Abstract
Description
Technical Field
[0001] This utility model relates to the field of jump rope technology, and in particular to a fast self-locking jump rope. Background Technology
[0002] Jumping rope is a healthy form of exercise that takes up little space, requires simple equipment, and allows for a full-body workout, while also providing a comprehensive exercise for the respiratory, cardiac, and cardiovascular systems. Existing jump ropes consist of a rope and handles. The rope is threaded through the handles and knotted, but this knot can easily loosen and come undone during swinging, posing a safety hazard. Furthermore, some existing self-locking adjustment methods, while ensuring rope stability, suffer from complex structures and assembly processes, resulting in high production costs and significant challenges in handle manufacturing. Utility Model Content
[0003] This invention proposes a quick-locking jump rope to solve the problems mentioned in the background art, such as the existing ropes being prone to loosening, leading to unsafe use, and the complex and costly self-locking structure.
[0004] The technical solution of this utility model is implemented as follows:
[0005] A quick-locking jump rope includes a handle, one end of which is rotatably connected to an inner cover, and one end of the inner cover is provided with a conical hole.
[0006] An outer cover that can move along its axis is mounted on the inner cover. The middle part of the outer cover is provided with several claws, and the movable ends of the claws extend into the conical holes.
[0007] When the outer cover moves axially toward the inner cover, the sidewall of the tapered hole can press against the outer wall of the chuck, causing the movable end of the chuck to retract toward the center of the outer cover.
[0008] Preferably, the claw has a locking hook inside, which is located on the inner side of the movable end of the claw.
[0009] Preferably, the inner diameter of the tapered hole increases sequentially from the middle of the inner cover towards the end.
[0010] Preferably, a number of claws are evenly distributed around the center of the outer cover, and the outer wall of the claws matches the taper of the conical hole.
[0011] Preferably, it also includes a rope body, and a plurality of claws are formed around a first through hole for receiving the rope body, the first through hole being connected to a conical hole.
[0012] Preferably, the inner cover has a second through hole at its center, one end of which is connected to the conical hole and the other end of which passes through the end of the inner cover, so that the rope can extend into the second through hole and the inner cavity of the handle.
[0013] Preferably, the inner cover and the outer cover are threaded together.
[0014] Preferably, the inner cover is mounted to the end of the handle via a rotating bearing.
[0015] By adopting the above technical solution, the beneficial effects of this utility model are as follows:
[0016] This invention features a claw and hook structure on the outer cover, which, in conjunction with the conical hole in the inner cover, automatically clamps the rope when the outer cover moves axially relative to the inner cover. This avoids the risk of the rope loosening and falling off in traditional knot-tying methods, thus improving safety and stability. Furthermore, the claw structure is evenly distributed, and the self-locking mechanism formed by the claw and the conical hole is simple and easy to assemble, effectively reducing the production difficulty and manufacturing cost of the jump rope handle.

[0025] 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.
[0026] like Figure 1-5 As shown, a quick-locking jump rope includes a handle 1. In this example, the handle 1 is a hollow sleeve structure. To facilitate a more comfortable grip, the outer surface of the handle 1 can be designed with a textured structure to conform to the grip curve of the human hand. In addition, the surface of the handle 1 can be covered with a rubber layer, a foam layer, or have an anti-slip texture to improve anti-slip performance and grip comfort, preventing slippage due to hand sweat or vigorous exercise during jump rope use, thereby further enhancing the control stability and safety of the jump rope.
[0027] One end of the handle 1 is rotatably connected to an inner cover 4. One end of the inner cover 4 is provided with a conical hole 401. In this example, the inner diameter of the conical hole 401 increases sequentially from the middle of the inner cover 4 to the end, which is a trumpet-shaped structure.
[0028] An outer cover 5 that is movable along its axis is installed on the inner cover 4. A number of claws 501 are provided in the middle of the outer cover 5. The claws 501 are evenly distributed around the center of the outer cover 5. In this example, there are four claws 501.
[0029] Specifically, the claw 501 is integrally connected to the outer cover 5. The claw 501 extends from the end of the outer cover 5 into its interior. One end of the claw 501 connected to the outer cover 5 is a fixed end, and the other end of the claw 501 away from the fixed end is a movable end. The outer cover 5 is made of plastic material, so that the claw 501 can deform to a certain extent when subjected to external force. The movable end of the claw 501 extends into the conical hole 401. The outer wall of the claw 501 matches the taper of the conical hole 401 to apply force to the claw 501 stably. A gap is formed between the claw 501 and the outer cover 5, so that the end of the inner cover 4 with the conical hole 401 can extend into the gap.
[0030] It also includes a rope body 2, and a plurality of claws 501 are formed around a first through hole 503 for receiving the rope body 2, the first through hole 503 being connected to a conical hole 401;
[0031] When the outer cover 5 moves axially toward the inner cover 4, the sidewall of the tapered hole 401 can press against the outer wall of the claw 501, thereby causing the movable end of the claw 501 to retract toward the center of the outer cover 5, so that the movable end of the claw 501 can press and lock the rope 2.
[0032] In this example, to improve the locking effect on the rope 2, a locking hook 502 is provided inside the claw 501, and the locking hook 502 is located on the inner side of the movable end of the claw 501. This can enhance the anti-slip ability of the rope 2 in the clamped state. The locking hook 502 and the rope 2 form a point contact or line contact structure, which can effectively prevent the rope 2 from sliding axially when under force, thereby improving the reliability and durability of the entire self-locking mechanism and ensuring that the jump rope remains stably connected during violent swinging.
[0033] In this example, the inner cover 4 has a second through hole 402 at its center. One end of the second through hole 402 is connected to the conical hole 401, and the other end passes through the end of the inner cover 4, so that the rope 2 can extend into the second through hole 402 and the inner cavity of the handle 1, thereby increasing the adjustment range of the rope 2.
[0034] In this example, the inner cover 4 and the outer cover 5 are threadedly connected. Specifically, the upper end of the inner cover 4 is provided with an external thread, and the inner wall of the outer cover 5 is provided with an internal thread. The two are threadedly engaged. When the two move towards each other, the end of the inner cover 4 can enter the gap area between the claw 501 and the outer cover 5, so that the inner wall of the tapered hole 401 is tightly attached to the outer wall of the claw 501, applying a squeezing force to the claw 501. The claw 501 retracts towards the center, thereby locking the rope 2 with the locking hook 502.
[0035] In this example, the inner cover 4 is mounted on the end of the handle 1 via a rotating bearing 3, so that the handle 1 can rotate relative to the rope 2 during rope skipping to avoid the problem of the rope 2 getting tangled.
[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
