However, the internal structure of the cable retainer is generally complex, and the disassembly and assembly process is not only time-consuming but also prone to damaging the equipment, causing considerable inconvenience to users and maintenance personnel. Furthermore, existing disassembly methods require significant time and effort, reducing the efficiency of equipment maintenance and repair. Moreover, the complex disassembly and assembly steps increase the workload of operators, hindering rapid equipment maintenance and upkeep.

[0004] Therefore, how to solve the problem of time-consuming and laborious disassembly and assembly of the cover caused by the steel cable fixing sleeve is an urgent problem to be solved by those skilled in the art. Utility Model Content

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; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0038] The core of this invention is to provide a quick-disassembly mechanism that allows for the rapid assembly and disassembly of the cover 2 without removing the steel cable fixing sleeve 10, reducing labor intensity and saving time and effort. Another core aspect of this invention is to provide fitness equipment incorporating the aforementioned quick-disassembly mechanism, thereby improving the efficiency of equipment installation and maintenance.

[0039] Please refer to Figure 1 , Figure 2 and Figure 3 A quick-release mechanism includes a frame 1, a cover 2, and a quick-release mechanism 3.

[0040] Specifically, the frame 1 serves as the foundation of the entire mechanism, providing stable support. The cover 2 is detachably mounted on the frame 1, and the quick-release mechanism 3 is detachably mounted on the cover 2. The quick-release mechanism 3 has a through hole 311 for the steel cable fixing sleeve 10 to pass through, allowing the steel cable fixing sleeve 10 to pass directly through the quick-release mechanism 3. This enables the cover 2 to be quickly disassembled and assembled without removing the steel cable fixing sleeve 10, thus shortening the disassembly and assembly time and improving work efficiency. A rotatable limiting structure 4 is provided at the through hole 311 to block the through hole 311, so that the through hole 311 can only be passed through by the steel cable 20 connected to the steel cable fixing sleeve 10. The rotatable design of the limiting structure 4 makes the opening and closing of the through hole 311 more flexible and reliable, so that the steel cable fixing sleeve 10 will not come off the quick release mechanism 3 during normal use. When it is necessary to remove the cover 2, it can be done without removing the steel cable fixing sleeve 10. The through hole 311 can be opened and closed by rotating the limiting structure 4. The operation process is simple and intuitive, without complicated tools and steps. This allows operators to easily complete the disassembly and assembly of the cover 2, reducing labor intensity and saving time and effort.

[0041] The cover 2 is connected to the frame 1 via multiple mounting screws 5. The cover 2 has a rectangular structure, and its four corners are secured to the frame 1 with four mounting screws 5. This multi-point fixing method not only ensures a firm and reliable connection between the cover 2 and the frame 1, effectively preventing loosening or detachment due to vibration or other external forces, but also extends the service life of both the cover 2 and the frame 1 through evenly distributed force. The rational arrangement of the four screws ensures the cover 2 remains stable during equipment operation, providing a solid guarantee for the safe operation of the equipment. One end of the steel cable 20 is fixed to the steel cable fixing sleeve 10, and the other end passes through the quick-release mechanism 3 and the cover 2 before being installed inside the frame 1. This ensures the stability and reliability of the steel cable 20 in transmitting force, reducing uneven force transmission caused by loose connections.

[0042] It should be noted that the through hole 311 of the quick-release mechanism 3 is designed to allow the steel cable 20 to pass through smoothly, while the rotatable limiting structure 4 at the through hole 311 blocks the through hole 311 when needed, ensuring that the steel cable fixing sleeve 10 will not come out accidentally. This not only simplifies the disassembly and assembly steps, but also reduces the risk of wear and damage caused by frequent disassembly and assembly of the steel cable fixing sleeve 10, and greatly improves the maintenance efficiency and service life of the equipment.

[0043] The quick disassembly mechanism designed in the above manner can quickly disassemble and assemble the cover 2 without disassembling the steel cable fixing sleeve 10. Its structure is simple, its operation is convenient, and it significantly saves time and labor costs.

[0044] Traditional methods require disassembling the steel cable fixing sleeve 10 before removing the machine cover 2, a complex and time-consuming process. However, the quick-release mechanism described above eliminates the need to disassemble the steel cable fixing sleeve 10, allowing direct assembly and disassembly of the machine cover 2. This significantly reduces assembly and disassembly time and improves work efficiency, especially for fitness equipment requiring frequent maintenance and repair. For example, in commercial fitness venues, rapid maintenance and restoration of equipment can effectively reduce economic losses due to equipment repairs. Since the steel cable fixing sleeve 10 does not need to be disassembled, operators do not need to disassemble the complex structure of the sleeve, simplifying the operation process. This not only reduces operational difficulty but also reduces the risk of equipment damage due to improper operation, allowing ordinary users or non-professional maintenance personnel to easily assemble and disassemble the machine cover 2. This design improves the user-friendliness of the equipment and enhances the user experience.

[0045] Furthermore, traditional disassembly and assembly methods require specialized tools and skills, and are prone to damaging components during the process, increasing maintenance costs. The aforementioned quick-disassembly mechanism simplifies the disassembly and assembly process, reduces reliance on specialized tools and skills, and lowers the risk of equipment damage due to improper disassembly and assembly, thereby reducing equipment maintenance costs. Since there is no need to disassemble the steel cable fixing sleeve 10, frequent operations on the steel cable fixing sleeve 10 are reduced, lowering the risk of damage to the steel cable fixing sleeve 10 due to improper operation during disassembly and assembly. It can be widely used in integrated machines and various force equipment.

[0046] Please refer to Figure 3 and Figure 4 The limiting structure 4 includes two limiting pieces 41. The two limiting pieces 41 are connected to the quick-release mechanism 3 by fixing screws 42. The limiting pieces 41 rotate around the fixing screws 42. In the limiting state, there is a gap between the two limiting pieces 41 for the steel cable 20 to pass through. In the disassembly state, there is a space between the two limiting pieces 41 for the steel cable fixing sleeve 10 to pass through.

[0047] It should be noted that the two limiting plates 41 are connected to the quick-release mechanism 3 by fixing screws 42. The fixing screws 42 not only serve as a connection but also act as the rotation center of the limiting plates 41, allowing them to rotate and making their movement more flexible, enabling quick switching between different states. The gap can be adjusted in different states by changing the rotation angle. This rotation mechanism is simple, efficient, and easy to operate, requiring no complicated tools or steps. In the limiting state, a gap is left between the two limiting plates 41 for the steel cable 20 to pass through, ensuring that the steel cable 20 can stably pass through the limiting structure 4 during equipment operation without any obstruction. Simultaneously, the shape and position design of the limiting plates 41 effectively prevents the steel cable fixing sleeve 10 from accidentally coming off, ensuring the safety and reliability of the equipment. In the disassembly state, rotating the limiting plates 41 quickly opens enough space for the steel cable fixing sleeve 10 to pass smoothly, making the disassembly and installation of the cover 2 faster and greatly improving work efficiency.

[0048] The limiting plate 41 can quickly switch between the limiting state and the disassembly state with a simple rotation operation, reducing disassembly and assembly time and improving equipment maintenance efficiency. The design of the limiting structure 4 simplifies the disassembly and assembly process, requiring no complicated tools or steps, allowing ordinary users or non-professional maintenance personnel to easily disassemble and assemble the cover 2.

[0049] In the above case, the limiting piece 41 includes a connecting part and a blocking part, which are integral structures. The connecting part is provided with a groove for installing the fixing screw 42. The groove is provided with a threaded hole for the fixing screw 42 to pass through. The end of the fixing screw 42 is provided with a limiting nut 43, which is located at the bottom of the quick release mechanism 3.

[0050] Understandably, the connecting part of the limiting plate 41 is connected to the quick-release mechanism 3 via the fixing screw 42, ensuring a firm and reliable connection between the limiting plate 41 and the quick-release mechanism 3. A limiting nut 43 is provided at the end of the fixing screw 42, located at the bottom of the quick-release mechanism 3, further enhancing the stability of the connection and preventing the fixing screw 42 from loosening or falling off during use. The fixing screw 42 passes through a threaded hole so that its head is located within a countersunk groove, making the end face of the limiting plate 41 flush, ensuring the aesthetics of the limiting plate 41, and also making the installation of the fixing screw 42 more stable. The blocking part of the limiting plate 41 allows for quick switching between the limiting state and the disassembly state. Through a simple rotation operation, the limiting plate 41 can quickly switch from the limiting state to the disassembly state, greatly improving the convenience of operation.

[0051] The connecting part and the blocking part are designed as a single unit, which increases the overall strength of the limiting piece 41 and reduces structural loosening or damage caused by weak connections between the two parts, ensuring the stability of the limiting piece 41 during long-term use. The integrated design reduces assembly steps in the manufacturing process, lowering production costs. The one-piece molding process allows for the rapid production of high-quality limiting pieces 41, improving production efficiency. However, in practical applications, the connection method between the connecting part and the blocking part is not limited, as long as synchronous rotation is achieved.

[0052] Furthermore, the two limiting pieces 41 are arranged symmetrically about the center of the through hole 311.

[0053] It should be noted that the two limiting plates 41 are symmetrically arranged about the center of the through hole 311, which makes the force on the entire quick release mechanism 3 more uniform, so as to effectively reduce the structural deformation or damage caused by uneven force, and ensure the stability and reliability of the quick release mechanism 3 in long-term use.

[0054] In the above embodiment, the quick-release mechanism 3 is provided with a limiting groove for installing the limiting piece 41.

[0055] Understandably, the design of the limiting groove provides a precise installation position for the limiting piece 41, ensuring a more stable and accurate installation of the limiting piece 41 on the quick-release mechanism 3. This effectively reduces structural loosening or deformation caused by inaccurate installation, thus improving the overall stability of the quick-release mechanism 3. The limiting groove design simplifies the installation process of the limiting piece 41; operators only need to place the limiting piece 41 into the limiting groove to quickly complete the installation, improving installation efficiency.

[0056] Based on the above embodiments, a limiting component for limiting the rotation angle of the limiting piece 41 is provided between the limiting piece 41 and the quick-release mechanism 3.

[0057] It should be noted that the limiting component can precisely control the rotation angle of the limiting piece 41, ensuring that the limiting piece 41 can accurately switch between the limiting state and the disassembly state, so as to effectively prevent equipment failure caused by inaccurate rotation angle, improve the reliability and safety of the equipment, and ensure the consistency of each operation.

[0058] In one feasible implementation, the limiting component includes a limiting protrusion and a limiting groove. A limiting protrusion is provided on the bottom end face of the limiting piece 41, and a limiting groove that mates with the limiting protrusion is provided on the top end face of the quick-release mechanism 3. When it is necessary to open the limiting piece 41 to make room for the disassembly of the steel cable fixing sleeve 10, the limiting nut 43 is loosened and the fixing screw 42 is rotated so that the limiting nut 43 is pressed against the bottom end face of the quick-release mechanism 3, and the limiting piece 41 is lifted. At this time, the limiting piece 41 is rotated. When the limiting protrusion on the limiting piece 41 engages with the limiting groove on the quick-release mechanism 3 to limit the position of the limiting piece 41, the steel cable fixing sleeve 10 can pass through the space between the two rotated limiting pieces 41.

[0059] In another feasible implementation, the limiting component includes two magnets for limiting, which are respectively set on the bottom end face of the limiting plate 41 and the top end face of the quick-release mechanism 3. When it is necessary to open the limiting plate 41 to make room for disassembly of the steel cable fixing sleeve 10, the limiting nut 43 is loosened and the fixing screw 42 is rotated so that when the limiting nut 43 is pressed against the bottom end face of the quick-release mechanism 3, the limiting plate 41 is lifted. At this time, the limiting plate 41 is rotated. When the magnet on the limiting plate 41 and the magnet on the quick-release mechanism 3 are attracted to each other, it indicates that the limiting plate 41 has been rotated into place. At this time, the steel cable fixing sleeve 10 can be passed through the space between the two limiting plates 41 after they have been rotated into place.

[0060] In practical applications, there are no restrictions on the specific structure and setting method of the limit component, as long as the above-mentioned technical effects can be achieved.

[0061] Please refer to Figure 3 , Figure 4 and Figure 5 The quick-release mechanism 3 includes a quick-release fixing frame 31, which is connected to the cover 2 via fastening screws 32. A limiting structure 4 is rotatably mounted on the quick-release fixing frame 31. The quick-release fixing frame 31 is cylindrical, with a through hole 311 located in its center. The size of the through hole 311 is larger than the size of the steel cable fixing sleeve 10. Furthermore, the quick-release fixing frame 31 has multiple outwardly extending connecting ears 312 circumferentially connected to the cover 2 via fastening screws 32.

[0062] It should be noted that the quick-release mounting bracket 31 is connected to the cover 2 via multiple fastening screws 32. This multi-point connection method ensures a firm and reliable connection between the quick-release mounting bracket 31 and the cover 2. The even distribution of the multiple fastening screws 32 ensures a uniform distribution of connection force, reducing damage to the connection points caused by excessive force at a single point, and extending the service life of the cover 2 and the quick-release mounting bracket 31. The design of the quick-release mounting bracket 31 makes the disassembly and assembly of the cover 2 simpler. By loosening or tightening the fastening screws 32, the disassembly and assembly of the cover 2 can be completed quickly, greatly improving the convenience and efficiency of operation. The quick-release mounting bracket 31 has a cylindrical structure, with a through hole 311 located in the middle of the quick-release mounting bracket 31, making the overall layout of the quick-release mechanism 3 more compact and saving space. The size of the through hole 311 is larger than the size of the steel cable fixing sleeve 10, ensuring that the steel cable fixing sleeve 10 can pass through smoothly, further optimizing the internal layout of the equipment. Multiple connecting lugs 312 are evenly distributed around the quick-release bracket 31, further enhancing the stability of the connection and enabling the quick-release bracket 31 to be evenly distributed when under stress.

[0063] Please refer to Figure 6 and Figure 7 The quick-release mounting bracket 31 has a limiting groove with the same shape as the limiting piece 41 and two threaded holes for installing fixing screws 42. The two limiting pieces 41 are installed in the corresponding limiting grooves of the quick-release mounting bracket 31 by the two fixing screws 42. The limiting nut 43 is installed at the bottom of the fixing screw 42 to prevent the fixing screw 42 from coming out. When the limiting piece 41 is in the limiting state, the opening size between the two limiting pieces 41 is smaller than the size of the steel cable fixing sleeve 10, and the steel cable fixing sleeve 10 cannot pass through at this time. Loosen the fixing screws 42 until the limiting nut 43 is against the bottom of the quick-release mounting bracket 31. At this time, the limiting piece 41 can be lifted and rotated, and the through hole 311 on the quick-release mounting bracket 31 can be exposed. The steel cable fixing sleeve 10 can be easily removed from the through hole 311, which can facilitate the removal or installation of the cover 2.

[0064] Specifically, when it is necessary to remove the cover 2, loosen the limiting nut 43 and loosen the fixing screw 42 to move the fixing screw 42 in the direction of disengaging from the sink until the limiting nut 43 abuts against the bottom of the quick-release fixing bracket 31. The limiting piece 41 is lifted out of the limiting groove. At this time, the limiting piece 41 can be rotated. When rotated to the correct position, the through hole 311 on the quick-release fixing bracket 31 is exposed. At this time, the steel cable fixing sleeve 10 can be smoothly removed from the through hole 311, and then the cover 2 can be easily removed. When it is necessary to install the cover 2, first fix the cover 2 on the frame 1, loosen the limiting nut 43, and loosen the fixing screw 42 to move the fixing screw 42 in the direction of disengaging from the sink until the limiting nut 43 abuts against the bottom of the quick-release fixing bracket 31. Nut 43 abuts against the bottom of quick-release fixing bracket 31, and limiting plate 41 is lifted and disengaged from the limiting groove. At this time, limiting plate 41 can be rotated. When rotated to the position, through hole 311 on quick-release fixing bracket 31 is exposed. At this time, steel cable fixing sleeve 10 can be smoothly inserted through through hole 311. After steel cable fixing sleeve 10 passes through through hole 311, limit plate 41 is rotated back to the initial position. By tightening fixing screw 42, fixing screw 42 is moved towards the sink, driving limiting plate 41 towards the limiting groove. After limiting plate 41 moves into the limiting groove, limiting nut 43 is tightened to fix the position of limiting plate 41. At this time, the gap between the two limiting plates 41 is only for steel cable 20 to pass through.

[0065] In summary, the quick-release mechanism provided by this utility model, through the design of the quick-release fixing bracket 31 and the limiting plate 41, enables the rapid disassembly and installation of the cover 2 without removing the steel cable fixing sleeve 10. This design significantly shortens the disassembly and assembly time, improves the maintenance efficiency of the equipment, and its advantages are even more obvious in fitness equipment that requires frequent maintenance and repair. Through the design of the quick-release fixing bracket 31, the limiting plate 41, and the limiting components, the disassembly and assembly efficiency, safety, and reliability of the fitness equipment are significantly improved, the overall design of the equipment is optimized, maintenance costs are reduced, and the user experience is enhanced.

[0066] In addition to the quick disassembly mechanisms disclosed in the above embodiments, this utility model also provides a fitness equipment including the above-mentioned quick disassembly mechanisms.
