Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to pulley block devices and fitness equipment. Background Technology

[0002] In the fitness industry, some fitness equipment is equipped with pulley systems to enable more exercises and enhance training effects. Under normal training conditions, the pulley system is usually fixed to external structural components (such as pedals or uprights). However, during certain exercises, the pulley system needs to slide back and forth following the user's movements—a process known as motion tracking. To achieve this tracking effect, the pulley system needs a locking mechanism to lock onto the external structural components. However, existing locking mechanisms have significant shortcomings: Firstly, the distinction between unlocked and locked states is not clear enough, making it difficult for users to intuitively determine the current state of the pulley system. This not only affects the user experience but may also lead to improper use due to misjudgment. Secondly, the locking mechanisms on existing pulley systems are relatively complex and inconvenient to operate, causing unnecessary trouble and inconvenience for users. In summary, existing pulley systems present user inconvenience issues. Utility Model Content

[0028] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0029] Please refer to Figures 1 to 4 A pulley block assembly, comprising:

[0030] Pulley mechanism 1;

[0031] Mounting base 2, the pulley block mechanism 1 is rotatably mounted on the mounting base 2, and a limiting guide component 4 is provided on one side of the mounting base 2;

[0032] The locking assembly 3 includes a locking rod 31, a sleeve 32, an operating handle 33, and an elastic element 34. The sleeve 32 is mounted on the mounting base 2. The locking rod 31 passes through the sleeve 32 and the mounting base 2. The locking rod 31 is provided with an operating handle 33. The sleeve 32 is provided with a notch. The elastic element 34 contacts the locking rod 31 and the sleeve 32 or the mounting base 2 so that the operating handle 33 abuts against the guide slope 321 formed at the notch.

[0033] As can be seen from the above description, the beneficial effects of this utility model are as follows: the pulley block device has a simple structure, and the user can unlock and lock the locking component 3 by turning the operating handle 33. The user operation is very convenient. Moreover, the user can clearly see the current status of the pulley block device according to the orientation of the operating handle 33, which reduces user misoperation and greatly facilitates user use.

[0034] Furthermore, the limiting guide component 4 includes a limiting slider.

[0035] As described above, the engagement between the limiting slider and the groove on the external structural component restricts the degree of freedom of the mounting base 2, ensuring that the pulley block can only slide in one direction along the external structural component. Furthermore, this simplifies the structure of the pulley block.

[0036] Furthermore, the limiting guide component 4 includes at least three rollers, which are arranged in two rows, one above the other.

[0037] As can be seen from the above description, using rollers as limiting and guiding components 4 allows the pulley block device to slide more smoothly in one direction of the external structure.

[0038] Furthermore, the pulley block mechanism 1 includes a fixed base 11, on which at least three pulleys 12 are provided, and the at least three pulleys 12 are arranged in two rows, one above the other.

[0039] Furthermore, the mounting base 2 is provided with a clearance opening 21 for avoiding the pulley 12 located in the lower row.

[0040] As can be seen from the above description, a portion of the pulley block mechanism 1 is embedded in the clearance opening 21 of the mounting base 2, which reduces the longitudinal space occupied by the pulley block device. As a pulley block device that is frequently slidable, it is smaller in size and easier to operate.

[0041] Furthermore, the external pull rope passing between the two rows of pulleys 12 contacts each of the pulleys 12 respectively, and the external pull rope is straight after being taut.

[0042] As can be seen from the above description, by setting the height difference between the two rows of pulleys 12, it is possible to avoid the path of the external pull rope passing through the pulley block mechanism 1 from being bent, which would generate additional resistance and cause inaccurate force output.

[0043] Furthermore, the pulley block mechanism 1 is provided with an external component mounting structure 5.

[0044] As described above, the external component mounting structure 5 is used to connect external components such as handles.

[0045] Furthermore, the external component mounting structure 5 includes a socket 51.

[0046] As can be seen from the above description, the plug-in type external component mounting structure 5 can be easily assembled with external components, which facilitates user operation.

[0047] Furthermore, at least one resilient locking pin 52 is provided at the socket 51.

[0048] As can be seen from the above description, the resilient locking pin 52 can easily fix or unlock the external components.

[0049] Fitness equipment, including the aforementioned pulley system.

[0050] Please refer to Figures 1 to 4The first embodiment of this utility model is a fitness device, which includes a pedal and a pulley assembly slidably mounted on the pedal. The pulley assembly includes a pulley mechanism 1, a mounting base 2, and a locking component 3. The pulley mechanism 1 is rotatably mounted on the mounting base 2, and a limiting guide component 4 is provided on one side of the mounting base 2. The locking component 3 includes a locking rod 31, a sleeve 32, an operating handle 33, and an elastic element 34. The sleeve 32 is mounted on the mounting base 2, and the locking rod 31 passes through the sleeve 32 and the mounting base 2, and is rotatable and slidable relative to the mounting base 2. The pedal has a locking hole that matches the end of the locking rod 31. The locking rod 31 is provided with an operating handle 33, and the sleeve 32 is provided with a notch. The elastic element 34 contacts the locking rod 31 and the sleeve 32 or the mounting base 2, so that the operating handle 33 abuts against the guide slope 321 formed at the notch.

[0051] In one or more embodiments, the limiting guide component 4 includes a limiting slider. In this embodiment, the limiting guide component 4 includes at least three rollers arranged in two rows. Optionally, the rollers are concave rollers. The side of the pedal has two linear guide rails spaced apart vertically. The rollers in the upper row contact the upper linear guide rail but not the lower linear guide rail, while the rollers in the lower row contact the lower linear guide rail but not the upper linear guide rail. Of course, in other embodiments, the rollers can also be convex rollers. In this case, a corresponding linear groove can be provided on the slide plate.

[0052] In detail, the pulley block mechanism 1 includes a fixed base 11, which is rotatably connected to the mounting base 2. The fixed base 11 is provided with at least three pulleys 12, which are arranged in two rows. To avoid the pulley block mechanism 1 from causing the external pull rope to bend, preferably, the external pull rope passing between the two rows of pulleys 12 contacts each of the pulleys 12 respectively, and the external pull rope is straight after being taut.

[0053] To reduce the size of the pulley block device, the mounting base 2 is provided with a clearance opening 21 for avoiding the pulley 12 located in the lower row.

[0054] The pulley block mechanism 1 is provided with an external component mounting structure 5. Optionally, the external component mounting structure 5 includes a socket 51. To ensure the fixing effect of the external component mounting structure 5 on the external component, at least one elastic locking pin 52 is provided at the socket 51. In this embodiment, the elastic locking pin 52 is provided on both sides of the socket 51.

[0055] The external component mounting structure 5 is located in the gap between the two pulleys 12 in the upper row.

[0056] In addition, in some fitness equipment, the pulley block device can also be installed on the gantry, in which case the gantry has a positioning hole that cooperates with the locking rod 31.
