Description

Technical Field

[0001] The utility model relates to the technical field of ropes, in particular to a double-layer braided rope with complex braiding. Background Technique

[0002] After retrieval, the Chinese patent publication number is CN207091800U, and the publication date is March 13, 2018. It discloses a safety cable, including a cable body formed by twisting a plurality of strands of ropes. A plurality of protective sleeves are arranged on the cable body. The protective sleeves are adhered to the cable body through an adhesive. The plurality of protective sleeves are arranged in sequence and spaced on the cable body. The distance between adjacent two protective sleeves is 1-2 meters. A rubber protective sleeve is arranged on the cable body. The damage of the rubber protective sleeve is obvious. The cable can be replaced in time by observing the damage of the rubber protective sleeve. At the same time, the rubber protective sleeve also enhances the strength of the cable, and the wear-resistant layer on the rubber protective sleeve enhances the wear resistance of the cable. However, when the device is in use, since the cable body is formed by twisting and winding multiple strands of ropes, there will be gaps between adjacent strands. Therefore, when people hold the cable and use it, they will feel uncomfortable. Content of the Utility Model

[0004] The purpose of the utility model can be realized by the following technical solutions:

[0005] A double-layer braided rope with complex braiding includes a central rope core. The outer surface of the central rope core is twisted with 6 strands of ropes, and adjacent strands are in contact with each other. There is a first protective sleeve with an S-twist direction on the outside of the strands. A first filler is arranged between the first protective sleeve and the strands. There is a second protective sleeve with an S-twist direction on the outside of the first protective sleeve. A wear-resistant layer is arranged on the outside of the second protective sleeve.

[0006] As a further scheme of the utility model: A second filler is arranged between the central rope core and the strands.

[0007] As a further scheme of the utility model: The twist directions of the first protective sleeve and the second protective sleeve are opposite.

[0008] As a further scheme of the utility model: The thicknesses of the first protective sleeve and the second protective sleeve are both 0.5mm - 1.5mm.

[0009] As a further scheme of the utility model: The central rope core is a polyester-propylene mixed rope, and the strands are ultra-high molecular weight polyethylene ropes.

[0010] As a further scheme of the utility model: The preparation materials of the first filler and the second filler are both flame-retardant modified polyarylate fibers.

[0011] The utility model provides a double - braided and double - layer woven rope. Compared with the prior art, it has the following beneficial effects:

[0012] (1) By using the filling material one to fill the gap between a pair of adjacent strands, the outer sides of the strands and the filling material one are on the same circumference. At the same time, the strands and the filling material one are double - wrapped and protected by the protective sleeve one and the protective sleeve two, making the whole rope cylindrical and improving the overall comfort of the rope.

[0013] (2) By setting the filling material two, the gap between the central rope core and the strands is filled, avoiding excessive deformation of the strands when the rope is stressed and squeezed, thereby indirectly improving the overall comfort of the rope. Description of the Drawings

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0018] Please refer to Figure 1-2 As shown, the present utility model is a double - braided and double - layer woven rope, including a central rope core 1. The outer surface of the central rope core 1 is wrapped with 6 strands 2, and adjacent strands 2 are in contact with each other. There is a protective sleeve one 3 with an S - twist direction on the outside of the strands 2. There is a filling material one 4 between the protective sleeve one 3 and the strands 2. There is a protective sleeve two 5 with an S - twist direction on the outside of the protective sleeve one 3. There is a wear - resistant layer 6 on the outside of the protective sleeve two 5. By using the filling material one 4 to fill the gap between adjacent strands 2, the outer sides of the strands 2 and the filling material one 4 are on the same circumference. At the same time, the strands 2 and the filling material one 4 are double - wrapped and protected by the protective sleeve one 3 and the protective sleeve two 5, making the whole rope cylindrical and improving the overall comfort of the rope.

[0019] A filler two 7 is provided between the central core 1 and the strands 2. By providing the filler two 7, the gap between the central core 1 and the strands 2 is filled, preventing the strands 2 from undergoing excessive deformation when the cable is subjected to compressive force, thereby indirectly improving the overall comfort of the cable.

[0020] The twisting directions of the first protective sleeve 3 and the second protective sleeve 5 are oppositely arranged.

[0021] The thicknesses of both the first protective sleeve 3 and the second protective sleeve 5 are 0.5 mm - 1.5 mm.

[0022] The central core 1 is a polyester - polypropylene mixed rope, and the strands 2 are ultra - high - molecular - weight polyethylene ropes.

[0023] The preparation materials of both the filler one 4 and the filler two 7 are flame - retardant modified polyarylate fibers.

[0024] Meanwhile, the content not described in detail in this specification belongs to the well - known prior art in the art.

[0025] The working principle of the present utility model: By using the filler one 4 to fill the gaps between adjacent strands 2, the outer sides of the strands 2 and the filler one 4 are on the same circumference. At the same time, the first protective sleeve 3 and the second protective sleeve 5 are used to double - wrap and protect the strands 2 and the filler one 4, making the overall cable cylindrical and improving the overall comfort of the cable. In addition, by providing the filler two 7, the gap between the central core 1 and the strands 2 is filled, preventing the strands 2 from undergoing excessive deformation when the cable is subjected to compressive force, thereby indirectly improving the overall comfort of the cable.
