[0028] The following is for reference. Figures 1-4 The cable laying device 100 according to an embodiment of the present invention is described. The cable 3 can be accommodated by the outer cylinder structure 1. The cable laying tube 2 is provided in the outer cylinder structure 1 to realize the winding and unwinding of the cable 3. The cable 3 can be neatly arranged on the outer peripheral wall of the cable laying tube 2 and the cable 3 can be prevented from coming out. The overall structure is relatively simple and can reduce the setting of the moving mechanism, reduce the overall volume of the cable laying device 100, and facilitate the setting of the cable laying device 100.

[0029] like Figure 1 As shown, a cable routing device 100 according to an embodiment of the present invention includes: an outer cylinder structure 1 and a cable routing cylinder 2.

[0030] The outer cylinder structure 1 has a cable routing cavity 11 inside, and the outer cylinder structure 1 has a cable outlet 12 communicating with the cable routing cavity 11. The cable routing drum 2 is rotatably installed inside the outer cylinder structure 1. The outer peripheral wall of the cable routing drum 2 has a cable routing groove 21. The cable routing groove 21 extends spirally along the axial direction of the cable routing drum 2. The gap between the outer peripheral wall of the cable routing drum 2 and the inner peripheral wall of the cable routing cavity 11 is smaller than the radial dimension of the cable 3 in the cable routing drum 2, so that the cable 3 is wound or released along the cable routing groove 21 when the cable routing drum 2 rotates.

[0031] Specifically, the cable routing device 100 includes an outer cylinder structure 1 and a cable routing drum 2. The outer cylinder structure 1 is used to contain and protect the cable 3, and the cable routing drum 2 is used to retract and extend the cable 3, so that the cable 3 can be neatly arranged on the outer peripheral wall of the cable routing drum 2 to prevent the cable 3 from getting tangled and inconvenient to use. The outer cylinder structure 1 is formed with a cable routing cavity 11, so that the outer cylinder structure 1 can contain the cable 3 through the cable routing cavity 11. The outer cylinder structure 1 is provided with a cable outlet 12, so that one end of the cable 3 can extend out from the cable outlet 12 to connect the cable 3 to other objects. The cable outlet 12 is connected to the cable routing cavity 11, so that one end of the cable 3 contained inside the cable routing cavity 11 can extend out from the cable outlet 12 to connect to other objects.

[0032] Meanwhile, by placing the cable tray 2 inside the outer cylinder structure 1, the cable tray 2 can be installed, and it can rotate relative to the outer cylinder structure 1. This rotation allows for the winding and unwinding of the cable 3. Furthermore, the outer peripheral wall of the cable tray 2 has a cable groove 21 for accommodating and guiding the cable 3, allowing it to be arranged along the extension direction of the groove 21. This results in the cable 3 being neatly arranged on the cable tray 2. Even when the cable reel 2 rotates relative to the outer cylinder structure 1, allowing the cable 3 to be wound or unwound along the cable groove 21, the cable reel 2 can be wound up when rotating clockwise and unwound when rotating counterclockwise, or wound up when rotating counterclockwise and unwound when rotating clockwise, thus improving the flexibility of the cable winding.

[0033] It should be noted that the diameter of the cable tray 21 can be slightly larger than the diameter of the cable 3, so as to facilitate the winding and unwinding of the cable 3, and to reduce the friction between the cable 3 and the cable tray 21, effectively preventing wear of the cable 3.

[0034] Furthermore, the cable tray 21 extends spirally along the axial direction of the cable tray 2, so that even when the cable 3 is arranged along the cable tray 21 on the outer peripheral wall of the cable tray 2, it can move simultaneously from one end of the cable tray 2 to the other end, preventing the cable 3 from being wound around the same position on the cable tray 2, thus avoiding tangling. This also reduces the need for a moving mechanism, decreases the overall volume of the cable tray 100, and facilitates its installation. Simultaneously, a certain gap exists between the outer peripheral wall of the cable tray 2 and the inner peripheral wall of the cable tray cavity 11 to facilitate the handling of the cable. The arrangement of the wires 3 and 2 avoids friction between the wires 3 and the inner wall of the wiring cavity 11, which could lead to damage to the wires 3. Furthermore, the gap between the outer wall of the wiring drum 2 and the inner wall of the wiring cavity 11 is smaller than the radial dimension of the wires 3 in the wiring drum 2. This prevents the wires 3 from rebounding and contacting the inner wall of the wiring cavity 11 when the tension on the wires 3 disappears. At this time, the inner wall of the wiring cavity 11 and the wires 3 will keep the wires 3 stationary due to friction, thus preventing the wires 3 from coming out of the wiring groove 21 and getting tangled.

[0035] Therefore, the outer cylinder structure 1 can accommodate the rope 3, and the cable tray 2 is set inside the outer cylinder structure 1 to realize the winding and unwinding of the rope 3. The cable tray 21 is formed on the outer peripheral wall of the cable tray 2 and the cable tray 21 extends spirally along the axial direction of the cable tray 2. Thus, when the cable tray 2 rotates, the rope 3 can be neatly arranged along the cable tray 21 on the outer peripheral wall of the cable tray 2, and the gap between the outer peripheral wall of the cable tray 2 and the inner peripheral wall of the cable tray cavity 11 is smaller than the radial dimension of the rope 3 in the cable tray 2, which can prevent the rope 3 from coming out.

[0036] According to the embodiment of the present invention, the cable laying device 100 can accommodate the cable 3 through the outer cylinder structure 1. By setting the cable laying tube 2 inside the outer cylinder structure 1, the cable 3 can be wound and unwound, and the cable 3 can be neatly arranged on the outer peripheral wall of the cable laying tube 2, and the cable 3 can be prevented from coming out. The overall structure is relatively simple, and the setting of the moving mechanism can be reduced, the overall volume of the cable laying device 100 can be reduced, which is beneficial to the setting of the cable laying device 100.

[0037] In some embodiments, the cable tray 2 has a wire hole 22 and a wire pressing thread hole 23 formed at one end of the cable tray 21. One end of the cable 3 is adapted to be fixedly inserted through the wire hole 22 and the wire pressing thread hole 23 and fixed to the cable tray 2 by a wire pressing screw.

[0038] Specifically, such as Figure 3 As shown, the cable tray 2 has a threaded hole 22 and a threaded hole 23. The threaded hole 22 allows one end of the cable 3 to pass through, and the threaded hole 23 secures one end of the cable 3 for easy arrangement. One end of the cable 3 can be inserted through the threaded hole 22 and extended to the threaded hole 23. Then, the end of the cable 3 is pressed together by the engagement between the cable pressing screw and the threaded hole 23, thus fixing one end of the cable 3 to the cable tray 2. This arrangement facilitates the arrangement of the cord 3, and ensures that the thread hole 22 and the threaded hole 23 are located at the same end of the cable tray 21. This allows the distance between the thread hole 22 and the threaded hole 23 to be relatively close, making it easier to insert one end of the cord 3 through the thread hole 22 and extend it into the threaded hole 23 for fixation within the threaded hole. It also prevents interference between the cord 3 located between the thread hole 22 and the threaded hole 23 and the cord 3 within the cable tray 21, which would otherwise prevent the cord 3 from being wound up or unwound.

[0039] The threaded hole 23 can be made into an internal thread and the wire pressing screw can be made into an external thread. The connection between the two can be achieved by the threaded connection, which can fix one end of the wire rope 3 so as to facilitate the winding and unwinding of the wire rope 3. The end of the wire rope 3 fixed at the threaded hole 23 and the end of the wire rope 3 extending from the outlet 12 are the two ends of the wire rope 3.

[0040] In some embodiments, the wire hole 22 and the wire thread hole 23 are both located at the same end of the outer peripheral wall of the cable tray 2, and the opening direction of the wire hole 22 is tangent to one end of the cable tray 21.

[0041] Specifically, a threading hole 22 and a threaded hole 23 are formed on the cable tray 2. The threading hole 22 and the threaded hole 23 together fix one end of the cable 3, facilitating the winding and unwinding of the cable 3. Furthermore, by placing both the threading hole 22 and the threaded hole 23 at the same end of the outer peripheral wall of the cable tray 2, the distance between them is minimized, allowing one end of the cable 3 to be threaded through the threading hole 22 and extend into the threaded hole 23. The wire is fixed in the threaded hole, which avoids interference between the wire 3 located between the thread hole 22 and the threaded hole 23 and the wire 3 in the cable tray 21, thus preventing the wire 3 from being wound up or unwound. Also, the opening direction of the thread hole 22 is tangent to one end of the cable tray 21, which facilitates the arrangement of the wire 3 connected to one end of the wire 3 fixed at the threaded hole 23 along the cable tray 21, and prevents the wire 3 from bending at this point, which would cause the wire 3 to wear and break.

[0042] In some embodiments, there are at least two cable trays 21, and the at least two cable trays 21 are distributed in parallel and spaced apart on the outer peripheral wall of the cable tray 2.

[0043] Specifically, a wiring groove 21 is provided on the wiring drum 2. The wiring groove 21 is used to accommodate and guide the wire 3. At least two wiring grooves 21 can be provided on the wiring drum 2, that is, the number of wiring grooves 21 can be two, three or more. Each wiring groove 21 can accommodate the wire 3. That is, as the number of wiring grooves 21 increases, the number of wires 3 arranged on the wiring drum 2 can increase. In this way, at least two wires 3 can be wound and unwound simultaneously by at least two wiring grooves 21, which can improve the efficiency of the wiring device 100. At the same time, at least two wiring grooves 21 are evenly distributed on the outer peripheral wall of the wiring drum 2 to facilitate the winding and unwinding of the wires 3. And at least two wiring grooves 21 are parallel and spaced apart, which can keep the wires 3 in the at least two wiring grooves 21 parallel and spaced apart, which can avoid interference between at least two wires 3 and prevent the wires 3 from getting tangled.

[0044] In some embodiments, the outlet 12 is configured as an elongated opening and extends along the axial direction of the cable tray 2; wherein, along the axial direction of the cable tray 2, the extension length of the outlet 12 is greater than or equal to the axial length of the cable tray 21.

[0045] Specifically, an outlet 12 is provided on the outer cylinder structure 1. The outlet 12 allows one end of the rope 3 to extend out for connection with other objects. By constructing the outlet 12 as a long strip, the length of the outlet 12 can be increased to allow one end of the rope 3 to extend out. Furthermore, by extending the outlet 12 along the axial direction of the cable tray 2, the outlet 12 can extend along the arrangement direction of the rope 3, so that one end of the rope 3 can extend out from the nearest outlet 12. Moreover, by making the extension length of the outlet 12 greater than or equal to the extension length of the cable tray 21, regardless of the length of the rope 3 or the arrangement of the rope 3 on the cable tray 2, one end of the rope 3 can always extend out from the nearest outlet 12 for connection with other objects.

[0046] In some embodiments, a guide surface 121 is formed on one side edge of the outlet 12, the cord 3 is adapted to be guided out along the guide surface 121, and the guide surface 121 is tangent to the cable tray 21.

[0047] Specifically, the outlet 12 allows one end of the cord 3 to extend out for connection with other objects. The cable tray 21 accommodates and guides the cord 3, allowing it to be neatly arranged along the extension direction of the cable tray 21. One side edge of the outlet 12 forms a guide surface 121, which guides one end of the cord 3 so that it can extend out from the outlet 12 along the guide surface 121. At the same time, the guide surface 121 is tangent to the cable tray 21 so that when one end of the cord 3 moves to a position on the cable tray 21 directly opposite the outlet 12, it can extend out from the direction tangent to the cable tray 21 along the guide surface 121, thus preventing the cord 3 from bending and being easily damaged.

[0048] It should be noted that the outlet surface 121 can extend along the axial direction of the cable tray 2, and its length is the same as that of the outlet 12, so that the cable 3 can be discharged from any position on the outlet 12 along the outlet surface 121. Furthermore, both sides of the outlet 12 can form outlet surfaces 121, so that when the rotation direction of the cable tray 2 changes with the winding direction of the cable 3, the cable 3 can also be discharged along the outlet surface 121.

[0049] In some embodiments, the outer cylinder structure 1 includes a wire-blocking cylinder 13 and a cover plate 14. A wire-laying cavity 11 with one end open is formed inside the wire-blocking cylinder 13. The cover plate 14 is connected to one end of the wire-blocking cylinder 13 and is used to close the open end of the wire-laying cavity 11. The two ends of the wire-laying cylinder 2 are rotatably supported on the cover plate 14 and the wire-blocking cylinder 13, respectively. The wire outlet 12 is provided in the wire-blocking cylinder 13.

[0050] Specifically, the outer cylinder structure 1 includes a wire-blocking cylinder 13 and a cover plate 14. The wire-blocking cylinder 13 forms a wire-laying cavity 11, which can be used to accommodate and shield the wire 3 to prevent it from coming out of the wire-laying groove 21. One end of the wire-laying cavity 11 is open, and the cover plate 14 can be connected to one end of the wire-blocking cylinder 13 to seal the open end of the wire-laying cavity 11, preventing the wire 3 from coming out. The two ends of the wire-laying cylinder 2 are respectively supported by the cover plate 14 and the wire-blocking cylinder 13. The two ends of the cable tray 2 can be connected to the cover plate 14 and the cable retainer 13 respectively to install the cable tray 2, ensure the reliability of the cable tray 2, and make the cable tray 2 rotatably connected to the cover plate 14 and the cable retainer 13. This allows the cable tray 2 to rotate relative to the cover plate 14 and the cable retainer 13, so that the cable tray 2 can retract and extend the cable 3 when rotating. Furthermore, the cable outlet 12 is set on the cable retainer 13 so that the cable outlet 12 can be opened outward so that one end of the cable 3 can extend from the cable outlet 12 and connect to other objects.

[0051] It should be noted that, for example Figure 2 As shown, the cable tray 2 is rotatably connected to the cover plate 14 and the cable retainer 13, so that the two ends of the cable tray 2 are respectively formed with shoulders 24. The cable tray 2 is then connected to the cover plate 14 and the cable retainer 13 respectively from the two shoulders 24 through two bearings 4, so that the cable retainer 13 can rotate relative to the cover plate 14 and the cable retainer 13.

[0052] In some embodiments, the cover plate 14 is detachably connected to the wire guide tube 13.

[0053] Specifically, the cable tray 2 is located inside the outer cylinder structure 1, that is, inside the cable tray cavity 11, with one end of the cable tray cavity 11 open, which facilitates the installation and replacement of the cable tray 2. The cover plate 14 and the cable retainer 13 are detachably connected, which facilitates connecting the cover plate 14 and the cable retainer 13 or separating the two. When the two are separated, one end of the cable tray cavity 11 is open, which facilitates the installation or replacement of the cable tray 2. When the two are connected, the cable tray cavity 11 is closed to prevent the cable tray 2 or the cable 3 from coming out of the cable tray cavity 11, which ensures the reliability of the operation of the cable tray 2.

[0054] For example, such as Figure 1 and Figure 4 As shown, the cover plate 14 and the wire guide tube 13 can be connected by connectors 5. The connection method is simple, reliable and easy to operate. Six connectors 5 can be used to connect at the same time to improve the connection reliability between the two. Furthermore, the six connectors 5 can be distributed at intervals to improve the connection stability between the two. The connectors 5 can be screws.

[0055] In some embodiments, the cable routing device 100 further includes a driving member connected to the cable routing drum 2 and used to drive the cable routing drum 2 to rotate within the cable routing cavity 11.

[0056] Specifically, the driving component is connected to the cable tray 2 so that the driving component can provide driving force for the rotation of the cable tray 2. Thus, the cable tray 2 can rotate automatically under the action of the driving component, thereby realizing the automatic winding and unwinding of the cable 3. In other words, the driving component can be used to drive the cable tray 2 to rotate in the cable tray cavity 11 to wind and unwind the cable 3.

[0057] The driving component can be a motor, which can wind up the rope 3 when the motor rotates forward and release the rope 3 when the motor rotates in reverse, or release the rope 3 when the motor rotates forward and wind up the rope 3 when the motor rotates in reverse. The setting method is flexible and selectable.

[0058] In some embodiments, the cable tray 21 is configured to have a cable cross-section, which can be circular, elliptical, square, or sheet-like.

[0059] Specifically, the cable tray 21 is used to accommodate and guide the cable 3, allowing the cable 3 to be wound and unwound along the cable tray 21. The cable tray 21 has a cable tray cross-section that can be adapted to the cross-section of the cable 3. The cable tray cross-section can be constructed as a circle, ellipse, square, or sheet shape, so that the cable tray 21 has cable tray cross-sections of different shapes. This allows the cable tray 21 to accommodate cables 3 with different cross-sectional shapes, which can increase the applicability of the cable tray device 100 and improve user satisfaction.

[0060] It should also be noted that when using the cable laying device 100, the cable 3 can be first fixed to the wire thread hole 23 with the wire pressing screw, and then the cable 3 can be pre-wound several times in the cable laying groove 21 on the cable laying drum 2. Then the cable laying drum 2 is rotated under the action of the driving component to achieve the arrangement of the cable 3. Finally, the cable 3 is led out from the outlet 12 on the cable blocking drum 13, so that the cable 3 can be neatly arranged on the cable laying drum.
