FIG. 1 is a diagram: the utility model discloses the schematic structure.

In the figure: 1. a polyethylene pipe body; 2. a central tube; 3. a connecting rod; 4. a top plate; 5. an armor layer; 6. an outer protective layer; 7. rubber compression resistance convex strip.

The drawings are for illustrative purposes only and are not to be construed as limiting the patent; for the purpose of better illustrating the embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides a polyethylene pipe of resistance to compression, including polyethylene pipe body 1, the inner chamber middle part of polyethylene pipe body 1 is provided with center tube 2 from inside to outside, the outer wall of center tube 2 is provided with linking pole 3 all around the equidistance, will be corresponding four groups of linking pole 3 that are provided with of outer wall every a section distance of center tube 2, can be overall play the effect of support like this, excessive increase manufacturing cost again, the one end that center tube 2 was kept away from to linking pole 3 all is provided with roof 4, and roof 4 keeps away from the one end of linking pole 3 and the inner wall laminating of polyethylene pipe body 1, the outer wall of polyethylene pipe body 1 cup joints and is provided with armor 5, the outer wall of armor 5 cup joints and is provided with outer protective layer 6.

Wherein: the central tube 2 is a hollow rubber tube, the included angles between the central tube 2 and the connecting rod 3 are all set to be ninety degrees, and the rubber tube has certain flexibility and can be bent along with the bending of the central tube 2, so that the installation is convenient;

the top plates 4 are all arranged to be rubber top plates, the top plates 4 are all arranged to be arc-shaped top plates, rubber bumps are uniformly arranged at one ends, attached to the inner wall of the polyethylene pipe body 1, of the top plates 4, so that the top plates 4 can be attached to one ends of the inner wall of the polyethylene pipe body 1 more tightly, friction force can be increased through the arranged rubber bumps, and connection between the top plates 4 and the polyethylene pipe body 1 is more stable;

the outer wall of the outer protection layer 6 is sequentially and annularly provided with rubber compression-resistant convex strips 7 from inside to outside, and the transverse inclined planes of the rubber compression-resistant convex strips 7 are all in an isosceles trapezoid shape, so that the compression-resistant effect is improved;

armor 5 sets up to steel wire parcel protective layer, increases the effect of resistance to compression.
