[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] See also Figure 1-Figure 3The utility model provides a technical solution: a drag chain cable, comprising a cable drag chain 1, a first elastic filling layer 3, a second elastic filling layer 4 and a cable 8. A plurality of square elastic rubber frames 2 are arranged side by side from left to right inside the cable drag chain 1. A plurality of through holes 7 are penetrated through the upper and lower ends of the cable drag chain 1 and the upper and lower ends of the plurality of square elastic rubber frames 2. A plurality of first elastic filling layers 3 and a plurality of second elastic filling layers 4 are provided. The plurality of first elastic filling layers 3 and the plurality of second elastic filling layers 4 are respectively fixed at the upper and lower ends of the plurality of square elastic rubber frames 2. The connection between the plurality of first elastic filling layers 3 and the plurality of second elastic filling layers 4 is penetrated with an elliptical groove 5. A plurality of cables 8 are provided. The plurality of cables 8 are respectively inserted in the plurality of elliptical grooves 5. The plurality of cables 8 are provided with conductors 10. This design solves the problems of the original device.

[0018] As the first embodiment of the utility model: the upper and lower ends of the first elastic filling layer 3 and the second elastic filling layer 4 are equidistantly provided with multiple air holes 6, and the multiple through holes 7 are respectively connected to the multiple air holes 6. The opened through holes 7 and air holes 6 can quickly discharge the internal gas when the first elastic filling layer 3 and the second elastic filling layer 4 are squeezed and deformed by the cable 8, thereby making it more convenient to compress the first elastic filling layer 3 and the second elastic filling layer 4.

[0019] The cross-sections of the multiple cables 8 are all elliptical, and they are completely fitted with the multiple elliptical grooves 5 respectively. The multiple cables 8 are set to be elliptical so that they can be completely fitted with the multiple elliptical grooves 5 respectively, and the left and right widths of the cross-sections of the cables 8 are greater than the up and down heights, which can reduce the bending force when the cables are bent in the up and down directions. At the same time, the elliptical cables 8 will not twist easily. A protective layer 9 is filled between the multiple cables 8 and the conductor 10, and the multiple protective layers 9 are all made of a mixture of PVC.

[0020] As a second embodiment of the present utility model: when the cable drag chain 1 is bent (refer to Figure 1 ), the elliptical cable 8 is bent synchronously, and then bent in the up and down directions, thereby squeezing the first elastic filling layer 3 and the second elastic filling layer 4, and the first elastic filling layer 3 and the second elastic filling layer 4 will be squeezed and deformed accordingly according to the bending condition of the cable 8, and the first elastic filling layer 3 and the second elastic filling layer 4 can protect the cable 8, and also prevent the internal conductor 10 of the cable 8 from being tightened and broken. At the same time, the through holes 7 and the air holes 6 opened can quickly discharge the internal gas of the first elastic filling layer 3 and the second elastic filling layer 4 when they are squeezed and deformed by the cable 8, thereby making it more convenient to compress the first elastic filling layer 3 and the second elastic filling layer 4, and setting multiple cables 8 in an elliptical shape can fully fit with multiple elliptical grooves 5 respectively, and the left and right width of the cross-section of the cable 8 is greater than the up and down height, which can reduce the bending force when it is bent in the up and down directions, and the elliptical cable 8 will not twist easily.
