[0011] This utility model uses a snap-fit ​​part to fix the cable chain structure to the side. The snap-fit ​​part is fixedly connected to the stop part through a connecting part. The snap-fit ​​part has a connecting hole, which is fixedly connected to the connecting frame. Multiple stop bodies are fixedly connected to the connecting frame. In use, the stop part is located on the upper side of the cable chain. When the cable chain is suspended, the middle of the cable chain will tend to drop. The stop structure on the side of the cable chain structure is subjected to force, causing adjacent stop parts to abut against each other for support.

[0019] 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.

[0020] Example 1:

[0021] like Figures 1-5 As shown, this utility model provides a stop structure for a cable chain, including a stop body 1 and a connecting bone 2. The connecting bone 2 is fixedly connected to the stop body 1. The stop body 1 includes a stop portion 3 and a fastening portion 4. The stop portion 3 is fixedly connected to the fastening portion 4 through a connecting portion 5. The fastening portion 4 has a connecting hole 6, which is fixedly connected to the connecting bone 2. Multiple stop bodies 1 are fixedly connected to the connecting bone 2. The fastening portion 4 has an upper clamping arm 7 and a lower clamping arm 8, both of which have fastening protrusions 9. The fastening protrusions 9 are triangular in shape. The connecting bone 2 is made of elastic material, and the connecting bone 2 and the stop body 1 are fixed by secondary injection molding or adhesive bonding.

[0022] A stop structure for a cable chain includes a second stop portion 10 and a second connecting member 11. The second connecting member 11 extends to provide multiple second stop portions 10, and the bottom of the second connecting member 11 extends to provide a connecting post 12, which is provided with a protruding ring 13. The second stop portion 10, the second connecting member 11, and the connecting post 12 are integrally injection molded and are made of an elastic material.

[0023] Through the above technical solution, this utility model is fixed to the side of the cable chain structure by the fastening part 4. The fastening part 4 is fixedly connected to the stop part 3 through the connecting part. The fastening part 4 is provided with a connecting hole 6, which is fixedly connected to the connecting bone 2. Multiple stop bodies 1 are fixedly connected to the connecting bone 2. In use, the stop part 3 is located on the upper side of the cable chain. When the cable chain is suspended, the middle of the cable chain will have a downward tendency. The stop structure on the side of the cable chain structure is subjected to force, so that the adjacent stop parts 3 abut against each other and support each other. With the action of the connecting bone 2, the stop structure is straightened and fixed to form a support frame, which improves the support capacity of the cable chain structure, improves the smoothness of the cable chain structure's rolling process, prevents the cable chain structure from tipping over, and improves the stability of equipment operation.

[0024] The connecting frame 21 of this utility model extends with multiple stop parts 20. A plug-in post 12 extends from the bottom of the connecting frame 21, and the plug-in post 12 has a protruding ring 13. In use, this stop structure is fixed to the cable chain structure. Specifically, the cable chain structure has plug-in holes corresponding to the plug-in posts 12. The plug-in post 12 of the stop structure is inserted into the plug-in hole, and the protruding ring 13 cooperates to fix the stop structure to the cable chain structure. The stop structure is installed on the upper side of the cable chain structure. When the cable chain is suspended, the middle of the cable chain will have a downward tendency, which acts on the stop structure, causing adjacent stop parts 20 to abut and support each other. Combined with the action of the connecting frame 21, the stop structure straightens and is fixed to form a support frame, improving the support capacity of the cable chain structure, improving the smoothness of the cable chain's rolling process, preventing the cable chain structure from tipping over, and improving the stability of equipment operation.

[0025] Example 2:

[0026] like Figures 1-5 As shown, the connecting frame 2 of this utility model is fixedly connected to the stop body 1. The stop body 1 consists of a stop part 3 and a fastening part 4, with the stop part 3 fixedly connected to the fastening part 4 via a connecting part 5. The fastening part 4 has a connecting hole 6, which is fixedly connected to the connecting frame 2. Multiple stop bodies 1 are fixedly connected to the connecting frame 2, forming a continuous support structure. In specific applications, this stop structure is installed on the side of the cable chain. During use, the stop part 3 is located above the cable chain. When the cable chain is suspended, a downward force is generated in the middle of the cable chain, acting on the stop structure. At this time, adjacent stop parts 3 will abut against each other, forming a rigid support frame under the connection of the connecting frame 2. This structural design significantly increases the overall rigidity of the cable chain and effectively reduces the sagging deformation of the cable chain in the suspended state. The connecting frame 2 connects multiple stop bodies 1 in series, making the entire stop structure a continuous support system. When the cable chain is under stress, the connecting rib 2 straightens and fixes itself, further enhancing the support effect. This design not only improves the support capacity of the cable chain but also enhances its rolling performance. The cable chain moves more smoothly and steadily, greatly reducing the risk of tipping over. The stop structure design solves the problem of cable chains sagging in the middle due to their own weight and internal loads when used suspended for long distances. It effectively improves the stability of the cable chain in a suspended state by adding a rigid support frame to the cable chain. This structure is simple and effective, easy to manufacture and install, and suitable for various occasions requiring cable chains to be used suspended for long distances. The stop structure, through the combination of stop body 1 and connecting rib 2, forms a highly efficient support system. It not only enhances the structural strength of the cable chain but also improves its operational stability and reliability. This design is of great significance for improving the overall performance and service life of the cable chain system.

[0027] Example 3:

[0028] like Figures 1-5 As shown, the fastening part 4 of this utility model is provided with an upper clamping arm 7 and a lower clamping arm 8, both of which are provided with fastening protrusions 9. This design enhances the fixing effect between the stop structure and the cable chain. The upper clamping arm 7 and the lower clamping arm 8 form a clamping structure that can tightly clamp the side of the cable chain. The fastening protrusions 9 further increase the clamping firmness. When the stop structure is installed on the cable chain, the upper and lower clamping arms 8 clamp the side of the cable chain in the middle, and the fastening protrusions 9 are embedded in the cable chain structure, forming a stable connection. This clamping structure design allows the stop structure to be firmly fixed to the cable chain, making it difficult to loosen or fall off. During the movement of the cable chain, even if subjected to vibration and impact, the stop structure can remain stable. This is crucial for ensuring the reliability of the entire support system. During installation, simply insert the side of the cable chain between the upper and lower clamping arms 8, and use the elastic deformation of the clamping arms to achieve fixation. This design simplifies the installation process and requires no additional fixing tools or parts. The fastening protrusions 9 further enhance the fixing effect. These components can be embedded in the grooves or holes of the cable chain structure to form a mechanical interlock, preventing the stop structure from sliding or rotating during cable chain movement. This design ensures that the stop structure always remains in the correct position and orientation, achieving optimal support. The fastening part 4 of this invention significantly improves the fixing reliability and ease of use of the stop structure. It not only guarantees the stable performance of the support effect but also simplifies the installation and maintenance process, improving the practicality and economy of the entire system.

[0029] Example 4:

[0030] like Figures 1-5 As shown, the shape of the snap-fit ​​protrusion 9 has been optimized based on Embodiment 3. The snap-fit ​​protrusion 9 is triangular in shape. This design further improves the fixing effect and durability of the snap-fit ​​protrusion 9. The pointed end of the triangle can be easily inserted into the gaps or holes of the cable chain structure, improving the convenience of installation. Furthermore, the triangular shape has good mechanical strength, is not easily deformed or worn, and extends its service life.

[0031] Example 5:

[0032] like Figures 1-5As shown, the connecting member 2 of this utility model is made of elastic material and is fixed to the stop body 1 by a two-stage injection molding or adhesive bonding. This design further optimizes the performance and manufacturing process of the stop structure. In the manufacturing process, the stop body 1, including the stop portion 3, connecting portion 5, and fastening portion 4, is first molded from a rigid material. Then, the stop body 1 is retained in the injection molding machine, and a second injection molding is performed using a mold to directly inject the elastic connecting member 2 onto the stop body 1. This two-stage injection molding process ensures a tight bond between the connecting member 2 and the stop body 1, eliminating the need for additional connection steps. In other embodiments, the connecting member 2 and the stop body 1 are fixed by adhesive bonding, reducing production costs. The elastic connecting member 2 possesses excellent flexibility and elasticity, capable of adapting to various deformations of the cable chain during use. When the cable chain bends, the soft rubber connecting member 2 deforms accordingly. During use, the flexibility of the soft rubber connecting member 2 allows the stop structure to deform with the movement of the cable chain. When the cable chain is folded, the connecting rib 2 can elastically deform without hindering the movement of the cable chain. When the cable chain is unfolded, the connecting rib 2 can quickly return to its original shape, providing necessary support for the cable chain. This dynamic adaptability greatly improves the service life and reliability of the stop structure.

[0033] The connecting part 5 can be set with different heights according to different models of cable chains, and is used to adjust the height of the stop part 3 to match the corrugated tube of the cable chain.

[0034] Example 6:

[0035] like Figures 1-5 As shown, the connecting rib 2 11 of this utility model has multiple stop portions 2 10 extending along its length direction, and these stop portions 2 10 are distributed at equal intervals. Several insertion posts 12 extend from the bottom of the connecting rib 2 11. Each insertion post 12 has a protruding ring 13 located at the center of the insertion post 12. The connecting rib 2 11 is a long strip structure. The insertion posts 12 extend downwards perpendicular to the connecting rib 2 11 to fix the entire stop structure to the cable chain. The diameter of the protruding ring 13 is slightly larger than the diameter of the insertion post 12, forming a ring-shaped protrusion. In use, the stop structure is installed on the upper surface of the cable chain. The insertion posts 12 are inserted into pre-set insertion holes in the cable chain, and the protruding ring 13 is in close contact with the inner wall of the insertion hole, increasing the stability of the fixation. The multiple stop portions 2 10 are arranged along the length direction of the cable chain. When the cable chain bears a load, adjacent stop portions 2 10 will abut against each other for support, forming a series of support points. These support points are connected as a whole by the connecting bone 11, working together to resist the downward tendency of the cable chain. The design of the plug post 12 and the convex ring 13 ensures that the stop structure is firmly fixed to the cable chain, preventing loosening or detachment even under high-speed movement or heavy loads. The presence of the convex ring 13 increases the contact area and friction between the plug post 12 and the plug hole, further improving the reliability of the fixation.

[0036] Example 7:

[0037] like Figures 1-5 As shown, the stop part 2 10, connecting bone 2 11, and insert post 12 of this utility model are manufactured using an integral injection molding process, and the material selected is an elastic material. In the manufacturing process, the mold is designed first. The cavity shape of the mold corresponds to the final shape of the stop structure, including multiple stop parts 2 10, connecting bone 2 11 penetrating the stop parts 2 10, and multiple insert posts 12 extending from the bottom of the connecting bone 2 11. The mold also includes a groove for forming the protruding ring 13. The selected elastic material has appropriate elasticity and toughness, providing a certain degree of deformation capacity while maintaining structural strength. The integral injection molding method makes the entire stop structure a seamless whole, avoiding the seams or connection points that may result from traditional multi-part assembly. This manufacturing method improves the overall strength and durability of the product and reduces potential failure points. The selection of an elastic material gives the stop structure a certain degree of elastic deformation capacity. When the cable chain moves, the stop structure can deform moderately with the bending of the cable chain, but can quickly return to its original shape, continuously providing support. This material property also enhances the wear resistance and impact resistance of the stop structure, extending the product's service life.
