[0013] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0014] Embodiment 1:

[0015] like Figure 1 , Figure 2 As shown, the utility model discloses a cable wound into a capstan, comprising a connecting disk 1, the center of the connecting disk 1 is fixedly connected to the output shaft of a power mechanism, and the power mechanism drives the connecting disk 1 to rotate; an inwardly concave cylindrical cavity 9 is arranged inwardly at one axial end of the connecting disk 1, and a plurality of through holes 10 along the radial direction are arranged in a circumferentially spaced array of the connecting disk 1, and the cross-section of the through hole 10 is non-circular, and a support rod 2 is arranged in the through hole 10, and the cross-section of the support rod 2 is consistent with the cross-section of the through hole 10, one end of the support rod 2 is located outside the connecting disk 1, and the other end of the support rod 2 extends into the cavity 9, and an arc-shaped support plate 3 is arranged at the end of the support rod 2 outside the connecting disk 1, and a telescopic mechanism is arranged in the cavity 9, and the telescopic mechanism drives all the support rods 2 to move outward or inward synchronously to change the diameter of the circle where the arc-shaped support plate 3 is located.

[0016] The power mechanism refers to the power mechanism on the existing winding equipment, generally refers to the combination of the motor and the reduction box, and the output shaft in this embodiment refers to the output shaft of the reduction box. The output shaft is fixedly connected to the connecting disk 1, and the central axis of the output shaft coincides with the central axis of the connecting disk 1, so that the output shaft can rotate with the connecting disk 1. The number of support rods 2 can be selected according to actual needs, but not less than 2. The arc-shaped support plates 3 on the support rods 2 can be butt-jointed end to end in the retracted state, and there is a gap between the arc-shaped support plates 3 when in the open state. The telescopic mechanism pushes the support rod 2 outward so that the arc-shaped support plate 3 is on the circumference of the larger diameter, and then the cable is wound into a twist. After the winding is completed, there is tension between the cable and the arc-shaped support plate 3. In order to facilitate the removal, the telescopic mechanism drives the support rod 2 to retract, so that the arc-shaped support plate 3 is on the circumference of the smaller diameter, and the arc-shaped support plate 3 is separated from the twisted cable, which is convenient for removal. The cross-section of the through hole 10 is non-circular, and may be rectangular, elliptical, etc., or a rectangular positioning groove may be provided inside the circular through hole 10, and a positioning protrusion may be provided on the circular rod body of the support rod 2, the purpose of which is to prevent the support rod 2 from rotating during the movement in the through hole 10, so that the arc-shaped support plate 3 will not have an angular deviation, so as to ensure the normal operation of the equipment and more reliable winding.

[0017] The structure of the telescopic mechanism is as follows: a rotating shaft 4 is arranged at the center of the connecting disk 1 in the cavity 9, and the rotating shaft 4 is rotatably connected to the connecting disk 1. A supporting ring 11 is arranged on the rotating shaft 4 in the cavity 9, and an arc-shaped protruding structure 12 is arranged on the outside of the supporting ring 11. The arc-shaped protruding structure 12 corresponds to the supporting rod 2 one by one, and the end of the supporting rod 2 abuts against the arc-shaped protruding structure 12. When the rotating shaft 4 drives the supporting ring 11 to rotate, the supporting rod 2 abuts against different parts of the arc-shaped protruding structure 12. A round cover 6 is arranged on the rotating shaft 4, and positioning holes 7 are arranged on the round cover 6 and the connecting disk 1. When the positioning hole 7 on the round cover 6 corresponds to the positioning hole 7 on the connecting disk 1, the support rod 2 abuts against the outermost side of the arc-shaped protruding structure 12, and a positioning pin 8 is inserted in the positioning hole 7.

[0018] A handle 5 can be provided at the end of the rotating shaft 4 for rotating the rotating shaft 4. When the rotating shaft 4 rotates, the support ring 11 on the rotating shaft 4 also rotates with the rotating shaft 4, so the arc-shaped protrusion structure 12 also rotates with the rotating shaft 4. Each support rod 2 corresponds to an arc-shaped protrusion structure 12, and the end of the support rod 2 abuts against the arc-shaped protrusion structure 12. When the support rod 2 is in a retracted state, the end of the support rod 2 abuts against the part of the arc-shaped protrusion structure 12 that is closer to the rotating shaft 4, and when the support rod 2 needs to be unfolded, the rotating shaft 4 rotates, and the contact part between the support rod 2 and the arc-shaped protrusion structure 12 gradually shifts to a part farther from the center of the rotating shaft 4, so the support rod 2 moves outward. All the arc-shaped protrusion structures 12 are arranged in an annular array on the circumferential outer wall of the support ring 11, so when the rotating shaft 4 rotates, the effect on all the support rods 2 is the same, and all the support rods 2 move synchronously with the same movement amplitude.

[0019] A retaining ring 13 is provided on the support rod 2 in the cavity 9, and a compression spring 14 is sleeved on the support rod 2 between the retaining ring 13 and the inner wall of the cavity 9. In the design of the retaining ring 13 and the compression spring 14 on the support rod 2, in a natural state, the support rod 2 is subjected to the outward movement force provided by the compression spring 14, so when the rotating shaft 4 rotates to return the support rod 2 to the retracted state, all the support rods 2 will always be in contact with the arc-shaped protruding structure 12, and can be automatically retracted, which is more convenient to use.

[0020] A support portion 15 is provided at the end of the support rod 2 inside the cavity 9. The support portion 15 is a hemispherical structure, and the diameter of the support portion 15 is smaller than the size of the support rod 2. Under normal circumstances, the semicircle of the support portion 15 is located within the end surface range of the support rod 2. The size of the support portion 15 is small, and there is enough space when it cooperates with the arc-shaped convex structure 12, so as to avoid interference with other components when the support portion 15 moves on the arc-shaped convex structure 12, thereby improving the stability of the equipment operation. At the same time, the lower part of the support portion 15 is an arc surface, which contacts the arc surface of the arc-shaped convex structure 12, and the movement process is also smoother.

[0021] The support rod 2 and the support part 15 are connected by a conical surface. The support rod 2 and the support part 15 are connected by a conical surface, the size is gradually reduced, and the connection part is also firm and stable.

[0022] The arc-shaped protrusion structure 12 has an arc length of 90°, and one of the straight edges of the arc-shaped protrusion structure 12 is arranged along the radial direction. The arc surface structure with an arc length of 90°, that is, the arc surface of a quarter of a cylinder, can increase the pushing distance of the support rod 2 in the smallest possible range to ensure reliability and stability. It can also increase the number of support rods 2 as much as possible within a fixed size range to improve the support performance.
