Description

Technical Field

[0001] The utility model relates to the technical application field of drag chains, in particular to a drag chain convenient for installing wire harnesses. Background Art

[0002] A drag chain is composed of multiple chain links. A wire harness is assembled in a channel formed by multiple chain links. When the drag chain undergoes slight deformation and movement due to external force, the wire harness in the channel formed by multiple chain links deforms synchronously. Protecting the wire harness through a drag chain has been a conventional technical means for those skilled in the art. However, when installing a wire harness on an existing drag chain, the wire harness can only be placed in the channel of the drag chain by threading and pulling. Similarly, when the wire harness is damaged, personnel can only extract the wire harness in the channel, which is bound to affect the use of other wire harnesses.

[0003] Therefore, there is an urgent need to provide a drag chain convenient for installing wire harnesses. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a drag chain convenient for installing wire harnesses. One end connecting plate of the drag chain can be opened or closed, facilitating the installation and maintenance of the wire harness.

[0005] The technical solution of the utility model is: a drag chain convenient for installing wire harnesses, including a plurality of chain links. Each chain link includes two chain plates and two connecting plates. One of the connecting plates is fixed between the two chain plates to fix one side of the two chain plates. The other connecting plate is detachably arranged between the two chain plates to enclose the other side of the two chain plates to form a channel for placing the wire harness. The other connecting plate can open or close the channel.

[0006] Further, one end of the connecting plate is hinged to one of the chain plates, and the other chain plate is provided with a card slot. The other end of the connecting plate is detachably connected to the card slot through a buckle to fix the two chain plates.

[0007] Further, both ends of the connecting plate are provided with buckles, and the two chain plates are provided with card slots for cooperating with the buckles. The buckles are detachably connected to the card slots to fix the two chain plates.

[0008] Further, the two chain plates are arranged in a butt-jointed manner with respect to the connecting plate.

[0009] Further, the two connecting plates are arranged in parallel.

[0010] Further, two hinge areas are provided on each chain plate, with a limit port provided at any one of the hinge areas and a limit block provided at the other hinge area. When the chain link is connected to an adjacent chain link, the limit block is located within the limit port.

[0011] Further, the limiting block is a strip-shaped clamping block, and the limiting block moves along the edge of the limiting opening.

[0012] Further, the edge of the limiting opening is an arc-shaped structure, and corner blocks for cooperating with the limiting block are provided at both ends of the edge.

[0013] Further, first connecting pieces and second connecting pieces are respectively provided at both ends where several chain links are connected.

[0014] The beneficial technical effects of the present utility model are as follows:

[0015] 1. The detachable connection method of the connecting plate facilitates the installation and maintenance of the wire harness in the drag chain by personnel. Compared with the traditional drag chain that requires the wire harness to be drawn out, the installation efficiency and maintenance progress are improved.

[0016] 2. The setting of the limiting block and the limiting opening provides an activity gap between multiple chain links, ensuring that the movement of the components during the assembly of the drag chain will not damage the wire harness in the drag chain.

[0027] Embodiment 1:

[0028] As Figure 1-2 shown, the present utility model specifically relates to a drag chain for facilitating the installation of wire harnesses, which includes a plurality of chain links. Each chain link includes two chain plates 1 and two connecting plates 2. One of the connecting plates 2 is fixed between the two chain plates 1 to fix one side of the two chain plates 1, and the other connecting plate 2 is detachably disposed between the two chain plates 1 to enclose the other side of the two chain plates 1 to form a channel for placing the wire harness, and the other connecting plate 2 can open or close the channel.

[0029] It should be noted that the drag chain is composed of a plurality of chain links, and the wire harness is assembled in the channel formed by the plurality of chain links. When the drag chain undergoes slight deformation and movement due to external force, the wire harness located in the channel formed by the plurality of chain links deforms synchronously. Protecting the wire harness through the drag chain has already been a conventional technical means for those skilled in the art. Therefore, the connection method between the plurality of chain links will not be described in detail.

[0030] The chain link includes two chain plates 1 and two connecting plates 2. The two connecting plates 2 are respectively disposed at the upper and lower ends of the two connecting plates 2 to enclose the two chain plates 1 and form a channel for placing the wire harness. Among them, one connecting plate 2 is fixed between the two connecting plates 2, and the other connecting plate 2 is detachably disposed between the two connecting plates 2. In a detachable manner, the enclosed channel can be opened or closed, which not only facilitates personnel to assemble the wire harness into the channel without using the traditional method of threading the wire harness, but also facilitates personnel to repair the wire harness in the channel without using the traditional method of extracting the wire harness.

[0031] One end of the connecting plate 2 is hinged to one of the link plates 1, and the other link plate 1 is provided with a clamping groove 14. The other end of the connecting plate 2 is clamped to the clamping groove 14 through a buckle 21 to fix the two link plates 1.

[0032] There are various ways to detach the connecting plate 2. In this embodiment, one end of the connecting plate 2 is connected to one of the link plates 1 in a hinged manner, and the other end of the connecting plate 2 is clamped and connected to the clamping groove 14 of the other link plate 1 through the buckle 21.

[0033] When it is necessary to open the channel of the link, the buckle 21 is disengaged from the clamping groove 14. At this time, the connecting plate 2 flips along the hinge to open the channel, facilitating personnel to assemble or repair the wire harness.

[0034] The two link plates 1 are arranged in a buttressing manner relative to the connecting plate 2. Further, the link plates 1 in this application are designed in an axisymmetric manner, and this design can obtain higher stability. If the two link plates 1 are designed in parallel, it can also be used, but the anti-torsion effect will be reduced.

[0035] The two connecting plates 2 are arranged in parallel. Since the function of the connecting plate 2 is to enclose the link plates 1 to form a channel, one of the connecting plates 2 serves as a bearing plate for the wire harness, and the other connecting plate 2 serves as a cover plate for the channel. Therefore, it is only necessary to arrange the connecting plates 2 in parallel. Similarly, arranging the two connecting plates 2 in a buttressing manner can also be used, but the anti-torsion effect will be reduced.

[0036] Each of the link plates 1 is provided with two hinge areas 11. A limiting opening 13 is provided at any one of the hinge areas 11, and a limiting block 12 is provided at the other hinge area 11; when the link is connected to the adjacent link, the limiting block 12 is located within the limiting opening 13.

[0037] When the link is connected to the adjacent link, the limiting block 12 is located within the limiting opening 13. Obviously, the width of the limiting opening 13 determines the swing angle between the two links. In this application, through the design of directly opening the limiting opening 13 on the link plate 1, and the link plate 1 being the hardest part in the link, it is ensured that the size of the limiting opening 13 will not change over time, further improving the overall stability.

[0038] The limiting block 12 is a strip-shaped clamping block, and the limiting block 12 moves along the edge of the limiting opening 13; the edge of the limiting opening 13 is an arc-shaped structure, and corner blocks for cooperating with the limiting block 12 are provided at both ends of the edge.

[0039] The swing angle between the two links is further limited through the shape design of the limiting opening 13.

[0040] First connectors and second connectors are respectively provided at the two ends where several links are connected.

[0041] Example 2:

[0042] The structure of Example 2 is basically the same as that of Example 1, and the difference lies in: the detachable connection method of the connecting plate 2.

[0043] As Figure 2-4 shown, buckles 21 are provided at both ends of the connecting plate 2, and the two link plates 1 are provided with card slots 14 for cooperating with the buckles 21. The buckles 21 are detachably connected to the card slots 14 to fix the two link plates 1.

[0044] In this embodiment, by directly buckling the connecting plate 2 between the two link plates 1 with the buckles 21, the structure is simpler, and the number of connecting plates 2 can be reduced while ensuring the stability of the wire harness.

[0045] The above embodiments are only specific implementation manners of the present invention, used to illustrate the technical solutions of the present invention, rather than limiting it. The protection scope of the present invention is not limited thereto. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: any person skilled in the art within the technical scope disclosed by the present invention can still modify the technical solutions recorded in the foregoing embodiments or can easily think of changes, or perform equivalent replacements on some of the technical features; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be covered within the protection scope of the present invention.
