Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipeline structure, and particularly relates to a corrugated pipe with a split. BACKGROUND

[0002] In order to improve the waterproof performance of the cable, a corrugated pipe structure is usually arranged on the outer sleeve of the cable. However, since the corrugated pipe needs to be as close as possible to the cable group to reduce the occupied space, it is difficult for the cable to pass into the corrugated pipe from the end of the corrugated pipe. In addition, the side wall of the corrugated pipe has a strip structure, and it is also difficult to tightly adhere to the surface of the cable or the outer surface of the pipe body of the lead-out cable at the end, so that the waterproof performance of the two ends of the corrugated pipe is poor. SUMMARY

[0003] The present application aims to provide a corrugated pipe with a split, which has better end insertion and waterproof effect.

[0004] To achieve the above purpose, the present application provides a corrugated pipe with a split: a corrugated pipe body, both ends of the corrugated pipe body have a connecting end sleeve, the connecting end sleeve is provided with a through inner and outer wall of the cutting seam, the outer side of the connecting end sleeve is provided with a corrugated close groove in communication with the inner side wall of the cutting seam, and the other inner side wall of the cutting seam has a corrugated close piece, which is adapted to be matched with the corrugated close groove and can effectively prevent fluid from entering the corrugated pipe through the cutting seam.

[0005] As a preferred, the cutting seam extends to the end face of the connecting end sleeve, so that the connecting end sleeve can be turned outwards at the end of the corrugated pipe to form an expanded and larger port, thereby facilitating the insertion of the cable structure.

[0006] As a preferred, the extension direction of the cutting seam is parallel to the axis of the connecting end sleeve, so that the stress of the connecting end sleeve is more uniform when it is turned outwards.

[0007] As a preferred, the outer side of the connecting end sleeve is tangent to the outer side of the corrugated close piece, which facilitates demolding after integral molding.

[0008] As a preferred, the outer sides of the connecting end sleeve and the corrugated close piece are provided with continuous adhesive tape grooves, which can prevent the strip-shaped structure wound on the connecting end sleeve from sliding off.

[0009] As a preferred, the side surface of the corrugated close groove and the corrugated close piece matched with each other is corrugated along the axial section of the connecting end sleeve, which can effectively inhibit the axial movement of the corrugated close piece, so that the flatness of the end of the connecting end sleeve can be maintained better.

[0010] As another preferred, the side of the corrugated close groove and the corrugated close sheet mutually fitting along the radial section of the connecting end sleeve is corrugated, which can effectively inhibit the corrugated close sheet from moving along the circumference, so that the wrapping strength of the connecting end sleeve can be kept better.

[0011] Further preferably, the corrugated pipe body and the connecting end sleeve are integrated structures, the materials are uniform, and the structural strength at the transition is high.

[0012] Compared with the prior art, the application has the following beneficial effects:

[0013] (1) By designing the connecting end sleeve structure with a truncated seam at the end of the corrugated pipe, the end of the corrugated pipe can be expanded by everted to enlarge the caliber, making it more convenient for the cable structure to enter the corrugated pipe;

[0014] (2) By designing the corrugated close groove and the corrugated close sheet structure that can cooperate with each other on both sides of the truncated seam, the contraction ability of the end of the corrugated pipe is effectively improved, which can be more fully fitted with the outer surface of the cable or the cable lead-in pipe, thereby improving the waterproof performance of the two ends of the corrugated pipe.
