Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and more specifically, to a rope rotation mechanism and fitness equipment. Background Technology

[0002] In the field of fitness equipment, ropes, as a key force transmission component, are widely used in various devices. Their main function is to transmit the force applied by the user to the resistance device of the fitness equipment, thereby enabling various exercise movements.

[0003] In existing technologies, most rope outlet seats adopt a fixed design, directly installed on the machine body. While this design provides a certain level of stability, it also significantly restricts the rope's freedom of movement. In practical applications, when a user applies force from different directions, the rope adjusts its angle accordingly. However, due to the fixed position of the rope outlet seat, this change in rope angle cannot be effectively adapted, leading to frequent friction between the rope and the outlet seat. This continuous friction not only accelerates rope wear and reduces its lifespan but also gradually roughens the rope surface, weakening its strength and toughness. Over time, the rope may break, undoubtedly posing a potential safety risk to the user.

[0004] Therefore, how to solve the problems of limited freedom of movement and easy wear of existing ropes is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a rope rotation mechanism, in which the rope can rotate freely according to the direction of the user's force, and can also drive the rope outlet seat to rotate, so that the rope hardly rubs against the rope outlet seat at the rope outlet, thereby extending the service life of the rope.

[0006] Another objective of this invention is to provide a fitness equipment that includes the aforementioned rope rotation mechanism, which can extend its service life.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] 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; 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] The core of this invention is to provide a rope rotation mechanism. The rope 4 can rotate freely according to the user's force direction and can also drive the rope outlet 3 to rotate, so that the rope 4 experiences almost no friction with the rope outlet 31, thereby extending the service life of the rope 4. Another core aspect of this invention is to provide fitness equipment including the aforementioned rope rotation mechanism, which can extend its service life.

[0039] Please refer to Figure 1 A rope rotating mechanism includes a base 1 and a rope outlet 3.

[0040] Specifically, the base 1 is located on the body 2, providing stable support for the whole. The rope outlet 3 has a rope outlet 31 for threading the rope 4, ensuring that the rope 4 can accurately pass through the rope outlet 3. One end of the rope 4 is provided with a connecting part for connecting to the body 2, and the other end is provided with a handle 5 for holding, ensuring the stability of the rope 4 during use. When the user pulls the handle 5, the rope 4 can stably transmit the force applied by the user to the resistance device of the fitness equipment, ensuring that the fitness equipment can work normally and meet the user's exercise needs. The base 1 has a mounting cavity, and the rope outlet 3 is rotatably located in the mounting cavity, allowing the rope 4 to rotate freely according to the direction of the user's force, improving the flexibility of the rope 4. The rope 4 can drive the rope outlet 3 to rotate, so that the rope 4 has almost no friction with the rope outlet 31 at the rope outlet 31, thereby extending the service life of the rope 4.

[0041] The handle 5 features an anti-slip texture. During fitness training, users need to apply force through the handle 5 to pull the rope 4 to complete various exercise movements. The anti-slip texture significantly increases the friction between the handle 5 and the user's hand, thereby enhancing grip stability. Even when hands are sweaty or wet, the anti-slip texture effectively prevents slippage, ensuring that the user can firmly grip the handle 5, apply force stably, and improve the safety and reliability of the exercise.

[0042] The rope rotation mechanism designed in the above manner, through the rotatable design of the rope outlet 3, allows the rope 4 to move freely in different directions. This design significantly reduces wear on the rope 4, extends its service life, and lowers equipment maintenance costs and usage risks. Simultaneously, the mechanism can change angles with the rope 4, improving the flexibility and versatility of the equipment and meeting the diverse needs of different users in different exercise scenarios.

[0043] Please refer to Figure 2 The rope outlet seat 3 is coaxially arranged with the base 1 and is rotatably connected to the base 1. A rolling element 6 is provided between the outer peripheral wall of the rope outlet seat 3 and the inner peripheral wall of the base 1 to make the rope outlet seat 3 rotate along its own axis.

[0044] It should be noted that after the rolling element 6 is installed between the rope outlet seat 3 and the base 1, the rotation of the rope outlet seat 3 is mainly achieved through the rolling element 6. This rolling contact method can significantly reduce the friction between the two. The design of the rolling element 6 allows the rope outlet seat 3 to flexibly adapt to the movement requirements of the rope 4 in different directions. No matter how the user changes the direction of force, the rope outlet seat 3 can smoothly adjust its position through the rolling element 6, ensuring that the rope 4 is always in the optimal movement state. This flexibility and adaptability allows the rope rotation mechanism to meet the needs of various fitness equipment and different exercise movements, improving the versatility and applicability of the mechanism. For example, in a multi-gym, users may need to perform stretching, pressing, and other movements at multiple angles and directions. The rolling element 6 allows the mechanism to easily handle these complex movement requirements, providing users with more freedom and diverse exercise options.

[0045] In one feasible implementation, the rolling element 6 is a ball bearing. Ball bearings achieve rotation through the rolling of balls between the inner and outer rings, and their rolling friction coefficient is much lower than that of sliding friction. This low-friction design allows the rope outlet seat 3 to rotate more smoothly, reducing energy loss and improving the mechanism's motion efficiency. During long-term use, the low friction coefficient also significantly reduces component wear and extends the mechanism's service life.

[0046] In a preferred embodiment, the rolling element 6 is a thin-walled angular contact ball bearing. The inner ring of the thin-walled angular contact ball bearing is connected to the rope outlet seat 3, and the outer ring is connected to the base 1. When a thin-walled angular contact ball bearing is used as the rolling element 6, its rolling friction coefficient is only a fraction of the sliding friction coefficient, or even lower. This low-friction design allows the rope outlet seat 3 to rotate more smoothly, reducing energy loss and improving the motion efficiency of the mechanism. The design of the thin-walled angular contact ball bearing results in extremely low frictional force required for startup. This means that even a very small force applied by the rope 4 is sufficient to rotate the rope outlet seat 3. This low starting friction characteristic allows even small movements of the rope 4 in any direction to be effectively transmitted to the rope outlet seat 3, thereby reducing direct friction between the rope 4 and the rope outlet seat 3. For example, when the user gently pulls the rope 4, the rope outlet seat 3 can respond quickly and rotate, avoiding jamming and wear of the rope 4 at the rope outlet 31.

[0047] Furthermore, the thin-walled angular contact ball bearing can withstand radial and axial loads while maintaining low friction and high rotational accuracy. This high-precision rotational performance makes the movement of the rope 4 at the rope outlet 31 smoother and more accurate. Regardless of the change in the direction of rope 4's movement, the rope outlet seat 3 can quickly adjust its position via the thin-walled angular contact ball bearing, ensuring that the rope 4 is always in optimal motion.

[0048] Please refer to Figure 3 , Figure 4 and Figure 5 The rope outlet 31 is elongated, and its width is greater than the diameter of the rope 4. Rolling components 7 are provided at both ends of the rope outlet 31 along its length for rolling within the outlet 31.

[0049] It should be noted that in traditional designs, the movement of rope 4 at the outlet 31 is often accompanied by frequent friction, especially when rope 4 frequently changes direction. This friction leads to increased wear on the surface of rope 4, reducing its service life. In this application, however, the outlet 31 is elongated and wider than the diameter of rope 4. This design provides more space for rope 4 to move, reducing direct contact between rope 4 and outlet 31. More importantly, the outlet seat 3 and base 1 are rotatably connected. When rope 4 moves within the elongated outlet 31, the friction with outlet 31 is mainly concentrated along its length, and this friction is instantaneous—the momentary contact friction occurs when rope 4 drives outlet seat 3 to rotate. Compared to the frequent and continuous friction between rope 4 and outlet 31 in existing technologies, this design effectively reduces friction, significantly reduces the wear of rope 4, and extends its service life.

[0050] Understandably, the rope outlet 31 has rolling components 7 at both ends along its length to reduce friction between the rope 4 and the outlet 31. The rolling components 7 convert the sliding friction between the rope 4 and the outlet 31 into rolling friction, and the coefficient of rolling friction is much lower than that of sliding friction. When the rope 4 moves within the outlet 31, the rolling components 7 effectively disperse the pressure between the rope 4 and the outlet 31, reducing localized wear. Even when instantaneous friction occurs, the rolling components 7 can minimize the impact of this friction, further protecting the rope 4 and reducing wear.

[0051] In one feasible implementation, the rolling component 7 is a rolling wheel, which is rotatably connected to the rope outlet seat 3 via a rotating shaft. The axial direction of the rotating shaft is consistent with the width direction of the rope outlet 31.

[0052] It should be noted that the rolling wheel can rotate smoothly around the axis. When the rope 4 moves along the length of the rope outlet 31, the rope 4 will roll and rub against the rolling wheel, reducing the wear on the surface of the rope 4 caused by friction, thereby extending the service life of the rope 4.

[0053] In another feasible implementation, the rolling component 7 is a ball bearing, which is tumblingly connected to the rope outlet seat 3.

[0054] Understandably, the ball bearing design transforms the sliding friction between the rope 4 and the rope outlet 31 into rolling friction. The coefficient of rolling friction is much lower than that of sliding friction, significantly reducing wear on the rope 4 within the rope outlet 31. Especially when the rope 4 frequently changes direction, the ball bearing effectively disperses the pressure between the rope 4 and the rope outlet 31, reducing localized wear. For example, when a user pulls the rope 4 at different angles, the ball bearing ensures smooth sliding of the rope 4 within the rope outlet 31, reducing surface wear caused by friction and thus extending the rope 4's lifespan.

[0055] In practical applications, there are no restrictions on the specific structure of the rolling component 7, as long as the above-mentioned technical effects can be achieved.

[0056] In a preferred embodiment, the rope outlet 31 and the rope outlet seat 3 are transitioned by a rounded chamfer.

[0057] It should be noted that the rounded chamfer transition design allows the rope 4 to slide more smoothly when entering and exiting the rope outlet 31, reducing direct friction between the rope 4 and the rope outlet seat 3. In traditional designs, the connection between the rope outlet 31 and the rope outlet seat 3 may have sharp edges or right angles, which can cause the rope 4 to rub frequently in these areas, accelerating wear. The rounded chamfer transition design, through a smooth transition, reduces friction on the rope 4 in these areas, thereby extending the service life of the rope 4.

[0058] In the above case, the outer periphery of the base 1 is provided with a plurality of outwardly protruding connecting ears, and the connecting ears are provided with at least one threaded connecting hole. The connecting ears are connected to the body 2 by fixing bolts 8 and threaded connecting holes.

[0059] Understandably, connecting the base 1 to the body 2 via the fixing bolts 8 ensures a secure connection between them, allowing the cable rotation mechanism to remain stable during use. Even under high-intensity stretching and lifting movements, it will not loosen or shift. It also possesses excellent fatigue and vibration resistance, effectively resisting mechanical stress and vibration that may occur during long-term use, reducing the risk of failure due to loose connections. For example, in high-intensity environments such as gyms, the connection method using the fixing bolts 8 ensures the stability of the mechanism, improving the safety and reliability of the equipment.

[0060] In the above embodiment, three connecting ears are provided, evenly distributed on the outer periphery of the base 1, and each connecting ear has three threaded connecting holes arranged in a triangular pattern. The even distribution of the three connecting ears on the outer periphery of the base 1 ensures that the base 1 receives uniform support force in all directions. When the base 1 is subjected to tensile or compressive forces from different directions, the three connecting ears work together to evenly distribute the force across the connection surface between the base 1 and the body 2. This ensures that the mechanism will not shake or loosen during high-intensity exercise, improving the safety and reliability of the equipment. The three threaded connecting holes arranged in a triangular pattern on each connecting ear, when the fixing bolt 8 passes through these holes and connects to the body 2, form a triangular support structure that significantly enhances the connection strength between the base 1 and the body 2. Compared to traditional single-threaded hole or linearly distributed threaded hole connections, this triangularly distributed threaded hole design can withstand greater tensile and compressive forces under the same material and size conditions, effectively reducing the risk of damage due to insufficient strength at the connection points and extending the service life of the equipment. However, in practical applications, there are no restrictions on the number and location of the connecting lugs, or the number and arrangement of the threaded connecting holes.

[0061] In summary, the rope rotation mechanism provided by this utility model allows the rope 4 to rotate by driving the rope outlet seat 3 when the user pulls the handle 5 and changes the direction of force. Even with a small force, the rope outlet seat 3 can rotate smoothly, making the movement of the rope 4 within the rope outlet 31 smoother and reducing direct contact between the rope 4 and the rope outlet seat 3. Even under high-intensity usage environments, wear on the rope 4 is significantly reduced, thereby extending the service life of the rope 4 and lowering equipment maintenance costs.

[0062] In addition to the rope rotation mechanism disclosed in the above embodiments, this utility model also provides a fitness equipment including the above-mentioned rope rotation mechanism.
