SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is to solve the technical deficiencies, and provide an anti-distortion flexible power cable, which adopts the structure that the outer surface of the surface layer sheath is uniformly provided with circular protrusions, so that the circular protrusions are utilized to contact with the ground, thereby reducing the contact area between the surface layer sheath of the cable and the ground, reducing the loss of the surface layer sheath of the cable, prolonging the service life of the cable, and solving the problem that the service life of the existing cable is lower due to frequent dragging when in use; adopt cable sheath, flexible sheath and top layer sheath all are the structure of X form to effectively guarantee that inside cable core and outside top layer sheath can not take place the condition of distortion dislocation, solved traditional cable and frequently appeared the cracked condition of inside cable core dislocation after dragging easily.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: comprises a cable sheath; a central position in the cable sheath is provided with a traction through hole; a steel strand is arranged in the traction through hole; the steel strand and the traction through hole are in interference fit; the periphery inside the cable sheath is respectively provided with a wire core through hole; a cable core is arranged in the core through hole; an insulating sheath covers the outside of the cable core; the inner surface of the insulating sheath is in interference fit with the cable core; the outer surface of the insulating sheath is in interference fit with the through hole of the wire core; a first through hole is formed in the middle line position between the wire core through holes; second through holes are symmetrically formed in two sides of the first through hole; a surface layer sheath is arranged outside the cable sheath; the outer surface of the surface layer sheath is uniformly provided with circular bulges; the circular protrusions are arranged spirally.

Further optimizing the technical scheme, a flexible sheath is arranged between the cable sheath and the surface layer sheath; the flexible sheath is of a fluffy porous structure.

Further optimize this technical scheme, cable sheath and flexible sheath all are X form.

Compared with the prior art, the utility model has the advantages of it is following: 1. the structure that the circular protrusions are uniformly arranged on the outer surface of the surface layer sheath is adopted, so that the circular protrusions are in contact with the ground, the contact area between the surface layer sheath of the cable and the ground is reduced, the loss of the surface layer sheath of the cable is reduced, and the service life of the cable is prolonged; 2. adopt cable sheath, flexible sheath and top layer sheath all are the structure of X form to effectively guarantee that the condition of distortion dislocation can not take place for inside cable core and outside top layer sheath.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The specific implementation mode is as follows: shown in connection with fig. 1-2, includes a cable jacket 1; a central position in the cable sheath 1 is provided with a traction through hole 101; a steel strand 102 is arranged in the traction through hole 101; the steel strand 102 and the traction through hole 101 are in interference fit; the periphery of the inside of the cable sheath 1 is respectively provided with a wire core through hole 103; a cable core 104 is arranged in the core through hole 103; the cable core 104 is externally covered with an insulating sheath 105; the inner surface of the insulating sheath 105 is in interference fit with the cable core 104; the outer surface of the insulating sheath 105 is in interference fit with the wire core through hole 103; a first through hole 106 is arranged at the middle line position between the wire core through holes 103; second through holes 107 are symmetrically arranged on two sides of the first through hole 106; a surface layer sheath 2 is arranged outside the cable sheath 1; the outer surface of the surface layer sheath 2 is uniformly provided with circular bulges 201; the circular protrusions 201 are arranged in a spiral shape; a flexible sheath 3 is arranged between the cable sheath 1 and the surface layer sheath 2; the flexible sheath 3 is of a fluffy porous structure; the cable sheath 1 and the flexible sheath 3 are both X-shaped.
