As preferred technical scheme, every group cable comprises outer tegument, filling layer and inside heart yearn, and outer tegument all is the triangle-shaped structure setting, and the lateral surface of outer tegument all is the arc structure setting, and the heart yearn all sets up inside outer tegument, and the filling layer all sets up between heart yearn and outer tegument.

As the preferred technical scheme, the corners of both sides of the baffle are arranged in an arc structure.

As a preferred technical scheme, the outer side surface of each group of cables is abutted against the inner ring surface of the fixing ring.

In this embodiment, each group of cables is matched with the installation groove.

The utility model has the advantages that: the utility model discloses simple structure, the cable divide into several strands and install between the baffle, after the exterior tegillum of one of them heart yearn damages, only need to change this group's cable, need not to carry out whole cables, has avoided the waste of material, and can effectual increase fastness through the baffle, great reduction because of the damage that the external force extrusion caused, increased the security.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.

Fig. 1 is a schematic view of the overall structure of the present invention;

fig. 2 is a schematic view of the connection structure between the central shafts of the present invention.

Detailed Description

As shown in fig. 1 and fig. 2, a cable comprises more than one central shaft 8, more than one fixing ring 1 and a cable, wherein four baffles 2 are welded on the outer wall surface of the central shaft 8, the four baffles 2 are uniformly distributed in a diamond structure, a mounting groove with a triangular structure is formed between each baffle 2 and each baffle 2, the cable is divided into four groups, each group of cables is arranged in the mounting groove along the central shaft, inner threads are arranged on the end surfaces of the outer sides of the baffles 2, outer threads are arranged on the inner ring surfaces of the fixing rings 1, the fixing rings 1 are arranged outside the baffles 2 and are meshed and connected with the inner threads on the baffles 2 through the outer threads, each group of cables positioned between the baffles 2 is wrapped and fixed by the fixing rings 1, screw holes are arranged on the two end surfaces of the central shaft 8, a screw bolt 6 is connected in the screw holes in a threaded manner, a connecting lug 7 is welded on the end surface of, a steel wire rope 10 is connected between the adjacent connecting lugs 7.

In this embodiment, every group cable comprises outer tegument 5, filling layer 3 and inside heart yearn 4, and outer tegument 5 all is the triangle-shaped structure setting, and outer tegument 5's lateral surface all is the arc structure setting, and heart yearn 4 all sets up inside outer tegument 5, and filling layer 3 all sets up between heart yearn 4 and outer tegument 5.

In this embodiment, the angle of 2 both sides of baffle all is the arc structure setting, when crooked, has avoided the cable damage because of the angle is sharp and is caused.

In this embodiment, the lateral surface of every group cable offsets with the interior anchor ring of solid fixed ring 1, gu fixed ring can effectually compress tightly the outside of cable inwards, makes the cable compress tightly by solid fixed ring and is fixed in the mounting groove.

In this embodiment, each group cable and mounting groove between the phase-match, increased with the installation between the mounting groove coincide nature.

Every group cable distribution is installed in the mounting groove to all by fixed hoop internal pressure fastening fixed, after the tegument of one of them cable damaged, unscrew solid fixed ring and just can take out the cable of this damage, remaining and the use that can continue only need change a new cable, and compress tightly fixedly through solid fixed ring and just can continue to use, avoided the waste of material and the increase of cost.

Wherein, outside extrusion force can be used in on the baffle, can effectually offset the extrusion force through the baffle, has avoided pressure to act on the cable, has avoided the damage of cable, wherein, because connect through wire rope between the center pin to flexible between the center pin, simultaneously when one of them epaxial baffle of center damages the back, unscrews the double-screw bolt, just can take out the baffle and the center pin that damage, has made things convenient for and has changed it, need not whole change.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the creative work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
