Detailed Description

To make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

The disclosed embodiment provides a cable rotating device, and as shown in fig. 1, the cable rotating device includes a support frame 1, a rotating frame 2 and an elastic member 3.

The support frame 1 comprises a support 11 and a cable supporting cylinder 12, wherein the cable supporting cylinder 12 is fixed on the support 11.

The rotating frame 2 is rotatably connected to the support 11 and sleeved outside the cable supporting cylinder 12, a rotating shaft of the rotating frame 2 is coaxial with the cable supporting cylinder 12, and an annular accommodating cavity 4 is formed between the rotating frame 2 and the outer side wall of the cable supporting cylinder 12.

Fig. 2 is a front view of a cable rotating apparatus provided in an embodiment of the present disclosure, and in conjunction with fig. 2, an elastic member 3 is wound in an annular receiving cavity 4, and a first end of the elastic member 3 is connected to an outer side wall of a cable supporting cylinder 12, a second end of the elastic member 3 is connected to a rotating frame 2, and the elastic member 3 has a cable installation cavity extending along its length inside.

When the cable rotating device provided by the embodiment of the disclosure realizes rotation of two ends of a cable, the cable rotating device comprises the support frame 1, the rotating frame 2 and the elastic part 3, so that the support 11 of the support frame 1 can support the cable support cylinder 12 and the rotating frame 2. Meanwhile, because the rotating frame 2 is rotatably connected to the supporting frame 1, the rotating frame 2 can rotate relative to the support 11 and the cable supporting cylinder 12 under the action of external force.

Furthermore, since the annular receiving cavity 4 is formed between the rotating frame 2 and the outer side wall of the cable supporting cylinder 12, the elastic member 3 is wound in the annular receiving cavity 4 in a bending manner, and the cable is installed inside the elastic member 3, a certain radial restoring force is generated when the elastic member 3 is wound in the annular receiving cavity 4 in a bending manner, and the elastic member 3 and the cable 100 inside the elastic member 3 tend to expand outward due to the radial restoring force. That is, when the cable 100 is initially installed inside the elastic member 3, the elastic member 3 and the cable 100 are restrained inside the turret 2 by the obstruction of the turret 2.

If the rotating frame 2 is rotated by an external force, and the external force drives the rotating frame 2 to rotate, the external force overcomes the radial restoring force generated by the elastic member 3, and the elastic member 3 and the cable 100 gradually approach the inner side of the annular accommodating cavity 4 (i.e. towards the cable supporting cylinder 12) and are wound on the outer wall of the cable supporting cylinder 12. Since the outer diameter of the cable support cylinder 12 is smaller than the inner diameter of the outer wall of the rotating frame 2, the number of bending turns of the cable 100 can be changed under the condition that the length of the cable 100 is not changed through the rotating frame 2, and finally, the relative rotation of the two ends connected with the cable 100 is realized. If the external force is removed, the cable 100 is restored to the initial state by the radial restoring force of the elastic member 3.

The cable rotating device provided by the embodiment of the disclosure has the advantages that the structure is simple, the use is convenient, the relative rotation of the two ends of the cable can be realized through the rotating frame 2, in addition, the cable 100 in the cable rotating device is a complete cable, the middle part of the cable is not provided with a joint, and the two ends of the cable 100 can be sealed through the watertight joint with mature technology, so the reliable watertight performance of the cable in the rotating process can be realized.
