Example one

Fig. 1 is a schematic structural view of a cable protection device according to an embodiment of the present invention.

Referring to fig. 1, a first embodiment of the present invention provides a cable protection device 1000 applied to a rotating device having a rotating post and a rotating device body 2000 disposed around the rotating post. The cable protection device 1000 includes a support portion 100 and a cable flexible transmission portion 300. The flexible cable transmission part 300 is disposed on the support part 100, a first end of the flexible cable transmission part 300 is fixedly disposed on the support part 100, a second end of the flexible cable transmission part 300 opposite to the first end is fixedly connected to the rotating device body 2000, and the flexible cable transmission part 300 has a passage penetrating through both ends of the flexible cable transmission part. The cable passes through the channel and the cable is slidable within the channel. The other end of the flexible cable transmission part 300 moves the cable 3000 on the support part 100 by the rotation of the rotation device body 2000. Because the one end of cable 3000 is fixed in on the flexible conveying part 300 of cable, consequently, the difficult emergence of cable drops, twines or other risks, and cable 3000 also can move certain angle on supporting part 100, guarantees the normal use of cable 3000.

Fig. 2 is a partial schematic view of a support according to an embodiment of the invention.

Wherein the support 100 includes a moving rail 110. Referring to fig. 2, the moving rail 110 is disposed around the rotating post, thereby providing a rail for the cable 3000 to move around the rotating post.

As an embodiment of the present invention, the moving rail 110 includes a base plate 111 disposed around the rotating post, and a guard rail 112 extended from an edge of a surface of the base plate 111, which carries the cable, in a direction away from the base plate 111.

Preferably, the bottom plate 111 is circular in shape. In order to fix the movement trace of the partial cable 3000 so that the cable 3000 can stably rotate by a larger angle, the base plate 111 includes a first rail 113 and a second rail 114 as an embodiment of the present invention. One end of the first rail 113 is connected to one end of the second rail 114, and the other end of the second rail 114 is connected to the other end of the second rail 114, that is, the first rail 113 is connected to the second rail 114 end to end. The width of the first track 113 is greater than the width of the second track 114. Preferably, the width of the first rail 113 is at least more than twice the width of the cable flexible transfer part 300, so as to provide a sufficient moving space for the cable flexible transfer part 300. Preferably, the width of the second rail 114 is the same as the width of the cable flexible transmission part 300 or slightly larger than the width of the cable flexible transmission part 300, so that the passage of the cable flexible transmission part 300 can be satisfied while limiting the moving trace of the cable passing through the second rail 114.

Further, the first end of the flexible cable transmission part 300 is fixedly disposed at the end of the first rail 113 far from the side of the rotating column, and is close to the outer guard rail 112, specifically, the starting point of the second rail 114 is disposed at the connection point of the flexible cable transmission part 300 and the first rail 113, because when the flexible cable transmission part (300) moves on the first rail, if the moving end of the flexible cable transmission part 300 does not exceed the fixed end, the bent portion of the flexible cable transmission part 300 on the moving rail will collide with each other, and form a constraint on the flexible cable transmission part 300, thereby ensuring that the side of the flexible cable transmission part 300 facing the rotating column is always attached to the guard rail 112. When the moving end of the flexible cable transmission part 300 exceeds the fixed end, the exceeding part is not restricted and cannot be always attached to the guard rail 112, so that the second rail 114 needs to be arranged, the width of the second rail 114 is small, a limiting effect can be achieved on the flexible cable transmission part 300, and the length of the second rail 114 is adaptively arranged according to the maximum length of the moving end of the flexible cable transmission part 300 exceeding the fixed end.

Further, the end of the second rail 114 is provided with a guide piece. One end of the guide piece is fixedly connected with a guard rail 112 on the second track 114 far away from the rotating upright post.
