Description

Technical Field

[0001] The invention specifically relates to a high-rise building fire escape ladder and belongs to the technical field of escape ladders. Background Art

[0002] As cities develop more and more rapidly, residential buildings and office buildings are springing up, and people are paying more and more attention to the problem of building fire escape. When an indoor fire is discovered late or develops very quickly, the escape probability of indoor personnel will decrease rapidly. Conventional safety passages are often attacked by fire, making it impossible for people to escape safely. The escape speed of people through stairwells is reduced, and for people working in high-rise buildings, they can only escape through stairs when a fire occurs. For high-rise buildings such as office buildings or commercial buildings, if the middle of the floor is blocked, people on the upper floors cannot escape, and an escape ladder is needed to help escape. However, a general escape ladder does not have a pedal, which makes it easy for users to slip when escaping. The safety of the ladder is reduced, causing irreversible harm to the physical and mental health of users, and it is inconvenient to use and has low practicality. Summary of the invention

[0003] The purpose of the present invention is to provide a high-rise building fire escape ladder to address the deficiencies of the prior art, which has the advantage of improving the safety of the ladder and at the same time, can store the retractable pedal assembly to facilitate the carrying and use of the ladder.

DETAILED DESCRIPTION OF THE INVENTION

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. 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 protection scope of the present invention.

[0014] Please refer to Figures 1-3 As shown, a fire escape soft ladder for high-rise buildings includes a fireproof isolation board 1, a fireproof sleeve 2, a winding rod 3, a clamping plate 4, a heat-resistant telescopic rod 5, a heat-resistant strong suction cup 6, a soft ladder frame 7, a retractable pedal assembly 8, a lower handrail 9, an upper handrail 10, and a fireproof rope 11. The bottom of the fireproof sleeve 2 is fixedly installed on the top of the fireproof isolation board 1 to protect the fireproof rope 11. The bottom of the winding rod 3 is fixed inside the fireproof sleeve 2, and the fireproof rope 11 is wound around the outside of the winding rod 3 to prevent the fireproof rope 11 from being wound together and facilitate the next use of the fireproof rope 11. The fireproof rope 11 is located inside the fireproof sleeve 2. One side of the soft ladder frame 7 is fixed to the front side of the fireproof isolation board 1 for installing the retractable pedal assembly 8 and the lower handrail 9. The cooperation of the user's hands and feet makes the escape soft ladder safer. The retractable pedal assembly 8 is installed through both sides of the soft ladder frame 7.

[0015] The top of the clamping plate 4 is fixed to the bottom of the fireproof isolation board 1 to fix the heat-resistant telescopic rod 5 for convenient fixing and clamping. One end of the heat-resistant telescopic rod 5 is fixedly installed on the front side of the clamping plate 4, and one side of the heat-resistant strong suction cup 6 is installed at the other end of the heat-resistant telescopic rod 5. The heat-resistant strong suction cup 6 can adsorb on the wall and act together with the fireproof rope 11. Both ends of the lower handrail 9 are fixedly installed on both sides of the soft ladder frame 7, and both ends of the upper handrail 10 are fixedly installed on the top of the fireproof isolation board 1 to facilitate the user's feet to be smoothly placed on the retractable pedal assembly 8. The upper handrail 10 and the bottom of the fireproof sleeve 2 are on the same plane.

[0016] When the present invention is actually used, the user places the fireproof isolation board 1 of the escape soft ladder at the window. Then, the heat-resistant telescopic rod 5 stretches to drive the heat-resistant strong suction cup 6 to move forward. When the heat-resistant strong suction cup 6 adsorbs to the wall, the heat-resistant telescopic rod 5 stops stretching. Then, the fireproof rope 11 is taken out from the inside of the fireproof sleeve 2 and fixed at the window, so that the fixing effect of the escape soft ladder is better. After the fireproof isolation board 1 is fixed, the soft ladder frame 7 is placed outside the window. The retractable pedal assembly 8 can be unfolded under the action of gravity, which is convenient for the user to use. The retractable pedal assembly 8 increases the load-bearing area of the feet and improves the safety of using the soft ladder. Finally, the user escapes by placing the hands on the upper handrail 10 and the feet on the retractable pedal assembly 8. When moving on the retractable pedal assembly 8, the hands are placed on the lower handrail 9, so that the hands and feet of the user can cooperate and the use is more convenient. After the user has used it and eliminated potential safety hazards, the heat-resistant telescopic rod 5 contracts to drive the strong suction cup away from the wall. Then, the fireproof rope 11 is removed and wound around the outside of the winding rod 3 for convenient use next time. The soft ladder frame 7 is inverted, and the retractable pedal assembly 8 can move between the two soft ladder frames 7 by gravity, which is convenient for storage and carrying.

[0017] As a technical optimization scheme of the present invention, the retractable pedal assembly 8 includes a pin shaft one 801, a pedal 802, an anti-slip protrusion 803, a lower fixing ring 804, a lower connecting ring 805, a folding connecting rod 806, a pin shaft two 807, an upper connecting ring 808, and an upper fixing ring 809. The pin shaft one 801 is installed through both sides of the soft ladder frame 7 so that the pedal 802 can rotate. One end of the pedal 802 is rotatably installed outside the pin shaft one 801. The pedal 802 is located inside the soft ladder frame 7. The bottom of the anti-slip protrusion 803 is fixedly arranged on the top of the pedal 802, which improves the safety of the escape soft ladder.

[0018] Both ends of the lower fixing ring 804 are fixed on both sides of the pedal 802. The lower connecting ring 805 is installed through the inside of the lower fixing ring 804 for connecting the lower fixing ring 804 and the pedal 802. The bottom of the folding connecting rod 806 is fixed on the lower connecting ring 805. The pin shaft two 807 is installed through the middle of the folding connecting rod 806 to facilitate the folding of the folding connecting rod 806. Both ends of the upper fixing ring 809 are fixed on the rear side of the soft ladder frame 7. The upper connecting ring 808 is installed through the inside of the upper fixing ring 809 for connecting the upper fixing ring 809 and the soft ladder frame 7. The top of the folding connecting rod 806 is fixed on the upper connecting ring 808. The upper fixing ring 809 and the lower fixing ring 804 can fix the position of the folding connecting rod 806, so that the soft ladder frame 7, the pedal 802, and the folding connecting rod 806 form a stable triangular structure.

[0019] When the present invention is in use, the retractable pedal assembly 8 relies on its own gravity to enable the folding link 806 to unfold, so that the pedal 802 can be perpendicular to the soft ladder frame 7, facilitating the placement of the user's feet. Anti-slip protrusions 803 are evenly arranged on the top of the pedal 802 to prevent the user's feet from getting wet and slipping, which may cause harm to the physical and mental health of the user. After use, the retractable pedal assembly 8 relies on its own gravity again to enable the folding link 806 to fold, so that the pedal 802 can coincide with the soft ladder frame 7, facilitating the storage and carrying of the emergency escape soft ladder.

[0020] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
