Description

Technical Field

[0001] This utility model belongs to the technical field of cable guide components, specifically relating to an angle-adjustable chain-link cable guide. Background Technology

[0002] With the rapid development of industrial automation and intelligent manufacturing, the application of high-end equipment such as robotic arms, automated production lines, and intelligent warehousing equipment is becoming increasingly widespread. During operation, such equipment often exhibits multi-degree-of-freedom and highly dynamic motion characteristics. The safe guidance and protection of the power cables and signal cables required by the equipment have become key aspects to ensure the stable operation of the equipment. As the core component for cable protection and guidance, the performance requirements of cable guides are constantly increasing. Therefore, it is necessary to design an angle-adjustable link-type cable guide.

[0003] Existing cable guides generally have cable protection defects: First, there are guides without isolation structures, where multiple cables are directly run through the same channel. When the equipment moves, the cables are prone to friction and entanglement, and long-term use leads to wear on the cable sheath, causing short circuits or signal interference. Second, there are simple support guides. Although there is a basic separation structure, the support components are mostly fixed by welding or bonding. After assembly, they cannot be adapted to the angle adjustment of the guide. When the angle changes, the support components are prone to falling off, losing their isolation and protection function. Utility Model Content

[0004] The purpose of this invention is to provide a simple and reasonably designed adjustable-angle chain cable guide in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions: An angle-adjustable link-type cable guide includes a cable guide component comprising multiple segments. The segments are internally connected to an internal connector. The inner sides of each cable guide component are internally connected to a support / isolation component that mates with the internal connector. Each support / isolation component includes multiple connectors integrally injection-molded with the inner sides of the segments. The inner sides of each connector are internally connected to a support component that mates with the internal connector. Each support component has multiple protruding engagement parts integrally injection-molded on the side closest to the segment, which engage with the interior of the connector.

[0006] As a further optimization of this utility model, the segment includes an integrally injection-molded inner connecting part and an outer connecting part. The inner connecting part is inserted into the inner side of the outer connecting part. A storage part is provided on one side of the inner connecting part, and a buckle part is integrally injection-molded on the other side of the inner connecting part. The buckle part is placed inside the storage part and cooperates with it.

[0007] As a further optimization of this utility model, the multiple connectors can be integrally injection molded on the inner side of the inner connection part, and multiple engaging grooves are provided on the side of the multiple connectors that are close to each other.

[0008] As a further optimization of this utility model, the internal connector includes a main frame located at the middle position inside multiple segments, and multiple webs are integrally injection molded on the outside of the multiple main frames. A connector bracket that engages with the buckle portion is integrally injection molded on the side of the multiple webs that is far apart from each other.

[0009] As a further optimization of this utility model, the main frame has multiple locking blocks integrally injection molded on the side away from the web plate, and the sides of the multiple supporting members that are close to each other are integrally injection molded with grooved engaging members, and the multiple grooved engaging members are engaged and connected to the outside of the multiple locking blocks.

[0010] As a further optimization of this utility model, the main frame is integrally injection molded with a ball joint ball, and the ball joint ball has a limiting groove on its outside.

[0011] As a further optimization of this utility model, the other side of the main frame is integrally injection molded with a ball joint socket. The ball joint socket is engaged with and cooperates with the ball of the ball joint. The top and bottom of the ball joint socket are integrally injection molded with limiting blocks. The limiting blocks are engaged with and cooperate with the inner side of the limiting groove.

[0012] As a further optimization of this utility model, the ball and socket of the ball-and-socket joint adopt a standardized disk-solid ball pair modular topology. A single disk serves as the basic topological carrier, and the outer ring of the spokes of the disk and the solid ball pair form a composite topological unit. The solid ball pair serves as the core connection node, so that when the structure is under load, the load is transmitted radially to the outer ring through the spokes, and then the multi-directional force flow is redistributed through the spatial spherical contact of the ball pair.

[0013] As a further optimization of this utility model, the ball and socket joint ball and socket joint socket are stacked to form a chain-type multi-rigid-flexible coupling system with gap ball pair, and the ball structure of the ball is a locally flexible body.

[0014] The beneficial effects of this utility model are as follows: The support and isolation component of this utility model achieves stable isolation and protection through "multi-dimensional locking and fixing". On the one hand, the connector is integrally injection molded into the inner side of the inner connecting part of the cable guide. The support component is tightly fixed with the locking groove of the connector through the protruding locking component. At the same time, the locking component of the groove of the support component is locked with the locking block of the main frame of the internal connector for a second time, forming "double fixing". Even if the guide angle is frequently adjusted, the support component will not shift or fall off. On the other hand, the support component can divide the internal space of the guide into multiple independent channels, through which multiple cables are run, completely avoiding mutual friction and entanglement. At the same time, it can also facilitate the differentiation and placement of different cables, making it easy for operators to quickly find and repair them later.

[0015] This utility model achieves three-dimensional multi-angle adjustment through the cooperative structure of "ball socket connector ball + ball socket connector socket": the main frame of adjacent internal connecting parts can rotate flexibly around the center of the ball through the ball socket, covering the multi-directional angle adjustment needs required for equipment movement. At the same time, the limiting groove of the ball socket connector ball and the limiting block of the ball socket connector socket precisely engage, which can strictly limit the adjustment angle range and avoid excessive rotation causing cable pulling.

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1 like Figure 1 , Figure 2 , Figure 3 As shown, the angle-adjustable chain-link cable guide includes a cable guide 1, a support and isolation component 2, and an internal connector 3. The cable guide 1 is the outer frame of the guide and is used to wrap the cable. The support and isolation component 2 is assembled inside the cable guide 1 and serves to support and isolate the cable. The internal connector 3 runs through multiple cable guides 1, realizing the connection and angle adjustment of multiple guide sections. The three components work together to form a complete chain-link cable guide structure, which can be flexibly bent or straightened according to the movement trajectory of the equipment.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 6 As shown, the cable guide 1 is composed of multiple segments 100 spliced ​​together (in this embodiment, there are three segments 100, and the specific number can be increased and assembled by the operator according to the actual operation requirements). Each segment 100 is manufactured by an integral injection molding process. Its structure includes two core parts: an inner connecting part 101 and an outer connecting part 104. Adjacent segments 100 are connected by the inner connecting part 101 and the outer connecting part 104. The inner connecting part 101 of the previous segment 100 can be inserted into the inner side of the outer connecting part 104 of the next segment 100 to form a nested splicing structure, which provides a basis for the length extension and angle adjustment of the guide.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 6 As shown, the snap-fit ​​positioning of segment 100 has a storage part 103 on one side of the inner connecting part 101, and a snap-fit ​​part 102 integrally injection molded on the other side. When adjacent segments 100 are inserted, the snap-fit ​​part 102 of the previous segment 100 can be embedded into the storage part 103 of the next segment 100 and fit tightly, realizing the initial positioning of the segments 100 after splicing, preventing the splice from loosening, and at the same time not affecting the relative rotation during subsequent angle adjustment.

[0022] like Figure 1 , Figure 2 , Figure 7 , Figure 8As shown, the support isolation component 2 is assembled inside the cable guide component 1 and cooperates with the internal connector 3 to realize the support and isolation of the cable. It consists of multiple connectors 200, support component 202 and protruding locking component 203. The multiple connectors 200 are directly formed inside the inner connecting part 101 of the cable guide component 1 by integral injection molding process. That is, each segment 100 has a connector 200 fixed on the inner wall of the inner connecting part 101. Multiple locking grooves are opened on the side of the adjacent connectors 200 that are close to each other for cooperation with the protruding locking component 203 of the support component 202.

[0023] like Figure 1 , Figure 2 , Figure 7 , Figure 8 As shown, the engagement of the support member 202 and the connector 200 is as follows: The support member 202 provides direct support for the cable. On the side near segment 100, multiple protruding engagement parts 203 are integrally injection molded. During assembly, the support member 202 is placed between two adjacent connectors 200, so that the protruding engagement parts 203 are correspondingly embedded in the engagement grooves of the connectors 200, thereby achieving the engagement and fixation of the support member 202 and the connectors 200. This allows the support member 202 to be stably assembled inside the cable guide 1. The protruding engagement parts 203 have integrally injection molded hidden buckles (not shown in the figure), while the inner side of the engagement groove of the connector 200 has a hidden groove (not shown in the figure). The engagement of the hidden buckles and the hidden groove further improves the firmness of the engagement between the connector 200 and the protruding engagement parts 203.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the internal connector 3 is the "skeleton" of the guide, running through multiple cable guides 1 to achieve the connection and angle adjustment of multiple guide sections. It consists of a main frame 304, a web plate 300, a connector bracket 301, a locking block 201, a ball socket connector ball 302, a ball socket connector socket 305, and a limiting block 306. The main frame 304 is located in the middle of the inner side of multiple segments 100. Multiple web plates 300 are integrally injection molded on its exterior (the number of web plates 300 is the same as that of segments 100, used to fix and support the segments when they are combined). The web plates 300 are radially distributed along the main frame 304. On the side of the web plates 300 that are far apart, a connector bracket 301 is integrally injection molded. The connector bracket 301 engages with the locking part 102 of the segment 100 - that is, the locking part 102 is inserted into the slot of the connector bracket 301, realizing the fixed connection between the main frame 304 and the segment 100, and ensuring that the cable guide 1 and the internal connector 3 move synchronously.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the connection between the main frame 304 and the support member 202 is as follows: On the side of the main frame 304 away from the web plate 300, multiple locking blocks 201 are integrally injection molded. Correspondingly, on the side of the support member 202 close to it, a grooved locking member 204 is integrally injection molded. During assembly, the grooved locking member 204 of the support member 202 is engaged and connected to the outside of the locking blocks 201 of the main frame 304, so that the support member 202 and the main frame 304 are fixed together, further enhancing the stability of the support isolation member 2 and preventing the support member 202 from shifting due to cable compression.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the angle adjustment structure is designed as follows: To achieve adjustable guide angle, a ball joint sphere 302 is integrally injection molded at one end of the main frame 304. A limiting groove 303 is formed on the outside of the ball joint sphere 302. At the other end of the main frame 304, a ball joint socket 305 is integrally injection molded. The shape of the ball joint socket 305 matches that of the ball joint sphere 302, and it can engage with the outside of the ball joint sphere 302 of the adjacent main frame 304, forming a ball-socket mating structure. A standardized disk-solid sphere pair modular topology is adopted. A single disk serves as the basic topological carrier. The spokes-outer ring of the disk and the solid sphere pair constitute a composite topological unit. The solid sphere pair serves as the core connection node, allowing the load to be transmitted radially through the spokes when the structure is under load. To the outer ring, the spherical contact of the ball joint achieves multi-directional force redistribution, improving the spatial force transmission efficiency by approximately 25% compared to traditional planar connections. The solid ball joint and the cavity form a gap-contact composite constraint pair between the parts. Under no load or small load conditions, the ball joint maintains a small gap (designed gap 0.1–0.3 mm) with the inner wall of the cavity, granting the structure initial flexible degrees of freedom, allowing for small-angle rotation (θmax1, approximately -10°–10°) and tilting (αmax1, approximately 0°–15°) around the sphere's center. When the load increases or precise constraint is required, the contact between the ball joint and the inner wall of the cavity transforms into contact constraint, utilizing the Hertzian contact mechanics of spherical contact to disperse concentrated loads into surface loads. The contact stress is determined by the Hertzian contact formula: Where F is the contact force, R1 and R2 are the radii of curvature of the contact spheres, v1 and v2 are Poisson's ratios, and E1 and E2 are the elastic moduli. The gap and multiple degrees of freedom of the ball joints provide mechanical redundancy for the cable chain. When a ball joint fails due to fatigue or overload, the adjacent ball joints compensate for the load through degrees of freedom, avoiding instantaneous failure of the cable chain. Through fault tree analysis (FTA) in reliability engineering, the system reliability Rsys of this structure is improved by about 60% compared with rigid connection cable chains without redundancy. By utilizing the gap damping effect of the ball joints, the vibration energy of the system is attenuated by the lubricating medium or structural damping in the gap, improving the vibration resistance of the cable chain. The natural frequency and damping ratio of the cable chain are optimized through complex modal analysis to avoid resonance with the operating frequency of the equipment.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, angle limiting and stabilization: Limiting blocks 306 are integrally injection molded at the top and bottom of the ball socket 305. When the ball socket 305 engages with the ball 302, the limiting blocks 306 precisely engage with the limiting groove 303 inside the ball 302 and fit tightly. This structure allows the ball 302 to rotate around its center within the ball socket 305 to adjust its angle, while the cooperation of the limiting blocks 306 and the limiting groove 303 limits the rotation angle range, preventing excessive rotation that could lead to cable pulling or structural damage. It is suitable for highly dynamic, multi-degree-of-freedom equipment movements, ensuring the safety and precise tracking of cables / pipelines; it meets the requirements of long-stroke, lightweight design, reducing equipment load and improving energy efficiency through mechanical optimization; it is suitable for high-end equipment manufacturing and intelligent logistics scenarios, conforming to the modern mechanical system's trend towards lightweight, highly flexible, and highly reliable design.

[0028] It should be noted that when this angle-adjustable link cable guide is in operation, the cable passes through the internal space enclosed by the cable guide 1 and the support isolation member 2. The support member 202 separates multiple cables to prevent them from rubbing against each other or getting tangled, and facilitates the classification and storage of cables, making it easier for staff to quickly operate and maintain them later. Cables of the same type can be passed through the same layer of space. When the equipment moves, such as a robotic arm, the ball joint ball 302 and the ball joint socket 305 of the adjacent internal connector 3 rotate relative to each other, causing the segment 100 of the cable guide 1 to bend synchronously, thereby realizing the angle adjustment of the guide to match the movement trajectory of the equipment. At the same time, the cooperation between the buckle part 102 and the storage part 103, and the limit block 306 and the limit groove 303, ensures the structural stability during the adjustment process and eliminates the risk of loosening or excessive deformation.

[0029] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
