High cold-bending resistance PVC electrical conduit

Abstract

The utility model discloses a high anti-cold bend PVC electrician sleeve pipe, including inner tube and outer tube, the pipe wall of inner tube includes the high density inner area of up-down symmetry and the low density inner area of left-right symmetry, and the pipe wall of outer tube includes the high density outer area of left-right symmetry and the low density outer area of up-down symmetry, and inner tube and outer tube are integral structure. The utility model discloses through high density inner area and high density outer area common support, ensure that electrician sleeve pipe whole has excellent supporting property, adopt high density inner area and low density outer area position corresponding and reduce high density inner area thickness's design simultaneously, when bending along low density outer area orientation, two sides high density outer area support, the low density outer area of up-down symmetry and the high density inner area of smaller thickness are more easily compressed and stretch and take place deformation, make electrician sleeve pipe have certain bending orientation, and it is more difficult to fold in this orientation and bend, not only have high anti-cold bend, also have the effect of preventing folding.
