The cable bodies are located in the drag chain assembly, which can prevent the cable bodies from being entangled or worn with each other, and are very practical.

[0030] However, during the process of assembling the drag chain cable, it was found that the existing drag chain cable requires the cable body to pass through the drag chain assembly as a whole, which makes assembly troublesome, time-consuming and labor-intensive, and the cable body is easily damaged when dragging. In addition, after assembly, the cable body is prone to move axially relative to the drag chain assembly, resulting in poor assembly stability.

[0031] Therefore, the utility model provides a tow chain cable, which can effectively solve the above problems.

[0032] Reference below Figures 1 to 3 A drag chain cable according to an embodiment of the utility model is described.

[0033] refer to Figures 1 to 3 As shown, the drag chain cable according to the embodiment of the present utility model includes a drag chain assembly 100 and a plurality of cable bodies 200 .

[0034] For example, the drag chain assembly 100 includes a plurality of drag chain units 101, and two adjacent drag chain units 101 are hinged to each other. Specifically, one of the ends of the two adjacent drag chain units 101 that are close to each other may be provided with a connection hole, and the other may be provided with a connection column, and the connection column is rotatably installed in the connection hole. Of course, the two adjacent drag chain units 101 may also be hinged by hinges. The drag chain unit 101 includes a base 102 and a cover plate 103. The base 102 is provided with a plurality of placement grooves 104. The plurality of placement grooves 104 may be arranged along the width direction of the drag chain assembly 100. The placement grooves 104 may penetrate along the length direction of the drag chain assembly 100. The placement grooves 104 are provided with a take-in and put-out opening 105. The cover plate 103 is provided on the base 102 to cover or open the take-in and put-out opening 105. Specifically, the cover plate 103 may be movably and adjustably installed on the base 102 or detachably installed on the base 102. When the cover plate 103 When the cover 103 is movably and adjustably installed on the base 102, the cover 103 can cover or open the access opening 105 during the process of movable adjustment. When the cover 103 is detachably installed on the base 102, the access opening 105 can be covered by installing the cover 103, and the access opening 105 can be opened by removing the cover 103. The cover 103 is provided with a plurality of abutment portions 106 corresponding to the mounting grooves 104. Specifically, the plurality of abutment portions 106 of the cover 103 of the same drag chain unit 101 correspond one-to-one to the plurality of mounting grooves 104 of the base 102.

[0035] The plurality of cable bodies 200 are respectively placed in the plurality of placement grooves 104. Specifically, when installing the cable body 200, the cover plate 103 is operated to open the access opening 105, and then the plurality of cable bodies 200 are respectively placed in the plurality of placement grooves 104.

[0036] When the cover plate 103 covers the access opening 105 , the abutment portion 106 is just located above the mounting groove 104 , and the bottom end of the abutment portion 106 can be inserted into the access opening 105 at the top of the mounting groove 108 , so that the abutment portion 106 can abut against the side of the cable body 200 close to the cover plate 103 .

[0037] In the utility model, when assembling, the cover plate 103 can be opened to open the access opening 105 of the placement groove 104, and then the multiple cable bodies 200 can be respectively placed in the multiple placement grooves 104, and then the cover plate 103 is covered. The cover plate 103 covers the access opening 105, which is convenient for assembly, saves time and effort, and there is no need to drag the cable body 200 when assembling the drag chain cable, so it is not easy to damage the cable body 200. In addition, after assembly, the abutment portion 106 on the cover plate 103 can abut the side of the cable body 200 close to the cover plate 103. Through the tightening action of the abutment portion 106, the cable body 200 can be tightened to prevent the cable body 200 from moving axially relative to the drag chain assembly 100, and the assembly stability is better.

[0038] In some embodiments of the present invention, Figure 2 As shown, an end of the abutting portion 106 away from the cover plate 103 is formed with an abutting surface 107, which is set as a concave arc surface and matches the outer wall of the cable body 200. In this way, when the cover plate 103 covers the access opening 105, the abutting surface 107 can just fit tightly against the outer wall of the cable body 200, thereby achieving a better abutting effect on the cable body 200, thereby achieving a better fastening effect on the cable body 200.

[0039] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the base 102 is provided with a mounting groove 108, the mounting groove 108 penetrates along the length direction of the drag chain assembly 100, a plurality of placement portions 109 arranged along the width direction of the drag chain assembly 100 are provided in the mounting groove 108, and the placement groove 104 is provided in the placement portion 109. In this embodiment, a plurality of placement grooves 104 are provided in the mounting groove 108 of the base 102 through a plurality of placement portions 109, so that the cable body 200 is more convenient to place, and the cable body 200 is arranged more neatly, which can further prevent the cable body 200 from being entangled.

[0040] In some embodiments of the present invention, Figure 2 As shown, the placement portion 109 is formed with clamping walls 110 on both sides of the placement groove 104, and the cover plate 103 is provided with a plurality of extrusion portions 111. When the cover plate 103 covers the access opening 105, two adjacent extrusion portions 111 squeeze the opposite sides of the two clamping walls 110 of the same placement portion 109, so that the two clamping walls 110 of the same placement portion 109 are bent and deformed in opposite directions to clamp the cable body 200. In this embodiment, when the cover plate 103 covers the access port 105, the two adjacent extrusion portions 111 are located outside the opposite side of the two clamping walls 110 of the same placement portion 109 and squeeze the two clamping walls 110 of the same placement portion 109 inward. The two clamping walls 110 of the same placement portion 109 are subjected to the opposite extrusion forces and can bend and deform in opposite directions, thereby clamping the cable body 200, so that the cable body 200 can be further tightened, further preventing the cable body 200 from moving axially relative to the drag chain assembly 100, and also preventing the cable body 200 from moving left and right, and the assembly stability of the cable body 200 is better.

[0041] In some embodiments of the present invention, Figure 2As shown, the extrusion portion 111 forms extrusion surfaces 112 on two side surfaces in the width direction of the drag chain assembly 100, and the two extrusion surfaces 112 of the same extrusion portion 111 are close to each other in the direction away from the cover plate 103. Specifically, the extrusion portion 111 can be V-shaped or conical, and the tip of the extrusion portion 111 is located at the end of the extrusion portion 111 away from the cover plate 103. The two extrusion surfaces 112 of the extrusion portion 111 are arranged along the width direction of the drag chain assembly 100, and the two extrusion surfaces 112 of the same extrusion portion 111 are close to each other in the direction away from the cover plate 103. With such a configuration, when the cover plate 103 covers the access opening 105, it is more convenient for the extrusion portion 111 to squeeze the corresponding clamping wall 110, avoiding interference between the extrusion portion 111 and the clamping wall 110.

[0042] In some embodiments of the present invention, Figure 2 As shown, when the cover plate 103 covers the access opening 105, the clamping walls 110 on the side where two adjacent placement parts 109 are close to each other are squeezed by the same squeezing part 111. Specifically, the distance between the clamping walls 110 on the side where two adjacent placement parts 109 are close to each other is relatively short. When the cover plate 103 covers the access opening 105, the squeezing part 111 located in the middle is inserted between the clamping walls 110 on the side where two adjacent placement parts 109 are close to each other, so that the two clamping walls 110 can be squeezed at the same time. The operation is simple and convenient, and there is no need to set two squeezing parts 111, so the structure is simpler.

[0043] In some embodiments of the present invention, the placement portion 109 is made of elastic material, for example, elastic rubber or elastic plastic, so that when the extrusion portion 111 extrudes the clamping wall 110, the bending deformation effect of the clamping wall 110 is better, thereby better clamping the cable body 200, and when the cover plate 103 is opened to separate the extrusion portion 111 from the clamping wall 110, the clamping wall 110 can return to a natural state, thereby facilitating the removal of the cable body 200.

[0044] In some embodiments of the present invention, Figure 2 As shown, a first ventilation channel 113 is formed between two adjacent placement portions 109, and a second ventilation channel 114 is formed between the side wall of the mounting groove 108 and the placement portion 109 adjacent thereto. In this embodiment, the first ventilation channel 113 and the second ventilation channel 114 are provided to achieve better ventilation effect of the drag chain cable, thereby achieving better heat dissipation effect, thereby preventing the drag chain cable from being damaged due to excessive temperature.

[0045] In some embodiments of the present invention, Figure 1 and Figure 2As shown, one end of the cover plate 103 is hinged to the base 102, and the other end of the cover plate 103 is connected to the base 102 through a fastener 115. Specifically, the base 102 is provided with a first connection hole, and the cover plate 103 is correspondingly provided with a second connection hole. When the cover plate 103 needs to be closed, the cover plate 103 is rotated to align the first connection hole with the second connection hole, and finally the fastener 115 is inserted, which is convenient to operate, and the connection of the cover plate 103 is more stable and the sealing effect is better. When the cover plate 103 needs to be opened, the fastener 115 is unscrewed, and then the cover plate 103 is rotated, which is also convenient to operate.

[0046] It should be noted that the cover plate 103 may also be connected to the base 102 in other ways. For example, both ends of the cover plate 103 may be connected to the base 102 via fasteners 115 .

[0047] In some embodiments of the present invention, Figure 3 As shown, the cable body 200 includes a protective sleeve 201, a tensile wire 202 and a plurality of core wires 203. The tensile wire 202 is arranged in the protective sleeve 201, and the plurality of core wires 203 are arranged in the protective sleeve 201 and arranged along the circumference of the tensile wire 202. The tensile wire 202 can be located at the center of the protective sleeve 201, and the tensile wire 202 can be made of Kevlar fiber. The outer side of the tensile wire 202 can be coated with a PVC sheath layer. The core wire 203 can be a conductive core wire or a communication core wire, and the protective sleeve 201 can be a rubber sleeve or a PVC sleeve. In this embodiment, the tensile wire 202 is arranged in the center of the cable body 200, so that the cable body 200 has a higher structural strength, a better tensile effect, and a longer service life.

[0048] It should be noted that the cable body 200 may also be other suitable structures, which will not be described in detail here.
