Description

Technical Field

[0001] This utility model relates to the field of cable chain technology, and more specifically, to a spliced ​​cable chain structure. Background Technology

[0002] Cable chains can concentrate the cables of mobile devices inside the chain, avoiding external friction and scratches, effectively extending the service life of the cables. In addition, cable chains can prevent cables from getting tangled and knotted, and protect the cables from environmental impacts.

[0003] Currently, cable chains are composed of multiple hinged links. Each link consists of a chain plate and a connecting rod. There are usually two chain plates and two connecting rods, which are installed between the two chain plates to form a link. However, the link width of most existing cable chains is usually fixed and cannot be adjusted according to usage requirements. When protecting the circuits of different numbers of devices, it is necessary to re-inject and process connecting rods of different lengths to adapt to the circuits of different devices. Re-injecting connecting rods not only requires a long time for mold design, wasting time and labor, but also increases production costs. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a splicing cable chain structure, which aims to solve the problem that the link width of the cable chain in the prior art is usually fixed and cannot be adjusted according to the usage requirements. When protecting the circuits of different numbers of equipment, it is necessary to re-inject and process connecting rods of different lengths to adapt to the circuits of different equipment. Re-injecting and molding connecting rods not only requires a long time for mold design, wasting time and labor, but also increases production costs.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution:

[0008] A splicing drag chain structure includes multiple sets of chain plates, which are sequentially hinged to each other via hinge pins. Each set of chain plates consists of two chain plates symmetrically distributed front and back, and a connecting component can be detachably connected between the two chain plates in each set.

[0009] Each of the connecting components includes multiple sets of connecting rods, which are detachably connected between two chain plates in each set. Each set of connecting rods consists of two rods arranged symmetrically in an up-down configuration, and an extension bracket is detachably connected between each pair of adjacent sets of connecting rods.

[0010] As a preferred embodiment of this utility model, each pair of chain plates has a side locking block fixedly connected to one end of each pair of chain plates, and the multiple side locking blocks are detachably connected to multiple connecting components.

[0011] As a preferred embodiment of this utility model, the upper and lower ends of the plurality of extended brackets are fixedly connected with support blocks, and the plurality of support blocks are detachably connected to the plurality of connecting rods.

[0012] As a preferred embodiment of this utility model, each pair of connecting rods is provided with a slot, and the multiple slots are respectively matched with multiple side blocks and multiple support blocks.

[0013] As a preferred embodiment of this utility model, connecting inserts are embedded in the two outermost sets of chain plates, and positioning protrusions are provided in the two outermost sets of chain plates.

[0014] 3. Beneficial effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] (1) In this solution, the cable chain is composed of multiple links. Each link consists of a set of two chain plates and a connecting component. Each connecting component contains multiple sets of connecting rods. Each pair of adjacent connecting rods is connected and supported by an extension bracket. Multiple extension brackets allow multiple sets of connecting rods to be spliced ​​on the inner side of each pair of two chain plates to form links. The spacing between each pair of two chain plates can be adjusted according to the number of splices of multiple sets of connecting rods and multiple extension brackets, thereby adjusting the width of each link and adjusting the overall width of the cable chain to adapt to equipment lines with different width requirements. In addition, as the overall width of the cable chain is adjusted, multiple extension brackets are adjusted according to the number of multiple sets of connecting rods. Multiple extension brackets are located inside the cable chain, which can improve the overall strength of the cable chain.

[0017] (2) In this solution, each set of connecting rods is designed to be two. The size of each connecting rod in multiple connecting components is the same. With the splicing of the extension bracket, different width drag chains can be assembled. Multiple connecting rods only need to be designed with a single mold and do not need to be re-injected to process connecting rods of different lengths, thus avoiding the waste of manpower and resources in re-injecting the connecting rods.

[0029] Example:

[0030] Please see Figure 1-6A splicing drag chain structure includes multiple sets of chain plates 1, which are sequentially hinged together by hinge pins. Each set of chain plates 1 consists of two chain plates symmetrically distributed front and back, and each set of two chain plates 1 is detachably connected to a connecting component 2.

[0031] Each connecting component 2 includes multiple sets of connecting rods 21, which are detachably connected between two chain plates 1 in each group. Each set of connecting rods 21 consists of two rods symmetrically distributed vertically. An extension bracket 3 can be detachably connected between each pair of adjacent sets of connecting rods 21.

[0032] In this embodiment, multiple sets of chain plates 1 are connected by hinges, and each connecting component 2 is installed inside each set of two chain plates 1 to form a complete cable chain. The equipment's wiring is protected inside the multiple sets of chain plates 1 and multiple connecting components 2. Each connecting component 2 consists of one or more connecting rods 21. Each set of connecting rods 21 consists of two rods, and adjacent sets of two connecting rods 21 are connected by an extension bracket 3. The multiple sets of connecting rods 21 of each connecting component 2 can adjust the width of the cable chain through the connection of multiple extension brackets 3, so that the cable chain can protect the equipment wiring for different needs. At the same time, the extension brackets 3 support each set of two connecting rods 21, ensuring the strength of the multiple sets of connecting rods 21, thereby improving the overall strength of the cable chain.

[0033] Specifically, each pair of chain plates 1 has a side locking block 4 fixedly connected to one end of each pair of chain plates 1, and the multiple side locking blocks 4 can be detachably connected to multiple connecting components 2.

[0034] In this embodiment, the side locking block 4 is disposed inside each set of chain plates 1, which can assemble and connect the connecting components 2, so that the connection of each connecting component 2 within a set of chain plates 1 remains stable.

[0035] Specifically, the upper and lower ends of the multiple extension brackets 3 are fixedly connected with support blocks 5, and the multiple support blocks 5 are detachably connected between multiple sets of connecting rods 21.

[0036] In this embodiment, each extension bracket 3 is connected to two adjacent sets of connecting rods 21 by two support blocks 5. The two support blocks 5 are engaged with the two sets of connecting rods 21, so that the connection between the two sets of connecting rods 21 is kept stable by the extension bracket 3 and the overall strength of the connecting assembly 2 is improved.

[0037] Specifically, each pair of connecting rods 21 has a slot 6, and the slots 6 are matched with multiple side blocks 4 and multiple support blocks 5 respectively.

[0038] In this embodiment, the side locking blocks 4 on each set of chain plates 1 and the two support locking blocks 5 on each extension bracket 3 are respectively inserted into multiple slots 6, so that multiple sets of chain plates 1, multiple connecting components 2 and multiple extension brackets 3 are assembled to form a drag chain.

[0039] Specifically, connecting inserts 7 are embedded on the two outermost chain plates 1, and positioning protrusions 8 are provided on the two outermost chain plates 1.

[0040] In this embodiment, the two outermost sets of chain plates 1 are located at both ends of the drag chain and are connected to the equipment through the connecting inserts 7 to protect the line. The positioning protrusions 8 are used to position the connection at both ends of the drag chain to keep the connection between the drag chain and the equipment stable.

[0041] Working principle: Based on the required width of the equipment line, each connecting component 2 selects the same number of multiple sets of connecting rods 21. The multiple sets of connecting rods 21 are engaged with the side locking blocks 4 in the multiple sets of chain plates 1 and the support locking blocks 5 on the multiple expansion brackets 3 through the slots 6 opened on themselves, thereby forming a complete drag chain to protect the equipment line. When protecting equipment lines with different width requirements, by increasing or decreasing the number of connecting rods 21 in each connecting component 2, the number of expansion brackets 3 is increased or decreased according to the number of multiple sets of connecting rods 21, so that the distance between the two chain plates 1 in each set is adjusted, thereby realizing the adjustment of the drag chain width to adapt to equipment lines with different width requirements.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
