Description
Technical field
The utility model relates to a kind of cable sheath, in particular to a kind of cable sheath with flame retarding function.
Background technique
The effect of cable sheath is: liner layer between armor and sheath, effect be prevent sheath by
To corrosion, and prevent sheath in cable bend by armouring damage layer, for armor outside liner layer, effect is reduction machine
Influence of the tool power to cable makes the mechanical force being applied on cable by armor to bear, and serving is outside armor, effect
It is to prevent armor from suffering erosion.So the effect of protective coverings of cable is to protect sheath from external world's influence and mechanical damage.
The flame retardant effect of existing cable sheath is poor, once fire, which occurs, substantially to blow influence work by cable.Cause
This, it is proposed that a kind of cable sheath with flame retarding function.
Utility model content
The main purpose of the utility model is to provide a kind of cable sheaths with flame retarding function, can effectively solve
The problems in background technique.
To achieve the above object, the technical solution that the utility model is taken are as follows:
A kind of cable sheath with flame retarding function, including inner protective tube, the inner protective tube outer wall are fixedly connected with multiple groups
The support end being equally spaced, the one end of support end far from inner protective tube described in multiple groups are fixedly connected with intermediate casing inner wall, and adjacent two
It is filled with flame retardant rubber between the group support end, the intermediate casing outer wall is fixedly connected with tinfoil paper layer.
Further, the inner protective tube inner-wall spraying has fireproof coating.
Further, the flame retardant rubber is between intermediate casing and inner protective tube.
Further, the tinfoil paper layer outer wall is fixedly connected with fire protection flame retarding PP outer tube.
Compared with prior art, the utility model has the following beneficial effects:
1. the cable sheath with flame retarding function of the utility model, by being fixedly connected with multiple groups in inner protective tube outer wall
The support end being equally spaced, the one end of multiple groups support end far from inner protective tube are fixedly connected with intermediate casing inner wall, two adjacent groups branch
It supports and is filled with flame retardant rubber between end, can not only carry out fire-retardant but also anti-extrusion can be carried out, improve safety.
2. the cable sheath with flame retarding function of the utility model, due to thering is fire prevention to apply in inner protective tube inner-wall spraying
Material, intermediate casing outer wall are fixedly connected with tinfoil paper layer, further increase the flame retardant effect of sheath, can also avoid external electromagnetism
Interference.
Detailed description of the invention
Fig. 1 is the overall structure diagram for the cable sheath that the utility model has flame retarding function.
In figure: 1, inner protective tube；2, flame retardant rubber；3, fire protection flame retarding PP housing；4, tinfoil paper layer；5, intermediate casing；6, it supports
End；7, fireproof coating.
Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figure 1, a kind of cable sheath with flame retarding function, including inner protective tube 1,1 outer wall of inner protective tube are solid
Surely it is connected with the support end 6 that multiple groups are equally spaced, the one end of support end 6 far from inner protective tube 1 described in multiple groups and 5 inner wall of intermediate casing
It is fixedly connected, flame retardant rubber 2 is filled between support end 6 described in two adjacent groups, 5 outer wall of intermediate casing is fixedly connected with tin
Layers of foil 4.
The support end 6 that multiple groups are equally spaced, multiple groups are fixedly connected in 1 outer wall of inner protective tube as shown in Figure 1 in the present embodiment
The one end of support end 6 far from inner protective tube 1 is fixedly connected with 5 inner wall of intermediate casing, filled with resistance between two adjacent groups support end 6
Rubber 2 is fired, can not only carry out fire-retardant but also anti-extrusion can be carried out, safety is improved, due to having fire prevention in 1 inner-wall spraying of inner protective tube
Coating, 5 outer wall of intermediate casing are fixedly connected with tinfoil paper layer 4, further increase the flame retardant effect of sheath.
Wherein, 1 inner-wall spraying of inner protective tube has fireproof coating 7.
As shown in Figure 1, carrying out fire protection flame retarding to cable convenient for final step in the present embodiment.
Wherein, the flame retardant rubber 2 is between intermediate casing 5 and inner protective tube 1.
As shown in Figure 1, can not only carry out fire-retardant but also anti-extrusion can be carried out in the present embodiment, safety is improved.
Wherein, 4 outer wall of tinfoil paper layer is fixedly connected with fire protection flame retarding PP outer tube 3.
As shown in Figure 1, being carried out in outermost layer fire-retardant in the present embodiment.
Working principle: it in use, fire protection flame retarding PP housing 3 carries out preliminary fire-retardant, is fixedly connected in 1 outer wall of inner protective tube more
The support end 6 that group is equally spaced, the one end of multiple groups support end 6 far from inner protective tube 1 is fixedly connected with 5 inner wall of intermediate casing, adjacent
It is filled with flame retardant rubber 2 between two groups of support ends 6, can not only carry out fire-retardant but also anti-extrusion can be carried out, improves safety, by
In having fireproof coating in 1 inner-wall spraying of inner protective tube, 5 outer wall of intermediate casing is fixedly connected with tinfoil paper layer 4, further increases sheath
Flame retardant effect.
