Description

Technical Field

[0001] This utility model relates to the field of cable accessories technology, and in particular to a cable chain that facilitates cable installation. Background Technology

[0002] A cable chain is a device used to organize and protect cables, oil pipes, and other pipelines. It is usually composed of multiple identical links that can be hinged together to form a flexible support structure. It is commonly used in fields such as automation equipment and robotics. It can extend or retract with the movement of mechanical equipment, thereby ensuring that the cables or other pipelines passing through it are not damaged due to excessive bending or stretching.

[0003] Traditional cable chain designs often require all the crossbars of the cable chain to be opened before cable installation can be carried out. At the same time, vertical partitions need to be installed to separate the conduits, so that multiple conduits inside the cable chain are arranged in an orderly manner, ensuring that the conduits inside the cable chain are not easily damaged. The whole process is complicated and time-consuming. Utility Model Content

[0004] To overcome the inconvenience of cable installation, which requires the cable chain crossbar to be fully opened for installation, this utility model provides a cable chain that is easy to install.

[0005] The technical solution of this utility model is: a cable chain that facilitates cable assembly, comprising:

[0006] An end connector, which is divided into a first connector and a second connector;

[0007] A chain link, comprising multiple links, is disposed between the first connector and the second connector. Each chain link includes: a link body having multiple tapered holes, one side of which has a larger diameter than the other, for cable passage; and...

[0008] A snap-fit ​​structure is provided on the section body and the end connector, and the section bodies are connected to each other and the section body and the end connector are connected by the snap-fit ​​structure.

[0009] As a preferred embodiment of this utility model, the snap-fit ​​structure includes:

[0010] The locking block is located at the same end on both the front and rear sides of the segment body. The other end of both the front and rear sides of the segment body is provided with locking holes. The locking block and locking holes are respectively located at the two ends on the front and rear sides of the first connector and the second connector. The shape of the locking hole is adapted to the locking block. The side of the locking block away from the segment body or the first connector is provided with a bevel.

[0011] As a preferred technical solution of this utility model, the end of the segment body with the locking hole is semi-circular arc-shaped, and the end of the segment body with the locking block is provided with a rotating groove that matches the semi-circular arc-shaped end with the locking hole.

[0012] As a preferred technical solution of this utility model, the snap-fit ​​structure allows the segment body to rotate at a certain angle relative to the adjacent segment body or end joint.

[0013] As a preferred technical solution of this utility model, the inner side of the end of the segment body with the card hole contacts the outer side of the end of the segment body with the card block.

[0014] As a preferred technical solution of this utility model, it also includes:

[0015] The limiting block is located on one end of the front and rear sides of the section body near the card hole, and the other end has a limiting groove that matches the limiting block.

[0016] As a preferred technical solution of this utility model, the front and rear parts of the chain body have a certain degree of elasticity.

[0017] As a preferred technical solution of this utility model, the diameter of the smallest part of the tapered hole is slightly larger than the cross-section of the cable.

[0018] As a preferred technical solution of this utility model, both the first connector and the second connector have multiple mounting holes.

[0019] As a preferred embodiment of this invention, the number of chain links can be increased or decreased according to actual needs.

[0020] Compared with the prior art, the present invention has the following advantages: 1. The present invention uses a chain link design, in which the chain link is a complete unit. One chain link includes the traditional left and right side plates, vertical partitions and crossbars, which has the advantages of convenient assembly, simple structure and saving parts. Through the design of the tapered hole, the cable chain can be quickly installed through the tapered hole when installing the cable conduit, without having to open all the crossbars of the cable chain before installation, thus improving assembly efficiency.

[0021] 2. This utility model prevents damage to the internal cable caused by excessive rotation between two chain links through the design of the limiting block and the limiting groove; through the design of the tapered hole diameter, a certain small gap is reserved while fixing the cable, avoiding excessive compression of the cable due to the dynamic bending of the drag chain.

[0028] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0029] A cable chain that facilitates cable assembly, such as Figures 1-5 As shown, it includes an end connector 1 and chain links 2. The end connector 1 includes a first connector 101 and a second connector 102. Multiple chain links 2 are connected between the first connector 101 and the second connector 102. Each chain link 2 includes a link body 201 and a snap-fit ​​structure. Multiple tapered holes 202 are evenly provided on the link body 201 from front to back. The diameter of one side of the tapered hole 202 is larger than that of the other side. The tapered holes 202 are used for cables to pass through. Snap-fit ​​structures are provided on the front and rear sides of the link body 201 and the end connector 1. The link bodies 201 are connected to each other through snap-fit ​​structures, and the link bodies 201 and the end connector 1 are connected through snap-fit ​​structures.

[0030] During assembly, the first connector 101, the second connector 102, and the chain link 2 are assembled by snap-fit ​​structure. When installing the cable tube 3, the assembled cable chain is first arranged in a straight line. Then, the cable tube 3 is inserted from the side with the larger diameter of the tapered hole 202 to the side with the smaller diameter, so that the cable tube 3 can be quickly installed into the chain link 2. This process is repeated several times until the cable tube 3 is completely installed into the cable chain.

[0031] like Figures 2-5As shown, the snap-fit ​​structure includes snap-fit ​​blocks 203. Snap-fit ​​blocks 203 are provided at one end of both the front and rear sides of the main body 201, and snap-fit ​​holes 204 are provided at the other end of both the front and rear sides of the main body 201. Snap-fit ​​blocks 203 and snap-fit ​​holes 204 are provided at both ends of the front and rear sides of the first connector 101 and the second connector 102, respectively. The shape of the snap-fit ​​hole 204 is adapted to the snap-fit ​​block 203. A bevel is provided on the side of the snap-fit ​​block 203 away from the main body 201 or the first connector 101. When the snap-fit ​​block 203 of an adjacent link 2 or end connector 1 is aligned with the snap-fit ​​hole 204, the snap-fit ​​blocks 203 on both the front and rear sides can be inserted into the snap-fit ​​hole 204 to complete the assembly. The bevel design facilitates insertion and makes assembly more convenient.

[0032] The end of the section body 201 with the locking hole 204 is semi-circular arc-shaped, and the end of the section body 201 with the locking block 203 is provided with a rotating groove that matches the semi-circular arc-shaped end with the locking hole 204. The locking structure allows the section body 201 to rotate a certain angle relative to the adjacent section body 201 or the end connector 1.

[0033] The inner side of the end of the link body 201 with the locking hole 204 contacts the outer side of the end of the link body 201 with the locking block 203. This contact method can provide stable support and positioning, ensuring that the link will not shake or deviate too much when rotating, thus ensuring the stability and reliability of the drag chain structure.

[0034] like Figures 2-4 As shown, it also includes a limiting block 205. The limiting block 205 is provided at one end of the front and rear sides of the main body 201 near the card hole 204, and the other end has a limiting groove 206 adapted to the limiting block 205. When the cable chain bends, the limiting block 205 and the limiting groove 206 can prevent the cable from being damaged due to excessive rotation between the two chain links 2.

[0035] The front and rear parts of the chain body have a certain degree of elasticity. When the locking block 203 of the adjacent chain link 2 or the end joint 1 is aligned with the locking hole 204, the elastic deformation allows the chain body to undergo slight bending or compression locally, making it easier for the locking block 203 to slide into the locking hole 204.

[0036] The smallest part of the tapered hole 202 has a diameter slightly larger than the cross-section of the cable, which leaves a small gap while fixing the cable to prevent the cable from being damaged by excessive compression due to the dynamic bending of the cable chain.

[0037] The first connector 101 and the second connector 102 each have multiple mounting holes 103. The mounting holes 103 provide a fixing interface, which makes it easy to install both ends of the cable chain to the designated position of the equipment using fasteners such as bolts.

[0038] The number of links in link 2 can be increased or decreased according to actual needs to accommodate cables of different lengths.

[0039] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
