Detailed Description
The invention will be further described with reference to the following embodiments in order to make the technical means, the creation features, the achievement of the objects and the effects of the invention easy to understand.
Example 1
As shown in fig. 1, the high-speed paying-off function device for the electric wires and the cables comprises a fixed structure, a rotating structure and a guiding structure. The rotating structure is arranged at the center of the fixed structure, the rotating structure can rotate by taking the rotating structure as an axle center, the middle section of the guiding structure is fixed on the rotating structure, and the guiding structure can rotate along with the rotating structure.
The fixing structure is a fixing frame 1, and the fixing frame 1 is fixed at a hole on the side surface of the cable reel and is close to the side surface of the cable reel. The fixing frame 1 is a cross-shaped fixing frame, and the length of the fixing frame 1 can be adjusted. The length of the four end points of the cross-shaped fixing frame can be adjusted and fixed.
The rotating structure is arranged at the center of the fixing frame 1, the rotating structure is a rotating shaft 2, the rotating shaft 2 can rotate by taking the center of the rotating structure as the axis, and the rotating structure is parallel to the plane of the side face of the cable drum. The middle part of the rotating shaft 2 is provided with a mounting hole for accommodating the guiding mechanism.
The guide structure is a guide rod 3, the guide rod 3 is in the shape of a shaft, one end of the shaft is bent towards one direction, the angle of the bent part is 135-145 degrees, and 140 degrees are adopted in the embodiment.
