Description
Technical field
The utility model belongs to single-wall corrugated pipe technical field, and in particular to a kind of stretching structure of single-wall corrugated pipe.
Background technique
PVC single-wall corrugated pipe is to form using PVC as primary raw material through extrusion-blown modling, and surfaces externally and internally is corrugated, and
Using the structure of annular groove, the rigidity of hard PVC pipe and the flexibility of hose are had both, has the characteristics that can be used as pre-buried in just with soft
The casing of electric wire, in the actual construction process, the length of electric wire can be adjusted as needed, and single-wall corrugated pipe is usually all
With certain specification, the length that You Duogen single-wall corrugated pipe connects the built-in electric wire casing to be formed can not follow the length of electric wire
It is adjusted, therefore, urgent need is provided a kind of stretching structure and is adjusted with the length to built-in electric wire casing.
Utility model content
The purpose of this utility model is that: when for above-mentioned existing single-wall corrugated pipe as built-in electric wire casing, length
The problem of can not adjusting, the utility model provide a kind of stretching structure of single-wall corrugated pipe.
The technical solution adopted in the utility model is as follows:
A kind of stretching structure of single-wall corrugated pipe, including at least two single-wall corrugated pipes, and by adjacent two single wall waves
The expansion joint of line pipe connection, it includes wave crest and trough that single-wall corrugated pipe, which includes ripple in the tube body of ripple setting, on tube body,
The expansion joint includes the sleeve of both ends open, and sleeve diameter is to equipped with equally distributed snap ring, the internal diameter and wave crest of snap ring
Outer diameter it is consistent；The both ends of the tube body are equipped with interface section, and the outer wall of interface section is equipped with snap-gauge, is formed between adjacent snap ring
With the card slot of snap-gauge cooperation, snap ring inside is provided with the notch passed through for snap-gauge；The both ends of the sleeve are equipped with sealing ring, close
Seal is equipped with the through-hole passed through for tube body, and the aperture of through-hole is less than the outer diameter of wave crest.
Two single-wall corrugated pipes of the utility model are by sleeve connection, and interface section is arranged in tube body both ends, by interface section
Snap-gauge and sleeve upper snap ring formed card slot realize be clamped.It is needing to connect the pre-buried electricity formed to by more single-wall corrugated pipes
When thread casing length is adjusted, sleeve is kept to fix, rotates single-wall corrugated pipe, so that snap-gauge is located at the indentation, there of snap ring, then
The single-wall corrugated pipe is twitched, then it is moved in sleeve, and after being moved to suitable position, rotation makes snap-gauge be located at card again again
In slot.
Also sealing ring is arranged at the both ends of sleeve in the utility model, and aperture is arranged on sealing ring and is less than wave crest outer diameter
Through-hole avoids single-wall corrugated pipe rotation in normal use so that generating frictional resistance between sealing ring and wave crest, guarantees to stablize
Property, only when needing adjustment length, single-wall corrugated pipe rotation is controlled by artificial or external force.In addition, sealing ring also assures this
The leakproofness of stretching structure.
Further, snap-gauge is two, and symmetrical.
Further, sealing ring is rubber ring.
Further, notch extends to sleeve lining, and the sleeve of indentation, there is equipped with visual windows.Visual windows are considerable
It examines whether snap-gauge is located at indentation, there, facilitates adjustment length.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are: simultaneously by setting sleeve
Equally distributed snap ring is set in sleeve, while interface section is set at tube body both ends, snap-gauge is set in interface section, utilizes snap-gauge
It realizes and connects with the card slot that snap ring is formed, and notch is set in snap ring, by rotating single-wall corrugated pipe, snap-gauge is made to be located at snap ring
Length can be adjusted in indentation, there, and when solving existing single-wall corrugated pipe as built-in electric wire casing, length can not be adjusted
The problem of section, and good airproof performance.

Specific embodiment
All features disclosed in this specification can be with any other than mutually exclusive feature and/or step
Mode combines.
It elaborates below with reference to Fig. 1, Fig. 2 to the utility model.
Embodiment 1
A kind of stretching structure of single-wall corrugated pipe, including at least two single-wall corrugated pipes, and by adjacent two single wall waves
The expansion joint of line pipe connection, single-wall corrugated pipe include the tube body being arranged in ripple, and the ripple on tube body includes wave crest 3 and trough
2, the expansion joint includes the sleeve 1 of both ends open, and equally distributed snap ring 8, the internal diameter of snap ring 8 are radially provided in sleeve 1
