Description

Technical Field

[0001] The present invention relates to the technical field of fire-fighting equipment, and particularly relates to a fire-escape anti-theft window and a fire-escape device. Background Art

[0002] Whether modern housing can quickly escape in case of a fire plays a crucial role when a fire occurs. Currently, for buildings with anti-theft nets, how to effectively combine the anti-theft nets to design an escape passage on the building exterior wall has become an urgent problem to be solved. In this field, through the retrieval of the prior art, Patent CN201910698546.1 discloses a novel dual-purpose device of an anti-theft net and a fire ladder, the fire ladder constituted thereby, and a using method. Among them, a first switch door and a second switch door are respectively arranged on the anti-theft net, so that while the second anti-theft net main body slides down, the first switch door and the second switch door are opened simultaneously, forming an escape passage inside the anti-theft net, facilitating escape personnel to climb inside the anti-theft net, and solving the problem that escape personnel are completely exposed outside the building during the climbing process from the outside of the anti-theft net, with low safety in use.

[0003] Although this technical solution enables climbing inside the anti-theft net and can improve the safety of climbing the anti-theft net to a certain extent, however, such a design can only achieve unilateral protection between adjacent two floors and cannot achieve effective protection during the turnover process on the same floor. Specifically, as Figure 1 shown, during the process of turning from the same floor to the lower floor, the escape personnel need to move to the side close to the second anti-theft net main body 220 to enter the second switch door 241. Since the second anti-theft net main body 220 on the same floor has completely slid down to the upper end of the next floor and is connected to the first anti-theft net main body 210 of the next floor, therefore, the structural design of this anti-theft net has no protective measures when each floor of personnel turns to enter the second switch door 241, and there are also great potential safety hazards. Therefore, from the perspective of safety, this technology is also difficult to be popularized and applied during implementation. Summary of the Invention

[0004] Aiming at the problems existing in the above-mentioned prior art, the present invention provides a fire-escape anti-theft window and a fire-escape device, providing a more reliable escape passage with higher safety.

[0005] The technical solution adopted by the present invention is as follows:

[0006] A fire escape anti-theft window and a fire escape device, including an escape space on this floor and a front protection structure located outside the escape space on this floor. The front protection structure includes a first protection main body and a second protection main body. The first protection main body includes a first frame body and a plurality of first protection columns fixedly installed on the first frame body. The second protection main body includes a second frame body and a plurality of second protection columns fixedly installed on the second frame body. The second frame body is located below the first frame body. The second protection columns are slidably matched with sliding parts arranged on the first frame body. The first protection columns and the second protection columns are arranged at intervals and crosswise.

[0007] The prior art can only achieve one-sided protection between adjacent floors and cannot achieve effective protection during the turnover process on this floor. In this technical solution, since the first protection columns and the second protection columns are arranged at intervals and crosswise, and the second protection columns are slidably matched with the sliding parts arranged on the first frame body, when the second protection main body is in the downward movement state, the second protection main body can effectively protect the escape space outside the layer between two adjacent floors. At the same time, since the first protection columns can still effectively protect the escape space on this floor after the second protection main body moves downward, therefore, during the climbing process of the escape personnel inside the anti-theft window, both the escape space on this floor and the escape space outside the layer can be effectively protected, thus providing a more reliable escape passage and higher safety during the escape process.

[0008] Specifically, the sliding part is a through hole arranged on the first frame body, and the through hole is arranged at intervals and crosswise with the first protection columns. The upper end of the second protection column is provided with a reduced opening, and the first frame body is provided with a docking opening corresponding to the reduced opening. The reduced opening is located inside the docking opening when the anti-theft window is in the unopened state.

[0009] Furthermore, in order to provide a more comprehensive protection effect, a left protection structure and a right protection structure are respectively arranged on the left and right sides of the front protection structure. The space enclosed by the front protection structure, the left protection structure and the right protection structure is the escape space on this floor. A first escape exit is arranged above the escape space on this floor, and a second escape exit is arranged below the escape space on this floor. The first escape exit and the second escape exit are arranged in a staggered manner.

[0010] Specifically, the left protection structure and the right protection structure can be fixed structures or structures the same as the front protection structure, which can realize the downward movement of the second protection main body relative to the first protection main body and provide a more comprehensive protection effect for the escape space on this floor and the escape space outside the layer.

[0011] When the left protection structure and the right protection structure are both the same as the front protection structure, the first frame bodies and the second frame bodies of the three are respectively connected end to end to form a U-shaped structure.

[0012] Furthermore, in order to facilitate the connection between the upper and lower floors in dangerous moments, a first escape door for opening a first escape exit is provided at the top of the anti-theft window, and a second escape door for opening a second escape exit is provided at the bottom of the anti-theft window.

[0013] It should be noted that children may play near the windows. Therefore, a protective net can be used instead of the second escape door at the second escape exit to avoid safety accidents. There are buckles on three sides of the protective net. If a fire occurs, the buckles can be reset by prying them open with a screwdriver, and the second escape exit can be opened by opening the protective net.

[0014] Furthermore, in order to quickly connect the escape passages between floors, it also includes a locking mechanism for controlling the second protection body to slide downward relative to the first protection body and simultaneously controlling the opening of the first escape door and the second escape door.

[0015] Furthermore, in order to quickly achieve the connection of escape passages between floors, the locking mechanism includes a first locking mechanism and a second locking mechanism, the first locking mechanism includes a first limiting member arranged on the second protective column and a second limiting member arranged on the first escape door, the first limiting member at least giving the second limiting member an upward supporting force; the second locking mechanism includes a triggering mechanism, a lap mechanism and a limiting structure, the triggering mechanism includes a trigger rod arranged on the first protective body and a contact arranged at the lower end of the trigger rod, the lap mechanism includes a spring lock tongue mechanism arranged on the second escape door, the lock tongue of the spring lock tongue mechanism is lapped on the first frame in an extended state, the trigger rod drives the contact to move downward, and the contact pushes the lock tongue backward so that the lock tongue is separated from the first frame, and the limiting structure includes a third limiting member arranged on the second escape door and a fourth limiting member arranged on the second frame, the third limiting member at least giving the fourth limiting member an upward supporting force.

[0016] It should be noted that the trigger rod is slidably matched with the first protective body, and the upper end of the trigger rod protrudes from the upper end of the first frame. In order to realize the hidden setting of the trigger rod, the trigger rod is set in any first protective column, and the trigger rod is slidably matched with the first protective column. The first protective column is protective column A, and the lower end of the protective column A has an avoidance space, and the height of the avoidance space is greater than or equal to the height of the trigger rod protruding from the first frame.

[0017] In addition, the upper end of the trigger rod can also be flush with the upper end of the first frame to avoid accidental touch. At the same time, the lower end of the second frame of the upper anti-theft window is provided with a contact head corresponding to the position of the trigger rod. The contact head protrudes from the lower end surface of the second frame. The contact head can penetrate deep into the first protective column where the trigger rod is installed. During the descent of the second frame, the trigger head can drive the trigger rod, so that the entire escape device forms a mechanical linkage effect.

[0018] It should be noted that the contact has a wedge-shaped surface on one side facing the lock tongue. When the trigger rod moves downward, the wedge-shaped surface squeezes the lock tongue to achieve the separation of the lock tongue from the first frame.

[0019] The locking mechanism in the technical solution has the following working principle: the trigger rod plays a role in the linkage control between adjacent floors, that is, after the second protective body of the floor where the fire occurs falls, the second frame body will achieve the resistance to the trigger rod of the anti-theft window on the lower floor, and the trigger rod of the anti-theft window on the lower floor will move down, and the wedge-shaped surface on the contact will realize the push of the lock tongue, and the lock tongue will be separated from the first frame body, and the third limiter on the second escape door will at least give an upward support force to the fourth limiter on the second frame body. Since the second escape door is separated from the lock tongue, the second escape door flips down and opens, and the support force disappears, then the second protective body moves down under the action of gravity, and at the same time, during the downward movement of the second protective body, the support force of the first limiter set on the first protective column to the second limiter on the first escape door also disappears at the same time, so the first escape door also flips down and opens. By analogy, it is realized that when a fire occurs on this floor, the operation on this floor can realize the automatic opening of the escape passages of all floors below this floor.

[0020] It should be noted that in order to facilitate manual or remote opening of the escape passage, a manual switch and an electronic remote control switch are also included. The manual switch includes an operating part that facilitates manual operation of the lock tongue retraction, that is, both the manual switch and the remote control switch can be used when a fire occurs on this floor; the electronic remote control switch includes a motor, a controller and a remote control for electrically driving the lock tongue to retract. The remote control transmits a control signal to the controller, and the controller controls the start of the motor to drive the lock tongue. Of course, the control method for the motor can also be other remote control methods, such as mobile terminals such as mobile phones, not limited to remote controls.

[0021] It should be noted that the remote control can realize wall-penetrating remote control, so that the escape passage can be opened in any space in the room. In addition, the technical solution can also be combined with the alarm system and / or night lighting, so that the alarm system and the night lighting are turned on at the same time when the escape passage is opened.

[0022] It should be noted that the device can also be equipped with a smoke alarm. When the elderly are unable to move, they can use the remote control to open the escape route and call for help outside the building. At the same time, the smoke alarm can also serve as an early alarm prompt, making it convenient to open the escape route with the remote control.

[0023] The output shaft of the motor is in transmission connection with the lock tongue, and is used to electrically control the retraction of the lock tongue. The retraction of the lock tongue can be achieved by a gear rack transmission between the output shaft of the motor and the lock tongue, and of course other transmission structures can also be used.

[0024] The present technical solution also provides a fire escape device, including a plurality of fire escape and anti-theft windows arranged in sequence in the vertical direction.

[0025] Further, in order to make the protection measures between adjacent floors more reliable, a locking mechanism is provided between the upper end of the second frame body and the first frame body of a fire escape and anti-theft window on the lower floor.

[0026] That is to say, when the second frame body drops onto the first frame body of the next floor, the locking mechanism is locked, making the connection between the second protection main body of the upper anti-theft window and the first protection main body of the lower anti-theft window more reliable, and further improving the protection effect on the out-of-layer protection space.

[0027] Specifically, the locking mechanism includes a card slot provided at the upper end of the first frame body and a clamping member provided at the lower end of the second frame body. When the second frame body drops onto the first frame body of the lower layer, the clamping member is clamped in the card slot.

[0028] Further, in order to further reduce the fear during the escape climbing process, it also includes a first escape ladder and a second escape ladder. The area between adjacent fire escape and anti-theft windows is the out-of-layer escape space. The first escape ladder is arranged in the escape space of this layer, and the second escape ladder is arranged in the out-of-layer escape space.

[0029] The existing escape method requires climbing from the inside of the anti-theft net during the escape process. When people climb and see downstairs, they will have greater fear during the escape process.

[0030] In the present technical solution, specifically, the best way for the first escape ladder and the second escape ladder is to be arranged on the side against the wall to avoid the psychological fear caused by the high floor during the escape process.

[0031] Of course, it can also be that the first escape ladder is arranged on the side close to the left protection structure, and the second escape ladder is arranged on the side against the wall.

[0032] The upper end of the first escape ladder is communicated with the first escape exit, the lower end of the first escape ladder is fixed at the bottom of the anti-theft window, the upper end of the second escape ladder is communicated with the second escape exit, and the lower end of the second escape ladder extends to the upper end of the anti-theft window on the next floor.

[0033] Further, the second escape ladder is a folding ladder. When the device is not in use, the folding ladder is in a folded state. When the device is in use, the folding ladder is in an open state to realize the connection between adjacent floors.

[0034] Further, after the people on this floor escape, in order to prevent the flames in the floor from further spreading and affecting the upper floors, it also includes a fireproof rolling curtain device arranged inside the escape space of this floor.

[0035] The fireproof rolling shutter device includes a fireproof rolling shutter, a reel, and a heat-melting wire. One end of the fireproof rolling shutter is fixed to the upper end inside the escape space of this floor, and the other end of the fireproof rolling shutter is fixed to the reel, and the fireproof rolling shutter is wound around the reel. The heat-melting wire bundles and fixes the reel with the wound fireproof rolling shutter to the upper end inside the escape space of this floor.

[0036] During a fire, the heat-melting wire is melted by heat. Of course, the melting method of the heat-melting wire can be electric heating melting. Then, the fireproof rolling shutter moves downwards and unfolds under the action of gravity, preventing the further spread of flames and thick smoke.

[0037] The beneficial effects of the present invention are as follows: The prior art can only achieve unilateral protection between adjacent floors and cannot achieve effective protection during the turnover process of this floor. In this technical solution, since the first protection columns and the second protection columns are arranged at intervals and crosswise, and the second protection columns are slidably matched with the sliding parts arranged on the first frame body, when the second protection main body is in the downward movement state, the second protection main body can effectively protect the out-of-floor escape space between two adjacent floors. At the same time, since the first protection columns can still effectively protect the escape space of this floor after the second protection main body moves downwards, during the climbing process of the escape personnel inside the anti-theft window, whether it is the escape space of this floor or the out-of-floor escape space, effective protection can be obtained, thereby providing a more reliable escape passage and higher safety during the escape process.

DETAILED DESCRIPTION

[0055] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0056] Accordingly, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0057] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments may be combined with each other.

[0058] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0059] Embodiment 1:

[0060] As Figures 2 - 16 shown, this embodiment provides a fire escape anti-theft window and a fire escape device, including an escape space 1 on this floor and a front protection structure 2 located outside the escape space 1 on this floor. The front protection structure 2 includes a first protection main body and a second protection main body. The first protection main body includes a first frame body 3 and a plurality of first protection columns 4 fixedly installed on the first frame body 3. The second protection main body includes a second frame body 5 and a plurality of second protection columns 6 fixedly installed on the second frame body 5. The second frame body 5 is located below the first frame body 3. The second protection columns 6 are slidably matched with the sliding parts arranged on the first frame body 3. The first protection columns 4 and the second protection columns 6 are arranged at intervals and crosswise.

[0061] The prior art can only achieve one-sided protection between adjacent floors and cannot achieve effective protection during the turnover process on this floor. In this technical solution, since the first protection columns 4 and the second protection columns 6 are arranged at intervals and crosswise, and the second protection columns 6 are slidably matched with the sliding parts arranged on the first frame body 3, when the second protection main body is in the downward movement state, the second protection main body can effectively protect the out-of-floor escape space 7 between adjacent two floors. At the same time, since the first protection columns 4 can still effectively protect the escape space 1 on this floor after the second protection main body moves downward, therefore, during the climbing process of the escape personnel inside the anti-theft window, both the escape space 1 on this floor and the out-of-floor escape space 7 can be effectively protected, thus providing a more reliable escape passage and higher safety during the escape process.

[0062] Specifically, the sliding part is a through hole arranged on the first frame body 3, and the through hole is arranged at intervals and crosswise with the first protection columns 4. The upper end of the second protection column 6 is provided with a reduced opening, and the first frame body 3 is provided with a docking port corresponding to the reduced opening. The reduced opening is located inside the docking port when the anti-theft window 25 is in the unopened state.

[0063] It should be noted that the first protective column 4 and the second protective column 6 are arranged at intervals and cross each other. There is no limit to the number of intervals between the two. For example, there may be one first protective column 4 between two second protective columns 6, or there may be two or other numbers of first protective columns 4; or, there may be one second protective column 6 between two first protective columns 4, or there may be two or other numbers of second protective columns 6. During implementation, the number of intervals of the protective columns can be determined according to the specific distance between the two protective columns, which are all easily conceivable designs and fall within the protection scope of the present technology.

[0064] Embodiment 2:

[0065] This embodiment is optimized based on the above Embodiment 1.

[0066] In order to provide a more comprehensive protection effect, it further includes a left protective structure 8 and a right protective structure 9 respectively arranged on the left and right sides of the front protective structure 2. The space enclosed by the front protective structure 2, the left protective structure 8 and the right protective structure 9 is the escape space 1 on this floor. There is a first escape exit above the escape space 1 on this floor, and a second escape exit is provided below the escape space 1 on this floor. The first escape exit and the second escape exit are arranged in a staggered manner.

[0067] Specifically, the left protective structure 8 and the right protective structure 9 can be fixed structures, or the same structures as the front protective structure 2, which can realize the downward movement of the second protective body relative to the first protective body, and at the same time provide a more comprehensive protection effect for the escape space 1 on this floor and the escape space 7 outside the floor.

[0068] When the left protective structure 8 and the right protective structure 9 are both the same as the front protective structure 2, the first frameworks 3 and the second frameworks 5 of the three are respectively connected end to end to form a U-shaped structure.

[0069] Embodiment 3:

[0070] This embodiment is optimized based on the above Embodiment 2.

[0071] In order to facilitate the connection between floors in case of danger, a first escape door 10 for opening the first escape exit is provided at the top of the anti-theft window 25, and a second escape door 11 for opening the second escape exit is provided at the bottom of the anti-theft window 25.

[0072] It should be noted that children may play by the window. Therefore, the position of the second escape exit can be replaced by a protective net instead of the second escape door to avoid safety accidents. There are buckles on three sides of the protective net. After a fire breaks out, the buckles can be pried open with a screwdriver, and the buckles can be reset, and the protective net can be opened to open the second escape exit.

[0073] Embodiment 4:

[0074] This embodiment is optimized based on the above-mentioned Embodiment 3.

[0075] In order to quickly connect the escape passages between floors, it further includes a locking mechanism for controlling the second protection main body to slide relative to the first protection main body while controlling the opening of the first escape door 10 and the second escape door 11.

[0076] Embodiment 5:

[0077] This embodiment is optimized based on the above-mentioned Embodiment 4.

[0078] In order to quickly connect the escape passages between floors, the locking mechanism includes a first locking mechanism and a second locking mechanism. The first locking mechanism includes a first limiting member 12 provided on the second protection column 6 and a second limiting member 13 provided on the first escape door 10. The first limiting member 12 provides at least an upward supporting force to the second limiting member 13. The second locking mechanism includes a triggering mechanism, a latching mechanism and a limiting structure. The triggering mechanism includes a triggering rod 16 provided on the first protection main body and a contact head 17 provided at the lower end of the triggering rod 16. The latching mechanism includes a spring lock tongue mechanism provided on the second escape door 11. When the lock tongue 19 of the spring lock tongue mechanism extends, it latches on the first frame body 3. The triggering rod 16 drives the contact head 17 to move downward, and the contact head 17 pushes the lock tongue 19 backward so that the lock tongue 19 is separated from the first frame body 3. The limiting structure includes a third limiting member 14 provided on the second escape door 11 and a fourth limiting member provided on the second frame body 5. The third limiting member 14 provides at least an upward supporting force to the fourth limiting member.

[0079] It should be noted that in order to ensure the stability of the connection between the first protection main body and the second protection main body, two second locking mechanisms can be symmetrically arranged between them.

[0080] It should be noted that the triggering rod 16 is slidably matched with the first frame body 3, and the upper end of the triggering rod 16 protrudes from the upper end of the first frame body 3. In order to achieve the hidden setting of the triggering rod 16, the triggering rod 16 is arranged in any one of the first protection columns 4. The triggering rod 16 is slidably matched with the first protection column 4. This first protection column 4 is protection column A. The lower end of protection column A has an avoidance space, and the height of the avoidance space is greater than or equal to the height of the triggering rod 16 protruding from the first frame body 3.

[0081] Such as Figure 16As shown in the figure, in addition, the upper end of the trigger rod 16 can also be flush with the upper end of the first frame body 3 to avoid accidental touch. At the same time, a contact head 35 corresponding to the position of the trigger rod 16 is provided at the lower end of the second frame body 5 of the upper anti-theft window 25. The contact head 35 protrudes from the lower end face of the second frame body 5, and the contact head 35 can penetrate into the first protection column 4 where the trigger rod 16 is installed. During the descent of the second frame body 5, the contact head 35 can drive the trigger rod 16, so that the entire escape device forms a mechanical linkage effect.

[0082] It should be noted that one side of the contact head 17 facing the lock tongue 19 has a wedge-shaped surface 18. During the downward movement of the trigger rod 16, the wedge-shaped surface 18 squeezes the lock tongue 19 to realize the separation of the lock tongue 19 from the first frame body 3.

[0083] Adopting the locking mechanism in this technical solution, its working principle is as follows: The trigger rod 16 plays a role in the linkage control between adjacent floors. That is, after the second protection main body on the floor where a fire occurs drops, the second frame body 5 will contact the trigger rod 16 of the lower anti-theft window. The trigger rod 16 of the lower anti-theft window moves downward, and the wedge-shaped surface 18 on the contact head 17 is used to push the lock tongue 19. The lock tongue 19 separates from the first frame body 3. The third limiting member 14 on the second escape door 11 gives at least an upward supporting force to the fourth limiting member on the second frame body 5. Since the second escape door 11 is separated from the lock tongue 19, the second escape door 11 flips downward to open, and when this supporting force disappears, the second protection main body moves downward under the action of gravity. At the same time, during the downward movement of the second protection main body, the supporting force of the first limiting member 12 provided on the first protection column 4 to the second limiting member 13 on the first escape door 10 also disappears. Therefore, the first escape door 10 also flips downward to open. And so on, when a fire occurs on this floor, the automatic opening of the escape channels on all floors below this floor can be realized by operating on this floor.

[0084] It should be noted that in order to facilitate the manual opening or remote control opening of the escape channel, a manual switch and an electronic remote control switch are also included. The manual switch includes an operation part 20 that facilitates the manual retraction of the lock tongue 19. That is, when a fire occurs on this floor, both the manual switch and the remote control switch can be used; The electronic remote control switch includes a motor 21 for electrically driving the retraction of the lock tongue 19, a controller, and a remote control. The remote control transmits a control signal to the controller, and the controller controls the start of the motor 21 to realize the driving of the lock tongue 19. Of course, the control method for the motor 21 can also be other remote control methods, such as mobile terminals like mobile phones, not limited to remote controls.

[0085] It should be noted that the remote control can achieve wall-penetrating remote control so that the escape passage can be opened in any space indoors. In addition, this technical solution can also be combined with an alarm system and / or a night light, and the alarm system and the night light are both turned on simultaneously when the escape passage is opened.

[0086] It should be noted that a smoke alarm can also be set in this device. When the elderly are inconvenient to move, they can use the remote control to open the escape passage to call for help outside the building. At the same time, the smoke alarm can also play a role in early warning and prompt, facilitating the opening of the escape passage with the remote control.

[0087] The output shaft of the motor 21 is in transmission connection with the lock tongue 19 for electrically controlling the retraction of the lock tongue 19. The output shaft of the motor 21 and the lock tongue 19 can adopt a gear-rack transmission method to realize the retraction of the lock tongue 19. Of course, it can also be other transmission structures.

[0088] It should be noted that the first limiting member 12 is a crossbar provided on the second protective column 6. A first opening 23 is provided on the side of the crossbar facing the first escape door 10. The second limiting member 13 is a hanging column provided on the first escape door 10. When the device is not in use, the end of the hanging column is located in the opening 23. When the crossbar moves down with the second protective column 6, the supporting force of the first opening 23 on the hanging column disappears, and the first escape door 10 flips, so that the hanging column disengages from the first opening 23.

[0089] It should be noted that any number of first openings 23 can be provided on the crossbar, and any number of hanging columns corresponding to the first openings 23 can be provided on the first escape door 10.

[0090] The third limiting member 14 is a hanging column provided on the second escape door 11, and the fourth limiting member is a second opening 24 provided on the second frame body 5. When the device is not in use, the end of the hanging column is located in the second opening 24. When the lock tongue 19 retracts, under the action of gravity, the second escape door 11 flips, and the supporting force of the hanging column on the second protective main body through the second opening 24 disappears, and the second protective main body moves down under the action of gravity.

[0091] The hanging columns on the second escape door 11 and the second openings 24 on the second frame body 5 can also be set to any number.

[0092] Embodiment 6:

[0093] This technical solution also provides a fire escape device, including a plurality of fire escape and anti-theft windows 25 arranged in sequence in the vertical direction as described in any one of Embodiments 1-5.

[0094] Embodiment 7:

[0095] This embodiment is optimized on the basis of the above Embodiment 6.

[0096] In order to make the protective measures between adjacent floors more reliable, a locking mechanism is provided between the upper end of the second frame body 5 and the upper end of the first frame body 3 of a kind of fire escape and anti-theft window 25 on the lower floor.

[0097] That is to say, when the second frame body 5 descends onto the first frame body 3 on the next lower floor, the locking mechanism is locked, making the connection between the second protection main body of the upper-layer anti-theft window and the first protection main body of the lower-layer anti-theft window more reliable, and further improving the protection effect on the out-of-layer protection space.

[0098] Specifically, the locking mechanism includes a card slot 26 provided at the upper end of the first frame body 3 and a clamping member 27 provided at the lower end of the second frame body 5. When the second frame body 5 descends onto the first frame body 3 on the lower layer, the clamping member 27 is clamped in the card slot 26.

[0099] Embodiment 8:

[0100] This embodiment is optimized on the basis of the above Embodiment 7.

[0101] In order to further reduce the fear during the escape climbing process and provide a more relaxed climbing method, it further includes a first escape ladder 28 and a second escape ladder 29. The area between adjacent fire escape and anti-theft windows 25 is the out-of-layer escape space 7. The first escape ladder 28 is arranged in the in-layer escape space 1 of this layer, and the second escape ladder 29 is arranged in the out-of-layer escape space 7.

[0102] The existing escape method requires climbing from the inside of the anti-theft net during the escape process, that is, facing the outside wall during the climbing process. Then, when a person sees downstairs during the climbing process, it will cause greater fear during the escape process.

[0103] In this technical solution, specifically, the best way for the first escape ladder 28 and the second escape ladder 29 is to be arranged on the side close to the wall to avoid the psychological fear caused by the high floor during the escape process.

[0104] Of course, it can also be that the first escape ladder 28 is arranged on the side close to the left protective structure 8, and the second escape ladder 29 is arranged on the side close to the wall.

[0105] The upper end of the first escape ladder 28 is communicated with the first escape exit, the lower end of the first escape ladder 28 is fixed at the bottom of the anti-theft window 25, the upper end of the second escape ladder 29 is communicated with the second escape exit, and the lower end of the second escape ladder 29 extends to the upper end of the anti-theft window 25 on the next lower floor.

[0106] It should be noted that in the existing method of climbing directly on the anti-theft window, since it is a vertical climb, the center of gravity is all on the hips, making people very fatigued, the hands prone to soreness, the speed slow, and there is also fear of heights, and it is easy to fall, which is very unsafe. Therefore, in order to further improve the safety of climbing and reduce the difficulty of climbing, both the first escape ladder 28 and the second escape ladder 29 are inclined ladders, and the inclination angles of both are about 75°.

[0107] Embodiment 9:

[0108] This embodiment is optimized on the basis of the above Embodiment 8.

[0109] The second escape ladder 29 is a folding ladder. When the device is not in use, the folding ladder is in a folded state, and when the device is in use, the folding ladder is in an open state to achieve communication between adjacent floors.

[0110] Embodiment 10:

[0111] This embodiment is optimized on the basis of the above Embodiment 9.

[0112] After the personnel on this floor escape, in order to prevent the flames in the floor from further spreading and affecting the upper floors, a fireproof rolling curtain device 30 is further included, which is arranged inside the escape space 1 on this floor.

[0113] The fireproof rolling curtain device 30 of the fireproof rolling curtain 31 includes a fireproof rolling curtain 31, a reel 32 and a heat-melting wire 33. One end of the fireproof rolling curtain 31 is fixed to the upper end inside the escape space 1 on this floor, the other end of the fireproof rolling curtain 31 is fixed to the reel 32 and the fireproof rolling curtain 31 is wound on the reel 32, and the heat-melting wire 33 bundles and fixes the reel 32 wound with the fireproof rolling curtain 31 to the upper end inside the escape space 1 on this floor.

[0114] In case of a fire, the heat-melting wire 33 is melted by heat. Of course, the melting method of the heat-melting wire 33 can be electric heating melting, then the fireproof rolling curtain 31 moves down and unfolds under the action of gravity to prevent the further spread of flames and thick smoke.

[0115] In the above embodiments, a protective frame 34 is further provided on the first frame body 3. A plurality of through holes slidably matched with the second protective column 6 are provided on the protective frame 34. When the second protective main body is in the lowered state, the cross bar abuts against the protective frame 34.

[0116] The present invention is not limited to the above optional embodiments. Anyone can obtain other various forms of products under the inspiration of the present invention. However, no matter what changes are made in its shape or structure, as long as the technical solutions fall within the scope defined by the claims of the present invention, they all fall within the protection scope of the present invention.
