Abstract
The utility model relates to a kind of COD pipe connections, comprise the first housing and the second housing that match, the first housing and the second housing are semicircle tubulose, the two forms a tubular shell after coordinating, the inner surface two ends of tubular shell are provided with helical raised, the dual-side of described the first housing and the second housing is equipped with outward extending flange, and flange is provided with plural bolt hole.COD pipe connections of the present utility model is formed in one, and preparation is simple, easy to use, can be widely used in the tubing interface of COD pipe, has good fastness and sealing.
Description
Technical field
The utility model relates to a kind of COD pipe connections.
Background technology
Corrugated optical cable protection tube (corrugated optic duct), is called for short COD, and it is the entirety being made up of multiple cable tubes of inside and outer tube, and COD is the six hole integral tubes of once manufacturing shaping by new and high technology technique.Inner and outer tubes all adopt HDPE (high density polyethylene (HDPE)) to make, and have the elasticity of height, although be provided with most inner tubes in outer tube, still can be good at being wrapped on pipe frame.Because material is non-conductive, insulating properties is high, is desirable cable duct.The thermal expansion of outward appearance and contraction phase are worked as lower than conventional catheter systems in addition, and because the raw material of inner and outer pipe are the same, remain unified ratio, COD can bending freely, firmly bending can reach 90 degree, and even larger angle is come bending or stretching without any need for special instrument.Running at the construction field (site) barrier can detour, and the most important thing is, COD can import at most 75% the optical cable that diameter is diameter of inner pipe, and conventional tube can only import 50% at most.
COD pipe is special spiral-shaped, and it has strengthened the anti-pressure ability of the straight wall pipe of conventional P E, and its anti-pressure ability is 8-10 times of conventional tube, has improved validity and elasticity, especially earthquake is occurring, and the situation such as subside can play good safety assurance.In use, conventionally the docking of two COD pipe need to be lengthened, in prior art, conventionally adopt adhesive tape that two pipes are connected together, but adhesive tape easily comes off, fastness and sealing are all inadequate.
Summary of the invention
The purpose of this utility model is to provide a kind of COD pipe connections, while making it be applied to the docking of COD pipe, has good fastness and sealing.
Technical scheme
A kind of COD pipe connections, comprise the first housing and the second housing that match, the first housing and the second housing are semicircle tubulose, the two forms a tubular shell after coordinating, the inner surface two ends of tubular shell are provided with helical raised, the dual-side of described the first housing and the second housing is equipped with outward extending flange, and flange is provided with plural bolt hole.
As preferably, the inner surface two ends of described the first housing and the second housing are respectively provided with one deck fluid sealant, are preferably heat shrink films.
As preferably, the length of described the first housing and the second housing is 35-42cm, and internal diameter is identical with the external diameter of COD pipe.
COD pipe connections of the present utility model is formed in one, and preparation is simple, easy to use, can be widely used in the tubing interface of COD pipe, has good fastness and sealing.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model the first housing;
Fig. 2 is the sectional view of the utility model COD pipe connections.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As depicted in figs. 1 and 2, COD pipe connections of the present utility model, comprise the first housing and 1 second housing 2 that match, the first housing 1 and the second housing 2 are semicircle tubulose, the two forms a tubular shell after coordinating, the inner surface two ends of tubular shell are provided with helical raised 3, the dual-side of described the first housing and the second housing is equipped with outward extending flange 4, flange is provided with plural bolt hole 5, the inner surface two ends of described the first housing 1 and the second housing 2 are respectively provided with one deck fluid sealant 6, described fluid sealant 6 is heat shrink films, gram further enhanced leaktightness effect, the length of described the first housing and the second housing is 38cm, internal diameter is identical with the external diameter of COD pipe.
COD pipe connections of the present utility model is formed in one, and preparation is simple, easy to use, can be widely used in the tubing interface of COD pipe, has good fastness and sealing.
