Abstract

The utility model discloses an anti outdoor cable that extrudees, including the cable body, the cross-section of cable body is the ellipse, and cable body outside-in is buffer layer and flexible packing layer, and the upper portion cross-section interval of buffer layer is greater than lower part cross-section interval, and flexible packing layer outside-in includes flexible packing ball and elastic fiber, and elastic fiber's middle part position is equipped with elastic support and cable core, and the cable core is held respectively at elastic support's both ends, the utility model has the advantages of reasonable design, has strengthened the anti extrusion ability of cable.

Description

Anti-extrusion outdoor cable

Technical Field

The utility model belongs to the technical field of the cable, concretely relates to outdoor cable of anti extrusion.

Background

With the development of society, the performance requirements on cables are higher and higher, and especially in some environments with higher outdoor pressure (for example, the cables arranged outdoors need to be frequently rolled by large-scale vehicles such as cars or trucks), the wires inside the cables can be mutually extruded, so that cable cores are deformed or even broken, and the smoothness of electric power and communication cannot be ensured; in addition, the cross-section of current cable is mostly circular, and this kind of appearance is unfavorable for the smooth rolling of small-size bicycle such as tricycle or bicycle that travel and has crossed the cable, may lead to the turnover of small-size bicycle even, causes personnel's injury.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model provides an anti outdoor cable of using of extrusion to solve the problem of above-mentioned technique.

The utility model discloses a realize through following technical scheme: the utility model provides an anti extrusion outdoor cable, includes the cable body, the cross-section of cable body is oval, cable body outside-in is buffer layer and flexible packing layer, the upper portion cross-section interval of buffer layer is greater than lower part cross-section interval, flexible packing layer outside-in includes flexible packing ball and elastic fiber, elastic fiber's middle part position is equipped with elastic support and cable core, the centre gripping respectively at elastic support's both ends the cable core.

Furthermore, a plurality of damping springs are arranged in the damping layer at uniform intervals.

Compared with the prior art, the beneficial effects of the utility model are that: when the cable body of the utility model is acted by external force, most of stress can be discharged by the deformation of the damping springs arranged in the damping layer at uniform intervals, and the anti-extrusion strength is high; the stress of the flexible filler balls and the elastic fibers in the flexible filler layer is removed, so that the anti-extrusion strength of the cable is enhanced; the design of the oval cross section of the cable body can enable stress generated when the large-scale vehicle rolls the cable body to be transferred to the flexible filler balls, the flexible filler balls push the cable core clamped by the elastic support to the other side of the elastic fiber, and meanwhile the design of the oval cross section is beneficial to smooth rolling of the small bicycle.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is a first state diagram of the present invention;

fig. 3 is a state diagram of the present invention.

In the drawings: 1. a cable body; 2. a shock-absorbing layer; 3. a flexible filler layer; 31. a flexible filler ball; 32. an elastic fiber; 4. an elastic support; 5. a cable core; 6. a shock absorbing spring.

Detailed Description

The anti-extrusion outdoor cable comprises a cable body 1, wherein the cross section of the cable body 1 is oval, the cable body 1 is provided with a damping layer 2 and a flexible packing layer 3 from outside to inside, most of stress can be removed by the deformation of damping springs 6 uniformly arranged in the damping layer 2 at intervals, the anti-extrusion strength is high, the interval of the upper section of the damping layer 2 is larger than that of the lower section, the anti-extrusion capability of the upper section is improved, the flexible packing layer 3 comprises flexible filler balls 31 and elastic fibers 32 from outside to inside, the middle positions of the elastic fibers 32 are provided with elastic supports 4 and cable cores 5, two ends of each elastic support 4 respectively clamp the cable cores 5, the two cable cores 5 are ensured to move simultaneously, and the removal of part of stress of the flexible filler balls 31 and the elastic fibers 32 in the flexible packing layer 3 is also beneficial to enhancing the anti-extrusion strength of the cable;

as shown in fig. 2, when the wheel rolls on one side of the cable body 1, the stress generated is transmitted to the flexible filler balls 31, so that the flexible filler balls 31 deform and move, and the flexible filler balls 31 push the cable core 5 clamped by the elastic support 4 to the other side of the elastic fiber 32, so as to prevent the stress generated by rolling from directly acting on the cable core 5;

as shown in fig. 3, when the wheel rolls over the cable body 1 to the other side, one side of the originally rolled cable body 1 is restored to the original shape, and the stress generated at the other side of the cable body 1 is transmitted to the flexible filler balls 31, so that the flexible filler balls 31 deform and move, and the flexible filler balls 31 push the cable core 5 clamped by the elastic support 4 from the side shown in fig. 2 to the side of the elastic fiber 32 shown in fig. 3, so as to prevent the stress generated by rolling from directly acting on the cable core 5;

the cross section of the cable body 1 is oval, and the oval cross section design not only enlarges the moving space of the cable core 5 in the elastic fiber 32, but also is beneficial to smooth rolling of a small bicycle to pass through the cable.

In summary, the present invention is only a preferred embodiment, and is not intended to limit the scope of the present invention, and all equivalent changes and modifications of the shapes, structures, features and spirit described in the claims of the present invention should be included in the scope of the present invention.
