Description

Technical Field

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

[0002] Cable chains are mainly used to secure cables, wires, or compressed air pipes, facilitating their rotation and movement. They can coordinate with the moving parts of machine tools and mechanical equipment, providing safety protection and guidance. The new roller cable chain is an improvement on the traditional cable chain, adding rollers and other components to give it better mobility and wear resistance. It is commonly used in CNC machine tools, electronic equipment, lifting and transportation equipment, and other fields.

[0003] However, when a complete cable chain is in operation, a conventional cable chain needs to slide on the cable chain body in the sliding state. The friction between the cable chain bodies is sliding friction. When the cable chain is very long, the huge friction will limit the length of the cable chain to a very short distance. This not only limits the operating distance and reduces equipment efficiency, but also aggravates wear, generates too much heat and affects performance. Ultimately, the length of the cable chain is limited and cannot meet the needs of long-distance industrial scenarios. To address this, we propose a new type of roller cable chain. Utility Model Content

[0004] The purpose of this invention is to provide a novel roller cable chain to solve the problem mentioned in the background art: when a complete cable chain is running, a conventional cable chain needs to slide on the cable chain body in the sliding state. The friction between the cable chain bodies is sliding friction. When the cable chain is very long, the friction is huge, which limits the length of the cable chain to a very short distance. This not only limits the running distance and reduces equipment efficiency, but also aggravates wear, generates too much heat and affects performance, ultimately resulting in the cable chain length being limited and unable to meet the needs of long-distance industrial scenarios.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel roller cable chain, comprising a cable chain body, wherein a roller side plate assembly is provided inside the cable chain body, the roller side plate assembly can flexibly rotate along the extension direction of the cable chain body to adapt to the bending action of the cable chain, an inner side plate assembly is provided on one side of the roller side plate assembly, the inner side plate assembly is used to connect the roller side plate assemblies on both sides and enhance the overall structural stability of the cable chain, and roller side plate assemblies are provided on both sides of the inner side plate assembly, the roller side plate assemblies on both sides being symmetrically distributed on both sides of the inner side plate assembly, together forming the side support structure of the cable chain.

[0006] The inner side panel assembly includes an inner side panel made of high-strength engineering plastic to combine rigidity and toughness. A limit groove is provided on one side of the inner side panel, and a hinge rod is fixedly installed on one side of the inner side panel. The hinge rod has a cylindrical structure and is set perpendicular to the inner side panel. A second wear-resistant buckle is fixedly installed on the other side of the inner side panel. The second wear-resistant buckle is made of wear-resistant rubber to reduce wear during long-term use.

[0007] The second wear-resistant buckle is snapped onto the top of the second crossbar. The snapping structure between the second wear-resistant buckle and the second crossbar is an interference fit to ensure a stable connection. The inner side plate, the limiting groove, the hinge rod and the second wear-resistant buckle are all symmetrically arranged in twos about the longitudinal central axis of the second crossbar. The second crossbar and the second wear-resistant buckle are also symmetrically arranged in twos about the transverse central axis of the inner side plate.

[0008] The roller side plate assembly includes a hinged cylinder, the inner diameter of which is adapted to the outer diameter of the hinge rod. The inside of the hinged cylinder is hinged to the hinge rod. The hinged cylinder is fixedly installed on one side of the outer side plate. A bullseye ball is fixedly installed on the top of the outer side plate. The bullseye ball can rotate freely.

[0009] A first wear-resistant buckle is fixedly installed on the other side of the outer side plate. The first wear-resistant buckle is made of the same material as the second wear-resistant buckle and has a matching structure. A first crossbar is snapped onto the top of the first wear-resistant buckle. The first crossbar is made of the same material as the second crossbar and has a matching diameter. A limit frame is fixedly installed on one side of the outer side plate. The limit frame has a protruding structure and matches the shape of the limit groove. The inside of the limit groove is slidably connected to the limit frame.

[0010] Among them, the outer side plate, the limiting frame, the bullseye ball, the hinged cylinder and the first wear-resistant buckle are all symmetrically arranged in twos about the longitudinal central axis of the first crossbar. The symmetrical structure ensures the balance performance of the roller side plate assembly. The first crossbar, the bullseye ball and the second wear-resistant buckle are all symmetrically arranged in twos about the transverse central axis of the inner side plate.

[0011] This utility model has at least the following beneficial effects: The bullseye balls at the top of the roller side plate assembly can rotate freely 360 degrees, effectively reducing the frictional resistance between the cable chain and the contacting objects during the movement of the cable chain, significantly improving the smoothness of the cable chain movement, and reducing energy loss. The key components of the inner side plate assembly and roller side plate assembly, such as the inner side plate, limiting groove, hinge rod, second wear-resistant buckle, as well as the outer side plate, limiting frame, and bullseye balls, are all symmetrically arranged about the longitudinal central axis of symmetry of the corresponding crossbar or the transverse central axis of symmetry of the inner side plate. The symmetrical structure ensures that the cable chain is subjected to uniform force during movement and support, improves the overall balance performance, further enhances the stability of the cable chain, and extends its service life.

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.

[0015] Please see Figures 1 to 5 This utility model provides a technical solution: a novel roller cable chain, including a cable chain body 1, a roller side plate assembly 2 is provided inside the cable chain body 1, the roller side plate assembly 2 can rotate flexibly along the extension direction of the cable chain body 1 to adapt to the bending action of the cable chain, an inner side plate assembly 3 is provided on one side of the roller side plate assembly 2, the inner side plate assembly 3 is used to connect the roller side plate assemblies 2 on both sides and enhance the overall structural stability of the cable chain, roller side plate assemblies 2 are provided on both sides of the inner side plate assembly 3, and the roller side plate assemblies 2 on both sides are symmetrically distributed on both sides of the inner side plate assembly 3, together forming the side support structure of the cable chain.

[0016] The inner side panel assembly 3 includes an inner side panel 33, which is made of high-strength engineering plastic to combine rigidity and toughness. A limiting groove 32 is provided on one side of the inner side panel 33. A hinge rod 31 is fixedly installed on one side of the inner side panel 33. The hinge rod 31 has a cylindrical structure and is perpendicular to the inner side panel 33. A second wear-resistant buckle 34 is fixedly installed on the other side of the inner side panel 33. The second wear-resistant buckle 34 is made of wear-resistant rubber to reduce wear during long-term use. A second crossbar 35 is engaged with the top of the second wear-resistant buckle 34. The engagement structure between the second wear-resistant buckle 34 and the second crossbar 35 is an interference fit to ensure a stable connection. The limiting groove 32, the hinge rod 31, and the second wear-resistant buckle 34 are all symmetrically arranged in twos about the longitudinal central axis of the second crossbar 35. The second crossbar 35 and the second wear-resistant buckle 34 are also symmetrically arranged in twos about the transverse central axis of the inner side plate 33. The hinge rods 31 on both sides of the inner side plate 33 are hinged to the hinge cylinder 26 of the roller side plate assembly 2, realizing the movable connection with the roller side plate assembly 2 on both sides, providing basic structural support for the entire cable chain. At the same time, the second wear-resistant buckle 34 and the second crossbar 35 are connected by an interference fit, and the wear-resistant rubber material reduces wear during long-term use. The symmetrically distributed structure ensures the stability of the connection and the overall balance.

[0017] The roller side plate assembly 2 includes a hinged cylinder 26, the inner diameter of which is adapted to the outer diameter of the hinge rod 31. The hinged cylinder 26 is hinged to the hinge rod 31. The hinged cylinder 26 is fixedly installed on one side of the outer side plate 21. A bullseye ball bearing 22 is fixedly installed on the top of the outer side plate 21. The bullseye ball bearing 22 can rotate freely 360 degrees. The bullseye ball bearing 22 forms rolling friction with the contact surface through its spherical structure, which significantly reduces the coefficient of sliding friction, thereby reducing the rolling friction. Dynamic resistance; a first wear-resistant buckle 23 is fixedly installed on the other side of the outer side plate 21. The material of the first wear-resistant buckle 23 is the same as that of the second wear-resistant buckle 34 and the structure is compatible. The top of the first wear-resistant buckle 23 is engaged with a first crossbar 24. The first crossbar 24 and the second crossbar 35 are made of the same material and the diameter is compatible. A limit frame 25 is fixedly installed on one side of the outer side plate 21. The limit frame 25 is a protruding structure and matches the shape of the limit groove 32. The limit groove 32... The inner side plate 21 is slidably connected to the limiting frame 25. The outer side plate 21, the limiting frame 25, the bullseye ball bearing 22, the hinged cylinder 26, and the first wear-resistant buckle 23 are all symmetrically arranged in twos about the longitudinal central axis of the first crossbar 24. The symmetrical structure makes the roller side plate assembly 2 evenly distributed when under force, reducing wear caused by off-center load, thereby improving balance performance. The first crossbar 24, the bullseye ball bearing 22, and the second wear-resistant buckle 34 are all symmetrically arranged in twos about the transverse central axis of the inner side plate 33. The hinged cylinder 26 on the outer side plate 21 is hinged to the hinged rod 31 of the inner side plate assembly 3, realizing the movable connection with the inner side plate assembly 3, so that the roller side plate assembly 2 can rotate flexibly along the extension direction of the cable chain to adapt to the bending action of the cable chain. At the same time, the limiting frame 25 on the outer side plate 21 is slidably connected to the limiting groove 32 of the inner side plate assembly 3. During the rotation, the matching structure of the limiting frame 25 and the limiting groove 32 limits the rotation amplitude and ensures the stability of the action.

[0018] When the cable chain needs to bend, the roller side plate assembly 2 can rotate flexibly along the extension direction of the cable chain body 1 to adapt. Since the inner diameter of the hinged cylinder 26 in the roller side plate assembly 2 matches the outer diameter of the hinged rod 31 in the inner side plate assembly 3, they form a hinge, providing a basis for rotation. Simultaneously, the limiting bracket 25 on the roller side plate assembly 2 is a protruding structure that matches the shape of the upper limiting groove 32 in the inner side plate assembly 3 and slides within it. This fit ensures rotational flexibility while limiting the rotation range. To ensure structural stability, the inner side plate 33, made of high-strength engineering plastic, combines rigidity and toughness, providing reliable support for the overall structure. The bullseye ball bearings 22 at the top of the roller side plate assembly 2 can rotate freely 360 degrees, effectively reducing frictional resistance during the cable chain's movement and improving smoothness. Regarding connections, the second wear-resistant buckle 34 and the second crossbar 35 in the inner side plate assembly 3 have an interference fit, while the first wear-resistant buckle 23 in the roller side plate assembly 2... The first wear-resistant buckle 23 and the second wear-resistant buckle 34 are made of the same material and have a compatible structure. The first crossbar 24 and the second crossbar 35 are made of the same material and have a compatible diameter. These designs ensure the stability of the connection between the components. At the same time, the inner side plate 33, the limiting groove 32, the hinge rod 31 and the second wear-resistant buckle 34 are symmetrically arranged in twos about the longitudinal center axis of the second crossbar 35. The outer side plate 21, the limiting frame 25, the bullseye ball 22, the hinge cylinder 26 and the first wear-resistant buckle 23 are all about the longitudinal center axis of the second crossbar 35. Two crossbars 24 are symmetrically arranged about the longitudinal central axis of symmetry. The first crossbar 24, the bullseye ball 22, and the second wear-resistant buckle 34 are also symmetrically arranged about the transverse central axis of symmetry of the inner side plate 33. The symmetrical structure ensures the balance performance of the roller side plate assembly 2 and the entire cable chain, ensuring that the cable chain is subjected to uniform force during movement and support, further improving the stability and service life of the cable chain. In addition, the second wear-resistant buckle 34 is made of wear-resistant rubber material, which can reduce wear during long-term use and extend the replacement cycle of the parts.
