730, a friction part 740, and a damping mechanism 750.

[0138] like Figure 12 As shown, the fixing base 710 can be a metal connecting base, which includes a horizontally arranged fixing plate and a vertically arranged connecting plate. The fixing plate can be fixed to the bearing platform, the fixing frame or the building facade, and multiple connecting plates are vertically arranged on the fixing plate.

[0139] The rotating shaft 720 passes through multiple fixed plates of the fixed base 710 and is rotatably connected to the fixed base 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 fixed base 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, which can be a clockwise rotational motion.

[0140] The damping mechanism 750 is disposed between the friction part 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 slides and rubs against the friction part 740. The frictional force applies a reverse force to the damping mechanism 750 and the rotating shaft 720 to resist the first rotational motion, thereby reducing the rotational speed of the rotating shaft 720, reducing the release speed of the cable assembly 730, and thus reducing the descent speed of the escapee, so as to avoid injury to the escapee due to excessive descent speed.

[0142] The descent device provided in this application has a fixed base 710 that can be installed on a support platform or fixed frame, or it can be installed on the building facade and is in a fixed state. When using this descent device, there is no need to find a safe attachment point or support indoors, making it convenient to use. During escape, the user descends via a 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 slides and rubs against the friction part 740. The frictional force applies a reverse force to the damping mechanism 750 and the rotating shaft 720 to resist the first rotational motion, thereby reducing the rotational speed of the rotating shaft 720, reducing the release speed of the cable assembly 730, and thus reducing the descent speed of the escapee, allowing the escapee to descend slowly and achieve a safe and rapid descent escape.

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

[0144] The turntable is fitted onto 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, which is wound around the turntable, and the outer end of the cable is equipped with a connecting ring.

[0146] As the people escaping descend via the cable, the cable causes the turntable and shaft to rotate for the first time.

[0147] The damping mechanism 750 includes a first guide 751 and a friction block 752;

[0148] The first guide member 751 can be a rod, and there can be a plurality of first guide members 751. Preferably, the plurality of first guide members 751 are evenly distributed around the rotating shaft. The first guide members 751 are connected to the rotating shaft, and the extension direction of the first guide members 751 is perpendicular to the axial direction of the rotating shaft. The outer end of the first guide member 751 extends toward the friction part. The friction block 752 can be a ring, and the outer end of the friction block 752 is a friction surface. The friction block 752 is sleeved on the first guide member 751. The distance between the outer end of the first guide member 751 and the inner wall of the friction part 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 751 and the friction block 752 to rotate synchronously. The outer wall of the friction block 752 velocities with the inner wall of the friction part. As the descent speed of the escaped person increases, the rotation speed of the turntable and the rotating shaft increases, the relative speed between 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 velocities between the two increase. This, in turn, increases the reverse force on the friction block 752 that resists the first rotational motion, thereby reducing the rotation speed of the rotating shaft and the turntable, and thus reducing the descent speed of the escaped person, preventing injury caused by the escaped person descending too quickly.

[0150] Reference Figure 13 and Figure 14 As shown, in some embodiments, a platform sustained-release device is also included, the platform sustained-release device comprising;

[0151] The third connecting part 410; one end of the third connecting part 410 is connected to the movable end of the bearing platform 4; wherein, the movable end of the bearing platform 4 refers to the end away from the hinge position with the fixed frame, that is, the end that unfolds outward; as the bearing platform 4 unfolds outward, it will pull the third connecting part 410 outward along the unfolding direction. For the third connecting part 410, it will move in angle and length due to the pull of the bearing platform 4, thereby driving the running part 420 at the other end to make corresponding movements.

[0152] The running part 420 is linked to the third connecting part 410. The running part 420 is configured such that when the movable end of the bearing platform 4 opens to the outside, 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 curve. It should be noted that in this embodiment, the linkage between the third connecting part 410 and the running part 420 can take many forms. For example, when the third connecting part 410 is a rope-like cable and the running part 420 is a turntable or roller, when the third connecting part 410 is pulled, it can drive the running part 420 to rotate. Therefore, the simultaneous pulling and rotation are called linkage. It should be understood that when the third connecting part 410 and the running part 420 are different structures, the linkage between them can be different. In this application, one such example is given. In this case, the third connecting part 410 can drive the running part 420 to perform the first movement.

[0153] A release unit 430, located within the fixed frame 1, is configured to apply a counterforce to the running unit 420 to impede the first movement. In this application, the release unit 430 can be positioned anywhere within the fixed frame 1, such as on the upper side, side, or bottom. Depending on its position, the release unit 430 can also be configured with different structures. When the release unit 430 provides a counterforce to the running unit 420 to impede the first movement, it slows down the speed of the first movement. Simultaneously, due to the linkage between the running unit 420 and the third connecting part 410, it also slows down the speed at which the third connecting part 410 is pulled out. Therefore, by providing the release unit 430, this application can slow down the speed or acceleration of the outward unfolding of the support platform 4, reducing the impact force on the connecting components during the unfolding of the support platform 4.

[0154] As can be seen from the above technical solution, this application sets up a third connecting part 410 connected to the support platform 4 and a running part 420 that is linked to the third connecting part 410. At the same time, it uses a slow-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 support platform 4 and ensuring the safety and stability of the deployment process of the support platform 4.

[0155] Reference Figure 15 and Figure 16 As shown, in some embodiments, a platform frame connection structure is also included, the platform frame connection structure including;

[0156] First connecting part 450; the first connecting part 450 is fixed to the bottom of the fixed frame 1 and to the side closer to the outside;

[0157] A second connecting part 460 is rotatably connected to the first connecting part 450 via a rotating part 470; the second connecting part 460 is fixedly connected to the side of the bearing platform 4 near the outdoors; in this embodiment, the first connecting part 450 and the second connecting part 460 can be in the shape of a strip, a steel bar, or other shapes, and should be considered as components that provide a connecting function. By rotating the first connecting part 450 and the second connecting part 460 relative to each other, the opening and closing states between the bearing platform 4 and the fixed frame 1 can be switched. The opening and closing states include a closed state and an unfolded state. The closed state refers to the state in which the bearing platform 4 is completely located inside the fixed frame 1. The unfolded state includes the state in which the bearing platform 4 has just rotated relative to the fixed frame 1 and has begun to unfold outward, and also includes the state in which the bearing platform 4 rotates outward to be perpendicular to the fixed frame 1.

[0158] The second connecting part 460 is used to drive the bearing platform 4 to rotate in the first direction; the first direction is the direction in which the bearing platform 4 unfolds from the closed state to the outside.

[0159] The platform frame connection structure also includes a stop 480 connected between the first connecting part 450 and the second connecting part 460. The stop 480 is used to prevent the platform 4 from rotating in a second direction, which is the opposite of the first direction. In practical applications, if the platform is affected by strong wind resistance when it is deployed, it may be difficult to deploy the platform, affecting the ability of trapped personnel to reach the platform for safety as quickly as possible. In this embodiment, the stop 480 can prevent the platform 4 from rotating in the opposite direction when it is deployed outward, thereby increasing the deployment speed of the platform 4.

The first fixing part 140 includes, but is not limited to, expansion bolts, bolts, and screws. This application uses a pre-embedded part 120 to be pre-embedded around the opening of the building facade, and a frame part 130 is set on the outside of the opening of the building facade and fixedly connected to the pre-embedded part 120 and the fixed frame 1 through the first fixing part 140, thereby strengthening the connection strength between the fixed frame 1 and the building facade, thereby enhancing the connection strength of the bearing platform 4, so that when the escaped personnel are stranded on the bearing platform 4, the bearing platform 4 has a certain bearing capacity and stability, and the bearing platform 4 can still remain stable in windy weather;

[0162] One side of the subframe 130 is connected to the embedded part 120 via the first fixing part 140, and the other side is located on the side of the building facade opening near the interior. For example, the subframe 130 can be an L-shaped structure, with one side located on the side of the building facade opening near the interior to support the platform 4 when it is opened, thereby reducing the shear force on the fixing frame 1 and the opening fixing components and further improving the stability between the fixing frame 1 and the building facade.

[0168] The support portion 820 may be a rod-shaped structure. The support portion 820 is movably connected to the fixing portion 810. One end of the support portion 820 is rotatably connected to the fixing portion 810, and the other end can rotate in the first direction until the other end of the support portion moves to the outside of the hidden cavity. A plurality of connecting members 830 are provided on the support portion 820.

[0169] The support part 820 can rotate freely. When in use, the support part 820 rotates in the first direction until the outer end of the support part 820 moves to the outside of the hidden cavity and reaches the set position. At this time, the user can slowly lower it through the connector 830.

[0170] When not in use, the support 820 can drive the connector 830 to rotate and completely enter the hidden cavity, thereby hiding and storing it to avoid damage and improve aesthetics.

[0173] When the support platform 4 is opened, the support platform 4 drives the moving part 170 to move in the first direction, and the second locking part 171 is slidably connected to the first locking part 161; when the support 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 locking part 171 is locked to the first locking part 161 to prevent the support platform 4 from moving in the second direction, that is, to prevent the support platform 4 from moving in the opposite direction, thereby ensuring that the support platform 4 opens quickly and buys escape time for the escapees.
