Description

Technical Field

[0001] The utility model relates to the technical field of sports and fitness, in particular to a multi-freedom rope skipping handle and a rope skipping. Background Art

[0002] Rope skipping is a common fitness product in daily life. It can be used by students for physical exercise and for professional competitive games. Existing skipping ropes include cotton skipping ropes, plastic skipping ropes, fiber-woven skipping ropes, steel wire skipping ropes, and bamboo skipping ropes. The rope handles are also divided into plastic handles, wooden handles, and counting handles. These skipping ropes have the following problems: cotton skipping ropes are soft and can basically solve the problem of whipping during the skipping process. However, since cotton skipping ropes are light, if a suitable specific gravity is to be configured, the rope thickness will be increased, thereby increasing the jumping height of the feet and reducing the skipping speed and pass rate. Other hard skipping ropes, although thinner ropes can be made due to their heavy specific gravity, the hard ropes are prone to twisting and knotting when rotating relative to the handles, which also reduces the skipping pass rate. They are also prone to whipping due to twisting and failure to pass. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a skipping rope handle with high rotational freedom and not prone to twisting of the rope body, as well as a skipping rope with high rotational freedom, not prone to whipping and high pass rate.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a multi-degree-of-freedom rope skipping handle, comprising a handle body, and also comprising: a connecting end connected to the rope body, the connecting end comprising a hollow hemispherical shell, at least one or more levels of hollow spherical connecting elbows for relative rolling and sliding sleeve connections are arranged in the hollow hemispherical shell, the multi-level hollow spherical connecting elbows comprising an innermost ball elbow and an intermediate ball elbow, the diameter of the open cross-section of the intermediate ball elbow decreases from the outer layer to the inner layer, and is larger than the open cross-section diameter of the innermost ball elbow, and the open cross-section of the innermost ball elbow is connected to the rope body.

[0005] Preferably, the diameter of the open section of the hollow spherical connecting elbow is smaller than the diameter of the spherical body, and the length of a line passing through the center of the sphere and connecting the center of the open section and a point on the spherical surface is greater than the radius of the spherical body.

[0006] A skipping rope comprises the multi-degree-of-freedom skipping rope handle described above, and further comprises a first rope body and a second rope body, wherein one end of the first rope body is connected to the innermost ball elbow, and the other end is connected to the second rope body.

[0007] Preferably, the softness of the first rope body is greater than the softness of the second rope body, and the specific gravity of the second rope body is greater than the specific gravity of the first rope body.

[0008] Preferably, the first rope body is a soft cotton rope.

[0009] Preferably, it further comprises a first joint and a second joint connecting the first rope body and the second rope body, wherein the second joint of the first joint is connected by a threaded connection or a snap connection.

[0010] Preferably, an accommodating cavity is provided in the first joint and / or the second joint.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The innermost ball elbow of the handle of the present invention can form a multi-level spherical relative rolling and sliding motion relative to the middle ball elbow and the spherical hollow hemispherical shell. The rope connection end of the conventional handle is generally a fixed direction of rope output, that is, it follows the rope output direction of the handle. Even if a rotating bearing is set in the handle, it can only rotate within a small range of the rope output circle of the handle, and the degree of freedom is relatively low. In addition, when skipping rope, it is impossible for a person's wrist to maintain a 90-degree angle with the arm for a long time, and then it is difficult for the handle to maintain a 90-degree angle with the arm. Therefore, the direction of the rotational force emitted by the arm cannot be highly consistent with the direction of rope rotation, causing rope rotation obstruction, jamming, etc., reducing the pass rate. The multi-degree-of-freedom handle of the present application can make the rope output direction not completely follow the direction of the handle. It can deviate from the handle direction under the action of the rotational force and follow the direction of the rotational force, reduce torque, maximize the smooth transmission of torsional force, make the rope more stable, have a higher pass rate, and be more friendly to effective physical energy consumption.

[0013] The skipping rope of the present invention transmits rotational force through a handle with multiple degrees of freedom and smoother rotation, further optimizes the rotational freedom through the softer first rope body, and further reduces the twisting and knotting of the rope body; and through the subsequent second rope body with a larger specific gravity, increases the rotational centrifugal force, reduces the cross-sectional diameter of the rope body, reduces the jumping height, improves the pass rate and reduces energy consumption.

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, purpose and efficacy of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without making creative work are all within the scope of protection of the present invention. The experimental methods in the following embodiments, unless otherwise specified, are all conventional methods, and the materials, reagents, etc. used in the following embodiments, unless otherwise specified, can be obtained from commercial channels.

[0018] Example 1

[0019] like Figure 1 As shown, a multi-degree-of-freedom rope skipping handle 1 includes a handle body 101 and a connecting end 102 for connecting to a rope body 2. The connecting end 102 includes a hollow hemispherical shell 3. A three-stage hollow spherical connecting elbow 4 is provided within the hollow hemispherical shell 3, which is connected by relative rolling and sliding sleeves. The three-stage hollow spherical connecting elbow 4 includes an innermost spherical elbow 401 and two intermediate spherical elbows 402. The diameter of the open cross-section of the intermediate spherical elbow 402 decreases from the outer layer to the inner layer and is larger than the open cross-section diameter of the innermost spherical elbow 401. The open cross-section of the innermost spherical elbow 401 is connected to the rope body 2. The innermost spherical elbow 401 of the handle can form a multi-level spherical relative rolling and sliding motion relative to the intermediate spherical elbow 402 and the spherical hollow hemispherical shell 3. The multi-degree-of-freedom handle allows the rope to be released in a direction that's not entirely aligned with the handle itself. Under rotational force, it can deviate from the handle's direction and instead follow the direction of the force, reducing torque and maximizing the smoothest transmission of torsional force. This results in a more stable rope, a higher throughput rate, and improved energy efficiency. The rope is connected only to the open end of the innermost ball elbow, allowing for better transmission of rotational force after optimized degrees of freedom, resulting in smoother use.

[0020] In other specific embodiments, the diameter of the open cross-section of the hollow spherical connecting elbow 4 is smaller than the diameter of the spherical body, and the length of the line passing through the center of the sphere and connecting the center of the open cross-section and a point on the spherical surface is greater than the radius of the spherical body. The multiple layers of hollow spherical connecting elbows 4 form a mostly enclosed shape, and open cross-section circles with larger diameters remain, so that the angles and amplitudes of relative rotation between the multiple layers of hollow spherical connecting elbows 4 are larger, and the innermost layer of the ball elbow has a larger rotation angle and amplitude, forming a larger degree of rotation freedom. Therefore, the handle can rotate more flexibly, and when the handle body is not parallel to the ground, the innermost layer of the ball elbow 401 can also make the output end of the rope body as parallel to the ground as possible under the adjustment of the multiple layers of hollow spherical connecting elbows 4, so as to better output the rotational force and reduce the twisting and knotting of the rope body.

[0021] Example 2

[0022] like Figure 2 As shown, a skipping rope comprises the multi-degree-of-freedom skipping rope handle 1 described in Example 1, and further comprises a first rope body 201 and a second rope body 202. One end of the first rope body 201 is connected to the innermost ball elbow 401, and the other end is connected to the second rope body 202. The first rope body 201 is a soft cotton rope, and the second rope body 202 is a rubber rope. The first rope body 201 is softer than the second rope body 202, and the specific gravity of the second rope body 202 is greater than the specific gravity of the first rope body 201. The combination of two rope bodies 2 with different characteristics effectively reduces rotational force loss, the easy twisting and tangling of the rope body, and the difficulty of passing the rope over the feet and the easy whipping of people.

[0023] In other specific embodiments, two ropes 2 with different characteristics are movably connected by a first joint 501 and a second joint 502. Specifically, the first joint 501 and the second joint 502 are connected by a threaded connection or a snap connection. This facilitates the disassembly and storage of the ropes 2 and the replacement of ropes 2 of different lengths or types, making the jump rope more diverse and adaptable to more scenarios.

[0024] In other specific embodiments, a cavity is provided in the first connector 501 and / or the second connector 502 to accommodate a portion of the rope body, thereby facilitating adjustment of the rope body length.

[0025] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0026] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
