Description
Technical field
The utility model relates to a kind of plastic pipes, in particular to a kind of modified MPP power cable of removable repairing formula to protect
Pillar.
Background technique
MPP is widely used due to good intensity, toughness and more excellent electrical insulating property and is made power cable protecting pipe.
In order to improve the modification that its performance carries out fire retardancy, but traditional MPP pipe is needed in connection using fixing piece or progress
Welding, so that construction efficiency is lower, higher cost, especially welding are inconvenient in later maintenance, it usually needs tubing is cut,
Or directly homogeneous tube is more preferable.
Utility model content
The purpose of this utility model is to provide for a kind of modified MPP power cable protecting pipe of removable repairing formula, the pipe
Material has good toughness, intensity and insulating properties, is detachably assembled by multiple single tubes, is conducive to the efficiency for improving tubing construction
With construction flexibility, while be convenient for the tubing later period maintenance.
In order to achieve the above object, the utility model provides following technical solution: a kind of modified MPP of removable repairing formula
Power cable protecting pipe, including the tube body being detachably connected by least two sections of single tubes, one end of the single tube is equipped with interior connection ring,
The other end is equipped with outer connection ring, and the interior connection ring is equipped at least two fixing grooves, and the outer connection ring is equipped with and fixation
The fixed hole that slot matches, the fixing groove and fixed hole form the connection between single tube after filling in fixed pin, described outer
The inner edge of connection ring is equipped with chamfering, and the outer wall and chamfering of the interior connection ring form sealing ring hole, be equipped in the sealing annular distance
Water-swellable sealing ring.
It is further preferred that the thickness of the interior connection ring is greater than or equal to outer connection ring.
It is further preferred that the fixed pin is equipped with sealed thin pad, and sealed thin pad close to the side of outer connection ring one end
Chamfering slope is equipped with close to one end of interior connection ring.
It is further preferred that the outer connection ring is equipped with looping snail groove, twist-on has covering on the looping snail groove
The seal closure of fixed hole.
The utility model has the beneficial effects that the tubing is efficiently detachably assembled by multiple single tubes, be conducive to improve pipe
The efficiency and construction flexibility of material construction, while being convenient for the maintenance in tubing later period.

Specific embodiment
We are in conjunction with attached drawing to a kind of modified MPP power cable protection of removable repairing formula described in the utility model below
Pipe is described further.
As shown in Figure 1 to Figure 3, the modified MPP power cable protecting pipe of a kind of removable repairing formula of the present embodiment, including
The tube body 1 being detachably connected by least two sections of single tubes 2, one end of the single tube 2 are equipped with interior connection ring 3, and the other end is equipped with outer company
Connect ring 4, the interior connection ring 3 is equipped at least two fixing grooves 31, and the outer connection ring 4 is equipped with to match with fixing groove
Fixed hole 41, the fixing groove 31 and fixed hole 41 form the connection between single tube 2, the outer company after filling in fixed pin 5
The inner edge for connecing ring 4 is equipped with chamfering 42, and the outer wall and chamfering 42 of the interior connection ring 3 form sealing annular distance 6, the sealing annular distance 6
It is interior to be equipped with water-swellable sealing ring 7.The thickness of the interior connection ring 3 is greater than or equal to outer connection ring 4.The fixed pin 5 is close
The side of outer 4 one end of connection ring is equipped with sealed thin pad 51, and sealed thin pad 51 is equipped with chamfering slope close to one end of interior connection ring
52。
The service condition of the tubing is substantially as follows: the tubing is made up of removable single tube, the company between tubing
The connection between i.e. single tube is connect, the interior connection ring of single tube is inserted into the outer connection ring of another single tube, and makes fixing groove and fix logical
Hole alignment is inserted into fixed pin and single tube combination links together.When needing to carry out the maintenance and replacement of tubing, it is only necessary to
Fixed pin is extracted, single tube will be replaced.By sealed thin pad improve fixed effect of the fixed pin on fixed hole and
Sealing effect, by chamfering slope convenient for fixed pin insertion.It is thin one layer of plastics can be wrapped up in outer wall after the completion of single tube connection
Film improves the protectiveness to cable to improve integral sealing effect.
In the present embodiment, the outer connection ring 4 is equipped with looping snail groove 8, and twist-on has covering on the looping snail groove 8
The seal closure 9 of fixed hole.The leakproofness of single tube junction is improved by seal closure, improves protecting effect.
The protection scope of the utility model is not limited to above embodiments and its transformation.Those skilled in that art are with this implementation
The conventional modification and replacement carried out based on the content of example, belongs to the protection category of the utility model.
