Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a wiring module and a treadmill using the wiring module. Background Technology

[0002] With the increasing popularity of home and commercial treadmills, users have placed higher demands on the portability, ease of transportation, and ease of assembly of these products. Traditional treadmills typically employ an integrated wiring design for their traction components, meaning that the cables between the control handles and the resistance and clutch devices are directly fixed and run through the uprights and frame.

[0003] However, this design has the following drawbacks: Since the cables of the uprights and frame cannot be separated, they must be packaged as a whole during transport. Although the uprights and frame are foldable, this still results in a large volume. If they are transported separately, users must assemble the cables themselves during installation. Users must manually thread the cables into the uprights and frame and precisely adjust the cable length and fixing position. This process is not only time-consuming but also prone to problems such as transmission failure and cable jamming due to misaligned cables, misaligned interfaces, or improper tension adjustment. Furthermore, the traditional design is extremely inconvenient for maintenance and repair, requiring the entire cable system to be disassembled for partial repairs, increasing maintenance costs and time.

[0004] To address the aforementioned issues, existing technologies urgently need improvement. Summary of the Invention

[0005] To address the aforementioned problems, the purpose of this invention is to provide a wiring module and a treadmill using the wiring module, which has the advantages of being easy to transport, assemble, and maintain, and improving the service life of cables.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This application provides a wiring module with the following technical solution: A wiring module includes a first unit and a second unit. The first unit includes a first housing and a control terminal cable reel assembly rotatably installed inside the first housing. The second unit includes a second housing and an execution terminal cable reel assembly rotatably installed inside the second housing. The control terminal cable reel assembly is used to connect control terminal cables, and the execution terminal cable reel assembly is used to connect execution terminal cables. When the first unit and the second unit are connected, the first housing and the second housing are interlocked to form a sealed housing structure. The first housing and / or the second housing are provided with wiring holes for the control terminal cables and execution terminal cables to pass through. The control terminal cable reel assembly and the execution terminal cable reel assembly achieve synchronous rotation through a circumferentially distributed linkage structure.

[0008] In this solution, two independent units (Unit 1 and Unit 2) with a split design each contain a shell structure with a rotating cable reel assembly. When connected, they form a sealed housing and enable synchronous rotation of the cable reels. This solution achieves rapid assembly and disassembly of cables through a modular, split design. The rotating cable reel assembly maintains continuous transmission, the linkage structure ensures synchronized movement after connection, and the sealed housing provides protection. The core advantage lies in solving the problem of traditional integrated cabling being inseparable through a physically separated modular structure. Simultaneously, the linkage mechanism maintains the integrity of the transmission function, and dedicated wiring modules enable rapid connection and separation. This allows the column and frame to be packaged completely independently, avoiding physical damage or tension imbalance of cables due to folding or compression during transportation.

[0009] This technical solution utilizes a modular design to break down cable connections into independently transportable units. During docking, the outer shells fit together to form a protective structure, and the linkage mechanism automatically establishes a transmission relationship. This minimizes transport volume while ensuring functional integrity after assembly, completely eliminating the need for manual cable threading and adjustment. The rotating reel assembly retains the traditional transmission method, and the linkage structure ensures the restoration of motion synchronization after separation.

[0010] Furthermore, this application proposes that the first housing is provided with a first locking pin for circumferentially locking the control-end coil assembly, and the second housing is provided with a second locking pin for circumferentially locking the execution-end coil assembly. When the first unit and the second unit are docked, the control-end coil assembly and the execution-end coil assembly are linked through a linkage structure. The first and second locking pins are removed after the first unit and the second unit are docked, allowing the control-end coil assembly and the execution-end coil assembly to rotate circumferentially. The first and second locking pins are used to fix the control-end coil assembly and the execution-end coil assembly, respectively, to prevent accidental rotation of the coil assembly during transportation or in a non-docked state. The linkage structure ensures the synchronous rotation of the two coil assemblies after docking. The design of removing the locking pins allows the coil assembly to rotate freely after docking, realizing the synchronous winding and unwinding function of the cable. This solution, through the removable locking pin structure, ensures both transportation stability and functional release after docking.

[0011] Furthermore, this application proposes that the first and second housings are respectively provided with through holes, and the first and second locking pins are respectively inserted into the corresponding through holes; after the first unit and the second unit are docked, the first and second locking pins can be pulled out from the through holes. The through holes are part of the physical structure of the housings, the through-hole fitting relationship between the locking pins and the through holes, and the pull-out characteristic of the locking pins after docking. The through holes provide an axial movement channel for the locking pins, the through-hole fitting ensures that the locking pins can effectively fix the coil assembly in the transportation / non-working state, and the pull-out characteristic allows the locking state to be released by a simple axial force operation. These features work together to ensure the stability of the coil assembly during transportation and to achieve the convenience of quick unlocking during use.

[0012] Furthermore, this application also proposes a T-shaped disassembly component, the end of which can pass through and be threadedly fixed to the central shaft hole of the first and second locking pins. Applying force to the T-shaped disassembly component allows the first and second locking pins to be pulled out of the through hole. The T-shaped disassembly component achieves mechanical fixation through the threaded connection structure between its end and the central shaft hole of the locking pin. This design utilizes the threaded connection to provide a stable force fulcrum; the T-shaped structure provides a force application point, reducing the need for manual pulling force; and the way the central shaft hole is inserted ensures that the direction of force coincides with the axis of the locking pin, avoiding jamming caused by off-center loading. The above features work together to achieve convenient disassembly of the locking pins through mechanical connection and mechanical optimization. This solution, through the standardized disassembly tool design, transforms the locking pin pulling action, which originally required manual operation, into a standardized mechanical operation, solving the problem of inconvenience in manual operation and avoiding component damage that may be caused by using sharp tools.

[0013] Furthermore, this application proposes that the control end cable reel assembly includes a first control end cable reel and a second control end cable reel coaxially arranged; the execution end cable reel assembly includes a first execution end cable reel and a second execution end cable reel coaxially arranged; after the first unit and the second unit are docked, the first control end cable reel and the first execution end cable reel achieve synchronous rotation through a circumferentially distributed first linkage structure, and the second control end cable reel and the second execution end cable reel achieve synchronous rotation through a circumferentially distributed second linkage structure. In this solution, the first and second control end cable reels, the first and second execution end cable reels, the first linkage structure, and the second linkage structure are coaxially arranged. These features solve the technical problem in the following ways: the coaxially arranged cable reel assembly allows the two sets of cables to be installed and operated independently; the first linkage structure ensures the synchronous rotation of the first control end cable reel and the first execution end cable reel, and the second linkage structure ensures the synchronous rotation of the second control end cable reel and the second execution end cable reel, thereby achieving independent control of the two sets of cables. The sealed shell structure formed after docking protects the internal components and maintains structural stability. This technical solution, through layered coaxial design and independent linkage structure, achieves independent synchronous control of two sets of cables in a single wiring module, solving the technical problem of independent transmission of multiple cable groups, while maintaining the compactness and reliability of the module.

[0014] Furthermore, the first control end reel, the second control end reel, the first execution end reel, and the second execution end reel are provided with positioning holes or positioning grooves that cooperate with the locking pins; the first locking pin passes through the first control end reel and the second control end reel to fix them to the first housing, and the second locking pin passes through the first execution end reel and the second execution end reel to fix them to the second housing. In this scheme, 1) all four reels are provided with positioning holes / grooves, forming a mechanical cooperation relationship with the locking pins to ensure that the reels cannot rotate in the non-connected state; 2) the first locking pin passes through two control end reels simultaneously to achieve axial and circumferential fixation; 3) the second locking pin passes through two execution end reels simultaneously to achieve the same fixation effect. These features work together: through the physical interference between the locking pins and the positioning structure, the reels are forced to remain stationary during transportation or separation; when the two units are connected and the locking pins are pulled out, all reels are simultaneously released from constraint, ensuring that the linkage structure can take effect immediately. This scheme, through mechanical interlocking design, avoids cable entanglement caused by accidental rotation of the reels during transportation, and ensures that all reels can enter the linkage state synchronously after connection.

[0015] Furthermore, this application proposes that the diameters of the second control coil and the second execution coil are larger than those of the first control coil and the first execution coil; when the first unit and the second unit are docked, the first control coil and the first execution coil are positioned between the second control coil and the second execution coil. In this scheme: 1) the second control coil / execution coil adopts a larger diameter design, forming an outwardly expanding coil structure; 2) the first control coil / execution coil is nested between the large-diameter coils. This design achieves spatial layering through differentiated coil diameters: the large-diameter coils provide external support and a larger torque transmission area, while the small-diameter coils achieve a compact layout on the inner side. The two pairs of coils form a stepped coaxial arrangement, ensuring both the meshing space of the linkage structure and avoiding motion interference between the coils. This structure enables the dual-coil system to achieve stable synchronous rotation within a limited shell space, while simultaneously meeting the wiring requirements of different cables. Through the nested design of coils with differentiated diameters, the space utilization of the multi-coil system is effectively optimized, ensuring accurate meshing of the inner and outer linkage structures during docking. This layout is particularly suitable for applications that require simultaneous control of multiple sets of cables.

[0016] Furthermore, this application proposes that the first linkage structure includes a first toothed block disposed on the opposing surfaces of the first control end coil and the first execution end coil, the first toothed block on the first control end coil meshing with the first toothed block on the first execution end coil; the second linkage structure includes a second toothed block disposed on the opposing surfaces of the second control end coil and the second execution end coil, the second toothed block being located on the outer surface of the first control end coil and the first execution end coil, the second toothed block on the second control end coil meshing with the second toothed block on the second execution end coil. This solution achieves the technical effect by setting an inner and outer double-layer meshing linkage structure: the first toothed block directly meshes on the opposing surfaces of the first control end coil and the first execution end coil to achieve transmission, and the second toothed block meshes on the opposing surfaces of the second control end coil and the second execution end coil to achieve transmission. This layered design ensures the synchronous rotation accuracy of the double coil assembly and avoids interference through the staggered arrangement of the inner and outer toothed blocks. This solution achieves dual linkage within a limited space through a spatially layered toothed block structure. This design not only solves the structural interference problem when multiple discs rotate synchronously, but also improves transmission reliability by increasing the number of meshing points, while utilizing the space on the outer disc surface to strengthen the transmission structure.

[0017] Furthermore, this application also proposes a treadmill, including a frame and two uprights mounted on the frame; a control handle is provided at the upper end of each upright and is connected to a resistance device or a clutch device via a traction assembly; the traction assembly includes a control cable connecting to the control handle, an execution cable connecting to the resistance device or the clutch device, and the aforementioned wiring module. Technical features include: the frame and uprights constitute the main framework; the control handle is connected to the resistance device or clutch device via the traction assembly; the traction assembly adopts a split cable design, including a control cable and an execution cable; the aforementioned wiring module enables detachable cable connection. These features work synergistically: the sealed housing structure and linkage rotation function of the wiring module ensure reliable transmission of the split cables after connection; the locking pin design facilitates fixing the cable reel assembly during transportation, and the rotation function can be restored by removing the locking pin during use; the split wiring allows the uprights and frame to be completely separated for transportation, and the user only needs to quickly connect the cables via the wiring module.

[0018] Furthermore, this application also proposes a treadmill, including a frame and two uprights mounted on the frame; a control handle is provided at the upper end of each upright, and a resistance device and a clutch device are respectively connected through a first traction component and a second traction component; the first traction component includes a control cable connecting to the control handle and an execution cable connecting to the resistance device, and the second traction component includes a control cable connecting to the control handle and an execution cable connecting to the clutch device; the treadmill also includes the aforementioned wiring module, wherein the control cable and execution cable of the first traction component are respectively connected to a first control reel and a first execution reel, and the control cable and execution cable of the second traction component are respectively connected to a second control reel and a second execution reel. This treadmill adopts a dual traction component design, respectively connecting the resistance device and the clutch device, and the wiring module enables a detachable connection between the control and execution cables. The wiring module includes a coaxially arranged double-layer reel structure (first control reel / second control reel and first execution reel / second execution reel), achieving synchronous rotation through a linkage structure. This design allows the traction components to be separated from the chassis during transport, and the cables are pre-connected to the corresponding reels at the factory and automatically aligned via a linkage structure, avoiding errors from manual threading. The modular design requires only the user to connect the first and second units and remove the first and second locking pins. Thus, the double-layer reel structure can independently control two traction systems, the linkage structure ensures transmission synchronization, and the locking pin removal mechanism guarantees free rotation after connection. The technical solution replaces traditional fixed wiring with detachable connections through a modular wiring design, utilizes a linkage structure to eliminate assembly deviations, and the double-layer reels achieve independent control of multiple traction paths. During transport, the cables are separated from the main body, reducing volume. During assembly, the mechanical linkage automatically calibrates the cable position, fundamentally solving the transmission failure problems caused by misalignment and difficulty in adjusting tension in traditional solutions.

[0019] This invention proposes an innovative solution to the above-mentioned problems:

[0020] 1. Modular segmented cable design: The control cable (connecting the handle) and the actuator cable (connecting the resistance / clutch device) of the traction component are segmented and quickly connected and disconnected through a dedicated wiring module, so that the column and the frame can be packaged completely independently, avoiding physical damage to the cable or loss of tightness due to folding and squeezing during transportation;

[0021] 2. Integrated connection and linkage: The wiring module consists of the first unit and the second unit. Users only need to fit the outer shell of the two units together to complete the electrical connection of the cable and the circumferential linkage engagement of the cable reel at the same time, completely eliminating the need for manual wiring and adjustment.

[0022] 3. Locking pin protection and rotation release: During transportation, the locking pin secures the circumferential position of the reel to prevent the cable from loosening or tangling; after assembly, pulling out the locking pin releases the reel's rotation function, ensuring both transmission flexibility and transportation safety.

[0023] This solution fundamentally resolves the contradiction between modular transportation and rapid assembly. It reduces transportation risks through modular design, ensures a user-friendly assembly experience through linkage structure and locking mechanism, and improves the reliability and lifespan of cable transmission.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0036] Example 1:

[0037] like Figure 1-5As shown, this embodiment relates to a wiring module, including a first unit 1 and a second unit 2. The first unit 1 includes a first housing 11 and a control terminal cable reel assembly 12 rotatably mounted inside the first housing 11. The second unit 2 includes a second housing 21 and an execution terminal cable reel assembly 22 rotatably mounted inside the second housing 21. The control terminal cable reel assembly 12 is used to connect control terminal cables, and the execution terminal cable reel assembly 22 is used to connect execution terminal cables. When the first unit 1 and the second unit 2 are connected, the first housing 11 and the second housing 21 interlock to form a sealed housing structure. The first housing 11 and / or the second housing 21 are provided with wiring holes 18 for the control terminal cables and execution terminal cables to pass through. The control terminal cable reel assembly 12 and the execution terminal cable reel assembly 22 achieve synchronous rotation through circumferentially distributed linkage structures (including a first linkage structure and a second linkage structure). The control terminal cable reel assembly 12 and the execution terminal cable reel assembly 22 can adopt a coaxial dual-reel or multi-reel structure. The linkage structure may include meshing tooth blocks (such as the first tooth block 7 and the second tooth block 8) disposed on the opposite surfaces of the coils. The tooth blocks may have a trapezoidal or rectangular cross-section design to ensure meshing stability. The housing fitting structure may adopt a concave-convex mating annular groove design, and a sealing ring may be provided on the mating surface to improve sealing performance. The coil assembly may be rotated using a bearing support method, and the bearings may be deep groove ball bearings or sliding bearings.

[0038] This technical solution breaks down traditional integrated cabling into independently transportable units through a modular, split design. During assembly, the outer shell automatically fits together to form a protective structure, and a linkage mechanism ensures synchronized rotation of the cable reels. The split structure solves the problem of excessive transport volume, and the linkage structure of the rotating cable reel assembly ensures the restoration of motion synchronization after separation. Using this structure, the control-end cable and control-end cable reel assembly 12, and the execution-end cable and execution-end cable reel assembly 22 are pre-assembled at the factory. During user assembly, only the first unit 1 and the second unit 2 need to be connected. Compared to existing technologies, this solution avoids manual wiring and adjustment processes, achieving rapid assembly and disassembly of cable connections through physically separated modular design, while maintaining the integrity of the transmission function through the linkage mechanism. The sealed housing structure provides protection while ensuring a stable working environment for the transmission components.

[0039] like Figure 2-5 As shown, the first housing 11 is provided with a first locking pin 13 for circumferentially locking the control terminal coil assembly 12.

[0040] The second outer shell 21 is provided with a second locking pin 23 for circumferentially locking the actuator coil assembly 22. When the first unit 1 and the second unit 2 are docked, the control coil assembly 12 and the actuator coil assembly 22 are linked by a linkage structure. The first locking pin 13 and the second locking pin 23 are removed after the first unit 1 and the second unit 2 are docked, so that the control coil assembly 12 and the actuator coil assembly 22 can rotate circumferentially. Compared with the prior art, this solves the problem of structural damage caused by the free rotation of the coil during split transportation and realizes immediate functional conversion after docking without additional debugging steps. Furthermore, the first outer shell 11 and the second outer shell 21 are respectively provided with through holes 3, and the first locking pin 13 and the second locking pin 23 are respectively inserted into the corresponding through holes 3. After the first unit 1 and the second unit 2 are docked, the first locking pin 13 and the second locking pin 23 can be pulled out from the through holes 3. Specifically, the locking pin can be a cylindrical metal rod, the diameter of which forms a transition fit with the through hole 3 of the outer shell, ensuring that the locking pin can be firmly inserted and manually pulled out. The through hole 3 is located in the axial position of the outer shell, and its diameter forms a transition fit or a small clearance fit with the diameter of the locking pin. As a preferred embodiment, a guide slope can be provided on the inner wall of the through hole 3 to assist the insertion of the locking pin. In another embodiment, the locking pin can be a cylindrical pin, a tapered pin, or a stepped pin, wherein the shoulder structure of the stepped pin can limit the insertion depth. Specifically, an annular groove can be provided at the end of the locking pin, and temporary fixation can be achieved by an elastic buckle. This technical solution realizes the rapid release of the rotational freedom of the coil assembly through the axially detachable fit between the through hole 3 and the locking pin. The through hole 3 provides a precise axial movement trajectory for the locking pin, and the through fit ensures that the locking pin does not move axially during transportation. The design of direct pull-out after docking avoids complex operations such as threaded disassembly. Thus, while ensuring structural stability, the locking state can be switched by applying only linear force. Compared with existing technologies, this solution significantly improves assembly efficiency and reduces operational complexity through the reversible locking design of the mechanical structure.

[0041] like Figure 1As shown in Figures 4 and 5, this solution also provides a T-shaped disassembly component 4. The end of the T-shaped disassembly component 4 can pass through the central shaft hole of the first locking pin 13 and the second locking pin 23 and be threadedly fixed thereto. Applying force to the T-shaped disassembly component 4 can pull the first locking pin 13 and the second locking pin 23 out of the through hole 3. Specifically, the horizontal bar portion of the T-shaped disassembly component 4 forms a hand-held force application part, and its vertical bar end is provided with an external thread structure. The inner wall of the central shaft hole is machined with a matching internal thread. In this way, this technical solution establishes a rigid force transmission path through the threaded connection, directly applying axial tensile force to the central axis of the locking pin. The T-shaped structure amplifies the torque, allowing the operator to generate sufficient pulling force with only a small gripping force. The way the central shaft hole is inserted ensures that the direction of force is completely consistent with the movement trajectory of the locking pin, eliminating frictional resistance caused by lateral force. Compared with manual operation, this design transforms the locking pin disassembly process into a standardized mechanical action, avoiding component damage caused by improper force application and significantly reducing the intensity of operation.

[0042] like Figure 2-5 As shown, the control end coil assembly 12 includes a first control end coil 121 and a second control end coil 122 coaxially arranged. The execution end coil assembly 22 includes a first execution end coil 221 and a second execution end coil 222 coaxially arranged. After the first unit 1 and the second unit 2 are docked, the first control end coil 121 and the first execution end coil 221 achieve synchronous rotation through a circumferentially distributed first linkage structure, and the second control end coil 122 and the second execution end coil 222 achieve synchronous rotation through a circumferentially distributed second linkage structure. Specifically, the first linkage structure and the second linkage structure can adopt a gear meshing method.

[0043] To achieve synchronous rotation, this technical solution utilizes a layered coaxial design and independent linkage structure to achieve independent synchronous control of two sets of cables within a single wiring module. The coaxially arranged cable reel assembly allows for independent installation and operation of the two sets of cables. The first linkage structure ensures synchronous rotation of the first control end cable reel 121 and the first execution end cable reel 221, while the second linkage structure ensures synchronous rotation of the second control end cable reel 122 and the second execution end cable reel 222, thus achieving independent control of the two sets of cables. The sealed housing structure formed after docking protects the internal components and maintains structural stability. Compared with existing technologies, this solution solves the technical challenge of independent transmission of multiple cable groups while maintaining the compactness and reliability of the module.

[0044] In a further embodiment, the first control end reel 121, the second control end reel 122, the first execution end reel 221, and the second execution end reel 222 are provided with positioning holes 9 or positioning grooves 10 that cooperate with the locking pins. The first locking pin 13 passes through the first control end reel 121 and the second control end reel 122 to fix them to the first housing 11, and the second locking pin 23 passes through the first execution end reel 221 and the second execution end reel 222 to fix them to the second housing 21. The positioning holes 9 or positioning grooves 10 can be implemented in the following ways: a circular through hole forms a clearance fit with the cylindrical locking pin to ensure that the locking pin can be axially pulled out; a rectangular groove forms a surface contact with the flat locking pin to enhance the anti-torsion ability; a tapered hole and a tapered locking pin achieve self-centering and improve assembly accuracy. The locking pin is fixed by: an elastic buckle at the end of the locking pin engaging with the housing. This technical solution achieves a dual effect through mechanical interlocking design: in the non-interlocking state, the physical interference between the locking pin and the positioning structure forcibly restricts the rotation of the reel, preventing cable entanglement during transportation. Upon simultaneous removal of the locking pins after docking, all four sets of reels are immediately released from their constraints, ensuring the linkage structure takes effect instantly. Specifically, the engagement of the positioning hole 9 / positioning groove 10 with the locking pins forms a rigid anti-rotation mechanism. Compared to the existing method of fixing a single reel separately, this solution uses a through-type locking pin to simultaneously fix the coaxial double reels. This not only simplifies the locking structure but also achieves absolute synchronous fixing and release of the two reels through the shared locking pin. This solves the problem of cable tangling caused by free rotation of the reels during separate transport and ensures that all reels can simultaneously enter the linkage state after docking, eliminating the risk of asynchronous transmission due to individual reels not being unlocked in time.

[0045] Furthermore, the diameters of the second control end coil 122 and the second execution end coil 222 are larger than those of the first control end coil 121 and the first execution end coil 221. When the first unit 1 is docked with the second unit 2, the first control end coil 121 and the first execution end coil 221 are positioned between the second control end coil 122 and the second execution end coil 222. In the nested arrangement, the axial center plane of the smaller diameter coil coincides with the axial center plane of the larger diameter coil, with a 2-5mm operating clearance between them. Thus, this technical solution forms a stepped coaxial arrangement structure through diameter differentiation design. The larger diameter coil provides a larger torque transmission area and structural support on the outer side, while the smaller diameter coil achieves a compact layout on the inner side. The nested arrangement allows the linkage structures of the two sets of coils to be staggered in axial space, avoiding rotational interference. In specific implementation, the linkage teeth of the outer large-diameter coil can be set on the outer edge of the coil surface, and the linkage teeth of the inner small-diameter coil can be set on the inner side of the coil surface, with the two sets of teeth forming a complementary distribution in the radial direction. This structure ensures synchronous rotation accuracy while reducing the axial dimension of the dual-coil system compared to the traditional parallel arrangement. Through spatial layering design, it meets the independent wiring requirements of multiple cables while ensuring the overall compactness of the housing structure.

[0046] Specifically, the first linkage structure includes a configuration on the opposite side of the first control terminal panel 121 and the first execution terminal panel 221.

[0047] The first tooth block 7 on the first control end wire disk 121 meshes with the first tooth block 7 on the first execution end wire disk 221. The second linkage structure includes a second tooth block 8 disposed on the opposing surfaces of the second control end wire disk 122 and the second execution end wire disk 222. The second tooth block 8 is located on the outer surface of the first control end wire disk 121 and the first execution end wire disk 221, and meshes with the second tooth block 8 on the second control end wire disk 122. The first tooth block 7 and the second tooth block 8 can adopt involute tooth shape, circular arc tooth shape, triangular tooth shape, or trapezoidal tooth shape, and the number of tooth blocks is set to 2-6 according to the transmission ratio requirements. The meshing surfaces of the tooth blocks can be surface hardened, such as carburizing and quenching or chrome plating.

[0048] This technical solution achieves its effect through a spatially layered double-layered toothed block structure: the first toothed block 7 directly meshes with the opposing surfaces of the first control end coil 121 and the first execution end coil 221 to achieve transmission, while the second toothed block 8 meshes with the opposing surfaces of the second control end coil 122 and the second execution end coil 222 to achieve transmission. This layered design ensures the synchronous rotation accuracy of the double coil assembly and avoids interference through the staggered arrangement of the inner and outer toothed blocks. This solution achieves dual linkage within a limited space through the spatially layered toothed block structure. This design not only solves the structural interference problem when multiple coils rotate synchronously, but also improves transmission reliability by increasing the number of meshing points, while strengthening the transmission structure by utilizing the space on the outer coil surface.

[0049] Example 2:

[0050] like Figure 6 As shown, this embodiment also proposes a treadmill, including a frame and two uprights mounted on the frame. A control handle is provided at the upper end of each upright and is connected to a resistance device or a clutch device via a traction assembly. The traction assembly includes a control cable connecting to the control handle, an execution cable connecting to the resistance device or clutch device, and the wiring module described in Embodiment 1. Thus, this technical solution achieves a detachable design for the traction assembly through a modular wiring structure. During transportation, the uprights and frame can be completely separated, and the locking pin in the wiring module secures the cable reel assembly to prevent rotation. During use, simply connecting the two units of the wiring module and removing the locking pin restores the cable's transmission function.

[0051] In a further embodiment, a control handle is provided at the upper end of the column, and a resistance device and a clutch device are connected via a first traction assembly and a second traction assembly, respectively. The first traction assembly includes a control cable connecting to the control handle and an execution cable connecting to the resistance device; the second traction assembly includes a control cable connecting to the control handle and an execution cable connecting to the clutch device. The treadmill also includes a wiring module, wherein the control cable and execution cable of the first traction assembly are respectively connected to the first control reel 121 and the first execution reel 221, and the control cable and execution cable of the second traction assembly are respectively connected to the second control reel 122 and the second execution reel 222.

[0052] Therefore, this technical solution replaces traditional fixed wiring with detachable connections through a modular wiring design, eliminates assembly deviations using a linkage structure, and achieves independent control of multi-path traction through a double-layer cable reel. During transportation, the cable is separated from the main body, reducing volume. During assembly, the cable position is automatically calibrated through mechanical linkage, fundamentally solving the transmission failure problems caused by misalignment and difficulty in adjusting tension in traditional solutions. During assembly, only the first unit 1 and the second unit 2 need to be fixed together and the locking pin removed; the linkage structure automatically ensures synchronous alignment of the cable reels, avoiding manual threading errors. In use, the double-layer cable reel structure independently controls two traction systems, the linkage structure ensures transmission synchronization, and the locking pin removal mechanism ensures free rotation after docking. This design effectively solves...

[0053] This addresses the technical problems of traditional treadmill traction components, such as difficulties in cable separation during transportation and assembly, complex installation, and susceptibility to transmission failure.
