Description
Technical field
The present invention relates to power wiring tubing, particularly relate to a kind of New corrugated pipe.
Background technology
Power cable embedment underground needs pipe box to protect, and planomural tubing is the most gradually eliminated because structural strength is low, expend the shortcomings such as material, and corrugated tube is the preferable tubing that a kind of application is day by day universal.This utility model that notification number is CN202252578U provides the attachment structure of a kind of corrugated tube and flange, including corrugated tube and the flange being positioned at corrugated tube two ends, each flange is provided with screw, corrugated tube includes stage casing corrugated tube, left section of corrugated tube and right section of corrugated tube, left section of corrugated tube and right section of corrugated tube lay respectively at the both sides of stage casing corrugated tube, the end of left section of corrugated tube and the end of right section of corrugated tube are respectively provided with straight section, the end of each straight section is fixedly connected with a flange respectively, the diameter of the left section of each crest of corrugated tube is identical with the diameter of the right section of each crest of corrugated tube and less than the diameter of stage casing corrugated tube crest, stage casing corrugated tube, left section of corrugated tube, right section of corrugated tube and straight section are formed in one.This utility model on the one hand add flange and and stage casing corrugated tube between distance, bolt can be installed easily on flange, simultaneously because left section of corrugated tube and right section of corrugated tube have the effect of reinforcement, therefore improve the bonding strength between stage casing corrugated tube and flange.It is insufficient to be: by Flange joint between corrugated tube, need to be bolted, and connects inconvenience.
Utility model content
The purpose of this utility model is to solve the problem existing for prior art, finds a kind of New corrugated pipe, can more easily be connected with each other between corrugated tube.
nullIn order to realize described purpose，This utility model one New corrugated pipe，Including bellows body，Described bellows body includes stage casing corrugated tube、Left section of corrugated tube and right section of corrugated tube，Left section of corrugated tube and right section of corrugated tube lay respectively at the both sides of stage casing corrugated tube，The left part of left section of corrugated tube and the right part of right section of corrugated tube are respectively equipped with annular connecting portion，Connecting portion outer wall is provided with external screw thread，The external diameter of the left section of each crest of corrugated tube is identical with the external diameter of the right section of each crest of corrugated tube and less than the external diameter of stage casing corrugated tube crest，The external diameter of the left section of each trough of corrugated tube、The external diameter of the external diameter trough each with stage casing corrugated tube of the right section of each trough of corrugated tube is identical，Described stage casing corrugated tube、Left section of corrugated tube、Right section of corrugated tube and annular connecting portion are one-body molded，Connect on the connecting portion of left section of corrugated tube and have annulus cylindricality adapter sleeve，Adapter sleeve inwall is provided with the female thread coordinated with external screw thread.
Preferably, described adapter sleeve left part is provided with the annular stopper portions downwardly extended, and the internal diameter of stopper portions is more than the crest external diameter of left section of corrugated tube.Such structure so that stopper portions can move along left section of corrugated tube, and can be stopped by the connecting portion of left section of corrugated tube, prevents adapter sleeve from separating with bellows body.
Preferably, the external diameter of described adapter sleeve is identical with the external diameter of stage casing corrugated tube crest.Such structure, it is simple to burying of corrugated tube is put.
Following Advantageous Effects can be obtained: can be connected easily by adapter sleeve between two corrugated tubes by implementing this utility model, and without using instrument when connecting.

Detailed description of the invention
For the ease of the understanding of those skilled in the art, below in conjunction with specific embodiment, this utility model is further described:
nullAs shown in figures 1-4，A kind of New corrugated pipe，Including bellows body，Bellows body includes stage casing corrugated tube 2、Left section of corrugated tube 1 and right section of corrugated tube 3，Stage casing corrugated tube 2、Left section of corrugated tube 1 and right section of corrugated tube 3 all comprise crest and trough，Left section of corrugated tube 1 and right section of corrugated tube 3 lay respectively at the both sides of stage casing corrugated tube 2，The left part of left section of corrugated tube 1 and the right part of right section of corrugated tube 3 are respectively equipped with annular connecting portion 4，Connecting portion 4 on left section of corrugated tube 1 is identical with connecting portion 4 structure size on right section of corrugated tube 3，Connecting portion 4 outer wall is provided with external screw thread 41，The external diameter of the left section of each crest of corrugated tube 1 is identical with the external diameter of the right section of each crest of corrugated tube 3 and less than the external diameter of stage casing corrugated tube 2 crest，The external diameter of the left section of each trough of corrugated tube 1、The external diameter of the external diameter trough each with stage casing corrugated tube 2 of the right section of each trough of corrugated tube 3 is identical，Stage casing corrugated tube 2、Left section of corrugated tube 1、Right section of corrugated tube 3 and annular connecting portion 4 are one-body molded，Connect on the connecting portion 4 of left section of corrugated tube 1 and have annulus cylindricality adapter sleeve 5，Adapter sleeve 5 inwall is provided with the female thread 51 coordinated with external screw thread 41.As shown in Figure 3 and Figure 4, as a kind of preferred structure, adapter sleeve 5 left part is provided with the annular stopper portions 52 downwardly extended, the internal diameter of stopper portions 52 is more than the crest external diameter of left section of corrugated tube 1, stopper portions can be moved along left section of corrugated tube, and can be stopped by the connecting portion of left section of corrugated tube, prevent adapter sleeve from separating with bellows body.As another kind of preferred structure, the external diameter of adapter sleeve 5 is identical with the external diameter of stage casing corrugated tube 2 crest, and connecting portion 4 external diameter on adapter sleeve 5 internal diameter, left section of corrugated tube 1, connecting portion 4 external diameter on right section of corrugated tube 3 are identical.The length of female thread 51 is the twice of external screw thread 41 length.
