DETAILED DESCRIPTION

[0022] 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.

[0023] Example 1:

[0024] like Figures 1-8 As shown, this utility model provides an easy-to-assemble and disassemble cable chain, including a corrugated tube assembly 1. The corrugated tube assembly 1 is composed of a first assembly 2 and a second assembly 3. The first assembly 2 has a first half-tube 4, and the second assembly 3 has a second half-tube 5. The first half-tube 4 and the second half-tube 5 are closed to form a corrugated tube 6. The first assembly 2 is fixedly connected to the second assembly 3 through a hinge part 7. The first half-tube 4 has a plug block 8, which is fixedly connected to a fixing member 10 through a plug hole 9. The fixing member 10 has a partition arm 11. The partition arm 11 has a pin block 12. The fixing member 10 has a plug part 13, which is plugged into and fixed to the plug hole 9. The plug part 13 has a protrusion 14, and the plug hole 9 has a recess 15. The protrusion 14 and the recess 15 are engaged and fixed. The hinge part 7 has elastic deformation capability. The corrugated tube assembly 1 is provided with a zipper lock clip 16.

[0025] Through the above technical solution, the corrugated pipe assembly 1 of this utility model is composed of a first assembly 2 and a second assembly 3. The first assembly 2 is provided with a first half-pipe 4, and the second assembly 3 is provided with a second half-pipe 5. The first assembly 2 is fixedly connected to the first assembly 2 through a hinge part 137. The first half-pipe 4 is provided with a plug block 8. The plug block 8 is fixedly connected to a fixing member 10 through a plug hole 9. The fixing member 10 is used to put the cable inside the first half-pipe 4 to prevent the cable from coming out. When it is necessary to install or replace the cable, the first assembly 2 and the second assembly 3 are opened to separate the first half-pipe 4 and the second half-pipe 5. The fixing member 10 is removed, the cable is installed or replaced, and then the fixing member 10 is installed back. The fixing member 10 puts the cable inside the first half-pipe 4, and then the first assembly 2 and the second assembly 3 are closed and fixed, so as to quickly complete the installation and replacement of the cable in the corrugated pipe 6.

[0026] Example 2:

[0027] like Figures 1-8 As shown, the corrugated pipe assembly 1 of this utility model consists of a first assembly 2 and a second assembly 3. The first assembly 2 has a first half-pipe 4, and the second assembly 3 has a second half-pipe 5. The first half-pipe 4 and the second half-pipe 5 are closed to form a complete corrugated pipe 6 structure. The second assembly 3 is fixedly connected to the first assembly 2 through a hinge 7, so that the corrugated pipe assembly 1 can be opened and closed like a book. The first half-pipe 4 has a plug block 8, and the plug block 8 is fixedly connected to the fixing member 10 through a plug hole 9.

[0028] The inner walls of the first half pipe 4 and the second half pipe 5 are provided with corrugated structures, which increase the flexibility and pressure resistance of the corrugated pipe 6. In addition, the outer surfaces of the first joint 2 and the second joint 3 are provided with anti-slip textures, which improve the holding feeling and operation stability of the operator.

[0029] The hinge part 7 is integrally formed with the first joint 2 and the second joint 3. One end of the hinge is fixed on the first joint 2, and the other end is fixed on the second joint 3. The design of the hinge part 7 allows the first joint 2 and the second joint 3 to be freely opened and closed, which facilitates the installation and replacement of cables by the operator.

[0030] The plug-in block 8 is located on both inner sides of the first half pipe 4 and has a cylindrical shape. The plug-in block 8 is integrally formed with the first half pipe 4, ensuring the structural integrity and strength. The plug-in block 8 is provided with a plug-in hole 9, which is plugged and fixed with a fixing part 10.

[0031] The shape of the fixing part 10 is designed to match the internal contour of the second half pipe 5, ensuring that the fixing part 10 cuts into the corrugated part of the second half pipe 5 after installation. The surface of the fixing part 10 is smooth, avoiding damage to the cable.

[0032] In use, the operator first opens the corrugated pipe set 1, separates the first half pipe 4 and the second half pipe 5. Then remove the fixing part 10, put the cable to be installed or replaced into the first half pipe 4. Then reinstall the fixing part 10, insert the plug-in block 8 into the plug-in hole 9 to fix the position of the cable. Finally, close the corrugated pipe set 1 to complete the installation process.

[0033] This design not only solves the problem that the traditional corrugated pipe 6 is easy to scatter when installing or replacing the cable, but also significantly improves the convenience and efficiency of operation. The use of the fixing part 10 ensures that the cable remains fixed and orderly in the corrugated pipe 6, reducing the risk of cable entanglement and damage. At the same time, the design of the hinge structure makes the opening and closing of the corrugated pipe 6 simple and fast, greatly shortening the installation and maintenance time.

[0034] Example Three:

[0035] As shown in FIG- Figure 8As shown, based on embodiment two, the fixing member 10 is provided with partition arms 11. The partition arms 11 are mainly used to clamp the supporting keels, and can also separate the cables. The main body of the fixing member 10 is in the shape of a cuboid, which is adapted to the internal shape of the corrugated pipe 6. The two sides of the fixing member 10 are provided with plug-in parts 13 matched with the plug-in blocks 8, which are used to connect and fix with the first half pipe 4. The partition arms 11 are in the shape of thin plates. The number of the partition arms 11 can be set according to actual needs, and generally, the interval is 20-40 cm. The height of each partition arm 11 is slightly lower than the inner diameter of the corrugated pipe 6, so as to ensure that it does not affect the closure of the corrugated pipe 6. The material of the partition arms 11 is the same as that of the main body of the fixing member 10, which ensures the consistency and strength of the structure. One of the main functions of the partition arms 11 is to clamp the supporting keels. The keel is a supporting structure used to enhance the carrying capacity of the corrugated pipe 6. The partition arms 11 are provided with grooves matched with the shape of the keel, which can firmly fix the keel and prevent the keel from shifting or shaking during use. This design enhances the stability and carrying capacity of the entire corrugated pipe 6 structure. Another important function is to separate the cables. The partition arms 11 divide the internal space of the corrugated pipe 6 into multiple independent areas, and each area can accommodate different types or functions of cables. This separation design effectively prevents mutual interference and entanglement between different cables, improves the management efficiency and safety of the cables. At the same time, the separation structure also facilitates the identification and tracking of different cables, simplifying the maintenance and replacement process.

[0036] The surface of the partition arm 11 has a smooth surface, which reduces friction with the cable and prevents the cable from being scratched or worn. The edges of the partition arm 11 are chamfered, further reducing potential damage to the cable. In use, the operator first installs the keel in the groove of the partition arm 11. Then, according to the type and number of different cables, the cables are placed in different areas divided by the partition arm 11. This method not only makes the arrangement of the cables more orderly, but also improves the utilization rate of the internal space of the corrugated pipe 6.

[0037] The partition arm 11 of the utility model is provided with a latch block 12, which is inserted into the corrugation of the corrugated pipe 6, improving the assembly stability of the fixing member 10. The latch block 12 is arranged at the bottom of the partition arm 11, and the width of the latch block 12 is slightly smaller than the width of the corrugated groove of the corrugated pipe 6, and the height is equivalent to the corrugated depth. The material of the latch block 12 is the same as that of the partition arm 11, which ensures the consistency and strength of the structure. The surface of the latch block 12 is smooth, and the edges are chamfered to avoid damage to the corrugated pipe 6 during insertion and removal. The main function of the latch block 12 is to improve the assembly stability of the fixing member 10. When the fixing member 10 is installed into the corrugated pipe 6, the latch block 12 will automatically insert into the corrugated groove of the corrugated pipe 6. This mechanical engagement not only increases the stability of the fixing member 10, but also prevents the fixing member 10 from shifting or shaking during use.

[0038] Embodiment four:

[0039] AsFigures 1-8 As shown, the fixing member 10 of this utility model has a plug-in portion 13, which is plugged into and fixed to the plug-in hole 9, thus fixing the fixing member 10 to the first half-tube 4. The plug-in portion 13 is designed to match the shape of the plug-in hole 9, and is cylindrical. The diameter or side length of the plug-in portion 13 is slightly smaller than the inner diameter or inner side length of the plug-in hole 9 to ensure an appropriate gap during insertion. The length of the plug-in portion 13 is designed to be able to be fully inserted into the plug-in hole 9 and remain stable after insertion. The end of the plug-in portion 13 can be designed with a slightly chamfered shape to facilitate insertion into the plug-in hole 9. A reinforcing rib is provided between the main body of the fixing member 10 and the plug-in portion 13 to enhance the connection strength. The inner wall of the plug-in hole 9 is designed with small protrusions or grooves, which cooperate with the plug-in portion 13 to form a snap-fit ​​structure, increasing the stability of the connection. The plug-in fixing method makes the fixing member 10 and the first half-tube 4 detachable, which facilitates future maintenance and replacement. This connection method requires no additional tools, is simple and quick to operate, and is suitable for applications that require frequent disassembly and assembly.

[0040] Example 5:

[0041] like Figures 1-8 As shown, the insertion part 13 of this utility model has a protrusion 14, and the insertion hole 9 has a recess 15. The protrusion 14 and the recess 15 are snapped together and fixed, further improving the firmness of the connection between the fixing member 10 and the first half-tube 4. The protrusion 14 is designed as a circular protrusion or a square protrusion, located on the side or end of the insertion part 13. The height of the protrusion 14 is slightly less than the depth of the recess 15 to ensure that the overall structure is not affected when snapped together. The recess 15 is designed as a groove that matches the shape of the protrusion 14, located on the inner wall or bottom of the insertion hole 9. The edge of the protrusion 14 is designed with a smooth transition to avoid stress concentration. The edge of the recess 15 is also rounded to facilitate the smooth entry of the protrusion 14. The elastic design of the snap-fit ​​fixation allows the protrusion 14 to detach from the recess 15 under a certain external force, facilitating disassembly. This snap-fit ​​fixation design increases the stability of the connection between the fixing member 10 and the first half-tube 4 and reduces the risk of loosening due to vibration or external force. Meanwhile, the snap-fit ​​structure provides clear feedback on whether the assembly is in place, allowing the operator to clearly perceive whether the connection is complete.

[0042] Example 6:

[0043] like Figures 1-8As shown, the hinge portion 7 of this invention has elastic deformation capability. The cross-section of the hinge portion 7 is designed as a thin-walled structure with uniform thickness to ensure uniform stress distribution during deformation. The length of the hinge portion 7 is determined according to the dimensions of the first assembly 2 and the second assembly 3 to ensure that the opening and closing angle meets the usage requirements. The hinge portion 7 is integrally formed with the first assembly 2 and the second assembly 3. A small groove is designed on the center line of the hinge portion 7 to increase the controllability of elastic deformation. The elastic deformation capability of the hinge portion 7 allows the bellows assembly 1 to adapt to different opening and closing angles, increasing the flexibility of use. At the same time, the elastic design also enhances the durability of the hinge portion 7 and reduces the risk of fatigue failure caused by repeated opening and closing.

[0044] Example 7:

[0045] like Figures 1-8 As shown, the corrugated pipe assembly 1 of this utility model is equipped with a zipper clip 16, which facilitates quick and easy engagement and fixation of the first assembly 2 and the second assembly 3. The zipper clip 16 has a groove with a flared end. The internal contour of the groove matches the shape of the engagement parts of the first assembly 2 and the second assembly 3, ensuring stability during engagement. The flared opening angle facilitates guiding the engagement parts into the groove. The outer surface of the zipper clip 16 has an anti-slip texture to increase grip comfort during operation. One end of the zipper clip 16 has a handle for easy user operation.
