Description

Bending-resistant cable

Technical Field

The utility model relates to the technical field of cables, in particular to a bending-resistant cable.

Background

The cable is used for power transmission and signal transmission widely used in various fields, and the cable on the market at present has poor rebound ability due to poor elasticity of the cable, so that the tension of the inner core and the outer core is unequal easily due to frequent bending operation or long-term continuous bending time, the cable core in the cable is twisted and shifted, even a fracture phenomenon is generated, and the bent part cannot be buffered, so that the use effect of the cable is affected.

Disclosure of Invention

The utility model aims to solve the defects in the prior art and provides a bending-resistant cable.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:

the utility model provides a cable of nai buckling, includes the inner liner, run through between the both ends of inner liner and be equipped with a plurality of buffer holes, peg graft in the inner liner and have had the cable core, the lag has been cup jointed in the outside of inner liner, is equipped with interior cavity between lag and the inner liner, the outer wall of inner liner has cup jointed the spring housing, and the spring housing sets up in the cavity, be equipped with a plurality of spacer rings between inner liner and the lag.

Further, the outer wall of the protective sleeve is fixedly connected with a plurality of raised strips.

Furthermore, a plurality of steel wires are inserted into the wall thickness of the protective sleeve.

Further, the buffer holes are of arc-shaped structures.

Further, a plurality of the buffer holes are distributed around the cable core annular array.

The beneficial effects of the utility model are as follows:

1. the arrangement of the spring sleeve in the inner cavity between the inner bushing and the protective sleeve enables the cable to have good elasticity, so that the rebound resilience performance of the cable is good, and the cable is prevented from being broken.

2. Impact force of the bending part of the cable is relieved through the buffer hole, so that the inner cable core can be protected from being damaged.

3. The cable can be better elastic through the cooperation setting of sand grip and steel wire to promote the bending resistance performance of cable.

In the figure: 1. an inner liner; 2. buffering holes; 3. a cable core; 4. a protective sleeve; 5. an inner cavity; 6. a spring sleeve; 7. a convex strip; 8. a steel wire; 9. and a spacer ring.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Referring to fig. 1-3, a bending-resistant cable comprises an inner bushing 1, a plurality of buffer holes 2 are penetrated and arranged between two ends of the inner bushing 1, impact force of bending parts of the cable is slowed down through the buffer holes 2 so as not to damage a cable core 3, the cable core 3 is inserted into the inner bushing 1, a protective sleeve 4 is sleeved on the outer side of the inner bushing 1, an inner cavity 5 is arranged between the protective sleeve 4 and the inner bushing 1, a spring sleeve 6 is sleeved on the outer wall of the inner bushing 1, the spring sleeve 6 is arranged in the inner cavity 5, the cable has good elasticity through the design that the spring sleeve 6 is arranged in the inner cavity 5 between the inner bushing 1 and the protective sleeve 4, a plurality of spacing rings 9 are arranged between the inner bushing 1 and the protective sleeve 4, and the inner bushing 1 and the protective sleeve 4 are convenient to connect through the spacing rings 9.

The outer wall integrated into one piece of lag 4 has a plurality of sand grip 7, has pegged graft a plurality of steel wires 8 in the wall thickness of lag 4, makes the cable have better elasticity through sand grip 7 and steel wire 8 to promote the resistant bending property of cable, buffer hole 2 is the arc structure, and a plurality of buffer holes 2 are distributed around cable core 3 annular array, so that slow down the impact force of buckling of cable better.

Working principle: when the cable bending device is used, firstly, the impact force of the bending part of the cable is slowed down through the buffer holes 2 so as not to damage the cable core 3, then, the cable has good elasticity through the design that the spring sleeve 6 is arranged in the inner cavity 5 between the inner bushing 1 and the protective sleeve 4, so that the cable has good rebound resilience performance, and then, the cable has better elasticity through the raised strips 7 and the steel wires 8, so that the bending resistance performance of the cable is improved.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
