Description
Technical field
The utility model relates to communication technical field, especially a kind of scalable cable protection pipe.
Background technology
Cable is a kind of important carrier of the communication technology; in its erection or when burying; all need at the sheathed one deck cable protection pipe of its appearance; conveniently install, the cable protection pipe section of one-tenth first place connects, but when removing a certain section in the middle of it; because of the end to end property of cable protection pipe; can only remove or damage a wherein part successively, cannot dismantle flexibly, and wasting manpower and material resources.
Summary of the invention
Problem to be solved in the utility model is to provide the telescopic cable protection pipe in a kind of head and the tail two ends.
For solving the problems of the technologies described above; the technical solution adopted in the utility model is: a kind of scalable cable protection pipe; comprise inner layer pipe, connector and outer tube; described inner layer pipe is fixed on the inner surface of described outer tube by described connector; and this inner layer pipe can be rotated around its axis, described outer tube comprises outer tube body and is positioned at the expansion joint at these outer tube body two ends.
Further, described connector comprises bearing and blocks circle.
Further, at least two, described bearing, is separately fixed on described outer tube inwall, and described inner layer pipe is through this bearing.
Further, the described circle that blocks comprises and blocks ring and fixture, described to block ring identical with the end face at described inner layer pipe tube wall two ends, and the inner of described fixture is fixedly connected with described outside of blocking ring, and the outside of described fixture is fixed in described bearing or outer tube.
Further, described outer tube ecto-entad comprises corrosion-resistant coating, watertight composition and supporting layer successively, and described expansion joint is arranged on the two ends of described supporting layer.
Further, the outer surface at described outer tube body two ends is provided with slide slot, and described expansion joint comprises flange connector and extension sleeve, and described extension sleeve one end is fixedly connected with described flange connector, and the other end is set on described slide slot.
Further, described inner layer pipe is slightly longer than described outer tube principal length, makes inner layer pipe slightly stretch out the two ends of described outer tube body.
The advantage that the utility model has and good effect are: adopt technique scheme; the utility model makes cable can freely rotate in the process stretching into cable protection pipe; and the dismounting of cable protection pipe is more flexible, also advantageously overhauls in the timing of cable.

In figure: 1, inner layer pipe 2, connector 3, outer tube 21, bearing 22, block circle 221, block ring 222, fixture 31, outer tube body 32, expansion joint 311, slide slot 321, flange connector 322, extension sleeve
Embodiment
Below with reference to the accompanying drawings and specific embodiment detailed description is made to the utility model.
As illustrated in fig. 1 and 2, the utility model comprises inner layer pipe 1, connector 2 and outer tube 3.
Inner layer pipe 1 is fixed on the inner surface of outer tube 3 by connector 2, and this inner layer pipe 1 can be rotated around its axis, so that can not there is torsion excessive phenomenon when cable penetrates this cable protection pipe.
Connector 2 comprises bearing 21 and blocks circle 22.
21 at least two, bearing, is separately fixed on outer tube 3 inwall, and inner layer pipe 1 is through this bearing 21, and this inner layer pipe 1 is freely rotated under the support of this bearing 21.
Block circle 22 to comprise and block ring 221 and fixture 222, block ring 221 identical with the end face at inner layer pipe 1 tube wall two ends, make this block ring 221 just to overlap with the end face at inner layer pipe 1 two ends, in order to block inner layer pipe 1, the inner of fixture 222 is fixedly connected with the outside of blocking ring 221, the outside of fixture 222 is fixed in bearing 21 or outer tube 3, in order to fixedly to block ring, prevents inner layer pipe 1 from sliding along its axis direction.
Outer tube 3 comprises outer tube body 31 and is positioned at the expansion joint 32 at these outer tube body 31 two ends.
Outer tube 3 ecto-entad comprises corrosion-resistant coating, watertight composition and supporting layer successively, and expansion joint 32 is arranged on the two ends of supporting layer.
The outer surface at outer tube body 31 two ends is provided with slide slot 311, expansion joint 32 comprises flange connector 321 and extension sleeve 322, extension sleeve 322 one end is fixedly connected with flange connector 321, the other end is set on slide slot 311, expansion joint 32 can outside tube body 31 be slidably reciprocated, adjustment outer tube 3 length along its axis direction.
Extension sleeve 322 inner surface contacts with slide slot 311 frosted, so that the sealing that extension sleeve 322 keeps it certain while sliding on slide slot 311.
Inner layer pipe 1 is slightly longer than outer tube body 31 length, makes inner layer pipe 1 slightly stretch out the two ends of outer tube body 31.
The course of work of the present utility model is: first, cable is passed by inner layer pipe 1 inside, in the process of passing, first fix inner layer pipe 1 with hand, make electric cable rotary advance, after cable passes, hand unclamps inner layer pipe 1, inner layer pipe 1 rotates under the twisting force of cable, until cable no longer includes torsion, the cable that makes of so operation passes multi-cable protection tube;
Secondly, adjust the length of every root cable protection pipe, make extension sleeve 322 stretch out certain length slightly outward;
Finally, adjacent cable protection tube is linked together by flange connector 321 head and the tail.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present invention.All equalizations done according to the utility model scope change and improve, and all should still belong within this patent covering scope.
