Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to an adjustment handle for fitness equipment. Background Technology

[0002] In recent years, non-powered treadmills have attracted widespread attention due to their characteristic of requiring no external power and relying on the user's own movement for propulsion. Existing technologies, such as the Chinese invention patent CN117942527A, disclose a non-powered treadmill that achieves resistance adjustment by incorporating a magnetic resistance device and a clutch wheel structure on the frame. However, this solution has the following drawbacks: the resistance adjustment handle and the clutch handle are usually designed separately, independently located at the top of two columns, requiring the user to operate two handles with both hands to engage the clutch and adjust the resistance. This design presents a significant operational inconvenience, especially when quickly switching exercise modes, requiring users to frequently switch between target modes, severely impacting the user experience. Furthermore, separate handles require independent transmission components and positioning mechanisms, increasing the overall structural complexity and manufacturing cost, leading to more potential failure points and significantly increasing maintenance difficulty.

[0003] To address the aforementioned issues, existing technologies urgently need improvement. Summary of the Invention

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

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This application provides an adjustable handle for fitness equipment, with the following technical solution: It includes a positioning base fixed to the upper end of the fitness equipment's column. A handle body is rotatably positioned at the axial center of the positioning base via a central pivot, and a circumferential positioning mechanism is provided between the handle body and the positioning base. A clutch control disc and a resistance control disc are arranged axially along the central pivot; the clutch control disc is configured to engage the clutch control cable, and the resistance control disc is configured to connect the resistance control cable and form a circumferential linkage with the handle body. A clutch control mechanism is located within the handle body, selectively causing the handle body to form or disengage circumferential linkage with the clutch control disc.

[0007] The technical features include: the positioning seat is used to fix the overall structure of the handle; the handle body realizes the rotation function through the central pivot; the circumferential positioning mechanism realizes the relative position locking between the handle body and the positioning seat; the clutch control disc and the resistance control disc independently control the clutch and resistance functions respectively; the clutch control mechanism realizes the linkage switching between the handle body and the clutch control disc. These features work together: through the axially arranged clutch control disc and resistance control disc, the two control functions are integrated into a single handle; the clutch control mechanism realizes mode selection through mechanical linkage switching; the circumferential positioning mechanism ensures the position stability during the adjustment process.

[0008] This solution enables a single handle to have both clutch control and resistance adjustment functions through structural integration and linkage design. When the handle body rotates, it is selected to be linked with the clutch control disc (to realize clutch operation) through the clutch control mechanism; and the handle body is always linked with the resistance control disc, so as to realize resistance adjustment, and the circumferential positioning mechanism ensures the positioning accuracy during the resistance adjustment process, so as to realize the selection of different resistance gears. This design avoids the cumbersome operation problem of the split handle and simplifies the transmission structure.

[0009] Furthermore, this application also proposes that the positioning seat includes a positioning disc, and a plurality of positioning holes are arranged circumferentially on the disc surface of the positioning disc. The circumferential positioning mechanism includes at least one set of spring pin assemblies arranged on the handle body, and the output end of the spring pin assembly elastically presses against the positioning disc and can be inserted into one of the positioning holes to achieve circumferential positioning. The circumferentially arranged positioning holes on the positioning disc cooperate with the spring pin assemblies on the handle body. Through the elastic pressing of the spring pin assemblies and the action of inserting into the positioning holes, reliable circumferential positioning of the handle body relative to the positioning seat is achieved. This structural design enables the handle to accurately stop at a preset angular position when rotating, and at the same time ensures the stability of positioning and the convenience of operation through the elastic insertion method.

[0010] The elastic pressing 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, realizing the dual functions of positioning and adjustment.

[0011] Furthermore, this application proposes that the circumferential positioning mechanism further includes a mounting plate fixed to the handle body, with a plurality of hollow bushings constructed on the surface of the mounting plate. The spring pin assembly is installed in the hollow bushings, and the steel ball of the spring pin assembly can protrude or retract from the end portion of the hollow bushing, thereby elastically pressing against the positioning plate. The mounting plate is fixed to the handle body, providing a rigid support base; the hollow bushings are constructed on the surface of the mounting plate, forming an axial guide channel; the spring pin assembly is embedded in the hollow bushing, limiting radial offset through the bushing; the steel ball is retractably exposed at the end of the bushing, achieving elastic positioning contact. These features work synergistically: the mounting plate and the hollow bushing form a stable mounting structure, ensuring the axial alignment of the spring pin assembly; the inner wall of the bushing constrains the movement trajectory of the spring pin assembly, avoiding lateral swaying; the retractable design of the steel ball maintains continuous pressure on the positioning plate while allowing sliding transitions during circumferential adjustment.

[0012] This solution improves the structural stability of the spring pin assembly by adding an integrated structure of the mounting plate and the hollow bushing, changing the spring pin assembly from direct cantilever mounting to axial embedded fixing. At the same time, the hollow bushing accurately 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, this application proposes that the clutch control disc is disposed between the mounting plate and the positioning plate. The clutch control disc has an arc-shaped through hole through which a hollow bushing on the mounting plate passes, causing the steel ball of the spring pin assembly to elastically press against the positioning plate. The clutch control disc is axially arranged between the mounting plate and the positioning plate; the clutch control disc has an arc-shaped through hole for the hollow bushing to pass through; the spring pin assembly uses the hollow bushing to achieve elastic pressure of the steel ball against the positioning plate. These features work synergistically: the axial arrangement optimizes space utilization and avoids component interference; the arc-shaped through hole provides a channel for the hollow bushing to move, ensuring relative rotational freedom between the mounting plate and the clutch control disc; the continuous pressure of the steel ball against the positioning plate maintains circumferential positioning stability, while allowing the handle body to drive the clutch control disc to rotate synchronously during adjustment.

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

[0015] Furthermore, this application proposes that the clutch control disc and the resistance control disc are respectively disposed on both sides of the positioning disc. The central pivot passes through the central hole of the positioning disc and the central hole of the clutch control disc, and its two ends are respectively fixedly connected to the handle body and the resistance control disc. The clutch control disc and the resistance control disc are respectively disposed on both sides of the positioning disc. This arrangement achieves axial separation of the two control discs, avoiding mutual interference. The central pivot passes through the central hole of the positioning disc and the central hole of the clutch control disc, and is fixedly connected to the handle body and the resistance control disc. This connection method ensures that the handle body, clutch control disc, and resistance control disc can rotate around the same axis, and that the central pivot ensures that the handle body and the resistance control disc are always fixedly linked, while maintaining structural stability and transmission efficiency. This arrangement and connection method solves the technical problems of axial arrangement of the two discs and central pivot connection, achieving a compact structure and functional integration.

[0016] Furthermore, this application proposes that the clutch control mechanism includes a control block radially movable within the handle body, and a drive assembly and a return spring for driving the radial movement of the control block. The clutch control disc has a slot; when the control block is inserted into the slot, the handle body and the clutch control disc are circumferentially linked. When the control block exits the slot, the handle body and the clutch control disc are disengaged. The control block is radially movable within the handle body, and the drive assembly and return spring drive the control block to move. The clutch control disc has a slot. Insertion of the control block into the slot achieves linkage, and exiting the slot disengages the linkage. These features work synergistically: the drive assembly provides active driving force to move the control block radially, and the return spring provides a restoring force; the cooperation between the slot and the control block achieves mechanical interlocking, ensuring stable linkage; the radially movable design makes the switching action reliable and space-saving. This solution achieves reliable switching between two states through a mechanical interlock structure, solving the problem of cumbersome operation of traditional split-type handles.

[0017] Furthermore, this application proposes that the clutch control mechanism also includes a movable plate, with a movable groove and a spring groove constructed on the inner wall of the handle body. The movable plate is installed in the movable groove, with its upper end cooperating with the drive assembly and its lower end fixed to the control block. The return spring is embedded in the spring groove, and its output end rests 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 a slotted hole in 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 moves only radially; the combination of the spring groove and the return spring provides an automatic reset function, allowing the control block to return to its initial position after the external force is removed; the design of the cover plate and the slotted hole not only limits the movement range of the control block but also ensures that its output end reliably engages with the slot of the clutch control disc. The above structure achieves high precision and repeatable operation of the clutch control mechanism through a combination of mechanical limiting and elastic reset.

[0018] Furthermore, this application also proposes that a grip bar is provided at the top of the handle body. The drive assembly includes a button movably disposed inside the grip bar. The end of the button extends from the end of the grip bar as a force-applying end, and the button engages with the top inclined surface of the movable plate. When an external force is applied to the button, the movable plate is driven to press radially inward. When the external force is removed, a return spring drives the movable plate to move radially outward and pushes the button out. The grip bar serves as a force-bearing component for one-handed operation; the button is integrated inside the grip bar to enable pressing operation while holding the grip; the inclined surface engagement structure converts axial pressing force into radial movement of the movable plate; and the return spring provides an automatic reset function. The above features work together to achieve: by pressing the button at the end of the grip bar, the user drives the clutch control mechanism to actuate via the inclined surface transmission; after releasing the button, the return spring pushes the movable plate to reset and simultaneously causes the button to spring back, completing the one-handed operation cycle. This solution highly integrates the drive assembly into the grip bar, avoiding additional operating parts and simplifying the operation process.

[0019] Furthermore, this application proposes that the positioning seat also includes a surrounding plate disposed on at least one axial end face edge of the positioning disk, forming a chamber between the surrounding plate and the positioning disk for mounting the clutch control disk and / or the resistance control disk. The surrounding plate is provided with a locking hole and a resistance adjustment sliding hole. The control block is also provided with a protrusion. In the unadjusted state, the protrusion of the control block engages in the locking hole, and the handle body and the control block are circumferentially locked. In the clutch adjustment state, the control block is inserted into the locking slot and the protrusion exits the locking hole, and the handle body is circumferentially linked with the clutch control disk. In the resistance adjustment state, the control block exits the locking slot and the protrusion enters the resistance adjustment sliding hole, the handle body is disengaged from the clutch control disk, and the handle body drives the resistance control disk to rotate and achieve circumferential positioning relative to the positioning disk based on the circumferential positioning mechanism. The chamber formed by the surrounding plate and the positioning disk provides integrated installation space for the clutch control disk and the resistance control disk, reducing structural dispersion. The locking hole and the protrusion cooperate to achieve circumferential mechanical locking in the unadjusted state, preventing accidental operation. The resistance adjustment sliding hole, in conjunction with the protrusion, provides guide and limit functions in resistance adjustment mode, ensuring the stability of the resistance control disc during rotation. The sliding hole also provides space for the protrusion to move after spring-loaded reset. The position switching logic of the control block in three states (engaged in the locking hole / embedded in the slot / entered the sliding hole) allows for single-handed operation to switch between clutch adjustment, resistance adjustment, and locking states, simplifying the operation process. The circumferential positioning mechanism and the resistance adjustment sliding hole work together to ensure positioning accuracy during resistance adjustment.

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

[0021] Furthermore, this application also proposes an auxiliary locking component: the auxiliary locking component includes a base fixed on the positioning seat, and a positioning block and a positioning spring disposed within the positioning seat. The clutch control disc is provided with a positioning through hole, and a slider is disposed within the positioning through hole. The positioning block is pressed against the clutch control disc under the action of the positioning spring. Only when the clutch control disc is adjusted to the engaged state, the positioning through hole moves to align with the positioning block, the positioning block engages in the positioning through hole, and pushes the slider. When it is necessary to disengage, the operating control block is pressed into the slot, the handle body and the clutch control disc are circumferentially linked, and simultaneously the control block pushes the slider to push the positioning block out of the positioning through hole.

[0022] The auxiliary locking component is fixed to the positioning seat via a base, providing an installation foundation for the positioning block. The positioning block cooperates with the positioning spring to form an elastic force that presses against the clutch control disc. The positioning through hole on the clutch control disc and the slider form a positioning engagement structure. When the clutch control disc rotates to the engaged position, the positioning through hole and the positioning block automatically align. Under the action of the spring force, the positioning block engages with the through hole and pushes the slider, achieving mechanical locking. This limits the circumferential deflection of the clutch control disc under the different tensions of the two clutch pull ropes. When disengaging, the control block simultaneously drives the slider to push out the positioning block, achieving linkage unlocking. This solution enhances the positioning reliability of the engaged state through a mechanical interlocking structure while maintaining the convenience of unlocking operations.

[0023] This technical solution adds a secondary positioning function to the original clutch control mechanism by incorporating an auxiliary locking component. When the clutch control disc rotates to the engaged position, the positioning block and the positioning through hole form a mechanical interlock to prevent accidental disengagement due to vibration or misoperation. When disengaging, a single operation of the control block simultaneously completes the clutch engagement and positioning release, maintaining the convenience of one-handed operation. This design improves the stability of the working state while maintaining ease of operation, solving the problem of unstable clutch positioning in integrated handles.

[0024] As can be seen from the above, the fitness equipment adjustment handle and its clutch control and resistance adjustment integrated structure provided by this application integrate clutch control and resistance adjustment functions into a single handle, and use a central pivot and circumferential positioning mechanism to achieve multi-functional switching. This solves 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 convenient maintenance.

[0032] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a mechanical connection or an electrical connection.

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

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

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

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

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

[0042] The positioning seat 1 can be made of metal casting or engineering plastic injection molding, and its connection with the column 8 can be bolted, welded, snap-fitted, or integrally molded. The central pivot 3 is preferably made of stainless steel, which is fixed to the handle body 2 and the resistance control disc 5 to achieve linkage among the three, and is also rotated to the positioning seat 1 and the clutch control disc 4 through bearings or bushings.

[0043] This technical solution integrates the functions of a traditional split handle into a single operating unit through an axially arranged clutch control disc 4 and resistance control disc 5. When the handle body 2 rotates, the clutch control mechanism selects to engage or disengage with the clutch control disc 4 according to operational needs: in the engaged state, the clutch control cable 41 can be pulled to achieve transmission engagement. In the engaged state, the resistance control disc 5 is controlled by the handle body 2 to adjust the resistance parameters. In this solution, the resistance control disc 5 and the handle body 2 form a circumferential linkage, rotating synchronously in the circumferential direction at all times. That is, when the clutch control mechanism selects to engage with the clutch control disc 4, i.e., during clutch adjustment, the resistance control disc 5 also rotates synchronously, as long as this adjustment path is considered at the end of the resistance execution, such as in the adjustment path of a magnetoresistive device. The circumferential positioning mechanism ensures the positional stability of the handle during rotation adjustment, avoiding accidental deviation. Compared with existing technologies, this design reduces the number of operating steps and parts, lowers assembly complexity, and improves the reliability of mode switching through the mechanical linkage structure, solving the technical problem of cumbersome operation of split handles.

[0044] Furthermore, such as Figure 4 and 7 As shown, there are two clutch control cables 41, both connected to the clutch control disc 4, used to control the forward and backward movement of the clutch disc. There is only one resistance control cable 51, connected to the resistance control disc 5. When the resistance control disc 5 pulls the resistance control cable 51, it can bring the magnetic resistance device close to the flywheel. When the resistance control cable 51 is released, it can be reset by the spring on the magnetic resistance device.

[0045] In a specific implementation, the positioning base 1 includes a positioning disk 101, on which multiple positioning holes 102 are arranged circumferentially. 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 engage with one of the positioning holes 102 to achieve circumferential positioning. This technical solution achieves circumferential positioning through an elastic engagement structure. Its working principle is that the evenly distributed positioning holes 102 on the positioning disk 101 cooperate with the elastic engagement action of the spring pin assembly 201, allowing the handle body 2 to be positioned in different gears during rotation. The elastic pressing characteristic of the spring pin assembly 201 ensures close contact between the steel ball and the positioning hole 102 during positioning, and also allows the user to overcome the elastic force to switch gears when applying rotational force. Compared with the existing technology that uses threaded locking or pin fixing, this solution has the advantage of convenient operation, and positioning and adjustment can be completed by rotating the handle with one hand. At the same time, the elastic engagement structure avoids positioning failure caused by mechanical wear, improving the reliability of long-term use.

[0046] In feasible solutions, the spring pin assembly 201 can be implemented in the following ways:

[0047] - The spring pin assembly 201 consists of a pin, a compression spring, and a steel ball. The pin has a spring cavity, and the compression spring is pre-compressed between the steel ball and the bottom of the spring cavity. The steel ball protrudes from the end of the pin. When the handle body 2 rotates, the steel ball is compressed back into the spring cavity by the surface of the positioning disc 101, and the compression spring accumulates elastic force. When the steel ball moves to align with the positioning hole 102, it automatically engages with the positioning hole 102 under the action of the spring, completing the positioning.

[0048] -As another implementation, the spring pin assembly 201 can adopt an elastic sheet structure, with one end of the elastic sheet fixed to the handle body 2 and the other end provided with a protrusion, which is embedded in the positioning hole 102 by elastic deformation.

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

[0050] In the scheme shown in the figure, the circumferential positioning mechanism also includes a mounting plate 202 fixed to the handle body 2, and a plurality of hollow bushings 203 are constructed on the surface of the mounting plate 202. A spring pin assembly 201 is installed in the hollow bushings 203, and the steel ball of the spring pin assembly 201 can protrude or retract from the end portion of the hollow bushing 203, thereby elastically pressing against the positioning plate 101. The mounting plate 202 can be made of metal stamping or injection molding of engineering plastic, and its fixing method with the handle body 2 includes, but is not limited to, bolt connection, welding, or snap-fit ​​fitting. The hollow bushing 203 is preferably a tubular structure integrally formed with the mounting plate 202, and its inner diameter forms a clearance fit with the outer diameter of the spring pin assembly 201, with the clearance controlled within the range of 0.05-0.2mm to ensure smooth axial sliding. The extension and retraction stroke of the steel ball is limited by a constriction structure at the end of the hollow bushing 203, the diameter of which 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 bushing 203 can be designed as a split structure, consisting of a bushing body and a limiting ring connected by threads, facilitating adjustment of the initial pressure of the steel ball. This technical solution, through the coordinated design of the mounting plate 202 and the hollow bushing 203, changes the spring pin assembly 201 from cantilever mounting to axially embedded fixing. The mounting plate 202 provides a rigid support platform, and the hollow bushing 203 forms a precise axial guide channel, effectively constraining the radial offset of the spring pin assembly 201. The telescoping design of the steel ball at the end of the hollow bushing 203 maintains continuous elastic pressure on the positioning plate 101 while allowing for a smooth transition during circumferential adjustment. Compared to the prior art where the spring pin is directly fixed to the handle body 2, this structure significantly reduces the radial sway amplitude of the assembly during frequent operation. Simultaneously, the precise guidance of the steel ball's movement trajectory by the hollow bushing 203 ensures uniform pressure distribution on the positioning contact surface, effectively avoiding wear problems caused by localized stress concentration.

[0051] like Figure 2-5As shown, the clutch control disc 4 is positioned between the mounting disc 202 and the positioning disc 101. An arc-shaped through-hole 401 is constructed on the clutch control disc 4. The hollow bushing 203 on the mounting disc 202 passes through the arc-shaped through-hole 401, causing the steel ball of the spring pin assembly 201 to elastically press against the positioning disc 101. Specifically, the clutch control disc 4 is located in the axial clearance between the mounting disc 202 and the positioning disc 101. The size of the axial clearance is configured to allow the clutch control disc 4 to maintain a stable axial position without affecting the relative movement of the mounting disc 202 and the positioning disc 101. The curvature range of the arc-shaped through-hole 401 is determined according to the movement trajectory of the hollow bushing 203, and the width of the through-hole is slightly larger than the outer diameter of the hollow bushing 203 to provide rotational clearance. As a preferred embodiment, the arc-shaped through-hole 401 can be configured as a concentric arc, with its center coaxial with the central pivot 3, thereby ensuring smooth movement of the hollow bushing 203 within the through-hole. Furthermore, the steel balls of the spring pin assembly 201 maintain continuous pressure on the positioning disc 101 through the preload of the spring inside the hollow bushing 203. This pressure is configured to maintain circumferential positioning stability while allowing the handle body 2 to drive the clutch control disc 4 to overcome friction and achieve synchronous rotation during adjustment. Thus, this technical solution achieves spatial optimization through axial layered arrangement, and the stacked structure of the clutch control disc 4, mounting disc 202, and positioning disc 101 avoids radial interference between components. The arc-shaped through-hole 401 provides a directional movement channel for the hollow bushing 203, ensuring the relative rotational freedom of the mounting disc 202 and the clutch control disc 4. The elastic pressure mechanism of the steel balls maintains positioning accuracy while allowing for moderate flexible deformation during operation. Compared with existing technologies, this solution, through integrated structural design, simultaneously achieves the coordinated operation of clutch control and circumferential positioning functions within a limited space, solving the technical challenges of multi-component spatial layout and linkage coordination. It 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 both sides of the positioning disc 101. The central pivot 3 passes through the central hole of the positioning disc 101 and the central hole of the clutch control disc 4, and its two ends are respectively fixedly connected to the handle body 2 and the resistance control disc 5. Specifically, the clutch control disc 4 and the resistance control disc 5 are respectively disposed on both sides of the positioning disc 101, wherein the central hole of the positioning disc 101 is used to accommodate the central pivot 3. The central pivot 3 passes through the central hole of the positioning disc 101 and the central hole of the clutch control disc 4, and its two ends are respectively fixedly connected to the handle body 2 and the resistance control disc 5. As a preferred embodiment, the central pivot 3 can be fixedly connected to the handle body 2 and the resistance control disc 5 by means of threaded connection, welding or keyway fit. The central hole of the clutch control disc 4 can be configured to have a clearance fit or 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 be further fixed to the central pivot 3 by means of pin fixation or flange connection to ensure that the two rotate synchronously. Therefore, this technical solution achieves axial separation of the clutch control disc 4 and the resistance control disc 5 by arranging them on opposite sides of the positioning disc 101, thus avoiding mutual interference. The central pivot 3 passes through the positioning disc 101 and the clutch control disc 4, and is fixedly connected to the handle body 2 and the resistance control disc 5, ensuring that the handle body 2, clutch control disc 4, and resistance control disc 5 can rotate around the same axis. This arrangement and connection method solves the technical problems of axial arrangement of the two discs and connection of the central pivot, achieving a compact structure and functional integration. Compared with existing technologies, this solution achieves the linkage and positioning of multiple functional components through a single central pivot 3, simplifying the structure and improving 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 for driving the radial movement of the control block 601, and a return spring 603. A slot 402 is provided on the clutch control disc 4. When the control block 601 is inserted into the slot 402, the handle body 2 and the clutch control disc 4 are circumferentially linked; when the control block 601 is removed from the slot 402, the handle body 2 and the clutch control disc 4 are disengaged. The control block 601 can have a cylindrical or rectangular cross-section structure or an irregular shape, and its radial movement is precisely positioned via a guide groove or slide rail. The drive assembly can be a button type, lever type, or electromagnetic drive type. The button type drive converts axial pressing into radial displacement through a inclined plane mechanism, as detailed below. The return spring 603 is preferably a cylindrical helical spring, but a disc spring or elastic sheet structure can also be used. The slot 402 is designed as a groove matching the shape of the control block 601, and its depth must ensure that it can withstand circumferential torque after insertion. A wear-resistant coating can be added to the groove wall. This solution achieves reliable switching between linked states through a mechanical interlock structure. The drive component applies radial force to cause the control block 601 to engage with the slot 402, forming a rigid connection to transmit torque. The return spring 603 provides a counterforce to ensure rapid disengagement. The radially movable design reduces axial space occupation, making the overall structure compact. Compared to a separate handle, the integrated design simplifies the operation process, allowing for clutch switching with one hand and avoiding coordination issues associated with multi-handle operation. The slot 402 and control block 601 have high precision, with no relative slippage in the linked state, ensuring adjustment stability. The preload of the return spring 603 is adjustable to adapt to different operating force requirements, improving the user experience.

[0054] In a specific implementation, the clutch control mechanism further 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, with its upper end cooperating with the drive assembly and its lower end fixed to the control block 601. The return 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 injection molding of engineering plastic, and its thickness is clearance-fitted with the movable groove 605 to ensure smooth sliding. The cross-sectional shape of the spring groove 606 matches the outer diameter of the return spring 603, and can be circular or rectangular. A limiting boss can be provided at the bottom of the groove to prevent the spring from falling off. The width of the slot 608 in the cover plate 607 is 0.5-1mm larger than the output end of the control block 601, with a 2-3mm allowance for movement in the length direction. This technical solution, through the precise fit between the movable slot 605 and the movable plate 604, strictly restricts the movement of the control block 601 to the radial direction, avoiding jamming caused by deflection. The return spring 603 provides a stable return force, ensuring that the control block 601 accurately returns to its initial position after the external force is removed. The design of the fit between the cover plate 607 and the slot 608 not only limits the travel of the control block 601 but also ensures precise alignment of its output end with the slot 402 of the clutch control disc 4. The synergistic effect of the mechanical limiting structure and the elastic return mechanism achieves highly reliable operation of the clutch control mechanism, solving the problems of unstable motion trajectory and insufficient return accuracy in existing technologies.

[0055] like Figure 3 and 5As shown, a grip bar 209 is provided on the top of the handle body 2. The drive assembly includes a button 609 movably disposed inside the grip bar 209. The end of the button 609 extends out of the end of the grip bar 209 as the force-applying end, and the button 609 engages 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 press radially inward; when the external force is removed, the return spring 603 drives the movable plate 604 to move radially outward and pushes the button 609 out. The grip bar 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 engagement structure preferably adopts a 45° tilt angle to achieve a proportional conversion between axial pressing force and radial movement force. This technical solution integrates the drive component inside the grip lever 209, enabling direct linkage between the natural thumb pressing action and clutch control during single-handed operation. When button 609 is pressed, the inclined structure converts the axial force into radial displacement of the movable plate 604, pushing the control block 601 into the slot 402 of the clutch control disc 4. After button 609 is released, the return spring 603 simultaneously resets the movable plate 604 and rebounds the button 609, forming a self-locking operating cycle. Compared to the split operating mechanism in the prior art, this design reduces operating steps, avoids the need for eye shift, and ensures synchronous action through mechanical linkage. The inclined transmission structure reduces component wear while ensuring operating force, and the bidirectional action of the return spring 603 simplifies the complexity of the reset mechanism.

[0056] like Figure 6 As shown, the positioning base 1 also includes a surrounding plate 103 disposed on at least one axial end face edge of the positioning disk 101, forming a chamber between the surrounding plate 103 and the positioning disk 101 for mounting the clutch control disk 4 and / or the resistance control disk 5. The surrounding plate 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. In the unadjusted state, the protrusion 611 of the control block 601 is engaged in the lock hole 104, and the handle body 2 and the control block 601 are circumferentially locked. When adjusting the clutch, the control block 601 is embedded in the slot 402 and the protrusion 611 is disengaged from the lock hole 104, and the handle body 2 is circumferentially linked with the clutch control disc 4. When adjusting the resistance, the control block 601 is disengaged from the slot 402 and the protrusion 611 enters the resistance adjustment sliding hole 105, the handle body 2 is disengaged from the clutch control disc 4, and the handle body 2 drives the resistance control disc 5 to rotate and achieves circumferential positioning relative to the positioning disc 101 based on the circumferential positioning mechanism.

[0057] In this design, the enclosure 103 can adopt a ring-shaped or partially arc-shaped structure, and its height is determined according to the thickness of the clutch control disc 4 and the resistance control disc 5. The locking hole 104 and the resistance adjustment sliding hole 105 are located on the same circumferential surface of the enclosure 103. The locking hole 104 is a circular or rectangular through hole, with a diameter 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, its curvature matching the rotation trajectory of the handle body 2, and its length meeting the resistance adjustment stroke requirements. The protrusion 611 can be a cylindrical pin, a hemispherical structure, or a rectangular protrusion, and is integrally, welded, or threadedly fixed to the radially outer surface of the control block 601. This technical solution achieves integrated installation of the clutch control disc 4 and the resistance control disc 5 through the cavity formed by the enclosure 103. The cooperation between the locking hole 104 and the protrusion 611 ensures mechanical locking stability in the unadjusted state, while the resistance adjustment sliding hole 105 provides motion guidance and limiting functions for the resistance adjustment mode. The control block 601's three position state switching logic enables single-handed operation to switch between clutch adjustment, resistance adjustment, and locking states, significantly simplifying the operation process. Compared to existing split handles, this integrated design reduces the number of parts and lowers structural complexity, while a mechanical interlocking structure ensures the reliability of switching between various functional modes. The synergistic effect of the circumferential positioning mechanism and the resistance adjustment sliding hole 105 further improves the 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, this application also proposes an auxiliary locking component 7, including a base 701 fixed on the positioning seat 1, and a positioning block 702 and a positioning spring 703 disposed within the positioning seat 1. A positioning through hole 403 is provided on the clutch control disc 4, and a slider 404 is disposed within the positioning through hole 403. The positioning block 702 is pressed against the clutch control disc 4 under the action of the positioning spring 703. Only when the clutch control disc 4 is adjusted to the engaged state, the positioning through hole 403 moves to align with the positioning block 702, the positioning block 702 engages in the positioning through hole 403, and pushes the slider 404. When it is necessary to disengage, the operating control block 601 is pressed into the slot 402, the handle body 2 and the clutch control disc 4 are circumferentially linked, and simultaneously 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. Its installation position must ensure that the movement trajectory of the positioning block 702 intersects perpendicularly with the rotation plane of the clutch control disc 4. The positioning block 702 is preferably a cylindrical structure, with a tapered guide surface at its end to reduce frictional resistance when inserted into the positioning through hole 403. The positioning spring 703 can be a helical compression spring, and its preload must meet the mechanical requirements of reliably pressing the clutch control disc 4 while also being smoothly ejected by the slider 404. The slider 404 can be designed as a T-shaped structure, with a matching inclined surface on its head contacting the control block 601. This technical solution, by adding a mechanical interlocking structure, ensures that when the clutch control disc 4 rotates to the engaged position, the positioning block 702 automatically engages with the positioning through hole 403 to form a rigid limit, effectively preventing accidental disengagement due to vibration or misoperation. In this design, the elastic compressive force of the positioning spring 703 ensures that the positioning block 702 remains in contact with the clutch control disc 4, while the linkage design of the slider 404 ensures that the unlocking operation is completed synchronously with the action of the control block 601. Compared with existing technologies, this solution maintains the convenience of single-handed operation while significantly improving the stability of the engaged state through a two-stage positioning mechanism, thus solving the problem of unstable positioning caused by uneven tension of the clutch pull rope in integrated handles.

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

[0060] 1. Initial state (unadjusted state)

[0061] -Status Description:

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

[0063] - The resistance is in an unconnected state (the resistance control cable is in a slack position, and the magnetic reluctance device 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 plate, and the handle body is circumferentially locked to the positioning seat, making it impossible to rotate.

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

[0067] -Press the button:

[0068] Press the button at the top of the grip with your thumb. The button drives the movable plate to move radially inward through the inclined plane transmission, causing the control block to retract and exit the lock hole.

[0069] -Linked confirmation:

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

[0071] 3. Adjust to the clutch position;

[0072] - Press and hold the button, rotate the handle body until the clutch control disc rotates to the engagement position, at which point the clutch is just adjusted to the engaged state.

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

[0074] -Release the button:

[0075] After releasing the thumb, the reset spring pushes the movable plate to reset, the control block exits the slot of the clutch control disc, and the handle body disengages from the clutch control disc.

[0076] -State transition:

[0077] - Clutch state 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: This is the lowest resistance level.

[0080] 5. Adjust the resistance level

[0081] - Rotate to select gear:

[0082] - Rotate 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 (reduce resistance): loosen the resistance control cable and reset the magnetic reluctance device.

[0084] - Gear lock:

[0085] The spring pin assembly is sequentially inserted into the positioning holes of the positioning plate, with each setting corresponding to a resistance level (a "click" sound and a pause in the handle can be felt).

[0086] 6. Switch back to clutch adjustment mode

[0087] -Prerequisites for operation:

[0088] Rotate the handle to the lowest resistance setting (i.e., the clutch engaged position). At this point, the protrusion of the control block moves to the end of the resistance adjustment sliding hole.

[0089] -Press the button:

[0090] Pressing the button at the top of the grip lever causes the control block to re-engage with the clutch control disc, and the handle body and the clutch control disc move in circumferentially together.

[0091] -Remove assist lock:

[0092] The control block pushes the slider on the clutch control disc, pushing the positioning block out of the positioning through hole and releasing the mechanical lock of the clutch state.

[0093] 7. Return to the initial locked state

[0094] -After adjustment:

[0095] Rotate the handle to the initial position, and the control block protrusion will automatically engage with the locking hole in the panel, returning the handle to its unadjusted state.

[0096] -Reset check:

[0097] If the handle cannot be rotated and the buttons are fully ejected, it indicates that the clutch is disengaged, the resistance is not engaged, and all functions have been reset.
