Buried protection pipe.
To achieve the goals above, the utility model uses following technical solution：A kind of buried protection of power cable
Pipe, including outside protective pipe, one end of the outside protective pipe are fixed with outer pipe connector, and outer pipe connector is internally provided with the
One gasket, the outside protective pipe are internally provided with internal protective cover pipe, cross have been placed equidistant with inside the internal protective cover pipe
Supporting rack, the side between the outside protective pipe and interior protection pipe positioned at outer pipe connector is equidistantly connected with outer support bar, described
The engaging slot that cooperation outer support bar uses is offered on interior protection pipe appearance wall, described interior protection pipe one end is connected with inner tube connection
Head, and interior pipe connector is internally provided with the second gasket, and toroidal frame is socketed on the outside protective pipe, is welded on the toroidal frame
It is connected to fixed block, and offers bolt hole on fixed block.
As further describing for above-mentioned technical proposal：
There are four the outer support bar is arranged altogether, and four outer support bars are engaged by engaging slot with cross supporting frame respectively
Connection.
As further describing for above-mentioned technical proposal：
The interior protection pipe and outside protective pipe equal length, and the internal diameter of interior protection pipe is equal to the one of outside protective pipe internal diameter
Half.
As further describing for above-mentioned technical proposal：
The outside protective pipe is integrated with outer support bar.
As further describing for above-mentioned technical proposal：
There are two the toroidal frame is arranged altogether, and two toroidal frames are symmetrical about the vertical center line of outside protective pipe.
In the utility model, the buried protection pipe is made of outside protective pipe and interior protection pipe first, setting in interior protection pipe
There is cross supporting frame, the outer support bar that cooperation cross supporting frame uses is provided between outside protective pipe and interior protection pipe, effectively
The intensity for increasing outside protective pipe prevents it to be squeezed the damage that deforms, and improves its service life, secondly in interior protection pipe
Interior protection pipe is equidistantly divided into four parts by the setting of cross supporting frame, will not mutually be tangled when it being made to place cable, then have setting
There are outer pipe connector and interior pipe connector, convenient for the connection of be connected outside protective pipe and interior protection pipe, the first gasket and second close
The setting of packing, improves the leakproofness connected between outside protective pipe and interior protection pipe, and outer support bar is arranged in outer tube connection
The side of head so that being located at the inner tube of outside protective pipe junction will not effectively be prevented from being connected by the stress of outer support bar
Interior protection pipe between be squeezed deformation, cause its leakproofness not tight, generate leak the case where, it is buried to further improve this
The leakproofness of protection pipe and the stability used.
