In figure: pipe, 201-demarcation strip, 202-lug, 300-flange, 301-first through hole, 302-scrobicular ring, 400-sealing ring, 401-second through hole, 402-bulge loop in 100-outer tube, 101-support ring, 200-.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of cable protection pipe, comprises outer tube 100 and the interior pipe 200 of concentric setting; Described outer tube 100 two ends are all fixedly installed flange 300; The outer wall of described outer tube 100 has been intervally arranged one group of support ring 101; The external diameter of described support ring 101 is identical with the external diameter of flange 300.
The setting of support ring 101, not only increase the intensity of pipe, increase the anti-pressure ability of pipe, the more important thing is, because support ring 101 external diameter is identical with the external diameter of flange 300, support ring 101 and flange 300 bear the effect of torsion equally, reduce the moment of torsion of pipeline, improve the adaptability of pipeline.
It is inner that described interior pipe 200 is sheathed on outer tube 100; The outer wall axial restraint of described interior pipe 200 is provided with a component dividing plate 201; Within described demarcation strip 201 pipe 200 axle center centered by put annular array; The radial outer end of described demarcation strip 201 touches outer tube 100 inwall.
As preferably, the inner space of outer tube 100 is divided into some regions by demarcation strip 201, is convenient to place different cables, makes the arrangement of cable more orderly.On the other hand, demarcation strip 201 provides support force for outer tube 100, improves the anti-bending strength of cable protection pipe.
As preferably, described demarcation strip 201 has 5 pieces, and the angle of cut of adjacent demarcation strip 201 is 72 °; Adjacent supports ring 101 be spaced apart 15cm ~ 25cm.The cable protection pipe performance of this specification is comparatively balanced, and meet most of demand in market, versatility is good.
The axial outer end of described demarcation strip 201 is provided with inlay card in the lug 202 of flange 300.As preferably, at the inner sheathed two interior pipes 200 of an outer tube 100.Interior pipe 200 inserts from outer tube 100 two ends respectively, and interior pipe 200 inner end is provided with sawtooth, is convenient to two interior pipe 200 buckles.After adjacent flanges 300 seals, the lug 202 of outer tube 100 offsets with the lug 202 of another root outer tube 100, thus fixing outer tube 100.
A kind of cable protection pipe, also comprises the sealing ring 400 be located between adjacent flanges 300; Described flange 300 is provided with the first through hole 301; Described sealing ring 400 is provided with second through hole 401 corresponding with the first through hole 301.Screw is through the first through hole 301 and the second through hole 401, thus fixing adjacent flange 300 and sealing ring 400.
Described sealing ring 400 is provided with one group of bulge loop 402; The joint face of described flange 300 is provided with one group of scrobicular ring 302 corresponding with bulge loop 402; The degree of depth of described scrobicular ring 302 is greater than the height of bulge loop 402; The width of described scrobicular ring 302 is greater than the width of bulge loop 402.
When adjacent flanges 300 misplacing slightly because bearing the effect of moment of flexure, there is flexible sealing ring 400 and still can fill gap between flange 300, ensureing the sealing of pipeline.In addition, after sealing ring 400 seeps water, volume increases, and the expansive force between adjacent flanges 300 is increased, and reaches the effect preventing from seeping water.Unnecessary moisture also can be received in gap between scrobicular ring 302 and bulge loop 402, protects pipeline further.
The radial outer end of described second through hole 401 is at least provided with a bulge loop 402, prevents screws contact moisture thus corrosion inefficacy.The radial inner end of described second through hole 401 is at least provided with two bulge loops 402, improves the sealing property of sealing ring 400.
The utility model is illustrated according to embodiment, and under the prerequisite not departing from present principles, this device can also make some distortion and improvement.It should be pointed out that and all drop on the technical scheme that all employings are equal to replacement or the mode such as equivalent transformation and obtain in protection range of the present utility model.
