Description

Technical Field

[0001] The present invention relates to the technical field of fitness equipment, and in particular to an adjustment handle of fitness equipment. Background Art

[0002] In recent years, unpowered treadmills have attracted widespread attention due to their characteristics of not requiring external power and relying on the user's own motion drive. In the prior art, as Chinese invention patent CN117942527A discloses a unpowered treadmill, which realizes resistance adjustment by arranging a magnetic resistance device and a clutch wheel structure on the frame. However, this solution has the following shortcomings: the resistance adjustment handle and the clutch handle usually adopt a split design, which are independently arranged at the upper ends of two columns, causing the user to need to operate the two handles with their left and right hands respectively to complete the clutch combination and resistance adjustment. This design has obvious cumbersome operation problems, especially when quickly switching the motion mode, the user needs to frequently switch the operation target, which seriously affects the user experience. In addition, the separate handles need to be equipped with independent transmission components and positioning mechanisms, which not only increases the complexity and manufacturing cost of the overall structure, but also causes the increase of potential failure points, and the maintenance difficulty is significantly improved.

[0003] In view of the above problems, the existing technology is in urgent need of improvement. Summary of the Invention

[0004] In order to solve the above problems, the purpose of the present invention is to provide an adjustment handle for fitness equipment, which has the advantages of simple operation, compact structure, high functional integration and convenient maintenance.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0006] The present application provides a fitness equipment adjustment handle, the technical solution of which is as follows: it includes a positioning seat fixed to the upper end of the column of the fitness equipment. The handle body is rotatably arranged at the axial center position of the positioning seat through a central pivot, and a circumferential positioning mechanism is provided between the handle body and the positioning seat. The clutch control disk and the resistance control disk are arranged along the axial direction of the central pivot, the clutch control disk is configured to pull the clutch control cable, and the resistance control disk is configured to connect the resistance control cable and form a circumferential linkage with the handle body. The clutch control mechanism is provided in the handle body, and the clutch control mechanism selectively causes the handle body to form a circumferential linkage or disengagement with the clutch control disk.

[0007] Technical features include: a locating seat that secures the handle's overall structure; the handle's main body pivots to achieve rotation; a circumferential positioning mechanism locks the handle's main body and locating seat relative to each other; a clutch control dial and a resistance control dial independently control the clutch and resistance functions; and a clutch control mechanism that switches the clutch and clutch control dials in tandem. These features work together to integrate both control functions into a single handle through the axially arranged clutch and resistance control dials; the clutch control mechanism enables mode selection through mechanical linkage; and the circumferential positioning mechanism ensures positional stability during adjustment.

[0008] This solution utilizes structural integration and linkage design to enable a single handle to simultaneously perform clutch control and resistance adjustment functions. As the handle rotates, the clutch control mechanism selects and engages the clutch control dial (implementing clutch operation). The handle remains in constant contact with the resistance control dial, enabling resistance adjustment. A circumferential positioning mechanism ensures precise positioning during resistance adjustment, enabling the selection of different resistance levels. This design avoids the cumbersome operation of separate handles and simplifies the transmission structure.

[0009] Furthermore, the present application also proposes that the positioning seat includes a positioning disk, and a plurality of positioning holes are arranged circumferentially on the disk surface of the positioning disk. The circumferential positioning mechanism includes at least one group of spring pin assemblies provided on the handle body, and the output end of the spring pin assembly is elastically pressed against the positioning disk and can be snapped into one of the positioning holes to achieve circumferential positioning. The circumferentially arranged positioning holes provided on the positioning disk cooperate with the spring pin assemblies on the handle body, and the reliable circumferential positioning of the handle body relative to the positioning seat is achieved through the elastic pressing of the spring pin assemblies and the action of snapping into the positioning holes. This structural design enables the handle to accurately stay at a preset angle position when rotating, while ensuring the stability of positioning and the convenience of operation through the elastic snap-in method.

[0010] The elastic pressure-resistance characteristic of the spring pin assembly not only ensures the reliability of positioning, but also allows the user to overcome the elastic force to adjust the angle when applying a certain rotational force, thus achieving the dual functions of positioning and adjustment.

[0011] Furthermore, the present application also proposes that the circumferential positioning mechanism also includes a mounting plate fixed to the handle body, and a plurality of hollow sleeves are constructed on the surface of the mounting plate. The spring pin assembly is installed in the hollow sleeve, and the steel ball of the spring pin assembly can be exposed or retracted from the end portion of the hollow sleeve, thereby elastically pressing against the positioning plate. The mounting plate is fixed to the handle body to provide a rigid support base; the hollow sleeve is constructed on the surface of the mounting plate to form an axial guide channel; the spring pin assembly is embedded in the hollow sleeve, and the radial displacement is limited by the sleeve; the steel ball is retractably exposed from the end of the sleeve to achieve elastic positioning contact. These features work together: the mounting plate and the hollow sleeve form a stable mounting structure to ensure the axial centering of the spring pin assembly; the inner wall of the sleeve constrains the movement trajectory of the spring pin assembly to avoid lateral shaking; the retractable design of the steel ball maintains a continuous pressure force on the positioning plate, while allowing sliding transition during circumferential adjustment.

[0012] This solution changes the spring pin assembly from direct cantilever installation to axial embedded fixation by adding an integrated structure of a mounting plate and a hollow shaft sleeve, significantly improving the structural stability of the assembly during frequent adjustments. At the same time, the hollow shaft sleeve precisely guides the movement trajectory of the steel ball, ensuring uniform pressure distribution on the positioning contact surface and avoiding positioning failure caused by local wear.

[0013] Furthermore, the present application also proposes that the clutch control disk is arranged between the mounting disk and the positioning disk. The clutch control disk is constructed with an arc-shaped through hole, and the hollow sleeve on the mounting disk passes through the arc-shaped through hole, and enables the steel ball of the spring pin assembly to elastically press against the positioning disk. The clutch control disk is arranged axially between the mounting disk and the positioning disk; the clutch control disk is provided with an arc-shaped through hole for the hollow sleeve to pass through; the spring pin assembly realizes the elastic pressing of the steel ball against the positioning disk through the hollow sleeve. These features work together: the axial arrangement optimizes space utilization and avoids interference between components; the arc-shaped through hole provides a movable channel for the hollow sleeve to ensure the relative rotational freedom between the mounting disk and the clutch control disk; the steel ball continuously presses against the positioning disk to maintain circumferential positioning stability, while allowing the handle body to drive the clutch control disk to rotate synchronously during adjustment.

[0014] Through a layered structural design, the clutch control disc is integrated between the mounting disc and the positioning disc. The use of through-holes and bushings allows for a compact multi-component layout, ensuring independent operating space for the clutch function while maintaining the mechanical reliability of the overall structure. This solution enables conflict-free coordination between the clutch control disc and the circumferential positioning mechanism within a limited space.

[0015] Furthermore, the present application also proposes that the clutch control disk and the resistance control disk are respectively arranged on both sides of the positioning disk. The central pivot passes through the central hole of the positioning disk and the central hole of the clutch control disk, and the two ends are respectively fixedly connected to the handle body and the resistance control disk. The clutch control disk and the resistance control disk are respectively arranged on both sides of the positioning disk. Through this arrangement, the two control disks are separated in the axial space to avoid mutual interference. The central pivot passes through the central hole of the positioning disk and the central hole of the clutch control disk, and is fixedly connected to the handle body and the resistance control disk. This connection method ensures that the handle body, the clutch control disk and the resistance control disk can rotate around the same axis, and the central pivot ensures that the handle body and the resistance control disk are always fixedly linked, while maintaining structural stability and transmission efficiency. Through this arrangement and connection method, the technical problems of the axial arrangement of the double disks and the central pivot connection are solved, and a compact structure and functional integration are achieved.

[0016] Furthermore, the present application also proposes that the clutch control mechanism includes a control block that is radially movable and arranged in the handle body, and a drive assembly and a return spring for driving the control block to move radially. A slot is provided on the clutch control disk. When the control block is embedded in the slot, the handle body and the clutch control disk are circumferentially linked. When the control block exits the slot, the handle body and the clutch control disk are disengaged. The control block is radially movable and arranged in the handle body. The drive assembly and the return spring drive the control block to move. A slot is provided on the clutch control disk. The control block is embedded in the slot to achieve linkage, and exits the slot to release the linkage. These features work synergistically: the drive assembly provides active driving force to move the control block radially, and the return spring provides reset force; the cooperation between the slot and the control block achieves mechanical interlocking to ensure the stability of the linkage state; the radially movable design makes the switching action reliable and takes up little space. This solution achieves reliable switching between the two states through a mechanical interlocking structure, solving the problem of cumbersome operation of traditional split handles.

[0017] Furthermore, the present application also proposes that the clutch control mechanism also includes a movable plate, and a movable groove and a spring groove are constructed on the inner wall of the handle body. The movable plate is installed in the movable groove, the upper end cooperates with the drive assembly, and the lower end is fixed to the control block. The reset spring is embedded in the spring groove and its output end is supported on the movable plate. A cover plate is provided on the inner wall of the handle body, and the output end of the control block passes through the strip hole on the cover plate. The cooperation between the movable groove and the movable plate constrains the movement trajectory of the movable plate, ensuring that the control block only moves radially; the combination of the spring groove and the reset spring provides an automatic reset function, so that the control block returns to its initial position after the external force is removed; the design of the cover plate and the strip hole not only limits the movement range of the control block, but also ensures that its output end is reliably engaged with the card slot of the clutch control disk. The above structure realizes high-precision and repeatable operation of the clutch control mechanism by combining mechanical limiting and elastic reset.

[0018] Furthermore, the present application proposes that a grip is provided at the top of the handle body. The drive assembly includes a button movably disposed within the grip. The end of the button extends beyond the end of the grip, serving as a force-applying end, and engages with the top bevel of the movable plate. When external force is applied to the button, the movable plate is pressed radially inward. When the external force is removed, a return spring drives the movable plate radially outward and ejects the button. The grip serves as a load-bearing component for single-handed operation; the button is integrated within the grip to enable pressing operation while gripping; the beveled surface cooperates to convert axial pressing force into radial movement of the movable plate; and the return spring provides an automatic reset function. These features work synergistically: when the user presses the button at the end of the grip, the clutch control mechanism is activated via the beveled surface. When the button is released, the return spring pushes the movable plate back to its original position and simultaneously causes the button to rebound, completing the single-handed operation cycle. This solution highly integrates the drive assembly within the grip, eliminating additional operating components and simplifying the operation process.

[0019] Furthermore, the present application proposes that the positioning seat also includes a panel disposed on at least one axial end edge of the positioning disc, with a chamber formed between the panel and the positioning disc for mounting the clutch control disc and / or the resistance control disc. The panel is provided with a locking hole and a resistance adjustment sliding hole. The control block is also provided with a protrusion. When in the unadjusted state, the control block's protrusion engages the locking hole, circumferentially locking the handle body and the control block. When adjusting the clutch, the control block engages the slot and the protrusion exits the locking hole, circumferentially interlocking the handle body and the clutch control disc. When adjusting the resistance, the control block exits the slot and the protrusion enters the resistance adjustment sliding hole, disengaging the handle body from the clutch control disc. The handle body then drives the resistance control disc to rotate and achieves circumferential positioning relative to the positioning disc using a circumferential positioning mechanism. The chamber formed by the panel and the positioning disc provides integrated mounting space for the clutch control disc and the resistance control disc, reducing structural fragmentation. The locking hole and the protrusion cooperate to achieve circumferential mechanical locking in the unadjusted state, preventing misoperation. The resistance adjustment sliding hole and protrusion cooperate to provide a guide limit in resistance adjustment mode, ensuring stability during rotation of the resistance control dial. The resistance adjustment sliding hole also provides space for the protrusion to move after the spring force resets. The control block's position switching logic between three states (engaging in the locking hole / embedding in the slot / entering the sliding hole) allows for single-handed switching between clutch adjustment, resistance adjustment, and locking, streamlining the operation process. The synergistic effect of the circumferential positioning mechanism and the resistance adjustment sliding hole ensures precise positioning during resistance adjustment.

[0020] This solution integrates clutch control, resistance adjustment, and locking functions into a single operational flow through the integrated design of a mechanical interlocking structure and a motion-guided mechanism. The cavity formed by the enclosure optimizes space utilization, while the dedicated design of the locking and sliding holes enables precise switching between functional modes. The three-position change of the protrusion is the core execution unit for integrated operation. This design significantly improves operational efficiency and reduces structural complexity while ensuring functional reliability.

[0021] Furthermore, the present application also proposes that it also includes an auxiliary locking assembly: the auxiliary locking assembly includes a base fixed on the positioning seat, and a positioning block and a positioning spring arranged in the positioning seat. A positioning through-hole is provided on the clutch control disk, and a slider is provided in the positioning through-hole. The positioning block is pressed against the clutch control disk under the action of the positioning spring, and only when the clutch control disk is adjusted to the engaged state, the positioning through-hole moves to align with the positioning block, the positioning block is stuck in the positioning through-hole and pushes the slider. When the engaged state needs to be released, the operating control block is pressed into the slot, the handle body is circumferentially linked with the clutch control disk, and at the same time, the control block pushes the slider to push the positioning block out of the positioning through-hole.

[0022] The auxiliary locking assembly is fixed to the positioning seat via a base, providing a mounting foundation for the positioning block. The positioning block cooperates with the positioning spring to form an elastic pressure force against the clutch control disk. The positioning hole on the clutch control disk and the slider form a positioning and matching structure. When the clutch control disk rotates to the engaged position, the positioning hole and the positioning block automatically align. The positioning block, under the action of the spring force, engages the hole and pushes the slider, achieving mechanical locking. This limits the clutch control disk from producing circumferential deflection under the different tensions of the two clutch ropes. When the engaged state is released, the control block simultaneously drives the slider to push out the positioning block, achieving linked unlocking. This solution enhances the positioning reliability of the engaged state through a mechanical interlocking structure while maintaining the convenience of the unlocking operation.

[0023] This technical solution adds a secondary positioning function to the existing clutch control mechanism by adding an auxiliary locking component. When the clutch control dial is rotated to the engaged position, the positioning block and the positioning hole form a mechanical interlock, preventing accidental disengagement due to vibration or misoperation. When disengaged, a single operation of the control block simultaneously completes the clutch linkage and positioning release, maintaining the convenience of one-handed operation. This design improves operating stability while maintaining ease of operation, and solves the problem of unstable clutch positioning in the integrated handle.

[0024] From the above, it can be seen that the present application provides a fitness equipment adjustment handle and its clutch control and resistance adjustment integrated structure, which integrates the clutch control and resistance adjustment functions into a single handle, and adopts a central pivot to cooperate with a circumferential positioning mechanism to realize multi-function switching, thereby solving the problems of cumbersome operation and complex structure in the prior art, and has the advantages of simple operation, compact structure, high functional integration and easy maintenance.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more, unless otherwise explicitly specified.

[0035] In the present invention, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections. They may refer to mechanical connections or electrical connections.

[0037] like Figure 1-7 As shown, this embodiment relates to an adjustment handle of fitness equipment, comprising:

[0038] - Positioning seat 1, fixed to the upper end of the column 8 or the armrest 9 of the fitness equipment;

[0039] - A handle body 2 is rotatably mounted on the axial center of the positioning seat 1 via a central pivot 3, with a circumferential positioning mechanism provided between the handle body 2 and the positioning seat 1;

[0040] - A clutch control disc 4 and a resistance control disc 5 are arranged axially along the central pivot 3, the clutch control disc 4 is configured to pull a clutch control cable 41, and the resistance control disc 5 is configured to connect a resistance control cable 51 and form a circumferential linkage with the handle body 2;

[0041] A clutch control mechanism is provided in the handle body 2, which selectively enables the handle body 2 and the clutch control disk 4 to form a circumferential linkage or disengagement.

[0042] The positioning base 1 can be made of metal casting or engineering plastic injection molding, and its connection to the column 8 can be bolted, welded, snap-fitted, or integrally molded. The central pivot 3 is preferably made of stainless steel. On the one hand, it is fixedly connected to the handle body 2 and the resistance control disk 5 to achieve linkage between the three. On the other hand, it is rotatably connected to the positioning base 1 and the clutch control disk 4 through a bearing or sleeve.

[0043] This technical solution integrates the functions of a traditional split handle into a single operating unit through the axially arranged clutch control disc 4 and resistance control disc 5. As the handle body 2 rotates, the clutch control mechanism engages or disengages with the clutch control disc 4 according to operational requirements. In the engaged state, the clutch control cable 41 is pulled to achieve transmission engagement. In the engaged state, the handle body 2 controls the resistance control disc 5 to adjust the resistance parameter. In this solution, the resistance control disc 5 forms a circumferential linkage with the handle body 2, rotating synchronously at all times. That is, when the clutch control mechanism engages with the clutch control disc 4, i.e., during clutch adjustment, the resistance control disc 5 also rotates synchronously, as long as it is at the end of the resistance actuation path, such as when the adjustment path of the magnetic resistance device is accounted for. A circumferential positioning mechanism ensures the handle's positional stability during rotational adjustment, preventing accidental shifting. Compared to existing technologies, this design reduces the number of operational steps and components, reducing assembly complexity. Furthermore, the mechanical linkage structure improves the reliability of mode switching, resolving the technical issue of cumbersome operation with split handles.

[0044] Further, if Figure 4 and 7 As shown in FIG, two clutch control cables 41 are provided, both connected to the clutch control disk 4, for controlling the forward and backward movement of the clutch disk. A single resistance control cable 51 is provided, connected to the resistance control disk 5. When the resistance control disk 5 pulls the resistance control cable 51, the magnetic resistance device is brought closer to the flywheel. When the resistance control cable 51 is released, the magnetic resistance device is reset by a spring on the magnetic resistance device.

[0045] In a specific embodiment, the positioning seat 1 includes a positioning disk 101, the surface of which is circumferentially arranged with a plurality of positioning holes 102. The circumferential positioning mechanism includes at least one set of spring pin assemblies 201 disposed on the handle body 2. The output end of the spring pin assembly 201 elastically presses against the positioning disk 101 and can snap into one of the positioning holes 102 to achieve circumferential positioning. This technical solution achieves circumferential positioning through an elastic snap-fit structure. Its working principle is that the evenly distributed positioning holes 102 on the positioning disk 101 cooperate with the elastic snap-fit action of the spring pin assembly 201, allowing the handle body 2 to be positioned in stages during rotation. The elastic pressing properties of the spring pin assembly 201 ensure close contact between the steel ball and the positioning hole 102 during positioning while allowing the user to overcome the elastic force and switch gears when applying a rotational force. Compared to the prior art methods of threaded locking or latch fixing, this solution offers the advantage of ease of operation; positioning and adjustment can be completed by rotating the handle with one hand. At the same time, the elastic snap-fit structure prevents positioning failure caused by mechanical wear, improving reliability over long-term use.

[0046] In an practicable solution, the spring pin assembly 201 may be implemented in the following manner:

[0047] The spring pin assembly 201 consists of a pin shaft, a compression spring, and a steel ball. The pin shaft contains a spring cavity, with the compression spring preloaded between the steel ball and the bottom of the cavity. The steel ball partially protrudes from the end of the pin shaft. As the handle body 2 rotates, the steel ball is squeezed back into the spring cavity by the surface of the positioning plate 101, accumulating elastic force in the compression spring. When the steel ball aligns with the positioning hole 102, the spring automatically snaps into place, completing the positioning.

[0048] As another embodiment, the spring pin assembly 201 may be an elastic sheet structure, one end of the elastic sheet being fixed to the handle body 2 and the other end being provided with a protrusion which is elastically deformed to fit into the positioning hole 102;

[0049] - In addition, the positioning hole 102 can be designed as a tapered hole or a stepped hole to enhance the matching stability with the steel ball / protrusion.

[0050] In the embodiment shown in the figure, the circumferential positioning mechanism also includes a mounting plate 202 fixed to the handle body 2. Several hollow sleeves 203 are constructed on the surface of the mounting plate 202. A spring pin assembly 201 is mounted within the hollow sleeve 203, and the steel ball of the spring pin assembly 201 can be exposed or retracted from the end portion of the hollow sleeve 203, thereby elastically pressing against the positioning plate 101. The mounting plate 202 can be formed of a metal stamping or injection-molded engineering plastic. Its connection to the handle body 2 can be achieved by, but not limited to, bolting, welding, or a snap-fit connection. The hollow sleeve 203 is preferably a tubular structure integrally formed with the mounting plate 202. The inner diameter of the sleeve forms a clearance fit with the outer diameter of the spring pin assembly 201. The clearance is controlled within the range of 0.05-0.2 mm to ensure smooth axial sliding. The extension and retraction travel of the steel ball is limited by a constriction at the end of the hollow sleeve 203. The constriction diameter is smaller than the diameter of the steel ball but larger than the projected diameter of the exposed portion of the steel ball. As an alternative, the hollow sleeve 203 can be designed as a split structure, consisting of a sleeve body and a limit ring connected by threads, which facilitates the adjustment of the initial pressure of the steel ball. This technical solution changes the spring pin assembly 201 from a cantilever installation to an axial embedded fixation through the coordinated design of the mounting plate 202 and the hollow sleeve 203. The mounting plate 202 provides a rigid support platform, and the hollow sleeve 203 forms a precise axial guide channel, effectively restraining the radial deviation of the spring pin assembly 201. The retractable design of the steel ball at the end of the hollow sleeve 203 not only maintains continuous elastic pressure on the positioning plate 101, but also allows a smooth transition during circumferential adjustment. Compared with the solution in the prior art in which the spring pin is directly fixed to the handle body 2, this structure significantly reduces the radial swing amplitude of the assembly during frequent operation. At the same time, the precise guidance of the hollow sleeve 203 on the movement trajectory of the steel ball makes the pressure distribution on the positioning contact surface uniform, effectively avoiding the wear problem caused by local stress concentration.

[0051] like Figure 2-5As shown, the clutch control disk 4 is arranged between the mounting disk 202 and the positioning disk 101. A circular arc-shaped through hole 401 is constructed on the clutch control disk 4, and the hollow sleeve 203 on the mounting disk 202 passes through the circular arc-shaped through hole 401, and the steel ball of the spring pin assembly 201 is elastically pressed against the positioning disk 101. Specifically, the clutch control disk 4 is located in the axial gap between the mounting disk 202 and the positioning disk 101, and the size of the axial gap is configured to allow the clutch control disk 4 to maintain a stable position in the axial direction without affecting the relative movement of the mounting disk 202 and the positioning disk 101. The arc range of the circular arc-shaped through hole 401 is determined according to the motion trajectory of the hollow sleeve 203, and the width of the through hole is slightly larger than the outer diameter of the hollow sleeve 203 to provide a rotational clearance. As a preferred embodiment, the circular arc-shaped through hole 401 can be set as a concentric arc, the center of which is coaxial with the central pivot 3, so as to ensure the smooth movement of the hollow sleeve 203 in the through hole. Furthermore, the steel ball of the spring pin assembly 201 maintains continuous pressure against the positioning disk 101 through the preload of the spring inside the hollow sleeve 203. The pressure is configured to maintain circumferential positioning stability while allowing the handle body 2 to drive the clutch control disk 4 to overcome friction and achieve synchronous rotation during adjustment. Thus, this technical solution achieves space optimization through axial layered arrangement, and the laminated structure of the clutch control disk 4, the mounting disk 202, and the positioning disk 101 avoids radial interference between components. The arc-shaped through-hole 401 provides a directional movement channel for the hollow sleeve 203, ensuring the relative rotational freedom of the mounting disk 202 and the clutch control disk 4. The elastic pressure mechanism of the steel ball maintains positioning accuracy while allowing moderate flexible deformation during operation. Compared with the existing technology, this solution, through structural integration design, simultaneously realizes the coordinated operation of the clutch control function and the circumferential positioning function in a limited space, solves the technical difficulties of spatial layout and linkage coordination of multiple components, and has the advantages of compact structure, reliable operation, and easy maintenance.

[0052] Furthermore, the clutch control disc 4 and the resistance control disc 5 are respectively disposed on either side of the positioning disc 101. The central pivot 3 passes through the center hole of the positioning disc 101 and the center hole of the clutch control disc 4, and is respectively affixed to the handle body 2 and the resistance control disc 5 at both ends. Specifically, the clutch control disc 4 and the resistance control disc 5 are respectively disposed on either side of the positioning disc 101, wherein the center hole of the positioning disc 101 is used to accommodate the central pivot 3. The central pivot 3 passes through the center hole of the positioning disc 101 and the center hole of the clutch control disc 4, and is respectively affixed to the handle body 2 and the resistance control disc 5 at both ends. As a preferred embodiment, the central pivot 3 can be affixed to the handle body 2 and the resistance control disc 5 by threaded connection, welding, or keyway fitting. The center hole of the clutch control disc 4 can be configured to have a clearance fit or a bearing fit with the central pivot 3 to ensure that the clutch control disc 4 can rotate circumferentially relative to the central pivot 3. The resistance control disc 5 can further be affixed to the central pivot 3 by pinning or flange connection to ensure synchronous rotation. Thus, this technical solution achieves the separation of the two control disks in the axial space by arranging the clutch control disk 4 and the resistance control disk 5 on both sides of the positioning disk 101, thereby avoiding mutual interference. The central pivot 3 passes through the positioning disk 101 and the clutch control disk 4 and is fixed to the handle body 2 and the resistance control disk 5, ensuring that the handle body 2, the clutch control disk 4 and the resistance control disk 5 can rotate around the same axis. Through this arrangement and connection method, the technical problems of the axial arrangement of the two disks and the central pivot connection are solved, and a compact structure and functional integration are achieved. Compared with the existing technology, this solution realizes the linkage and positioning of multiple functional components through a single central pivot 3, simplifies the structure, and improves the transmission efficiency and operational stability.

[0053] like Figure 3 and 5As shown, the clutch control mechanism includes a control block 601 radially movable within the handle body 2, a drive assembly and a return spring 603 for driving radial movement of the control block 601. The clutch control disc 4 is provided with a slot 402. When the control block 601 is inserted into the slot 402, the handle body 2 and clutch control disc 4 engage in circumferential interlocking motion. When the control block 601 exits the slot 402, the handle body 2 and clutch control disc 4 disengage from each other. The control block 601 can have a cylindrical, rectangular, or irregular cross-section. Its radial movement is precisely positioned using guide grooves or slide rails. The drive assembly can be button-type, lever-type, or electromagnetic. The button-type drive converts axial pressure into radial displacement through an inclined surface mechanism, as detailed below. The return spring 603 is preferably a cylindrical coil spring, but can also be a disc spring or elastic sheet structure. The slot 402 is designed as a groove that matches the shape of the control block 601. The depth should ensure that it can withstand circumferential torque after insertion. The groove wall can be provided with a wear-resistant coating. This solution achieves reliable switching of the linkage state through a mechanical interlocking structure. The drive assembly applies radial force to embed the control block 601 into the slot 402, forming a rigid connection to transmit torque. The return spring 603 provides a reverse force to ensure quick disengagement. The radially movable design reduces the axial space occupied and makes the overall structure compact. Compared with the split handle, the integrated design simplifies the operation process, and the clutch switching can be completed with one hand, avoiding the coordination problems of multi-handle operation. The matching precision of the slot 402 and the control block 601 is high, and there is no relative sliding in the linkage state, ensuring the stability of the adjustment. The preload force of the return spring 603 is adjustable, which can adapt to different operating force requirements and enhance the user experience.

[0054] In a specific embodiment, the clutch control mechanism also includes a movable plate 604, and a movable groove 605 and a spring groove 606 are constructed on the inner wall of the handle body 2. The movable plate 604 is installed in the movable groove 605, the upper end cooperates with the drive assembly, and the lower end is fixed to the control block 601. The reset spring 603 is embedded in the spring groove 606 and its output end is supported on the movable plate 604. A cover plate 607 is provided on the inner wall of the handle body 2, and the output end of the control block 601 passes through the strip hole 608 on the cover plate 607. The movable plate 604 can be made of metal stamping or engineering plastic injection molding, and its thickness is matched with the clearance of the movable groove 605 to ensure smooth sliding. The cross-sectional shape of the spring groove 606 matches the outer diameter of the reset spring 603, and a circular or rectangular cross-section can be adopted. A limiting boss can be provided at the bottom of the groove to prevent the spring from falling off. The width of the strip hole 608 of the cover plate 607 is 0.5-1mm larger than the output end of the control block 601, and a 2-3mm movement margin is reserved in the length direction. This technical solution strictly limits the movement of the control block 601 in the radial direction through the precise cooperation of the movable groove 605 and the movable plate 604, thereby avoiding the jamming problem caused by deflection. The reset spring 603 provides a stable reset force to ensure that the control block 601 accurately returns to its initial position after the external force is removed. The matching design of the cover plate 607 and the strip hole 608 not only limits the movement stroke of the control block 601, but also ensures the precise alignment of its output end with the card slot 402 of the clutch control disk 4. The synergistic effect of the mechanical limit structure and the elastic reset mechanism realizes the high-reliability operation of the clutch control mechanism, and solves the problems of unstable motion trajectory and insufficient reset accuracy in the prior art.

[0055] like Figure 3 and 5As shown, a grip 209 is provided at the top of the handle body 2. The drive assembly includes a button 609 movably provided inside the grip 209. The end of the button 609 extends from the end of the grip 209 as a force-applying end, and the button 609 cooperates with the top inclined surface of the movable plate 604. When an external force is applied to the button 609, the movable plate 604 is driven to be pressed radially inward; when the external force is removed, the return spring 603 drives the movable plate 604 to move radially outward and push the button 609 out. The grip 209 adopts a hollow tubular structure, and a guide groove is provided inside to constrain the linear motion trajectory of the button 609. The force-applying end of the button 609 can be set as a hemispherical protrusion or a flat pressing surface, wherein the hemispherical protrusion facilitates finger positioning, and the flat pressing surface increases the contact area and improves operational stability. The inclined surface matching structure preferably adopts a 45° inclination angle to achieve proportional conversion between axial pressing force and radial movement force. This technical solution integrates the drive assembly inside the handle 209 to achieve direct linkage between the natural pressing action of the thumb and the clutch control during one-handed operation. When the button 609 is pressed, the inclined surface structure converts the axial force into the radial displacement of the movable plate 604, pushing the control block 601 to embed in the slot 402 of the clutch control disk 4. After releasing the button 609, the reset spring 603 simultaneously completes the reset of the movable plate 604 and the rebound of the button 609, forming a self-locking operation cycle. Compared with the split operating mechanism in the prior art, this design reduces the operating steps, avoids the need to shift vision, and ensures the synchronization of actions through mechanical linkage. The inclined surface transmission structure reduces component wear while ensuring the operating force, and the bidirectional action of the reset spring 603 simplifies the complexity of the reset mechanism.

[0056] like Figure 6 As shown, the positioning seat 1 also includes a panel 103 disposed on at least one axial end edge of the positioning disc 101. A cavity for mounting the clutch control disc 4 and / or the resistance control disc 5 is formed between the panel 103 and the positioning disc 101. The panel 103 is provided with a locking hole 104 and a resistance adjustment sliding hole 105. The control block 601 is also provided with a protrusion 611. When in the unadjusted state, the protrusion 611 of the control block 601 is stuck in the lock hole 104, and the handle body 2 and the control block 601 are circumferentially locked; when in the clutch adjustment state, the control block 601 is embedded in the slot 402 and the protrusion 611 exits the lock hole 104, and the handle body 2 is circumferentially linked with the clutch control disk 4; when in the resistance adjustment state, the control block 601 exits the slot 402 and the protrusion 611 enters the resistance adjustment sliding hole 105, the handle body 2 is disengaged from the clutch control disk 4, and the handle body 2 drives the resistance control disk 5 to rotate and realizes circumferential positioning relative to the positioning disk 101 based on the circumferential positioning mechanism.

[0057] In this solution, the enclosure 103 can be an annular or partially arc-shaped structure, and its height is determined by the thickness of the clutch control disk 4 and the resistance control disk 5. The lock hole 104 and the resistance adjustment sliding hole 105 are arranged on the same circumferential surface of the enclosure 103. The lock hole 104 is a circular through hole or a rectangular through hole, and the hole diameter is slightly larger than the diameter of the protrusion 611 to achieve precise engagement. The resistance adjustment sliding hole 105 is an arc-shaped long groove, whose curvature matches the rotation trajectory of the handle body 2 and the length meets the resistance adjustment stroke requirements. The protrusion 611 can be a cylindrical pin, a hemispherical structure, or a rectangular protrusion, and is fixed to the radial outer surface of the control block 601 by integral or welding or threading. This technical solution realizes the integrated installation of the clutch control disk 4 and the resistance control disk 5 through the cavity formed by the enclosure 103. The cooperation between the lock hole 104 and the protrusion 611 ensures the mechanical locking stability in the unadjusted state, and the resistance adjustment sliding hole 105 provides motion guidance and limit functions for the resistance adjustment mode. The three-position switching logic of control block 601 enables single-handed operation to switch between clutch adjustment, resistance adjustment, and locked states, significantly simplifying the operational process. Compared to existing split handles, this integrated design reduces the number of components and structural complexity, while also ensuring the reliability of switching between functional modes through a mechanical interlocking structure. The synergistic effect of the circumferential positioning mechanism and the resistance adjustment sliding hole 105 further improves positioning accuracy during resistance adjustment, avoiding the positioning deviation problem caused by cumbersome operation in traditional solutions.

[0058] like Figure 2 and 4As shown in Figure 7, the present application also proposes an auxiliary locking assembly 7, including a base 701 fixed on the positioning seat 1, and a positioning block 702 and a positioning spring 703 arranged in the positioning seat 1. A positioning through-hole 403 is provided on the clutch control disk 4, and a slider 404 is provided in the positioning through-hole 403. The positioning block 702 is pressed against the clutch control disk 4 under the action of the positioning spring 703. Only when the clutch control disk 4 is adjusted to the engaged state, the positioning through-hole 403 moves to align with the positioning block 702, and the positioning block 702 is inserted into the positioning through-hole 403 and pushes the slider 404. When the engaged state needs to be released, the operating control block 601 is pressed into the card slot 402, and the handle body 2 and the clutch control disk 4 are circumferentially linked. At the same time, the control block 601 pushes the slider 404 to push the positioning block 702 out of the positioning through-hole 403. Specifically, the base 701 can be installed on the axial end face of the positioning seat 1 by bolting or welding, and its installation position must ensure that the movement trajectory of the positioning block 702 intersects perpendicularly with the rotation plane of the clutch control disk 4. The positioning block 702 is preferably a cylindrical structure, and a conical guide surface can be provided at its end to reduce the friction resistance when inserted into the positioning through hole 403. The positioning spring 703 can be a helical compression spring, and its preload force must meet the mechanical requirements of being able to reliably press the clutch control disk 4 and be smoothly ejected by the slider 404. The slider 404 can be designed as a T-shaped structure, and a matching inclined surface is provided on the contact surface between its head and the control block 601. This technical solution adds a mechanical interlocking structure, and when the clutch control disk 4 rotates to the engaged position, the positioning block 702 automatically snaps into the positioning through hole 403 to form a rigid limit, effectively preventing accidental disengagement due to vibration or misoperation. The elastic compressive force of the positioning spring 703 ensures that the positioning block 702 maintains contact with the clutch control plate 4, while the linkage design of the slider 404 synchronizes the unlocking operation with the movement of the control block 601. Compared with existing technologies, this solution significantly improves the stability of the engagement state through a two-stage positioning mechanism while maintaining the convenience of one-handed operation, thus solving the problem of unstable positioning caused by uneven tension of the clutch cable in integrated handles.

[0059] The adjustment process of the above fitness equipment adjustment handle is as follows:

[0060] 1. Initial state (unadjusted state)

[0061] -Status Description:

[0062] -The clutch is disengaged (the clutch wheel is not engaged).

[0063] - Resistance is not engaged (resistance control cable is slack and magnetic resistance is away from the flywheel).

[0064] -Operational restrictions:

[0065] -The protrusion on the control block is embedded in the lock hole of the positioning seat panel, and the handle body is circumferentially locked with the positioning seat and cannot rotate.

[0066] 2. Switch to the handle and clutch docking state

[0067] - Press the button:

[0068] Press the button on the top of the grip with your thumb, and the button drives the movable plate to move radially inward through the inclined surface transmission, and the control block retracts and exits the lock hole.

[0069] -Linkage confirmation:

[0070] -The control block is embedded in the slot of the clutch control disk, and the handle body is circumferentially linked with the clutch control disk.

[0071] 3. Adjust to clutch state;

[0072] -Press and hold the button and rotate the handle body until the clutch control dial rotates to the engaged position, where the clutch is just adjusted to the engaged state.

[0073] 4. Lock the clutch and enter resistance adjustment mode

[0074] - Release the button:

[0075] After releasing the thumb, the return spring pushes the movable plate to return to its original position, the control block exits the slot of the clutch control disk, and the handle body is disengaged from the clutch control disk.

[0076] -State switching:

[0077] -Clutch status locked.

[0078] - Resistance adjustment mode activated: The protrusion of the control block exits the lock hole and enters the resistance adjustment sliding hole, and the resistance control disc maintains circumferential linkage with the handle body.

[0079] - Initial resistance level: At this point, the resistance level is at its lowest.

[0080] 5. Adjust the resistance level

[0081] - Rotary gear selection:

[0082] - Turn the handle clockwise (increase resistance): the resistance control disc pulls the resistance control cable, and the magnetic resistance device moves closer to the flywheel.

[0083] - Rotate the handle counterclockwise (to reduce resistance): the resistance control cable relaxes and the magnetic resistance device resets.

[0084] -Gear lock:

[0085] The spring pin assemblies are sequentially inserted into the positioning holes of the positioning plate, and each gear corresponds to a resistance level (a "click" sound and a pause in the handle can be perceived).

[0086] 6. Switch back to clutch adjustment mode

[0087] -Operation prerequisites:

[0088] Rotate the handle to the lowest resistance level (i.e., the clutch engagement position), at which point the protrusion of the control block moves to the end of the resistance adjustment sliding hole.

[0089] - Press the button:

[0090] Press the button on the top of the grip, and the control block will be embedded in the slot of the clutch control disk again, and the handle body and the clutch control disk will be linked circumferentially.

[0091] -Unlock auxiliary lock:

[0092] The control block pushes the slider on the clutch control disk to push the positioning block out of the positioning through hole, thereby releasing the mechanical lock of the clutch state.

[0093] 7. Return to the initial locked state

[0094] -After completing the adjustment:

[0095] Rotate the handle to its initial position, the control block protrusion automatically snaps into the enclosure lock hole, and the handle returns to its unadjusted state.

[0096] -Reset check:

[0097] Confirm that the handle cannot be rotated and the button is fully ejected, indicating that the clutch is disengaged, resistance is not engaged, and all functions have been reset.
