Detailed Description

The following description will further describe a high strength modified polypropylene corrugated pipe according to the present invention with reference to the accompanying drawings.

Referring to fig. 1 and 2, a high-strength modified polypropylene corrugated pipe includes an inner pipe 1 and a corrugated outer pipe 2, and is characterized in that: the inner wall of inner tube 1 is equipped with the carbon fiber honeycomb layer 3 that has high strength, carbon fiber honeycomb layer 3 is attached to the inner wall of inner tube 1, because honeycomb has characteristics such as stability is good, intensity height, can increase the internal strength of corrugated pipe body, honeycomb layer 2 is unsmooth type at the inner wall, has reduced the area of contact of cable conductor with the pipe wall when the threading, and then reduces the threading resistance, improves threading efficiency, and the sand grain of attaching to on the cable conductor can also be scraped down to unsmooth type inner wall simultaneously. The outside of corrugated outer tube 2 is equipped with arch 4, arch 4 is the better rubber mass point of elasticity, through the outer wall of secondary extrusion attached to the bellows, and when the body collided with the external world, arch 4 at first contacted with the external world, provides fine cushioning effect for the corrugated body, makes the bellows have fine anti-falling effect when the transport.

Further, referring to fig. 1 and 3, a connecting piece 5 is arranged at one end of the corrugated outer tube 2, the connecting piece 5 is in threaded connection with the corrugated outer tube 2, a fixed core column 501 is integrally formed outside the connecting piece 5, a connecting seat 6 is fixed at the other end of the corrugated outer tube 2 through threads, a mounting hole 601 matched with the fixed core column 501 is formed outside the connecting seat 6, a sealing ring 7 is further arranged outside the connecting seat 6, the connecting piece 5 is mounted in the mounting hole 601 in the connecting seat 6 through the fixed core column 501 during pipeline connection, the sealing ring 7 is sleeved on the tube wall of the corrugated outer tube 2 and locked by a nut, and two corrugated tubes are connected together.

The utility model discloses an assembly process of connecting piece: firstly, the connecting piece 5 and the connecting seat 6 are respectively installed at two ends of the corrugated pipe body through threads, the joint of the two pipe bodies is sealed through the sealing ring 7, the connecting piece 5 is installed on the installing hole 601 on the connecting seat 6 through the fixed core column 501, and then the connecting piece is locked through the nut, so that the two corrugated pipes are connected together.

The above-mentioned embodiment is right the utility model discloses an explanation, it is not right the utility model discloses a limited, any right the scheme after the simple transform of the utility model all belongs to the protection scope of the utility model.
