In there is an installation cavity, one external protection of installation and a hollow layer in the installation cavity, the external protection and hollow
The rounded hollow structure in section of layer, isometric with entire serving, the external protection and hollow layer are both ends
Closed structure has closed first air storing cavity inside external protection, has one closed the in the hollow layer
Two air storing cavities, the both ends of first air storing cavity are respectively arranged with an outlet hole, and power supply core wire passes through outlet hole and gluing sealing
Fixed, the external protection is located at the top of hollow layer, and power supply core wire is built in the first air storing cavity, and the external protection is in
Conducting is connected by one or more gas-guide tube between dead level.
The external protection is set to installation cavity by one or more gas-guide tube jack-up as a preferred technical solution,
On top surface.
The external protection and hollow layer active installation are in installation cavity as a preferred technical solution, hollow layer
Bottom is contacted with installation cavity bottom surface, and one or more air guide spire is risen and vacantly set external protection using gas-guide tube by hollow layer
It is placed in the top of hollow layer.
It is provided with weight body in second air storing cavity as a preferred technical solution, which is metal weights body.
Gassy, hollow layer are filled out in first air storing cavity and the second air storing cavity as a preferred technical solution,
Top and the bottom of external protection be equidistantly provided with more than one connector, the both ends of gas-guide tube are respectively charged into even
In connector and gluing sealing is fixed.
The external protection and hollow layer are all made of the elasticity with elastic deformability as a preferred technical solution,
Rubber material is made.
The beneficial effects of the present invention are: the present invention can be always ensured that power supply core wire is in the top position of entire power supply line
It sets, will not first be acted on power supply core wire when being pressurized, shearing, can be very good to carry out buffer protection, avoid directly shearing
And it squeezes；
The configuration of the present invention is simple has extraordinary anti-pressure ability, and can adequately protect internal power supply after compression
Core wire prevents power supply core wire damaged, is mainly used for naked be exposed on the external on ground and uses.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Fig. 1 is overall structure diagram of the invention；
Fig. 2 is inner section schematic diagram of the invention.
Specific embodiment
As depicted in figs. 1 and 2, this power transmission line, including serving 8 have an installation cavity 4, installation in serving 8
One external protection 6 of installation and a hollow layer 9 in chamber 4；
The rounded hollow structure in the section of external protection 6 and hollow layer 9, isometric with entire serving 8, outer guarantor
Sheath 6 and hollow layer 9 are structure closed at both ends, have closed first air storing cavity 7 inside external protection, hollow
There is closed second air storing cavity 2 in layer 9；
The both ends of first air storing cavity 7 are respectively arranged with an outlet hole, and power supply core wire 5 passes through outlet hole and gluing sealing is solid
It is fixed,；
External protection 6 is located at the top of hollow layer 9, and power supply core wire 5 is built in the first air storing cavity 7, and external protection is in
Conducting is connected by one or more gas-guide tube 3 between dead level, wherein external protection 6 is jacked up by one or more gas-guide tube 3
It is set on the top surface of installation cavity.
In in installation cavity, 9 bottom of hollow layer connects with 4 bottom surface of installation cavity for external protection 6 and 9 active installation of hollow layer
One or more air guide spire is risen and external protection is vacantly set to the top of hollow layer using gas-guide tube by touching, hollow layer 9.
In the present embodiment, it is provided with weight body 1 in the second air storing cavity 2, which is metal weights body, due to the bottom of at
The built-in weight body 1 of the hollow layer in portion, so that entire hollow layer is always positioned at the bottom of serving, and since external protection passes through
One or more gas-guide tube is connected to the hollow layer of bottom, therefore external protection and entire power supply core wire are always positioned at serving
Upper end position, when top be pressurized when, will not immediately clip to top power supply core wire, only can first shear, squeeze bottom
Hollow layer.
Wherein, gassy, the top of hollow layer 9 and outer protection are filled out in the first air storing cavity 7 and the second air storing cavity 2
The bottom of layer 6 is equidistantly provided with more than one connector, and the both ends of gas-guide tube 3 are respectively charged into simultaneously gluing is close in connector
Sealing is fixed.When top is pressurized, entire serving is pressurized, so that the hollow layer of bottom is pressurized, after hollow layer is pressurized, the second storage
Gas in air cavity can exit into the first air storing cavity from one or more gas-guide tube, so that the first gas storage intraluminal inflation,
So that the volume of external protection becomes larger, increase internal volume after expansion, and then preferably protection power source core wire.
Wherein, external protection 6 and hollow layer 9 are all made of the elastic rubber material with elastic deformability and are made.By
In using elastic rubber material, therefore it can effectively expand and become larger after being squeezed, cushion performance is increased with this.
The beneficial effects of the present invention are: the present invention can be always ensured that power supply core wire is in the top position of entire power supply line
It sets, will not first be acted on power supply core wire when being pressurized, shearing, can be very good to carry out buffer protection, avoid directly shearing
And it squeezes；
The configuration of the present invention is simple has extraordinary anti-pressure ability, and can adequately protect internal power supply after compression
Core wire prevents power supply core wire damaged, is mainly used for naked be exposed on the external on ground and uses.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.Therefore, of the invention
Protection scope should be determined by the scope of protection defined in the claims.
