Description
Technical Field
[0001] This utility model relates to the field of cable protection chain technology, specifically to a flexible cable protection chain. Background Technology
[0002] Cable protection chains are used to encase cables to prevent damage from dust, moisture, and external mechanical forces. Existing cable protection chains typically have a single, hollow internal structure. When multiple cables are run through the same chain, the lack of effective separation and restraint between the cables makes them prone to entanglement, compression, and friction during use. Over long-term operation, friction causes insulation wear, posing safety hazards. Entanglement and displacement between cables also affect signal transmission stability and reduce the reliability of the device. Furthermore, existing nylon cable protection chains may cause internal cables to shift or stack during bending or movement, further exacerbating wear and deformation and shortening cable lifespan.
[0003] Therefore, the existing flexible cable protection chains still have shortcomings in their internal structural design, and cannot effectively prevent multiple cables from getting tangled and worn inside the corrugated pipe. It is urgent to improve their structure to enhance the stability of the cable arrangement in the protection chain and the overall protection performance. Utility Model Content
[0004] To overcome the above shortcomings, the purpose of this utility model is to provide a flexible cable protection chain. By setting a partition inside the corrugated pipe, the internal space is divided into multiple cable grooves, so that the cables are arranged independently inside the corrugated pipe, avoiding mutual entanglement and wear, thereby improving the protection effect and service life of the cables.
[0005] Technical solution: This utility model discloses a flexible cable protection chain, comprising:
[0006] A corrugated pipe for fully enclosed housing of a cable, the corrugated pipe being made of a flexible material;
[0007] Two cable connectors, one of which is fixedly sealed to one end of the corrugated pipe along its length, and the cable extends out of the corrugated pipe and passes through the cable connector;
[0008] Multiple partitions are spaced apart along the length of the corrugated pipe inside the corrugated pipe, thereby dividing the interior of the corrugated pipe into several cable grooves for the cable to pass through.
[0009] Furthermore, the cable connector includes an upper cover plate and a lower cover plate that can be interlocked and fixed together. The upper cover plate has a plurality of upper fixing teeth parallel to the length direction of the cable at the end away from the corrugated pipe. The lower cover plate has a plurality of lower fixing teeth parallel to the length direction of the cable at the end away from the corrugated pipe. The cable in the cable groove above the partition is fixed to the upper fixing teeth, and the cable in the cable groove below the partition is fixed to the lower fixing teeth.
[0010] Furthermore, the upper cover plate also has an upper mounting hole for fixing the cable connector to an external device; the lower cover plate also has a lower mounting hole for fixing the cable connector to an external device.
[0011] Furthermore, the partition includes a transverse partition and two longitudinal partitions that are perpendicular to the transverse partition and parallel to each other, with both ends of the transverse partition and the longitudinal partition abutting against the inner wall of the bellows.
[0012] Furthermore, the partition includes two longitudinal partitions and two transverse partitions. The two longitudinal partitions are parallel to each other and abut against the inner wall of the bellows. There is a cavity between the two longitudinal partitions for accommodating the keel chain. One transverse partition is disposed on the side of one of the longitudinal partitions opposite to the cavity and perpendicular to it. The other end of the transverse partition abuts against the inner wall of the bellows.
[0013] Furthermore, the keel chain includes several keels connected end to end in sequence. Each keel includes a slot and a locking block. The locking block of any one keel can extend into the slot of another keel. The locking block has fixing posts on both sides. The inner wall of the slot has a guide groove for guiding the fixing posts and a mounting hole for locking the fixing posts.
[0014] Furthermore, the bellows is made of ETPU.
[0015] Furthermore, any two adjacent partitions are 10cm apart.
[0016] Furthermore, the keel is made of Teflon.
[0017] The beneficial effects of this utility model are as follows:
[0018] (1) This utility model divides the internal space of the corrugated pipe into multiple independent cable grooves by uniformly setting several partitions along the length direction inside the corrugated pipe, so that multiple cables can maintain their own fixed channels inside the corrugated pipe, avoid mutual friction and entanglement between cables, reduce the risk of insulation layer wear, and improve the safety and service life of the cable.
[0019] (2) The corrugated pipe is made of ETPU material, which has good flexibility and wear resistance and can adapt to the working environment of frequent bending and multi-directional movement; the keel chain is made of Teflon material, which has low friction coefficient and corrosion resistance. It can reduce wear and jamming while ensuring guidance and fixing, so that the flexible cable protection chain can still maintain stable cable guidance and protection effect in complex working environment, and extend the service life of the entire protection chain and cable.

The implementation methods of this utility model will now be described based on its overall structure.
[0033] like Figures 1 to 9 As shown, this utility model discloses a flexible cable protection chain, comprising:
[0034] Corrugated pipe 1, which is used to fully enclose the cable, is made of flexible material;
[0035] Two cable connectors 2, one of which is fixedly sealed to one end of the corrugated pipe 1 along its length, and the cable extends out of the corrugated pipe 1 and passes through the cable connector 2;
[0036] Multiple partitions 3 are spaced apart inside the corrugated pipe 1 along its length, thereby dividing the interior of the corrugated pipe 1 into several cable grooves 34 for the cable to pass through.
[0037] With the above structure, the corrugated pipe 1 serves as the main structure, protecting the multiple cables housed within it. The corrugated pipe 1 is made of a flexible material with good bending and compressive strength, allowing the cable chain to bend freely in complex working environments while effectively preventing cable damage due to frequent vibration. A cable connector 2 is located at one end of the corrugated pipe 1 and is sealed to it, thus extending the cable's service life. The cable extends from the corrugated pipe 1 and passes through the cable connector 2, where it is stably positioned to prevent slippage. The corrugated pipe 1 is made of ETPU material. ETPU material combines the high elasticity of rubber with the high strength of plastic, possessing excellent flexibility, wear resistance, and fatigue resistance. This allows the corrugated pipe 1 to maintain good deformation recovery during frequent bending or dynamic movement, making it less prone to breakage or permanent deformation.
[0038] Inside the corrugated pipe 1, several partitions 3 are evenly distributed along its length. These partitions 3 divide the internal space of the corrugated pipe 1 into multiple independent cable trays 34, each capable of accommodating a cable. Therefore, different cables are arranged independently within the corrugated pipe 1, preventing insulation wear caused by cable compression or friction, thus improving cable safety. Furthermore, any two adjacent partitions 3 are 10cm apart, and the partitions 3 are evenly distributed along the length of the corrugated pipe 1. The spacing between adjacent partitions 3 ensures the stability of the internal structure of the corrugated pipe 1 while also allowing sufficient space for cable movement during installation and bending. By setting partitions 3 at fixed intervals, the corrugated pipe 1 maintains overall flexibility while providing good internal support, preventing internal cable twisting or friction due to bending or external compression, thereby further improving the service life and safety performance of the cable protection chain.
[0039] like Figure 7 As shown, any cable connector 2 includes an upper cover plate 21 and a lower cover plate 22 that can be snapped together and fixed. The two are connected by a snap-fit mechanism, thereby covering and locking the end of the corrugated pipe 1 and the cable passing through the cable connector 2. At the cable outlet of the cable connector 2, the upper cover plate 21 has several upper fixing teeth 211 arranged parallel to the cable length direction at the end away from the corrugated pipe 1, and the lower cover plate 22 has several lower fixing teeth 221 that cooperate with it at the corresponding position.
[0040] The upper fixing teeth 211 and lower fixing teeth 221 are arranged along the length of the cable, thereby providing independent positioning and support for the cable. Specifically, the cable in the cable groove 34 above the partition 3 is fixed to the upper fixing teeth 211, and the cable in the cable groove 34 below the partition 3 is fixed to the lower fixing teeth 221. In use, to improve the fixing effect and prevent friction damage to the cable at the joint due to vibration or displacement, a flexible silicone sleeve can be fitted between the cable and the upper fixing teeth 211 and / or the lower fixing teeth 221 to fix them together. Through the cooperation of the silicone sleeve and the fixing teeth, each cable can be independently fixed, avoiding tangling and keeping the cable exit direction consistent.
[0041] The upper cover plate 21 also has an upper mounting hole 212 for fixing the cable connector 2 to an external device, and the lower cover plate 22 has a corresponding lower mounting hole 222 for fixing the cable connector 2 to an external device. The upper mounting hole 212 and the lower mounting hole 222 are coaxially arranged after the upper cover plate 21 and the lower cover plate 22 are closed, allowing fasteners to pass through and fix the cable connector 2, thereby achieving a stable connection between the cable connector 2 and the external device. With this structure, the cable connector 2 can be easily and directly fixed to external components such as control boxes, equipment housings, or brackets during installation, thereby controlling the bending and movement of the cable.
[0042] In one feasible embodiment, such as Figure 3 , Figure 4 and Figure 6 As shown, the partition 3 includes a transverse partition 31 and two longitudinal partitions 32 that are perpendicular to the transverse partition 31 and parallel to each other. The transverse partition 31 extends radially along the corrugated pipe 1 and is located at the center of the interior of the corrugated pipe 1, thereby initially dividing the internal space of the corrugated pipe 1 vertically. The two longitudinal partitions 32 are perpendicular to the transverse partition 31 and are located inside the corrugated pipe 1. The transverse partition 31 and the longitudinal partitions 32 can be connected by insertion. Both ends of the transverse partition 31 and the longitudinal partitions 32 abut against the inner wall of the corrugated pipe 1, thereby forming multiple independent cable channels inside the corrugated pipe 1 that can be used for cable passage. Without affecting the flexibility of the corrugated pipe 1, the partition 3 can stably limit the arrangement position of multiple cables, avoiding mutual compression, friction, or entanglement between cables that could cause damage to the insulation layer.
[0043] In another feasible embodiment, such as Figure 5 , Figure 8 and Figure 9As shown, when the length of the corrugated pipe 1 is greater than 1.5m, a keel chain 4 is also installed inside the corrugated pipe 1. The keel chain 4 provides strong support and maintains the bending radius to prevent collapse. Specifically, the partition 3 includes two longitudinal partition plates 32 and two transverse partition plates 31. The two longitudinal partition plates 32 are arranged parallel to each other, and both ends of them abut against the inner wall of the corrugated pipe 1. A cavity 33 is provided between the two longitudinal partition plates 32 to accommodate the keel chain 4. The cavity 33 extends along the length of the corrugated pipe 1, providing a stable installation channel for the keel chain 4, so that the keel chain 4 provides support during the bending or movement of the corrugated pipe 1.
[0044] Furthermore, a transverse partition 31 is disposed on the side of one of the longitudinal partitions 32 opposite to the cavity 33 and perpendicular to the longitudinal partition 32. The other end of the transverse partition 31 abuts against the inner wall of the corrugated pipe 1, thereby further dividing the internal space of the corrugated pipe 1 into several independent areas for cable passage. The partition 3 inside the corrugated pipe 1 can effectively limit the position of the keel chain 4, preventing it from swinging or shifting during the bending movement of the corrugated pipe 1, and can also provide independent passages for multiple cables, avoiding friction or entanglement between multiple cables.
[0045] The keel chain 4 comprises several keels 4 connected end to end. Each keel 4 includes a slot 42 and a locking block 41. Two adjacent keels 4 are connected by the interlocking of the slot 42 and the locking block 41. The locking block 41 of any keel 4 can extend into the slot 42 of an adjacent keel 4, thereby forming a flexible hinged connection structure between adjacent keels 4. The locking block 41 has fixing posts 411 on both sides for positioning in conjunction with the slot 42 of the adjacent keel 4. Correspondingly, the inner wall of the slot 42 has a guide groove 421 extending in the insertion direction and a mounting hole 422 connected to the guide groove 421. When two keels 4 are connected, the fixing post 411 is accommodated in the mounting hole 422. During assembly, the fixing post 411 first slides into the slot 42 along the guide groove 421. As the locking block 41 is gradually inserted, the fixing post 411 is finally embedded in the mounting hole 422 and locked in place, achieving a reliable connection between the two keels 4. The entire keel chain 4 can be freely bent within a certain range to adapt to the deformation requirements of the corrugated pipe 1 under different bending angles or motion conditions. The keel 4 is made of Teflon, which has excellent wear resistance, corrosion resistance, and an extremely low coefficient of friction, allowing the keel chain 4 to maintain good structural stability and smooth sliding performance during long-term movement or repeated bending. Furthermore, the smooth surface of the Teflon material makes it difficult for impurities to adhere, effectively reducing the frictional resistance between the keel chain 4 and the inner wall of the corrugated pipe 1, avoiding dust or debris generated by wear, and extending the service life of the cable protection chain.
[0046] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
