Description

Technical Field

[0001] This application relates to the field of cable restraint device technology, and in particular to a sliding cable support. Background Technology

[0002] In fields such as heavy machinery, automated equipment, and large instruments, a typical structure often exists: a fixed base and a rotating component that can reciprocate at a large angle around an axis. Cables required for power, control, and signal transmission must pass through the fixed base into the rotating component. Because cylindrical functional compartments or other obstructions are usually arranged on both sides of the shaft system, the cables can only be laid through narrow cable routing holes between these compartments and the rotating ring.

[0003] In existing technologies, cables are commonly restrained using rigid fixing or simple bundling. While this method is suitable for static conditions, it introduces three interconnected and serious problems when rotating components undergo reciprocating motion:

[0004] Cable wear problem: The cable bundle inside the fixed base is forcibly dragged and violently swung by the rotating parts, inevitably causing continuous collisions and friction with the surrounding obstacle structure, which can easily lead to damage to the cable sheath and internal wire core, and thus cause faults such as short circuits and signal interruptions.

[0005] Cable mechanical fatigue damage: The rotational motion of rotating components essentially changes their relative position to the fixed base, directly causing dynamic changes in the effective length required by the cable. Fixed laying methods cannot adapt to this change, causing the cable to be excessively stretched and pulled due to insufficient length at times, and unnaturally bent due to excess length at other times. Under long-term reciprocating action, the cable is highly susceptible to fatigue fracture.

[0006] Disorganized cable arrangement and maintenance difficulties: The disorderly swinging makes the cable arrangement messy, which not only affects the aesthetics and tidiness of the equipment, but also brings great inconvenience to daily inspection, maintenance and even troubleshooting.

[0007] Therefore, there is an urgent need in this field for a dynamic cable management solution that can not only effectively constrain and guide the cable, but more importantly, actively adapt to changes in cable length and posture during movement, thereby fundamentally overcoming the aforementioned deficiencies. Summary of the Invention

[0008] The purpose of this invention is to provide a sliding cable bracket that solves the technical problem in the prior art that the length and orientation of the cable between the fixed base and the rotating component cannot automatically adapt to the rotation of the rotating component.

[0009] The technical solution is as follows:

[0010] A sliding cable support for supporting and guiding a cable between a fixed base and a rotating component having relative rotational motion, comprising: a support rail configured to be fixedly mounted on the fixed base; a sliding component slidably disposed on the support rail; and a cable restraint device rotatably mounted on the sliding component; wherein the sliding component is configured to slide axially along the support rail in response to rotational motion of the rotating component to compensate for changes in cable length; and the cable restraint device is configured to deflect relative to the sliding component in response to changes in cable attitude to adapt to cable torsion.

[0011] Optionally, the cable restraint device and the sliding component are rotatably connected by a cooperating rotating shaft and a shaft hole; the rotating shaft is disposed on one of the cable restraint device and the sliding component, and the shaft hole is correspondingly disposed on the other of the cable restraint device and the sliding component.

[0012] Optionally, the rotating shaft is a rotating column located in the middle of the back side of the cable restraint device, and the shaft hole is located on the sliding component.

[0013] Optionally, the cable restraint device includes a first cable rack and a second cable rack, the first cable rack and the second cable rack being detachably connected to form a closed channel for accommodating the cable.

[0014] Optionally, both the first cable rack and the second cable rack are cable racks with U-shaped grooves, and the two are fastened to each other by a tenon and mortise structure on the mating surface.

[0015] Optionally, an auxiliary column is also provided on the back side of the cable restraint device; an arc-shaped slot is provided on the sliding component; the auxiliary column is housed in the arc-shaped slot, and its sliding trajectory is an arc centered on the axis of the rotating column.

[0016] Optionally, the rotating column and / or the auxiliary column are two-stage shaft structures, with their first-stage shoulder abutting against the inner surface of the sliding component to achieve axial positioning.

[0017] Optionally, the support guide rail includes two parallel guide rods, which are either straight or parallel arcs, and their two ends are integrally connected by limiting cylinders to limit the sliding stroke of the sliding component.

[0018] Optionally, the sliding component includes a front mounting plate, a baffle, and a rear mounting plate; the front mounting plate has a front boss on its front side and a rear boss on its back side; the baffle is mounted to the end face of the front boss by fasteners, and together with the front boss and the front mounting plate, forms a sliding groove that cooperates with the guide rod; the rear mounting plate is mounted to the end face of the rear boss by fasteners, and forms a cavity between the rear mounting plate and the front mounting plate for accommodating the cable restraint device.

[0019] Optionally, the top and / or bottom of the front mounting plate extends to form a first guide bend for guiding and supporting the cable, and the top and / or bottom of the rear mounting plate extends to form a second guide bend for guiding and supporting the cable.

[0020] The beneficial effects of the technical solutions provided in this application include at least the following:

[0021] A sliding cable support is provided for supporting and guiding cables between a fixed base and a rotating component with relative rotational motion. The support includes a support rail, a sliding component, and a cable restraint device. The support rail serves as a fixed reference and is connected to the fixed base by bolts or welding, providing a stable sliding track for the sliding component. The sliding component and the support rail are fitted with a clearance fit. When the rotating component rotates, the axial force generated by the cable being dragged causes the sliding component to slide along the support rail. When the rotating component rotates at a higher angle, requiring a longer cable laying path, the sliding component slides closer to the rotating component to compensate for the cable length gap and prevent cable slack. The cable restraint device is connected to the sliding component via a rotating structure. When the cable twists due to the rotation of the rotating component, the restraint device deflects synchronously with the cable's posture, converting the torsional stress into a smooth rotational displacement and preventing the cable from being forcibly twisted. The beneficial effects of the sliding cable bracket of this application are as follows: the sliding compensation structure can avoid the tension and pulling of the cable due to changes in cable length, and reduce mechanical fatigue; the adaptive deflection can eliminate the torsional stress of the cable and avoid damage to the internal core of the cable caused by hard torsion; the cable restraint device can regulate and accommodate the cable, prevent the cable from swinging disorderly, and thus reduce the collision and wear between the cable and the surrounding structure.

Detailed Implementation

[0039] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0040] In this disclosure, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the relative positions of the corresponding components in the direction of gravity when they are in use, and "inner" and "outer" refer to their relative positions to the contours of the corresponding components themselves. Furthermore, the terms "first," "second," etc., used in this disclosure are for distinguishing one element from another and do not have sequential or importance implications. In the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements.

[0041] refer to Figure 1 and Figure 2 A sliding cable support for supporting and guiding a cable 3 between a fixed base 1 and a rotating component 2 having relative rotational motion, comprising a support rail 4, a sliding component 5, and a cable restraint device 6.

[0042] refer to Figure 3 and Figure 4 The support rail 4 is configured to be fixedly installed on the fixed base 1; the sliding component 5 is slidably disposed on the support rail 4.

[0043] refer to Figure 5 and Figure 6 ,as well as Figure 12 and Figure 13 The cable restraint device 6 is rotatably mounted on the sliding member 5; wherein the sliding member 5 is configured to slide axially along the support rail 4 in response to the rotational movement of the rotating member 2 to compensate for changes in the length of the cable 3; the cable restraint device 6 is configured to deflect relative to the sliding member 5 in response to changes in the attitude of the cable 3 to adapt to the torsion of the cable 3.

[0044] In this embodiment, the support guide rail 4 serves as a fixed reference and is connected to the fixed base 1 by bolts or welding, providing a stable sliding track for the sliding component 5. The sliding component 5 and the support guide rail 4 are fitted with a clearance. When the rotating component 2 rotates, the axial force generated by the cable 3 being dragged will cause the sliding component 5 to slide along the support guide rail 4. For example, when the rotating component 2 rotates at a high angle, the cable 3 needs a longer laying path, and the sliding component 5 slides towards the rotating component 2 to compensate for the length gap of the cable 3 and prevent the cable 3 from being taut. The cable restraint device 6 is connected to the sliding component 5 through a rotating structure. When the cable 3 is twisted due to the rotation of the rotating component 2, the restraint device will deflect synchronously with the attitude of the cable 3, converting the torsional stress into a smooth rotational displacement and preventing the cable 3 from being rigidly twisted.

[0045] The beneficial effects of the technical solution in this embodiment are as follows: Through the dual dynamic adaptive design, the three major defects of the prior art can be solved at once: sliding compensation avoids the tension and pulling of the cable 3 caused by the change in length, reducing mechanical fatigue; adaptive deflection eliminates torsional stress, avoiding damage to the internal core of the cable 3 caused by hard torsion; at the same time, the cable constraint device 6 neatly accommodates the cable 3, preventing the cable 3 from swinging disorderly, reducing collision and wear with the surrounding structure, and the arrangement is neat and easy to maintain.

[0046] Based on the technical solution of this embodiment, refer to Figures 3 to 11 The cable restraint device 6 and the sliding component 5 are rotatably connected by a rotating shaft 7 and a shaft hole 8 that cooperate with each other; the rotating shaft 7 is disposed on one of the two, and the shaft hole 8 is disposed on the other.

[0047] The clearance fit between the rotating shaft 7 and the shaft hole 8 is a mature rotating structure in the mechanical field. Its advantages are: first, it has a compact structure and occupies little space, making it suitable for the narrow installation environment between the fixed base 1 and the rotating component 2; second, it has low rotational resistance, and smooth rotation without jamming can be achieved by controlling the fit clearance between the shaft and the hole; third, it is easy to manufacture, as the rotating shaft 7 can be formed by turning, and the shaft hole 8 can be machined by drilling or boring, making the cost controllable. In specific installation, the rotating shaft 7 can be set on the back side of the cable restraint device 6, and the shaft hole 8 can be opened at the corresponding position of the sliding component 5, or vice versa, the rotating shaft 7 can be set on the sliding component 5, and the shaft hole 8 can be opened in the cable restraint device 6. Both methods can achieve the rotation function, and the choice can be made flexibly according to the installation space.

[0048] The technical solution of this embodiment has the following beneficial effects: compared with complex rotating structures such as hinges and bearings, the matching method between the rotating shaft 7 and the shaft hole 8 is lower in cost and easier to assemble; at the same time, the clearance fit can further reduce the rotational resistance by applying grease, ensuring that it can still maintain stable deflection after long-term use and avoiding damage to the cable 3 caused by rotation jamming.

[0049] In addition to through holes, shaft holes 8 can also be blind holes. For example, a blind hole with a depth greater than the length of the rotating shaft 7 can be opened on the sliding component 5 to prevent the rotating shaft 7 from passing through the other end of the shaft hole 8 and save installation space.

[0050] Based on the technical solution of this embodiment, refer to Figures 8 to 11 The rotating shaft 7 is a rotating column located in the middle of the back side of the cable restraint device 6, and the shaft hole 8 is located on the sliding component 5.

[0051] The rotating column in the middle of the back side ensures the rotational balance of the cable restraint device 6. Its central position ensures that the distance from each point on the cable restraint device 6 to the rotating axis 7 is approximately equal, resulting in uniform force distribution during deflection and eliminating the risk of tilting. The rotating column's placement on the back side avoids encroaching on the cable 3's storage space and prevents compression of the cable 3's laying space, ensuring smooth passage of the cable 3 through the restraint device. The diameter of the rotating column is designed according to the dimensions of the cable restraint device 6, and its length is slightly less than the thickness of the sliding component 5, ensuring no interference with other components during rotation.

[0052] The technical solution of this embodiment has the following beneficial effects: the central rotating column design makes the deflection of the cable restraint device 6 more stable, avoiding uneven force on the cable 3 caused by eccentricity; the back side layout maximizes the use of space, ensuring the integrity of the cable 3 laying channel, while the rotating column has high structural strength and can withstand the torque generated by the dragging of the cable 3, avoiding bending or breakage after long-term use.

[0053] Based on the technical solution of this embodiment, refer to Figure 11 The cable restraint device 6 includes a first cable rack 601 and a second cable rack 602, which are detachably connected to form a closed channel for accommodating the cable 3.

[0054] When the cable 3 is long or pre-connected to equipment, threading the cable is extremely difficult if the cable restraint device 6 is a single structure. The detachable first cable tray 601 and second cable tray 602 structure solves this problem: during installation, the first cable tray 601 and second cable tray 602 are separated, and the cable 3 is placed directly into the groove of one of the components of the first cable tray 601 or second cable tray 602. The two components are then connected and fixed to form a closed channel, eliminating the need for threading. During maintenance, the detachable first cable tray 601 and second cable tray 602 can be quickly opened for easy inspection of the cable 3's condition or replacement of damaged cables. The cross-sectional shape of the closed channel can be designed according to the number of cables 3, such as a circular, rectangular, or U-shaped closed structure, ensuring that the cable 3 will not detach from the restraint device.

[0055] The technical solution of this embodiment has the following beneficial effects: the detachable design greatly reduces the difficulty of assembling and disassembling the cable 3, and is especially suitable for the later maintenance of the cable 3 of the pre-installed equipment; the closed channel provides more reliable constraint on the cable 3, and compared with the open channel, it can prevent the cable 3 from coming out of the constraint device during sliding or deflection, reducing additional wear; at the same time, the two-part structure makes it easy to adjust the channel size according to the diameter of the cable 3, and is suitable for cables of different specifications.

[0056] Based on the technical solution of this embodiment, refer to Figure 11 The first cable rack 601 and the second cable rack 602 are both cable racks with U-shaped grooves, and the two are fastened to each other by mortise and tenon structures on the mating surfaces.

[0057] This embodiment further optimizes the structural details: First, both the first cable rack 601 and the second cable rack 602 are designed with U-shaped grooves. The arc-shaped inner wall of the U-shaped groove fits the cylindrical shape of the cable 3, allowing multiple cables 3 to be accommodated simultaneously and providing circumferential constraint to the cables 3, preventing them from swaying within the groove. Second, a mortise and tenon structure is used for fastening. On the mating surfaces of the two cable racks, one has a tenon (such as a rectangular protrusion), and the other has a corresponding groove (such as a rectangular groove). The gap between the tenon and the groove ensures precise fastening, and no additional fasteners 505 are required. During assembly, the tenon is simply inserted into the groove to complete the fixation, and during disassembly, it can be separated by applying force in the opposite direction. For example, one cable rack has two symmetrical tenons on its mating surface, and the other cable rack has two corresponding grooves on its mating surface. After fastening, a complete rectangular closed channel is formed to accommodate the cable bundle.

[0058] The technical solution of this embodiment has the following beneficial effects: the U-shaped groove structure of the cable rack can improve the fit between the cable 3 and the constraint device, reduce the shaking of the cable 3 during movement, and further reduce wear; the tenon and mortise fastening method does not require additional fasteners 505, avoiding the risk of fasteners 505 being lost, and the assembly efficiency is extremely high, especially suitable for rapid operation in confined spaces; at the same time, the tenon and mortise structure has high positioning accuracy, and the U-shaped grooves of the two cable racks can be precisely aligned after fastening, avoiding the squeezing of the cable 3 due to misalignment.

[0059] In addition to using a smooth metal surface, the inner wall of the U-shaped groove can also be fitted with a self-lubricating pad. This reduces friction and wear, and protects the outer sheath of the cable 3, preventing the metal groove from scratching the cable 3. In addition to using rectangular tenons and rectangular grooves, the mortise and tenon structure can also use trapezoidal tenons and trapezoidal grooves to further improve the reliability of the connection.

[0060] Based on the technical solution of this embodiment, refer to Figures 8 to 11The cable restraint device 6 is also provided with an auxiliary column 603 on its back side; the sliding component 5 is provided with an arc-shaped slot 501; the auxiliary column 603 is housed in the arc-shaped slot 501, and its sliding trajectory is an arc with the axis of the rotating column as the center.

[0061] When the cable restraint device 6 deflects, it may wobble and deflect, causing interference between the cable 3 and the fixed base 1. Therefore, a limiting structure for the cable restraint device 6 needs to be added. Specifically, the auxiliary column 603 is arranged parallel to the rotating column and located on the back side of the cable restraint device 6. The arc-shaped slot 501 on the sliding component 5 is centered on the axis of the rotating column, and its curvature is designed according to the maximum rotation angle of the rotating component 2 (e.g., if the maximum pitch angle of the rotating component is ±30°, then the curvature of the arc-shaped slot 501 is set to 60°). When the cable restraint device 6 deflects, the auxiliary column 603 will slide along the arc-shaped slot 501, and the sliding trajectory is completely consistent with the deflection trajectory of the cable restraint device 6. When the cable restraint device 6 deflects to the maximum angle, the auxiliary column 603 will contact the end of the arc-shaped slot 501 and be blocked from sliding further, thereby limiting the maximum deflection angle of the cable restraint device 6 and avoiding excessive deflection.

[0062] The technical solution of this embodiment has the following beneficial effects: the cooperation between the auxiliary column 603 and the arc-shaped slot 501 achieves the deflection angle limit to prevent the cable 3 from being damaged due to excessive twisting; secondly, it enhances the rotational stability of the cable restraint device 6 and avoids swaying or deflection when supported only by the rotating column; at the same time, the arc-shaped slot 501 can guide the sliding of the auxiliary column 603 to ensure that the cable restraint device 6 always deflects around the rotating column and will not deviate.

[0063] In addition to being a through hole, the arc-shaped slot 501 can also be a semi-open groove, such as an arc-shaped groove on the surface of the sliding component 5, into which the auxiliary column 603 is partially embedded.

[0064] Based on the technical solution of this embodiment, refer to Figure 11 The rotating column and / or the auxiliary column 603 are two-stage shaft structures, and their first-stage shoulder is used to abut against the inner surface of the sliding component 5 to achieve axial positioning.

[0065] When the rotating column and auxiliary column 603 slide within the shaft hole 8 or arc-shaped slot 501 of the sliding component 5, axial movement may occur if there is a lack of axial positioning, leading to failure of the rotating structure. Therefore, it is designed as a two-stage shaft structure: the two-stage shaft consists of two shaft sections with different diameters. The diameter of the first-stage shaft section is smaller than that of the second-stage shaft section, and a shoulder is formed at the connection of the two shaft sections. During assembly, the first-stage shaft section passes through the shaft hole 8 or arc-shaped slot 501 of the sliding component 5, while the second-stage shaft section remains on the side of the cable restraint device 6. The shoulder abuts tightly against the inner surface of the sliding component 5, forming an axial barrier to prevent the rotating column or auxiliary column 603 from moving outwards from the sliding component 5. At the same time, the end face of the shoulder can form a surface contact with the surface of the sliding component 5, reducing local pressure and preventing wear on the surface of the sliding component 5.

[0066] The technical solution of this embodiment has the following beneficial effects: the second-order shaft structure achieves reliable axial positioning through the shaft shoulder, completely solves the problem of component movement, and ensures the long-term stability of the rotating structure; the surface contact design of the shaft shoulder reduces the pressure on the surface of the sliding component 5 and extends its service life; at the same time, the second-order shaft structure is simple to process and can be formed by turning without the need for additional positioning parts, thus simplifying the structure.

[0067] Based on the technical solution of this embodiment, refer to Figure 7 The support rail 4 includes two parallel guide rods 401. The guide rods 401 are straight or parallel arcs, and their two ends are integrally connected by limiting cylinders 402 to limit the sliding stroke of the sliding component 5.

[0068] When the sliding component 5 slides along the support guide rail 4, it is necessary to ensure smooth sliding and prevent derailment. Therefore, a double guide rod 401 design is adopted: two guide rods 401 are set in parallel, and the spacing is designed according to the size of the sliding component 5. The sliding component 5 cooperates with both guide rods 401 to form two-point support, avoiding tilting or jamming of the sliding component 5 caused by a single guide rod 401. The shape of the guide rod 401 is selected according to the relative position of the fixed base 1 and the rotating component 2. If the cable 3 is laid in a straight line between the two, a straight guide rod 401 is used; if the laying path is curved, parallel arc-shaped guide rods 401 are used to ensure that the sliding direction of the sliding component 5 is consistent with the laying direction of the cable 3. At the same time, limiting cylinders 402 are set at both ends of the guide rods 401. The diameter of the limiting cylinders 402 is larger than the diameter of the guide rods 401. When the sliding component 5 slides to the end of the guide rod 401, it will be blocked by the limiting cylinders 402 and cannot continue to slide, thereby limiting the sliding stroke and preventing the sliding component 5 from falling off the guide rods 401.

[0069] The technical solution of this embodiment has the following beneficial effects: the double guide rod 401 design greatly improves the sliding stability of the sliding component 5, reduces the risk of jamming, and ensures the timeliness of cable 3 length compensation; the arc-shaped guide rod 401 expands the applicable scenarios of the bracket and can adapt to complex internal spaces of equipment; the limiting cylinder 402 has a simple structure and high reliability, and does not require additional limit switches or baffles 503, reducing costs, while avoiding cable 3 pulling damage caused by derailment of the sliding component 5.

[0070] In addition to being integrally formed, the limiting cylinder 402 and the guide rod 401 can also be fixed by welding, which makes it easy to adjust the position of the limiting cylinder 402 according to actual needs.

[0071] Based on the technical solution of this embodiment, refer to Figure 6 , Figure 8 , Figure 9 and Figure 10 The sliding component 5 includes a front mounting plate 502, a baffle 503, and a rear mounting plate 504. The front mounting plate 502 has a front boss 5021 on its front side and a rear boss 5022 on its back side. The baffle 503 is mounted on the end face of the front boss 5021 by fasteners 505, and together with the front boss 5021 and the front mounting plate 502, forms a sliding groove that cooperates with the guide rod 401. The rear mounting plate 504 is mounted on the end face of the rear boss 5022 by fasteners 505, and forms a cavity between the rear mounting plate 504 and the front mounting plate 502 for accommodating the cable restraint device 6.

[0072] The sliding component 5 needs to simultaneously fulfill two functions: "sliding engagement with the guide rod 401" and "accommodating the cable restraint device 6." Therefore, it is designed as a combined structure of "front mounting plate - baffle - rear mounting plate": the front mounting plate 502 is the core load-bearing component, and the front boss 5021 on the front is machined with an arc surface that matches the curvature of the guide rod 401. The baffle 503 is fixed to the end face of the front boss 5021 by fasteners 505. The arc surface and the inner surface of the baffle 503 together form a "U-shaped sliding groove." The width of the "U-shaped sliding groove" is... The diameter is slightly larger than that of the guide rod 401 to ensure that the guide rod 401 can slide smoothly; the rear boss 5022 on the back of the front mounting plate 502 is used to connect the rear mounting plate 504. The rear mounting plate 504 is fixed to the end face of the rear boss 5022 by fasteners 505. The gap between the front mounting plate 502 and the rear mounting plate 504 forms a cavity. The size of the cavity is designed according to the volume of the cable restraint device 6 to ensure that the restraint device can deflect freely in the cavity and does not interfere with the inner walls of the front mounting plate 502 and the rear mounting plate 504.

[0073] The technical solution of this embodiment has the following beneficial effects: The modular structure realizes functional modularity: the sliding groove is composed of the front boss 5021 and the baffle 503, which is easy to process; the cavity is formed by the front mounting plate 502 and the rear mounting plate 504, and the cavity size can be changed by adjusting the fixed position of the rear mounting plate 504 to adapt to different specifications of cable restraint devices 6; at the same time, the fasteners 505 are used to connect and facilitate disassembly and maintenance. If a certain part is damaged, only the damaged part needs to be replaced, without replacing the entire sliding part 5, thus reducing maintenance costs.

[0074] Based on the technical solution of this embodiment, refer to Figures 8 to 10 The top and / or bottom ends of the front mounting plate 502 extend to form a first guide bend 5023 for guiding and supporting the cable 3, and / or the top and / or bottom ends of the rear mounting plate 504 extend to form a second guide bend 5041 for guiding and supporting the cable 3.

[0075] When cable 3 enters the sliding component 5 from the fixed base 1, if it directly enters the cable restraint device 6, it is prone to friction with the top edge of the front mounting plate 502, resulting in wear of the outer sheath. Furthermore, the weight of cable 3 may cause it to sag, increasing the length burden. Therefore, a first guide bend 5023 is formed extending from the top and / or bottom of the front mounting plate 502, and / or a second guide bend 5041 is formed extending from the top and / or bottom of the rear mounting plate 504. Both the first guide bend 5023 and the second guide bend 5041 are bent in the direction of cable 3 laying, forming a smooth transition surface. After cable 3 exits from the fixed base 1, it first slides along the arc surface of the first guide bend 5023 before entering the cable restraint device 6. The arc transition of the first guide bend 5023 can avoid rigid contact between cable 3 and the edge of the front mounting plate 502. At the same time, the upper surface of the first guide bend 5023 can support the weight of cable 3, preventing cable 3 from sag due to its own weight and reducing the additional length requirement of cable 3. For example, a first guide bend 5023 is provided on the top of the front mounting plate 502. The cable 3 extends upward from the fixed base 1, turns to the horizontal direction along the arc surface of the first guide bend 5023, and enters the restraint device to prevent the cable 3 from forming an acute angle bend at the top of the mounting plate. The second guide bend 5041 can guide the cable 3 to make the cable 3 more regularly arranged.

[0076] The technical solution of this embodiment has the following beneficial effects: the guide bend plate effectively protects the outer sheath of the cable 3 and avoids the edge of the mounting plate from scratching and abrading the cable 3; at the same time, it supports the weight of the cable 3, prevents the length redundancy or tightness caused by sagging, and further reduces the mechanical fatigue of the cable 3; in addition, the first guide bend plate 5023 and the second guide bend plate 5041 can guide the cable 3 to ensure that the cable 3 is arranged more regularly and improve the aesthetics of the equipment.

[0077] In addition to polishing, the inner arc surfaces of the first guide bend 5023 and the second guide bend 5041 can also be coated with polytetrafluoroethylene to further reduce the sliding friction of the cable 3, or a rubber coating can be applied to increase cushioning and protect the fragile cable 3.

[0078] refer to Figures 1 to 13 The working principle of the sliding cable bracket of the present invention will be explained below with reference to the operation steps of specific embodiments.

[0079] The specific structure of the sliding cable bracket is as follows:

[0080] Support rail 4: Two parallel solid stainless steel linear guide rods 401, connected at both ends by an integrally formed limiting cylinder 402. The support rail 4 is fixed to the side wall of the fixed base 1 by bolts.

[0081] Sliding component 5: The front mounting plate 502 is made of stainless steel. The upper and lower sides of the front boss 5021 are provided with lubrication groove arc surfaces. The top is provided with a first guide plate 5023 with rubber coating. The baffle 503 is made of stainless steel and is fixed to the front boss 5021 by internal hex screws. The rear mounting plate 504 is made of stainless steel and is fixed to the rear boss 5022 by internal hex screws. The front boss 5021, the baffle 503 and the front mounting plate 502 form two upper and lower sliding grooves. The front mounting plate 502 and the rear mounting plate 504 form a cavity under the support of the rear boss 5022.

[0082] Cable restraint device 6: The first cable rack 601 and the second cable rack 602 with rubber pads and U-shaped grooves are both made of plastic and are fastened by trapezoidal tenon and mortise structure. A solid second-stage rotating column (8mm in diameter and 12mm in shoulder diameter) is set in the middle of the back side, and second-stage auxiliary columns 603 (6mm in diameter and 10mm in shoulder diameter) are set on both sides respectively.

[0083] Other structures: The front mounting plate 502 and the rear mounting plate 504 have arc-shaped slots 501 with an arc of 60° and the rotating column as the center. The auxiliary column 603 is housed in the arc-shaped slots 501. The rotating column and the shaft holes 8 of the front and rear mounting plates 504 are fitted with an H7 / g6 clearance fit.

[0084] Work process

[0085] In this embodiment, the cable 3 needs to enter the rotating component 2 from the fixed base 1.

[0086] Installation stage: Fix the support rail 4 to the fixed base 1 with bolts; separate the two tenon-and-mortise fastened first cable rack 601 and second cable rack 602, put the cable 3 into the U-shaped groove (rubber pad layer protects the cable) of one cable rack, and fasten the other cable rack (trapezoidal tenon to prevent detachment); install the cable restraint device 6 into the cavity between the front mounting plate 502 and the rear mounting plate 504, insert the rotating column into the shaft hole 8 (the shaft shoulder abuts against the inside of the front mounting plate 502), and insert the auxiliary column 603 into the arc-shaped strip hole 501; fix the baffle 503 and the rear mounting plate 504 with hexagonal screws to complete the assembly.

[0087] Initial state: Rotating component 2 is in a horizontal initial position, sliding component 5 is in the middle of support rail 4, cable 3 is constrained in the closed channel formed by first cable frame 601 and second cable frame 602, and first guide plate 5023 supports cable 3 to prevent sagging.

[0088] Rotating component 2 rotates at a high angle: Rotating component 2 rotates around the ear axis at a high angle (e.g., +90°), and cable 3 is dragged by rotating component 2, generating axial force to drive sliding component 5 to slide along support guide rail 4, compensating for the length requirement of cable 3 (about 50mm) and preventing cable 3 from being too tight; at the same time, cable 3 twists, causing cable restraint device 6 to deflect around rotating column, and auxiliary column 603 slides along arc-shaped slot 501 to the maximum angle (+90°), and is blocked by the end of arc-shaped slot 501, limiting excessive deflection; first guide bend plate 5023 and second guide bend plate 5041 guide cable 3 to slide, avoiding wear.

[0089] Rotating component 2 rotates at a low angle: Rotating component 2 rotates to a low angle (e.g., -25°), the cable 3 relaxes and generates a reverse tension, which drives the sliding component 5 to slide along the support guide rail 4, releasing the redundant length of the cable 3; the cable 3 twists in the reverse direction, the cable constraint device 6 deflects in the reverse direction, and the auxiliary column 603 slides in the reverse direction along the arc-shaped slot 501 and is limited again; throughout the process, the two guide rods 401 ensure smooth sliding, the limiting cylinder 402 prevents the sliding component 5 from derailing, and the second-order shoulder prevents the component from moving.

[0090] Reciprocating motion: When the rotating part 2 pitches continuously, the sliding part 5 slides back and forth along the guide rod 401, and the cable restraint device 6 deflects synchronously, always keeping the cable 3 in a matching length and stable posture, without tension, twisting or wear, and the cable 3 is neatly arranged, which is convenient for maintenance.
