[0003] When dangerous situations occur in high-rise buildings, people inside the building are often unable to escape quickly, especially in scenarios such as fires. The elevators inside the building cannot be used or are not suitable for use, and the speed and capacity of safety passages (stairs) are low, which greatly delays the escape of people and easily creates serious safety hazards.

[0004] An escape platform is usually installed on a hole set up in a building for people to escape in an emergency, so that people in the room can evacuate quickly. When not in use, the escape platform is usually hidden in the wall in a folded manner and locked with the frame installed on the hole of the building. When encountering an emergency, a manual unlocking device is required to realize the deployment of the escape platform. However, the existing unlocking device cannot achieve the effect of stable and fast unlocking, which leads to a large safety hazard of the entire escape platform. Summary of the invention

DETAILED DESCRIPTION

[0071] An escape platform is a structure that can be opened on each floor of a building to form an escape platform on the exterior wall when a dangerous situation occurs. Existing buildings are usually equipped with casement, sliding, top-hung and bottom-hung windows for lighting and ventilation, but because the windows have small opening panels and small opening areas, they cannot form a platform for people to gather after opening, which greatly reduces the chances of trapped people escaping.

[0072] The escape platform involved in the present application can be 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 opened, a platform can be formed on the facade of the building with a certain carrying capacity. Escaping personnel can gather on the platform to wait for rescue, or use a slow-descent device to descend to a safe position to escape danger.

[0073] like Figures 1 to 7The escape platform provided in the embodiment of the present application is installed in the opening of the building, and the location of the escape platform needs to be ensured to meet the requirements of the building's facade effect. The escape platform includes a bearing platform 4 and a fixed frame 1, the fixed frame 1 is set on the opening opened in the building wall, the bearing platform 4 and the fixed frame 1 are movably connected, and a manual switch 2 is provided on one side of the fixed frame 1 in the room, and the manual switch 2 is provided with a protective structure 21. Under normal circumstances, the manual switch 2 is sealed inside the protective structure 21 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 21.

[0074] A first sealing body 41 is arranged in the frame around the carrying platform 4. When the carrying platform 4 is in a closed state, the first sealing body 41 is squeezed and sealed with a second sealing body 12 arranged on the inner side of the fixed frame 1. A guardrail 6 is arranged on the carrying platform 4. The guardrail 6 is located at the edge of the carrying platform 4 and is foldably hidden in the first accommodating space 111 of the two side frames 11 of the fixed frame 1, and is foldably hidden in the second accommodating space 112 of the upper frame of the fixed frame.

[0075] The diagonal member 5 is arranged between the two side edges of the supporting platform 4 and the two side frames 11 of the fixed frame 1, and the diagonal member 5 is hidden in the first accommodating space 111 of the two side frames 11 of the fixed frame 1; a first locking portion 42 is provided on the frame of the supporting platform 4, and the first locking portion 42 and the second locking portion 13 provided on the frame of the fixed frame form a locked state.

[0076] After the carrying platform 4 is opened by the manual switch 2, the carrying platform 4 is connected to the lower frame of the fixed frame 1, so that the carrying platform 4 is rotated toward the outdoor side and opened to the set position and stops. Specifically, the connection and rotation can be achieved through the hinge structure 131. When the carrying platform 4 is in the open state, people need to gather on the carrying platform 4 when escaping, and the carrying platform 4 should have a certain carrying capacity.

[0077] 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.

[0078] 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.

[0079] At this time, the load-bearing platform 4 has an escape function, but in order to ensure that the escapees on the load-bearing platform 4 do not fall, when the load-bearing platform 4 is in the open state, a safety guardrail 6 can be set on the side of the load-bearing platform 4 that is not connected to the wall. When the load-bearing platform 4 is opened, the guardrail 6 automatically rises to improve the safety of the load-bearing platform 4. A spring pneumatic telescopic device is provided between the load-bearing platform 4 and the guardrail 6. During the opening process of the load-bearing platform 4, under the pulling force or thrust of the spring pneumatic telescopic device, the guardrail 6 rises to a set height and locks. A gap is provided at the guardrail position of the load-bearing platform for escapees to use. After wearing the escape equipment, the escapees can escape safely through the gap without climbing over the guardrail to escape. The number and position of the gap can be set according to the usage. A railing is provided at the gap position. Before using the gap, the railing is manually opened to escape.

[0080] The fixed frame 1 is also provided with a connection part 8 of a backpack type slow-down device. When the escapee puts on the escape backpack, the slow-down rope of the backpack type slow-down device is connected to the connection part 8, and the lifting and lowering of the backpack type slow-down device is realized by the slow-down rope. Specifically, after the escapee puts on the backpack type slow-down device, the connection end of the slow-down rope is connected to the connection end of the connection part 8. In actual use, the backpack type slow-down device realizes slow-down under a certain gravity through the friction part. The slow-down rope is stored in a winch connected to the friction part. The whole component is installed in the backpack. The connection end of the slow-down rope extends out of the backpack and is connected to the connection part 8 provided on the fixed frame 1. The escapee can realize escape after fixing the backpack type slow-down device on the body through a 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 backpack type slow-down device can be provided with a descending stop device, and the descending stop device can be manually controlled. The descending stop device can increase the friction force by squeezing the friction part through the squeezing structure, and stop descending when the friction force is greater than the gravity; it can also increase the friction force by squeezing the slow-down rope through the squeezing structure, and stop descending when the friction force is greater than the gravity.

[0081] The escape platform is also provided with a recovery device 3, which 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 through the 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.

[0082] 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; a screw rod structure can also be used to achieve recovery, and the screw rod is rotated to make the nut connected to the screw rod 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.

[0083] The escape platform can also be provided with a slow-descending device 7, and escape can be achieved through the slow-descending device 7. When in use, the escapee needs to wear an escape safety harness, and after putting on the safety harness, connect the safety harness to the slow-descending rope 71 of the slow-descending device 7, and can slowly descend to a safe position or escape on the ground; the slow-descending device 7 is arranged on the indoor wall, and the number can be set to be multiple, and the connecting end for connecting with the safety harness worn by the escapee extends out of the outdoor side, so that the escapee can wear the safety harness and connect it to the connecting end of the slow-descending device to escape quickly.

[0084] The descending slow device 7 can also be arranged on the fixing frame 1, and the number can be set to be multiple. The connecting end 72 of the descending slow device 7 arranged on the fixing frame 1 also extends out of the outside of the room, so as to facilitate the escapee to escape quickly.

[0085] The descending control device 7 can also be arranged separately from the supporting platform 4. For example, a first connecting part and a third locking part connected to the descending control device 7 are provided on the fixing frame 1 or the supporting platform 4, and the number of the first connecting part and the third locking part are at least one. After the supporting platform 4 is opened, the escapee fixes the descending control device 7 to the first connecting part and locks it through the third locking part. After the escapee puts on the safety harness, the safety harness will be connected to the connecting end 72 of the descending control device. It should be noted that the number of the above-mentioned first connecting part and the third locking part is set to multiple. In actual use, it is not necessary to use multiple first connecting parts and third locking parts at the same time to realize the escape function. Instead, one escape or one escapee only needs to use a pair of first connecting parts and third locking parts. Setting multiple first connecting parts and third locking parts is convenient for the escapee to fix the safety harness on the one hand, and convenient for multiple escapees to escape at the same time on the other hand.

[0086] The slow-descent device 7 can also be set as a reciprocating operation 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 escapee first uses one of the second connecting parts to descend to a safe place or the ground, and then takes off the escape harness. At this time, the person to be escaped on the supporting platform 4 can use the other second connecting part to descend. When the second person to be escaped descends, the connecting end 72 used by the first escapee is recovered with the escape harness to the initial position on the supporting platform 4, and can be used again by the escapee. In this way, in the subsequent escape process of the escapee, there is no need to repeat the fixing work, and the person only needs to put on the escape harness to quickly escape from the dangerous environment.

[0087] The escape platform can also be provided with a fireproof heat-insulating curtain 9, which is arranged on the indoor side of the upper frame of the fixed frame 1, and the guide part of the fireproof heat-insulating curtain 9 is arranged on the indoor side of the side frame 11 of the fixed frame 1. After the escapee reaches the bearing platform 4, the fireproof heat-insulating curtain 9 can be manually pulled down, thereby forming a partition seal between the bearing platform 4 and the indoor side of the building. At this time, if there are still people in the room who have not escaped to the bearing platform 4, the fireproof heat-insulating curtain 9 can also be opened from the indoor side. After reaching the bearing platform 4, the fireproof heat-insulating curtain 9 can be closed again to form a partition layer, so that the space of the bearing platform 4 is safer to gain more escape time.

[0088] The fireproof heat-insulating curtain 9 is rotated and retracted under the axis of the accommodating space by spring force. When the downward pulling force is greater than the spring force, the heat-insulating curtain moves downward along the guide parts on both sides to the set position. A locking structure is provided at the set position. This locking structure can be opened from both indoor and outdoor sides, so that people who have not escaped to the escape platform can continue to hide and escape.

[0089] It should be noted that the descent control device 7 provided in the embodiment of the present application can also be used alone and is not limited to construction scenes, but can also be used in other scenes with height differences, such as tower cranes, mountains, bridges, mines or ships.

[0090] Based on the escape platform described above, the specific structure of the manual switch 2 is described in detail below:

[0091] See also Figure 8 The present application provides a manual unlocking switch device for an escape platform, namely the manual switch mentioned above, which specifically includes:

[0092] 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, or it can be set on the side of the building facade (close to the fixed frame) facing the room; when the trapped people in the room are affected by the fire, they can manually operate the operating part 210 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 joystick, and the shape and layout 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.

[0093] An execution unit 220 connected to the operation unit 210, wherein the execution unit 220 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 may be located inside, on or outside the fixed frame 1; the operation unit 210 is configured to move along a first direction to drive the other end of the execution unit 220 to move along the first direction;

[0094] 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 rotationally connected to the fixed frame 1, that is, the first direction is rotation upward, downward, or in any other direction.

[0095] 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.

[0096] Depend on Figure 8 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 it can also be connected to a fixed structure fixed to the carrying platform 4 (for example Figure 8 What is shown is an embodiment in which a similar hook structure is provided on the supporting 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 realize the unlocking of the supporting platform 4 and the fixed frame 1.

[0097] 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.

[0098] 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.

[0099] It can be seen from the above technical solution that the manual unlocking switch device for an escape platform provided by the present application drives the execution part 220 to move in a first direction by manually operating the operation part 210 disposed on the fixed frame, and then drives the controlled end of the unlocking part 230 through the movement of the execution part 220, so that the unlocking part 230 can unlock the pushing part 240 and the carrying platform, thereby achieving the purpose of switching the carrying platform and the fixed frame from a fixed state to an active state. The device of the present application has a simple structure and has high stability and convenience.

[0100] It should be noted that, in the present application, the operating part 210, the executing part 220, the unlocking part 230 and the pushing part 240 are only used to describe the structure for realizing the corresponding functions, and it does not mean that the device of the present application must be composed of at least the above four parts. In practical applications, it is allowed that one part is used as at least two of the above parts to constitute the device of the present application. For example, there may be a part A that realizes the function of the unlocking part 230 and the function of the pushing part 240 at the same time, that is, the structures of the two are realized by one part; for another example, there may be a part B that includes the structure of the operating part 210 and the structure of the executing part 220, that is, the structures of the two are realized by one part. Other situations are similar and will not be elaborated here.

[0101] Further, in some embodiments, Figure 8 As shown, the execution part 220 is slidably connected to the fixing frame 1, and the first direction is the direction in which the operation part 210 approaches or moves away from the fixing frame 1. At this time, the operator only needs to face the direction of the operation part 210, hold the operation part 210 and push it forward or pull it backward to realize the unlocking operation of the carrying platform 4.

[0102] When the execution part 220 and the fixing frame 1 are arranged to be in sliding connection, see Figure 8 , the structural relationship between the execution part 220 and the unlocking part 230 can be set as follows: the end of the execution part 220 away from the operating part 210 is provided with a first inclined surface 221, and the controlled end of the unlocking part 230 is provided with a wedge block that slides against the first inclined surface 221; when the execution part 220 moves along the first direction (i.e., leftward in the figure), it drives the controlled end of the unlocking part 230 to move along the third direction (upward in the figure), and the third direction may be perpendicular to the first direction or not perpendicular, for example, the third direction forms a certain angle with the first direction. At this time, the force applied by the operator in the first direction is converted into a driving force for driving the unlocking part 230 to achieve unlocking.

[0103] It should be noted that the arrangement position of the first inclined surface 221 is not limited to one method. Fig. 9 The first inclined surface 221 may also be disposed on the other side of the controlled end of the unlocking portion 230 , that is, at this time, the operator may unlock the door by pulling the operating portion 210 backward.

[0104] Furthermore, inclined surfaces may be provided on both sides of the controlled end of the unlocking portion 230, see Fig.10, that is, a second inclined plane is further provided at the end of the execution part away from the operating part, and the second inclined plane is arranged opposite to the first inclined plane, and the inclined direction is opposite. At this time, the operator can realize the unlocking operation whether pushing the operating part 210 forward or pulling the operating part 210 backward, which is more convenient for the operator to quickly complete the unlocking process of the device. At the same time, the V-shaped structure formed between the two inclined planes can realize the reverse limit of the controlled end of the unlocking part 230, preventing the unlocking part 230 from pulling the pushing part 240 in the opposite direction of the second direction, thereby destroying the stability of the carrying platform 4.

[0105] To ensure the stability of the above unlocking process, see Figure 8 The fixing frame 1 may be provided with a structure for improving stability, for example, a fixing sleeve 101 is provided; the execution part 220 passes through the fixing sleeve 101, and the execution part 220 is provided with a guide part 223 along a first direction, and the guide part 223 may be a groove structure recessed inwardly, or a convex block structure protruding outwardly, and the fixing sleeve 101 is provided with a positioning part 224 inwardly, and the positioning part 224 cooperates with the guide part 223, when the guide part 223 is a groove, the positioning part 224 is a structure extending into the groove, and when the guide part 223 is a convex block, the positioning part 224 is a groove structure, and the positioning part 224 can slide along the extension direction of the guide part 223. In this embodiment, in order to ensure that the direction of movement of the actuator 220 is a straight line, a slider-slideway structure of the guide portion 223 and the positioning portion 224 is adopted, so that the actuator 220 can move along the direction of the guide portion 223 during the movement of the actuator 220, which can reduce the resistance when the operator pushes or pulls the operating portion 210, and improve the convenience of use. It should be noted that the fixing sleeve 101 is not a necessary structure. For example, the interior of the fixing frame 1 can also be set to a structure similar to the fixing sleeve 101, that is, the fixing sleeve 101 and the fixing frame 1 are regarded as an integrated structure; or the actuator 220 can be directly passed through the fixing frame 1, and the positioning portion 224 can be regarded as a component set (or integrally formed) on the fixing frame 1.

[0106] It should be noted that when the end of the execution part 220 (the end away from the operation part 210) is specifically set, the number and position of the inclined surfaces are different, and the position of the corresponding guide part 223 is also different. For example, Figure 8 The first inclined surface 221 is shown as being located on the right side. At this time, the operator needs to push the operating portion 210 to the left side of the figure. At this time, it is required to push the front positioning portion 224 to be located at the left end of the guide portion 223. The right end of the guide portion 223 is at a certain distance from the fixing sleeve 101. Similarly, see Fig. 9, the first inclined surface 221 is shown to be located on the left side. At this time, the operator needs to pull the operating portion 210 to the right side of the figure. At this time, it is required to pull the front positioning portion 224 to be located at the right end of the guide portion 223. The left end of the guide portion 223 is at a certain distance from the fixing sleeve 101. Fig.10 , as shown, there are both the first inclined surface 221 and the second inclined surface 222. At this time, the operator can push the operating part 210 to the left side of the figure, or pull the operating part 210 to the right side of the figure. Before pushing or pulling, the positioning part 224 needs to be in the middle position of the guide part 223, and both the left and right sides of the guide part 223 are at a certain distance from the fixing sleeve 101.

[0107] Furthermore, in some embodiments, Figure 8 As shown, the device also includes a self-locking structure located on the side of the fixed frame 1 facing the interior of the room, and the self-locking structure is configured to lock the locking component 225 of the self-locking structure with the executing part 220 when the executing part 220 moves along the first direction, and when the lock between the locking component 225 and the executing part 220 is released, the executing part 220 can continue to move in the first direction or in the opposite direction of the first direction. In this embodiment, after the operator holds the operating unit 210 to unlock the carrying platform 4, if the device of the present application automatically returns to the locked state due to the rebound of the spring or the misoperation of other personnel before the carrying platform 4 starts to unfold, the operator will have to re-execute the unlocking process. In order to solve the problem of "reverse drive", a self-locking structure is set up, and the execution unit 220 can be locked by using the locking component 225 after the operator completes the unlocking operation, so that it cannot be moved temporarily, thereby ensuring that the device is always in the unlocked state. At this time, the escapee can wait for the carrying platform 4 to be fully unfolded to reach the platform; when the platform is no longer needed, the self-locking structure can be released to restore the device of the present application to the state before unlocking.

[0108] The above embodiments describe multiple embodiments in which the execution unit 220 is slidably connected to the fixed frame 1. Another implementation method is described below. Fig.11 In the embodiment shown, in the device of the present application:

[0109] The execution part 220 is rotationally connected to the first fulcrum 102 on the fixed frame 1, and the first direction is clockwise or counterclockwise along the first fulcrum 102; at this time, when the operator holds the operating part 210, he can "bend" the operating part 210 upward, downward or in any direction as shown in the figure, thereby realizing the motion control of the execution part 220.

[0110] It should be noted that, in this embodiment, the first fulcrum 102 can be considered as a rotation point, or a rotation axis perpendicular to the paper surface, which is not limited here.

[0111] by Fig.11 In the example shown, when the operator holds the handle 210 and rotates it downward (clockwise along the first fulcrum), the corresponding actuator 220 will rotate clockwise, and the other end will drive the corresponding rod to move upward. In order to make the movement in a stable direction, a corresponding structure can be set, for example:

[0112] A first guide portion 226 is provided at one end of the execution portion 220 away from the operating portion 210, and the first guide portion 226 may be a long strip-shaped slot structure; a guide slider 231 is provided at the controlled end of the unlocking portion 230, and the guide slider 231 is slidably connected to the first guide portion 226 along the extension direction of the first guide portion 226.

[0113] See also Fig.11 and Fig.12 Before the unlocking process, the guide slider 231 is located at the right end of the first guide portion 226. When the operator holds the handle 210 and rotates it downward, the end of the actuator 220 will move in the clockwise direction, while driving the guide slider 231 to move in the direction of the first guide portion 226 until the guide slider 231 moves to the left end of the first guide portion 226, and the actuator 220 can no longer rotate.

[0114] It should be noted that in other embodiments, the setting positions of the first guide portion 226 and the guide slider 231 can be interchanged, that is, the guide slider 231 is provided at the end of the execution portion 220 away from the operating portion 210, and the first guide portion 226 is provided at the controlled end of the unlocking portion 230, which is not limited here.

[0115] The above describes an embodiment in which the execution part 220 is rotatably connected to the fixing frame 1 along the first fulcrum 102. In addition, in some other embodiments, there may be another connection method, that is, see Fig.13 , in the device of the present application:

[0116] The executing part 220 is rotatably connected to the fixed frame 1; at this time, the executing part 220 can be set in a direction perpendicular to the outer surface of the fixed frame 1, and the first direction is a clockwise or counterclockwise direction along the axis of the executing part 220; at this time, the executing part 220 can be a cylindrical structure, and the rotation axis is the central axis. Different from the aforementioned embodiment, the rotation axis and the first fulcrum are in a vertical relationship.

[0117] A gear 227 is provided at one end of the execution part 220 away from the operating part 210; a rack 228 is provided at the controlled end of the unlocking part 230 to cooperate with the gear 227; when the execution part 220 moves (rotates) along the first direction, it drives the controlled end of the unlocking part 230 to move along the third direction, and the third direction is the direction in which the rack 228 extends.

[0118] See also Fig.13 and Fig.14 In this embodiment, the operator holds the operating unit 210, which may be a crank, and when the operating unit 210 is shaken to cause the actuator 220 to rotate, the gear 227 rotates, thereby driving the meshing rack to move along a predetermined trajectory to achieve unlocking. Although the gear rack structure takes longer to unlock than the previous embodiment, the driving stability of this structure is the highest, and the problem of reverse driving is further avoided.

[0119] In addition to the aforementioned implementations, in some other embodiments, the execution unit 220 may be configured in various forms, for example, Fig.15 What is shown is an embodiment in which one end of the execution part 220 away from the operation part 210 is connected to the controlled end of the unlocking part 230 through a rope structure. Fig.16 What is shown is an embodiment in which one end of the execution part 220 away from the operation part 210 is connected to the controlled end of the unlocking part 230 through a chain structure.

[0120] It should be noted that the additional structures mentioned in the above embodiments are applicable to other embodiments. They are described as examples and are not all shown in the corresponding drawings. They should not be considered as limitations on the above technical features.

[0121] In the present application, the unlocking part 230 is a component used to realize locking and unlocking. When the execution part 220 and the controlled end of the unlocking part 230 have an action relationship, the driving force is transferred to the unlocking part 230. Fig.13 In this embodiment, the unlocking unit 230 specifically includes:

[0122] A connecting block 103 fixedly mounted in the fixing frame 1;

[0123] A first unlocking rod 232 is slidably provided in the connection block 103 along the third direction; one end of the first unlocking rod 232 is connected to the end of the execution part 220 away from the operation part 210, and is driven by the execution part 220 to move along the third direction; the other end of the first unlocking rod 232 is hinged to the connection rod 233;

[0124] A second unlocking rod 234; one end of the second unlocking rod 234 is hinged to the other end of the connecting rod 233, and the other end is hinged to the connecting block 103;

[0125] A third unlocking rod 235 is rotatably connected to the inner wall of the fixed frame 1, and a second guide portion 236 is provided at one end of the third unlocking rod 235, and the second guide portion 236 can be a bar-shaped groove body; a guide block 237 is provided at the hinge of the connecting rod 233 and the second unlocking rod 234, and the guide block 237 can slide along the second guide portion 236; in some other embodiments, the setting positions of the second guide portion 236 and the guide block 237 can also be interchanged, that is, a guide block 237 is provided at one end of the third unlocking rod 235, and a second guide portion 236 is provided at the hinge of the connecting rod 233 and the second unlocking rod 234.

[0126] a fourth unlocking lever 238, one end of which is hinged to one end of the third unlocking lever 235 away from the second guide portion 236, and the other end of which is hinged to the pushing portion 240;

[0127] One end of the pushing portion 240 is rotatably connected to the inner wall of the fixing frame 1 , and the other end thereof abuts against the carrying platform 4 along the opposite direction of the second direction.

[0128] In this embodiment, the driving force along the first direction is finally converted into the driving force along the second direction through the structural relationship between the multiple connecting rods, thereby realizing the unlocking between the pushing part 240 and the carrying platform 4. Fig.13 and Fig.14 To explain the specific unlocking process:

[0129] When the first unlocking rod 232 is driven by the actuator 220, due to the limitation of the connecting block 103, the first unlocking rod 232 moves in the vertical upward direction, thereby driving the connecting rod 233 to move upward, and the other end of the connecting rod 233 pushes the second unlocking rod 234 to rotate in the clockwise direction. At the same time, the guide block 237 at the hinge point of the connecting rod 233 and the second unlocking rod 234 begins to move upward along the second guide portion 236. During the upward movement of the guide block 237, due to the limitation caused by the rotation of the second unlocking rod 234, the third unlocking rod 235 will rotate in the counterclockwise direction, thereby pushing the fourth unlocking rod 238 to move to the left side of the figure, and the end of the fourth unlocking rod 238 abuts the pushing portion 240, so that the pushing portion 240 rotates counterclockwise, and the end (lower end) of the pushing portion 240 that abuts against the carrying platform 4 gradually separates from the carrying platform 4 and has a certain distance, finally achieving the unlocking effect. At this time, the carrying platform 4 can rotate relative to the fixed frame 1 to move from the side range of the fixed frame ( Fig.14 The dotted line part) is moved out to realize the expansion operation.

[0130] It should be noted that the structure of the unlocking portion 230 of this embodiment is applicable to all the aforementioned embodiments.

[0131] For further information, see Figure 8 , Fig.15 , Fig.16 In some other embodiments, the unlocking unit 230 may further include:

[0132] The resetting elastic member 239 may be a spring or other elastic material; one end of the resetting elastic member 239 is connected to the controlled end of the unlocking portion 230, and the other end is fixedly connected to the fixing block 104 fixedly connected to the inner wall of the fixing frame 1. It should be noted that the fixing block 104 refers to a structure fixed to the inner wall of the fixing frame 1 or the fixing frame 1 itself. Fig.15 or Fig.16 In the illustrated embodiment, the fixing block 104 may be referred to as the connecting block 103 .

[0133] In this embodiment, the function of the reset elastic member 239 is that when the actuator 220 no longer continues to provide the unlocking driving force, the device of the present application can automatically return to the unlocked state through the elasticity of the reset elastic member 239. In practical applications, the reset elastic member 239 and the aforementioned self-locking structure can be used in conjunction with each other, that is, the self-locking structure is used to limit the automatic reset of the reset elastic member 239, etc.

[0134] For further information, see Figure 8 In some embodiments, the apparatus further comprises:

[0135] The protective structure 21 is covered on the outside of the operating part 210 and fixed on the side of the fixed frame 1 facing the room. The protective structure 21 is provided with an active opening for the operator to operate the operating part. The form of the active opening can be a sliding door, a hinged door or any other form, which is not limited here.

[0136] Corresponding to the manual unlocking switch device of the escape platform provided in the aforementioned embodiment, the present application further provides an escape platform, comprising: a carrying platform 4 and a fixing frame 1;

[0137] The fixing frame 1 is arranged in a hole opened in a building wall, and the carrying platform 4 is movably connected to the fixing frame 1;

[0138] When the carrying platform 4 is in a closed state, the carrying platform 4 is clamped in the fixing frame 1 to block the hole;

[0139] When the carrying platform 4 is in the open state, the carrying platform 4 moves to the outside of the building wall to form a platform for escaping personnel to stay;

[0140] It also includes the escape platform manual unlocking switch device described in any of the above embodiments;

[0141] The manual unlocking switch device of the escape platform is arranged on the fixed frame or the facade of the building and faces the side of the room to control the load-bearing platform 4 to switch from the closed state to the open state. The closed state refers to the state in which the load-bearing platform 4 is completely located in the fixed frame 1 and stably locked with the fixed frame, and the open state refers to the state after the manual unlocking switch device of the escape platform completes the unlocking process.

[0142] The above specific implementation methods further illustrate the purpose, technical solutions and beneficial effects of the present application in detail. It should be understood that the above are only specific implementation methods of the present application and are not used to limit the protection scope of the present application. Any modifications, equivalent substitutions, improvements, etc. made on the basis of the technical solutions of the present application should be included in the protection scope of the present application.
