[0036] like Figure 1-5 As shown, an armored flat wire cable core in this embodiment includes a center rope 1, the outer layer of which is wound with a flat steel belt 2. The flat steel belt 2 is used to improve fatigue life and load efficiency. The center rope 1 includes an inner core layer 11, an intermediate layer 12, and an outer layer 13 distributed from the inside to the outside.

[0037] Grease is provided in the gaps between the inner core layer 11, the middle layer 12 and the outer layer 13 to enhance the lubrication effect;

[0038] The inner core layer 11 is formed by twisting a plurality of first steel wire ropes 111;

[0039] The intermediate layer 12 is formed by twisting a plurality of intermediate strands 121, and the intermediate strands 121 are formed by twisting a plurality of second steel wire ropes 1211;

[0040] The outer layer 13 is formed by twisting a plurality of first outer rope strands 131 and a plurality of second outer rope strands 132, and the plurality of first outer rope strands 131 and the plurality of second outer rope strands 132 are arranged alternately;

[0041] The first outer strand 131 is formed by twisting a plurality of third steel wire ropes 1311;

[0042] The second outer strand 132 is formed by twisting a plurality of fourth steel wire ropes 1321;

[0043] The diameter of the first steel rope 111 is equal to the diameter of the second steel rope 1211 , the diameter of the third steel rope 1311 is smaller than the diameter of the first steel rope 111 , and the diameter of the fourth steel rope 1321 is larger than the diameter of the first steel rope 111 ;

[0044] The specific number of the first steel ropes 111 is 7, the specific number of the second steel ropes 1211 in the single middle rope strand 121 is 7, the number of the third steel ropes 1311 in the single first outer rope strand 131 is 7, and the number of the fourth steel ropes 1321 in the single second outer rope strand 132 is 7;

[0045] The inner core layer 11, the middle strands 121, the first outer strands 131 and the second outer strands 132 all have a 6*7-WSC structure. For example, the number of first steel wire ropes 111 in the inner core layer 11 is 7, one of which serves as the rope core, and the remaining six are twisted into the outer layer of the rope core. That is, 7 represents the total number of first steel wire ropes 111 in the inner core layer 11, and 6 represents the number of first steel wire ropes 111 twisted into the outer layer of the rope core. This structure can enhance strength and stability while maintaining a certain degree of flexibility.

[0046] The specific number of the intermediate rope strands 121 is 6, the specific number of the first outer rope strands 131 is 6, and the specific number of the second outer rope strands 132 is 6;

[0047] Here, the center rope 1 adopts a combination of thick and thin steel wire ropes, which can store more grease, thereby improving the lubrication effect, greatly reducing friction, and thus improving fatigue performance and flexibility;

[0048] The outer layer of the flat steel strip 2 is polished to a smooth surface, such as a mirror surface, and the edges of the flat steel strip 2 are provided with rounded corners. In this way, the outer surface of the armored flat wire core is smoother, which improves the load efficiency of the product and also reduces the damage to the inner wall of the supporting product by the edge of the flat steel strip 2 after the product is assembled and bent.

[0049] In addition to the above embodiments, the present invention also includes other implementation methods. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of protection of the claims of the present invention.
