Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a locking structure for a treadmill and its clutch handle. Background Technology

[0002] As people's demands for the quality and user experience of fitness equipment increase, resistance devices are being installed on fitness equipment (such as treadmills, elliptical trainers, and exercise bikes) to increase exercise intensity and achieve better fitness results. These resistance devices can be traditional friction-based resistance adjustment methods, magnetic resistance devices, water resistance devices, and air resistance devices, among others. Currently, some fitness equipment on the market allows the resistance devices to be engaged or disengaged via a clutch control.

[0003] When applied to exercise equipment, magnetic resistance structures allow users to easily adjust the resistance encountered during exercise via knobs, buttons, and other methods. Unlike traditional friction resistance adjustments, which require manual adjustment of the tightness of mechanical parts, this method is simpler and faster, allowing users to change the resistance according to their exercise intensity and physical condition. However, traditional clutch operation methods have some problems. Mechanical clutches often require foot pedal operation or manual pulling, which is relatively complex and inconvenient. Although clutch button structures allow for engagement or disengagement with a simple press of a button, greatly simplifying operation and reducing physical exertion, existing clutch button structures still have some shortcomings.

[0004] For example, existing clutch button structures may have the following problems: complex structure, many parts, increasing manufacturing costs and failure rate; insufficient button operation, requiring greater pressing force to achieve clutch operation; lack of a reliable locking mechanism, which may lead to unexpected changes in clutch state; and low integration between the button structure and the handle, affecting overall aesthetics and operating comfort.

[0005] Furthermore, existing clutch lever structures often lack effective anti-misoperation designs, and accidental contact during use may alter the clutch engagement state, affecting the smoothness and safety of movement. Additionally, some clutch lever structures lack durability and may loosen or fail after prolonged use.

[0006] To address the aforementioned issues, existing technologies urgently need improvement. Summary of the Invention

The actuating rod and the locking pin are axially movable within the rocker handle, and the end of the actuating rod and the beginning of the locking pin are connected by the connecting rod. The first elastic reset component acts on the actuating rod or the locking pin, and the elastic force of the first elastic reset component is used to drive the locking pin to maintain a locked state. The input component can act on the actuating rod and can drive the actuating rod and its connected locking pin to move axially to release the above-mentioned locking state.

[0013] Furthermore, this application also proposes that the keying component includes a key and a second elastic reset component that elastically supports the key, the starting end of the actuation rod supports the side wall of the key and engages with it in a wedge shape, and the actuation rod can be driven to move axially when the key is pressed or ejected.

[0014] Furthermore, this application also proposes that an annular groove is formed on the side wall of the button, the bottom of the annular groove has a variable diameter section, and a ball is embedded in the annular groove, with the starting end of the actuating rod supported on the ball.

[0015] Furthermore, this application also proposes that the rocker handle includes a left housing, a right housing, and a positioning cover plate; the lower ends of the left housing and the right housing are respectively rotatably disposed on both sides of the upper end of the column, the positioning cover plate includes a cover part and a cylindrical part, the cover part covers the inner wall of the left housing or the right housing, the locking component is positioned in the left housing or the right housing connected to the cover part, and the cylindrical part is located between the upper end of the left housing and the upper end of the right housing as a gripping part.

[0017] Furthermore, this application also proposes that a positioning block is fixedly connected to the left or right housing, and the positioning block rotates synchronously with the rocker arm handle; the positioning block is provided with several sets of elastic pin assemblies, and the output end of the elastic pin assembly is used to support the positioning groove in the upper side wall of the column, thereby positioning the rocker arm handle relative to the column.

[0018] Furthermore, this application also proposes that an anti-slip sleeve is fitted on the outer side of the cylindrical part of the positioning cover plate, and the two ends of the anti-slip sleeve are respectively supported on the upper end of the left shell or the right shell.

[0019] Furthermore, this application also proposes a treadmill including the aforementioned locking structure for the clutch handle.

[0033] Example 1:

[0034] like Figures 1-5 As shown, this embodiment relates to a locking structure for a clutch handle, comprising a rocker handle 1 rotatably mounted on the upper end of a column 4. The rocker handle 1 is connected to a clutch drive assembly 5 for driving the clutch mechanism. A locking assembly 2 and a keying assembly 3 for driving the locking assembly 2 are provided on the rocker handle 1 or the column 4. The locking assembly 2 locks the rocker handle 1 to the column 4, and the keying assembly 3, acting on the locking assembly 2, releases the locking relationship, allowing the rocker handle 1 to rotate relative to the column 4, thereby driving the clutch drive assembly 5. This technical solution achieves the locking and unlocking functions of the clutch handle on the column 4 by setting the locking assembly 2 and the keying assembly 3. The locking assembly 2 fixes the rocker handle 1 to the column 4, preventing it from rotating freely, while the keying assembly 3, acting on the locking assembly 2, releases the locking state, allowing the rocker handle 1 to rotate freely, thereby driving the clutch drive assembly 5. The clutch drive assembly 5 can be a shift fork clutch device or a traction clutch device connected to the clutch wheel. This design solves the problems of complex operation and unstable locking of traditional clutch levers, improves the ease of operation, accurately controls power transmission, and allows for quick and flexible button operation. It can adapt to a variety of complex working conditions and improve equipment safety.

[0035] Furthermore, this application proposes that the locking component 2 is disposed on the rocker handle 1, and the keying component 3 is disposed on the grip end of the rocker handle 1. When the end of the locking component 2 can be locked onto the column 4, the rocker handle 1 is locked onto the column 4. Thus, the placement of the locking component 2 and the keying component 3 optimizes operational convenience. With the locking component 2 located on the rocker handle 1 and the keying component 3 located on the grip end, this layout allows the user to directly operate the keying component 3 through the grip end to control the locking and unlocking of the locking component 2. This design simplifies the operation steps and improves ease of use and efficiency. Compared with the prior art, the technical solution of this application, by placing the locking component 2 and the keying component 3 on the rocker handle 1 and the grip end respectively, allows the user to lock and unlock without additional manual adjustment, simply by using the keying component 3 on the grip end, greatly simplifying the operation process and improving the user experience.

[0036] like Figure 2As shown, the rocker handle 1 includes a left housing 11, a right housing 12, and a positioning cover plate 13. The lower ends of the left housing 11 and the right housing 12 are rotatably mounted on both sides of the upper end of the column 4. The positioning cover plate 13 includes a cover portion 131 and a cylindrical portion 132. The cover portion 131 covers the inner wall of the left housing 11 or the right housing 12. The locking assembly 2 is positioned inside the cover portion 131 and the left housing 11 or the right housing 12 to which it is connected. The cylindrical portion 132 is located between the upper end of the left housing 11 and the upper end of the right housing 12 as a gripping part. Specifically, the lower ends of the left housing 11 and the right housing 12 are rotatably mounted on both sides of the upper end of the column 4 via bearings or bushings, allowing the rocker handle 1 to rotate flexibly. The cover portion 131 of the positioning cover plate 13 is fixed to the inner wall of the left housing 11 or the right housing 12 by screws or clips. The locking assembly 2 is positioned within the left housing 11 or the right housing 12 connected to the cover portion 131 by positioning pins or bolts, ensuring the stability and accuracy of the locking assembly 2. The cylinder portion 132 is...

[0037] Manufactured using injection molding or die casting, the handle 1 is positioned between the upper ends of the left housing 11 and the right housing 12, serving as a grip and creating a convenient gripping area between them. Therefore, this application simplifies the assembly process by designing the rocker handle 1 as a combination of the left housing 11, right housing 12, and positioning cover 13. The lower ends of the left housing 11 and right housing 12 are rotatably mounted on both sides of the upper end of the column 4, allowing the rocker handle 1 to rotate flexibly. The cover portion 131 of the positioning cover 13 covers the inner wall of either the left housing 11 or the right housing 12, and the locking component 2 is positioned within the cover portion 131 and the connected left housing 11 or right housing 12, ensuring the stability and accuracy of the locking component 2. The cylindrical portion 132, positioned between the upper ends of the left housing 11 and the right housing 12, serves as a grip, creating a convenient gripping area between them. This design not only simplifies the assembly process but also improves operational convenience and stability. Compared with the prior art, the technical solution of this application significantly reduces the assembly complexity and inconvenience of operation of the clutch handle locking structure by optimizing the structural design, and has high practicality and innovation.

[0038] like Figure 2As shown, a positioning block 14 is fixedly connected to the left housing 11 or the right housing 12, and the positioning block 14 rotates synchronously with the rocker arm handle 1. The positioning block 14 is provided with several sets of elastic pin assemblies 15. The output end of the elastic pin assembly 15 is used to support itself in the positioning groove on the upper side wall of the column 4, thereby positioning the rocker arm handle 1 relative to the column 4. Specifically, the positioning block 14 is fixed to the left housing 11 or the right housing 12 by bolts or welding to ensure its synchronous rotation with the rocker arm handle 1. The positioning block 14 is provided with several sets of elastic pin assemblies 15, each elastic pin assembly including an elastic pin and a spring. The output end of the elastic pin is supported in the positioning groove on the upper side wall of the column 4 under the action of the spring. The number of elastic pin assemblies 15 can be adjusted according to actual needs, for example, two or four sets of elastic pin assemblies 15 can be provided to enhance the stability of positioning. The material of the elastic pin can be selected as alloy steel with good elasticity and wear resistance to ensure its long-term reliability. Therefore, this technical solution solves the problem of unstable positioning of the rocker arm handle 1 relative to the column 4 by setting the positioning block 14 and the elastic pin assembly 15. The positioning block 14 is fixed to the left housing 11 or the right housing 12 and rotates synchronously with the rocker arm handle 1, ensuring the consistency of movement between the positioning block 14 and the rocker arm handle 1. The output end of the elastic pin assembly 15 is supported in the positioning groove on the upper side wall of the column 4. Through the elastic force of the elastic pin, the rocker arm handle 1 can be initially positioned on the column 4 during rotation, avoiding shaking or displacement of the rocker arm handle 1 during use. Compared with the prior art, this solution has a simple structure, good positioning effect, and can effectively improve the stability and ease of operation of the rocker arm handle 1.

[0039] exist Figure 2-4 In the specific embodiment shown, the locking assembly 2 includes an actuating rod 21, a locking pin 22, a connecting rod 23, and a first elastic reset component 24. The actuating rod 21 and the locking pin 22 are axially movable within the rocker handle 1, and the end of the actuating rod 21 and the beginning of the locking pin 22 are connected via the connecting rod 23. The first elastic reset component 24 acts on the actuating rod 21 or the locking pin 22, and the elastic force of the first elastic reset component 24 drives the locking pin 22 to maintain it in a locked state. The locking assembly 3 can act on the actuating rod 21, driving the actuating rod 21 and its connected locking pin 22 to move axially, thereby releasing the above-mentioned locking state. Specifically, the axial movement of the actuating rod 21 and the locking pin 22 is arranged so that the locking state can be maintained stably by the elastic force of the first elastic reset component 24. The end of the actuating rod 21 and the beginning of the locking pin 22 are connected via the connecting rod 23.

[0040] This design ensures synchronous movement of the starting rod 21 and the locking pin 22. The first elastic reset component 24 can act on either the starting rod 21 or the locking pin 22. In the embodiment shown, the first elastic reset component 24 is sleeved on the starting rod 21, and its elastic force drives the locking pin 22 to remain in the locked state. The input component 3 can act on the starting rod 21, driving both the starting rod 21 and its connected locking pin 22 to move axially, thereby releasing the locked state. As a preferred embodiment, the axial movement of the starting rod 21 and the locking pin 22 can be achieved using sliding bearings or linear guides to ensure smooth and stable movement. The connecting rod 23 can be made of a rigid material to ensure a strong connection and accurate transmission. The first elastic reset component 24 can be a spring or elastic sheet, and its elastic force can be adjusted according to actual needs. The input component 3 can be a button or lever, and its operation method can be designed according to the actual application scenario.

[0041] Therefore, the technical solution of this application achieves the locking and unlocking functions of the rocker arm handle 1 through the cooperation of the starting rod 21, locking pin 22, connecting rod 23, and first elastic reset component 24. The axial movement of the starting rod 21 and locking pin 22 ensures that the locked state is maintained stably by the elastic force of the first elastic reset component 24, while the input component 3 drives the starting rod 21 and locking pin 22 to move, thereby releasing the locked state. This design not only ensures the stability of the locked state but also achieves a convenient unlocking function through the operation of the input component 3. Compared with the prior art, the technical solution of this application has a simple structure and is easy to operate, effectively improving the user experience of the rocker arm handle 1.

[0042] like Figure 2 As shown, the input component 3 includes a button 31 and a second elastic reset component 32 that elastically supports the button 31. The starting end of the actuating rod 21 supports the side wall of the button 31 and engages with it in a wedge shape. When the button 31 is pressed or released, it can drive the actuating rod 21 to move axially. This application simplifies the clutch operation structure by introducing the button 31 and the second elastic reset component 32. The wedge-shaped engagement between the button 31 and the actuating rod 21 allows the pressing or releasing of the button 31 to directly drive the actuating rod 21 to move axially, thereby releasing the locked state. This design allows the operator to engage or disengage the clutch simply by pressing the button 31, greatly facilitating operation and reducing operational difficulty and physical exertion. The function of the second elastic reset component 32 is to ensure that the button 31 can automatically reset after operation, maintaining the stability of the system and the continuity of operation. Compared with the prior art, the technical solution of this application can achieve quick clutch control through the simple operation of the button 31, avoiding the problem of complex mechanical operation required in traditional clutch operation, and significantly improving the convenience and efficiency of operation.

[0043] In a specific implementation, an annular groove 311 is formed on the side wall of the button 31. The bottom of the annular groove 311 has a variable diameter section 312, and a ball bearing 33 is embedded in the annular groove 311. The starting end of the actuating rod 21 rests on the ball bearing 33. Specifically, the design of the annular groove 311 allows the actuating rod 21 to move axially through the rolling of the ball bearing 33 when the button 31 is pressed or released, thereby releasing the locked state. The ball bearing 33 reduces the friction between the button 31 and the actuating rod 21, making the operation smoother. The design of the annular groove 311 ensures the stable movement of the ball bearing 33 within the annular groove 311, further improving the reliability and accuracy of the operation. The variable diameter section 312 achieves the aforementioned wedge fit, allowing the button 31 to move axially through the actuating rod 21 when pressed or released. As a preferred embodiment, the variable diameter section 312 of the annular groove 311 can be designed to gradually narrow or widen to accommodate different operating forces. In addition, the ball bearing 33 can be made of high-hardness steel balls or...

[0044] Other wear-resistant materials are used to enhance its service life and stability. Therefore, this technical solution designs an annular groove 311 and its variable diameter section 312 on the side wall of the button 31, and embeds a ball bearing 33 within the annular groove 311, allowing the starting end of the actuating rod 21 to rest on the ball bearing 33. This design not only solves the fit problem between the button 31 and the actuating rod 21, but also improves the smoothness and reliability of operation by reducing friction and ensuring the stable movement of the ball bearing 33. Compared with existing technologies, this solution has significant advantages in terms of ease of operation and accuracy, effectively improving the user experience.

[0045] Furthermore, the button 31 of the input component 3 is movably embedded in the upper end of the left housing 11 or the right housing 12. The second elastic reset component 32 is constructed as a spring located inside the cylindrical portion 132 of the positioning cover plate 13, with its outer end supporting the button 31. Specifically, the button 31 is movably embedded in the upper end of the left housing 11 or the right housing 12, allowing the button 31 to move within a certain range within the housing, thereby realizing the input operation. The second elastic reset component 32 is in the form of a spring, located inside the cylindrical portion 132 of the positioning cover plate 13, with its outer end supporting the button 31, allowing the button 31 to automatically reset after operation. This design not only improves the installation stability of the button 31 but also enhances the convenience and comfort of operation. Thus, by movably embedding the button 31 in the upper end of the housing and using a spring as the second elastic reset component 32, this application effectively solves the technical problem of unstable installation and inconvenient operation of the button 31 of the input component 3 in the clutch handle locking structure. The secure installation of button 31 prevents it from loosening or falling off during use, while the elastic feedback of the spring improves the convenience and comfort of operation. Compared with the prior art, the structural design of this application is simpler, the operation is smoother, and the user experience of the clutch handle locking structure is significantly improved.

[0046] Furthermore, an anti-slip sleeve 16 is fitted onto the outer side of the cylindrical portion 132 of the positioning cover plate 13. The two ends of the anti-slip sleeve 16 are respectively supported on the upper ends of the left housing 11 or the right housing 12. The anti-slip sleeve 16 can be made of various materials, such as rubber, silicone, or other materials with a high coefficient of friction. The surface of the anti-slip sleeve 16 can be designed with an uneven texture to further increase friction. The two ends of the anti-slip sleeve 16 can be firmly fixed to the upper ends of the left housing 11 or the right housing 12 by snaps, adhesives, or other fixing methods, ensuring that it will not fall off or shift during use. Specifically, the anti-slip sleeve 16 increases the friction of the grip, preventing the user's hand from slipping during operation and improving operational stability and safety. Through the supporting action of the anti-slip sleeve 16, it ensures that the anti-slip sleeve 16 is firmly fixed to the cylindrical portion 132, preventing it from falling off or shifting during use. This design not only solves the technical problem of easy slippage of the grip but also improves the overall user experience of the clutch handle. Therefore, the technical solution of this application effectively solves the problem of easy slippage of the grip by setting the anti-slip sleeve 16, thereby improving the stability and safety of operation. Compared with the prior art, the technical solution of this application has the advantages of simple structure, convenient installation, and significant effect.

[0047] Based on the aforementioned locking structure of the clutch handle, its execution process is as follows:

[0048] 1. Unlocking Process: When the button is pressed, it is pushed in. The variable diameter section 312 of the button drives the actuating rod 21 to move axially based on the ball bearing 33. A linkage structure is designed here. The actuating rod 21 and the locking pin 22 are connected end to end to the connecting rod 23 by a positioning pin. The moving areas of the actuating rod 21, the locking pin 22, and the connecting rod 23 are restricted by the positioning cover plate 13 structure.

[0049] The lower end of the pin 22 is fixed inside the right housing 12 by the fixing attachment 17, and the movement direction of the locking pin 22 is fixed. Therefore, under the above-mentioned movement action, the connecting rod 23 will give the locking pin 22 an upward pulling force, causing the locking pin 22 to exit the slot. At this time, the rocker arm handle 1 can rotate back and forth, so that the clutch can be controlled by the clutch drive assembly 5.

[0050] Second, the locking process: After adjustment, release the button, the second elastic reset component 32 will pop out the drive button, and at the same time the first...

[0051] An elastic reset component 24 provides an upward elastic force to the starter lever 21, and through the connecting rod 23, it provides a downward thrust to the locking pin 22, causing the locking pin 22 to move downward and insert into the slot for positioning. At this time, the rocker arm handle 1 cannot be moved.

[0052] Example 2:

[0053] This embodiment proposes a treadmill including a locking structure for a clutch handle, which adopts the structure described in Embodiment 1. Therefore, the technical solution of this application solves the problems of complex and inconvenient operation of clutch handle locking structures on treadmills by simplifying the clutch handle locking structure. Specifically, this locking structure, through the cooperation of the rocker handle 1, the locking component 2, and the keying component 3, achieves quick locking and unlocking of the clutch handle, improving ease of use. Compared with the prior art, this solution has a simpler structure, is more convenient to operate, and reduces operational difficulty and physical exertion.
