Stability is good, and rigidity and toughness also with higher, mechanical strength is good, and dielectric properties, environmental stress crack resistance are also preferable.
In actual use, existing communication tube bending when be easy to damage tube body, using the time it is long when, knee hold
It easily ruptures, and the hardness of tube body upon bending is inadequate, is easily broken off.
Utility model content
The purpose of this utility model is: a kind of Tensible flexible high density polyethylene (HDPE) communication tube is intended to provide, for solving
Is easy to damage tube body in bending caused by existing communication tube fault of construction, using the time it is long when, knee is easy to happen
Rupture, and the hardness of tube body upon bending is inadequate, the problem of being easily broken off.
To realize the above-mentioned technical purpose, the technical solution adopted in the utility model is as follows:
A kind of Tensible flexible high density polyethylene (HDPE) communication tube, including high-density polyethylene layer, the high density polyethylene (HDPE)
It is equipped with several flexible steel wires in layer, fixing layer is provided on the inside of the high-density polyethylene layer, is equipped on the inside of the fixing layer
Fixed frame, the fixed frame include middle bar and fin, and the fixing layer inner wall offers fixing groove in fin corresponding position, described
Fin free end is fastened in fixing groove, and uniform intervals offer several notches on the fixed frame, and the middle bar outer wall is in phase
Arc groove is axially offered between adjacent two fins, is arranged with protective case in the arc groove.
Utility model by adopting the above technical scheme, in use, protective case is fastened in arc groove, then protective case
Connection fixed frame is inserted into communication tube together, finally communications optical cable, cable is threaded through in protective case, in high-density polyethylene layer
Flexible steel wire so that communication tube have good tensile property；It is supported inside communication tube by fixed frame, so that communication tube has
There is good crushing resistance, make communication tube when bearing external pressure, there is good ring stiffness；Meanwhile on fixed frame uniformly between
Several notches set are separated, enable fixed frame itself that there is flexible, while avoidable communication tube bending angle is excessive, leads
The compression strength of communication tube bending place is caused to be affected.
It further limits, flame-retardant layer is equipped between the high-density polyethylene layer and fixing layer.Such structure design, can
To play good fire retardation, communications optical cable, cable machinery can be protected more fully hereinafter.
It further limits, lubricant layer is equipped in the protective case.Such structure design, more convenient optical cable, cable are worn
In protective case, practicability is stronger.
It further limits, the middle bar and fin are integrally formed.Such structure design, structural strength are higher.
It further limits, also is provided with lubricant layer in the fixing groove.Such structure design, so that the installation of fixed frame is more
Add conveniently.
It further limits, the fin is six.Such structure design, can arrange six roots of sensation protective case in communication tube,
Practicability is stronger.
