Detailed description of the invention
Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but this practicality is new
Type is not limited to listed embodiment.
As shown in Figure 1 to Figure 3, the thermal contraction casing tube 100 of the present embodiment includes metal level 1, thermoplastic layer 2 and fireprotection layer 3, institute
Stating thermoplastic layer 2 and be positioned at metal level 1 outer surface, described fireprotection layer 3 is positioned at thermoplastic layer 2 outer surface, i.e. thermoplastic layer 2 and is positioned at metal level 1
And between fireprotection layer 3.Can effectively prevent thermal contraction casing tube catching fire by arranging fireprotection layer, promote its safety.Described anti-
The thickness of fire bed 3 is less than the thickness of thermoplastic layer 2, thus avoids the thickness of thermal contraction casing tube blocked up, affects contractility.Described gold
Genus layer 1 is around forming hollow bulb 10, and described metal level 1 end is provided with conductor wire (not shown), connects ground by conductor wire
Face, can discharge the electrostatic in metal level, so that metal level produces shielding action.Heat shrinking sleeve end surfaces is provided with male and fomale(M&F) 4,
Male and fomale(M&F) 4 can enable workman night etc. cannot visually in the case of use thermal contraction casing tube time determine spout part by touch
Position；Meanwhile, when needing two thermal contraction casing tubes adjacent, using the teaching of the invention it is possible to provide good contact surface.Described fireprotection layer 3 is by glass fibre system
Becoming, glass fibre heatproof is high, does not fires, anti-corruption, heat insulation, therefore, it is possible to play fireproofing function, can protect cable anticorrosive simultaneously,
Extend the service life of thermal contraction casing tube.The thermal contraction casing tube of technique scheme can be the most fire-retardant, promotes safety and prolongs
Long life；Meanwhile, it is capable to be easy in various varying environments use thermal contraction casing tube.
As shown in Figure 1 to Figure 3, further, described metal level is formed by metal braid, and described thermoplastic layer is by polyolefin
Material and rubber combined make, so that thermoplastic layer can have certain elasticity, by thermal contraction casing tube is heated, thermoplastic layer
Shrink with metal level simultaneously, provide effective electromagnetic shielding for cable.Described hollow bulb 10 is provided with limiting section 5, limiting section 5 edge
Hollow bulb axis direction interval is arranged, and limiting section 5 bonds with metal level.Thermal contraction casing tube can be made after shrinking by limiting section 5
Can effectively contact with body surface, it is to avoid radially slide or shrink.Described limiting section 5 includes many fins 51, between fin 51
Every setting, fin 51 can strengthen the intensity of thermal contraction casing tube.The outside of the thermal contraction casing tube of the present embodiment is provided with fluorescent belt 6, glimmering
Light belt can arrange different colors according to different product types, thus when carrying on construction work at night, it is possible to it is easy to find heat shrinking sleeve
Pipe, is conducive to improving efficiency of construction.
The thermal contraction casing tube of the present embodiment can effectively promote fire resistance, promotes its safety and service life；Meanwhile,
Workman can be made to could be used that under the rough sledding such as night and to accurately identify thermal contraction casing tube, be effectively improved efficiency of construction；This
Outward, after thermal contraction casing tube shrinks, it is possible to prevent it from moving radially, it is conducive to wrap the parts such as cable.
It is pointed out that above-mentioned preferred embodiment only illustrates technology of the present utility model design and feature, its purpose
It is to allow person skilled in the art will appreciate that content of the present utility model and to implement according to this, this reality can not be limited with this
With novel protection domain.All equivalence changes made according to this utility model spirit or modification, all should contain in this reality
Within novel protection domain.
