Description

Technical Field

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

[0002] In modern industry, cable chains are a key component widely used in machine tools, machinery, and various automated equipment. Current cable chain technology is relatively mature, and the market offers a wide variety of cable chain products with diverse design concepts, all designed to meet the diverse usage requirements of different machines.

[0003] However, in-depth research and feedback from practical applications have revealed that current cable chains suffer from insufficient sealing. Many cable chains have gaps at the connection between the upper and lower shells. This defect allows dust, debris, liquids, and other impurities to easily enter the cable chain, damaging protected components such as cables and pipes, affecting normal equipment operation, and reducing its lifespan and stability. For example, in dusty processing environments, dust can enter the cable chain through these gaps and adhere to the cable surface. Prolonged dust accumulation can lead to short circuits and other malfunctions, increasing maintenance costs and the risk of equipment downtime.

[0004] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0005] The purpose of this invention is to provide a sealed cable chain.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A sealed cable chain, comprising:

[0008] The first enclosure and the second enclosure together form a protective space;

[0009] The first locking assembly and the second locking assembly are respectively provided on the first enclosure and the second enclosure to lock the enclosure state of the first enclosure and the second enclosure.

[0010] The first sealing component and the second sealing component are respectively provided on the first enclosure and the second enclosure, and are used to seal the part of the contact surface between the first enclosure and the second enclosure when they are in the enclosure state.

[0011] The first locking assembly and the second locking assembly are respectively provided on the first enclosure and the second enclosure. Specifically, the first locking assembly is connected to the first enclosure and the second locking assembly is connected to the second enclosure. The connection method is not limited here.

[0012] The first enclosure and the second enclosure together form a protective space, which is used to protect the objects inside.

[0013] The first locking assembly and the second locking assembly are locked together to achieve a stable fit between the first enclosure and the second enclosure, thereby improving the stability of the protected space and preventing debris from entering the protected space through the gap between the first enclosure and the second enclosure.

[0014] The term "avoiding debris from entering the protected space" in this application means to avoid it as much as possible. In reality, a very small amount of debris may enter the protected space during the long-term use of the sealed cable chain.

[0015] By utilizing the cooperation of the first sealing component and the second sealing component, debris is further prevented from entering the protective space through the gap between the first enclosure and the second enclosure, thereby improving the sealing performance of the protective space. This makes the cable chain in this application particularly suitable for scenarios with high requirements for sealing performance and protection capabilities, thus expanding the application scope of the cable chain.

[0016] Taking the first sealing assembly as an example, in some embodiments the first sealing assembly can be regarded as part of the first enclosure, and the two cannot be considered as separate structures.

[0017] In summary, the first locking assembly and the second locking assembly lock the first enclosure and the second enclosure, and can also be used to improve the sealing performance of the cable chain. The first sealing assembly and the second sealing assembly are mainly used to improve the sealing performance of the cable chain, but can also be used to improve the assembly stability of the first enclosure and the second enclosure.

[0018] In a further technical solution, the first enclosure member and the second enclosure member are fitted together along a first direction;

[0019] The protective space has one or two openings along its length;

[0020] The first direction is perpendicular to the length direction of the protective space.

[0021] See Figure 1 The first enclosure and the second enclosure form a continuous sealing structure, preventing debris from directly passing through this continuous sealing structure and entering the protected space.

[0022] Cable chains are typically used in combination. Therefore, the sealing ability of a cable chain is mainly judged based on the difficulty of debris entering the protected space through the gap between the first enclosure and the second enclosure.

[0023] The protective space has two openings along its length, allowing multiple cable chains to be used together, thus improving the ease of cable chain coordination.

[0024] The protective space has a single opening along its length, and this type of cable chain can be installed at the end when multiple cable chains are used together.

[0025] A further technical solution is that, along the length of the protective space, the two end faces of the first enclosure member and the two end faces of the second enclosure member are arranged parallel to each other.

[0026] And / or, along the length of the protective space, both end faces of the first enclosure and both end faces of the second enclosure are straight surfaces;

[0027] And / or, along the length of the protective space, any adjacent end faces of the first enclosure and the second enclosure are on the same plane.

[0028] Along the length of the protective space, the two end faces of the first enclosure and the two end faces of the second enclosure are arranged parallel to each other, as explained below: the four end faces are parallel to each other, which facilitates the use of multiple cable chains and also facilitates the manufacture of cable chains, reducing manufacturing costs.

[0029] Along the length of the protective space, both ends of the first enclosure and both ends of the second enclosure are straight, as explained below: This also facilitates the use of multiple cable chains, further reducing the difficulty of manufacturing cable chains.

[0030] Along the length of the protective space, any adjacent end faces of the first enclosure and the second enclosure are on the same plane, as explained below: In this case, along the length of the protective space, the first enclosure and the second enclosure have the same dimensions, which also facilitates the use of multiple cable chains.

[0031] When the above three methods are used in combination, on the one hand, the processing difficulty of the cable chain can be significantly reduced, thereby reducing costs; on the other hand, the convenience of using the cable chain can be significantly improved; and on the third hand, the sealing performance of the cable chain can also be improved.

[0032] In a further technical solution, the mating surfaces of the first enclosure and the second enclosure form multiple continuous sealing interfaces.

[0033] Taking two continuous sealing interfaces as an example, along the width direction of the protected space (or the width direction of the cable chain), the two continuous sealing interfaces are located on both sides of the protected space to prevent debris from entering the protected space. The continuous sealing interfaces have continuity to improve the sealing performance of the cable chain.

[0034] In a further technical solution, the first locking assembly includes a connecting section and a locking section connected to each other, wherein the connecting section is connected to the first enclosure member;

[0035] In the width direction of the protected space, the size of the locking segment is larger than the size of the connecting segment;

[0036] The second enclosure is provided with a first groove corresponding to the connecting section and a second groove corresponding to the locking section. The first groove and the second groove are connected and constitute the second locking assembly.

[0037] The sealed cable chain is in an assembled state:

[0038] In the assembled state, the connecting section and the locking section are placed one-to-one in the first groove and the second groove, and the locking section and the second groove cooperate to restrict the relative movement of the first enclosure and the second enclosure along the thickness direction of the protective space.

[0039] For ease of understanding, the combination of the connecting section and the locking section can be regarded as a T-shaped locking block, and the combination of the first groove and the second groove can be regarded as a T-shaped locking groove. When the T-shaped locking block is assembled in the T-shaped locking groove, it can only move along the length of the protective space to separate the two. This can ensure the assembly stability of the first enclosure and the second enclosure, and facilitate the quick separation of the first enclosure and the second enclosure when necessary.

[0040] This embodiment clarifies a specific method for locking the first enclosure and the second enclosure, thereby improving the stability and sealing of the protective space by stably locking the first enclosure and the second enclosure.

[0041] In a further technical solution, the first enclosure is provided with a third groove, which constitutes the first locking assembly.

[0042] A portion of the surface of the second enclosure is provided with protrusions to form locking protrusions corresponding to the third groove, the locking protrusions constituting the second locking assembly;

[0043] The sealed cable chain is in an assembled state:

[0044] In the assembled state, along the thickness direction of the protective space, the wall of the third groove body is attached to the symmetrical two side surfaces of the locking protrusion to restrict the relative movement of the first enclosure member and the second enclosure member along the thickness direction of the protective space.

[0045] For ease of understanding, the third groove is provided with a first sidewall, a second sidewall, and a bottom wall. The first and second sidewalls are symmetrically arranged in the thickness direction of the protective space, and the first sidewall is positioned above the second sidewall. In the assembled state, both the first and second sidewalls are in contact with the locking protrusion, and the first sidewall restricts the movement of the locking protrusion relative to the third groove along the thickness direction of the protective space.

[0046] This embodiment clarifies another specific method for locking the first enclosure and the second enclosure, which also improves the stability and sealing of the protective space by stably locking the first and second enclosures. Both methods can be used selectively to meet different needs.

[0047] In a further technical solution, the first enclosure is provided with a fourth groove, and the fourth groove constitutes the first sealing assembly.

[0048] A portion of the surface of the second enclosure is provided with protrusions to form a sealing protrusion corresponding to the fourth groove, the sealing protrusion constituting the second sealing assembly;

[0049] The sealed cable chain is in an assembled state:

[0050] In the assembled state, the sealing protrusion is fitted against the wall of the fourth groove to form a continuous sealing assembly surface.

[0051] Due to limitations in processing difficulty and processing cost, there is a gap between the first enclosure and the second enclosure, and the gap between the first locking assembly and the second locking assembly may be even larger, such as when the two are not perfectly matched in size to avoid high assembly difficulty.

[0052] This embodiment clarifies a specific arrangement of the first and second sealing components. By forming a continuous sealing assembly surface, it prevents debris from entering the protected space through the gap between the first and second enclosure components, thereby improving the sealing performance of the protected space. This makes the cable chain in this application particularly suitable for scenarios with high requirements for sealing and protection capabilities, expanding the applicability of the cable chain. This also reduces the precision requirements for the processing of the first and second enclosure components, thereby reducing processing costs.

[0053] In a further technical solution, in the assembled state, the projection of the continuous sealing assembly surface along the length direction of the protective space intersects with a vertical plane at least twice.

[0054] For ease of understanding, the projection of the continuous sealing assembly surface along the length of the protected space is set to be arc-shaped, with a central angle of 200 degrees (adjustable). See [reference needed]. Figure 2 .

[0055] This embodiment restricts the continuous sealing assembly surface. Based on this, the continuous sealing assembly surface itself can restrict the relative movement of the first enclosure and the second enclosure in the thickness direction of the protective space, thereby improving the assembly stability of the first enclosure and the second enclosure while ensuring the sealing effect.

[0056] In a further technical solution, in the width direction of the protective space, the first locking device is located between the first sealing device and the protective space;

[0057] Alternatively, in the width direction of the protective space, the first sealing device is positioned between the first locking device and the protective space.

[0058] See Figure 4 In the width direction of the protected space, the first locking assembly is located between the first sealing assembly and the protected space, and the second locking assembly corresponds to the first locking assembly. Therefore, the second locking assembly is located between the second sealing assembly and the protected space. Based on this, the sealing structure is relatively external, resulting in stronger sealing performance of the cable chain.

[0059] See Figure 6 In the width direction of the protected space, the first sealing assembly is positioned between the first locking assembly and the protected space. Based on this, more processing requirements can be met, such as adaptive design and processing according to the shapes of the first and second enclosures.

[0060] In a further technical solution, the first locking assembly and the second locking assembly form a locking structure, and there are two locking structures arranged in parallel in the width direction of the protected space.

[0061] The first sealing component and the second sealing component together form a sealing structure. There are two sealing structures, which are arranged in parallel in the width direction of the protected space.

[0062] The following descriptions use locking structures as examples; the sealing structure is described in the same way.

[0063] In some embodiments, two locking structures are provided at one end of the cable chain along the width of the protected space to further improve the stability of the cable chain.

[0064] In some embodiments, two locking structures are respectively disposed at both ends of the cable chain along the width direction of the protective space to further improve the sealing and stability of the cable chain; the above embodiments can be regarded as covering the schemes of being disposed at one end of the cable chain and being disposed at both ends of the cable chain, and this part limits this.

[0065] When two locking structures are set in parallel, they can be arranged symmetrically (see [reference]). Figure 6Alternatively, an asymmetrical setup can be used. In an asymmetrical setup, the two locking structures can overlap by translation. Both setups are suitable for different processing modes, making this application applicable to different processing equipment.

[0066] The terms "first," "second," etc., used in this article do not specifically refer to order or sequence, nor are they intended to limit this case; they are merely used to distinguish components or operations described using the same technical terms.

[0067] The terms "connection" or "positioning" as used in this article can refer to two or more components or devices making direct physical contact with each other, or making indirect physical contact with each other, or to two or more components or devices operating or moving with each other.

[0068] The terms “include,” “including,” and “have” used in this article are all open-ended, meaning they include but are not limited to.

[0069] Unless otherwise specified, the terms used herein generally have their ordinary meaning in the context of the art, the subject matter, and the specific context. Certain terms used to describe this case will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the case.

[0070] The terms “front,” “back,” “up,” “down,” “left,” and “right” used in this article are directional terms. In this case, they are only used to describe the positional relationship between the structures and are not intended to limit the specific direction of the protection scheme or its actual implementation.

[0071] The working principle and advantages of this utility model are as follows:

[0072] The first locking assembly and the second locking assembly are locked together to achieve a stable fit between the first enclosure and the second enclosure, thereby improving the stability of the protected space and preventing debris from entering the protected space through the gap between the first enclosure and the second enclosure.

[0073] By utilizing the cooperation of the first sealing component and the second sealing component, debris is further prevented from entering the protective space through the gap between the first enclosure and the second enclosure, thereby improving the sealing performance of the protective space. This makes the cable chain in this application particularly suitable for scenarios with high requirements for sealing performance and protection capabilities, thus expanding the application scope of the cable chain.

[0074] In summary, the first and second locking assemblies lock the first and second enclosure components, and also improve the sealing performance of the cable chain. While primarily used to enhance the sealing performance of the cable chain, the first and second sealing assemblies can also improve the assembly stability of the first and second enclosure components. Furthermore, this application features a simple structure, controllable cost, and enables rapid assembly, reducing operating costs. Attached Figure Description

[0082] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0083] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0084] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0085] See Figures 1-6 A sealed cable chain, comprising:

[0086] The first enclosure 1 and the second enclosure 2 together form a protective space 3;

[0087] The first locking assembly 4 and the second locking assembly 5 are respectively provided on the first enclosure 1 and the second enclosure 2, and are used to lock the enclosure state of the first enclosure 1 and the second enclosure 2.

[0088] The first sealing component 6 and the second sealing component 7 are respectively provided on the first enclosure 1 and the second enclosure 2, and are used to seal the part of the contact surface between the first enclosure 1 and the second enclosure 2 when they are in the enclosure state.

[0089] The first locking assembly 4 and the second locking assembly 5 are respectively provided on the first enclosure 1 and the second enclosure 2. Specifically, the first locking assembly 4 is connected to the first enclosure 1, and the second locking assembly 5 is connected to the second enclosure 2. The connection method is not limited here.

[0090] The first enclosure 1 and the second enclosure 2 enclose each other to form a protective space 3, which is used to protect the internal objects.

[0091] The first locking assembly 4 and the second locking assembly 5 are locked together to achieve a stable fit between the first enclosure 1 and the second enclosure 2, thereby improving the stability of the protective space 3 and preventing debris from entering the protective space 3 through the gap between the first enclosure 1 and the second enclosure 2.

[0092] The phrase "avoiding debris from entering the protected space 3" in this application means to avoid it as much as possible. In reality, a very small amount of debris may enter the protected space 3 during the long-term use of the sealed cable chain.

[0093] By utilizing the cooperation of the first sealing component 6 and the second sealing component 7, debris is further prevented from entering the protective space 3 through the gap between the first enclosure 1 and the second enclosure 2, thus improving the sealing performance of the protective space 3. This makes the cable chain in this application particularly suitable for scenarios with high requirements for sealing and protection capabilities, expanding the applicability of the cable chain. For example, in some dusty processing environments, since dust is difficult to enter the protective space 3 through the gap between the first enclosure 1 and the second enclosure 2, it avoids short circuits and other malfunctions, reduces maintenance costs and equipment downtime risks, and ensures the service life and stability of the equipment.

[0094] Taking the first sealing component 6 as an example, in some embodiments the first sealing component 6 can be regarded as part of the first enclosure 1, and it cannot be considered that the two can only be separately set structures.

[0095] In summary, the first locking assembly 4 and the second locking assembly 5 lock the first enclosure 1 and the second enclosure 2, and can also be used to improve the sealing performance of the cable chain. The first sealing assembly 6 and the second sealing assembly 7 are mainly used to improve the sealing performance of the cable chain, but can also be used to improve the assembly stability of the first enclosure 1 and the second enclosure 2. Furthermore, this application has a simple structure, controllable cost, and can achieve rapid assembly, reducing operating costs.

[0096] See Figures 1-6 In this embodiment, the first enclosure 1 and the second enclosure 2 are fitted together along the first direction;

[0097] The protective space 3 has one or two openings along its length;

[0098] The first direction is perpendicular to the length direction of the protective space 3.

[0099] For the cable chain and the protective space 3, both are set to have the same length, width, and thickness directions, with the length direction parallel to the x-axis. Figure 1 In the x-direction, the width direction is parallel to Figure 1 In the y-direction, the thickness direction is parallel to Figure 1 The z-direction. The first direction is the thickness direction of the cable chain.

[0100] The materials of the first enclosure 1 and the second enclosure 2 are not limited here.

[0101] See Figure 1 The first enclosure 1 and the second enclosure 2 form a continuous sealing structure, preventing debris from directly passing through this continuous sealing structure and entering the protective space 3.

[0102] Cable chains are usually used in combination. Therefore, the sealing ability of a cable chain is mainly judged based on the difficulty of debris entering the protective space 3 through the gap between the first enclosure 1 and the second enclosure 2.

[0103] In some embodiments, holes may be made in the first enclosure 1 and the second enclosure 2 and sealing structures may be provided to seal these holes. This application does not involve this direction, but it is not limited to implementing it in this direction in some practical situations.

[0104] The protective space 3 has two openings along its length, allowing multiple cable chains to be used together, thus improving the ease of cable chain coordination.

[0105] The protective space 3 has a single opening along its length, and this type of cable chain can be installed at the end when multiple cable chains are used together.

[0106] See Figures 1-6 In this embodiment, along the length of the protective space 3, the two end faces of the first enclosure 1 are parallel to the two end faces of the second enclosure 2.

[0107] And / or, along the length of the protective space 3, both end faces of the first enclosure 1 and both end faces of the second enclosure 2 are straight surfaces;

[0108] And / or, along the length of the protective space 3, any adjacent end faces of the first enclosure 1 and the second enclosure 2 are on the same plane.

[0109] Along the length of the protective space 3, the two end faces of the first enclosure 1 and the two end faces of the second enclosure 2 are arranged parallel to each other, as explained below: the four end faces are parallel to each other, which facilitates the use of multiple cable chains and also facilitates the manufacture of cable chains, reducing manufacturing costs.

[0110] Along the length of the protective space 3, both ends of the first enclosure 1 and both ends of the second enclosure 2 are straight surfaces, as explained below: This also facilitates the use of multiple cable chains in conjunction, further reducing the difficulty of manufacturing cable chains.

[0111] Along the length of the protective space 3, any adjacent end faces of the first enclosure 1 and the second enclosure 2 are on the same plane, as explained below: At this time, along the length of the protective space 3, the first enclosure 1 and the second enclosure 2 have the same size, which also facilitates the use of multiple cable chains.

[0112] When the above three methods are used in combination, on the one hand, the processing difficulty of the cable chain can be significantly reduced, thereby reducing costs; on the other hand, the convenience of using the cable chain can be significantly improved; and on the third hand, the sealing performance of the cable chain can also be improved.

[0113] See Figure 2 , Figure 4 and Figure 6 In this embodiment, the mating surfaces of the first enclosure 1 and the second enclosure 2 form multiple continuous sealing interfaces 8.

[0114] In this application, "multiple" refers to at least two.

[0115] Taking two continuous sealing interfaces 8 as an example, along the width direction of the protective space 3 (or the width direction of the cable chain), the two continuous sealing interfaces 8 are located on both sides of the protective space 3 to prevent debris from entering the protective space 3. The sealing interfaces 8 are continuous to improve the sealing performance of the cable chain.

[0116] There may be three or more continuous sealing interfaces 8, some of which may be connected to each other, depending on the shape of the first enclosure 1 and the second enclosure 2.

[0117] In some embodiments, at least a portion of the continuous sealing interface 8 is a stepped surface.

[0118] See Figures 1-4 In this embodiment, the first locking assembly 4 includes a connecting section 41 and a locking section 42 connected to each other, wherein the connecting section 41 is connected to the first enclosure 1;

[0119] In the width direction of the protective space 3, the size of the locking segment 42 is larger than the size of the connecting segment 41;

[0120] The second enclosure 2 is provided with a first groove 51 corresponding to the connecting section 41 and a second groove 52 corresponding to the locking section 42. The first groove 51 and the second groove 52 are connected and constitute the second locking assembly 5.

[0121] The sealed cable chain is in an assembled state:

[0122] In the assembled state, the connecting section 41 and the locking section 42 are positioned one-to-one in the first groove 51 and the second groove 52, respectively, and the locking section 42 and the second groove 52 cooperate to restrict the relative movement of the first enclosure 1 and the second enclosure 2 along the thickness direction of the protective space 3.

[0123] For ease of understanding, the combination of connecting section 41 and locking section 42 can be regarded as a T-shaped locking block, and the combination of first groove 51 and second groove 52 can be regarded as a T-shaped locking groove. When the T-shaped locking block is assembled in the T-shaped locking groove, it can only move along the length of the protective space 3 to separate the two. This can ensure the assembly stability of the first enclosure 1 and the second enclosure 2, and facilitate the quick separation of the first enclosure 1 and the second enclosure 2 when necessary.

[0124] This embodiment clarifies a specific method for locking the first enclosure 1 and the second enclosure 2, thereby improving the stability and sealing of the protective space 3 by stably locking the first enclosure 1 and the second enclosure 2.

[0125] In some embodiments, the first enclosure 1, the connecting section 41, and the locking section 42 are integrally formed to improve the structural strength of the cable chain.

[0126] In some embodiments, along the length of the protective space 3, both the first groove 51 and the second groove 52 are fitted with the second enclosure 2, which reduces the difficulty of groove processing and structural cost.

[0127] In some embodiments, the connecting segment 41 is sized to match the first groove 51 to ensure the assembly stability of the first enclosure 1 and the second enclosure 2.

[0128] In some embodiments, the size of the locking segment 42 is smaller than the size of the second groove 52, so as to reduce the assembly and separation difficulty of the first enclosure 1 and the second enclosure 2.

[0129] For a specific configuration of the connecting section 41, locking section 42, first groove 51, and second groove 52, see [reference needed]. Figures 1-4 .

[0130] See Figures 5-6 In this embodiment, the first enclosure 1 is provided with a third groove 43, and the third groove 43 constitutes the first locking assembly 4;

[0131] A portion of the surface of the second enclosure 2 is provided with protrusions to form a locking protrusion 53 corresponding to the third groove 43, the locking protrusion 53 constituting the second locking fitting 5;

[0132] The sealed cable chain is in an assembled state:

[0133] In the assembled state, along the thickness direction of the protective space 3, the wall of the third groove 43 is attached to the symmetrical two side surfaces of the locking protrusion 53 to restrict the relative movement of the first enclosure 1 and the second enclosure 2 along the thickness direction of the protective space 3.

[0134] The locking protrusion 53 can be regarded as part of the second enclosure 2, or as a structure outside the second enclosure 2.

[0135] For ease of understanding, the third groove 43 is provided with a first sidewall, a second sidewall, and a bottom wall. The first sidewall and the second sidewall are symmetrically arranged in the thickness direction of the protective space 3, and the first sidewall is located above the second sidewall. In the assembled state, both the first sidewall and the second sidewall are in contact with the locking protrusion 53, and the first sidewall restricts the movement of the locking protrusion 53 relative to the third groove 43 along the thickness direction of the protective space 3.

[0136] For a specific configuration of the third groove 43 and the locking protrusion 53, see [reference needed]. Figure 6 .

[0137] This embodiment clarifies another specific method for locking the first enclosure 1 and the second enclosure 2. Similarly, by stably locking the first enclosure 1 and the second enclosure 2, the stability and sealing of the protective space 3 are improved. Both methods can be used selectively to meet different needs.

[0138] In some embodiments, the third trough 43 passes through the first enclosure 1 along the length of the protective space 3, reducing the difficulty of trough processing and structural cost.

[0139] See Figures 1-6 In this embodiment, the first enclosure 1 is provided with a fourth groove 61, and the fourth groove 61 constitutes the first sealing device 6.

[0140] A portion of the surface of the second enclosure 2 is provided with protrusions to form a sealing protrusion 71 corresponding to the fourth groove 61, the sealing protrusion 71 constituting the second sealing assembly 7;

[0141] The sealed cable chain is in an assembled state:

[0142] In the assembled state, the sealing protrusion 71 is fitted to the wall of the fourth groove 61 to form a continuous sealing assembly surface 9.

[0143] This embodiment is used as an example for illustration. Other embodiments can refer to this description. Some contents of this embodiment can be summarized as follows: one of the two enclosures is provided with a fourth groove 61, and the other is formed with a sealing protrusion 71. In this embodiment, the first enclosure 1 and the second enclosure 2 are specified only for the convenience of illustration and understanding.

[0144] The following description will continue using this embodiment as an example. Other embodiments will refer to this description: This embodiment can cover two technical solutions. One is that the first sealing device 6 is only provided on one side of the protective space 3 along its own width direction, which is suitable for situations where it is only necessary to focus on preventing debris from entering the protective space 3 from one side. The other is that the first sealing device 6 is provided on both sides of the protective space 3 along its own width direction.

[0145] Due to limitations in processing difficulty and processing cost, there is a gap between the first enclosure 1 and the second enclosure 2, and the gap between the first locking assembly 4 and the second locking assembly 5 may be even larger, such as when the two are not perfectly matched in size to avoid high assembly difficulty.

[0146] This embodiment clarifies a specific arrangement of the first sealing component 6 and the second sealing component 7. By forming a continuous sealing assembly surface 9, debris is prevented from entering the protective space 3 through the gap between the first enclosure 1 and the second enclosure 2, thus improving the sealing performance of the protective space 3. This makes the cable chain in this application particularly suitable for scenarios with high requirements for sealing and protection capabilities, expanding the applicability of the cable chain. This also reduces the precision requirements for the processing of structures such as the first enclosure 1 and the second enclosure 2, thereby reducing processing costs.

[0147] It should be noted that the second enclosure 2 may have a fourth groove 61, while the first enclosure 1 may have a sealing protrusion 71. Alternatively, one of the first enclosure 1 and the second enclosure 2 may have a fourth groove 61, while the other may have a sealing protrusion 71.

[0148] It should also be noted that this application does not restrict the combination of various specific schemes, and can be selected according to the actual situation.

[0149] See Figure 2 In this embodiment, in the assembled state, the projection of the continuous sealing assembly surface 9 along the length direction of the protective space 3 has at least two intersection points with a vertical plane.

[0150] Vertical plane based on Figure 2 Sure.

[0151] For ease of understanding, the projection of the continuous sealing assembly surface 9 onto the length of the protective space 3 is set to be arc-shaped, with a central angle of 200 degrees (adjustable). See [reference needed]. Figure 2 .

[0152] This embodiment restricts the continuous sealing assembly surface 9. Based on this, the continuous sealing assembly surface 9 itself can restrict the relative movement of the first enclosure 1 and the second enclosure 2 in the thickness direction of the protective space 3, thereby improving the assembly stability of the first enclosure 1 and the second enclosure 2 while ensuring the sealing effect.

[0153] See Figure 4 , Figure 6 In this embodiment, in the width direction of the protective space 3, the first locking device 4 is located between the first sealing device 6 and the protective space 3;

[0154] Alternatively, in the width direction of the protective space 3, the first sealing fitting 6 is located between the first locking fitting 4 and the protective space 3.

[0155] See Figure 4 In the width direction of the protective space 3, the first locking device 4 is located between the first sealing device 6 and the protective space 3, and the second locking device 5 corresponds to the first locking device 4. Therefore, the second locking device 5 is located between the second sealing device 7 and the protective space 3. Based on this, the sealing structure is relatively outward, and the cable chain has stronger sealing performance.

[0156] See Figure 6 In the width direction of the protective space 3, the first sealing component 6 is positioned between the first locking component 4 and the protective space 3. Based on this, more processing requirements can be met, such as adaptive design and processing according to the shapes of the first enclosure 1 and the second enclosure 2.

[0157] See Figures 1-6 In this embodiment, the first locking assembly 4 and the second locking assembly 5 form a locking structure, and there are two locking structures arranged in parallel in the width direction of the protective space 3.

[0158] The first sealing component 6 and the second sealing component 7 form a sealing structure. There are two sealing structures, which are arranged in parallel in the width direction of the protective space 3.

[0159] In this embodiment, a single first sealing component 6 is considered to be located on one side of the protective space 3 along its width direction.

[0160] The following descriptions use locking structures as examples; the sealing structure is described in the same way.

[0161] In some embodiments, two locking structures are provided at one end of the cable chain along the width direction of the protective space 3 to further improve the stability of the cable chain.

[0162] In some embodiments, along the width direction of the protective space 3, two locking structures are respectively disposed at both ends of the cable chain to further improve the sealing and stability of the cable chain; the above embodiments can be regarded as covering the schemes of being disposed at one end of the cable chain and being disposed at both ends of the cable chain, and this part limits this.

[0163] When two locking structures are set in parallel, they can be arranged symmetrically (see [reference]). Figure 6 Alternatively, an asymmetrical setup can be used. In an asymmetrical setup, the two locking structures can overlap by translation. Both setups are suitable for different processing modes, making this application applicable to different processing equipment.

[0164] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
