Description

Technical Field

[0001] The utility model relates to the technical field of cables, and in particular to a dust-free drag chain cable. Background Art

[0002] In some equipment that needs to move back and forth, in order to prevent the cables from getting tangled, worn, or scattered, the cables are often placed in a drag chain to form a drag chain cable. At present, drag chain cables have been widely used in industrial electronic systems, automatic production lines, storage equipment, robots, fire protection systems, cranes, CNC lathes, and metallurgical industries.

[0003] Existing drag chain cables usually include a protective sleeve, a cable clip, a keel layer and a cable, wherein the keel layer is used to support the cable clip, the cable is passed through the cable clip, and the protective sleeve is wrapped around the outside of the cable clip to protect the cable on the cable clip. However, in the prior art, when multiple layers of drag chain cables are stacked, the protective sleeve is not designed properly, which can easily cause wear to the cables in adjacent layers. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the purpose of the present invention is to provide a dust-free drag chain cable, which can effectively reduce the risk of cable wear caused by stacking.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: a dust-free drag chain cable, comprising

[0006] At least one line card is stacked inside and outside, each of the line cards is provided with at least one cable slot for accommodating a cable, and the cable slot runs through the length direction of the line card;

[0007] A protective cover is provided corresponding to each of the line cards and can be covered on the corresponding line card; and a side of the protective cover away from the corresponding line card is a plane, and a side of the protective cover facing the corresponding line card is provided with an opening and closing member for opening or closing the protective cover, and the opening and closing member can move along the length direction of the corresponding line card;

[0008] The line card is provided with a limiting groove for accommodating the movement of the opening and closing member, and the limiting groove is located between any two adjacent cable grooves.

[0009] The beneficial effects of the dust-free drag chain cable of the utility model are:

[0010] First, by providing protective covers corresponding to the line cards one by one, it is ensured that the cables on each layer of line cards can be independently protected by the protective covers, and then the opening or closing of the protective covers is realized by the setting of the opening and closing parts, so as to facilitate the rapid assembly of the protective covers and the line cards; secondly, the side of the protective covers away from the line cards is provided as a plane, so that when two adjacent line cards are stacked, the protective covers are facing the adjacent line cards with the plane; and the opening and closing parts are provided on the side of the protective covers facing the corresponding line cards, so that the movement of the opening and closing parts can be built in between the protective covers and the corresponding line cards, which is equivalent to a hidden opening and closing structure, thereby avoiding the scratching and wear of the adjacent layer of line cards during the opening and closing process of the opening and closing parts; finally, by providing a limit groove on the line card, and limiting the limit groove between two adjacent cable grooves, since the cable groove and the limit groove are both provided along the length direction of the line card, therefore, during the movement of the opening and closing parts along the limit groove, the opening and closing parts will not touch the cables in the cable groove, thereby avoiding the scratching and wear of the cables on the corresponding line cards during the opening and closing process of the opening and closing parts.

[0011] Furthermore, the opening and closing member is an invisible zipper. The protective cover is opened and closed by the invisible zipper, which not only ensures the simplicity of the opening and closing action, but also ensures that the flat side of the protective cover will not be scratched due to the exposed zipper rack.

[0012] Furthermore, the two ends of the line card are provided with fixing clamps, and the size of the fixing clamps along the stacking direction is larger than the size of the line card along the stacking direction. When two line cards are stacked, a certain hollow distance must be left between the two line cards because the size of the fixing clamps along the stacking direction is larger. This arrangement can effectively avoid contact friction between the cables on the two adjacent line cards, and to a certain extent, it can protect the cables.

[0013] Furthermore, the fixing clamp includes an upper clamp and a lower clamp, and the upper clamp and the lower clamp are fixed by bolts and can be clamped on the line card. The end of the line card can be fixed by the arrangement of the upper clamp and the lower clamp.

[0014] Furthermore, along the stacking direction, a distance is left between two adjacent line cards to prevent the cables on the two adjacent line cards from being squeezed and worn.

[0015] Furthermore, the cross section of the line card along the stacking direction is in the shape of an elliptical racetrack, so that at least part of the line card is a plane. The cross section of the line card is set to be in the shape of an elliptical racetrack, so that multiple line cards can be stacked and placed at will, and the plane can increase the force area when the line card contacts other equipment, thereby reducing the damage to the surface of the drag chain cable by the ground or the workbench, and extending the service life of the drag chain cable.

[0016] Furthermore, along the stacking direction, the inner side of the line card located in the innermost layer is provided with a keel layer adapted to the shape of the line card, and a distance is left between the keel layer and the line card in the innermost layer. Since the line cards are mostly supported by flexible materials, by providing the keel layer at the innermost side in the stacking direction, it does not affect any stacking of the multiple line cards, and can also enhance the support for the stacked multiple line cards.

[0017] Furthermore, the cable troughs are arranged on the line card in a flat or stacked manner, and when the cable troughs are stacked, the cable troughs on different layers are staggered to minimize mutual interference between cables. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0029] Example

[0030] See attached Figure 1-5As shown, a dust-free drag chain cable of the utility model comprises at least one line card 1 stacked inside and outside, and a protective cover 2 corresponding to the line card 1. Each line card 1 is provided with at least one cable groove 11 for accommodating cables, and the cable groove 11 runs through the length direction of the line card 1. The protective cover 2 can be covered on the corresponding line card 1. And the side of the protective cover 2 away from the corresponding line card 1 (that is, the outside along the stacking direction) is a plane, and the side of the protective cover 2 facing the corresponding line card 1 is provided with an opening and closing member 21 for opening or closing the protective cover, and the opening and closing member 21 can move along the length direction of the corresponding line card 1.

[0031] First, by setting the protective cover 2 in one-to-one correspondence with the line card 1, it is ensured that the cables on each layer of the line card 1 can be independently protected by the protective cover 2, and then the opening and closing part 21 is set to realize the opening or closing of the protective cover 2, so as to facilitate the rapid assembly of the protective cover 2 and the line card 1; secondly, the side of the protective cover 2 away from the line card 1 is set as a plane, so that when two adjacent line cards 1 are stacked, the protective cover 2 is facing the adjacent line card 1 with the plane; and the opening and closing part 21 is set on the side of the protective cover 2 facing the corresponding line card 1, so that the movement of the opening and closing part 21 can be built in between the protective cover 2 and the corresponding line card 1, which is equivalent to a hidden opening and closing structure, thereby avoiding the scratches and wear of the adjacent layer of line cards 1 by the opening and closing process of the opening and closing part 21.

[0032] It should be noted that the cable slots 11 are arranged on the line card 1 in a flat or stacked manner, and when the cable slots 11 are stacked, the cable slots 11 on different layers are staggered to minimize mutual interference between cables. In addition, in actual application, the stacking setting of the line card 1 is determined according to the cable requirements. Figure 1 As shown, only one line card 1 is set. At this time, there is no cascading setting for the line card; when the cable on a single line card 1 cannot meet the usage requirements, such as Figure 5 As shown, the number of line cards 1 can be increased by stacking, thereby increasing the number and types of cables.

[0033] For further information, see Appendix Figure 2-3 As shown, the line card 1 is provided with a limit groove 12 for accommodating the movement of the opening and closing member 21, and the limit groove 12 is located between any two adjacent cable grooves 11. Since the opening and closing member 21 moves along the length direction of the line card 1, the limit groove 12 must be provided along the length direction of the line card 1, and the cable groove 11 is also arranged along the length direction of the line card 1. Therefore, by limiting the position of the limit groove 12 to between the two cable grooves 11, the limit groove 12 and the cable groove 11 can be parallel and non-interfering. When the opening and closing member 21 moves along the limit groove 12, the opening and closing member 21 will not touch the cable in the cable groove 11, thereby avoiding the scratching and abrasion of the cable on the corresponding line card 1 during the opening and closing process of the opening and closing member 21, thereby protecting the cable.

[0034] In some embodiments, see Appendix Figure 3-4 As shown, the opening and closing member 21 is an invisible zipper. The use of the invisible zipper to open and close the protective cover 2 not only ensures the simplicity of the opening and closing action, but also ensures that the side of the protective cover 2 that is a plane will not scratch the adjacent layer of the wire clip 1 (and the protective cover 2) due to the exposed zipper rack.

[0035] In order to avoid extrusion when the line cards 1 are stacked, in some embodiments, a spacing is left between two adjacent line cards 1 along the stacking direction so that the cables on the two line cards 1 will not be squeezed and worn.

[0036] For details, see the attached Figure 1 As shown, both ends of the line card 1 are provided with fixing clamps 3, and the size of the fixing clamps 3 along the stacking direction is larger than the size of the line card 1 along the stacking direction. When two line cards 1 are stacked, since the size of the fixing clamps 3 along the stacking direction is larger, a certain hollow area must be left between the two line cards 1, so that the cables on the two adjacent line cards 1 can be effectively prevented from contacting and rubbing, and the purpose of protecting the cables can be achieved to a certain extent.

[0037] Furthermore, the fixing clamp 3 includes an upper clamp 31 and a lower clamp 32, which are fixed by bolts and can be clamped on the line card 1. The upper clamp 31 and the lower clamp 32 can fix the end of the line card 1 and the cable on the line card 1. It should be noted that when multiple line cards 1 are stacked, the fixing clamps at the same end of the multiple line cards 1 can be fixed by the same bolt.

[0038] In order to facilitate the stacking of line cards 1, in some embodiments, see the attached Figure 3 As shown, the cross section of the line card 1 along the stacking direction is in the shape of an elliptical racetrack, so that at least part of the area of ​​the line card 1 is a plane. The cross section of the line card 1 is set to be in the shape of an elliptical racetrack, and the two straight sides (planes) of the elliptical racetrack shape can facilitate the arbitrary stacking of multiple line cards 1, and during the use of the drag chain cable, the contact with other equipment (workbench or ground) through the plane can increase the contact force area between the drag chain cable and other equipment, so as to minimize the damage to the surface of the drag chain cable and extend the service life of the drag chain cable.

[0039] In some embodiments, along the stacking direction, see the attached Figure 5 As shown, a keel layer 4 matching the shape of the line card 1 is provided on the inner side of the innermost line card 1, and a gap is left between the keel layer 4 and the innermost line card 1. Since the line cards 1 are mostly supported by flexible materials, by providing the keel layer 4 on the innermost side in the stacking direction, it does not affect any stacking of the multiple line cards 1, and can also enhance the support for the stacked multiple line cards 1.

[0040] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
