Description

FIELD OF THE INVENTION

The present utility model relates to the field of exercising devices, and in particular, to a 360° universal joint jump rope.

BACKGROUND OF THE INVENTION

As an excellent body-building exercise, the rope jump exercise can effectively train people's reaction and endurance capabilities and help maintain people's fitness and body coordination, thereby building a strong and healthy body. The outfit for the rope jump exercise is quite simple, which requires only one rope, light clothes, and a pair of suitable sports shoes. In addition, the rope jump exercise does not need a large space, for which no special venue needs to be rented. Moreover, the number of participants is not limited, and either one person alone or multiple persons together can do the exercise. A common jump rope comprises handles and a rope, and the handles are not provided with any bearing. Consequently, the rope is easily rolled, there is no sense of rhythm, and it is strenuous for people to do the rope jump exercise. Further, there is no length adjusting apparatus. As a result, the jump rope cannot be adjusted according to people's heights, making it inconvenient for people to use. In addition, an insufficient rotational speed of the jump rope is easily caused during rope jump, making rotational speeds of the rope and the handles cancel each other.

DETAILED DESCRIPTION OF THE INVENTION

The following elaborates in detail preferred embodiments of the present utility model with reference to the accompanying drawings, so that a person skilled in the art can understand advantages and features of the present utility model more easily, and the protection scope of the present utility model can be more clearly specified.
Referring to FIG. 1 to FIG. 3, in the embodiments of the present utility model:
A 360° universal joint jump rope comprises a steel wire rope 1. Two ends of the steel wire rope 1 are provided with silicone protective cases 2, and the silicone protective case 2 is used to protect the steel wire rope 1.
An outer wall of the steel wire rope 1 is coated with a wrapper layer. The steel wire rope 1 is connected to two handles 4 by using universal joint connecting buckles 3. The universal joint connecting buckle 3 enlarges an angle between the steel wire rope 1 and the handle 4 when the rope is swung, so that the steel wire rope 1 is more flexible during rotation.
A blocking ring 5 is disposed within the handle 4. Two ends of the blocking ring 5 are adjacently provided with two high speed bearings 6. The two high speed bearings 6 fit the handles 4, so that the two high speed bearings 6 can be fixed inside the handles 4.
An inner diameter of the blocking ring 5 is greater than an inner diameter of the high speed bearing 6, so that the threaded connecting rod 7 is connected to the two high speed bearings 6, which enlarges a rotational speed of the universal joint connecting buckle 3, making it more flexible to swing the rope.
The universal joint connecting buckle 3 passes through the blocking ring 5 and the two high speed bearings 6. The universal joint connecting buckle 3 is fixed by using a fixing nut 8. The fixing nut 8 is used to fix the universal joint connecting buckle 3, so that the universal joint connecting buckle 3 is connected to the handle 4.
The universal joint connecting buckle 3 comprises a first rotating block 9, a second rotating block 10, and a central block 11. The first rotating block 9 and the second rotating block 10 each are symmetrically provided with two connecting plates 12. The first rotating block 9 and the second rotating block 10 are connected to the central block 11 by using the connecting plate 12. A rotating rod is disposed between the connecting plate 12 and the central block 11, so that the first rotating block 9 and the second rotating block 10 can rotate using the central block 11 as a circle center. The first rotating block 9 fits the second rotating block 10, thereby greatly increasing a rotation angle between the steel wire rope 1 and the handle 4.
The first rotating block 9 is provided with a connecting hole 14. The connecting hole 14 is used to connect the handle 4 and the steel wire rope 1.
In this embodiment, an adjusting screw is disposed inside the connecting hole 14. A length of the steel wire rope 1 is adjusted by loosening or tightening the adjusting screw.
The second rotating block 10 is provided with a threaded connecting rod 7. The threaded connecting rod 7 fits the fixing nut 8, so that the universal joint connecting buckle 3 is connected to the handle 4.
In another embodiment, an adjusting block 13 is disposed between the handle 4 and the silicone protective case 2. The adjusting block 13 slides on the steel wire rope 1. The adjusting block is provided with an adjusting screw. The adjusting block 13 is fixed by loosening or tightening the adjusting screw, to adjust the length of the steel wire rope.
Compared with the prior art, for the 360° universal joint jump rope of the present utility model, handles of the jump rope are provided with universal joint connecting buckles, which enlarges motion angles between the handles and the rope when the jump rope is used, making the jump rope more flexible.
The foregoing descriptions are merely embodiments of the present utility model, and are not intended to limit the patent scope of the present utility model. Any equivalent structure or procedure change made based on the specification and the accompanying drawings of the present utility model or by directly or indirectly applying the present utility model to other related technical fields shall fall within the protection scope of the present utility model.
