[0009] In some embodiments, the inner wall of the cable hole is formed with internal threads.

[0010] In some embodiments, the length of the outer metal wire layer of the anchoring section is 0.5-1 times the diameter of the main body section of the cable, and the length of the inner metal wire layer of the anchoring section is 3-5 times the diameter of the main body section of the cable.

[0011] In some embodiments, the center of the cable is coaxial with the center of the anchor.

[0012] In some embodiments, the inner metal wire layer comprises multiple alloy steel wires or stainless steel wires; the outer metal wire layer comprises multiple stainless steel wires, copper wires, or aluminum wires.

[0013] In some embodiments, the cable body is a steel strand cable body, a steel wire rope body, or a sealed cable body; the filler is a hot-cast alloy or a cold-cast material.

This makes the gripping force of the outer metal wire layer relatively less than that of the inner metal wire layer after anchoring. When the cable is under overall stress, the outer metal wire layer does not loosen. When under axial stress, the outer metal wire layer is subjected to less axial tension, thereby reducing the probability of the outer metal wire layer breaking or undergoing excessive tensile deformation. This ensures the decorative, durable and stable properties of the outer metal wire layer, and thus expands the application scenarios and scope of the cable. Attached Figure Description

[0035] In related technologies, to improve the aesthetics of cables, wire-like metal products are wrapped around the outside of the cables. In most cases, the steel wires of the cables are made of different materials from the external wire-like metal products. Common examples include alloy steel cables wrapped with stainless steel wire, copper wire, or aluminum wire, or stainless steel cables wrapped with copper wire or aluminum wire, etc.

[0036] However, due to the different materials of the steel wires in the cable and the outer wire-like metal product, there are significant differences in tensile strength and elongation. As a result, when the cable is under stress, the outer wire-like metal product is prone to breakage and excessive stretching deformation, which affects the decorative, durable and stable properties of the outer wire-like metal product, and thus limits the application scenarios and scope of the cable.

[0037] Based on the above problems, this application proposes a cable and its manufacturing method, which can ensure the decorativeness, durability and stability of the outer metal wire layer of the cable, thereby expanding the application scenarios and scope of the cable.

[0038] Reference Figure 1 , Figure 1 A schematic diagram of the cable structure in some embodiments of this application is shown. The cable includes a cable body 10 and an anchor 20; the cable body 10 includes an inner wire layer 110 and an outer wire layer 120, and is divided into a main body section 10a and an anchoring section 10b, wherein the outer wire layer 120 of the anchoring section 10b is shorter than the inner wire layer 110; the first end 20a of the anchor 20 forms a through hole 210, and the second end 20b of the anchor 20 forms a connecting hole 220, wherein the through hole 210 communicates with the connecting hole 220; the main body section 10a of the cable body 10 is located outside the anchor 20, and the anchoring section 10b of the cable body 10 is located inside the connecting hole 220; the space between the anchoring section 10b and the connecting hole 220 is filled with filler 30, which is used to fix the anchoring section 10b inside the connecting hole 220.

[0039] The cable provided in this application includes a cable body 10 and an anchor 20. The cable body 10 includes an inner wire layer 110 and an outer wire layer 120. The cable body 10 is divided into a main body section 10a and an anchoring section 10b. The outer wire layer 120 of the anchoring section 10b is shorter than the inner wire layer 110. The first end 20a of the anchor 20 forms a cable passage hole 210, and the second end 20b of the anchor 20 forms a connecting hole 220. The cable passage hole 210 communicates with the connecting hole 220. The main body section 10a of the cable body 10 is located outside the anchor 20, and the anchoring section 10b of the cable body 10 is located inside the connecting hole 220. The space between the anchoring section 10b and the connecting hole 220 is filled with filler 30, which is used to fix the anchoring section 10b inside the connecting hole 220. The cable of this application has an outer metal wire layer 120 shorter than the inner metal wire layer 110 in the anchoring section 10b, and filler 30 is filled in the space between the anchoring section 10b and the connecting hole 220. This makes the holding force of the outer metal wire layer 120 less than that of the inner metal wire layer 110 after anchoring. When the cable is under overall stress, the outer metal wire layer 120 does not loosen. When under axial stress, the outer metal wire layer 120 is subjected to less axial tension, thereby reducing the probability of the outer metal wire layer 120 breaking or undergoing excessive tensile deformation, ensuring the decorative, durable and stable properties of the outer metal wire layer 120, and thus expanding the application scenarios and scope of the cable.

[0040] In some embodiments, the diameter of the connecting hole 220 gradually decreases along the direction from the first end 20a of the anchor 20 to the second end 20b of the anchor 20, and both the inner wire layer 110 and the outer wire layer 120 of the anchoring section 10b are broom-shaped. This facilitates the installation of the anchoring section 10b of the cable 10 within the connecting hole 220. The broom-shaped arrangement of the inner wire layer 110 and the outer wire layer 120 of the anchoring section 10b increases the uniformity of the spatial distribution of the filler 30 within the inner and outer wire layers 120 and between the inner and outer wire layers 120 and the connecting hole 220, thereby improving the load-bearing capacity of the anchoring section 10b of the cable and enhancing the firmness and stability of the connection between the anchoring section 10b of the cable and the anchor 20.

[0041] In some embodiments, the connecting hole 220 includes a first circular hole segment 221, a conical hole segment 222, and a second circular hole segment 223 connected in sequence. The first circular hole segment 221 communicates with the cable passage hole 210. The diameter of the first circular hole segment 221 is equal to the maximum diameter of the conical hole segment 222, and the diameter of the second circular hole segment 223 is equal to the minimum diameter of the conical hole segment 222. The anchoring segment 10b is located in the conical hole segment 222, and the filler 30 fills the space between the anchoring segment 10b and the conical hole segment 222. This ensures that the axial length of the connecting hole 220 is greater than the length of the anchoring segment 10b, thereby ensuring that the anchoring segment 10b of the cable is located within the connecting hole 220. The filler 30 effectively fills the space between the anchoring segment 10b of the cable and the connecting hole 220, thereby improving the connection stability between the anchoring segment 10b of the cable and the connecting hole 220.

[0042] In some embodiments, a collar 40 is provided within the second circular hole section 223, and the collar 40 is fitted at the connection between the anchoring section 10b and the main body section 10a. The collar 40 allows the inner wire layer 110 and the outer wire layer 120 of the anchoring section 10b of the cable to spread out in a broom-like shape while maintaining the structural stability of the main body section 10a of the cable.

[0043] In some embodiments, both the cable through hole 210 and the connecting hole 220 extend along the axial direction of the anchor 20, thereby facilitating the insertion of the cable into the anchor 20.

[0044] In some embodiments, the inner wall of the cable hole 210 is formed with an internal thread 211, which facilitates the connection of the anchor 20 with other connecting components, such as the connection of the anchor 20 with the connecting screw, thereby facilitating the fixing of the cable to the building structure.

[0045] In some embodiments, the length L1 of the outer wire layer 120 of the anchoring section 10b is 0.5-1 times the diameter of the main body section 10a of the cable body 10, and the length L2 of the inner wire layer 110 of the anchoring section 10b is 3-5 times the diameter of the main body section 10a of the cable body 10. Thus, when the filler 30 fixes the anchoring section 10b within the connecting hole 220 of the anchor 20, the gripping force of the outer wire layer 120 is less than that of the inner wire layer 110. When the cable is under overall stress, the outer wire layer 120 does not loosen, and when under axial stress, the outer wire layer 120 experiences less axial tension. This significantly reduces the probability of the outer wire layer 120 breaking or undergoing excessive tensile deformation, ensuring the decorative, durable, and stable properties of the outer wire layer 120, thereby expanding the application scenarios and scope of the cable.

[0046] In some embodiments, the center of the cable body 10 is coaxially arranged with the center of the anchor 20, thereby ensuring that the inner wire layer 110 and the outer wire layer 120 of the cable are subjected to uniform force, which can effectively improve the service life of the cable.

[0047] In some embodiments, the inner metal wire layer 110 includes multiple alloy steel wires, and the outer metal wire layer 120 includes multiple stainless steel wires, copper wires, or aluminum wires; or, the inner metal wire layer 110 includes multiple stainless steel wires, and the outer metal wire layer 120 includes multiple copper wires or aluminum wires.

[0048] In some embodiments, the cable body 10 is a steel strand cable body 10, a steel wire rope body 10, or a sealed cable body 10.

[0049] In some embodiments, the cable can be fixed to the anchor 20 by hot casting or cold casting anchoring. Therefore, the filler 30 can be a hot-cast alloy or a cold-cast material.

[0050] Reference Figure 2 and Figure 3 , Figure 2 A flowchart illustrating the manufacturing process of a cable in some embodiments of this application is shown; Figure 3 A flowchart illustrating a method for manufacturing a cable according to some embodiments of this application is shown. The method includes:

[0051] S1. Fabrication: The inner metal wire layer 110 and the outer metal wire layer 120 are twisted according to certain rules to obtain a cable body 10 including the inner metal wire layer 110 and the outer metal wire layer 120.

[0052] Specifically, depending on the engineering requirements and the desired wrapping effect of the outer metal wire layer 120, the inner metal wire layer 110 and the outer metal wire layer 120 can be twisted according to certain rules to obtain the cable body 10 with the desired structure.

[0053] S2. Insert one end of the cable body 10 obtained by the process through the connecting hole 220 and the cable hole 210 of the anchor 20, and extend it out from the first end 20a of the anchor 20.

[0054] Specifically, one end of the fabricated cable 10 is passed sequentially through the connecting hole 220 and the cable hole 210 of the anchor 20, and extends out from the first end 20a of the anchor 20. It is necessary to ensure that the length of the cable 10 extending out of the first end 20a of the anchor 20 is greater than the length of the connecting hole 220 of the anchor 20, so as to ensure that the subsequent cable 10 is located within the length of the connecting hole 220, thereby improving the firmness of the cable 10 fixed in the anchor 20. It can be understood that the length of the connecting hole 220 of the anchor 20 can refer to the length of the connecting hole 220 along the axial direction of the anchor 20.

[0055] S3. Cutting: Cut the outer metal wire layer 120 of the cable body 10 extending from the first end 20a of the anchor 20 to divide the cable body 10 into the anchoring section 10b and the main body section 10a.

[0056] S4. Reset: Reset the cut cable body 10 so that the main body section 10a of the cable body 10 is located outside the anchor 20, and the anchoring section 10b of the cable body 10 is located inside the connecting hole 220 of the anchor 20.

[0057] Specifically, by pulling the cable body 10, the anchoring section 10b of the cable body 10 can be inserted into the connecting hole 220 of the anchor 20, while the main body section 10a of the cable body 10 is located outside the anchor 20.

[0058] S5. Filling: Fill the space between the anchoring section 10b of the cable body 10 and the connecting hole 220 with filler 30 so that the anchoring section 10b of the cable body 10 is fixed in the connecting hole 220.

[0059] Specifically, the anchoring section 10b of the cable body 10 can be fixed in the connecting hole 220 by hot casting or cold casting. Therefore, hot casting alloy or cold casting material can be poured into the space between the anchoring section 10b of the cable body 10 and the connecting hole 220 so that the anchoring section 10b of the cable body 10 is fixed in the connecting hole 220.

[0060] The cable manufacturing method of this application involves cutting the outer metal wire layer 120 of the cable body 10 extending from the first end 20a of the anchor 20 to divide the cable body 10 into an anchoring section 10b and a main body section 10a. The outer metal wire layer 120 of the anchoring section 10b is shorter than the inner metal wire layer 110. The anchoring section 10b of the cable body 10 is located in the connecting hole 220 of the anchor 20. The space between the anchoring section 10b of the cable body 10 and the connecting hole 220 is filled with filler 30 so that the anchoring section 10b of the cable body 10 is fixed in the connecting hole 220. Since the outer metal wire layer 120 of the anchoring section 10b is shorter than the inner metal wire layer 110, after the filler 30 fixes the anchoring section 10b of the cable body 10 into the connection hole 220 of the anchor 20, the gripping force of the outer metal wire layer 120 after anchoring is less than that of the inner metal wire layer 110. When the cable is under overall stress, the outer metal wire layer 120 does not loosen. When under axial stress, the outer metal wire layer 120 is subjected to less axial tension, thereby reducing the probability of the outer metal wire layer 120 breaking or undergoing excessive tensile deformation, ensuring the decorative, durable and stable properties of the outer metal wire layer 120, and thus expanding the application scenarios and scope of the cable.

[0061] Combination Figure 4 , Figure 4 Another flowchart illustrating a method for manufacturing a cable according to some embodiments of this application is shown. In this embodiment, after step S3, the manufacturing method further includes:

[0062] S3A, bend the wires: bend the wires of the anchoring section 10b of the cable body 10 so that the inner metal wire layer 110 and the outer metal wire layer 120 of the anchoring section 10b are broom-shaped.

[0063] S3B, Clean and dry the inner wire layer 110 and outer wire layer 120 of the anchoring section 10b and the connection hole 220 of the anchor 20.

[0064] In some embodiments, after step S4, the manufacturing method further includes:

[0065] S4A, Positioning: The center of the cable body 10 is coaxially aligned with the center of the anchor 20. This ensures that the inner wire layer 110 and the outer wire layer 120 of the cable are subjected to uniform stress, effectively improving the service life of the cable.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
