Utility model content
In order to solve the technical problem existed in background technology, the utility model proposes a kind of anti-extrusion cable of resistance to pulling force, not fragile when being subject to larger extruding force.
The anti-extrusion cable of resistance to pulling force of the one that the utility model proposes, is characterized in that, comprises cable core, lapping layer, the first restrictive coating;
Cable core comprises four wires, the first bolster, four the second bolsters, wire comprises the conductor being positioned at middle part, the insulating barrier being coated on conductor outside, is coated on the screen outside insulating barrier and is coated on the second restrictive coating outside screen, the section radius of wire is R, the cross section of the first bolster is in square, the square length of side is L, L>R, square adjacent both sides arc transition;
First bolster is positioned in the middle part of cable core, and four wires are parallel longitudinal, and every root wire is against place, the square limit plane of the first bolster, the second bolster between adjacent two wires away from the first bolster side;
Lapping layer is wrapped outside at cable core, and the first restrictive coating is coated on lapping layer outside.
Preferably, there is in the first bolster the first cavity axially run through along cable.
Preferably, the second bolster is surrounded by first surface and the second curved surface, and first surface is against adjacent two wires, and the second curved surface is positioned at circumferentially same, has the second cavity axially run through along cable in the second bolster.
Preferably, the first bolster and the second bolster all adopt elastic insulated elastomeric material to make.
Preferably, lapping layer adopts that polyester belt is wrapped forms.
Preferably, insulating barrier adopts polythene material to make.
Preferably, screen adopts that copper wire is wrapped forms.
Preferably, the first restrictive coating and the second restrictive coating all adopt wearing composite material to make.
The anti-extrusion cable of resistance to pulling force of the one that the utility model proposes, first bolster cross section is in square, wire is respectively against the plane at place, square each limit, second bolster between adjacent two wires away from the first bolster side, lapping layer is coated on the cable core outside of wire, the first bolster, the second bolster composition, and the first restrictive coating is coated on lapping layer outside.By above-mentioned optimal design, the first bolster and the second bolster buffering receive extruding force to cable and cushion, and add the anti-extrusion ability of cable; In first bolster and the second bolster, cavity is set, the buffer distance of bolster is increased, further increases the buffering effect of bolster; Meanwhile, the first bolster and the second bolster longitudinal, can the part pulling force that is subject to of load-bearing cable, the resistance to tension of cable increases.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of anti-extrusion cable of resistance to pulling force that the utility model proposes.
Embodiment
As shown in Figure 1, Fig. 1 is the structural representation of a kind of anti-extrusion cable of resistance to pulling force that the utility model proposes.
With reference to Fig. 1, the utility model proposes a kind of anti-extrusion cable of resistance to pulling force, comprise cable core, lapping layer 4, first restrictive coating 5.
Cable core comprises four wires 1, first bolster, 2, four the second bolsters 3, wire comprises the conductor 11 being positioned at middle part, the insulating barrier 12 being coated on conductor outside, is coated on the screen 13 outside insulating barrier 12 and is coated on the second restrictive coating 14 outside screen 13, insulating barrier 12 adopts polythene material to make, screen 13 adopts that copper wire is wrapped to be formed, the section radius of wire 1 is R, the cross section of the first bolster 2 is in square, the square length of side is L, L>R, square adjacent both sides arc transition.
First bolster 2 is positioned in the middle part of cable core, there is in first bolster 2 the first cavity 21 axially run through along cable, four wires 1 are parallel longitudinal, and every root wire 1 is against place, the square limit plane of the first bolster 2, second bolster 3 between adjacent two wires 1 away from the first bolster 2 side, second bolster 3 is surrounded by first surface and the second curved surface, first surface is against adjacent two wires 1, second curved surface is positioned at circumferentially same, there is in second bolster 3 the second cavity 31 axially run through along cable, first bolster 2 and the second bolster 3 all adopt elastic insulated elastomeric material to make.
Lapping layer 4 is wrapped outside at cable core, and lapping layer 4 adopts that polyester belt is wrapped to be formed, and it is outside that the first restrictive coating 5 is coated on lapping layer 4, and the first restrictive coating 5 and the second restrictive coating 14 all adopt wearing composite material to make.
During concrete use, when Exterior cable is squeezed, extruding force passes to cable core 1 after the second bolster 3 cushions, and the extruding force that now cable core 1 is subject to will reduce, after the extruding force that cable core 1 is subject to, extruding force is delivered to the first bolster 2 and carries out extruding force buffering, through two-stage buffering after, the damage of extruding force to cable weakens greatly, cable be subject to vertically pulling force time, first bolster 2 and the second bolster 3 can carry a part of pulling force, can strengthen the overall resistance to tension of cable.
The anti-extrusion cable of resistance to pulling force of one of the present utility model, first bolster 2 cross section is in square, wire 1 is respectively against the plane at place, square each limit, second bolster 3 between adjacent two wires away from the first bolster 2 side, lapping layer 4 is coated on the cable core outside of wire, the first bolster 2, second bolster 3 composition, and it is outside that the first restrictive coating 5 is coated on lapping layer 4.By above-mentioned optimal design, first bolster 2 and the second bolster 3 cushion and cushion the cable power of being squeezed, add the anti-extrusion ability of cable, in first bolster 2 and the second bolster 3, cavity is set, the buffer distance of bolster is increased, further increases the buffering effect of bolster, simultaneously, first bolster 2 and the second bolster 3 longitudinal, can the part pulling force that is subject to of load-bearing cable, the resistance to tension of cable increases.
The above; be only the utility model preferably embodiment; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, all should be encompassed within protection range of the present utility model.
