Description

Technical Field

[0001] This utility model relates to the field of adjustable unlocking structure technology, and in particular to a double-ended unlocking structure, a double lever arm assembly with a double-ended unlocking structure, and fitness equipment with a double-ended unlocking structure. Background Technology

[0002] With increasing health awareness and higher demands for physical fitness, fitness equipment is being used more and more widely in daily life. Resistance band machines, as an important type of strength training equipment, are favored by many fitness enthusiasts because they effectively target the upper limbs, back, and core muscles. These machines are typically equipped with adjustable lever arms, allowing users to adjust the position or angle of the lever arm according to their individual physical condition and training needs to achieve the best training results.

[0003] However, in existing resistance training machine designs, when the lever arm needs to be adjusted, a knob locking mechanism or other small manual locking device is commonly used. This traditional locking method has certain limitations:

[0004] 1. Inconvenient to operate: Due to the small size of the knob, users often need to use their fingers to tighten or loosen it, which may be a challenge for people with weak hand strength or poor joint flexibility.

[0005] 2. Low adjustment efficiency: Each adjustment requires unlocking, adjusting and relocking each lever arm separately, which is cumbersome, especially when training postures need to be changed frequently.

[0006] 3. Potential safety hazards: If the knob is not tightened sufficiently, the lever arm may move unexpectedly during use, which may affect the exercise effect or even cause injury.

[0007] In addition, while some improved designs attempt to simplify the adjustment process by introducing automation such as electric controls, these solutions often come with increased costs and technical complexity, and are not always suitable for all types of fitness environments and individual preferences.

[0008] Therefore, developing a new lever arm locking and unlocking system that can maintain a simple and reliable structure while being easy for users to operate has become one of the urgent technical problems to be solved in the current fitness equipment field. Utility Model Content

[0009] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a double-end unlocking structure, which achieves double-end unlocking through a transmission mechanism that drives the connecting rope via a control handle. This allows users to easily operate the device using their entire palm, improving ease of operation and comfort. Furthermore, the simplified one-to-two control structure not only reduces component complexity but also enhances the safety and reliability of the equipment. It is applicable to various fitness equipment, broadly improving the user experience and ease of use of the equipment.

[0014] A control assembly, connected to the frame and located between the two adjustment assemblies, includes a control handle and a connecting rope. The two ends of the connecting rope are respectively connected to the two vertical locking components. The control handle is connected to the connecting rope and can drive one end of the connecting rope to move along the side facing the control handle to unlock the horizontal adjustment component locked corresponding to the vertical locking component.

[0015] The dual-end unlocking structure described in this utility model has at least the following beneficial effects: By using a connecting rope transmission mechanism, the control handle is connected to the upper and lower vertical locking components, thereby enabling a single component to control two horizontal adjustment components. This eliminates the need for users to adjust each adjustment component separately at different positions; instead, they can control one or both adjustment components simultaneously by pulling or pushing a single control handle, greatly simplifying the operation and improving adjustment efficiency. Furthermore, since the control handle can be operated using the entire palm, rather than just the fingertips, this not only increases the contact area during operation but also reduces finger pressure, making it particularly user-friendly for users with limited hand strength or dexterity. Overall, this simple and efficient unlocking mechanism not only enhances user convenience and comfort but also reduces the complexity of equipment maintenance, providing users with a safer, more reliable, and easier-to-operate solution.

[0023] The double lever assembly according to this utility model includes the double-end unlocking structure described in this utility model.

[0024] The dual-arm assembly described in this utility model has at least the following beneficial effects: By employing the aforementioned dual-end unlocking structure and connecting the control handle to the two vertical locking components via a connecting rope transmission mechanism, simultaneous control of two horizontal adjustment components by a single control handle is achieved. This design greatly simplifies the user's operation steps when adjusting the arm position or angle, improving adjustment efficiency. During use, the user only needs to pull or push a single control handle to easily unlock and relock the arm, avoiding the inconvenience and cumbersome process of traditional knob locking methods. Furthermore, since the control handle can be operated using the entire palm, rather than just the fingertips, this not only increases the contact area during operation but also reduces finger pressure, making it particularly user-friendly for users with less hand strength or limited dexterity. Overall, this simple and efficient unlocking mechanism not only improves user convenience and comfort but also reduces the complexity of equipment maintenance, providing users with a safer, more reliable, and easier-to-operate solution.

[0026] The fitness equipment according to this utility model has at least the following beneficial effects: Integrating the aforementioned dual-end unlocking structure significantly improves the user's operating experience and safety. By introducing a connecting rope transmission mechanism, the equipment connects the control handle to two vertical locking components, enabling simultaneous control of two horizontal adjustment components by a single control handle. This design not only simplifies the user's operation steps when adjusting the lever arm position or angle but also improves adjustment efficiency. During use, the user can pull or push a single control handle to operate one or both adjustment components simultaneously, thereby quickly and accurately adjusting the lever arm position. Furthermore, since the control handle can be operated using the entire palm, rather than just the fingertips, this not only increases the contact area during operation but also reduces finger pressure, making it particularly user-friendly for users with less hand strength or limited dexterity.

[0041] With increasing health awareness and higher demands for physical fitness, fitness equipment is being used more and more widely in daily life. Resistance band machines, as an important type of strength training equipment, are favored by many fitness enthusiasts because they effectively target the upper limbs, back, and core muscles. These machines are typically equipped with adjustable lever arms, allowing users to adjust the position or angle of the lever arm according to their individual physical condition and training needs to achieve the best training results.

[0042] However, in existing resistance training machine designs, when the lever arm needs to be adjusted, a knob locking mechanism or other small manual locking device is commonly used. This traditional locking method has certain limitations:

[0043] 1. Inconvenient to operate: Due to the small size of the knob, users often need to use their fingers to tighten or loosen it, which may be a challenge for people with weak hand strength or poor joint flexibility.

[0044] 2. Low adjustment efficiency: Each adjustment requires unlocking, adjusting and relocking each lever arm separately, which is cumbersome, especially when training postures need to be changed frequently.

[0045] 3. Potential safety hazards: If the knob is not tightened sufficiently, the lever arm may move unexpectedly during use, which may affect the exercise effect or even cause injury.

[0046] In addition, while some improved designs attempt to simplify the adjustment process by introducing automation such as electric controls, these solutions often come with increased costs and technical complexity, and are not always suitable for all types of fitness environments and individual preferences.

[0047] Therefore, developing a new lever arm locking and unlocking system that can maintain a simple and reliable structure while being easy for users to operate has become one of the urgent technical problems to be solved in the current fitness equipment field.

[0048] Therefore, such as Figures 1 to 3 As shown, the dual-end unlocking structure proposed in this utility model includes a frame 100, two adjustment components 200 respectively connected to the upper and lower sides of the frame 100, and a control component 300 connected to the frame 100 and located between the two adjustment components 200. Each adjustment component 200 includes a horizontal adjustment member 210 and a vertical locking member 220. The horizontal adjustment member 210 is movably disposed on the frame 100 in a horizontal direction, and the vertical locking member 220 is movably disposed on the frame 100 in a vertical direction and is used to lock the horizontal adjustment member 210. For example, the horizontal adjustment member 210 can rotate or slide horizontally relative to the frame 100. Then, the vertical locking member 220 moves vertically and contacts the horizontal adjustment member 210 to lock the horizontal adjustment member 210 and prevent further movement of the horizontal adjustment member 210. Specifically, the control component 300 includes a control handle 310 and a connecting rope 330. Both ends of the connecting rope 330 are connected to two vertical locking components 220. The control handle 310 is connected to the connecting rope 330 and can drive one end of the connecting rope 330 to move towards the side facing the control handle 310, thereby unlocking the horizontal adjustment component 210 locked to the vertical locking component 220. It should be noted that by using the transmission mechanism of the connecting rope 330 to connect the control handle 310 to the two vertical locking components 220, the function of controlling two horizontal adjustment components 210 with a single component is realized. This eliminates the need for users to adjust each adjustment component 200 separately in different positions. Instead, users can control one or both adjustment components 200 simultaneously by pulling or pushing a single control handle 310, greatly simplifying the operation and improving adjustment efficiency. Furthermore, since the control handle 310 can be operated using the entire palm, rather than just the fingertips, this not only increases the contact area during operation but also reduces finger pressure, making it particularly user-friendly for users with limited hand strength or dexterity. Overall, this simple and efficient unlocking mechanism not only improves user convenience and comfort but also reduces the complexity of device maintenance, providing users with a safer, more reliable, and easier-to-operate solution.

[0049] In some embodiments, the control handle is directly fixed to the connecting rope, and the control handle moves vertically to directly pull up or down the connecting rope (not shown in the figure). See also... Figure 2In some embodiments of this utility model, the control handle 310 is rotatably connected to the frame 100, and a rotating block 320 is fixedly connected to the control handle 310. One end of the connecting rope 330, away from the vertical locking component 220, is connected to the rotating block 320. Firstly, by setting the control handle 310 to a rotatable connection, the user can perform push-pull actions more naturally during operation, reducing the inconvenience and discomfort that might result from directly pulling the connecting rope 330. Furthermore, the rotatable connection design allows the control handle 310 to rotate smoothly, thus conforming more to ergonomic principles and improving the user's operating experience. Secondly, the fixed connection between the control handle 310 and the rotating block 320 ensures that force can be effectively transmitted to the connecting rope 330 during operation, thereby driving the vertical locking component 220 to unlock the horizontal adjustment component 210. This mechanical linkage design not only improves the efficiency of force transmission but also enhances the reliability and stability of the entire unlocking system.

[0050] Refer to Figure 1 In some embodiments of this invention, when the control handle 310 is horizontally positioned, the connecting rope 330 is taut, driving both horizontal adjustment components 210 into a locked state. This means that in a natural state, the locking force of the two vertical locking components 220 is greater than the tension of the connecting rope 330, thus ensuring that the two horizontal adjustment components 210 are securely locked in their current positions. This ensures the fitness equipment remains stable and safe when not in use, avoiding safety hazards caused by accidental movement of the lever arm. This is particularly important for users, especially during high-intensity training, as a stable device provides more reliable support and prevents any potential injury. Furthermore, by setting the control handle 310 horizontally, users can visually see and feel that the equipment is locked when not in use, which not only enhances user confidence but also reduces the possibility of misoperation. Users can easily visually check whether the equipment is fully locked, thereby improving safety. In addition, this design simplifies the user's operating process. When the lever arm position needs to be adjusted, the user only needs to pull or push the control handle 310 to deviate from the horizontal position to easily unlock the horizontal adjustment components 210. Once the adjustment is complete and the control handle 310 is released, it will automatically return to the horizontal position, the connecting rope 330 will straighten again, and the leveling adjustment component 210 will lock again. This self-locking mechanism is not only convenient and quick, but also ensures that the device can quickly return to the safe locked state after each adjustment.

[0051] Furthermore, refer to Figure 1The rotating block 320 is provided with a through hole 3201 for the connecting rope 330 to pass through. The center line of the through hole 3201 is offset from the rotation axis of the rotating block 320. Therefore, when the user rotates the operating handle 310, it will unlock the upper or lower leveling component 210. For example, rotating the handle 310 upwards unlocks the lower leveling component 210; rotating the handle 310 downwards unlocks the upper leveling component 210. Similarly, rotating the handle 310 upwards unlocks the upper leveling component 210; rotating the handle 310 downwards unlocks the lower leveling component 210. It is easy to understand that by providing the through hole 3201 on the rotating block 320, the connecting rope 330 can smoothly pass through and twist and contract under the rotation of the rotating block 320, thus ensuring effective force transmission. This design not only simplifies the installation and maintenance of the connecting rope 330 but also improves the stability and reliability of the entire unlocking system. The fixed position of the connecting rope 330 in the through hole 3201 effectively prevents it from slipping or loosening during operation, ensuring accurate operation every time. Secondly, by offsetting the center line of the through hole 3201 from the rotation axis of the rotating block 320, a lever effect is generated when the control handle 310 rotates, allowing the user to achieve a larger unlocking action with less force. This makes pulling or pushing the control handle 310 less strenuous, especially beneficial for users with limited hand strength or joint flexibility, improving overall ease of operation and comfort. Furthermore, this offset arrangement optimizes force distribution, ensuring the connecting rope 330 is more evenly stressed during movement, reducing localized stress concentration and extending its service life. It also reduces the risk of failure due to wear or breakage of the connecting rope 330, further enhancing the durability and safety of the device. In some embodiments, the center line of the through hole intersects perpendicularly with the rotation axis of the rotating block (not shown in the figure). In this case, when the user operates the control handle, both the upper and lower horizontal adjustment components will be unlocked simultaneously.

[0052] Optionally, the connecting rope is a single piece (not shown in the figure), with its middle portion passing through the through hole. The upper and lower ends of the connecting rope are respectively fixedly connected to the upper and lower vertical locking components. In some embodiments of this utility model, there are two connecting ropes 330, and the two connecting ropes 330 are respectively fixedly connected to the upper and lower vertical locking components 220. Specifically, as shown... Figure 1As shown, the connecting rope 330 includes a first segment 331 and a second segment 332. The opposite ends of the first segment 331 and the second segment 332 are fixed to the rotating block 320, and the opposite ends of the first segment 331 and the second segment 332 are fixed to two vertical locking components 220. It is easy to understand that the segmented design of the connecting rope 330 enhances the stability and reliability of the system. Each segment of the connecting rope 330 acts independently on a vertical locking component 220, ensuring balanced force transmission during operation. Even if one segment of the connecting rope 330 fails or wears out, the other segment can continue to work, reducing the risk of overall system failure. Furthermore, this design facilitates maintenance and replacement, because if a segment of the connecting rope 330 is damaged, only that segment needs to be replaced, rather than the entire connecting rope 330, reducing maintenance costs.

[0053] Reference Figures 1 to 3 In some embodiments of this utility model, the horizontal adjustment component 210 includes an adjustment seat 211 and an output rod 212. The output rod 212 is connected to the adjustment seat 211, which is rotatably connected to the frame 100 in the horizontal direction to adjust the swing angle of the output rod 212. This allows the user to change the swing angle of the output rod 212 by rotating the adjustment seat 211, enabling the user to precisely adjust the position and angle of the lever arm according to specific training needs and physical conditions, thereby achieving the best training effect. Furthermore, the adjustment seat 211 is provided with interval holes 21101 around its rotation axis. The vertical locking component 220 includes an elastic element 221 and a locking pin 222. The elastic element 221 connects to and drives the locking pin 222 to insert into the interval holes 21101. The design of the interval slots allows for precise locking at different preset angle positions, not only facilitating quick positioning of the desired angle by the user but also enhancing the stability of the equipment during use. When the locking pin 222 is inserted into the stop hole 21101, the preload provided by the elastic element 221 ensures that the lever arm is firmly locked in the selected position, preventing accidental movement and thus improving the overall safety performance. The elastic element 221 is commonly a spring.

[0054] Refer to Figure 2 and Figure 3In some embodiments of this utility model, a fixed sleeve 110 is fixedly connected to the frame 100. A locking post 222 is slidably disposed within the fixed sleeve 110 in a vertical direction. An elastic element 221 is sleeved on the locking post 222, with one end of the elastic element 221 abutting against the fixed sleeve 110 and the other end pressing against the locking post 222. It is readily understood that by placing the locking post 222 within the fixed sleeve 110 and allowing it to slide vertically, the stability and accuracy of the locking post 222 when inserting and withdrawing from the stop hole 21101 are ensured. The fixed sleeve 110 provides a guiding function, preventing the locking post 222 from shifting or tilting during movement, thereby ensuring that each locking and unlocking operation is performed accurately. This design not only improves the reliability and stability of the equipment but also extends the service life of the locking post 222 and reduces the risk of failure due to wear or deformation. Secondly, the design of the elastic element 221, which is fitted onto the locking post 222 with one end abutting against the fixed sleeve 110 and the other end pressing against the locking post 222, provides an effective pre-tightening mechanism. This pre-tightening force ensures that the locking post 222 is always pushed into the stop hole 21101 in its natural state, ensuring that even under external impact or vibration, the locking post 222 remains in the stop hole 21101, preventing accidental dislodgement. This not only enhances the safety of the equipment but also increases user confidence, especially during high-intensity training, allowing users to perform various movements with greater peace of mind without worrying about the lever arm suddenly loosening or shifting. Furthermore, the elastic element 221 also provides a certain degree of buffering and shock absorption. When the locking post 222 is subjected to external impact or the lever arm is subjected to a large load, the elastic element 221 can absorb some energy, reducing the direct impact on mechanical components and thus protecting the locking post 222 and the stop hole 21101 from damage. This buffering effect not only extends the overall lifespan of the equipment but also reduces maintenance costs and frequency, enabling the equipment to operate stably for a long period.

[0055] The dual-arm assembly according to an embodiment of the present invention includes a dual-end unlocking structure according to an embodiment of the present invention. The dual-arm assembly employs the aforementioned dual-end unlocking structure, connecting the control handle 310 to two vertical locking components 220 via a connecting rope 330 transmission mechanism. This enables simultaneous control of two horizontal adjustment components 210 by a single control handle 310. This design greatly simplifies the user's operation steps when adjusting the arm position or angle, improving adjustment efficiency. In use, the user only needs to pull or push a single control handle 310 to easily unlock and relock the arm, avoiding the inconvenience and cumbersome process of traditional knob locking methods. Furthermore, since the control handle 310 can be operated using the entire palm, rather than just the fingertips, this not only increases the contact area during operation but also reduces finger pressure, making it particularly user-friendly for users with less hand strength or limited dexterity. Overall, this simple and efficient unlocking mechanism not only improves user convenience and comfort but also reduces the complexity of equipment maintenance, providing users with a safer, more reliable, and easier-to-operate solution.
