Description

Technical Field

[0001] The utility model relates to the field of electric wires, in particular to an electric wire winding device for electric wires which are wear-resistant, oil-proof and have good shielding performance. Background Art

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables, which can be defined as: a collection of the following parts; one or more insulating cores, and their respective coatings, total protective layers and outer sheaths. Cables may also have additional uninsulated conductors.

[0003] However, the wires currently on the market do not have a structure for rolling up the wires, requiring users to lift the wire roll with great effort, which greatly increases the user's work intensity and reduces the user's work efficiency. In addition, the user is required to pull the wires additionally, which greatly increases the user's work steps and increases the user's work difficulty.

[0004] The Chinese utility model patent application number 202020345594.0 proposes a wire winding device for wires with good shielding performance and wear-resistant and oil-proof properties, but there are still some shortcomings:

[0005] 1. Because it uses compression springs and vertical structures for support, and the weight of the wire itself is large, the pressure on the upper vertical compression spring is greater than that on the lateral compression spring and greater than that on the lower vertical compression spring, causing the coil structure to deform;

[0006] Second, it adopts a vertical structure with a high center of gravity, which will lead to the overall instability. If the front and rear dimensions are designed to be larger, the overall volume will also be larger.

[0007] 3. The edge of the curved plate is not provided with a limiting structure, which will cause the wires to be wound in a disorderly manner;

[0008] Fourth, it does not have a locking structure for the wire ends, which may cause the wires to spread out when not in use, and is not convenient for quick secondary use;

[0009] 5. There is no active rotation structure at the drum, which means that the drum still needs to be rotated manually when winding the line, which is still laborious;

[0010] 6. Only feet are provided on the lower side of the bottom plate, and no labor-saving structure is provided, so it is very laborious to drag the bottom plate by the handle.

[0011] Based on this, the utility model proposes a new wear-resistant and oil-proof electric wire with good shielding performance to solve the above problems. Utility Model Content

[0012] In order to overcome the defects in the above-mentioned prior art, the utility model provides a wire winding device for electric wires with wear-resistant, oil-proof and good shielding performance. By arranging friction blocks and bolts, the base plate can be stably placed and easy to move; by arranging a wire locking rod, the wire end can be quickly locked and unlocked; the use of a flat roller lowers the center of gravity, enhances stability, and also allows the wire to be neatly rolled up.
