Description

Technical Field

[0001] This invention relates to the field of fire escape technology, specifically to a fixed fire escape box for use outside windows in high-rise buildings. Background Technology

[0002] Fixed window-mounted fire escape boxes are self-rescue and escape devices used in emergencies such as fires in high-rise buildings. Their core function is to help trapped individuals safely descend from high-rise buildings to the ground using slow-descent technology. A search reveals Chinese Patent Publication No. CN213466547U, which discloses a continuous slow-descent escape device for high-rise fires, belonging to the field of fire-fighting equipment technology. This device includes a slow-descent mechanism. When used by escapees, the slow-descent mechanism effectively avoids vertical windows, reducing obstacles on the escape route and thus improving safety. A sliding ring keeps the slow-descent mechanism away from windows, preventing damage to the safety rope due to high temperatures and further enhancing safety. However, existing technologies have the following drawbacks: the rope slow-descent mechanism lacks an effective limiting and protective structure, leading to significant swinging and even wall collisions during descent, exacerbating panic and affecting usability. Furthermore, securing the escapee with an escape rope is less safe and requires significant physical strength. Therefore, this paper proposes a fixed window-mounted fire escape box for high-rise buildings to address these issues. Summary of the Invention

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a fixed fire escape box outside the window for high-rise buildings, which has the following advantages:

[0018] 1. This fixed fire escape box for high-rise buildings features an escape mechanism. The curved plate in the escape mechanism is fixedly connected to the bottom of the connecting rope. The protective vest is fixed to the bottom of the curved plate. When a person puts on the protective vest, the elastic band can be adjusted for comfort. The fixing strap is wrapped around the body and fixed by the hook and loop fasteners. The airbag can provide a certain degree of cushioning and protection during the escape process.

Compared with ropes, the protective vest is more convenient for escapers to use, achieving a higher level of escape safety.

[0019] 2. This fixed fire escape box for high-rise buildings, installed with a protective mechanism, ensures that during the descent of the escape mechanism, the moving wheels first contact the wall or other supporting structure. The wheels roll during descent, reducing friction and making the descent smoother. The length of the extending connecting column can be adjusted as needed. Pushing the push plate inward compresses the connecting spring and simultaneously causes the locking block to disengage from the slot on the outer cylinder. At this point, the U-shaped frame, connecting column, and moving cylinder can be moved to the desired position. Releasing the push plate allows the locking block to engage with the slot under the action of the connecting spring, completing the fixation and achieving the purpose of preventing collisions with the limit protection structure.

The upper and lower outer frames 52 are located on the upper and lower sides of the rectangular holes 51, respectively. A U-shaped plate 53 that fits against the box body 4 is slidably installed between the inner sides of the upper and lower outer frames 52. Under the action of the telescopic spring 54, it can move relative to the box body 4, thereby driving the connecting block 55 and the limiting cylinder 56 to move, thereby adjusting the position of the limiting cylinder 56 and limiting the connecting rope 64. A telescopic spring 54 that is fixedly connected to the inner wall of the rectangular hole 51 is fixedly installed on the inner side of the U-shaped plate 53. A connecting block 55 is fixedly installed on the opposite side of the two U-shaped plates 53. A limiting cylinder 56 is fixedly installed between the two connecting blocks 55.

[0035] The limiting cylinder 56 is designed to be flexible, and there are two sets of limiting components 5, which can reduce wear on the connecting rope 64 and limit the sway range of the connecting rope 64, making the connecting rope 64 more stable during lifting.

[0036] The lifting assembly 6 includes a servo motor 61. The servo motor 61 is fixedly installed on the left side of the inner wall of the box 4, serving as the power source for the lifting assembly 6 and providing power for the rotation of the rotating shaft 62. This drives the winding drum 63 to perform winding and unwinding operations on the connecting rope 64. The output shaft of the servo motor 61 is fixedly installed with the rotating shaft 62, which is rotatably connected to the right side of the inner wall of the box 4. Two winding drums 63 are fixedly installed on the outer side of the rotating shaft 62. By rotating the rotating shaft 62, the winding and unwinding operations of the connecting rope 64 are realized, thereby controlling the lifting and lowering of the escape mechanism 7. The connecting rope 64 is wound around the outer side of the winding drum 63. Two stabilizing wheels 65 are fixedly installed on the inner top wall of the box 4 to make the connecting rope 64 move more smoothly during lifting and lowering and reduce swaying. One end of the connecting rope 64 passes around the stabilizing wheel 65, passes through the limiting cylinder 56, and extends to the bottom of the outer box 1. The strip hole 9 is located on the outer side of the connecting rope 64, and the protective strip 10 is attached to the connecting rope 64.

[0037] The escape mechanism 7 includes an arc-shaped plate 71. An arc-shaped plate 71 is fixedly installed at the bottom of the connecting rope 64. A protective vest 72 is fixedly installed between the bottoms of the two arc-shaped plates 71. Personnel wear the protective vest 72 to escape. An elastic band 73 is fixedly installed between the left and right sides of the inner wall of the protective vest 72. Airbags 74 are movably installed on both the front and back sides of the protective vest 72. The airbags 74 can reduce the impact force and protect the safety of personnel. A fixing strap 75 extending to the back side is fixedly installed on the front side of the protective vest 72. A Velcro loop side 76 is fixedly installed on the back side of the protective vest 72. A Velcro barbed side 77 that fits into the Velcro loop side 76 is fixedly installed on the inner side of the fixing strap 75.

[0038] The protective vest 72 has two mounting holes on its inner bottom wall, four single-sided airbags 74 in pairs, and a protective pad on the inner side of the arc plate 71 to increase the comfort of the user.

[0039] The protective mechanism 8 includes an outer cylinder 801. The outer cylinder 801 is fixedly installed on the rear side of the arc-shaped plate 71. Limiting frames 802 are fixedly installed on the inner walls of the opposite sides of the two outer cylinders 801. A movable cylinder 803 located inside the outer cylinder 801 is slidably installed on the inner side of the limiting frame 802. A return spring 804 fixedly connected to the front side of the inner wall of the outer cylinder 801 is fixedly installed on the inner side of the movable cylinder 803. A connecting post 805 extending to the rear side of the outer cylinder 801 is fixedly installed on the rear side of the movable cylinder 803. A U-shaped frame 806 extending to the rear side is slidably installed between the opposite sides of the two outer cylinders 801. The U-shaped frame 806 is fixedly connected to the rear side of the connecting post 805. A set of casters 807 is fixedly installed on the rear side of the frame 806. During the descent of the escape mechanism, the casters 807 first contact the wall and roll, reducing friction and making the descent smoother. At the same time, the protective mechanism 8 as a whole can play a buffering and stabilizing role, effectively preventing personnel from colliding with the wall. A base plate 808 located outside the outer cylinder 801 is fixedly installed between the two moving cylinders 803. An installation box 809 is fixedly installed on the top of the base plate 808. Two push plates 810 extending to the top of the installation box 809 are slidably installed on the inner side of the installation box 809. By pushing the push plates 810, the extension and retraction of the locking blocks 811 can be controlled, realizing the engagement and disengagement of the protective mechanism 8 with the outer cylinder 801. The outer foam cover can increase the comfort during operation. Locking blocks 811 extending to the outside of the installation box 809 and engaging with the two outer cylinders 801 are fixedly installed on the opposite sides of the two push plates 810. A connecting spring 812 located inside the installation box 809 is fixedly installed between the two push plates 810.

[0040] The inner wall of the outer cylinder 801 has a through hole that matches the connecting post 805. The number of moving wheels 807 can be set according to the requirements and they are evenly distributed from left to right. The inner wall of the mounting box 809 has through holes that match the locking block 811 on both the left and right sides. The two outer cylinders 801 have slots on opposite sides. The size of the slots matches the locking block 811. The outer side of the push plate 810 is covered with a sponge sleeve.

[0041] In use, fix the mounting plate 2 to the exterior wall of a window in a suitable location on a high-rise building, ensuring the outer box 1 is securely installed. Check all components for damage, including the servo motor 31, servo motor 61, connecting rope 64, and airbag 74, ensuring there is no damage or looseness. Open the door of the storage box 11 and check for any debris inside, ensuring the storage box 11 is clean. Based on the actual escape location, start the servo motor 31 and adjust the horizontal position of the box 4 and the entire escape and protection mechanisms using the moving component 3, so that the escape mechanism is roughly in the appropriate position. Put on the protective vest 72, adjust the elastic band 73, and secure the fixing strap 75. Start the servo motor 61 to allow the lifting component 6 to begin releasing the cable, and the escape mechanism 7 slowly... During descent, the moving wheels 807 contact and roll against the wall, while the protective mechanism 8 acts as a buffer and stabilizer. Personnel control the descent speed by adjusting the rotation speed of the servo motor 61, slowly descending to a safe position. After the personnel have escaped, the servo motor 61 is activated to rotate in the reverse direction, causing the lifting component 6 to retract its cable and raising the escape mechanism 7 back to its original position. The protective vest 72 and other components are then neatly arranged and placed in the storage box 11, and the box door is closed for future use. The fire escape box should be inspected regularly, including checking the operation of the servo motors 31 and 61, whether the connecting rope 64 is worn, and whether the airbag 74 is leaking. All moving parts should be lubricated and maintained to ensure smooth operation of the moving component 3, lifting component 6, protective mechanism 8, and other components.

[0042] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0043] In summary, this fixed fire escape box for high-rise buildings, installed with an escape mechanism 7, features an arc-shaped plate 71 fixedly connected to the bottom of a connecting rope 64. A protective vest 72 is fixed to the bottom of the arc-shaped plate 71. Personnel wearing the vest 72 adjust comfort using the elastic band 73, wrap the fixing strap 75 around their body, and secure it using the Velcro hook side 77 and Velcro loop side 76. The airbag 74 provides cushioning and protection during escape. In case of an accident during descent, the airbag 74 reduces impact. Compared to ropes, the protective vest 72 is more convenient for escapers, achieving a higher level of escape safety. By incorporating a protective mechanism 8, during the descent of the escape mechanism 7, the moving wheels 807 first contact the wall or other supporting structures. During descent, the moving wheels 807 can... The rolling mechanism reduces friction, making descent smoother. The length of the connecting column 805 can be adjusted as needed. Pushing the push plate 810 inward compresses the connecting spring 812, simultaneously causing the locking block 811 to disengage from the slot on the outer cylinder 801. At this point, components such as the U-shaped frame 806, connecting column 805, and moving cylinder 803 can be moved to the appropriate position. Once the position is reached, the push plate 810 is released, and under the action of the connecting spring 812, the locking block 811 engages with the slot, completing the fixation. This achieves the purpose of having a limit protection structure to prevent collisions, solving the problems of rope descent devices without an effective limit protection structure, which are prone to large swings or even wall collisions during descent, exacerbating panic among escapees and affecting usability. Furthermore, fixing escapees with escape ropes is less safe and requires a high level of physical strength from the escapees.
