To exist not enough among the prior art, the utility model provides a double-walled spiral cavity mysterious compound pipe of moulding, it has solved among the prior art that the compound pipeline outer wall has the bulge to receive the impact easily and leads to cracked problem.

According to the utility model discloses an embodiment, a double-walled spiral cavity mysterious moulding composite pipe, it includes first pipe wall layer, and the first pipe wall layer is encircleed outward and is provided with a plurality of spiral ribs, and all spiral rib outsourcing are provided with second pipe wall layer, and each spiral rib meets with first pipe wall layer and second pipe wall layer respectively in order to separate first pipe wall layer and second pipe wall layer apart.

In the above embodiment, the second pipe wall layer is equivalent to the outer pipe in the prior art, but the second pipe wall layer is not provided with the bulge, but the cavity formed by the spiral ribs between the first pipe wall layer and the second pipe wall layer plays a role in buffering, and the bulge is not provided, so that the problem that the bulge on the outer wall of the composite pipe in the prior art is easily impacted to cause rupture is solved.

Further, the spiral rib comprises a first embedded part and a second embedded part, and the first embedded part and the second embedded part are embedded in the first pipe wall layer and the second pipe wall layer respectively.

Further, the first and second embedded portions are both T-shaped.

Furthermore, a plurality of connecting rings are arranged between the first pipe wall layer and the second pipe wall layer, the connecting rings are separated from the first pipe wall layer and the second pipe wall layer, and each connecting ring is connected with all the spiral ribs.

Further, all connection rings are equally spaced.

Further, all the spiral ribs are equally spaced.

Compared with the prior art, the utility model discloses following beneficial effect has:

the adopted first pipe wall layer is equivalent to an inner pipe in the prior art, a plurality of spiral ribs are arranged between the first pipe wall layer and the second pipe wall layer, and the spiral ribs support the first pipe wall layer and the second pipe wall layer to form a plurality of spiral cavities, so that the spiral cavities play a role in buffering, meanwhile, no convex part exists outside the second pipe wall layer, and the second pipe wall layer integrally bears pressure impact, so that the probability of breakage of the second pipe wall layer is reduced compared with an outer pipe in the prior art.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and for simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

As shown in fig. 1 and 2, the present embodiment provides a double-wall spiral hollow corrugated plastic composite pipe, which includes a first pipe wall layer 1, a plurality of spiral ribs 2 surrounding the first pipe wall layer 1, a second pipe wall layer 3 wrapping all the spiral ribs 2, and each spiral rib 2 is respectively connected to the first pipe wall layer 1 and the second pipe wall layer 3 to separate the first pipe wall layer 1 and the second pipe wall layer 3.

In the above embodiment, the first pipe wall layer 1 corresponds to an inner pipe in the prior art, and the second pipe wall layer 3 corresponds to an outer pipe in the prior art, but the second pipe wall layer 3 is not provided with a bulge, but a cavity is formed by the spiral ribs 2 between the first pipe wall layer 1 and the second pipe wall layer 3 to play a role in buffering, and because no bulge is provided, the second pipe wall layer 3 is subjected to pressure impact as a whole, so that the probability of rupture of the second pipe wall layer 3 is reduced compared with the outer pipe in the prior art, that is, the problem that the outer wall of the composite pipe in the prior art is easily ruptured due to impact caused by the bulge is avoided.
