Description

Technical Field

[0001] This utility model relates to the technical field of rescue rope protective sleeves, and in particular to a wear-resistant protective sleeve for rescue ropes. Background Technology

[0002] Abrasion-resistant protective sleeves for rescue ropes are devices used to protect rescue ropes from abrasion, scratches, and other external damage during high-intensity rescue missions. When used in complex environments, such as rock rescue, fire rescue, and mountain rescue, rescue ropes often come into contact with rough surfaces, sharp objects, and high-friction conditions, thus requiring an extra layer of protection. Protective sleeves are typically made of abrasion-resistant, high-temperature-resistant, and impact-resistant materials, effectively extending the service life of the rescue rope.

[0003] However, existing rescue rope protective sleeves have some shortcomings in use, especially when adapting to rescue ropes of different specifications. Traditional protective sleeve designs usually use a fixed inner diameter, which cannot be flexibly adjusted according to the diameter of the rescue rope or the needs of use. Due to the size differences of different rescue ropes, protective sleeves with a fixed inner diameter cannot adapt to ropes of various specifications. This results in the protective sleeve not fitting tightly to the rope in some cases, thus affecting its protective effect. Therefore, we propose this utility model. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a wear-resistant protective sleeve for rescue ropes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wear-resistant protective sleeve for a rescue rope includes a protective layer wound around the outer wall of the rescue rope body. The outer wall of the protective layer is provided with an installation structure. The installation structure includes a plurality of snap-fit ​​holes formed on the top surface of the protective layer. A plurality of snap-fit ​​shafts are fixed on the top surface of the protective layer. The plurality of snap-fit ​​shafts are evenly distributed along the length direction of the protective layer. The diameter of the snap-fit ​​holes is larger than the diameter of the snap-fit ​​shafts. Movable shafts are slidably inserted on both sides of the snap-fit ​​shafts. A spring is fixed between two movable shafts.

[0007] As a further embodiment of this utility model, a textured surface layer is fixed to the top surface of the protective layer, and a hooked surface layer is fixed to the bottom surface of the protective layer.

[0008] As a further embodiment of this invention, a buffer layer is fixed inside the protective layer, and the buffer layer is made of EVA material.

[0009] As a further embodiment of this utility model, a tensile layer is fixed between the buffer layer and the protective layer, and the tensile layer is made of Kevlar material.

[0010] As a further embodiment of this utility model, a metal ring is fixed inside the snap-fit ​​hole, and the inner diameter of the metal ring is the same as the diameter of the snap-fit ​​shaft.

[0011] As a further embodiment of this utility model, the movable shaft consists of two columns with different diameters.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This protective sleeve, through its installation structure, allows the user to adhere the rough surface layer to the outer wall of the rescue rope before wrapping the protective layer around it. During winding, the rough surface layer adheres to the hook surface layer, initially installing the protective layer onto the rescue rope. After winding, the locking shaft is inserted into the locking hole, and the movable shaft is limited by a spring to prevent it from dislodging, thus ensuring a secure installation. The winding method enhances the protective effect and increases the sleeve's adaptability to different sizes of rescue ropes. The nylon protective layer also improves wear resistance.

[0022] Reference Figures 1-4 A wear-resistant protective sleeve for a rescue rope includes a protective layer 2 wound around the outer wall of the rescue rope body 1. The outer wall of the protective layer 2 is provided with an installation structure, which includes a plurality of snap-fit ​​holes 201 formed on the top surface of the protective layer 2. A plurality of snap-fit ​​shafts 202 are fixed on the top surface of the protective layer 2. The plurality of snap-fit ​​shafts 202 are evenly distributed along the length direction of the protective layer 2. The diameter of the snap-fit ​​holes 201 is larger than the diameter of the snap-fit ​​shafts 202. Movable shafts 203 are slidably inserted on both sides of the snap-fit ​​shafts 202. A spring 204 is fixed between two movable shafts 203. The protective layer 2 is made of nylon and has good wear resistance.

[0023] In this embodiment, a rough surface layer 205 is fixed to the top surface of the protective layer 2, and a hook surface layer 206 is fixed to the bottom surface of the protective layer 2. Through the installation structure, when using the protective cover, the user can tightly fit the rough surface layer 205 against the outer wall of the rescue rope body 1, and then wrap the protective layer 2 around the rescue rope body 1, thereby providing effective protection for the rescue rope body 1. When the protective layer 2 is wound around the rescue rope body 1, the rough surface layer 205 and the hook surface layer 206 adhere to each other, initially fixing the protective layer 2 onto the rescue rope body 1. After winding, the locking shaft 202 is inserted into the corresponding locking hole 201, and the movable shaft 203 is supported by the spring 204. The locking pin 202 is limited by the action of the locking pin 202 to prevent it from coming out of the locking hole 201, thereby achieving a stable installation of the protective sleeve on the rescue rope body 1. The winding and wrapping method not only ensures the stability of the protective layer 2, but also makes the protective layer 2 fit more tightly with the rescue rope body 1, improving the protection effect. In addition, this design enhances the adaptability of the protective sleeve to rescue rope bodies 1 of different specifications, and can be flexibly adjusted to adapt to ropes of various diameters, especially suitable for changing rescue environments. At the same time, the use of nylon material for the protective layer 2 enhances its wear resistance, effectively resists external friction, extends the service life of the protective sleeve, and improves the protection effect.

[0024] In this embodiment, a buffer layer 3 is fixed inside the protective layer 2. The buffer layer 3 is made of EVA material. The buffer layer 3 can improve the overall protection effect of the protective sleeve rescue rope body 1 through its good flexibility and elasticity.

[0025] In this embodiment, a tensile layer 4 is fixed between the buffer layer 3 and the protective layer 2. The tensile layer 4 is made of Kevlar material. The tensile layer 4 can improve the tensile strength of the protective sleeve and prevent the protective sleeve from deforming or breaking under extreme tension or pressure.

[0026] In this embodiment, a metal ring 5 is fixed inside the snap-fit ​​hole 201. The inner diameter of the metal ring 5 is the same as the diameter of the snap-fit ​​shaft 202. The metal ring 5 can protect the snap-fit ​​hole 201.

[0027] In this embodiment, the movable shaft 203 consists of two columns with different diameters. The movable shaft 203 is composed of two main bodies with different diameters to prevent the movable shaft 203 from coming out of the snap-fit ​​shaft 202.

[0028] Working principle: When installing the protective sleeve on the rescue rope body 1, the rough surface layer 205 can be tightly fitted to the outer wall of the rescue rope body 1. Then, the protective layer 2 is wrapped around the rescue rope body 1, thus providing effective protection for the rescue rope body 1. When the protective layer 2 is wound around the rescue rope body 1, the rough surface layer 205 and the hook surface layer 206 adhere to each other, initially fixing the protective layer 2 to the rescue rope body 1. After winding, the locking shaft 202 is inserted into the corresponding locking hole 201. The movable shaft 203, under the action of the spring 204, limits the locking shaft 202, preventing the locking shaft 202 from coming out of the locking hole 201, thereby achieving a stable installation of the protective sleeve on the rescue rope body 1. The wrapping method not only ensures the stability of the protective layer 2, but also allows it to fit more tightly to the rescue rope body 1, improving the protective effect. In addition, this design enhances the adaptability of the protective sleeve to different specifications of the rescue rope body 1, allowing for flexible adjustment to accommodate ropes of various diameters, making it particularly suitable for varied rescue environments. Meanwhile, the use of nylon material for the protective layer 2 enhances its abrasion resistance, and the buffer layer 3, with its good flexibility and elasticity, improves the overall protective effect of the protective sleeve on the rescue rope body 1. The tensile layer 4 increases the tensile strength of the protective sleeve, preventing deformation or breakage under extreme tension or pressure. The metal ring 5 protects the snap-fit ​​hole 201.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
