[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1:

[0022] like Figures 1-6 As shown, the present invention provides a fixing structure for a cable chain, including a housing 1, which is composed of two half-shells 2 that are closed and fixed together. Each half-shell 2 has a fixing rib 3. A pressure wire structure 4 is fixedly installed on the housing 1. The pressure wire structure 4 has fixing holes 5 and includes a first pressure plate 6 and a second pressure plate 7. The first pressure plate 6 is fixedly connected to the second pressure plate 7 via a connector 8. The other end of the first pressure plate 6 has a first fastening part 9, and the other end of the second pressure plate 7 has a first hook 10. The first fastening part 9 and the first hook 10 are engaged and fixed. The first pressure plate 6 and the second pressure plate 7 are fixedly secured by bolts 11. A hole diameter adjustment block 12 is fixedly installed in the fixing holes 5. Each half-shell 2 has a support rod 13, with a protrusion 14 at its end. Each half-shell 2 has a second hook 15 and a second fastening part 16. Each half-shell 2 has an accessory assembly part 17.

[0023] Through the above technical solution, the housing 1 of this utility model is composed of two half-shells 2 that are covered and fixed together. The half-shell 2 is provided with fixing ribs 3, which are used to fix the corrugated tube of the cable chain. The fixing ribs 3 are fitted and fixed with the corrugations of the cable chain corrugated tube. The housing 1 is fixedly installed with a wire pressing structure 4. The wire pressing structure 4 is provided with fixing holes 5. The wire pressing structure 4 includes a first pressure plate 6 and a second pressure plate 7. The first pressure plate 6 is fixedly connected to the second pressure plate 7 through a connector 8. The first pressure plate 6 and the second pressure plate 7 are snapped together and fixed by a snap-fit ​​structure. In use, the pressure plates of the wire pressing structure 4 are opened, and the cable is placed into the fixing hole 5. The first pressure plate 6 and the second pressure plate 7 are pressed together to fix the cable. The cable chain and the wire pressing structure 4 are then installed in the half-shell 2. The corrugations of the cable chain corrugated tube are fixed in conjunction with the fixing ribs 3. Then the other half-shell 2 is closed to complete the assembly. Through this utility model, the cable is fixed at both ends of the cable chain. The wire pressing structure 4 fixes the cable, reducing cable friction loss and noise, and extending the cable life.

[0024] Example 2:

[0025] like Figures 1-6 As shown, the housing 1 of this utility model consists of two half-shells 2, which are connected and fixed together by bolts 11 or snap-fit. Several parallel fixing ribs 3 are arranged transversely along the length of the inner surface of the half-shells 2, and the cross-sectional shape of the fixing ribs 3 matches the corrugated shape of the cable chain corrugated pipe. The wire clamping structure 4 is fixedly installed inside the housing 1 by snap-fit ​​or screws. The wire clamping structure 4 has multiple circular fixing holes 5, the diameter of which is slightly larger than the outer diameter of the cable.

[0026] The first pressure plate 6 and the second pressure plate 7 of the wire clamping structure 4 are made of plastic or metal. One end of the first pressure plate 6 is connected to one end of the second pressure plate 7 via a connector 8, which is a flexible strap or a hinge structure, allowing the first pressure plate 6 to rotate and open relative to the second pressure plate 7. The other end of the first pressure plate 6 is provided with a first fastening part 9, and the other end of the second pressure plate 7 is provided with a barbed first hook 10. When the first pressure plate 6 rotates to the closed position, the first fastening part 9 and the first hook 10 form a stable locking engagement. When the wire clamping structure 4 is in the closed state, a complete fixing hole 5 is formed between the first pressure plate 6 and the second pressure plate 7, and the cable is securely clamped within the fixing hole 5.

[0027] In actual use, the operator first opens the pressure plate, exposing the semi-circular groove of the fixing hole 5 on the other pressure plate. The cable to be fixed is placed into the semi-circular groove of the fixing hole 5, and then the first pressure plate 6 is rotated to close, causing the first fastening part 9 to automatically engage and lock with the first hook 10. At this time, the cable is completely enclosed within the fixing hole 5 formed by the first pressure plate 6 and the second pressure plate 7, achieving a reliable fixing effect. After the cable is fixed, the entire cable clamping structure 4 is installed in the predetermined position of one of the half-shells 2 using screws. Then, the end of the cable chain corrugated pipe is fitted and fixed with the fixing rib 3 inside the half-shell 2. Finally, the other half-shell 2 is closed and the fastening bolts 11 are tightened, completing the assembly of the entire fixing structure.

[0028] The fixing structure of this embodiment demonstrates excellent performance in practical applications. The wire clamping structure 4 effectively holds cables of different diameters, preventing them from swaying and rubbing during cable chain movement. The split design of the housing 1 facilitates installation and maintenance, and the cooperation between the fixing rib 3 and the corrugated pipe ensures the reliability of the cable chain connection. The snap-fit ​​design between the first fastening part 9 and the first hook 10 makes the opening and closing operation of the wire clamping structure 4 simple and quick, greatly improving installation efficiency. The entire fixing structure maintains stable performance during long-term use, effectively extending the service life of the cables and reducing equipment maintenance costs.

[0029] Example 3:

[0030] like Figures 1-6 As shown, the first pressure plate 6 and the second pressure plate 7 of this utility model are fixedly connected by bolts 11. In this embodiment, the first pressure plate 6 and the second pressure plate 7 are initially fixed by the engagement of the first fastening part 9 and the first hook 10, and then the bolts 11 are tightened to further increase the clamping force. This double fixing method ensures that the cable in the fixing hole 5 can be firmly clamped, effectively preventing the cable from shaking or shifting during the movement of the cable chain.

[0031] In the specific implementation process, one end of the first pressure plate 6 is provided with a first fastening part 9, and the corresponding end of the second pressure plate 7 is provided with a first hook 10. When it is necessary to fix the cable, the operator places the cable in the fixing hole 5, and then aligns and engages the first fastening part 9 of the first pressure plate 6 with the first hook 10 of the second pressure plate 7 to achieve initial fixation. At this time, the cable has been initially clamped in the fixing hole 5, but in order to ensure the firmness of the clamping, it is necessary to further tighten the first pressure plate 6 and the second pressure plate 7 with bolts 11.

[0032] The bolt 11 is installed at the same end of the first pressure plate 6 and the second pressure plate 7, that is, at the same end as the snap-fit ​​structure, and is used with the connector 8 to press and fix the first pressure plate 6 and the second pressure plate 7. The bolt 11 passes through the through holes on the first pressure plate 6 and the second pressure plate 7 and is tightened by the nut. As the bolt 11 is tightened, the clamping force between the first pressure plate 6 and the second pressure plate 7 gradually increases, so that the cable in the fixing hole 5 is firmly clamped. This design not only improves the reliability of cable fixing, but also makes it easy for operators to adjust the clamping force according to actual needs.

[0033] The advantage of this embodiment lies in the dual cooperation of the snap-fit ​​structure and the bolt 11, which ensures both ease of installation and secure cable fixation. The snap-fit ​​structure enables quick initial fixation, while the bolt 11 provides adjustable clamping force to accommodate cables of different diameters.

[0034] In practical applications, this embodiment is particularly suitable for cable chain systems that require frequent reciprocating motion. Because the cables are securely fixed in the clamping structure 4, even during frequent cable chain movement, the cables will not experience significant shaking or friction, thereby reducing noise and improving equipment stability. At the same time, this fixing structure design facilitates cable maintenance and replacement; operators only need to loosen bolt 11 to open the clamping structure 4 without disassembling the entire cable chain system.

[0035] Example 4:

[0036] like Figures 1-6 As shown, the fixing hole 5 of this utility model is fixedly installed with a hole diameter adjustment block 12. The housing 1 is assembled from two symmetrical half-shells 2 by a cover-and-fitting method. The half-shell 2 has a fixing rib 3 structure for fixing the cable chain corrugated pipe inside. The pressure wire structure 4 is installed in the housing 1 through a connector 8. The pressure wire structure 4 consists of a first pressure plate 6 and a second pressure plate 7. The two are connected by the connector 8 to achieve an openable and closable connection. The end of the first pressure plate 6 is provided with a fastening part, and the second pressure plate 7 is provided with a hook structure at the corresponding position. When the pressure wire structure 4 is closed, the fastening part and the hook engage with each other to achieve locking.

[0037] A detachable aperture adjustment block 12 is installed in the fixing hole 5 of the wire clamping structure 4. This aperture adjustment block 12 is made of elastic or rigid material and can adapt to the fixing requirements of cables of different diameters. The aperture adjustment allows for the setting of different diameters and numbers of holes to accommodate different specifications of cables, such as signal lines and control lines. When fixing a single cable, the hole position closest to the cable diameter can be selected; when fixing multiple cables simultaneously, different combinations of hole positions can be selected based on the cable diameters.

[0038] The aperture adjustment block 12 is installed with the fixing hole 5 using an interference fit, ensuring that it will not shift or fall off during use. The outer edge of the aperture adjustment block 12 has an annular protrusion that forms a locking structure with the groove on the inner wall of the fixing hole 5, further enhancing the stability of the connection. When it is necessary to replace the aperture adjustment block 12, it can be easily removed from the fixing hole 5 by applying appropriate external force. The aperture adjustment block 12 adopts a split design, and 1-4 aperture adjustment blocks 12 can be installed according to actual usage needs. Each aperture adjustment block 12 can be installed or removed independently, allowing for flexible adjustment of the number of cables fixed.

[0039] During use, first select a suitable aperture adjustment block 12 configuration based on the number and diameter of the cables. Press the selected aperture adjustment block 12 into the fixing hole 5, ensuring proper installation. Open the wire clamping structure 4, and thread the cables sequentially into the corresponding holes of the aperture adjustment block 12. Then close the wire clamping structure 4 to lock the fastener and hook. Finally, install the assembled wire clamping structure 4 into the half-shell 2, and cover and fix it with the other half-shell 2 to complete the assembly of the entire fixing structure. Through the multi-hole design of the aperture adjustment block 12, stable fixing of cables of different specifications is achieved, effectively reducing the shaking and friction of the cables during the movement of the cable chain.

[0040] Example 5:

[0041] like Figures 1-6 As shown, the half-shell 2 of this utility model is provided with a support rod 13, and the end of the support rod 13 is provided with a protrusion 14. The support rod 13 is located outside the half-shell 2, which facilitates the fixing of cables with cable ties and realizes the cable management outside the shell 1.

[0042] In this embodiment, a support rod 13 is provided on the outside of the half-shell 2, extending outward from the surface of the half-shell 2 to form a support structure for fixing cables. The end of the support rod 13 has a protrusion 14, which prevents cable ties from slipping when fixing cables, improving the stability of cable fixing. The number of support rods 13 can be set according to actual needs; for example, multiple support rods 13 can be provided on one side of the shell 1 to accommodate different numbers of cables.

[0043] The structural design of the support rod 13 enables it to withstand the tension of the cable ties, ensuring that the cable will not loosen during the movement of the cable chain. The protrusion 14 of the support rod 13 can be spherical, cylindrical, or other shapes, as long as it can limit the displacement of the cable ties. The connection between the support rod 13 and the half-shell 2 can be integrally molded or fixed separately, ensuring that the strength of the support rod 13 meets the usage requirements.

[0044] In practical applications, when cables within the cable chain need to be secured, operators can fix the cables to the support rod 13 and use cable ties to secure them. Because the support rod 13 has a protrusion 14 at its end, the cable ties will not easily slip off during securing, thus ensuring the cable's secureness. Furthermore, the support rod 13 makes the cable routing neater, preventing cables from being scattered haphazardly outside the cable chain and reducing mutual interference and friction between cables.

[0045] The fixing structure of this embodiment is suitable for cable chain systems in various industrial automation equipment, effectively improving the fixing reliability of cables and reducing cable wear caused by vibration or movement. Meanwhile, the design of the support rod 13 simplifies the cable management process, facilitating maintenance and repair.

[0046] In a further embodiment, the support rods 13 are distributed circumferentially along the half-shell 2 to accommodate cable fixing requirements in different directions. For example, at the bends in the cable chain, the support rods 13 can be positioned on the outer side of the bend to provide better cable support. Furthermore, the length and angle of the support rods 13 can be adjusted according to the actual application scenario to ensure that the cable fixing does not affect the normal movement of the cable chain.

[0047] Example 6:

[0048] like Figures 1-6 As shown, the housing 1 of this invention consists of two identical half-shells 2, each half-shell 2 having a second hook 15 and a second fastening part 16. During assembly, the second hook 15 of the first half-shell 2 engages with the second fastening part 16 of the second half-shell 2, and simultaneously, the second fastening part 16 of the first half-shell 2 engages with the second hook 15 of the second half-shell 2, thus forming a stable housing 1 structure. This symmetrical design of the half-shells 2 allows the two half-shells 2 to be completely interchangeable without needing to distinguish between left and right or up and down directions, greatly simplifying the assembly process.

[0049] In this embodiment, the two half-shells 2 adopt identical structural designs and are fixed by the mutual cooperation of the second hook 15 and the second fastening part 16. When assembling the shell 1, the operator only needs to place any two half-shells 2 opposite each other, align the second hook 15 of one half-shell 2 with the second fastening part 16 of the other half-shell 2, and apply appropriate pressure to complete the snap-fit ​​fixation. Since the two half-shells 2 have the same structure, there is no need to consider orientation during assembly, effectively avoiding assembly problems caused by incorrect orientation.

[0050] This symmetrical half-shell design offers significant advantages in manufacturing. Since both half-shells are produced using the same mold, manufacturers only need to develop one set of molds to meet production requirements, avoiding the need for two separate symmetrical molds as in traditional designs. This not only reduces mold development costs but also simplifies production management and improves efficiency. Furthermore, the identical half-shell structure reduces error rates during production, as operators do not need to distinguish between different types of half-shell components.

[0051] In practical applications, this symmetrically designed fixing structure exhibits excellent stability and reliability. The cooperative design of the second hook 15 and the second fastening part 16 ensures that the housing 1 remains firmly connected even when subjected to external forces, effectively preventing accidental detachment. When it is necessary to disassemble the housing 1 for maintenance or replacement of parts, the two half-shells 2 can be separated simply by applying an appropriate separating force, making the operation quick and easy.

[0052] Example 7:

[0053] like Figures 1-6 As shown, the accessory assembly part 17 on the half-shell 2 of this utility model consists of multiple evenly distributed rectangular grooves. These grooves are arranged parallel to each other along the length of the half-shell 2, and the inner wall of the grooves is provided with guide protrusions. When it is necessary to install the built-in keel, the connecting end of the keel can slide into the groove along the guide protrusion and be fixedly connected by locking screws or buckles. This design makes the keel installation process more convenient and ensures the connection stability between the keel and the half-shell 2.

[0054] Another embodiment of the accessory assembly 17 features an annular boss structure on the inner side of the half-shell 2, with a threaded hole at its center. When a sensor or other detection device needs to be installed, the device base can be aligned with the boss and secured with bolts 11. The outer periphery of the annular boss also has an anti-rotation groove to prevent relative rotation of the installed device. This structure is particularly suitable for accessory components requiring precise installation, improving installation accuracy and reliability.

[0055] For applications requiring frequent accessory replacement, the accessory assembly section 17 is designed with a magnetic quick-release structure. A strong magnet array is embedded on the surface of the half-shell 2, and a magnetic guide plate is installed at the corresponding position on the bottom of the accessory. Magnetic attraction enables quick installation and fixation, while mechanical positioning pins ensure installation accuracy. This design maintains ease of assembly and disassembly while meeting the required fixation strength under normal operating conditions.

[0056] The accessory assembly section 17 also integrates electrical connection functions, with conductive wiring pre-embedded inside the half-shell 2 and standardized electrical interfaces provided at the assembly section location. When installing intelligent accessories that require power, power and signal transmission channels can be directly obtained through the interfaces without additional wiring. This integrated design significantly simplifies the installation process of intelligent accessories and improves system integration.

[0057] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
