Description

Technical Field

[0001] This utility model relates to the field of sports equipment, and in particular to a rotor device for jump ropes and a jump rope. Background Technology

[0002] Current jump ropes generally consist of two handles for gripping and a rope connecting the two handles. During exercise, the rope rotates around the body, thus completing the jump rope motion. The two ends of the rope are usually mounted to the handles via a rotor device (or rotating device). During jump rope, the rotor device rotates at high speed, experiencing axial and radial forces along the handles. The rotor device experiences high stress, and if its structural strength is not high, it is prone to bending and breakage. Therefore, there is an urgent need for a jump rope rotor device and jump rope that can enhance structural strength to overcome these shortcomings. Utility Model Content

[0003] The first objective of this invention is to provide a rotor device for a jump rope that helps to strengthen the structure.

[0004] The second objective of this invention is to provide a jump rope having the aforementioned rotor device.

[0005] To achieve the above objectives, the present invention provides a rotor device for a jump rope, which is rotatably mounted on the handle of the jump rope. The rotor device includes a rotating shaft, a rope, an elastic element, and a locking assembly. The rotating shaft has mounting cavities extending through both ends. One end of the rope forms a mounting end, passing through the mounting cavity and extending beyond it. The locking assembly locks the mounting end to prevent the rope from exiting the mounting cavity. The locking assembly is located on one side of the end of the rotating shaft. The elastic element is inserted into the mounting cavity and fitted onto the rope. Preferably, the elastic element cannot slide axially along the axis of rotation within the mounting cavity.

[0006] Preferably, the elastic element is a spring.

[0007] Preferably, the elastic element is clamped together by the rope and the rotating shaft in the mounting cavity.

[0008] Preferably, the rotating shaft is thickened at one end near the locking component to form a stop end, and the locking component engages with the stop end.

[0009] Preferably, the locking assembly includes an inner buckle and an outer sleeve. The inner buckle has a rope-threading channel for a rope to pass through, and the rope-threading channel is configured to be variable in size. The outer sleeve is fitted over the inner buckle and the rope-threading channel is arranged to retract so that the inner buckle locks the rope.

[0010] Preferably, one of the outer sleeve and the stop end forms a plurality of engaging protrusions, and the other of the outer sleeve and the stop end forms a plurality of engaging notches, with the engaging protrusions engaging into the engaging notches.

[0011] Preferably, the rotor device of this utility model also includes a rotor cover, the end of the rotating shaft away from the locking component is a fixed end, the rotor cover is provided with a through hole, the rotor cover is fitted onto the fixed end, the through hole is directly opposite the mounting cavity, and the rope also passes through the through hole.

[0012] To achieve the second objective mentioned above, this utility model provides a jump rope, which includes a handle and the aforementioned jump rope rotor device. The jump rope rotor device is installed inside the handle, and the rotation of the rotor device is achieved by rotating the handle via bearings.

[0013] Preferably, the jump rope of this invention also includes a grip structure portion that is covered by the handle, and the grip structure portion is provided with anti-slip ridges.

[0014] Compared with existing technologies, the rotor device of this utility model includes a rotating shaft, a rope, an elastic element, and a locking assembly. The rotating shaft has mounting cavities extending through both ends. One end of the rope forms the mounting end, passing through the mounting cavity and extending beyond it. The locking assembly locks onto the mounting end to prevent the rope from slipping out of the mounting cavity. The locking assembly is located on one side of the end of the rotating shaft. The elastic element is installed in the mounting cavity and fitted onto the rope. In this utility model, the swinging rope drives the rotating shaft to rotate on the handle. The rotating shaft provides positioning, support, and force on the rope. Because an elastic element is installed inside the rotating shaft, located between the rotating shaft and the rope, the elastic element can deform and adjust accordingly with the movement of the rope, bearing a certain amount of force. Simultaneously, the elastic element also strengthens the structural strength of the rotating shaft, effectively reducing the possibility of bending or breakage. The locking assembly also prevents the rope from being pulled out. Furthermore, this structural design, using a mating installation method, facilitates processing. Attached Figure Description

[0020] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0021] like Figures 1 to 5 As shown, this utility model discloses a jump rope 100, including a handle 10 and a rotor device 20. The rotor device 20 is rotatably mounted on the handle 10. This utility model mainly improves the rotor device 20 of the jump rope, which will be described in detail below.

[0022] like Figures 1 to 5 As shown, the rotor device 20 of this invention includes a rotating shaft 21, a rope 22, an elastic element 23, and a locking assembly 24. The rotating shaft 21 has mounting cavities 211 extending through both ends. One end of the rope 22 forms a mounting end 221, passing through the mounting cavity 211 and extending out of it. The locking assembly 24 locks to the mounting end 221 to prevent the rope 22 from exiting the mounting cavity 211. The locking assembly 24 is located on one side of the end of the rotating shaft 21. The elastic element 23 is inserted into the mounting cavity 211 and fitted onto the rope 22. In this invention, the swinging rope 22 drives the rotating shaft 21 to rotate on the handle 10. The rotating shaft 21 provides positioning, support, and force application for the rope 22. Because an elastic element 23 is installed inside the rotating shaft 21, located between the rotating shaft 21 and the rope 22, the elastic element 23 can deform and adjust accordingly with the movement of the rope 22, bearing a certain amount of force. At the same time, the elastic element 23 can also strengthen the structural strength of the rotating shaft 21, thereby effectively reducing the possibility of bending or breaking of the rotating shaft 21. The locking component 24 also prevents the rope 22 from being pulled out. In addition, this structural design, which uses a mating method for installation, facilitates processing.

[0023] like Figures 1 to 5 As shown, the elastic element 23 cannot slide axially along the rotation shaft 21 within the mounting cavity 211 to enhance its installability and ensure its proper function in bearing loads and improving structural strength. Preferably, the elastic element 23 is a spring, such as an alloy spring, but not limited to it, to ensure sufficient load-bearing capacity and support. Furthermore, the elastic element 23 is clamped by both the rope 22 and the rotation shaft 21 within the mounting cavity 211 to prevent loosening. Additionally, the height of the mounting cavity 211 is A, and the length of the elastic element 23 is B, where B is at least 40% greater than A, ensuring the elastic element 23 has sufficient capacity to bear loads and improve structural strength.

[0024] like Figures 1 to 5As shown, the end of the rotating shaft 21 near the locking assembly 24 is thickened to form a stop end 212. The rotating shaft 21 is mounted to the handle 10 via bearings 30, allowing the rotating shaft 21 to rotate smoothly on the handle 10. The bearings 30 are located on one side of the stop end 212. Preferably, two sets of bearings 30 are fitted on the rotating shaft 21, but this number is not limited.

[0025] like Figures 1 to 5 As shown, the locking assembly 24 includes an inner buckle 241 and an outer sleeve 242. The inner buckle 241 has a rope-threading channel through which the rope 22 can pass. The rope-threading channel is variable in size. The outer sleeve 242 is fitted over the inner buckle 241, causing the rope-threading channel to retract, so that the inner buckle 241 engages with the rope 22. When the outer sleeve 242 is disengaged from the inner buckle 241, the rope-threading channel expands, and the inner buckle 241 no longer holds the rope 22. At this time, the locking assembly 24 can be moved to the corresponding position by the rope 22. Existing structures can be used for the inner buckle 241 and the outer sleeve 242; their structures are not described in detail. Furthermore, in the embodiments provided by this utility model, the outer sleeve 242 has a locking protrusion 2421, and the stop end 212 has a plurality of locking notches 2121. The locking protrusion 2421 is engaged in the locking notches 2121. At this time, when the rotating shaft 21 rotates, it can synchronously drive the locking component 24 to rotate, avoiding abnormal noise caused by asynchronous movement of the two. Of course, the locking protrusion 2421 can also be provided on the stop end 212, and the locking notches 2121 can be provided on the outer sleeve 242.

[0026] To improve the aesthetics of the jump rope 100, the rotor device 20 of this invention also includes a rotor cover 25. The end of the rotating shaft 21 furthest from the locking component 24 is a fixed end 213. The rotor cover 25 has a through hole 251. The rotor cover 25 is fitted onto the fixed end 213, and the through hole 251 is directly opposite the mounting cavity 211. The rope 22 also passes through the through hole 251. Preferably, the rotor cover 25 is fixed to the fixed end 213 by ultrasonic fixing, but it is not limited to this method.

[0027] like Figures 1 to 5 As shown, the jump rope 100 of this utility model also includes a grip structure 40 that is fitted over the handle 10, and the grip structure 40 is provided with anti-slip textures 41. Preferably, the grip structure 40 can be made of a soft rubber material, such as rubber or silicone, to improve the user experience. Preferably, the anti-slip textures 41 can be designed as a fingerprint-like structure, allowing the thumb to grip the handle 10 better.

[0028] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall fall within the scope of the present utility model.
