Description

Technical Field

[0001] This application relates to the field of rescue tools, and more specifically, to a user-friendly rescue guide rope. Background Technology

[0002] In the field of fire and rescue, rescue guide ropes are a crucial safety equipment, primarily used by firefighters in high-risk environments with extremely low visibility and easy disorientation, such as dense smoke, darkness, and complex building structures (e.g., basements, tunnels, ruins). Their main functions are to mark safe entry and exit routes, provide guidance for subsequent team members, and guide trapped personnel to a reliable route for rapid evacuation, while ensuring the rescuers themselves can safely return along the same path.

[0003] However, the traditional guide ropes or fluorescent guide ropes currently in common use have obvious limitations in practical applications: they cannot be installed quickly and reliably during use, nor can they be stored quickly, making them inconvenient to use. Summary of the Invention

[0004] The purpose of this application is to provide a rescue guide rope that is easy to use and can solve the above-mentioned technical problems.

[0005] This application provides a user-friendly rescue guide rope, including a housing, a mounting fastener, a coil spring, a telescopic rope, a hook, and a fixing ring. A mounting shaft is located in the center of the housing. The coil spring is installed inside the housing. The telescopic rope is spirally wound inside the housing. One end of the coil spring is fixedly connected to the mounting shaft, and the other end of the coil spring is fixedly connected to one end of the telescopic rope. An opening groove is provided on the side of the housing, and the other end of the telescopic rope extends from the opening groove to the outside of the housing. The hook is fixedly connected to the telescopic rope. One end of the mounting fastener is rotatably connected to one end of the back of the housing. A fastening post is provided at the other end of the back of the housing. A pin is provided between the mounting fastener and the fastening post. The fixing ring is located on one side of the housing.

[0006] Preferably, a clearance groove is provided between the mounting fastener and the housing, the width of the clearance groove being 5-8cm and the depth of the clearance groove being 0.3-0.8cm.

[0007] Preferably, the telescopic rope is provided with a memory steel wire inside, and a protective wire is wound around the outside of the memory steel wire, and a wear-resistant wire is wound around the outside of the protective wire.

[0008] Preferably, the memory steel is made of multiple memory wires wound together, and each memory wire has a reinforcing wire in the middle.

[0009] Preferably, the opening groove is provided with a through groove, the diameter of the through groove is smaller than the diameter of the telescopic rope, the through groove is elongated, and the opening groove is circular.

[0010] Preferably, a connecting ring is provided between the telescopic rope and the hook, and the memory steel wire extends into the connecting ring.

[0011] Preferably, a friction steel ball assembly is provided at the opening slot, and the friction steel ball assembly is installed at both ends of the telescopic rope.

[0012] Preferably, the friction ball assembly has multiple steel balls, and the surface of the steel balls has micro-protrusions.

[0013] Preferably, the surface of the housing is provided with a frosted layer, and the interior of the housing is provided with a reinforcing layer.

[0014] Preferably, the wear-resistant wire is coated with a fluorescent layer.

[0015] The beneficial effects of this invention are: This invention provides a user-friendly rescue guide rope, comprising a housing, a mounting fastener, a coil spring, a telescopic rope, a hook, and a fixing ring. A mounting shaft is located in the center of the housing. The coil spring is installed inside the housing. The telescopic rope is spirally wound inside the housing.

[0025] like Figure 1-3 As shown, a user-friendly rescue guide rope includes a housing 1, a mounting fastener 2, a coil spring 3, a telescopic rope 4, a hook 5, and a fixing ring 6. A mounting shaft 7 is located in the center of the housing 1. The coil spring 3 is installed inside the housing 1. The telescopic rope 4 is spirally wound inside the housing 1. One end of the coil spring 3 is fixedly connected to the mounting shaft 7, and the other end of the coil spring 3 is fixedly connected to one end of the telescopic rope 4. An opening groove 8 is provided on the side of the housing 1, and the other end of the telescopic rope 4 extends from the opening groove 8 to the outside of the housing 1. The hook 5 is fixedly connected to the telescopic rope 4. One end of the mounting fastener 2 is attached to the housing... One end of the back of the housing 1 is rotatably connected, and the other end of the back of the housing 1 is provided with a fastening post 9. A pin 10 is provided between the mounting fastener 2 and the fastening post 9. The fixing ring 6 is provided on one side of the housing 1. When in use, the present invention can be fixed to the rescuer's waist belt by the cooperation of the mounting fastener 2 and the fastening post 9, or fixed to the shoulder strap by the fixing ring 6. Then, the telescopic rope 4 can be pulled by the hook 5. When it is not necessary to pull, the telescopic rope 4 can be limited and fixed. When the rescue needs to be withdrawn, the limited fixation can be released, and the telescopic rope 4 can be retrieved by the coil spring 3, which facilitates the rescuer's quick evacuation, reduces safety risks, and optimizes the operating experience.

[0026] like Figure 1-3 As shown, in this embodiment, a clearance groove 11 is provided between the mounting fastener 2 and the housing 1. The width of the clearance groove 11 is 5-8cm and the depth of the clearance groove 11 is 0.3-0.8cm. The clearance groove 11 of the present invention facilitates the passage of a waist belt or shoulder strap. The clearance groove 11 of a suitable size can be selected according to the size of the waist belt or shoulder strap.

[0027] like Figure 1-3As shown in this embodiment, the telescopic rope 4 is internally provided with memory steel wire, and protective wire is wound around the outside of the memory steel wire. Wear-resistant wire is wound around the outside of the protective wire. The memory steel is made of multiple memory wires wound together, and a reinforcing wire is provided in the middle of each memory wire. The wear-resistant wire is coated with a fluorescent layer. The memory steel wire of the present invention makes it easy for the telescopic rope 4 to be wound inside the shell 1 when it is retrieved. The protective wire and wear-resistant wire can extend the service life of the telescopic rope 4. The fluorescent layer can reflect light, making it easier for other personnel to follow up on the rescue or to carry out rescue along different routes.

[0028] like Figure 1 As shown, in this embodiment, the opening groove 8 is provided with a through groove 12. The diameter of the groove 12 is smaller than the diameter of the telescopic rope 4. The groove 12 is elongated, and the opening groove 8 is circular. When it is necessary to limit and fix the telescopic rope 4, the telescopic rope 4 can be directly pulled into the groove 12 for locking. When it is necessary to retract, the telescopic rope 4 can be directly pulled into the opening groove 8 for retraction.

[0029] like Figure 1-2 As shown, in this embodiment, a connecting ring 13 is provided between the telescopic rope 4 and the hook 5, and the memory steel wire extends into the connecting ring 13. The connecting ring 13 of the present invention is integrally formed with the telescopic rope 4, which can improve the safety of the telescopic rope 4.

[0030] like Figure 3 As shown, in this embodiment, a friction steel ball assembly 14 is provided at the opening slot 8, and the friction steel ball assembly 14 is installed at both ends of the telescopic rope 4; a plurality of steel balls 15 are provided on the friction steel ball assembly 14, and the surface of the steel balls 15 is provided with micro protrusions; the friction steel ball assembly 14 of the present invention can improve the feel when pulling, and can appropriately increase the friction force to prevent the pulling rope from bouncing, and can transfer the tension of the coil spring 3.

[0031] In this embodiment, to prevent slippage during use and to increase the strength of the housing 1, a frosted layer is provided on the surface of the housing 1, and a reinforcing layer is provided inside the housing 1.
