Description

Technical Field

[0001] The utility model relates to the technical field of corrugated pipes, in particular to an antifreeze plastic composite corrugated pipe. Background Art

[0002] Plastic corrugated pipe is a pipe made of plastic as the main raw material. Its wall is corrugated. Common plastic materials include PP, PE, etc. This corrugated pipe is light in weight and easy to transport and install. It has strong corrosion resistance and can withstand the erosion of various chemical substances. At the same time, it also has good insulation and flexibility. It is widely used in many fields such as cable protection and drainage.

[0003] The above-mentioned and existing technologies have the following defects: when the plastic corrugated pipe is used in a low-temperature environment, its material will become brittle. This brittleness will cause the strength of the plastic corrugated pipe to be greatly reduced, and its structure will become fragile. Under the impact of external force, it is very easy to crack, break, etc., seriously affecting its normal use.

[0004] Therefore, an antifreeze plastic composite corrugated pipe is proposed. Utility Model Content

[0005] The utility model aims to solve the disadvantage that plastic corrugated pipes are very likely to crack or break under the impact of external forces, and proposes an antifreeze plastic composite corrugated pipe.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: an antifreeze plastic composite corrugated pipe, comprising a corrugated pipe body, the corrugated pipe body is a polyethylene pipe, the outer arc surface of the corrugated pipe body is fixedly connected to a plurality of rubber columns, one end of the rubber column is fixedly connected to an extension pipe, and the extension pipe is a polycarbonate pipe.

[0007] The effect achieved by the above components is: the bellows body made of polyethylene material has good resistance to low temperature and antifreeze properties. When the bellows body is subjected to external impact, the extension tube will transfer the impact force to the rubber column. The rubber column will deform to absorb the impact energy, thereby buffering the extension tube, reducing the impact of external impact force on the bellows body, and avoiding the bellows body from cracking and damaging in low temperature environments, so that the bellows body can be used normally.

[0008] Preferably, a retaining ring is fixedly connected to the inner wall of the extension tube, and a circular ring is fixedly connected to the outer arc surface of the bellows body, and the circular ring is slidably connected to the retaining ring.

[0009] The effect achieved by the above components is: the retaining ring and the circular ring can cooperate to seal the gap between the extension tube and the bellows body, preventing foreign matter from being stuck between the bellows body and the extension tube, affecting the extension tube's transmission of external impact force to the rubber column.

[0010] Preferably, a cavity is defined in the extension tube.

[0011] The effect achieved by the above components is that the cavity can improve the thermal insulation performance of the extension tube, thereby slowing down the heat loss rate of the bellows body and further improving the antifreeze performance of the bellows body.

[0012] Preferably, a plurality of rubber strips are fixedly connected to the outer arc surface of the extension tube.

[0013] The effect achieved by the above components is that the rubber strip can provide buffering protection against external impacts.

[0014] Preferably, a plurality of protrusions are fixedly connected to the surface of the rubber strip, the protrusions are fixedly connected to the extension tube, and the cross-section of the protrusions is an isosceles trapezoid.

[0015] The effect achieved by the above components is that the protrusion can improve the connection strength between the extension tube and the rubber strip, thereby improving the stability of the rubber strip.

[0016] Preferably, a steel mesh is fixedly connected to the bellows body.

[0017] The effects achieved by the above components are: the steel wire mesh can improve the strength of the bellows body and prevent the bellows body from being broken.

[0018] Compared with the prior art, the advantages and positive effects of the present invention are:

[0019] In the utility model, the bellows body made of polyethylene material has good resistance to low temperature and antifreeze properties. When the bellows body is subjected to external impact, the extension tube will transfer the impact force to the rubber column, and the rubber column will deform to absorb the impact energy, thereby buffering the extension tube, reducing the impact of external impact force on the bellows body, and avoiding the bellows body from cracking and breaking in a low temperature environment, so that the bellows body can be used normally.
