DETAILED DESCRIPTION

[0029] The utility model will be explained in further detail in combination with the drawings. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the utility model in a schematic manner, so it only shows the structure related to the utility model.

[0030] In the description of the utility model, it should be explained that, unless otherwise explicitly specified and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or integrally connected, or mechanically connected, or electrically connected, or directly connected, or indirectly connected through an intermediate medium. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0031] Figs. 1-4The escape rope ladder shown includes two main rope ladder bodies 1 and two hooks 4. Several steps 5 are fixedly connected between the two main rope ladder bodies 1. An adjustment device 2 is provided between one end of each main rope ladder body 1 and the two hooks 4. An anti-slip device 3 is provided on the outer surface of each step 5. The adjustment device 2 includes a through-hole rod 21 and a bolt 27. One side of the through-hole rod 21 is fixedly connected to one end of each main rope ladder body 1. Rectangular holes 22 are symmetrically opened on one side of the inner wall of the through-hole rod 21. The system has several threaded grooves 23. The inner wall of the through-hole rod 21 is symmetrically connected to a toothed plate 24. A gear 25 is inserted through one side of the inner wall of the rope ladder body 1. The outer surface of the gear 25 meshes with one side of the toothed plate 24. A screw hole block 26 is fixedly connected to one side of the gear 25. One end of the bolt 27 is screwed into the inner wall of the screw hole block 26 and the threaded groove 23. One side of the toothed plate 24 is rotatably connected to one end of the hook 4. Both the toothed plate 24 and the hook 4 are slidably connected to the inner wall of the rectangular hole 22. When using an escape rope ladder for escape, depending on the environment of the escape site and the location for fixing, manually hold the screw hole block 26 and rotate its gear 25 a certain number of turns in the inner wall of the through hole rod 21. This will cause the two toothed plates 24 to slide in opposite directions to a certain position in the inner wall of the through hole rod 21, adjusting the distance between the two hooks 4. After adjustment, screw the bolt 27 into the inner wall of the screw hole block 26 and then screw it into the inner wall of the corresponding threaded groove 23 to fix the adjusted hooks 4. This allows the hooks 4 to be easily suspended and fixed according to the environment of the escape site, facilitating the installation of the rope ladder body 1 and the step bar 5, improving adaptability, and making it easier to use.

[0032] Figs. 1-4 One end of the bolt 27 is fixedly connected to a connecting rope 28, and the other end of the connecting rope 28 is fixedly connected to one side of the threaded block 26. By providing the connecting rope 28, the bolt 27 can be confined to one side of the threaded block 26, preventing it from being lost after being screwed out of the threaded block 26 and the inner wall of the threaded groove 23. Several protrusions 29 are fixedly connected to the outer surface of the threaded block 26, and these protrusions 29 are arranged at equal intervals. By providing the protrusions 29, the contact area of ​​the outer surface of the threaded block 26 can be increased, making it easier to manually grip and screw it.

[0033] Figs. 1-4A bearing 210 is fixedly connected to the outer surface of one end of the hook 4 shown. The outer ring of the bearing 210 is fixedly connected to one side of the toothed plate 24. By setting the bearing 210, the rotational wear between the toothed plate 24 and the hook 4 can be reduced, making it easier for the hook 4 to rotate and improving the service life of both. A limit block 211 is fixedly connected to one side of the toothed plate 24, and limit grooves 212 are opened on both sides of the inner wall of the through-hole rod 21. The limit block 211 is slidably connected to the limit grooves 212. By setting the limit block 211 and the limit grooves 212, one side of the toothed plate 24 can be limited, making it less likely to wobble when sliding back and forth in the inner wall of the through-hole rod 21.

[0034] Figs. 1-4 The anti-slip device 3 shown includes a pedal 31, one side of which is fixedly connected to one side of the step bar 5. Several circular blocks 33 are threaded through and connected to one side of the pedal 31, and a spring 32 is fixedly connected to one side of each circular block 33. One end of the spring 32 is fixedly connected to one side of the inner wall of the pedal 31. When using the escape rope ladder, the pedal 31 can increase the stepping area of ​​the step bar 5, making it easier to step on more stably. When a person steps on the pedal 31, the circular blocks 33 at the stepping position will retract into the interior of the pedal 31, causing the spring 32 to contract. Meanwhile, the circular blocks 33 around the foot will remain stationary to limit the foot's movement, and also limit movement according to the shape of the shoe to prevent slipping, making the step more secure and improving the safety of using the escape rope ladder.

[0035] Figs. 1-4 A telescopic rod 34 is fixedly connected to one side of the circular block 33. One end of the telescopic rod 34 is fixedly connected to the inner wall of the pedal 31, and the outer surface of the telescopic rod 34 is sleeved and connected to the inner wall of the spring 32. By setting the telescopic rod 34, the inner wall of the spring 32 can be supported and reinforced, making it less prone to damage during use and extending its service life. Several reinforcing rods 35 are symmetrically fixedly connected to one side of the pedal 31. One side of the reinforcing rod 35 is fixedly connected to one side of the foot lever 5. By setting the reinforcing rods 35, the connection area between the foot lever 5 and the pedal 31 can be increased, making the connection more secure and stable, and less prone to breakage and damage.

[0036] Working principle: When using the escape rope ladder for escape, depending on the environment of the escape site and the location to be fixed, manually hold the screw hole block 26 and rotate its gear 25 in the inner wall of the through hole rod 21 a certain number of turns. This will drive the two toothed plates 24 and the limiting block 211 to slide in opposite directions to a certain position in the inner walls of the through hole rod 21 and the limiting groove 212, respectively. This will adjust the distance between the two hooks 4. After adjustment, screw the bolt 27 into the inner wall of the screw hole block 26 and then screw it into the inner wall of the corresponding threaded groove 23. This will facilitate the fixing of the adjusted hooks 4, allowing them to be easily suspended and fixed according to the environment of the escape site. This also facilitates the installation of the rope ladder body 1 and the step bar 5, improves adaptability, and makes it easier to use.

[0037] When using the escape rope ladder, the step plate 31 increases the stepping area of ​​the step bar 5, making it easier to step on more stably. When a person steps on the step plate 31, the circular block 33 at the stepping position will retract into the interior of the step plate 31, causing the spring 32 to contract. Meanwhile, the circular blocks 33 around the foot will remain stationary to limit the foot's movement and, based on the shape of the shoe, prevent slippage, making the step more secure and improving the safety of using the escape rope ladder.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
