Description

Technical Field

[0001] This utility model belongs to the field of parachute technology, specifically relating to a lightweight, highly tear-resistant parachute rope and canopy composite structure. Background Technology

[0002] Parachutes, as a commonly used aviation device, are widely used in aviation, aerospace, military, rescue and other fields. The core components of a parachute include the canopy, parachute lines and parachute accessories. The canopy is responsible for forming the canopy, supporting the parachute's flight attitude in the air and providing sufficient buoyancy. The parachute lines connect the canopy to the lander, playing a role in transmitting tension and ensuring the stable deployment of the parachute.

[0003] A prior art patent, CN219137254U, describes a fire-resistant parachute rope. This patent includes an aramid outer braided fire-resistant sheath and an inner core rope disposed within the sheath. The inner core rope comprises an aramid inner braided fire-resistant core rope, with reinforcing steel wire ropes on its inner side. A rubber-plastic wear-resistant sleeve is fitted over the outer side of the aramid inner braided fire-resistant core rope. Multiple aramid inner braided fire-resistant core ropes are disposed within the inner side of the aramid outer braided fire-resistant sheath. The inner side of the rope is reinforced with steel wire rope... This device, through the multi-core structure of the parachute rope, allows for lengthening of the parachute rope by cutting it open and pulling out the inner core when used outdoors if the length of a single rope is insufficient, thus facilitating emergency use. However, in actual use, the following shortcomings still exist: In practice, when the parachute deploys rapidly or contacts the ground, it is easily affected by physical impacts or wind. The device's tear resistance is insufficient, which can easily lead to tearing of the canopy and parachute rope, thereby affecting the overall function and safety of the parachute.

[0004] Therefore, a lightweight, highly tear-resistant parachute cord and fabric composite structure is needed to solve the problem of insufficient tear resistance of parachute cords and fabric in existing technologies. Utility Model Content

[0005] The purpose of this invention is to provide a lightweight, highly tear-resistant parachute rope and canopy composite structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lightweight, highly tear-resistant parachute rope and canopy composite structure, comprising a canopy, an anti-tipping net fixedly connected to the bottom of the canopy, a plurality of connecting rings fixedly connected to the bottom of the anti-tipping net, and parachute ropes fixedly connected to the bottom of each of the plurality of connecting rings.

[0007] It should be noted in the solution that the umbrella fabric includes a tear-resistant layer, an intermediate functional reinforcement layer is fixedly connected to the inner wall of the tear-resistant layer, a flexible support layer is fixedly connected to the inner wall of the intermediate functional reinforcement layer, an anti-ultraviolet protection layer is fixedly connected to the inner wall of the flexible support layer, and an inner waterproof layer is fixedly connected to the inner wall of the anti-ultraviolet protection layer.

[0008] It is worth noting that the tear-resistant layer is made of Kevlar, the intermediate functional reinforcement layer is made of high-strength polyethylene, the flexible support layer is made of polyurethane, the UV-resistant protective layer is made of UV-protective coating, and the inner waterproof layer is made of polytetrafluoroethylene film.

[0009] It should be further noted that the multiple connecting rings are evenly distributed in a circular symmetrical pattern at the bottom of the anti-tipping net.

[0010] In a preferred embodiment, the paracord includes an outer sheath, a tensile filler fixedly connected to the inner wall of the outer sheath, a plurality of first reinforcing ribs fixedly connected to the inner wall of the tensile filler near its edge, an elastic layer fixedly connected to the center of the inner wall of the tensile filler, a fireproof layer fixedly connected to the inner wall of the elastic layer, a load-bearing layer fixedly connected to the inner wall of the fireproof layer, a plurality of second reinforcing ribs fixedly connected to the inner wall of the load-bearing layer near its edge, and a main rope core fixedly connected to the center of the inner wall of the load-bearing layer.

[0011] In a preferred embodiment, the outer sheath is made of polyester fiber, the tensile filler is made of aramid fiber, the first reinforcing rib is made of stainless steel wire, the elastic layer is made of polyurethane, the fireproof layer is made of flame-retardant polyester fiber, the load-bearing layer is made of polyethylene, the second reinforcing rib is made of acrylic fiber, and the main rope core is made of high-strength polyethylene.

[0012] In a preferred embodiment, the umbrella fabric, anti-tipping net, connecting ring, and umbrella ropes are all fixedly connected by high-strength stitching.

[0013] Compared with the prior art, the lightweight and highly tear-resistant parachute rope and canopy composite structure provided by this utility model has at least the following beneficial effects:

[0014] (1) By combining a tear-resistant layer, an intermediate functional reinforcement layer, a flexible support layer, an anti-ultraviolet protective layer, and an inner waterproof layer, the parachute fabric can have excellent tear resistance, abrasion resistance, flexibility, anti-ultraviolet properties, and waterproofness, ensuring that the parachute can still perform well under extreme weather conditions, improving safety and extending service life. This multi-layer structure design enables the parachute to exhibit higher reliability and durability when facing different environmental challenges.

[0015] (2) By setting up a multi-layer composite structure for the parachute ropes, a variety of high-strength materials such as aramid, polyethylene, and stainless steel wire are used, which makes the parachute ropes have extremely high tensile strength. Under the conditions of rapid descent of the parachute and strong wind and impact, the parachute ropes can withstand a large amount of tension, ensuring that the parachute canopy can be stably deployed and work normally. At the same time, the inner elastic layer can have a certain degree of extensibility and buffering when it is subjected to tension, which helps to disperse sudden impact force and avoid damage to the parachute ropes or deformation of the parachute canopy due to excessive instantaneous tension when the parachute opens, thus ensuring smooth deployment and stability during the descent.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] Please see Figure 1-3 This utility model provides a lightweight, highly tear-resistant parachute rope and canopy composite structure, including a canopy 1, an anti-tipping net 2 fixedly connected to the bottom of the canopy 1, a plurality of connecting rings 3 fixedly connected to the bottom of the anti-tipping net 2, and parachute ropes 4 fixedly connected to the bottom of each of the plurality of connecting rings 3.

[0022] Further as Figure 2As shown, it is worth noting that the parachute fabric 1 includes a tear-resistant layer 101, an intermediate functional reinforcement layer 102 fixedly connected to the inner wall of the tear-resistant layer 101, a flexible support layer 103 fixedly connected to the inner wall of the intermediate functional reinforcement layer 102, an anti-ultraviolet protective layer 104 fixedly connected to the inner wall of the flexible support layer 103, and an inner waterproof layer 105 fixedly connected to the inner wall of the anti-ultraviolet protective layer 104. This combination of different materials and layers enables the parachute fabric 1 to possess excellent tear resistance, abrasion resistance, flexibility, ultraviolet resistance, and waterproofness, ensuring that the parachute can still perform well under extreme weather conditions, improving safety and extending service life. This multi-layered structure design allows the parachute to exhibit higher reliability and durability when facing different environmental challenges.

[0023] Further as Figure 2 As shown, it is worth noting that the tear-resistant layer 101 is made of Kevlar material, which has extremely high tensile strength and tear resistance, effectively resisting strong winds and friction at high speeds, preventing the parachute fabric 1 from tearing or breaking during descent, and ensuring the safety of the parachute; the intermediate functional reinforcement layer 102 is made of high-strength polyethylene material, which has excellent strength and abrasion resistance, maintaining the structural integrity of the parachute fabric 1 under high tensile stress; the flexible support layer 103 is made of polyurethane material, which has good flexibility, effectively providing support without affecting the flexibility of the parachute fabric 1, helping the parachute fabric 1 maintain a stable shape, and ensuring smooth deployment of the parachute fabric at the moment of opening; the UV-resistant protective layer 104 is made of UV-protective coating, effectively preventing damage to the parachute fabric 1 from solar ultraviolet rays, avoiding aging, brittleness, or fading of the material caused by ultraviolet rays; the inner waterproof layer 105 is made of polytetrafluoroethylene film, which has excellent waterproof properties, preventing rainwater penetration and moisture from entering the parachute fabric 1, ensuring that the parachute fabric 1 maintains good working condition in humid environments.

[0024] Further as Figure 1 As shown, it is worth noting that multiple connecting rings 3 are evenly distributed symmetrically at the bottom of the anti-tipping net 2. The even distribution of connecting rings 3 can ensure that the load of the parachute rope 4 is evenly distributed in all directions, thereby reducing the risk of excessive pressure in some areas, preventing the parachute rope 4 from breaking or the parachute cloth 1 from deforming, enhancing the overall structural stability of the parachute, and ensuring that the parachute is more reliable and safer during use.

[0025] As can be seen from the above working process, by setting up a tear-resistant layer 101, an intermediate functional reinforcement layer 102, a flexible support layer 103, an anti-ultraviolet protective layer 104, and an inner waterproof layer 105 in combination, the parachute fabric 1 can have excellent tear resistance, abrasion resistance, flexibility, ultraviolet resistance, and waterproofness, ensuring that the parachute can still perform well under extreme weather conditions, improving safety and extending service life. This multi-layer structure design enables the parachute to exhibit higher reliability and durability when facing different environmental challenges.

[0026] Further as Figure 3 As shown, it is worth noting that the paracord 4 includes an outer sheath 401, a tensile filler 402 fixedly connected to the inner wall of the outer sheath 401, a plurality of first reinforcing ribs 403 fixedly connected to the inner wall of the tensile filler 402 near its edge, an elastic layer 404 fixedly connected to the center of the inner wall of the tensile filler 402, a fireproof layer 405 fixedly connected to the inner wall of the elastic layer 404, a load-bearing layer 406 fixedly connected to the inner wall of the fireproof layer 405, a plurality of second reinforcing ribs 407 fixedly connected to the inner wall of the load-bearing layer 406 near its edge, and a main rope core 407 fixedly connected to the center of the inner wall of the load-bearing layer 406. 8. By setting up a multi-layered composite structure for the parachute lines 4, using a variety of high-strength materials such as aramid, polyethylene, and stainless steel wire, the parachute lines 4 have extremely high tensile strength. Under conditions of rapid parachute descent and strong winds and impacts, the parachute lines 4 can withstand large tension, ensuring that the parachute canopy 1 unfolds stably and works normally. At the same time, the inner elastic layer can have a certain degree of extensibility and cushioning when bearing tension, helping to disperse sudden impact forces and preventing damage to the parachute lines 4 or deformation of the parachute canopy 1 due to excessive instantaneous tension when the parachute opens, thus ensuring smooth unfolding and stability during the descent.

[0027] Further as Figure 3 As shown, it is worth noting that the outer sheath 401 is made of polyester fiber, which provides good tear resistance; the tensile filler 402 is made of aramid fiber, which can increase the tensile strength of the rope while reducing weight; the first reinforcing rib 403 is made of stainless steel wire, which increases the structural stability and durability of the rope; the elastic layer 404 is made of polyurethane, which has good elasticity and compression resistance, and also provides a certain cushioning function; the fireproof layer 405 is made of flame-retardant polyester fiber, which has excellent fire resistance, and the flame-retardant polyester can also effectively prevent fire sources from damaging the rope; the load layer 406 is made of polyethylene, which can maintain a light weight while ensuring strength; the second reinforcing rib 407 is made of acrylic fiber, which has high tensile strength, abrasion resistance and appropriate rigidity; and the main rope core 408 is made of high-strength polyethylene, which can ensure the high strength and lightweight of the paracord 4.

[0028] Further as Figure 1 As shown, it is worth noting that the umbrella fabric 1, anti-tumble net 2, connecting ring 3, and umbrella rope 4 are all fixedly connected by high-strength stitching. High-strength stitching can evenly distribute the stress of each component throughout the connection, preventing damage to individual connection points due to excessive force. Especially under conditions of high wind speed or large impact force, it can effectively reduce the risk of local damage.

[0029] In summary: By combining a tear-resistant layer 101, an intermediate functional reinforcement layer 102, a flexible support layer 103, a UV-resistant protective layer 104, and an inner waterproof layer 105, the parachute fabric 1 possesses excellent tear resistance, abrasion resistance, flexibility, UV resistance, and waterproofness. This ensures the parachute maintains good performance under extreme weather conditions, improving safety and extending its service life. This multi-layered design allows the parachute to exhibit higher reliability and durability when facing various environmental challenges. The parachute ropes 4, with their multi-layered composite structure, utilize a variety of high-strength materials such as aramid, polyethylene, and stainless steel wire. This gives the parachute ropes 4 extremely high tensile strength. Under conditions of rapid parachute descent and strong winds or impacts, the parachute ropes 4 can withstand significant tension, ensuring the parachute canopy 1 unfolds stably and functions normally. At the same time, the inner elastic layer provides a certain degree of extensibility and cushioning when subjected to tension, helping to disperse sudden impact forces and preventing damage to the parachute ropes 4 or deformation of the parachute canopy 1 due to excessive instantaneous tension during parachute opening. This ensures smooth and stable unfolding during descent.
