Description

Adjustable skipping rope handle connecting piece

Technical Field

The utility model relates to a sport equipment technical field especially relates to a rope skipping handle connecting piece with adjustable.

Background

The popularity of rope skipping at competitive speed, under the record 220 of 30 seconds world Giniss rope skipping, the world frightens the Chinese speed, and people pay more and more attention to rope skipping while building body. Because the competitive skipping rope is developed relatively late in China, the skipping rope structure is still more copied to foreign products, and the independent research and development are started in recent years.

The skipping rope handle with a built-in single bearing and the skipping rope handle with a built-in double bearing are commonly used at present. The rope skipping handle is internally provided with a single bearing, the middle shaft penetrates through a bearing hole in the handle to be fixed, the upper end of the rope skipping handle is clamped and adjusted by a screw, and the bearing is driven to rotate by throwing the rope. The rope skipping device has the advantages that the rotating direction is consistent with the rope throwing direction, the rope skipping speed is high and smooth, the rope is not twisted, and the length of the rope can be freely adjusted according to the height and the exercise habit; however, the head is not beautiful, the bearings are assembled in the handle, the single bearings are separately connected with the middle shaft head, the stability is slightly problematic, the head is easy to fall off and is easy to shake or tilt under the influence of the throwing force of the skipping rope. The rope skipping handle is internally provided with double bearings, a universal head middle shaft element penetrates through a bearing hole in the handle, an internal screw is fixed, and the length of a rope is adjusted and the rope is prevented from slipping out through a hand-twisting screw on the rope outside the rope skipping handle. The universal head has the advantages that the appearance of the head is discussed, the rotating direction is more, the built-in double bearings are stable, and the problem of shaking of a shaft part in the universal head is well avoided; however, the appearance of the center shaft of the universal head attracts the eyeball, the rotation angle is larger, the rope skipping speed and the rope skipping smoothness cannot be effectively improved after rope threading, and the rope skipping is influenced by the screw buckle sometimes, so that the rope skipping is blocked. In addition, the two skipping rope handles are assembled by the bearing and the middle shaft in a split mode, and stability is not ideal.
