DETAILED DESCRIPTION

[0063] The escape platform is arranged to form a platform structure for escaping on the outer wall surface of the building when a dangerous situation occurs. The existing building is usually provided with flat-open, sliding, upper-suspended and lower-suspended windows for lighting and ventilation, but due to the small opening and small opening area of the window sash, the opened window cannot form a platform for people to gather, which greatly reduces the escape probability of the trapped person.

[0064] The escape platform according to the present application can be arranged at a position convenient for escaping on each floor of the building, and the platform can be used as a part of the building when closed, and can also be used to realize the functions of lighting, ventilation and smoke exhaust of the window; when opened, a platform is formed on the outer facade of the building, which has a certain bearing capacity, and the escaping personnel can gather on the platform to wait for rescue, or use the slow descent device to descend to a safe position to escape from danger.

[0065] As Figures 1 to 7The escape platform provided by the embodiment of the application is installed on the opening of the building, and meanwhile, the position of the escape platform needs to be ensured to meet the requirements of the facade effect of the building. The escape platform comprises a bearing platform 4 and a fixed frame 1. The fixed frame 1 is arranged on the opening of the building wall, and the bearing platform 4 is movably connected with the fixed frame 1. The fixed frame 1 arranged on one side of the indoor side is provided with a manual switch 2. The manual switch 2 is provided with a protection structure 21. In a normal case, the manual switch 2 is sealed in the protection structure 21 to avoid being accidentally touched. When in use, the protection structure 21 is opened or removed, and then the manual switch 2 can be operated.

[0066] The first sealing body 41 is arranged in the four side frames of the bearing platform 4. When the bearing platform 4 is in a closed state, the first sealing body 41 is extruded and sealed with the second sealing body 12 arranged on the inner side of the fixed frame 1. The guardrail 6 is arranged on the bearing platform 4 and is arranged at the edge of the bearing platform 4. The guardrail 6 is foldably hidden in the first containing space 111 of the two side frames 11 of the fixed frame 1 and is foldably hidden in the second containing space 112 of the upper frame of the fixed frame.

[0067] The inclined pulling component 5 is arranged between the two side frames of the bearing platform 4 and the two side frames 11 of the fixed frame 1, and the inclined pulling component 5 is hidden in the first containing space 111 of the two side frames 11 of the fixed frame 1. The first locking part 42 is arranged on the side frame of the bearing platform 4, and the first locking part 42 and the second locking part 13 arranged on the side frame of the fixed frame form a locked state.

[0068] After the bearing platform 4 is opened through the manual switch 2, the bearing platform 4 is connected with the lower frame of the fixed frame 1, so that the bearing platform 4 is rotated and opened to a set position outside the room. Specifically, the connection and rotation can be realized through the hinge structure 131. When the bearing platform 4 is in an open state, the personnel need to gather on the bearing platform 4 when escaping, and the bearing platform 4 should have a certain bearing capacity.

[0069] In order to ensure the safety of the escaping personnel, the bearing platform 4 forms a cantilever structure with the wall after being opened. The higher the escape opening is arranged and the longer the cantilever of the cantilever structure is, the more difficult it is for the bearing platform 4 to bear. Therefore, the inclined pulling component 5 connected with the bearing platform 4 is arranged on both sides of the fixed frame 1 after the bearing platform 4 is opened, so as to enhance the bearing strength of the bearing platform 4.

[0070] The inclined pulling component 5 can be a rod structure and is provided with a limiting device, so that the inclined pulling component 5 is moved to a specified direction and is located in a first containing space of the bearing platform 4 or the fixed frame 1 when the bearing platform 4 is restored to the closed state. The inclined pulling component 5 can also be a telescopic component, which is extended or retracted to a specified position in a specified direction when the bearing platform 4 is opened, and is located in a containing space of the bearing platform 4 or the fixed frame 1 when the bearing platform 4 is restored to the closed state. The inclined pulling component 5 can also be a rope or chain component, which is extended to a specified position and stops moving when the bearing platform 4 is opened, and one end of the rope or chain component is provided with a counterweight structure or a friction structure, so that the bearing platform 4 is slowly opened.

[0071] At this time, the bearing platform 4 has the escape function, but in order to ensure that the escape personnel on the bearing platform 4 do not fall, the side of the bearing platform 4 which is not connected with the wall body can be provided with a guardrail 6 which is automatically raised when the bearing platform 4 is opened, so as to improve the safety of the bearing platform 4. A spring pneumatic telescopic device is arranged between the bearing platform 4 and the guardrail 6, and under the action of the pulling force or the pushing force of the spring pneumatic telescopic device, the guardrail 6 is raised to a specified height and is locked, and a gap for the escape personnel is arranged at the position of the guardrail of the bearing platform, so that the escape personnel can safely escape through the gap after wearing the escape equipment, without climbing over the guardrail to escape. The number and position of the gap can be set according to the use.

[0072] The fixed frame 1 is also provided with a connecting part 8 of the backpack type slow descending device, the escape personnel wears the slow descending device, the slow descending rope of the slow descending device is connected with the connecting part 8, and the slow descending device is raised and lowered through the slow descending rope. Specifically, after the escape personnel wears the slow descending device, the connecting end of the slow descending rope is connected with the connecting end of the connecting part 8, in the actual use process, the slow descending device is slowly descended under a certain gravity through a friction part, the slow descending rope is stored in a winch connected with the friction part, the whole component is installed in the backpack, the connecting end of the slow descending rope is extended out of the backpack and is connected with the connecting part 8 arranged on the fixed frame 1, the escape personnel can escape after the slow descending device is fixed on the body through the safety belt, the friction force of the friction part can be adjusted, and the adjustment of the friction force can change the descending speed; the slow descending device can be provided with a descending stopping device, the descending stopping device is manually controlled, the descending stopping device can press the friction part through a pressing structure to increase the friction force, and the descending is stopped when the friction force is greater than the gravity; or the descending stopping device can press the slow descending rope through the pressing structure to increase the friction force, and the descending is stopped when the friction force is greater than the gravity.

[0073] The escape platform is also provided with a restoring device 3 arranged on the fixed frame 1. After the carrying platform 4 completes the escape task, the functions and components of the carrying platform 4 are checked. If the functions and components of the carrying platform 4 are not damaged, the carrying platform 4 can be manually restored to the closed state from the indoor side by using the restoring device 3, and is locked by the locking structure arranged on the fixed frame 1 and the carrying platform 4. After the carrying platform 4 is restored to the initial state, the carrying platform 4 can be repeatedly used.

[0074] Specifically, a rope component can be used to connect the restoring device 3 and the carrying platform 4. One end of the rope component is connected to the carrying platform 4, and the other end is connected to a rope wheel of the restoring device 3. The rope wheel is controlled by the one-way movement principle of the pawl. A tool corresponding to the pawl is used to rotate the rope wheel, so that the rope component is wound on the rope wheel, and the carrying platform 4 is restored to the initial state. A chain component can also be used. The chain is matched with a chain wheel. The chain is retracted by rotating the chain wheel. The retracted chain enters the accommodating space, and the carrying platform 4 is restored to the initial state and locked. A lead screw structure can also be used to restore. The rotation of the lead screw makes the nut connected to the lead screw move linearly. The nut rope component, chain component or connecting rod component is linked with the escape platform. The nut moves in the set direction to restore the escape platform to the initial state and lock.

[0075] The escape platform can also be provided with a slow descent device 7, and the escape is realized by the slow descent device 7. When used, the escape personnel need to wear an escape safety harness. After wearing the safety harness, the safety harness is connected to the slow descent cable 71 of the slow descent device 7, and can be slowly descended to a safe position or the ground for escape. The slow descent device 7 is arranged on the indoor side wall, and the number thereof can be set to be multiple. The connection end for connecting with the safety harness worn by the escape personnel extends out of the outdoor side, so that the escape personnel can quickly escape after wearing the safety harness and connecting with the connection end of the slow descent device.

[0076] The slow descent device 7 can also be arranged on the fixed frame 1, and the number thereof can be set to be multiple. The connection end 72 of the slow descent device 7 arranged on the fixed frame 1 also extends out of the outdoor side, so as to facilitate the escape personnel to quickly escape.

[0077] The slow descent device 7 can also be arranged separately from the bearing platform 4, for example, a first connecting part and a third locking part connected with the slow descent device 7 are arranged on the fixed frame 1 or the bearing platform 4, and the number of the first connecting part and the third locking part is at least one. After the bearing platform 4 is opened, the escape personnel fix the slow descent device 7 to the first connecting part, and lock through the third locking part. After the escape personnel wear the safety harness, the safety harness will be connected with the connecting end 72 of the slow descent device. It needs to be explained that the number of the above-mentioned first connecting part and the third locking part is multiple. In the actual use process, it is not necessary to use multiple first connecting parts and third locking parts at the same time to realize the escape function. One escape or one escape personnel only needs to use a pair of first connecting part and third locking part. The multiple first connecting part and third locking part is arranged on one hand to facilitate the escape personnel to fix the safety harness, and on the other hand to facilitate multiple escape personnel to escape at the same time.

[0078] The slow descent device 7 can also be arranged as a reciprocating structure, for example, each slow descent device 7 is provided with two second connecting parts, and the two second connecting parts cannot be used at the same time. When escaping, the first escape personnel first uses one of the second connecting parts to descend to the safe position or the ground, and then takes off the escape harness. At this time, the second escape personnel on the bearing platform 4 can use the other second connecting part to descend. When the second escape personnel descends, the connecting end 72 used by the first escape personnel with the escape harness is recycled to the initial position on the bearing platform 4, and can be used again by the escape personnel. In this way, in the subsequent escape process of the escape personnel, repeated fixing work is not needed. After wearing the escape harness, the escape personnel can quickly escape from the dangerous environment.

[0079] The escape platform can also be provided with a fireproof heat insulation curtain 9. The fireproof heat insulation curtain 9 is arranged on the indoor side of the upper edge frame of the fixed frame 1. The guide part of the fireproof heat insulation curtain 9 is arranged on the indoor side of the side edge frame 11 of the fixed frame 1. After the escape personnel reaches the bearing platform 4, the fireproof heat insulation curtain 9 can be manually pulled down, so as to form a partition seal between the bearing platform 4 and the indoor side of the building. At this time, if there are still personnel who have not escaped to the bearing platform 4 in the room, the fireproof heat insulation curtain 9 can also be opened from the indoor side. After reaching the bearing platform 4, the fireproof heat insulation curtain 9 is closed again to form a partition layer, so that the space of the bearing platform 4 is safer, so as to gain more escape time.

[0080] The fireproof heat insulation curtain 9 is rotated and contracted under the shaft of the containing space by the spring force. When the downward pulling force is greater than the spring force, the heat insulation curtain runs downward along the two side guide parts to the set position. The set position is provided with a locking structure. The locking structure can be opened from the indoor side and the outdoor side, so that the personnel who have not escaped to the escape platform can continue to hide and escape.

[0081] It should be noted that the escape platform escape hanging point device provided by the embodiments of the present application can also be used alone and is not limited to the building scene, but also to other scenes with height difference, for example, tower crane, high mountain, bridge, mine or ship scene.

[0082] Based on the foregoing technical solution, the personnel evacuated to the escape platform can escape through the escape backpack slow descent device, but one end of the slow descent device cable needs to be fixed by a solid and reliable support device to meet the use conditions of the escape device. The existing escape device lacks a stable hanging point device, which makes the slow descent device inconvenient to use. The present application provides an escape platform escape hanging point device to solve the foregoing problems.

[0083] Referring to Figures 8 to 11 , the present application provides an escape platform escape hanging point device, i.e. the connection part 8 described above, applied to an escape platform including a bearing platform 4 and a fixed frame 1, the hanging point device specifically including a fixed part 810, a supporting part 820 and a connecting piece 830;

[0084] The fixed part 810 can be a fixed plate, and the fixed part 810 is fixed to the fixed frame or the facade of the building. One end of the supporting part 820 is connected to the fixed part 810, and the other end of the supporting part is located at a set position. The connecting piece 830 is connected to the supporting part 820.

[0085] As Figure 8 shown, the connecting piece 830 can be a hanging ring, and the connecting piece 830 is used to fix the cable of the escape equipment;

[0086] As Figure 9 shown, Figure 9 A is an escape slow descent device provided by the escape platform, and the connecting piece 830 is a connecting part of the escape slow descent device A.

[0087] As Figure 8 shown, a hidden cavity is provided in the fixed frame 1 or the wall of the building, and the hidden cavity can be a rectangular cavity or other shaped cavity. The fixed part 810 can be directly fixedly connected with the inner wall of the hidden cavity, or can be fixed in the hidden cavity through other fixing pieces;

[0088] The supporting part 820 can be a rod-shaped structure, and the supporting part 820 is movably connected with the fixed part 810. One end of the supporting part 820 is rotatably connected with the fixed part 810, and the other end can be rotated in a first direction until the other end of the supporting part moves to the outside of the hidden cavity. A plurality of connecting pieces 830 are arranged on the supporting part 820;

[0089] The supporting part 820 can be freely rotated. When in use, the supporting part 820 is rotated in the first direction until the outer end of the supporting part 820 moves to the outside of the hidden cavity and reaches a set position. At this time, the user can slow down through the connecting piece 830;

[0090] When not in use, the supporting part 820 can drive the connecting part 830 to rotate and completely enter the hidden cavity, thereby hiding the storage, avoiding damage, and improving the aesthetic appearance.

[0091] As shown in Figure 10 In order to facilitate installation and arrangement, the fixed part 810 is fixedly arranged on the fixed frame 1 or the facade of the building; the supporting part 820 is fixedly connected with the fixed part 810, one end of the supporting part 820 is connected with the fixed part 810, and the other end of the supporting part 820 extends to the outdoor side of the building; the connecting part 830 is connected with the supporting part 820.

[0092] The above-mentioned hanging point device is a fixed hanging point device, which is exposed outside the escape platform and has the advantages of being easy to find and stable structure.

[0093] Further, in an embodiment, the hanging point device further comprises a protection part 840.

[0094] The protection part 840 can be a protection plate or a baffle, and the protection part 840 is arranged on the fixed frame 1 or the wall of the building. The fixed frame 1 or the building can be provided with a slide, and the protection part 840 is slidably connected with the slide. When the supporting part 820 and the connecting part 830 are stored in the hidden cavity, the protection part 840 slides to the first direction of the slide until it completely covers the hidden cavity, thereby hiding the supporting part 820 and the connecting part 830. When the hanging point device is used for escape, the protection part 840 slides to the second direction of the slide to completely open the hidden cavity, the supporting part 820 rotates along the first direction until the other end of the supporting part and the connecting part 830 move to the outside of the hidden cavity, and the connecting part 830 is connected with the cable of the escape equipment, so that the escape can be quickly realized.

[0095] Further, in an embodiment, when the fixed part 810 is connected with the wall of the building, in order to improve the stability of the fixed part 810, the hanging point device further comprises a pre-embedded part 850.

[0096] The pre-embedded part 850 can be a pre-embedded nail, and the pre-embedded part 850 is arranged in the wall of the building. One end of the fixed part 810 is fixedly connected with the pre-embedded part 850, and the other end of the fixed part 810 penetrates the wall and is connected with the supporting part 820.

[0097] Alternatively, the pre-embedded part 850 is fixedly connected with the fixed part 810 and arranged in the wall of the building. One end of the supporting part 820 is connected with the fixed part 810, and the other end of the supporting part 820 penetrates the wall, thereby stably fixing the fixed part 810.

[0098] In actual application, the fixed part 810, the supporting part 820 and the connecting part 830 can have various structural forms, and the following will be specifically described by taking several realizable modes as examples.

[0099] As shown in Figure 8As shown, in one embodiment, the side wall of the fixing part 810 is provided with a first sliding groove 811;

[0100] The support portion 820 includes a first mounting portion 821, a limiting portion 822, and a connecting rod 823. Both the first mounting portion 821 and the limiting portion 822 can be rods. The connecting member 830 is disposed on the first mounting portion 821. One end of the limiting portion 822 is fixedly connected to the end of the first mounting portion 821, and the extension direction of the first mounting portion 821 and the extension direction of the limiting portion 822 form an angle. The first mounting portion 821 and the limiting portion 822 can form a 90° angle. The other end of the limiting portion 822 is rotatably connected to the fixing portion 810. One end of the connecting rod 823 is rotatably connected to the first mounting portion 821, and the other end of the connecting rod 823 is slidably connected to the first slide groove 811 through a slider.

[0101] like Figure 11 As shown, the first mounting part 821 and the limiting part 822 are an L-shaped integrated structure. When the first mounting part 821 and the limiting part 822 rotate in the first direction, that is, when they rotate to the left, the top of the connecting rod 823 slides downward along the first sliding groove 811, and the upper end of the first mounting part 821 gradually rotates out of the hidden cavity. When the upper end of the first mounting part 821 drives the connecting piece 830 to extend out of the hidden cavity, the right outer wall of the limiting part 822 engages with the inner wall of the hidden cavity or the outer wall of the fixing part 810, or the right side of the first mounting part 821 engages with the bottom inner wall of the hidden cavity on the building, so that the first mounting part 821 and the limiting part 822 are fixed, and personnel can escape through the connecting piece 830.

[0102] It is not difficult to imagine from the lifting point device disclosed in this embodiment that the first mounting part 821 and the limiting part 822 can rotate not only up and down, but also left and right. The first sliding groove 811 can be set on the outer wall of the hidden cavity or the fixing plate 810 and is arranged laterally. The limiting part 822 extends laterally. When the first mounting part 821 rotates laterally toward the limiting part 822, the first mounting part 821 and the connecting member 830 can be housed in the hidden cavity. When the first mounting part 821 rotates in the first direction, that is, when the first mounting part 821 rotates toward the side opposite to the limiting part 822, the first mounting part 821 and the connecting member 830 extend out of the hidden cavity.

[0103] Furthermore, such as Figure 12 As shown, the fixing part 810 is provided with a toothed limiting part 814. The toothed limiting part 814 is disposed on the side wall of the first slide groove 811. The toothed limiting part 814 can be a rack. The rack is disposed on the right side of the first slide groove 811, and the left end of the rack is a tooth.

[0104] The supporting part 820 further comprises an elastic component, one end of the elastic component in the elastic direction is connected with the side of the sliding block opposite to the tooth-shaped limiting part 814, and the other end of the elastic component in the elastic direction is in abutment with the side wall of the first sliding groove 811. The elastic component can be an elastic block, a spring, an air cushion or the like, and is arranged at the left end of the sliding block.

[0105] In the natural state, under the elastic force of the elastic component, the right end of the sliding block is in contact with the tooth-shaped limiting part 814, and the two are clamped together to fix the sliding block, and further fix the connecting rod 823, the limiting part 822 and the connecting piece 830.

[0106] When the connecting rod 823 is moved, the connecting rod 823 and / or the sliding block are pushed to the left, the elastic component is compressed, the sliding block is separated from the tooth-shaped limiting part 814, and the connecting rod 823 can be freely moved, so that the first mounting part 821 drives the connecting piece 830 to rotate in the first direction. When the connecting piece 830 moves to the set position, the connecting rod 823 and / or the sliding block are released, the elastic component is restored, the sliding block is clamped with the tooth-shaped limiting part 814 on the first sliding groove 811, and further the connecting rod 823, the limiting part 822 and the connecting piece 830 are fixed.

[0107] As shown in FIG. 1, Figure 13 in some embodiments, the limiting part 822 slides with the first sliding groove 811 through the sliding block, and the connecting rod 823 is rotationally connected with the fixed part 810.

[0108] As shown in FIG. 1, Figure 14 in some embodiments, the supporting part 820 does not comprise the limiting part 822, and only comprises the first mounting part 821 and the connecting rod 823, the first mounting part 821 slides with the first sliding groove 811 through the sliding block, and the connecting rod 823 is rotationally connected with the fixed part 810.

[0109] The sliding block slides in the first sliding groove 811, drives the first mounting part 821 and the connecting rod 823 to swing, and adjusts the position of the connecting piece 830.

[0110] As shown in FIG. 1, Figure 15 in one embodiment, the fixed part 810 is provided with a rotating shaft 812 and a limiting piece 813, the rotating shaft 812 can be freely rotated, the limiting piece 813 can be a stop block, and the limiting piece 813 is located on the rotating shaft 812 or on one side of the rotating shaft 812.

[0111] The supporting part 820 comprises a rotating part 824 and a second mounting part 825, the rotating part 824 can be a sleeve ring, the sleeve ring is sleeved with the rotating shaft 812 to rotationally connect the rotating part 824 with the rotating shaft 812, the second mounting part 825 can be a rod body, one end of the second mounting part 825 is connected with the rotating part 824, and the other end of the second mounting part 825 extends away from the rotating shaft 812, and the connecting piece 830 is arranged on the second mounting part 825.

[0112] When the end of the second mounting part 825 away from the rotating shaft 812 rotates in the first direction, that is, when the end of the second mounting part 825 away from the rotating shaft 812 rotates outward from the concealed cavity, the outer end of the second mounting part 825 and the connector 830 move to the outside of the concealed cavity, and the second mounting part 825 engages with the limiting member 813, preventing the second mounting part 825 from continuing to rotate, so that the extension direction of the second mounting part 825 is perpendicular to the cavity or fixed frame 1 of the building.

[0113] Figure 15 In the illustrated embodiment, the second mounting part 825 is in a horizontally rotating state. The second mounting part 825 can also rotate vertically. The rotating part 824 and the rotating shaft 812 are arranged horizontally. The limiting member 813 is located at the lower part of the rotating shaft 812. When the second mounting part 825 rotates in the first direction, that is, when the second mounting part 825 rotates downward, the outer end of the second mounting part 825 and the connecting member 830 gradually extend out of the hidden cavity. When the second mounting part 825 reaches a horizontal state, the lower surface of the second mounting part 825 engages with the upper surface of the limiting member 813, thereby fixing the second mounting part 825 and the connecting member 830.

[0114] Furthermore, in one embodiment, the support portion 820 further includes a reinforcing member 826;

[0115] The reinforcing member 826 can be a reinforcing rod or made of metal. One end of the reinforcing member 826 is connected to the rotating part 824, and the other end of the reinforcing member 826 is connected to the second mounting part 825. The reinforcing member 826, the rotating part 824, and the second mounting part 825 are arranged in a triangle to improve the stability of the support part 820 structure.

[0116] like Figure 16 As shown, in one embodiment, the support portion 820 includes a third mounting portion 827 and a moving portion 828;

[0117] Both the third mounting part 827 and the moving part 828 can be rods. Figure 11 In the middle, the left end of the third mounting part 827 is rotatably connected to the fixing plate 810. The third mounting part 827 is provided with a first guide part 829 on the side away from the fixing plate 810, that is, the first guide part 829 is provided on the right side of the third mounting part 827. The first guide part 829 can be a slide groove or a slide rail. The connecting piece 830 is provided on the right side of the third mounting part 827.

[0118] The upper end of the moving part 828 is rotatably connected to the fixed plate 810, and the bottom end of the moving part 828 is slidably connected to the first guide part 829 through a slider;

[0119] When the third mounting portion 827 slides upward, the bottom end of the moving portion 828 slides rightward along the first guide portion 829, and the third mounting portion 827 and the connecting piece 830 are gradually accommodated into the hidden cavity; conversely, when the third mounting portion 827 rotates in the first direction, the upper end of the third mounting portion 827 and the connecting piece 830 rotate rightward, move outward of the hidden cavity, and the upper end of the moving portion 828 slides downward along the first guide portion 829; when the third mounting portion 827 reaches the horizontal state, the connecting piece 830 is located outside the hidden cavity, and the slider at the bottom end of the moving portion 828 is clamped with the left end of the first guide portion 829, so as to fix the third mounting portion 827.

[0120] It is easily conceived that the third mounting portion 827 and the moving portion 828 can also rotate transversely, and the specific setting mode is not described herein.

[0121] Further, in an embodiment, the hanging point device further comprises a locking assembly and an elastic assembly;

[0122] The elastic assembly is arranged in the hidden cavity, and the locking assembly is connected with the elastic assembly;

[0123] When the connecting piece 830 moves to the outside of the hidden cavity, the elastic assembly drives the locking assembly to move, the locking assembly is clamped with the third mounting portion 827, so as to fix the third mounting portion 827, and ensure the safety of the personnel when escaping.

[0124] Specifically, in an embodiment, the locking assembly comprises a plug rod, and a telescopic rod is fixedly arranged in the hidden cavity;

[0125] The elastic assembly comprises a telescopic rod, the telescopic rod is composed of a sleeve and a spring, the plug rod has a first end and a second end at opposite ends, and the first end of the plug rod is connected with the telescopic end of the telescopic rod;

[0126] The third mounting portion 827 is provided with a plug hole, when the connecting piece 830 moves to the outside of the hidden cavity, i.e. the third mounting portion 827 reaches the horizontal state, the telescopic rod is elongated, the second end of the plug rod is inserted into the plug hole of the third mounting portion 827, so as to fix the third mounting portion 827.

[0127] The application also provides an escape platform, comprising: a bearing platform 4 and a fixed frame 1;

[0128] The fixed frame 1 is arranged in the hole of the building wall, and the bearing platform 4 is movably connected with the fixed frame 1;

[0129] When the bearing platform 4 is in the closed state, the bearing platform 4 is clamped in the fixed frame 1 to block the hole;
