Portion's side wall, and extruding item is also equipped in the groove；The inside of the air guide tube body is additionally provided with and air guide tube body
Parallel filling hole；Glass fiber is filled in the filling hole.
Preferably, the air guide tube body is integrally formed with supporting rack and is molded.
Preferably, the gas-guide tube and supporting rack are injection molding respectively, and supporting rack is detachable mechanism, described
Four ends of supporting rack be both provided with arc support plate, and the inner wall of the gas-guide tube is provided with and arc support plate phase
The arc chute of adaptation, the arc support plate can be mounted in arc chute accordingly.
Preferably, the extruding item is at least provided with ten, and the extruding item is set as the circle of rubber making
Shape squeezes layering structure.
Preferably, there are four the filling hole is arranged altogether, and be uniformly arrangement.
Advantageous effect：The invention has the advantages that：
(1) a criss-cross supporting rack is arranged in the inside of gas-guide tube in the present invention, inside supporting rack supporting pipeline, increases
The anti-pressure ability of gas-guide tube, lateral wall are equipped with extruding item by the way that groove is arranged in groove, when encapsulating cable in this way, squeeze item
External conductor insulating layer or other layer structures can first be pressed in rubber making extruding item, when outside apply pressure when, squeeze
Press strip generates certain deformation and eliminates the extruding force, prevents from damaging gas-guide tube by pressure, and be also filled with glass fiber on gas-guide tube,
The bending tolerance degree of gas-guide tube is increased, combination settings can greatly increase the service life of cable；
(2) supporting rack of the invention could be provided as integrated formed structure and may be set to be detachable structure；One at
The compatible degree of both type structures is more preferable, and anti-pressure ability is also stronger；And detachable structure is convenient for recycling, by arc groove and
The design installation and removal of arc chute are also very convenient.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
