Description

TECHNICAL FIELD

[0001] The utility model relates to a corrugated pipe, in particular to an impact-resistant MPP inner circle outer square corrugated pipe. BACKGROUND

[0002] MPP corrugated pipe, full name MPP double-wall corrugated pipe, is a new type of structural wall pipe made of polypropylene (MPP) as the main raw material, using composite reinforced modified special formula and processing technology, MPP corrugated pipe has the advantages of novel structure, high strength, good temperature resistance and the like.

[0003] However, the MPP corrugated pipe at the present stage has some deficiencies, the MPP corrugated pipe has different shapes, among which there is an inner circle outer square corrugated pipe, when the corrugated pipe is placed, the corrugations are always in an exposed state, which is easy to cause foreign matter to be stuck between the corrugations, when the corrugated pipe is bent under stress, the foreign matter is easy to damage the corrugated pipe, and the surface of the corrugated pipe is provided with corrugations, so when the corrugated pipe is not used, the corrugated pipe is easy to bend and deform due to impact, which is not conducive to the stable placement of the corrugated pipe. UTILITY MODEL CONTENTS

[0004] The main purpose of the utility model is to provide an impact-resistant MPP inner circle outer square corrugated pipe, which can effectively solve the problems in the background art.

[0005] To achieve the above-mentioned purpose, the technical scheme adopted by the utility model is as follows:

[0006] An impact-resistant MPP inner circle outer square corrugated pipe, comprising a corrugated pipe body and a rectangular sleeve, the surface of the corrugated pipe body movably sleeved with a rectangular sleeve, the corrugated pipe body comprising a round pipe, a square pipe and a limiting block, the surface of the round pipe fixedly sleeved with a square pipe, the number of the square pipes being several, the rectangular sleeve movably sleeved on the surface of the square pipe, and the upper surface, lower surface and two side surfaces of the square pipe close to the rear being fixedly installed with limiting blocks.

[0007] Further preferably, the inner upper surface, lower surface and two side surfaces of the rectangular sleeve are provided with limiting sliding grooves, and the rectangular sleeve is movably sleeved on the surface of the square pipe.

[0008] Further preferably, the width of the rectangular sleeve is greater than the spacing between the several square pipes, and the width of the rectangular sleeve is equal to the width of the square pipe.

[0009] Further preferably, the limiting block is embedded in the limiting sliding groove.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The utility model discloses a rectangular sleeve is moved to the interval position between square pipes 102, can cover up the interval, so when the corrugated pipe is impacted, the rectangular sleeve can increase the impact resistance of the corrugated pipe body.
